Apparatus and method of operating medico-technical devices

The present invention relates to an apparatus for operating medical devices Devices, in particular dialysis devices, with screen and touchscreen interface characteristic and means for displaying and / or modification Treatment data. The invention further relates to a method for operating medical devices Devices.

Screen units with touch-surfaces for the operation of medical devices Devices are known. In general, such control units used to the actual values ​​of patient or machine parameters by touching retrieve a corresponding field of the touch screen interface or to enter corresponding setpoints.

EP 0623357 describes an apparatus and method for dialysis, wherein the interface between the device and the user through such a touch screen monitor is realized. The monitor is used to query and input characteristic Dialysis parameters, such as the pumping rate, the ultrafiltration rate or the conductivity of the dialysate. The operator must to enter a Setpoint to the appropriately labeled with the name of the parameter touch panel to display and finally reaches a screen, in the determination of an appropriate value or a profile is possible. A generic device and a generic method are in US 5,609,770 discloses. Here also takes place by means of a touch-screen monitor a selection of interest dialysis parameters. After selecting can the parameters a desired setpoint can be associated with both the selection of the parameters and the entry of the value of a corresponding done touching the surface. Due to the number of variable Dialysis parameter contains a screen a correspondingly large number of selectable fields, resulting in a fast and reliable operation of the device difficult. An error-free operation is thus additionally hindered by the Fields have the same size and only because of their designation are distinguishable. Thus it is possible that, particularly under pressure, the false Fields of touchscreen interface be touched and thus, for example, an erroneous input of a setpoint parameter is carried out, which significant implications for the risk to the patient during treatment may have.

It is the object of the present invention, the handling of medical To simplify equipment and the probability of the occurrence of to reduce operator errors.

This object is based on a generic device and a generic method by the characterizing portion of claims 1 and 11 dissolved. The inventive device for operation of a medical Device comprises a screen and a touch-screen interface and first means for displaying and / or changing characteristic treatment data. Furthermore, second means for representing the components of the device characteristic icons are provided, the first means by contact the icons on the touch-screen interface can be controlled. To this It is achieved that confusion of symbols due to lack of Distinctness of largely affecting the fields touchscreen interface can be excluded. Rather, by simply touching the each symbol to be influenced component preparation of the corresponding Data, for example, in a control panel, activated. such graphical user interface allows for safe and reliable use For example, a dialysis machine. The medical staff is the characteristic symbols very quickly with the scope of the invention Device trusts, which firstly reduces the training time and the other enhances the reliability of operation.

It is particularly advantageous if at least one complete dialysis circuit with the symbols of the components contained therein is displayed. It can either the circuit of the dialysis liquid or blood, or both be illustrated circuits, wherein the components contained therein, such as Pumps, dampers, sensors or the dialyzer itself, means characteristic symbols can be displayed. The representation of the entire cycle facilitate the user's orientation in the selection of one or more the components of the dialysis circuit. The probability of the confusion various pumps, dampers, or as heaters is minimized in this way. It is also possible that only a part of the Components of a medical device, in particular a dialysis apparatus is or a dialysis circuit represented. Here, two or even more arbitrary components of the system and their functional relationship being represented. For example, it is conceivable that the dialyzer and the Blood pump and the two component connecting tubing by means of second means are displayable. The selection of items to display combinations of Components or extracts from the corresponding total investment, by Basic settings of the device or set by the operator as needed be designed. By depicting the functional relationships of the components the operation guidance is easier for these components.

In a further embodiment of the invention provides that the first and second Means are designed such that at the same time, the symbols displayed and the associated are treatment data can be displayed and / or changed. This leaves the accidental modification of a setpoint or the recording of an actual value prevent, as always at the same time the symbol of the component itself and the parameter to be changed are displayed.

The angezeigbaren by the first means and / or variable data treatment may the name and desired and / or actual values ​​and / or limits the device and / or patient parameters include. While under a Monitoring substantially the actual values ​​of the characteristic data of the components be queried, can be in another mode of the invention Device a targeted modification of setpoints perform. there it is possible not only individual setpoints, but according to a temporal Depending on the setpoints and thus predetermine a setpoint profile. Equally possible to define it for the characteristic data limits, compliance with which a dangerous operating condition avoids safely. The achievement of Limits can be visually or acoustically or even a shutdown of the device or to a closing dampers to lead. The data displayable by the first means and / or variable may involve other parameters and values ​​beyond, for example, the course the previous dialysis treatment or the storable program data previous treatments of different patients relate.

