Description

Technical Field

[0001] The present disclosure relates to a method and an apparatus for checking the functionality of a medical device. Background Art

[0002] Augmented reality (abbreviated AR) is a computer-assisted extension of the perception of reality. This information addresses all human sensory modalities. However, augmented reality is usually understood to mean only the visual representation of information, i.e. the addition of computer-generated supplementary information or virtual objects to an image or video by superposition / overlay. In football broadcasting, augmented reality is the use of distance superpositions such as circles or lines in the case of free kicks.

[0003] Dialysis equipment / dialysis machines allow patient-specific removal of dissolved substances (e.g., urea, creatinine, vitamin B12 or β2-microglobulin) and, if necessary, removal of a defined water content from the blood in renal replacement therapy. Dialysis equipment is used for hemodialysis and hemodiafiltration. Basically, the dialysis equipment can be divided into the following modules: extracorporeal blood circuit, dialysate circuit, disinfection unit, operating unit and power supply unit. In addition, consumable materials, so-called disposables, are used during the treatment. These disposables are, for example, dialysate cannulas, blood tubing systems, dialyzers, dialysis concentrates, etc.

[0004] A disadvantage of the prior art is that special user training is required for caregivers to use the dialysis apparatus or to properly attach disposables to the dialysis apparatus. Such user training is necessary for each new generation of dialysis machines. Summary of the invention

[0005] The object of the present disclosure is to enable fast, efficient and error-free application of disposables as well as fast and safe self-testing through internal and external information.

[0006] This object is achieved by the technical solution according to the invention. Advantageous embodiments or further developments are explained below.

[0007] The present disclosure relates to a method for activating a function of a device, preferably a medical device, comprising the following steps:

[0012] In other words, the at least one CPU / computing unit receiving the image from the camera identifies the status / installation / setup / assembly stage of the medical device, preferably the dialysis machine. In this regard, the camera and, if applicable, the CPU / computing unit may be accommodated or integrated in the AR device, preferably on smart glasses. The at least one CPU / computing unit superimposes the necessary steps to be performed by the user, for example for correctly connecting a disposable to the medical device, into the field of view of the AR device, in particular the smart glasses (preferably, a projector connected to the CPU superimposes the information).

[0013] When the CPU recognizes via the camera arranged on the AR device that the setup has been properly completed, the CPU starts the device for a functional test via a preferably wireless connection, preferably by Bluetooth or WLAN (ZigBee, NFC, mobile radio).

[0014] Alternatively or in addition, the CPU or data transmission device on the AR device is configured and debugged to transmit the image of the camera to another second or fixed CPU. Preferably, this CPU is located in the medical device, but it can also be external to the AR device and / or medical device, for example, in the form of a PC connected to the medical device. This second or fixed CPU preferably has a greater computing power than the first CPU, which, if applicable, is located on the AR device. The second CPU processes the received data and transmits the processed data back to the first CPU or the data transmission device on the AR device, which then causes the information to be displayed in the field of view of the AR device. In other words, the first CPU on the AR device is used to transmit the data and control the display of information, while the second external or fixed CPU is used as a data processing unit and a computing unit for processing the captured image and deriving, for example, action steps therefrom, which the second external or fixed CPU returns to the first CPU as specific information to be displayed, as described above.

[0015] Preferably, the device is a medical device, and more preferably a dialysis apparatus, a dialysis machine, a syringe pump or the like.

[0020] Preferably, the device performs a self-test / functional test / pressure self-test etc. in response to the input of the camera. Here, the functional test may be activated after manual confirmation on the medical device itself, or by a gesture identified by the camera and the CPU, or simply after a predetermined time. For example, a pressure self-test may be started after connecting a pressure sensor.

