The present invention relates generally to programmed medical devices, and more particularly to systems and methods for automatically confirming a drug to be infused into a patient.
Physicians and other healthcare professionals apply intravenous (IV) infusion therapy to treat a variety of medically cumbersome problems for patients. IV infusion therapy is a cannula inserted into the patient's blood vessel from a fluid source, typically a bag, bottle, or other container, through a tube or conduit in the fluid dosing set (IV set). Accompanied by injecting a medical fluid, such as a drug or nutrient. In a typical LTCF, a doctor writes medication instructions for a particular patient. This instruction may be treated as a simple prescription or entered into an automated system such as a physician order entry (POE) system. Send this prescription or electronic prescription from the POE system to the pharmacy, where it will formulate this instruction. Typically, the prescribed drug is prepared by a pharmacist and bagged or bottled at a pharmacy. Under the supervision of a pharmacist, the contents of this bag are identified by the body of the paper label affixed to this bag. The label may identify the contents of the bag by other means, such as barcodes, magnetic devices, or by radio frequency (RF) signal interactive devices such as RFID tags. The prepared drug is then delivered to the nurse station for later administration to the patient.
For safety reasons and for optimal results, this medical fluid is often administered in the exact amount prescribed by the physician and in a controlled manner using an infusion pump. The infusion pump operates to push the fluid from the fluid source through a tube into the patient by displacing the fluid from the fluid dosing set. The infusion pump is programmed with operating parameters such that an operator, such as a nurse or other healthcare professional, administers the drug as prescribed by the physician. Such actuation or pumping parameters are drug and patient specific. That is, these pumping parameters are selected based on the particular drug prescribed and the particular patient they intend. It is the nurse's responsibility to match the prescribed medication with the correct patient and with the properly programmed pump.
The LTCF is interested in providing a safe medication system in times of nursing shortages and constantly strives for quality patient management. Medical malpractice, such as when a patient receives the wrong drug or the right drug at the wrong time or at the wrong dose, is of great concern to all health facilities. With drug administration, the focus is typically on the following five "correctnesses": the right patient, the right drug, the right route, and the right time. Nurses aim to ensure that all of these "correctnesses" are achieved. Systems and methods that seek to reduce malpractice should also take into account these five correctnesses.
Drug infusion pumps have made great strides over the years, enabling more accurate infusion control and resulting in much better treatment for patients. The physician is assured that the dose and infusion rate prescribed for the patient will be accurately delivered to the patient by the infusion pump. This dosing may be done in small pieces or may be given at an essentially continuous rate. Infusion pump therapy may be electronically controlled to deliver accurate, metered doses at strictly defined levels, thereby injecting the drug gradually in favor of the patient. In this way, the injection pump can simulate the natural process of accurately maintaining the desired chemical balance by operating on a continuous time basis. However, there remains the ongoing concern of combining the right drug with the right pump.
One manufacturer has created a barcode system designed to reduce the risk of intravenous medication errors by automatically programming the infusion system to increase the chances of the right drug going through the right pump to the right patient. Such a system eliminates the error scenario caused by a clinician improperly programming the pump by providing a system that automatically reads the programming instructions and automatically programs the pump according to these instructions. Pursue that. Some of such systems can provide meaningful benefits, while others are by clinicians. Scanning barcodes on patient identification devices, Scanning barcodes on clinician badges, Scanning barcodes on the injection system, and IV Scanning of drug container label barcodes, Sometimes it involves considerable effort to do multiple times.
A system that achieves the objectives of a clinical barcode system, but is more automated and does not require much scanning of multiple barcodes is desired. Those skilled in the art recognize the need for a system that reduces the time it takes to initiate an injection and also has the safety features that are the goal of a barcode system. Unfortunately, barcode systems require some skill, whether they are working properly or not, and the clinician must manually enter the information into the appropriate medical device, typing or typing. With the risk of mistakes. Even when the barcode system is functioning properly, the clinician may mistakenly scan the label of another device that is very close to the label he wants to scan, especially when the scanning beam of the barcode scanner is wide. .. When barcode labels get wet with medical fluids, or become otherwise obscured for some reason, they are sometimes unreadable by barcode scanners, which requires manual entry of that information, which is not possible. There is a risk of accurate data entry.
