BACKGROUND OF THE INVENTION

[0002] Analyte monitoring devices have been used as medical diagnostic devices to determine a level of analyte from a sample. One common application is glucose measurements. For example, an analyte monitoring device is used with a remote sensor to perform an analyte reading. The sensor may be configured for implantation (e.g., subcutaneous, venous, or arterial implantation) into a patient. The analyte monitoring device processes signals from the remote sensor to determine the concentration or level of analyte in the subcutaneous tissue and may display the current level of the analyte.

DETAILED DESCRIPTION OF THE INVENTION

[00106] Before the present inventions are described, it is to be understood that this invention is not limited to particular aspects described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only, and is not intended to be limiting, since the scope of the present invention will be limited only by the appended claims.

[00107] Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limits of that range is also specifically disclosed. Each smaller range between any stated value or intervening value in a stated range and any other stated or intervening value in that stated range is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included or excluded in the range, and each range where either, neither or both limits are included in the smaller ranges is also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022 one or both of the limits, ranges excluding either or both of those included limits are also included in the invention.

[00108] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, some potential and preferred methods and materials are now described.

It is understood that the present disclosure supercedes any disclosure of an incorporated publication to the extent there is a contradiction.

[00109] It must be noted that as used herein and in the appended claims, the singular forms a, an, and the include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to a program update includes a plurality of such program updates and reference to the program update includes reference to one or more program updates and equivalents thereof known to those skilled in the art, and so forth.

[00110] Generally, embodiments of the present disclosure relate to in vivo methods and devices for detecting at least one analyte such as glucose in body fluid. Accordingly, embodiments include in vivo analyte sensors configured so that at least a portion of the sensor is positioned in the body of a user (e.g., within the ISF), to obtain information about at least one analyte of the body, e.g., transcutaneously positioned in user’s body. In certain embodiments, an in vivo analyte sensor is coupled to an electronics unit that is maintained on the body of the user such as on a skin surface, where such coupling provides on body, in vivo analyte sensor electronics assemblies.

[00111] In certain embodiments, analyte information is communicated from a first device such as an on body electronics unit to a second analyte monitoring device which may include user interface features, including a display, and/or the like.

[00112] In many embodiments of the system, analyte information derived by the sensor/on body electronics (for example, on body electronics assembly) is made available in a user-usable or viewable form only when queried by the user such

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022 that the timing of data communication is selected by the user. The on-body electronics may take periodic measurement and record such data until an ondemand reading is taken by the user (e.g., the display device brought in close vicinity of the on-body electronics and sensor). Upon communication, the onbody electronics may communicate the recorded data for a set time period. For example, the on-body electronics may have 8 hours of memory in which it stores periodic measurements taken every 15 minutes. When an on-demand reading is taken, the entire 8 hours is transferred to the device. It should be appreciated that if the user does not take an on-demand reading for longer than 8 hours, some of the data may be lost.

[00113] Accordingly, in certain embodiments once a sensor electronics assembly is placed on the body so that at least a portion of the in vivo sensor is in contact with bodily fluid such as ISF and the sensor is electrically coupled to the electronics unit, sensor derived analyte information may be communicated from the on body electronics to a display device on-demand by powering on the display device, and executing a software algorithm stored in and accessed from a memory of the display device, to generate one or more request commands, control signal or data packet to send to the on body electronics. The software algorithm executed under, for example, the control of the microprocessor or application specific integrated circuit (ASIC) of the display device may include routines to detect the position of the on body electronics relative to the display device to initiate the transmission of the generated request command, control signal and/or data packet.

[00114] Display devices may also include programming stored in memory for execution by one or more microprocessors and/or ASICs to generate and transmit the one or more request command, control signal or data packet to send to the on body electronics in response to a user activation of an input mechanism on the display device such as depressing a button on the display device, triggering a soft button associated with the data communication function, and so on. The input mechanism may be alternatively or additionally provided on or in the on body electronics which may be configured for user activation. In certain embodiments, voice commands or audible signals may be used to prompt or instruct the microprocessor or ASIC to execute the software routine(s) stored in the memory to generate and transmit the one or more request

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022 command, control signal or data packet to the on body device. In the embodiments that are voice activated or responsive to voice commands or audible signals, on body electronics and/or display device includes a microphone, a speaker, and processing routines stored in the respective memories of the on body electronics and/or the display device to process the voice commands and/or audible signals. In certain embodiments, positioning the on body device and the display device within a predetermined distance (e.g., close proximity) relative to each other initiates one or more software routines stored in the memory of the display device to generate and transmit a request command, control signal or data packet.

[00115] Different types and/or forms and/or amounts of information may be sent for each on demand reading, including but not limited to one or more of current analyte level information (i.e., real time or the most recently obtained analyte level information temporally corresponding to the time the reading is initiated), rate of change of an analyte over a predetermined time period, rate of the rate of change of an analyte (acceleration in the rate of change), historical analyte information corresponding to analyte information obtained prior to a given reading and stored in memory of the assembly. Some or all of real time, historical, rate of change, rate of rate of change (such as acceleration or deceleration) information may be sent to a display device for a given reading. In certain embodiments, the type and/or form and/or amount of information sent to a display device may be preprogrammed and/or unchangeable (e.g., preset at manufacturing), or may not be preprogrammed and/or unchangeable so that it may be selectable and/or changeable in the field one or more times (e.g., by activating a switch of the system, etc). Accordingly, in certain embodiments, for each on demand reading, a display device will output a current (real time) sensor-derived analyte value (e.g., in numerical format), a current rate of analyte change (e.g., in the form of an analyte rate indicator such as a arrow pointing in a direction to indicate the current rate), and analyte trend history data based on sensor readings acquired by and stored in memory of on body electronics (e.g., in the form of a graphical trace). Additionally, the on skin or sensor temperature reading or measurement associated with each on demand reading may be communicated from the on body electronics to the display device. The temperature reading or measurement, however, may not be output or displayed

PCT/US2012/027022 on the display device, but rather, used in conjunction with a software routine executed by the display device to correct or compensate the analyte measurement output to the user on the display device.

[00116] As described, embodiments include in vivo analyte sensors and on body electronics that together provide body wearable sensor electronics assemblies (also referred to herein as a “patch”). In certain embodiments, in vivo analyte sensors are fully integrated with on body electronics (fixedly connected during manufacture), while in other embodiments they are separate but connectable post manufacture (e.g., before, during or after sensor insertion into a body). On body electronics may include an in vivo glucose sensor, electronics, battery, and antenna encased (except for the sensor portion that is for in vivo positioning) in a waterproof housing that includes or is attachable to an adhesive pad.

[00117] Embodiments include sensor insertion devices, which also may be referred to herein as sensor delivery units, or the like. Insertion devices may retain on body electronics assemblies completely in an interior compartment, i.e., an insertion device may be “pre-loaded” with on body electronics assemblies during the manufacturing process (e.g., on body electronics may be packaged in a sterile interior compartment of an insertion device). In such embodiments, insertion devices may form sensor assembly packages (including sterile packages) for pre-use or new on body electronics assemblies, and insertion devices configured to apply on body electronics assemblies to recipient bodies.

[00118] Embodiments include portable handheld display devices, as separate devices and spaced apart from an on body electronics assembly, that collects information from the assemblies and provide sensor derived analyte readings to users. Such devices may also be referred to as meters, readers, monitors, receivers, human interface devices, companions, or the like. Certain embodiments may include an integrated in vitro analyte meter. In certain embodiments, display devices include one or more wired or wireless communications ports such as USB, serial, parallel, or the like, configured to establish communication between a display device and another unit (e.g., on body electronics, power unit to recharge a battery, a PC, etc).

[00119] Compatible informatics software in certain embodiments include, for example, but not limited to stand alone or network connection enabled data management software program, resident or running on a display device,

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022 personal computer, a server terminal, for example, to perform data analysis, charting, data storage, data archiving and data communication as well as data synchronization. Informatics software in certain embodiments may also include software for executing field upgradable functions to upgrade firmware of a display device and/or on body electronics unit to upgrade the resident software on the display device and/or the on body electronics unit, e.g., with versions of firmware that include additional features and/or include software bugs or errors fixed, etc.

[00120] Embodiments may include a haptic feedback feature such as a vibration motor or the like, configured so that corresponding notifications (e.g., a successful on-demand reading received at a display device), may be delivered in the form of haptic feedback.

[00121] Embodiments include programming embedded on a computer readable medium, i.e., computer-based application software (may also be referred to herein as informatics software or programming or the like) that processes analyte information obtained from the system and/or user self-reported data. Application software may be installed on a host computer such as a mobile telephone, PC, an Internet-enabled human interface device such as an Internetenabled phone, personal digital assistant, or the like, by a display device or an on body electronics unit. Informatics programming may transform data acquired and stored on a display device or on body unit for use by a user.

[00122] Embodiments of the subject disclosure are described primarily with respect to glucose monitoring devices and systems, and methods of glucose monitoring, for convenience only and such description is in no way intended to limit the scope of the disclosure. It is to be understood that the analyte monitoring system may be configured to monitor a variety of analytes at the same time or at different times.

[00123] For example, analytes that may be monitored include, but are not limited to, acetyl choline, amylase, bilirubin, cholesterol, chorionic gonadotropin, creatine kinase (e.g., CK-MB), creatine, DNA, fructosamine, glucose, glutamine, growth hormones, hormones, ketones, lactate, oxygen, peroxide, prostatespecific antigen, prothrombin, RNA, thyroid stimulating hormone, and troponin. The concentration of drugs, such as, for example, antibiotics (e.g., gentamicin, vancomycin, and the like), digitoxin, digoxin, drugs of abuse, theophylline, and

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022 warfarin, may also be monitored. In those embodiments that monitor more than one analyte, the analytes may be monitored at the same or different times, with a single sensor or with a plurality of sensors which may use the same on body electronics (e.g., simultaneously) or with different on body electronics.

[00124] As described in detail below, embodiments include devices, systems, kits and/or methods to monitor one or more physiological parameters such as, for example, but not limited to, analyte levels, temperature levels, heart rate, user activity level, over a predetermined monitoring time period. Also provided are methods of manufacturing. Predetermined monitoring time periods may be less than about 1 hour, or may include about 1 hour or more, e.g., about a few hours or more, e.g., about a few days of more, e.g., about 3 or more days, e.g., about 5 days or more, e.g., about 7 days or more, e.g., about 10 days or more, e.g., about 14 days or more, e.g., about several weeks, e.g., about 1 month or more. In certain embodiments, after the expiration of the predetermined monitoring time period, one or more features of the system may be automatically deactivated or disabled at the on body electronics assembly and/or display device.