It is particularly advantageous if the means for by the contact of the symbols Change and the means for displaying the treatment data driven simultaneously are. In this way, control surfaces are generated, for example, the same time display the current values ​​of the corresponding parameter, and provided further, for example with arrows fields to that change the setpoints include. The change of data not only extend to: a change in the nominal value, but may, for example, a complete Absence or involvement of a component or functional unit of the device include.

It is also possible that at first to touch the characteristic symbols the components of the medical device an indication of the treatment data and in that the means for modifying the data by appropriate Touching the displayable treatment data can be controlled. Thus occurs after a single touch of a symbol at first only the display of Data and only in the event that these are to be changed is a new contact the touchscreen monitor required.

The components of the medical instrument that represented by symbols are, blood and Dialysatpumpen and / or agents can contribute to the Dialysataufbereitung and / or sensors. The sensors can be as Temperaturals be designed as a pressure transducer. It is also possible that the dialysis machine itself or shut-off devices, such as valves or clamps or also heating devices are displayed.

It is particularly advantageous when at the same time by the contact of a plurality of symbols more of the associated treatment data can be displayed and / or changed are. In this way it is possible, for example, a set of actual values ​​or also a list of setpoints by contact several or all symbols to obtain. Also, in this way a profile of the actual value curves of the previously treatment carried out or past treatments are obtained.

In a further embodiment of the invention provides that the first means such are carried out so that a time dependence of the treatment data can be predetermined is. In this way setpoint profiles can be predefined, whereby, for example, in Part of a dialysis treatment is usually successful treatment against can be improved fixed predetermined setpoints. Thereby, the setpoints in accordance with the timelines in form of a table or a similar listing be entered. It is also possible that the user through the touch an appropriate field of the touch screen surface a desired Course of the desired value as a function of time dictates. determines a computing unit in this case the desired nominal values, according to a predeterminable dialysis time are to be achieved.

It is particularly advantageous if the touch screen function of expiry Time interval after triggering or touching the touch-screen interface can be switched off is. It is thereby achieved that, when the last operator action or the last activation of the touchscreen interface back is a defined time, The touch screen function is turned off, whereby an accidental touch has no adverse effects. In particular, it can not be more to an accidental change of the display or even a change in the Setpoints patient or device parameters come. It is also possible, that simultaneously or with a time lag a display can be generated, a selection of characteristic data includes. This is a clear Display only relevant data generated, which makes it easier for the operator, to monitor a treatment process and to detect malfunctions significantly. The selection of the displayable in this manner is characteristic data directed by the operator or changeable by the device can be predetermined, and For example, according to the type of treatment. A particularly clear Display is achieved, when the selection of characteristic data in a magnified Display is.

The present invention further relates to a method for operation of a medical Device, in particular a dialysis apparatus. Here are the characteristic treatment data through a screen with touch-screen interface displayed in a first screen view and / or are modifiable, and in at least one second screen are used for the components the dialysis machine characteristic symbols shown. By touching these symbols is the first screen generated. The invention The method thus requires the user only touching the desired Symbol of the component, of which either the actual value or other Parameter to get or a setpoint is to be changed. After touching the characteristic symbol is done in an appropriate Screen, for example, one that displays the actual values ​​or other Data. It is also possible that not the display shows the data, but a change of the data is made possible. This is particularly desirable, for example, the actual values ​​of the parameters always together with the symbols of the components of the device are displayed, and a new Representation of these values ​​is not required. After viewing or changing the parameters, the first screen will be closed, and there is For example, a new representation of the symbols of the components of the device.

In a further embodiment of the invention, that by simultaneous or sequentially touching several symbols on-screen display is generated, the simultaneous display or changing of several treatment data allows. Thus, for example, at the same time the actual values ​​of all Treatment parameters can be displayed and therefore easily controllable.

According to another embodiment of the present invention, that touching the symbols displaying the corresponding treatment data Generated, and touching the displayed treatment data further Screen display generated, which allows to change this data.

It is particularly advantageous if the symbols of the components of the device always are displayed simultaneously with the associated actual values ​​of the parameters. A Such an embodiment of the method allows an overview of the current Data, without the need for intervention by medical personnel and necessary is. In this case, it is sufficient if the contact of the corresponding Symbols do not again lead to a display of the actual value, but for example, allows the change of the corresponding setpoint or other data.

In a further embodiment of the present invention it is provided that the Touching the symbols generates a screen through which the temporal A function of one or more of the treatment data is presented. For example, a time-varying ionic concentration of a dialysis solution required can by touching a corresponding icon and the temporal Dependence of this setpoint can be entered.