There is a further problem with multi-fluid conduits when multi-channel pumps are involved. The same can occur when single channel pumps are involved, but many are mounted very close to each other.
In some cases, a patient may be prescribed multiple simultaneous injections for four or more different drugs, all of which may require multiple injection pumps that are programmed differently. In such cases, there may be multiple IV dosing sets, each with its own fluid conduit to connect to the patient. In the presence of multiple infusion ducts, there is concern that the fluid conduit may be installed in the wrong infusion pump channel or in the wrong infusion pump and the drug may be delivered with unreasonable pumping parameters. As an example, if multiple injection pump channels are located side by side, there is concern that the fluid injection line or conduit may be installed in the wrong pump channel. In the presence of a denser infusion pump environment, it is important to ensure that the correct medical fluid conduit is installed in the correct pump or "channel". Fluid sources for all pump channels may be suspended directly above these pump channels so that the conduits of the fluid dosing set become entangled, thus selecting the correct conduit for a particular channel of that pump. Make it more difficult to do.
Conventional attempts have been made to ensure that the correct drug is administered to the correct patient through the correct pump. In one example, a bar code label identifying the drug and patient was attached to the bag at the pharmacy. An operator like a nurse manually programs the pump, then uses a barcode scanner connected to this pump to read the barcode label on this bag, which is the same drug that was programmed into this pump. Verify that it identifies. In another example, US Pat. No. 5,078,683 outside Sankov discloses a bar code label on a bag that is read by a bar code scanner to automatically program the pump, thus avoiding manual programming altogether.
<p> The above mentioned items have made significant advances in this technology to avoid medication errors and reduced the possibility of such medication errors, but the wrong bag may be attached to the pump or pump channel. There is still some danger. In other words, there is still some danger that the bag may be connected to the wrong pump or pump channel. For example, a nurse would probably scan the bar code label on the correct bag, but would be distracted by attaching the medication set ducts connected to this bag to the wrong pump channel. Even if the nurse is not distracted, the various fluid conduits of multiple fluid infusions are difficult to distinguish from each other, especially if the fluid conduits are entangled with each other, it is possible to track the fluid conduit associated with the correct bag. It can be a nuisance. In such cases, the nurse may inadvertently choose to install the wrong fluid conduit in this pump, even after identifying the correct fluid source.</p><p> Therefore, those skilled in the art recognize that there is still a need for systems and methods to more accurately ensure that the correct fluid is injected into the patient with the correct pumping parameters. In addition, those skilled in the art recognize the need for systems and methods that allow more reliable determination of connecting the correct fluid source to the correct infusion pump or pump channel so that the fluid is infused into the patient according to the correct pumping parameters. There is. Moreover, those skilled in the art recognize the need for a system that achieves the objectives of a clinical barcode system without burdening clinicians with scanning multiple barcodes. There is also a recognition of the need for a more automated system that provides an automated injection setup, where the clinician only needs to verify the setup and then press the start button to start the injection. There is no need to manually scan labels or enter information manually, but there is still a recognition of the need to provide accurate medical information to the right device that is reliable and cost effective to use. .. The present invention satisfies these needs and others.</p><p> Simply and in general terms, the present invention provides a wireless, non-optical, medication information and pumping parameter reading device from a drug container with a panel above the drug delivery device, and a correct delivery device. Orients systems and methods for verifying that the correct drug is installed.</p>

For example, a barcode scanner with a wide beam may read the barcode in another container, perhaps not what it intends to read.
Each fluid container 26 contains a conduit 30 or IV dosing set for delivering the drug contained in this container to the patient. This conduit is typically made of elastic tubing material and may have parts such as flow clamps, inlets, and other devices made as part of it along its length. .. It may also have a portion specifically designed to operate with the peristaltic mechanism of the infusion pump so that the fluid moves accurately and reliably from this container to the patient. You will also notice that there are four conduits hanging from the four containers. It is likely that each container has a different drug and may need to be delivered to each patient at different dose rates. Therefore, it is important to ensure that the correct conduit is installed in the correct pump or in the correct channel of the multi-channel pump. Multiple ducts, as shown in Figure 1, can lead to dosing errors if the wrong duct is installed in the wrong pump channel.