[00125] For example, a predetermined monitoring time period may begin with positioning the sensor in vivo and in contact with a body fluid such as ISF, and/or with the initiation (or powering on to full operational mode) of the on body electronics. Initialization of on body electronics may be implemented with a command generated and transmitted by a display device in response to the activation of a switch and/or by placing the display device within a predetermined distance (e.g., close proximity) to the on body electronics, or by user manual activation of a switch on the on body electronics unit, e.g., depressing a button, or such activation may be caused by the insertion device, e.g., as described in U.S. Patent Application No. 12/698,129 filed on February 1,2010 and U.S. Provisional Application Nos. 61/238,646, 61/246,825, 61/247,516, 61/249,535, 61/317,243, 61/345,562, and 61/361,374.

[00126] When initialized in response to a received command from a display device, the on body electronics retrieves and executes from its memory software routine to fully power on the components of the on body electronics, effectively placing the on body electronics in full operational mode in response to receiving

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022 the activation command from the display device. For example, prior to the receipt of the command from the display device, a portion of the components in the on body electronics may be powered by its internal power supply such as a battery while another portion of the components in the on body electronics may be in powered down or low power including no power, inactive mode, or all components may be in an inactive mode, powered down mode. Upon receipt of the command, the remaining portion (or all) of the components of the on body electronics is switched to active, fully operational mode.

[00147] In some aspects, the display device (also referred to herein as “analyte monitoring device” or simply “device”) is configured to receive a signal from a remote sensor using radio-frequency identification (RFID) technology.

[00148] This configuration may be used to provide glucose on demand capabilities, for example, in which case when a measurement reading is desired, the analyte monitoring device is brought within close vicinity of the implantable sensor. It should be appreciated that in other embodiments the wireless communication unit may communicate with the sensor using a different wireless communication technology than RFID. When within range, the device may be configured to verify that the sensor is the appropriate sensor that it has been configured to operate with. If not, the device ignores the sensor and does not initiate operation with the sensor. If so, the device initiates operation with the sensor.

[00149] The analyte monitoring device may perform a variety of functions, including for example: modifying the signals from the sensor using calibration data and/or measurements from a temperature probe (not shown); determining a level of an analyte in the interstitial fluid; determining a level of an analyte in the bloodstream based on the sensor measurements in the interstitial fluid; determining if the level, rate of change, and/or acceleration in the rate of change of the analyte exceeds or meets one or more threshold values; activating an alarm system if a threshold value is met or exceeded; evaluating trends in the level of an analyte based on a series of sensor signals; therapy management (e.g., determine a dose of a medication, etc.); and reduce noise or error contributions (e.g., through signal averaging or comparing readings from multiple electrodes); etc. The analyte monitoring device may be simple and perform only one or a small number of these functions or the analyte monitoring device may perform all or most of these functions.

Software for the Remote Device

[00150] In some aspects, the analyte monitoring device may be communicatively coupled to a remote data processing device for management purposes. Remote device may include, for example, a personal computer, laptop, PDA, cellular

PCT/US2012/027022 phone, smartphone, set-top box, etc. The remote device may include, for example, a control unit including any variety of processor, microprocessor, microcontroller, etc. The remote device may also include a memory unit comprising non-volatile memory and volatile memory.

[00151] The term “remote device” is used herein to represent any device that is external to the analyte monitoring device. The remote device may require software to fully communicate with the analyte monitoring device, manage data from the analyte monitoring device, modify settings on the analyte monitoring device, or otherwise operate with analyte monitoring device. This auto-assisting user interface software is referred to herein as “remote device software” or “RD software” or “Auto-Assist software” to distinguish it from the user interface software running on the analyte monitoring device. The RD software may be obtained from one or more methods such as downloading from the web, CDROM, memory stick, etc. The RD software is generally discussed here and additional details regarding various flows and screens are provided later.

[00152] In some embodiments, the analyte monitoring device includes the RD software programs and/or applications to be run on the remote device. In some instances, the RD software may be configured to automatically launch when the analyte monitoring device is coupled to the computer. For example, the analyte monitoring device may include an installer program that is stored in non-volatile memory and executed when the analyte monitoring device is coupled to the remote device. The installer program may be executed when the user couples the analyte monitoring device to the remote device. The installer program may then initiate the launch of the RD software on the remote device.

[00153] In some embodiments, the RD software is not stored in non-volatile memory on the remote device. The RD software is stored on the analyte monitoring device and used to launch the RD software on the remote device is coupled to the analyte monitoring device.

[00154] In some embodiments, the RD software may be downloaded and stored in non-volatile memory on the remote device. For example, the RD software may be downloaded via a network connection (e.g., via an internet connection), by storage device (e.g., CD-ROM, memory stick, etc.), and/or downloaded from the analyte monitoring device. In some instances, the RD software is capable of being run even when the device is not coupled to the computer.

PCT/US2012/027022

[00155] It should be understood that the RD software may be compatible with various hardware systems (e.g., PC, MAC) and various operating systems (e.g., Windows, MAC OS, Linux).

[00156] The analyte monitoring device may be communicatively coupled to the remote device via wired technologies. Example wired technologies may include, but are not limited to, the following technologies, or family of technologies: USB, FireWire, SPI, SDIO, RS-232 port, etc.

[00157] The analyte monitoring device may include, for example, a communication connector unit to permit wired communication and coupling to the remote device. The communication connector unit provides the capability to communicate with a remote device having an appropriate interface to operatively couple with the communication connector. In some embodiments, the communication connector is configured to communicate with a smartphone such as an iPhone or Blackberry.

[00158] The communication connector unit may be any variety of connection interfaces—e.g., male or female connection interfaces. Using USB as an example, the communication connector may be any of the variety of USB plugs or USB receptacles/ports. As USB receptacles are typically located on computer and other devices, a corresponding USB plug used as a communication connector unit will enable the analyte monitoring device to be plugged directly into the USB receptacle, avoiding the use of cables. In other instances, the appropriate USB receptacle may be used on the analyte monitoring device to enable communication using a USB cable (similar to many other devices such as digital cameras, cellular phones, smartphones, etc.).

[00159] It should be appreciated that the in some embodiments the analyte monitoring device may be communicably coupled to the remote device via wireless technology.

Example Devices & Systems

[00168] FIG. 2 illustrates a block diagram of a system including an analyte monitoring device and remote data processing device, according to some embodiments. System 1500 is shown to comprising analyte monitoring device 1501 communicably coupled to remote device 1505. In some instances, as shown, remote device 1505 may have network access to a network 1510 in which a second remote device 1515 is shown coupled to. It should be understood that network 1510 may include one or more networks, including LANs, WANs, and/or the internet.

[00169] Analyte monitoring device 1501 is shown removably coupled to remote device 1505 via communication connector unit 1422. Communication connector unit, for example, includes a USB plug which couples with a USB receptacle 1507 in remote device 1505. Remote device 1505 may include peripheral devices, such as printer, keyboard, monitor, CD drive, etc. Remote device 1505 may also include, as shown, a network interface 1530 which connects it to network 510. Remote device 1515 is also connected to network 1510 and may communicate with remote devicel 505 via network 1510.

[00170] The following paragraphs describe system 1500 during operation, according to some embodiments. In some instances, the analyte monitoring device described is a glucose monitoring device which measures the glucose concentration level of a blood sample. It should be understood that the description applies equally to other analytes and to other forms of samples.

[00171] In use, analyte monitoring device 1501 receives a test strip 1525 for measuring an analyte level of a sample applied to test strip 1525. Test strip 1525 is received at strip port unit 1520. Analyte monitoring device 1501 performs a measurement computation on the sample and the user can view the measurement reading on, for example, a touchsreen display (not shown). The user may also be presented with a menu on the touchscreen display to view and select—e.g., menus for storing data, downloading data, performing bolus calculations based on the measurement, etc.

[00172] The user may couple the analyte monitoring device 1501 to remote device 505 (e.g., a personal computer) via a communication connector unit. For example, the user may decide to store the measurement data and then choose to download stored test data (including stored measurement readings) to a remote device 1505.

[00173] Analyte monitoring devicel 501 may then be coupled to remote device 1505 via communication connector unit 1422. Communication connector unit 1422 may, for example, include a USB plug which couples to a USB receptacle 1507 on remote device 1505.

[00174] In some instances, the analyte monitoring device 1501 may be powered by the remote device 1505 when coupled via the communication connector unit 1422. In such case, the user would couple the analyte monitoring device 1501 to the remote device 1505 and then insert test strip 1525 into the strip port 1520 to take a measurement reading. In some instances, the analyte monitoring device includes its own power source, such as button or AAA-size batteries, for example, and is not powered by the remote device 1505.

[00175] In some instances, the analyte monitoring device may be “locked” or prevented from performing a test while coupled to the remote device 1505. For example, medical device regulations such as high voltage isolation testing may be required if the analyte monitoring device is configured to perform tests while coupled to a remote device. Thus, “locking” or preventing the analyte monitoring device from performing a test while coupled to the remote device allows the analyte monitoring device to not be subjected to the additional testing, if so desired.

[00176] In some aspects, the analyte monitoring device 1501 may initiate a user interface application (e.g., RD software) to execute on the analyte monitoring

PCT/US2012/027022 device, and/or the remote device 1505 when coupled to the remote device 1505. The user interface application may be stored in a memory unit on the analyte monitoring device 1501, for example. In some aspects, the user is not required to have previously loaded software on the remote device 1505 to operate with the analyte monitoring device 1501. In some aspects, the analyte monitoring device may be configured to initiate the user interface application automatically upon coupling to the remote device. It should be understood that the user interface application may be configured to be compatible with various hardware systems (e.g., PC, MAC) and various operating systems (e.g., Windows, MAC OS, Linux).

[00177] The user interface application may include, for example, diabetes management related applications. The user interface application may provide a variety of menus, selections, charts, alarms, reminders, visual indicators, etc. For example, the user may be presented with menus and options, such as whether to take a measurement reading, to view stored measurement readings, to store data, to download data, to perform bolus calculation based on the measurement, etc.

[00178] The user interface program may, for example, allow the user to perform the following steps: (1 ) create a replica of the test data stored on the analyte monitoring device 1501, on the remote device 1505; and (2) synchronize test data from the analyte monitoring device 1501 to the database on the remote device 1505. Meter settings and/or user settings/preferences from the analyte monitoring device may also be included in the test data and synchronized with the remote device. Date and time for the remote device 1505 and analyte monitoring device 1501 may also be synched.

