FIELD

The present disclosure relates to a display device of a medical treatment apparatus, especially a dialysis machine for displaying various parameters at least containing a set or a quantity of preferably patient-related treatment parameters and a set or a quantity of preferably clinic-related CIS parameters.

BACKGROUND

It is known from prior art that during treatment, especially during a dialysis treatment, users have to resort to a clinical information system. The clinical information system (in English abbreviated CIS), hereinafter referred to as “CIS”, is understood to be a computer-aided system which serves for detecting, storing, manipulating and providing clinical information that is important to the health care process. A CIS may be limited to one single field such as e.g. a dialysis system, laboratory system etc. or may be more wide-spread and comprise practically all aspects of clinical information such as e.g. electronic medical records. Accordingly, the CIS offers a clinical data memory which collects, stores and administers information about the patient ranging from his/her personal data such as name, age, address and sex to all aspects of the treatment by the hospital. Moreover, the users may utilize tools by which appropriate information can be detected, manipulated, applied and displayed so that correct, prompt and evidence-based clinical decisions can be taken. In other words, the CIS represents a central collection of different information for patient care at spread locations.

Moreover, it is known from prior art that for access to the CIS during dialysis treatment a “COW” (computer on wheels) is provided. The COW is a “Thin Client” separate from the dialysis machine and flexibly movable which has enabled the CIS to be accessed so far. A Thin Client is understood to be a computer or a program that requires assistance by a server to be capable of fulfilling its tasks. In prior art, the Thin Client is connected to the CIS server so as to access and update data and information of the CIS during treatment via the COW. However, it is a drawback of this solution that the COW is an additional external apparatus which, in addition to the dialysis machine, requires space and is used for two patient beds. The latter aspect entails mainly concerns relating to hygiene.

It is further known from prior art that the Thin Client may be integrated in the dialysis machine. One example hereof is a system by Fresenius marketed under the trademark or tradename 2008T CDX™. The FMC CDX SYSTEM™ (Fresenius Medical Care Clinical Data Exchange) is a small computer which is incorporated in the dialysis machine and allows the users such as the caregivers or physicians to access the information system from any dialysis place. Thus, all information entered is immediately detected and uploaded into the information system without the user having to leave the dialysis area to change to a central computer.

Here the system has exactly one display which is integrated in the dialysis machine and a so-called CDX key which is adapted to switch between a treatment screen and the screen for displaying the CIS. It is a drawback in this case that the Fresenius CDX solution can display either only a set of patient-related treatment parameters or only a set of clinic-related CIS parameters on the display of the dialysis machine and between said two display configurations it can be switched only by means of an extra key on the input unit/operating unit. In the following, the two display configurations are referred to as treatment configuration and CIS configuration.

Moreover, practically all superior dialysis machines currently on the market have a 15″ monitor with a 4:3 aspect ratio. The graphical user interface is geared to said format of the displays of the dialysis machines.

SUMMARY

Therefore, the object underlying the invention is to provide a display device of a dialysis machine which allows both simple operability and clear representation of various parameters on a display and enables CIS to be used along with a dialysis machine without any additional external devices.

The general idea underlying the invention is to provide exactly one display which is integrated in the dialysis machine and includes at least one input unit adapted to individually modify at least a set or a quantity of preferably patient-related treatment parameters and a set or a quantity of preferably clinic-related CIS parameters.

A set or a quantity of preferably patient-related treatment parameters are understood to be current values of the patient that are being continuously recorded and shown on the display, such as blood flow, blood pressure, dialysis fluid, ultrafiltration, limit values, heparin, time lapsed etc. The set or the quantity of preferably clinic-related parameters corresponds to the afore-mentioned explanation in prior art.

According to the underlying general idea, switching between the set or quantity of preferably patient-related treatment parameters and the set or quantity of preferably clinic-related CIS parameters is intended to be easily operated and to be possible without a shift key provided just for this purpose on a keyboard. Moreover, both the set or the quantity of preferably patient-related treatment parameters and the set or the quantity of preferably clinic-related CIS parameters are intended to be shown simultaneously on a display, when needed.