Now, referring to Figures 2 and 3, the panel 40 was mounted on the IV column 42 (Figure 2) and was typically used to suspend the IV infusion vessel over the pump system and the patient (not shown). Useful as a substitute for the coat rack "20 (Fig. 1). This panel has four parts 44A, 44B, 44C and 44D in one embodiment, each of which comprises a hanger 46, an RFID reader 48, and a vibrating device 50 or a vibrating device. RFID readers, also known as RFID interrogators, include at least one antenna used to read or interrogate RFID tags. Such RFID tags may be passive or writable, i.e., configured to store the new data that the RFID reader has transmitted to them. RFID tags may be passive, writable, or attached to drug containers. As an example, an RFID tag attached to a drug container not only has relevant information about the drug in this container, but also the patient name; patient location; patient weight, gender, age; drug; concentration; dose rate; and Possibly other information may be specified. In some cases, the RFID tag attached to this drug container may include the entire set of pumping or operating parameters so that the infusion pump can be fully configured automatically by reading this RFID tag.
In FIG. 4, the IV label 26 is actually affixed with an RFID tag or label (responder) 52. In one embodiment, a LTCF pharmacy prepares an RFID tag and attaches it to a container. Other methods of preparing and attaching this RFID tag are also possible. Preparing this RFID tag involves programming it with the required information, as discussed above. In one embodiment, the pharmacy may receive an empty container with an RFID tag already attached to the container at a particular location, so that the RFID reader on panel 40 may have a very low power output at this particular location. You can expect the RFID tag attached to the container at. In this embodiment, the RFID reader does not have the opportunity to inadvertently read the RFID tag on a nearby bag. The RFID tag of this container may be programmed with the correct information and shipped to the patient's location before or once the container is filled with the appropriate drug. The pharmacy may program the RFID tag for this container, or another entity may program this.
When one of these IV bags 26 with an RFID tag programmed by a clinician is hung on panel 40, the RFID reader 48 on this panel can read this RFID tag and obtain the information contained therein. This is an RFID reader that is then located close to the target RFID tag of this drug container 26 and has a limited read range so that this RFID reader does not inadvertently read tags that are not nearby targets. Related to. Using a panel with multiple RFID readers to apply multiple IV solutions may inadvertently read different tags and in any case is a time-consuming and labor-intensive hand scanner. Need a way to read those RFID labels or tags without using. This panel approach also requires the ability to identify the correct channel of the infusion multi-channel drug delivery device or infusion system 54, thereby eliminating the infusion conduit replacement error.
RFID readers and vibrating devices require power to operate. Fortunately. The new device requires much less power to improve operating efficiency. In either case, the RFID reader needs enough power to identify the RFID tag on the drug container and successfully obtain the information on that tag, and the vibrating device propagates and injects the drug with sufficient strength. Sufficient power is required to reach the upstream pressure sensor of pump 52. This upstream pressure sensor is so called because it is located downstream from the vibrating device and upstream from the pump mechanism of the injection pump. There are various possibilities to provide such power. The panel 40 itself may be connected to a power source in some way, or the devices 48 and 50 may be self-powered. This can possibly be achieved in several ways, some of which are: 1. The panel may be wired to the injection pump or the plug of the injection pump controller 58. 2. Bluetooth technology may be used. The controller 58 of the injection pump 56 can communicate with the panel 40 via Bluetooth communication. 3. The passive receiver 70 mounted on the IV column 42 in close proximity to the controller 58 can transmit the radio signal sent from this controller to the panel 40. This signal can be transmitted via the metal of the IV strut or via the wiring connection. 4. Direct connection. The transmitter (questioner) 72 in the control device 58 can send a signal to the panel 40 using the IV support 42 as a conduit. However, this may eliminate the possibility of multiplexing the signal.
There are different options for panel 40 power. In one example, all panels and all of their components may be powered by batteries or battery sets (not shown) within the panels. This battery powers all RFID readers 48 and vibrating devices 50 and is easily replaceable. In a more detailed embodiment, the panel may include a battery strength or "remaining life" indicator (not shown). In a more advanced version, this battery indicator may display its remaining "run time". In another embodiment, the RFID reader is mounted on this panel so that it is easily replaceable and has its own internal power supply. In this case, even if the battery of one RFID reader runs out, all the panels will not be deactivated. The vibrating device may also be mounted so that it is easily replaceable and may have its own built-in or internal power supply. If the battery of one vibrating device runs out, the panel may still operate on three other vibrating devices with active batteries.