[00179] To read test data from the analyte monitoring device 1501 and write it to the remote device 1505, it is recognized herein that data in the remote device may be organized into tables, which may be organized into records, which may be broken down into predefined fields. Similarly, at some level data will be organized into records with a consistent field structure on the analyte monitoring device 1501. The user interface application may read test data from the analyte monitoring device and write it out to tables on the remote device 1505. The user interface application may also read data from table in the remote device 1505 and write them out to the analyte monitoring device 1501. Various types of data

For example, data residing in fields in the analyte monitoring device may be converted from the format it exists in the analyte monitoring device to a format compatible with the remote device, and vice versa. The logical structure of the records in the two systems may be different.

[00180] Remote device 1505 may include peripheral devices, such as printer, keyboard, monitor, CD drive, etc. Remote device 1505 includes a network interface which connects it to network 1510 (e.g., the internet). The user interface application may provide the user with the option to view test data on the monitor, to store test data on storage media (e.g., CD-ROM, memory card, etc.), further analyze and/or manipulate test data, transmit data to another device), and/or print out test data such as charts, reports, etc., on the printer.

[00181] As shown, remote device 1505 may also include a network interface 1530 (e.g., network interface card (NIC), modem, router, RF front end, etc.) used to connect the remote device 1505 to network 1510. For example, in some aspects, analyte monitoring device 1501 may couple via a USB connection to the remote device which may be a personal computer or laptop connected to the internet using a wireless modem and/or router. In some aspects, analyte monitoring device 1501 may couple via a micro USB connection to a remote device 1505 which is a smartphone having an RF front end to access a mobile network. The user interface application may provide a user interface for using the network connection of the remote device 1505—e.g., to forward test data to a physician, hospital, health provider, and/or other third party located at a second remote device 1515 on network 1510. Appropriate action may then be taken by the receiving party at the second remote device 1515.

[00244] FIG. 7 illustrates a method 260 for activating a sensor after the device is powered on, according to one embodiment. At block 262, the device is powered on. Once powered, a home screen 264 is displayed. The home screen 264 indicates that there is no active sensor, and further includes an icon or other trigger element 265 that enables the start of a new sensor. Once icon 265 is selected by the user, as represented by block 266, a “Start New Sensor” screen 268 for starting the sensor is displayed. The start new sensor screen 268 enables the user to start a new sensor—e.g., by informing the user to scan the sensor to start it. The user may then scan a sensor to start a pairing, as indicated by block 270. If an expired sensor is scanned, the device may display a screen indicating the sensor is expired. If the scan fails, the device may display a screen informing the user that the scan failed.

[00245] In some instances, the device may include a masked mode that enables the user to take readings of a paired sensor, but does not display the resulting readings to the user, or otherwise limits the resulting data to the user. As shown by reference pathway B, after a non-expired sensor has been successfully scanned, the device may display a masked mode screen to indicate or configure a masked mode. For example, masked mode screen 272 indicates that the device will operate in the masked mode, unless otherwise changed by the user. Screen 272 enables the user to make a selection and be taken to a settings screen to edit the masked mode setting, as shown at block 274. In some instances, the initial configuration may be set up by the doctor or other health care profession for the patient. If the user wishes to remain in the masked mode, then it may be determined if the sensor has been already activated, as shown at block 276.

[00246] If the sensor has not been previously activated by another analyte monitoring device, then a warmup message screen 282 is displayed that indicates that the sensor is warming up. The remaining time may also be displayed. If the user confirms the message, for example by selecting the “ok” icon, then the home screen 284 is displayed and indicates the sensor is warming

[00249] FIG. 8 illustrates a method 290 for scanning a sensor with an analyte monitoring device, according to one embodiment. At block 292, the device is powered on. A scan prompt screen 294 is displayed and indicates to the user to scan the sensor to check an analyte level (e.g., glucose level).

[00250] In the embodiment shown, an icon or trigger element is provided on screen 294 for going to the home screen 296. If selected by the user, the home screen 296 is displayed. From the home screen 296, the user may initiate a sensor scan thereafter and return to the scan prompt screen 294.

[00251] If a sensor is scanned, as shown at block 298, it is determined if the scan is successful, as shown at block 300. If the scan is not successful, it is determined whether there was an error or whether the sensor was deactivated, as shown at block 302. If there was an error, then a scan error screen 304 is displayed indicating to the user that an error occurred. If the sensor was deactivated, then a start sensor again screen 306 may be displayed to enable the user to restart the sensor. If it is determined that the sensor has fallen out, then a sensor fall out screen 308 is displayed and indicates that the sensor may have fallen loose and that a new sensor may be required. Screens 304, 306, and 308, provide a user confirmation element—e.g., an “ok” element. Upon selection, the home screen 296 is displayed.

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022

[00252] Returning to block 300, if the scan is successful, then it is determined whether the sensor is new and has not been previously activated, as represented by reference pathway C and block 310. If the sensor is a new inactive sensor, then a new sensor detected screen 312 is shown and indicates that the sensor is a new sensor. Screen 312 provides the user with an option to start the new sensor or not. If the user elects to start the new sensor, then the device initiates the sensor activation process, as shown by block 316. If the user elects to not start the new sensor, then the device displays the home screen, as shown by block 314.

[00253] Returning to block 310, if the scanned sensor is determined to not be a new inactive sensor, then it is determined if the sensor is the current sensor paired with the device, as shown at block 318. If the sensor is not the current sensor for the device, and is instead already paired with another device, then a screen 320 is displayed that indicates that the sensor is already in use with another device and is not the current sensor for this device. Upon user confirmation, the home screen is displayed, as shown at block 322. If at block 318, it is determined that the sensor is the current sensor paired with the device, then it is determined if the sensor is expiring within a predetermined amount of time—e.g., 3 days in the embodiment shown—as shown by block 324. It should be appreciated that the amount of time may vary in other embodiments, and in one embodiment check to see if the sensor is expired. It should also be appreciated that the predetermined amount of time may be preprogrammed in manufacturing, and/or set within the settings, etc.

[00254] If at block 324, it is determined that the sensor is expiring within the predetermined amount of time, then a sensor near expiration screen 326 is displayed to indicate the sensor is close to expiring. The remaining time until the sensor expires may be displayed, for example.

[00255] If at block 324, it is determined that the sensor is not expiring within the predetermined amount of time, then it is determined whether the sensor battery is low, as represented by reference pathway D and block 328. If the battery is low, then at block 330, the device indicates that the battery is low—e.g., via a low battery screen, or a low battery icon, etc. In some instances, a reading is not taken and no results are shown for the scan.

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022

[00256] If the battery is not low, then at block 332, it is determined if the skin temperature is too hot or cold—e.g., using a “safe” range of temperatures. The sensor may provide the temperature data to the device. If the temperature is determined to be too hot or cold, then the device displays the resulting reading and indicates that the sensor temperature was too hot or too cold, respectively, as shown at block 334.

[00257] If the skin temperature is not too hot or cold, then it is determined whether the resulting reading is out of range, as shown at block 336.

[00258] If the sensor is out of range, then it is determined if a high or low glucose condition has occurred, as shown at block 340. For example, a target range or acceptable range may be preset by the manufacturer or customizable by the user. If a high or low condition is present, then the user is taken to the Sensor Results screen and the high or low condition may be indicated on the Sensor Results screen (e.g., via a message, icon, etc.) along with the sensor results, as shown at block 342.

[00259] If a high or low condition is not present, then it is determined whether a high or low condition is projected, as shown at block 344. A high or low condition may be projected, for example, by trends in the measurement readings. If a high or low condition is projected, then the user is taken to the Sensor Results screen and the projected high or low condition is indicated on the Sensor Results screen along with the sensor results, as shown at block 346.

[00260] In some instances, the device is programmed such that the skin temperature test takes priority over other test conditions (e.g., out-of-range test, high/low glucose test, projected high/low glucose test, etc.) that may occur simultaneously.

After the first scan is performed, a Sensor Results screen is displayed, as shown at block 352. If the power is turned off or the Sensor Results screen is left before a predetermined period of time (e.g., 3 minutes in the example embodiment shown), the results from the first scan are saved, as represented by block 354. If the device is powered back on, or another scan is attempted, within the predetermined period of time, the device will prevent the user from performing a new scan and display a No New Scan screen indicating that the a new sensor reading is not available at this time., as shown by blocks 356 and 358. The No New Scan screen may also indicate the time remaining until another scan, as well as, enable the user to view the last Sensor Results screen if desired, as represented by Sensor Results screen 362.

Device Timeout at the Suggest Dose Screen from BG Result

[00264] In some aspects, the analyte reader device is programmed to return to a saved suggested dose screen if the reader is powered off or leaves a “Calculator/Suggested Dose” screen when a dose has been calculated but not logged, and the device is powered back on or another scan is attempted within a predetermined period of time.

[00265] FIG. 9B illustrates a method 364 of logging a dose calculation, according to one embodiment. After a glucose reading is taken, a “Calculator/Suggested Dose” (CALC SGTD) screen 366 may be displayed to calculate and log a suggested dose of insulin. From screen 366, the user can adjust the suggested does if desired and log the dose. However, if within a predetermined period of time (e.g., 3 minutes in the embodiment shown), the device is powered off, or screen 366 is left, after a suggested dose has been calculated but not logged, then the suggested dose data is saved, as shown at block 368. If the device is powered back on, or another glucose scan is attempted, within the predetermined period of time, as shown by block 370, then the user is returned to the CALC SGTD screen 372 having the saved suggested dose data. From here, the user may continue with the dose calculation and log the calculated dose. If a dose is logged at this point, the dose is stored within the Logbook along with the test results. In one embodiment, the dose is logged as having been taken at the time the test was taken rather than at the time the dose was

Suggested Dose from BG Result Logged

[00266] In some aspects of the present disclosure, after a first scan and calculated insulin dose logged, the device is programmed to prevent a second scan within a predetermined period of time from a first scan. The user will not be able to perform the second scan, but will be able to view the Logbook.

[00267] FIG. 9C illustrates a method 374 for enabling two consecutive scans, according to one embodiment. At block 376, the reader is powered off, or the Sensor Results screen is left, within a predetermined period of time after a first scan was taken (e.g., 3 minutes in the embodiment shown). If the device is powered back on, or another scan is attempted, within the predetermined period of time from the first scan, as shown at block 378, then the second scan is prevented from occurring until the predetermined period of time has lapsed. A No New Scan screen 380 is displayed indicating that another scan is not currently permitted. In some instances, as shown, screen 380 provides the time remaining until the another scan can be taken. In the embodiment shown, user confirmation form screen 380 takes the user to the Home screen as shown at block 382. Screen 380 may also provide a selection to allow the user to view the last reading in the Logbook, as shown at block 384.