In detail, the display device of a dialysis machine for displaying various parameters includes exactly one display having a display area virtually divided into two display panels, the first display panel of which has large dimensions and the second display panel of which has small dimensions and includes at least two pre-set display configurations which can preferably be switched via the input unit, concerning a treatment configuration in which the set or the quantity of preferably patient-related treatment parameters is displayed exclusively in the first display panel and the set or the quantity of preferably clinic-related CIS parameters is displayed exclusively in the second display panel, and concerning a CIS configuration in which the set or the quantity of preferably patient-related treatment parameters is displayed exclusively in the second display panel and the set or the quantity of preferably clinic-related CIS parameters is displayed exclusively in the first display panel.

It is preferred in this context when the first display panel has a 4:3 aspect ratio. This is based on the fact that the dialysis machines currently on the market are configured with a graphical user interface (hereinafter referred to as GUI) corresponding to said aspect ratio as afore-described. When the aspect and/or size ratio is maintained, the effort of modifications on the graphical user interface for the first display panel is considerably minimized and the implementation can be realized with little effort as the 4:3 GUI can be continued to be used. This side-length ratio of the first display panel corresponds to the pre-set configuration for both display configurations.

The user may deviate from said pre-set configuration by dynamically varying the size of the first display panel manually by drawing the boundary between the first and the second display panel by the finger. Such variation is possible until the ratio of the first display panel to the second display panel is 50:50, for example. It depends on the information to be displayed which ratio will be set.

It is further advantageous when the display is in the form of a touchscreen and the input unit may be operated by touching the display. Alternatively, also a keyboard alone or in combination with a computer mouse or in combination with a touchscreen or a combination of all three input units is imaginable. In this way, switching between the two pre-set display configurations is possible by simple touching. Necessary inputs or adaptations of values, for example, are made preferably directly on the display, thus saving a separate keyboard which in turn requires space. A virtual keyboard may be automatically or manually overlaid on the screen, where needed.

In the CIS configuration, viz. when the set or the quantity of preferably patient-related treatment parameters is shown in the second display panel and the set or the quantity of preferably clinic-related CIS parameters is shown in the first display panel, the preferably patient-related treatment parameters are preferred to be reduced to the most important parameters such as e.g. the time lapsed, the blood pressure and the filtration.

The first display panel is preferred to be prioritized on the display area and to be manually shifted preferably via the input unit while the second display panel is automatically displaced or split. Thus, the first display panel can be displayed in the middle of the display. In this case, the second display panel is split into two parts. A respective part then is located on each side of the first display panel. The first display panel is always in the fore and is neither split nor concealed completely or partially. As an alternative, the first display panel may be disposed at the edge of the display. In this case, the entire second display panel is located either on the left or on the right of the first display panel.

By using the input unit in the form of a touchscreen according to the foregoing description, the first display panel may be positioned freely on the display by touching and correspondingly drawing said first display panel.

It is of further advantage when in the treatment configuration the set or the quantity of preferably clinic-related CIS parameters is shown in the second display panel in a sub-frame mode whose proportion to the area of the second display panel is especially automatically adapted in a preferably variable manner such that the side-length ratio thereof remains unchanged irrespective of the representation thereof in the first or second display panel. In other words, this means that the area of the second display panel occupied by the set or quantity of preferably clinic-related CIS parameters is adapted to the positioning of the first display panel in the treatment configuration. The type sizes are appropriately scaled, but do not go below a minimum font size required for readability.

In detail, this means that, when the first display panel is arranged on one side of the display, the addition of the horizontal length of the first display panel and of the horizontal length of the second display panel results in the horizontal total length of the display. In this context, the side-length ratio of the set or quantity of preferably clinic-related CIS parameters is maintained at 4:3 corresponding to the first display panel. Merely the size is varied. When the first display panel is arranged in the middle of the display, the set or the quantity of preferably clinic-related CIS parameters is displayed either on the right side or on the left side. Accordingly, in turn only the size but not the side-length ratio of the area occupied by the set or quantity of preferably clinic-related CIS parameters is varied. The horizontal length of said occupied area corresponds to the horizontal length of the second split display panel in which the set or quantity of preferably clinic-related CIS parameters is shown. The representation of the set or quantity of preferably clinic-related CIS parameters will be referred to as minimized window in the following.