A suitable system is to provide the control device 58 with an RFID reader antenna 72 or the injection device 56 with a passive antenna 70 on a column 42 located near the control device RFID reader antenna 72. This controller RFID reader not only provides a signal to this passive stanchion antenna, but also to a drug container fitted with a panel RFID reader so that the panel RFID reader can read the RFID tags on these containers. It also supplies the power needed to operate. This controller RFID antenna will also supply sufficient power to this passive antenna to power all panel RFID readers and vibrating devices.
RFID interrogators 48 are shown in FIG. 4 as being mounted on panel 40, but they may be mounted on hooks 46 on this panel in other embodiments and from their hook positions to the bag. The attached RFID tag 52 may be read. These RFID tags may be attached to the bag in a position different from that shown in FIG.
In another embodiment, the information from the four panel RFID readers 48 can be multiplexed by the multiplexing device to allow the control device 58 to communicate with all RFID readers, each with a unique indicator. After assigning or associating an RFID reader with controller 58, the logic programmed into this controller will be able to pole or contact individual RFID readers when necessary or in sequence with all RFID readers. The logic programmed into this controller 58 will identify each of the four IV bags 26 hanging on the panel 40 based on the signal strength of the RFID reader and the vibration generated by the vibrating device, as described in detail below. .. If the IV bag is placed in channel "A" position 44A on the panel and the door 74 of channel B pump module 56 is opened, this controller warns the clinician to hear and possibly through display 76. right.
However, it would be beneficial to keep the interrogator panel 40 passive (no power) and not directly attached to the controller 58 (no wiring). If the antenna panel is attached to this controller, there is a risk that the clinician may disconnect this connection when removing the controller from the stanchion 42. Therefore, it is desirable to make a wireless or non-connection connection between the control device and the interrogator panel.
The injection system of FIG. 4 includes a controller 58, three injection pump modules 56, and an RFID reader module 78. Further details of such a modular injection system can be found in Eggers US Pat. No. 5,713,856, entitled "Modular Patent Management System", which is incorporated herein by reference.
Now, with reference to FIG. 5, a block diagram of a medication safety system 80 with a multiplexed RFID interrogator panel 40 according to aspects of the invention is shown. In this diagram, channel 1 portion 82 of the panel is shown the same as channel 2 portion 84. Container channel 1 26 and Container channel 2 26 are shown suspended from this panel. Each part and each container has an RFID reader 48 and a vibrating device 50. The block indicating the container also indicates that each container has, in one embodiment, an information device 52 which is an RFID tag programmed with certain drug information. Downstream of each container are vibration sensors 86 and 88 and pump mechanisms 90 and 92. The vibration sensor may include a pressure transducer designed to convert the pressure change of the fluid in the conduit 30 into an electrical signal. Such pressure changes may result from a variety of conditions, such as when the volume of fluid in a drug container decreases over a period of time. In some cases, pressure changes occur rapidly or in a short period of time, such as when the drug container is lowered or moved. Moreover, pressure changes may occur periodically and even more rapidly, such as when the vibrating device vibrates the fluid in the vessel. In either case, the conduit 30 or IV piping acts as a conduit for transmitting these pressure changes to the pressure transducer of the injection pump module 56. This converter transmits an electric signal representing a pressure change to the control device 58.
It should be understood that the term "oscillating device" is used for easy reference and is meant to include devices that cause pressure disturbances or changes in the fluid in accordance with instructions from controller 58. This vibrating device is adapted and positioned to create a pressure disturbance with a frequency and sufficient intensity or energy to propagate to the vibrating sensor of the drug delivery device. A frequency of about 20 Hz is preferred, but lower or higher frequencies may be used. It is not intended to limit this vibrating device to devices having mechanical vibrating elements that come into contact with the vessel 26 or conduit 30. Moreover, although the vibrating device 50 is located adjacent to the vessel 26 in FIG. 4, another embodiment vibrating device (not shown) may be located adjacent to or coupled to the conduit 30 extending from the vessel 26. ..