[00271] In one embodiment, graph 389b displays the past resulting readings for a given time period. The total time period may be sectionalized into a first predetermined period of time 389d, and a second predetermined period of time 389f. The second predetermined period 389f is subsequent to the first predetermined period of time 389d and includes more recent readings than the first predetermined period of time389d. For example, in the embodiment shown, at time 10:23pm, graph 389b displays readings in a first predetermined time period 389d of 8 hours (e.g., 2pm to 10pm), and also displays more recent readings within the second predetermined time period 389f of 1 hour (e.g., 10pm to 11 pm). As graph 389b is displayed at 10:23pm, readings for the last 23 minutes (e.g., 10pm to 10:23pm) are shown in the second predetermined time period 389f. As subsequent readings are taken, graph 389b will track the readings within the second predetermined time period 389f. Once subsequent readings are taken for the entire second predetermined period of time 389f, the entire plot of readings are shifted in time by the second predetermined period of time 389f (e.g., 1 hour). In other words, once subsequent readings are obtained up to 11pm, the plot of readings from 3pm to 11 pm will shift to the first predetermined period of time 389d, and the second predetermined time period 389f will begin without any readings and start to track subsequent readings between 11 pm and 12pm. Once subsequent readings are obtained up to 12pm, then entire plot of readings are again shifted by the second predetermined period of time 389f (e.g., 1 hour), and the process repeats.

[00272] In one embodiment, when scanning is first started and no data has been obtained for the graph 389b, the graph 389b is not displayed until the device has obtained sensor readings for at least the first predetermined period of time 389d (e.g., 8 hours).

[00273] Thus, graph 389b begins with readings for at least the entire first predetermined period of time 389d. For example, in one embodiment, this threshold time period is equal to the first predetermined period of time 389d. In another embodiment, the threshold time period is longer than the first

WO 2012/154286

PCT/US2012/027022 predetermined period of time such that sensor readings have been obtained for part or all of the second predetermined period of time.

[00274] It is appreciated that in other embodiments, a template of the graph may be displayed at first, but no sensor readings are shown on the graph until the device has obtained sensor readings for at least the first predetermined period of time 389d.

Non-Actionable Reading

[00275] FIG. 10B illustrates an example Results Non-Actionable screen 388, according to one embodiment. When a scan is performed and the resulting reading is non-actionable, a Results Non-Actionable screen 388 indicates to the user that the result is non-actionable and that the result should be confirmed. For example, a non-actionable result is a reading that is determined to be too high or too low for a therapy treatment, decision, or recommendation to be made—e.g., an insulin calculation. Screen 388 includes a trigger element for providing more information to the user regarding the non-actionable reading. When selected by the user, a Non-Actionable Message screen 396 is provided additional details, recommendations, etc., such as recommending that the user take a test strip measurement before making any treatment decisions. User confirmation (e.g., by touching the “OK” button 396a) will return the user to the previously displayed Results screen.

Results - Masked Mode

[00276] FIG. 10C illustrates an example Results - Masked screen 398, according to one embodiment. When a scan is performed while the device is set for the Masked Mode, a Results - Masked screen 398 is displayed and indicates to the user that the reading was successful. Screen 398 does not provide the resulting reading to the user. The resulting reading is stored along with resulting readings from other scans in the device. These stored readings can later be accessed by a physician or other health care professional at a later time. For example, the physician or HCP may download the data during the next patient visit (e.g., via a wired or wireless connection between the reader and the physician’s or HCP’s computer,); or the data may be transferred via the internet from the reader (or patient’s PC) to the physician’s or HCP’s computer or server; etc.

Blood Glucose Strip Test Interface

[00296] FIG. 11 illustrates an example method 440 for performing a blood glucose test with a test strip, according to one embodiment. At block 442, a test strip is inserted within an analyte monitoring device that is powered off. Once inserted into the device, the device powers on, as shown at block 444. The strip port light, such as a light emitting diode for example, turns on and provides light to the strip port, as shown at block 446. At block 448, it is determined whether a universal serial bus (USB) connection is established with the device. It should be appreciated that other communication technologies may be implemented in other embodiments—e.g., micro-USB, mini USB, RS-232, Ethernet, Firewire, or other data communication connections. If a USB connection is established, then the strip test is prevented and a Strip Test Disabled screen 450 is displayed to indicate that the strip test is not permitted and that the user should unplug the device to perform a glucose test. If the test strip or the USB connection is removed, then the Reader will display the Home screen.

[00297] If at block 448, it is determined that a USB connection is not established, then it is determined if the inserted test strip is a blood glucose test strip or a ketone test strip, as shown at block 452. The test strip may include an identifying element, such as a specific contact configuration, to enable the device to identify what type of test strip it is. If it is determined that the test strip is a ketone test strip, then the device initiates the Ketone Test interface to perform a ketone test measurement, as shown by block 454. If, on the other hand, the test strip is determined to be a blood glucose test strip, then it is determined if the device temperature is outside of the device’s operating range, as represented by block 456 and reference path F.

[00298] If it is determined that the temperature is above or below the device’s operating range, then the port light is turned off, as shown by block 458, and the Strip Test Results interface is initiated and indicates that the temperature is too high or too low, as shown by Strip Test Results screen 460 and 462, respectively.

[00299] If at block 456, it is determined that the temperature is within the device’s operating range, then Add Blood interface 464 is displayed to indicate that blood may be applied to the test strip. If the test strip is removed at this point, as shown by block 466, then the port light turns off and the Home screen is displayed, as

PCT/US2012/027022 represented by blocks 468 and 470, respectively. If at screen 464, blood is applied to the test strip, as shown by block 472, then it is determined if there was sufficient blood applied to accurately perform a test measurement, as shown by block 474. It should be appreciated that the timing of this determination may vary. If not enough blood is present, then the Strip/Hardware Errors interface is displayed to indicate that not enough blood was applied or that there was an error, as shown by block 476.

[00300] If it is determined that sufficient blood has been applied to the test strip, then the port light turns off, as shown by block 478, and a test measurement is performed. A Waiting interface 480 may be displayed while the test measurement is being performed. At block 482, it is determined if the results are ready. If ready, then the Strips Test Results screen 486 is displayed to indicate the resulting reading. If not ready (e.g., after a predetermined timeout period), then the Strip/Hardware Errors screen 484 is displayed to indicate that there was an error in the measurement.

[00301] Looking ahead to FIG. 34, an example Waiting interface according to one embodiment is illustrated. Waiting interface 2400 is animated. For example, the a first screen 2402 includes a butterfly 2401 at the bottom left corner. As the next screen 2404 is displayed, the butterfly 2401 is located in a different position. Similarly, at the next screen 2406, the butterfly 2401 is again moved to a different position. When displayed consecutively, an animated sequence results.

[00302] FIG. 34 also illustrates an example animation interface 2408 to instruct the user to add blood, according to one embodiment. Screens 2410, 2412, and 2414 display an image of a finger with blood on it and an analyte monitoring device with test strip inserted into the strip port. The finger and test strip move closer as the sequence of screens 2410, 2412, and 2414 progress to animate the application of blood process. Animation interface 2408 may be displayed, for example, when the analyte monitoring device is ready to receive blood

[00303] FIG. 34 also illustrates an example animation interface 2415 to instruct the user to add blood during a ketone test, according to one embodiment. Simiarly to animation interface 2408, screens 2416, 2418, and 2420 display an image of a finger with blood on it and an analyte monitoring device with test strip inserted into the strip port. The finger and test strip move closer as the sequence of screens 2416, 2418, and 2420 progress to animate the application of blood

Reader Temperature Warning (Too Hot / Too Cold) Screen

[00308] FIG. 12C illustrates example interfaces for indicating that the analyte monitoring device’s temperature is too high or too low, according to one embodiment. Results BG Temp High2/Low2 screen 502 is displayed to indicate to the user that the device temperature is either too high or too low to provide a reading, such as with respect to a predetermined “safe’’ range of temperatures to perform an accurate test measurement. For example, screen 502 may have a warning message and/or icon 502a indicating too high or too low of a temperature and may further indicate that a glucose reading is not available, as shown. Screen 502 provides a trigger element 502b for providing additional information regarding the too high or too low device temperature. For example, when the user touches the touch-sensitive button 502b, another screen 504 or 506 is displayed to provide additional details or information, such as that the device temperature is too low or too high, respectively, and that the user should try again later. The user can confirm by pressing the “OK” button and return to the previously displayed Results screen, for instance.

[00309] Results BG Temp High1/Low1 screen 508 is an example interface that is displayed when a test measurement is available, but also indicates to the user that the device temperature is either high or low, such as with respect to a predetermined “safe” range of temperatures. For example, screen 508 displays the resulting test measurement 508a and also displays a warning message and/or icon 502b indicating a high or low device temperature. Icon 502b also serves as a trigger element for providing additional information regarding the high or low device temperature. For example, when the user touches the touchsensitive button 502b, another screen 512 or 510 is displayed to provide additional details or information, such as that the device temperature is too low or too high, respectively, and that the user should try again later. In one embodiment, the device is programmed such that the temperature error takes precedence over other notifications that may be implemented.

PCT/US2012/027022 should be appreciated that other communication technologies may be implemented in other embodiments—e.g., micro-USB, mini USB, RS-232, Ethernet, Firewire, or other data communication connections. If a USB connection is established, then the strip test is prevented and a Strip Test Disabled screen 544 is displayed to indicate that the strip test is not permitted and that the user should unplug the device to perform a ketone or blood glucose test. If the test strip or the USB connection is removed, then the Reader will display the Home screen.

[00324] If at block 542, it is determined that a USB connection is not established, then it is determined if the inserted test strip is a blood glucose test strip or a ketone test strip, as shown at block 546. The test strip may include an identifying element, such as a specific contact configuration, to enable the device to identify what type of test strip it is. If it is determined that the test strip is a blood glucose test strip, then the device initiates the Blood Glucose Strip Test interface to perform a blood glucose test measurement, as shown by block 548. If, on the other hand, the test strip is determined to be a ketone test strip, then it is determined if the device temperature is outside of the device’s operating range, as represented by block 550 and reference path H.

[00325] If it is determined that the temperature is above or below the device’s operating range, then the port light is turned off, as shown by block 551, and the Ketone Results interface is initiated and indicates that the temperature is too high or too low, as shown by Ketone Results screen 552 and 554, respectively.

[00326] If at block 550, it is determined that the temperature is within the device’s operating range, then P K Add Blood interface 556 is displayed to indicate that blood may be applied to the test strip. If the test strip is removed at this point, as shown by block 558, then the port light turns off and the Home screen is displayed, as represented by blocks 560 and 562, respectively. If at screen 556, blood is applied to the test strip, as shown by block 564, then it is determined if there was sufficient blood applied to accurately perform a test measurement, as shown by block 566 and reference path I. It should be appreciated that the timing of this determination may vary. If not enough blood is present, then the Strip/Hardware Errors interface is displayed to indicate that not enough blood was applied or that there was an error, as shown by block 568.