[0051] Figure 1A system 1 for activating a function or functional test of a medical device according to the present disclosure is shown in a schematic diagram. A camera 4 is attached to / in an AR glasses (AR device) 2 and includes a defined field of view 6. The field of view 6 includes, for example, a dialysis machine 8 as a medical device, the medical device having a disposable 10, the disposable 10 being attached to the medical device and in this case being a line (blood line, dialysate line) intended for replacement and a dialyzer of the dialysis machine 8. In addition, at least one CPU connected to the camera 4 is provided. This CPU may be a fixed, possibly device-specific computing unit or a mobile AR glasses-specific computing unit, in which case the AR glasses may only have a data transmission unit. A CPU (not shown), preferably located in the dialysis machine 8 and / or on the AR glasses 2, identifies the actual arrangement (actual state) of the disposable 10 and compares it with the desired arrangement (desired state) stored in the storage medium of the CPU or retrieved via WLAN by an image analysis algorithm. If the algorithm identifies that the disposable 10 is not correctly / not fully attached, a correction step in the user's field of view corresponding to the field of view 6 of the camera 4 is superimposed in the AR glasses 2. If the algorithm identifies that the disposable 10 is correctly attached, the CPU issues a command to the dialysis machine 8 to perform a function or a function test, preferably via WLAN or Bluetooth, etc. If the function test is positive, this is displayed on the AR glasses 2. If the function test is negative, the corresponding required correction steps are displayed on the AR glasses 2.

[0052] Figure 2 A method for activating a function / functional test of a device (dialysis machine 8 ) is shown taking into account the above system 1 .

[0053] In step 112, the camera 4 identifies the actual state of the dialysis machine 8. In other words, the camera 4 captures one or more images which display / document the current actual state.

[0054] In step 114, the CPU compares the actual state of the dialysis machine 8 with the desired state of the dialysis machine 8. In other words, the image from the camera 4 of step 112 is compared with the stored image on the CPU and pattern recognition is used to determine whether the current state corresponds to the desired state. If such a comparison is not possible, for example due to an unsuitable image, step 112 is performed again until an image showing the actual state is obtained and can be compared with the desired state. This repetitive process or the presence of an unsuitable image can be displayed on the AR device, for example, with a preferred message / correction instruction indicating, for example, that a change in the viewing angle is required. If a comparison of the actual state with the desired state is achieved, the next step is performed.

[0055] In step 116, the CPU transmits a command for starting a functional test to the dialysis machine 8. In other words, once the CPU has made a positive comparison and evaluation, a command is issued to the medical device / dialysis machine instructing a functional / functional test to check whether the components perform in a functionally correct manner.

[0056] In step 118, the dialysis machine 8 performs a function or a function test. In other words, a corresponding action is performed on the dialysis machine 8 in response to a command from the CPU.

[0057] In step 120, the dialysis machine 8 transmits the functional test result to the CPU, or the CPU measures the test result and then displays the result graphically on the AR glasses 2. Here, the result is preferably the pressure / pressure curve prevailing / induced for test purposes in the disposable / line.

[0058] Figure 3 The schematic diagram shows a Figure 2 Augmented reality guided system 1 for activating a function or functional test of a medical device according to the present disclosure. A camera 4 is attached to / on the AR glasses 2 and includes a defined field of view 6. The field of view 6 (corresponding to Figure 3 ) includes, for example, a dialysis machine 8 (medical device) having disposables 10 (e.g., fluid lines, tubing, dialyzers, etc.) attached thereto. Windows 122, 124, and 126 are superimposed in the field of view, as well as arrows representing instructions for processing (e.g., a straight arrow next to window 122 and a semicircular arrow next to window 124). The first window 122 may include instructions such as "Put the tube through the connector." The second window 124 may include instructions such as "Insert the blood collection tube into the blood pump as shown in the video." The size of the third window 126 located at the bottom edge may be different from the size of one of the other windows, for example, larger, and a video, for example, a YouTube video, may be shown in this window.

[0059] Figure 4 A schematic diagram showing possible interactions between an AR device, a user, and a CPU. Figure 4 , the method is divided into method steps performed by the AR device (see column 128), method steps performed by the user (see column 130), and method steps performed by the medical device (see column 132).

[0060] In step 134 , the AR device and the CPU attached thereto identify that the task “Connect Disposables” has been identified.

[0061] In step 136 , the medical device is informed that the task “connect disposables” has been identified.

[0062] In step 138 , the medical device is prepared for functional testing.

[0063] In step 140, the user then installs the pipeline.

[0064] In step 142 , the AR device identifies that a line has been connected, and may additionally or alternatively check for improperly connected lines.

[0065] In step 144, the medical device is notified that the disposable has been installed.

[0066] In step 146 , the medical device performs a functional test of the line.

[0067] In step 148 , the medical device notifies the AR device of a positive test or result.

[0068] In step 150, the result is displayed in the AR device. If the result is negative, the steps of step 142 are repeated.

[0069] If everything goes well, then in step 152 , the next step is displayed in the AR device.