It should also be understood that the terms "upstream" and "downstream" refer to a reference frame along the vessel 30, as shown in FIG. The upstream element of this conduit is closer to the vessel 26 than the downstream element of this conduit. Conversely, the downstream element is closer to the patient than the upstream element. Within the flow control device, such as the injection pump module 56, there is an upstream portion 31 and a downstream portion 33. The upstream portion 31 of this flow control device begins at the point where the conduit enters the device from this container and ends at the point where the flow control device is located within the device, such as a valve or pump mechanism 90, 92. The downstream portion 33 of the flow control device begins near the point where the flow control device is located and ends at the point where the conduit exits the device towards the patient. As shown in FIG. 5, vibration sensors 86, 88 or upstream pressure sensors are connected to their respective conduits 30 at the upstream portion 31. A downstream sensor (not shown) is connected to the conduit at this downstream part to allow detection of conduit blockages or other fluid delivery problems that occur beyond the point where the conduit exits the injection pump module. You may.
The panel RFID reader 48 and vibrator 50 are connected to a passive antenna 70 (shown in two parts for ease of illustration). In this case, they are connected by wiring, but in other cases they may be connected wirelessly. The control device 58, which controls the operation of the pump mechanisms 90 and 92 and receives signals from the downstream vibration sensors 86 and 88, also communicates wirelessly with the passive antenna 70 in this case. Therefore, there is a communication path between this controller and each RFID reader 48 on the panel 40 and between this controller and each vibrating device 50 on the panel. In other embodiments, there may be no direct communication path between the controller and each vibrating device, but instead, the vibrating device, such as by actuating an RFID reader 48 on the same panel portion 82. , May be activated by other means.
The controller 58 is also connected to memory 90, in which, or in connection with it, a database 92 of a range of acceptable drug delivery parameters. This memory and / or database may be located locally or far away from this controller. In one embodiment, the memory and database may take the form of drug library 94. See Ford's US Pat. No. 5,681,285, incorporated herein by reference, for further details and information regarding the drug library example. Obtaining usage from the information device 52 of each container 26, the controller compares it to the database to determine if the sending parameters of this information device are within the permissible range of this database. If so, the controller then automatically programs each pump with these parameters. If these parameters fall outside the "soft" range or limits, the controller may also issue a visible and audible warning to the display 96. This controller may allow clinicians to ignore soft limit breaches and continue infusions. If the drug delivery parameters fall outside the "hard" range or limits, the controller will still issue visible and audible warnings, but may not allow clinicians to ignore this limit. The above process of obtaining information from an information device, comparing this information with a database, and issuing a warning is performed under the direction of the sending parameter verification system.
The control device 58 is also connected to the reading device 98 to read the patient identification device 100 in this embodiment. This allows the pump 56 associated with or controlled by this controller to be associated with the patient. The controller may then ensure that all containers 26 suspended from the panel 40 are actually for the patient associated with their respective pumps. This adds an additional hierarchy of safety to the automated pump programming process. The reader 98 of this example can also be used to identify the clinician's identification device 102. Such information may be used for archival purposes or for controlling access to the pump. This controller compares the clinician identified by reader 98 with a database of certified clinicians, and if this clinician is not in the database, this controller may not allow this infusion to be performed. The reader may take the form of a barcode reader, RFID reader mounted in the controller housing, or other form, as shown in FIG. If you use a reader mounted in the housing, you will be able to get the identification information automatically without having to use a handheld barcode scanner.
Also shown in FIG. 5 is a data and regulatory input device 104 to control device 58, which may take the form of a keypad, keyboard, or other device connected to this control device. It may be used by clinicians to ignore soft limits and for a variety of other applications.
Now, referring to the flow chart of FIG. 6, an example of the operation of the medication safety method including the multiplexed RFID interrogator panel is shown. At block 110 110, the patient is associated with the pump. Then hang the drug container and associated fluid dosing set and prepare 112. For multi-channel pumps, open one door of the pump channel 114, thereby selecting it as the then active device for programming the pump. Panel 40 (Figure 4) of the panel associated with that pump channel (eg, part 44A of the panel is associated with channel A of the pump) activates the RFID reader 48 to read the information device on this drug container 116. Next, the drug delivery information read from the RFID tag (information device) 52 on the container 26 is transmitted to the control device 58 118. The associated vibrating device 50 on the panel 40 is then activated to generate mechanical vibrations in the medical fluid in this container 120. Check patient identification 122, if wrong 124, this drug must be checked again 116. At the same time, the vibration sensor 86 or the upstream pressure sensor of the pump channel is inspected to determine if the conduit 30 attached to that channel is vibrating 126. If no vibration is detected 128, the clinician will be informed and the duct from this container must be transferred to the correct pump channel 114.