The Note (Insulin Calculator Disabled) Interface 3002, shown in FIG. 15A, begins

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022 with the display of an “Add to Logbook” screen 3006. This “Add to Logbook” screen 3006 includes a list of several different notes that may be entered into the Logbook. The list of user selectable notes may include default (e.g., preset notes) and, in some instances, custom (e.g., user-defined) notes. For example, the default notes may include one or more of the following: rapid-acting insulin 3008, long-acting insulin 3010, food 3012, exercise 3014, and medication 3016. The custom notes may include any notes created by the user through the associated informatics software. In some cases, 12 notes may be included in the list of user-selectable notes. For example, 5 default notes and 7 custom notes may be included. In certain embodiments, 4 user-selectable notes are displayed on the touchscreen at once. If there are more than 4 user-selectable notes, the list of notes may be scrolled as necessary to view the list using scroll touchscreen buttons, such as down arrow (e.g., down triangle) touchscreen button 3018 and up arrow (e.g., up triangle) touchscreen button 3020. One or more user-selectable notes may be selected by touching the touchscreen checkbox adjacent the note desired to be selected. Touching a touchscreen checkbox will toggle the checkbox from a checked to unchecked state indicating whether the associated not is selected or not selected, respectively. For instance, the rapid-acting insulin note may be selected by touching the touchscreen checkbox 3022, which then displays a check mark in the touchscreen checkbox to indicate that the rapid-acting insulin note has been selected. The other user-selectable notes may be selected or unselected (e.g., checked or unchecked) as desired in an analogous manner.

[00345] The selection of notes may be saved by touching the “OK” touchscreen button 3024, which saves the selection of user-selectable notes and returns the graphical user interface to the previous screen. If the “OK” touchscreen button 3024 is pressed without changing the selection of user-selectable notes, then the previous selection of user-selectable notes is retained and saved.

[00346] In some embodiments, the amount of rapid-acting insulin, long-acting insulin, food, exercise, and medication may be entered by touching the numerical input touchscreen button (e.g., the “1 2 3” touchscreen button) associated with the desired selection. In some cases, the numerical input touchscreen button may not be displayed if the corresponding touchscreen checkbox is not checked, and may only be displayed if the corresponding

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022 touchscreen checkbox is checked. For example, when rapid-acting insulin checkbox 3008 is unchecked, the numerical input touchscreen button 3026 for rapid-acting insulin is not displayed. When the rapid-acting insulin checkbox is checked 3022, the numerical input touchscreen button 3026 for rapid-acting insulin is displayed and may be selected.

[00347] The amount of rapid-acting insulin may be entered by pressing the numerical input touchscreen button 3026 associated with the rapid-acting insulin note selection. Pressing the numerical input touchscreen button 3026 for rapidacting insulin will cause a numerical input screen 3028 for rapid acting insulin (e.g., the “Enter Rapid-Acting Insulin” screen) to be displayed, as shown by reference path (J) (see FIG. 15B). In the numerical input screen 3028 for rapidacting insulin, the amount (e.g., units) of rapid-acting insulin may be entered. The numerical input screen initially displays no value (e.g., is displayed in place of any numbers), however, the amount of rapid-acting insulin may be adjusted by pressing the up arrow 3030 (e.g., “+”) touchscreen button or the down arrow 3032 (e.g., “-”) touchscreen button to increase or decrease, respectively, the amount of rapid-acting insulin as desired. For example, the amount of rapid-acting insulin 3034 may be adjusted by 1 unit increments by tapping the up arrow 3030 or the down arrow 3032. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. Once the desired amount of rapid-acting insulin is entered, the amount may be saved by pressing the “OK” touchscreen button 3036, which saves the entered amount of rapid-acting insulin and then returns the graphical user interface to the “Add to Logbook” screen 3006, as shown by reference path (J). Numerical values for long-acting insulin may be entered in an analogous manner by pressing the numerical input touchscreen button 3038 (e.g., the “1 2 3” touchscreen button) associated with the long-acting insulin selection on the “Add to Logbook” screen 3006.

[00348] Numerical values for food may be entered by pressing the numerical input touchscreen button 3040 (e.g., the “1 2 3” touchscreen button) associated with the food selection on the “Add to Logbook” screen 3006.

PCT/US2012/027022 reference path (J) (see FIG. 15C). In the numerical input screen 3042 for food, the amount (e.g., grams) of carbs may be entered. The numerical input screen initially displays no value (e.g., is displayed in place of any numbers), however, the amount of carbs may be adjusted by pressing the up arrow 3044 (e.g., “+”) touchscreen button or the down arrow 3046 (e.g., “-”) touchscreen button to increase or decrease, respectively, the amount of carbs as desired. For example, the amount of carbs 3048 may be adjusted by 1 gram increments by tapping the up arrow 3044 or the down arrow 3046. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. Once the desired amount of carbs is entered, the amount may be saved by pressing the “OK” touchscreen button 3050, which saves the entered amount of carbs and then returns the graphical user interface to the “Add to Logbook” screen 3006, as shown by reference path (J).

[00349] In certain embodiments, instead of entering the amount of food as grams of carbs, the amount of food may be entered as servings of carbs, as shown in FIG. 15E. In the numerical input screen 3068 for servings of carbs, the screen initially displays no value (e.g., “- is displayed in place of any numbers), however, the servings of carbs may be adjusted by pressing the up arrow 3070 (e.g., “+”) touchscreen button or the down arrow 3072 (e.g., “-”) touchscreen button to increase or decrease, respectively, the servings of carbs as desired. For example, the servings of carbs 3074 may be adjusted by 0.5 serving increments by tapping the up arrow 3070 or the down arrow 3072. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. In some cases, the numerical input screen 3068 for servings of carbs may include a display of the grams of carbs 3076 that corresponds to the number of servings entered. In some cases, the numerical input screen 3068 for servings of carbs may include a display of the energy (e.g., kcal) of carbs 3078 that corresponds to the number of servings entered. Once the desired servings of carbs is entered, the value may be saved by pressing the “OK” touchscreen button 3080, which saves the entered servings of carbs and then returns the graphical user interface to the “Add to Logbook” screen 3006.

For example, the numerical input screen 3042 includes a “1 hr” touchscreen checkbox 3052 and a “2 hr” touchscreen checkbox 3054. None, one or both of the touchscreen checkboxes may be selected as desired. Pressing the “1 hr” touchscreen checkbox 3052 will display a check mark in the “1 hr” touchscreen checkbox 3052 indicating that the “1 hr” touchscreen checkbox 3052 has been selected and will set the Reader to alert the user to check the user’s glucose level after 1 hour. Pressing the “2 hr” touchscreen checkbox 3054 will display a check mark in the “2 hr” touchscreen checkbox 3054 indicating that the “2 hr” touchscreen checkbox 3054 has been selected and will set the Reader to alert the user to check the user’s glucose level after 2 hours. The check glucose reminder checkboxes may also be displayed on the numerical input screen 3068 for entering the servings of carbs as described above (see FIG. 15E).

[00351] As indicated above, a second notes interface may be provided for embodiments where the insulin calculator is enabled 3004. The Note (Insulin Calculator Enabled) Interface 3004, shown in FIG. 15D, begins with the display of an “Add to Logbook” screen 3056. This “Add to Logbook” screen 3056 includes a list of several different notes that may be entered into the Logbook, similar to the “Add to Logbook” screen 3006 in the Note (Insulin Calculator Disabled) Interface 3002 described above. In the “Add to Logbook” screen 3056 of the Note (Insulin Calculator Enabled) Interface 3004, the user-selectable notes (e.g., default and custom notes) may be selected (e.g., checked) or unselected (e.g., unchecked) as desired in an analogous manner as described above in relation to the Note (Insulin Calculator Disabled) Interface 3002. In addition, the numerical input touchscreen buttons (e.g., the “1 2 3” touchscreen buttons) of the Note (Insulin Calculator Enabled) Interface 3004 function in an analogous manner as described above in relation to the Note (Insulin Calculator Disabled) Interface 3002.

[00352] In the Note (Insulin Calculator Enabled) Interface 3004, the insulin on board and rapid-acting insulin calculator features of the graphical user interface are enabled. For instance, in the Note (Insulin Calculator Enabled) Interface

PCT/US2012/027022

3004, rather than displaying a numerical input touchscreen button for rapidacting insulin, a calculator touchscreen button 3058 is displayed with the rapidacting insulin selection. Pressing the calculator touchscreen button 3058 will cause the graphical user interface to display the Insulin on Board Interface 3060 (see FIG.16) and the Insulin Calculator Interface 3062 (see FIG. 17). In some embodiments, if food information (e.g., amount of carbs) is entered as described above, then when the calculator touchscreen button 3058 is pressed, the amount of carbs that was previously entered will automatically be displayed in the corresponding insulin on board and calculator interface screens.

[00353] In certain embodiments, the Notes - From Logbook Entry Interface 3064 may be displayed from the Logbook Entry screen if the “add or edit notes” touchscreen button is pressed. The Notes - From Logbook Entry Interface 3064 begins with the display of an “Add to Logbook” screen 3066. This “Add to Logbook” screen 3066 includes a list of several different user-selectable notes that may be entered into the Logbook, similar to user-selectable notes described above. In certain embodiments, the “Add to Logbook” screen 3066 of the Notes - From Logbook Entry Interface 3064 does not include a user-selectable note for rapid-acting insulin or food. The other default notes (e.g., long-acting insulin, exercise, medication) and custom notes may still be available for selection by the user as desired.

Insulin on Board Interface

[00354] As described above, pressing the calculator touchscreen button 3058 from the “Add to Logbook” screen 3056 of the Notes (Insulin Calculator Enabled) Interface 3004, will cause the graphical user interface to display the Insulin on Board Interface 3060 (see FIG.16). Regarding FIG. 16A, in certain embodiments, a user’s insulin on board (IOB) information is used in the calculation of a recommended rapid-acting insulin dosage amount. For example, if an insulin dosage has been logged (e.g., logged as a calculated dose, or entered into the logbook as a rapid-acting dose), then the insulin dosage information may be used in the calculation of a recommended rapid-acting insulin dosage amount 3082.

[00355] In certain embodiments, a user’s insulin on board information is used in the calculation of a recommended rapid-acting insulin dosage amount if the user’s most recent insulin dose was administered within a certain time period. In

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022 some instances, the insulin calculator may be partially locked out if the difference between the current time and the time the most recent rapid-acting insulin was administered is less than a lock out time period (e.g., the most recent insulin dose was administered within a preceding lockout time period, such as within the past 2 hours). During the lockout time period, the insulin calculator may be programmed to only calculate a meal bolus and may not calculate an additional correction bolus 3084. During the lockout time period, the insulin calculator may not include insulin on board into the calculation of a meal bolus.