Analogously, the invention is also applicable to a 16:9 display placed on edge, with the windows then being superimposed instead of being juxtaposed.

Of preference, in the treatment configuration the set or quantity of preferably clinic-related CIS parameters has been shown in the second display panel in the sub-frame mode only when the preferably clinic-related CIS parameters are processed/stored/updated. The time at which the preferably clinic-related CIS parameters are treated/processed/stored/updated will be referred to as CIS session in the following. After the set or quantity of preferably clinic-related CIS parameters in the CIS configuration has been treated or updated by a user during a CIS session and the user changes to the treatment configuration before the CIS session is completely terminated/concluded, the set or quantity of preferably clinic-related CIS parameters is continued to be shown in the second display panel. This is done as long as the CIS session is run in the background to process/store/update data. As long as the CIS session is active, switching to the CIS configuration is possible by touching the minimized window which is in the sub-frame mode. Thus, the minimized window of the CIS session serves as an icon.

It is advantageous when both in the treatment configuration and in the CIS configuration in the second display panel at least one button serving as an input unit is provided. The arrangement of the at least one button depends on the positioning of the first display panel on the display. This means that the at least one button spreads in the second display panel corresponding to the position of the first display panel. Depending on which of the two available display configurations is shown in the display, the arrangement of the at least one button adapts preferably automatically. This is to say that in the CIS configuration both the at least one button and the data reduced to the most important treatment parameters, as afore-described, are accommodated in the second display panel. This is applicable mutatis mutandis in the treatment configuration to the display of the active CIS session in the minimized window and the at least one button.

A button may be configured in different shapes/symbols and different functions may be assigned thereto. It is preferred when in the second display panel a button for starting and, resp., stopping the treatment, buttons for manually increasing and, resp., reducing values, preferably in the form of arrows, as well as a return button and a mute and sound button are provided. Further, an emergency button may be provided for simultaneously placing plural parameters in an area preferred in the case of emergency.

Preferably, the display of the display device for representing the first display panel and the second display panel has a total side-length ratio of16:9. The use of a display having such side-length ratio offers the advantage that the general trend of the market not related to medical treatment apparatuses, especially dialysis machines, toward screens having a 16:9 format may be followed and thus no completely new screen formats have to be produced. This aspect in turn has a positive effect on the costs. When using a 16:9 screen in combination with a first display panel on the display according to the afore-described4:3aspect ratio, a residual area is remaining. Said residual area defines the second display panel. Analogously, displays having similar aspect ratios such as e.g. 20:10 may be used, of course.

Advantageously, a height resolution of the display is identical to a height resolution of the first display panel both in the treatment configuration and in the CIS configuration. This offers the advantage that the area of the first display panel corresponds to the otherwise customary 4:3 screen as to size and format and thus the already present GUI may be taken over. In this way, the same readability is ensured for the GUI without re-sampling/re-scanning the same.

Accordingly, the first display panel is preferred to be designed with 1024×768 pixels corresponding to a 4:3 aspect ratio and the second display is preferred to be designed with 768×342 pixels.

Moreover, the set or quantity of preferably clinic-related CIS parameters is preferred to be represented in the first display panel and/or in the second display panel by a process independent of the set or the quantity of preferably patient-related treatment parameters. Hence, the CIS session is preferably run in a browser window which shows the preferably clinic-related CIS parameters. Said independence of the two processes increases the safety of the apparatus and thus of the patient as well. If, for example, the CIS session crashes, the treatment may continue to be run without the patient's health being endangered. A different example relates to the situation that, if unauthorized persons/hackers access the CIS server, the treatment data cannot be directly accessed and finally manipulated, which might become dangerous to the patient's life.

According to another aspect of the invention, it is of advantage when the dialysis machine is designed to include a display device according to any one of the preceding aspects.