This controller collates the drug delivery parameters obtained from the drug container with a database of tolerances and parameters130. If unacceptable 132, there may be a possibility of ignoring the program 134. If the parameters are acceptable, the clinician can start the injection by pressing the start key136. The start key is found and more fully described in Eggers' US Pat. No. 5,713,856, entitled "Modular Patent Management System," which is incorporated herein by reference.
In another embodiment, the clinician also uses his employee badge 102 (Figure 5) or other personal device (including an RFID responder) and puts it inside an RFID interrogator / reader (not shown). It may be necessary to associate itself with the injection system 80 by placing it close to the controller 58 containing).
When it is necessary to administer the medical fluid of the second container to the patient, the clinician hangs the first container on a small hook (not shown) attached to the lower end of the panel 40 and lowers it. Suspend the second vessel in place of the first vessel and connect the conduit of this second vessel to the mouth, such as the Y-shaped connector attached to the conduit of the first vessel. This mouth is preferably located between the first container and the injection device 56. In this way, the fluid from the second container is delivered to the patient through the conduit in the first container. The system recognizes a second container placed in place of the first container and programs the injection to a second volume rate. This second container detects pressure changes upstream from the injection device by vibration sensor 86 or upstream pressure sensor, or by periodically polling or reading RFID tags within the distance range of the RFID interrogator. , Recognized by this RFID interrogator 48. Completion of this second injection can be signaled, at least in part, by the rate or pattern of recognizable pressure changes that occur after the second vessel is emptied. When the second infusion is complete, the controller switches to the first volume rate and informs the clinician to place the first container in its original position.
The systems and methods according to the invention provide a medication safety system by passively achieving infusion pump programming and verifying that the correct drug was given to the correct patient at the correct time and at the correct dosage and infusion rate. provide.
The term "control" as used herein is used to control the operation of the pump system, as in the Medley® patient management system distributed by ALARIS products from Cardinal Health (San Diego, Calif., USA). It means to refer to a usable programming unit. However, it is simply such as the Signature Edition® pump, also distributed by ALARIS products from Cardinal Health (San Diego, Calif., USA), or any other medical device that can be programmed to introduce fluid into the patient, as appropriate. It may refer to the programming of one pump. The system according to the invention can be used in connection with the Medley patient management system and the signature edition infusion system to provide an easy dosing system at the bedside. The infusion setup, according to the system, would only require the clinician to validate this setup, in some cases, by pressing the start key on the pump or controller 56. Infusion safety will be improved by verifying that the correct drug was given to the correct patient at the correct time and at the correct dose and infusion rate.
The panels 40 shown in FIGS. 2, 3 and 4 may be attached to the stanchions 42 by standard stanchion clamps (not shown) used in the medical field. For example, strut clamps such as those shown in Figure 3 of US Pat. No. 6,593,528 can be used for such purposes. The strut clamp may be permanently provided on the back of the panel and secured to the strut when the panel needs to be used. This allows for panel mobility. In other cases where standard stanchions are required, this panel can be easily attached to such standard stanchions.
In another embodiment, the back surface of the panel 40 may have two or more strut clamps that are laterally spaced apart. The strut clamps are preferably located in three different positions on the panel, center, left, and right, so that the panel can be offset when using two controls 58. Multi-post clamps provide additional versatility for placement and knitting. For example, a pair of injection pump modules 56 mounted on the left side of the first controller 58 can be used with a first panel mounted offset to the left. The second pair of injection pump modules 56 mounted on the right side of the second controller 58, mounted under the first controller, together with the second panel 40 mounted offset to the right under this first panel. Can be used. In this way, the container and the first pair of infusion pump containers and conduits are kept away from the first pair of infusion pump containers and conduits, thereby eliminating conduit replacement errors.
The syringe may also have an RFID label and may be read directly from an RFID interrogator attached to the syringe module of the modular infusion system. The syringe adapter may have a built-in interrogator that couples with this system when installed. From the above, it will be found that the systems and methods according to the principles of the present invention provide an effective means of determining that the fluid source is properly connected to the infusion pump to ensure proper drug infusion. ..