[00356] If the difference between the current time and the time the most recent insulin bolus was administered is greater than a threshold time period (e.g., the lockout time period) and less than the duration of insulin action, then the insulin calculator may be programmed to include the user’s IOB into the calculation of the recommended rapid-acting insulin dosage amount 3086. In the time period between the end of the lockout time period and the end of the user’s duration of insulin action, the insulin calculator may be programmed to determine the recommended rapid-acting insulin dosage amount based on the determined analyte concentration and the insulin on board information. For instance, in the time period between the end of the lockout time period and the end of the user’s duration of insulin action, the insulin calculator may be programmed to subtract the user’s IOB from the rapid-acting insulin dosage based upon the current glucose concentration level to determine the recommended rapid-acting insulin dosage amount.

[00357] In certain instances, if the difference between the current time and the time the most recent insulin bolus was administered is greater than the user’s duration of insulin action, then the insulin calculator will not include insulin on board into the calculation of a recommended rapid-acting insulin dosage amount 3088. In the time period after the user’s duration of insulin action has expired (and before the next dose of insulin is administered), the insulin calculator may assume the user’s insulin on board is zero. In the time period after the user’s duration of insulin action has expired (and before the next dose of insulin is administered), the insulin calculator may be programmed to determine the rapidacting insulin dosage amount based on the determined glucose concentration (without including the insulin on board information).

[00358] Regarding FIG. 16B, the Insulin on Board Interface is shown, and begins with a prompt screen 3090 prompting the user with a question asking if the user has forgotten to log any rapid-acting insulin the user has taken since a prior predetermined time point. The prior predetermined time point corresponds to the most recent of either: (a) the current time minus the set insulin duration of action, or (b) the time of the last logged dose of rapid-acting insulin. The prompt screen 3090 has a “Yes” touchscreen button 3092 and a “No” touchscreen button 3094 to select a yes or no answer to the prompted question. If the “No” touchscreen button 3094 is pressed, then the graphical user interface displays the Insulin Calculator Interface 3062 (see FIG. 17). If the “Yes” touchscreen button is pressed, then the graphical user interface displays a numerical input screen 3096 in the Insulin on Board Interface. On the numerical input screen 3096, the amount of rapid-acting insulin that the user has forgotten to log since the prior predetermined time point may be entered. The amount (e.g., units) of rapidacting insulin may be adjusted by pressing the up arrow 3098 (e.g., “+”) touchscreen button or the down arrow 3100 (e.g., “-”) touchscreen button to increase or decrease, respectively, the amount of rapid acting insulin as desired. For example, the amount of rapid acting insulin 3102 may be adjusted by 1 unit increments by tapping the up arrow 3098 or the down arrow 3100. In some embodiments, the amount of rapid-acting insulin may be adjusted by 0.5 unit increments (not shown) if the calculator is set to allow half-unit increments. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. Numerical input screen may also include a “?” touchscreen button 3104, which, when pressed, provides a help screen 3106 that includes additional instructions to the user. For example, the help screen 3106 may instruct the user to enter the sum total of insulin units that the user has taken over the last X hours that the user has not already logged, where X is the insulin duration of action time. The help screen 3106 may also inform the user that the Reader will use the entered amount of rapid-acting insulin to calculate the user’s next rapid-acting insulin dose. The help screen 3106 includes an “OK” touchscreen button 3108, which, when pressed, returns the display to the numerical input screen 3096.

[00359] On the numerical input screen 3096, once the desired amount of rapidacting insulin has been entered, the “Next” touchscreen button 3110 may be pressed to advance the graphical user interface to a time input screen 3114, as shown by reference path (M) (see FIG. 16C). Alternatively, on the numerical input screen 3096, the “Back” touchscreen button 3112 may be pressed, which returns the graphical user interface to the prompt screen 3090.

[00360] Regarding FIG. 16C, on the time input screen 3114, the display presents a question asking the user how long ago was the unlogged dose of rapid-acting insulin. On the time input screen 3114, the time since the last unlogged rapidacting insulin dose may be adjusted by pressing the up arrow 3116 (e.g., “+”) touchscreen button or the down arrow 3118 (e.g., “-”) touchscreen button to increase or decrease, respectively, the time as desired. For example, the time 3120 may be adjusted by 15 minute increments by tapping the up arrow 3116 or the down arrow 3118. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. In some instances, the default time is 15 minutes (e.g., displayed as “15 minutes or less”). In some cases, the maximum time is the time value set for the insulin duration of action. If the user presses the up arrow 3116 once while the time is at the maximum value, then the time displayed may be shown as “[insulin duration] hours or more”, and the up arrow 3116 may be displayed as greyed out and may be un-selectable by the user.

[00361] The time input screen 3114 also includes a “?” touchscreen button 3122, which, when pressed, provides a help screen 3106 that includes additional instructions to the user as described above and as indicated by reference path (K). The time input screen includes a “Back” touchscreen button 3124, which, when pressed, returns the display to the numerical input screen 3096 as shown by reference path (L). Once the desired time since the last unlogged rapid-acting insulin dose has been entered on the time input screen 3114, the “Next” touchscreen button 3126 may be pressed to advance the graphical user interface to the next screen in the Insulin on Board Interface, such as screen 3128. Pressing the “Next” touchscreen button will save the entered rapid-acting insulin dose with a time stamp reflecting the time calculated based on the interval since the dose was taken as indicated by the user in the previous time

PCT/US2012/027022 input screen 3114. Screen 3128 informs the user that the entered dose of rapidacting insulin will be used in the calculation of the user’s suggested insulin dose, and that the next screen will allow the user to enter what the user plans to eat. Screen 3128 includes a “Back” touchscreen button 3130, which, when pressed, returns the display to the time input screen 3114. Screen 3128 includes a “Next” touchscreen button 3132, which, when pressed, causes the graphical user interface to display the Insulin Calculator Interface 3062 (see FIG. 17).

Insulin Calculator Interface

[00362] An Insulin Calculator Interface 3062 begins with the display of an “Enter Carbs” screen (see FIG. 17B). On the “Enter Carbs” screen, the amount of carbs may be entered. The amount of carbs may be entered as grams, servings, or by meal, depending on the settings of the Reader.

[00363] For example, the amount of carbs may be entered as grams of carbs on the “Enter Carbs” (grams) screen 3200. The “Enter Carbs” (grams) screen 3200 initially displays no value (e.g., or “0” is displayed), however, the grams of carbs may be adjusted by pressing the up arrow 3202 (e.g., “+”) touchscreen button or the down arrow 3204 (e.g., “-”) touchscreen button to increase or decrease, respectively, the grams of carbs as desired, as shown by reference path (T) (see FIG. 17C). For example, the grams of carbs 3206 may be adjusted by 1 gram increments by tapping the up arrow 3202 or the down arrow 3204. In some cases, the minimum grams of carbs that may be entered is zero carbs, and the maximum grams of carbs that may be entered is 200 grams of carbs. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. Once the desired amount is entered, the amount may be saved by pressing the “Done” touchscreen button 3208, which saves the entered grams of carbs and then advances the graphical user interface to the Insulin Calculation Interface 3212, as shown by reference paths (S and V) (see FIGS. 17B, 17C and 17E). The “Enter Carbs” (grams) screen 3200 includes a “Back” touchscreen button 3210, which, when pressed, returns the display to the Results screen.

[00364] In certain embodiments, the amount of carbs may be entered as servings of carbs on the “Enter Carbs” (servings) screen 3216. The “Enter Carbs” (servings) screen 3216 initially displays no value (e.g., or “0” or “0.0” is

PCT/US2012/027022 displayed), however, the servings of carbs may be adjusted by pressing the up arrow 3218 (e.g., “+”) touchscreen button or the down arrow 3220 (e.g., “-”) touchscreen button to increase or decrease, respectively, the servings of carbs as desired, as shown by reference path (T) (see FIG. 17C). For example, the servings of carbs 3222 may be adjusted by 0.5 serving increments by tapping the up arrow 3218 or the down arrow 3220. In some cases, the minimum servings of carbs that may be entered is zero servings. In some instances, the serving size may be set to 10 or 12 grams of carbs per serving and the maximum servings of carbs that may be entered is 20 servings. In some instances, the serving size may be set to 15 grams of carbs per serving and the maximum servings of carbs that may be entered is 15 servings. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. In some cases, the “Enter Garbs” (servings) screen 3216 may include a display of the grams of carbs 3228 that corresponds to the number of servings entered (see FIG. 17C). In some cases, the “Enter Carbs” (servings) screen 3216 may include a display of the energy (e.g., kcal) of carbs 3230 that corresponds to the number of servings entered (see FIG. 17C). Once the desired amount is entered, the amount may be saved by pressing the “Done” touchscreen button 3224, which saves the entered servings of carbs and then advances the graphical user interface to the Insulin Calculation Interface 3212, as shown by reference paths (S and V) (see FIGS. 17B, 17C and 17E). The “Enter Carbs” (servings) screen 3216 includes a “Back” touchscreen button 3226, which, when pressed, returns the display to the Results screen.

[00365] In certain embodiments, the amount of carbs may be entered by meal on the “Enter Carbs” (meal) screen 3232. The “Enter Carbs” (meal) screen 3232 displays a list of meals, such as breakfast, lunch, dinner, or no meal. Each selection includes a corresponding touchscreen radio button. For example, to select the “Dinner” meal, the touchscreen radio button 3234 associated with the “Dinner” selection may be pressed. The “Enter Carbs” (meal) screen 3232 includes a “Back” touchscreen button 3238, which, when pressed, returns the display to the Results screen. The “Enter Carbs” (meal) screen 3232 includes a “Next” touchscreen button 3236, which, when pressed, may advance the

[00366] The “Double Check” screen 3240 (see FIG. 17C) is displayed if the user has marked the same meal since midnight (12:00AM) of the current day. The “Double Check” screen 3240 displays a warning to the user indicating that the user has already logged insulin for the selected meal that day, and asks the user if the user wants to log more insulin for the same meal that day. The “Double Check” screen 3240 includes a “No” touchscreen button, which, when pressed, returns the graphical user interface to the “Enter Carbs” (meal) screen 3232 via reference path (A1). The “Double Check” screen 3240 includes a “Yes” touchscreen button, which, when pressed, advances the graphical user interface to the Insulin Calculation Interface 3212 via reference path (Q) (see FIG. 17E).

