[3. Specific example of setting contents]
FIG. 3 is a diagram showing an example of the display screen of the display 223. As shown in FIG. Screen 30 in FIG. 3 represents an example of setting information for dialysis treatment. CPU 211 can display screen 30 on display 223 using a variety of information including the items written in the chart and the output from weight sensor 330 .

Screen 30 includes items "Taro Yamada" and "DW: 65.0 kg". These items are an example of the items described in the chart of the person identified as the patient 901 . “Taro Yamada” represents the name of the patient 901 . DW (dry weight) represents body weight when the body is properly hydrated.

The screen 30 includes an item "previous weight: 68.0 kg". This item represents the result of measurement by the weight sensor 330 before starting the current dialysis treatment.

The screen 30 includes an item "Increase: 3.0 kg". This item is a value obtained by subtracting "DW" from "previous weight".

The screen 30 includes an item "additional amount: 0.20 kg". This item is the amount of replacement fluid and meals during dialysis, and indicates the amount to be added in advance to the "water removal amount" which is an example of the setting information. In one implementation, the CPU 211 generates setting information such that the weight of the patient 901 is reduced by the weight derived as the sum of the "increase amount" and the "addition amount" in the current dialysis treatment. In the example of FIG. 3, the setting information is generated so that the weight of the patient 901 is reduced by 3.20 kg (3.0 kg+0.20 kg). That is, the setting information includes the "water removal amount", and the "water removal amount" is derived as the sum of the "increase amount" and the "addition amount".

Screen 30 includes an OK button 31 . In one implementation, the patient 901 may view what is displayed (eg, name) on the screen 30 , confirm that it is the patient's 901 information, and operate the OK button 31 .

In the example of FIG. 4, the pop-up 41 contains the string "Fever: Please consult a doctor at the time of examination." This character string can be displayed based on CPU 211 detecting that the temperature of patient 901 measured by thermography camera 320 is higher than the reference range.

[4. Process flow]
FIG. 5 is a flowchart of processing executed by the management device 200 to generate setting information. The processing in FIG. 5 may be performed by the CPU 211 (processor) executing a given program, or may be performed by a dedicated electric circuit such as an ASIC (Application Specific Integrated Circuit) in the management device 200. .

In step S10, the management device 200 acquires the patient's biological information. An example of biometric information is an image output from visible light camera 310 .

In step S12, the management device 200 authenticates the patient by comparing the biometric information acquired in step S10 with the authentication information.

In step S20, management device 200 determines whether or not the patient has been successfully authenticated in step S12. In one implementation, authentication is determined to be successful if the authentication information includes information that matches the biometric information obtained in step S10. If management device 200 determines that it has succeeded (YES in step S20), it advances control to step S40, and if it determines that it has failed (NO in step S20), it advances control to step S30.

In step S30, management device 200 notifies an error and ends the processing of FIG. An example of notification is display on the display 223 .

At step S50, it is determined whether or not the physical information measured at step S40 is normal. In one example, the management device 200 determines that the physical information is normal if the current body weight increase/decrease value relative to the body weight at the end of the previous dialysis treatment is within a given range. In another example, the management device 200 determines that the physical information is normal if the patient's body temperature is within a range registered as normal. In yet another example, the management device 200 determines that the physical information is normal if the patient's blood pressure is within a range registered as normal.

If management device 200 determines that the physical information is normal (YES in step S50), control proceeds to step S70, otherwise (NO in step S50), control proceeds to step S60. When there is a plurality of pieces of physical information and the management device 200 determines that the physical information is not normal for at least one item, the control may proceed to step S60.

In step S60, management device 200 generates alert information. Alert information is information for notifying physical information determined to be abnormal in step S50, for example, information for displaying pop-up 41 in FIG.

In step S70, management device 200 generates setting information for dialysis treatment. At least the patient's chart authenticated in step S12 and the patient's weight measured in step S40 are used to generate the setting information.

In step S80, management device 200 displays the setting information generated in step S70 on display 223, and terminates the processing of FIG. If alert information has been generated in step S60, the alert information is displayed on display 2223 in addition to the setting information in step S80. An example of a display that includes alert information is screen 40, and an example of a display that does not include alert information is screen 30. FIG.

The doctor can then confirm the setting information displayed on the display 223 and enter the given information into the management device 200 . Thereby, the management device 200 can transfer the setting information to the controller 340 . Thereby, the dialysis machine connected to the controller 340 can implement dialysis treatment according to the setting information.

The management device 200 may further transfer the setting information to the controller 340 on the condition that the OK button 31 is operated by the patient. Thereby, the setting information displayed on the display 223 can be transferred to the controller 340 after being confirmed not only by the doctor but also by the patient.

Management device 200 and visible light camera 310 are arranged near weight sensor 330 so that the patient whose weight is measured by weight sensor 330 can easily check the display on display 223 and operate OK button 31 . may Thereby, the patient's face image photographing and weight measurement can be performed at the same position. Furthermore, the patient can confirm the display on the display 223 at the location where the imaging and measurement were performed.