[00367] Referring again to FIG. 17B, the “Enter “Carbs” screens (e.g., the “Enter Carbs” (grams) screen 3200, and the “Enter Carbs” (servings) screen 3216) both include a “?” touchscreen button 3214, which, when pressed, causes the graphical user interface to display help screens 3246, as shown by reference path (Ο) in FIG. 17B, or by reference path (N) in FIG. 17C. Help screens 3246 (see FIG. 17A) may display information to the user depending on whether the Reader is set to display carbs as grams, servings by grams of carbs, or servings by kcal of carbs. For example, a help screen 3248 may be shown that displays a set of help information to the user regarding carbohydrates when the Reader is set to display carbs as grams. In other instances, the help screen 3250 may be shown that displays a different set of help information to the user regarding carbohydrates as servings by grams of carbs when the Reader is set to display servings by grams of carbs. In other instances, the help screen 3252 may be shown that displays yet a different set of help information to the user regarding carbohydrates as servings by kcal of carbs when the Reader is set to display servings by kcal of carbs. In certain instances, if the help information includes more text than is able to be displayed on a single help screen, the help screen may include a down arrow 3254, which, when pressed, causes the graphical user interface to display the remaining text on a second help screen 3256. The second help screen 3256 includes an up arrow 3258, which, when pressed, returns the graphical user interface to the first help screen 3248, 3250 or 3252 depending on the settings of the Reader as described above. The help screens

3248, 3250, 3252 and 3256 include an “OK” touchscreen button 3260, which, when pressed, returns the graphical user interface to the “Enter “Carbs” screen (e.g., the “Enter Carbs” (grams) screen 3200, or the “Enter Carbs” (servings) screen 3216) from which the help screen was launched, via reference path (P).

[00368] Referring to FIG. 17B, once the desired amount of carbs is entered, the amount may be saved by pressing the “Done” touchscreen button 3208 or 3224, which saves the entered amount of carbs (e.g., grams of carbs or servings of carbs) and then advances the graphical user interface to the appropriate Insulin Calculation Interface 3212, as shown by reference path (S) (see FIG. 17E). The Insulin Calculation Interface 3212 displays the suggested dose of insulin based on the amount of carbs entered by the user on the previous screens as described above and/or the user’s insulin on board, if any, as described above. The Insulin Calculation Interface 3212 may vary in appearance depending on whether the Reader is set to display whole units of insulin, half units of insulin, or a decimal point or a comma between the whole and half units of insulin.

[00369] Referring to FIG. 17E, in embodiments of the Insulin Calculation Interface 3212 where the Reader is set to display whole units of insulin, the Insulin Calculation Interface 3212 will appear as Suggested Dose screen 3262. Suggested Dose screen 3262 displays the suggested dose of insulin 3264 as units of insulin. The suggested dose of insulin may be adjusted in 1 insulin unit increments by pressing the up arrow 3266 (e.g., “+”) touchscreen button or the down arrow 3268 (e.g., “-”) touchscreen button to increase or decrease, respectively, the suggested dose of insulin as desired. The minimum and maximum values for the suggested dose of insulin are 0 and 99, respectively. If the suggested dose of insulin is adjusted by the user from its initial value, the amount of units increased or decreased by the user 3270 will be shown below the suggested insulin dose 3264. If the user adjustment of the suggested dose of insulin is calculated to reduce the user’s blood glucose below the target range, then the graphical user interface will display a warning screen 3292 that displays a caution to the user that the insulin dose entered may take the user’s blood glucose lower than the user’s target range and put the user at risk for a low glucose event (see FIG. 17D). The warning screen 3292 includes an “OK” touchscreen button, which, when pressed, returns the graphical user interface to the Suggested Dose screen 3262 via reference path (W). The Suggested Dose

[00371] Referring to FIG. 17E, in embodiments of the Insulin Calculation Interface 3212 where the Reader is set to display half unit increments of insulin and a comma between the whole and half units, the Insulin Calculation Interface 3212 will appear as Suggested Dose screen 3290. The functions of Suggested Dose screen 3290 are analogous to those described for Suggested Dose screen 3276 above.

[00372] If the insulin calculator of the Reader determines that no insulin dose is suggested, then the Insulin Calculation Interface 3212 will be displayed as No Suggested Dose screen 3298, which displays information indicating that based on the user’s current glucose level, no rapid-acting insulin is being suggested. The No Suggested Dose screen includes a “Back” touchscreen button 3300, which, when pressed, returns the user to the prior “Enter “Carbs” screen (e.g., the “Enter Carbs” (grams) screen 3200, or the “Enter Carbs” (servings) screen 3216) via reference path (R). The No Suggested Dose screen 3298 includes a “Next” touchscreen button 3302, which, when pressed, advances the graphical user interface to Suggested Dose screen 3304. Suggested Dose screen 3304 begins by displaying a suggested does of insulin 3306 as 0 units of insulin. The suggested dose of insulin may be adjusted in 1 unit or 0.5 insulin unit increments, depending on the Reader settings, by pressing the up arrow 3308 (e.g., “+”) touchscreen button or the down arrow 3310 (e.g., “-”) touchscreen button to increase or decrease, respectively, the suggested dose of insulin as desired. If the suggested dose of insulin is adjusted by the user from its initial value, the amount of units increased or decreased by the user will be shown below the suggested insulin dose 3306. If the user adjustment of the suggested dose of insulin is calculated to reduce the user’s blood glucose below the target range, then the graphical user interface will display a warning screen 3292 that displays a caution to the user that the insulin dose entered may take the user’s blood glucose lower than the user’s target range and put the user at risk for a low glucose event (see FIG. 17D). The warning screen 3292 includes an “OK” touchscreen button, which, when pressed, returns the graphical user interface to

PCT/US2012/027022 the Suggested Dose screen 3304 via reference path (W). The Suggested Dose screen 3304 includes a “Back” touchscreen button 3312, which, when pressed, returns the user to the prior No Suggested Dose screen 3298. The Suggested Dose screen 3304 also includes a “Log dose” touchscreen button 3314, which, when pressed, saves the suggested insulin dose in the logbook along with an associated glucose test result and the time the test was taken (e.g., the insulin dose is not saved as delivered at the time the “Log dose” touchscreen button is pressed) and advances the graphical user interface to the Logbook via reference path (Y) (see FIG. 17D).

[00373] Suggested Dose screens 3262, 3276, 3290 and 3304 include a “Dose details” touchscreen button 3294 (e.g., an “i touchscreen button), which, when pressed, causes graphical user interface to display Dose Details Interface via reference path (X) (see FIG. 17D).

[00374] Dose Details Interface 3296 is shown in FIGS. 18A and 18B. Dose Details Interface begins a Dose Details screen (e.g., 3316, 3318 and 3320) that displays a summary of the calculated insulin dose. The Dose Details screen (e.g., 3316, 3318 and 3320) may have various appearances depending on the settings of the Reader (e.g., whether the Reader is set to display carbs as grams of carbs, servings of carbs, or by meal) and the data input by the user or calculated by the Reader (e.g., amount of carbs, insulin on board, user adjustment to the suggested dose of insulin, etc.). The Dose Details screen displays the amount of carbs by meal 3322, as grams of carbs 3324, or as servings of carbs 3326. If insulin correction is enabled on the Reader, the Dose Details screen will display the suggested insulin dose 3328. If insulin correction is disabled on the Reader (e.g., the Easy setup sets “no correction insulin”) then the suggested insulin dose is not displayed. If the Reader determines that insulin on board is present, then the Dose Details screen displays the amount of insulin on board 3330. In the Reader determines that no insulin on board is present, then the amount of insulin on board is not displayed. If the user adjusted the suggested insulin dose, the Dose Details screen will display the amount the user adjusted the suggested insulin dose 3332. Based on the above data, the Dose Details screen displays the calculated insulin dose 3334.

[00375] The Dose Details screen includes a down arrow touchscreen button 3336, which, when pressed, advances the Dose Details screen to the second page of

PCT/US2012/027022 the Dose Details screen via reference path (B1) (see FIG. 18B). The information displayed on the second page of the Dose Details screen may vary depending on whether insulin on board is present and whether the suggested dose of insulin only accounts for carbs in the user’s meal. If insulin on board is not present, then the second page of the Dose Details screen 3338 displays information indicating that the suggested dose of rapid-acting insulin covers the carbs in the user’s meal and corrects for the user’s current glucose level. If insulin on board is present and the user has taken insulin within the past 2 hours, then the second Dose Details screen 3340 displays information indicating that the user has taken rapid-acting insulin in the past 2 hours, and the suggested dose of insulin covers the carbs in the user’s meal but does not correct for the user's current glucose level. If insulin on board is present and the time when the user has last taken insulin is more than 2 hours from the current time but less than the duration of insulin action, then the second Dose Details screen 3342 displays information indicating that the user has taken rapid-acting insulin in the past 4 hours, and the suggested dose of insulin covers the carbs in the user’s meal, corrects for the user’s current glucose level, and accounts for insulin that was previously logged. The second Dose Details screen (e.g., 3338. 3340 and 3342) include an up arrow touchscreen button 3344, which, when pressed, returns the graphical user interface to the previous Dose Details screen.

Receive Reminders Interface

[00385] An exemplary embodiment of a graphical user interface which may be utilized in connection with a Reader as described herein and which facilitates a Receive Reminder procedure 3500 for receiving reminders is provided. This graphical user interface is now described in greater detail with reference to FIG. 20.

[00386] The Receive Reminder Interface 3500, shown in FIG. 20B, begins when a reminder (e.g., a reminder that has been set using the Reminders Interface 3400 described above) is activated, such as when the time or triggering event of a scheduled reminder is reached. A scheduled reminder should be displayed when

Date Reçue/Date Received 2021-04-20

WO 2012/154286

PCT/US2012/027022 the time / triggering event of the reminder is reached even if the Reader display is off. In certain embodiments, a scheduled reminder is not displayed on the Reader if the time / triggering event of the reminder is reached: (1 ) During a blood glucose test using a strip - instead the reminder is presented after the results have been displayed; (2) When the battery is critically low - instead the reminder is presented when the battery is sufficiently charged, and the Reader is powered on; (3) During error conditions - instead the reminder is presented the next time the Reader is powered on; or (4) When the Reader is connected to a computer and data transfer is in process - instead the reminder is presented when the data transfer is completed.

[00387] When the time / triggering event of the reminder is reached, a Reminder screen is 3502 displayed (FIG. 20B). The Reminder screen 3502 includes display of the reminder with a reminder icon 3504 representing the type of reminder. For example, the reminder icon may be an “Alarm” reminder icon 3504 (e.g., a picture of a bell or alarm clock, etc.), indicating that the type of reminder is an alarm. In some instances, the reminder icon is a “Take Insulin” reminder icon 3506 (e.g., a picture of a syringe) (see FIG. 20A), indicating that the type of reminder is a reminder to the user to take insulin. In some instances, the reminder icon is a “Check Glucose” reminder icon 3508 (e.g., a picture of a glucose Reader) (see FIG. 20A), indicating that the type of reminder is a reminder to the user to check their glucose level. Other types of icons and reminders are possible.

[00388] If the Reminder sound is set to on, a beep sounds with appearance of any reminders screen. If a reminder is ignored, the reminder will appear on the screen with the next power on (whether by hardware button or strip insertion). If multiple reminders are active, the reminder screens will stack up with the most recent reminder showing first. The reminder screens will require dismissal one by one. If daily repeated reminders have been missed, once a new day’s reminder is current, the previous day’s reminder for that time is no longer active and is not part of the stack-up of reminder screens.

[00389] The Reminder screen 3502 includes a “Snooze 15 min” touchscreen button 3510, which, when pressed, sets the active reminder to re-active in 15 minutes, and returns the graphical user interface to the next active reminder or, if there are no other active reminders, to the previously displayed screen before

PCT/US2012/027022 the reminder was activated. The Reminder screen 3502 also includes an “OK” touchscreen button 3512, which, when pressed cancels the active reminder and returns the graphical user interface to the next active reminder or, if there are no other active reminders, returns the graphical user interface to the Home Screen. In the Reader powers off automatically due to a timeout while displaying the Reminder screen, the reminder that was active when the Reader timed-out will be displayed again the next time the Reader is powered on.

Reader Summaries

[00390] In some aspects of the present disclosure, the analyte monitoring device may be programmed with software to provide summaries of information and data related to obtain readings. The software provides an interface to view and manage features related to generated reports. Different types of summaries may be generated. For example, FIGS. 21A-D illustrate various types of interfaces for displaying summaries on the analyte monitoring device, according to certain embodiments. It should be appreciated that the summary screens illustrated are exemplary and should not be interpreted as limiting.

[00391] An exemplary embodiment of a graphical user interface which may be utilized in connection with a reader as described herein and which functions to provide the user with summaries of information and data related to obtained readings.

Summaries Menu Interface

[00392] FIG. 21A illustrates an exemplary interface for providing a summaries menu on the analyte monitoring device. History Menu01 screen 622 is shown in FIG. 21A and provides a menu of summary options that the user can select. Option 622a takes the user to a Logbook screen for viewing logged data, as shown by block 626. Option 622b takes the user to a Daily Graph screen which provides a summary of data in a daily graph format. Option 622c provides a screen for averages for glucose readings obtained for a period of time. If more options are available that can fit on a single screen shot, then a trigger element 622h (e.g., an arrow symbol) for scrolling or otherwise viewing the remaining options may be selected. When arrow 622h is selected, the user is taken to screen 624 wherein the remaining options are displayed. For example, option 624 provides a summary screen of low glucose events for a period of time. Option 622d provides a screen showing a summary of time that obtained

WO 2012/154286

PCT/US2012/027022 readings were in the target zone. Option 622f provides a screen showing summarizing information related to the user of the reader device. Option 622g provides a summary screen of daily patterns that have been determined or identified based on reading acquired for a period of time. Trigger element 622i takes the user back to screen 622.

[00393] When one of the options are selected, it is determined if sensor data is present, as shown at block 628. If no data is present, a No Sensor Data screen 630 is displayed to indicate to the user that no sensor data is available for the summary. In one embodiment, the all summaries except for logbook include sensor data only (e.g., glucose data obtained from the sensor). If the device includes only strip data and insufficient sensor data, then the No Sensor Data screen is still provided when a summary option is selected.

[00394] If sensor data is provided, then the corresponding screen for the selected summary option is displayed, as represented by reference path T1. From the selected summary screen, the user can navigate back to the menu options screens 622,624 to select another menu option if desired, as shown by reference path S1.

[00395] FIG. 21B illustrates a Daily Graph screen 632 for showing a daily graph 632a of sensor readings obtained over a single day or 24 hour time period. For example, graph 632a illustrates the readings obtained on Wednesday, February 22. The horizontal axis of graph 632a represents time throughout the day, while the vertical axis represents sensor reading values. A target zone 632d may also be provided on graph 632 to represent the target zone for readings. Also shown, are event indicators 632b which indicate various events with symbols or icons on the graph 632a. For example, the needle icon represents a logged insulin event indicating that an insulin dose was taken, and the apple icon represents a logged food event indicating that food was eaten. More details may be stored or logged for the given event, and in one embodiment, the event indicators 632b may be selected by the user to provide additional details regarding the event.

[00396] In the embodiment shown, trigger elements 632c (e.g., left and right arrows) are also provided to enable the user to navigate forwards and backwards to another day or 24-hour time period. For example, the user could navigate to the next day after Wednesday using the right arrow, or go to the previous day by selecting the left arrow.

[00397] FIG. 21C illustrates an exemplary Average Glucose Summary interface for providing a graph of sensor readings obtained over a time period that is summarized with respect to a predetermined time period such as single day or 24 hour time period as shown. For example, Average Glucose (GLUG) 01 screen provides a bar graph 634a for sensor readings taken over the last 7 days. The bar graph 634a includes bars for various increments of time throughout a single day. Each bar represents the average glucose reading that was obtained at that increment of time of day for the last 7 days. For example, the average of all the sensor readings obtained between 12am and 6am over the last 7 days, is 121 mg/dL. For 6am to 12, the average glucose reading was 152 mg/dL, etc.

[00398] Screen 634 also includes an average glucose value 634b for the time period of data. For example, the average glucose reading for all readings obtained over the last 7 days was 119 mg/dL. Screen 634 also includes a trigger element 634c (e.g., an arrow icon) for changing the different time period of obtained data. For example, if the user selects the right arrow icon 634c, the user is taken to AVG GLUC02 screen 636, which similarly displays a bar graph 636a and average glucose value 636b, but for a different time period, such as the last 14 days as shown. Similarly, screen 636 also includes trigger elements 634c for again increasing the time period. In this way, the user can change to AVG GLUG03 screen 638, which similarly displays a bar graph 638a and average glucose value 638b, but for a different time period, such as the last 30 days as shown. Similarly, the user can change to AVG GLUC04 screen 640, which similarly displays a bar graph 640a and average glucose value 640b, but for a different time period, such as the last 90 days as shown. Trigger elements 634c enable the user to navigate forwards and backwards between screens 634,636,638,640 to change the time periods as desired. From any of the screens, user confirmation (e.g., by selecting the “ok” button) will take the user back to the options menu interface 622,624.

[00399] FIG. 21D illustrates an exemplary screen for showing the percentage of time the sensor readings were within a target zone. Time In Target screen 642 displays a representation 642a of the percentage of time within a target zone, above a target zone, and below a target zone, for sensor readings obtained for a period of time (e.g., 7 days in the embodiment shown). Trigger element 642c is provided to enable the user to change the time period—e.g., similarly as

Date Reçue/Date Received 2021-04-20

PCT/US2012/027022 described in FIG. 21c. Representation 642a also includes bar graphs for the associated percentages.

Summaries Menu - Masked Mode Interface

[00400] FIG. 21E illustrates an exemplary screen 644 for showing a graph 644a of the number of events associated with sensor readings obtained over a time period, wherein the events are summarized with respect to a predetermined time period, such as single day or 24 hour time period as shown. For example, screen 644 indicates a graph 644a for sensor readings obtained over the last 7 days, wherein 1 event occurred between 12am and 6am, 0 events occurred between 6am and 12pm, 3 events between 12pm and 6am, etc. In the embodiment shown, the event corresponds to a low glucose reading—e.g., with respect to a target zone. Other events may also be implemented—e.g., high glucose readings, insulin dosages, food intake events, etc. Trigger element 644c is provided to enable the user to change the time period.

[00401] FIG. 21F illustrates an exemplary screen 648 for indicating information associated with the use of the sensor over a time period. For example, screen 648 indicates the average scans per day, and the number of days with sensor data, for sensor readings obtained over the last 7 days. Similarly, trigger element 648c is provided to enable the user to change the time period.

[00402] FIG. 21G illustrates an example interface for providing a summaries menu on the analyte monitoring device, when the device is in masked mode. History Menu Masked screen 620 is shown provides a menu of summary options that the user can select. Option 620a takes the user to a Logbook screen for viewing logged data. Option 620b provides a screen showing summarizing information related to the use of the reader device. Since the device is in masked mode and does not permit the user from viewing sensor readings, summary screens related to obtained readings are also not available.

WO 2012/154286

PCT/US2012/027022 that includes basic features for determining a recommended medication dosage amount, such as a recommended insulin dosage amount. For example, an easy bolus calculator may include algorithms configured to determine a recommended medication dosage amount based on a fixed medication dosage amount. In these instances, the easy bolus calculator may be appropriate for a user that administers a fixed medication dosage amount (e.g., a fixed insulin dosage amount) for each meal. In some embodiments, the easy bolus calculator only takes into account the fixed medication dosage amount when recommending the medication dosage amount to the user, and thus functions as a reminder and/or log for the fixed medication dosage amount.

[00514] The insulin calculator setup procedure begins on the Insulin Calculator Interface Setup screen 3800, where the user can select an Insulin Calculator On/Off toggle button 3802 to turn the insulin calculator on or off. When the Insulin Calculator On/Off toggle button is selected into the On” position, the insulin calculator is activated and may be set up as described below. The desired type of insulin calculator (e.g., easy or advanced calculator) can be selected by selecting the insulin calculator selection box 3804, which allows the selection of “Easy” to activate the easy insulin calculator, and “Advanced” to activate the advanced insulin calculator.

[00515] If the user selects the “Easy” selection in the insulin calculator selection box 3804, the Insulin Calculator Setup Interface screen 3800 displays the set up options for the easy bolus calculator. Set up for the easy bolus calculator is shown in FIG. 43.

[00516] In certain embodiments, the easy bolus calculator may determine a recommended medication dosage amount (e.g., a recommended rapid-acting insulin dosage amount) based on information, such as, but not limited to, a fixed medication dosage amount, a target blood glucose range (e.g., correction target), and an insulin sensitivity (e.g., correction factor). In some instances, the easy bolus calculator may also include information, such as the patient’s insulin on board, in the determination of a recommended medication dosage amount. For example, a fixed medication dosage amount may be entered by meal (e.g., breakfast, lunch and dinner).

[00517] The Insulin Calculator Setup Interface screen 3800 includes amount entry boxes for each meal. A fixed medication dosage amount may be entered into the
