In step S2, the output unit 25 outputs a question about the physical symptom to the user detected by the detection unit 26. Specifically, the speaker as the output unit 25 outputs the question by voice.

In the present embodiment, the control unit 21 identifies the user detected by the detection unit 26. As the identification method, the image obtained by the optical sensor as the detection unit 26, the voiceprint obtained by the sound sensor as the detection unit 26, or the impedance or body composition value obtained by the conductive sensor as the detection unit 26 is used. Any method such as an analysis method can be used.

The control unit 21 acquires the attribute value of the identified user. The attribute value may be stored in the storage unit 22 in advance, or may be received from the terminal 12 or the server 30 via the communication unit 23. The control unit 21 adjusts the question according to the acquired attribute value. Specifically, the control unit 21 acquires a value indicating the disease of the identified user as an attribute value of the identified user. The control unit 21 changes the content of the question depending on the disease. For example, if the disease is heart failure, the control unit 21 causes the output unit 25 to output a question about findings suspected to be congested. If the disease is diabetes, the control unit 21 causes the output unit 25 to output a question about findings suspected to be hyperglycemia or hypoglycemia. The attribute value is not limited to a value indicating a disease, but may be a value indicating gender, age, race, nationality, region, awareness, or the presence or absence of a caregiver. The question item or text may be specified by the medical institution. For example, the question may use a dialect, or the same language used in discharge education may be used.

In step S3, the input unit 24 accepts an operation of inputting an answer to the question output from the output unit 25 as an input operation of the user's physical symptom detected by the detection unit 26. Specifically, the microphone as the input unit 24 accepts an operation of inputting an answer by voice as an input operation of a physical symptom.

In step S4 and step S5, the control unit 21 records the physical symptom of the user in response to the input operation to the input unit 24. Specifically, in step S4, the control unit 21 identifies the physical symptom by analyzing the answer input to the input unit 24. For example, if the symptom is answered "yes" or "no", a false value is returned. If the symptom is answered on a scale such as "1", "2", or "3", a scale such as "1", "2", or "3" is returned. If the symptom is answered in natural language, a false value or a scale such as "1", "2", or "3" is returned. In step S5, the control unit 21 records the physical symptom by storing the specified physical symptom in the storage unit 22. Alternatively, the control unit 21 records the physical symptom on the terminal 12 by transmitting data indicating the specified physical symptom to the terminal 12 via the communication unit 23. Alternatively, the control unit 21 records the physical symptom on the server 30 by transmitting data indicating the specified physical symptom to the server 30 via the communication unit 23.

If the confirmation of all physical symptoms has not been completed in step S6, the processes of steps S2 to S5 are performed again. If all physical symptoms have been confirmed, the flow ends.

As described above, in the present embodiment, the detection unit 26 of the symptom recording device 20 detects the user on the weight scale 11. The input unit 24 of the symptom recording device 20 receives an input operation of the physical symptom of the user by the user detected by the detection unit 26. The control unit 21 of the symptom recording device 20 records the physical symptom of the user in response to the input operation to the input unit 24.

As a modification of this embodiment, in step S3, instead of the microphone as the input unit 24 accepting the input operation, the button or slider as the input unit 24 may accept the input operation. For example, for a symptom, the button corresponding to "yes" or "no" may be pressed, or the button corresponding to the scale such as "1", "2", or "3" may be pressed. .. Alternatively, for symptoms, the slider may be moved to a position corresponding to "yes" or "no", or moved to a position corresponding to a scale such as "1", "2", or "3". May be done.

As a modification of this embodiment, in step S1, the detection unit 26 may observe the user's body part. Specifically, the optical sensor as the detection unit 26 may observe the user's foot or the user's nape. In that case, in step S4 and step S5, the control unit 21 records the physical symptom according to the result of the observation by the detection unit 26. Specifically, the control unit 21 analyzes the image of the foot obtained by the optical sensor as the detection unit 26 to confirm the presence or absence of edema. Alternatively, the control unit 21 analyzes the image of the nape of the neck obtained by the optical sensor as the detection unit 26 to confirm the jugular vein distension.

As a modification of this embodiment, in step S2, the control unit 21 may acquire the measured value of the weight scale 11 and adjust the question according to the acquired measured value. That is, the control unit 21 may change the content of the question according to the measured value of the weight scale 11. For example, the control unit 21 may cause the output unit 25 to output a more detailed question about the congestive findings if the body weight is rapidly increasing. The control unit 21 does not have to cause the output unit 25 to output a question about the congestive findings if the body weight is not gained.

As a modification of this embodiment, in step S3, the control unit 21 changes the question depending on the answer input to the input unit 24, returns to step S2, and outputs the changed question to the output unit 25. You may let me. That is, the control unit 21 may change the content of the question depending on the answer or the response time. For example, when the control unit 21 returns the answer "I don't know" to the question "Is there edema of the lower leg?", The question is expressed more simply as "Is there swelling in the legs?" You may change it to.

As a modification of this embodiment, in step S2, the output unit 25 may further output a question regarding the body weight to the user detected by the detection unit 26. In that case, in step S3, the input unit 24 accepts an operation of inputting the measured value of the weight scale 11 by the user detected by the detection unit 26. For example, weight may be answered numerically or in natural language. The control unit 21 acquires the measured value input to the input unit 24. In step S5, the control unit 21 may record the acquired measured value together with the physical symptom. According to this modification, since the symptom recording device 20 does not have to communicate with the weight scale 11, an analog weight scale can be used as the weight scale 11.

As a modification of this embodiment, when an error occurs in the analysis of step S4, the question in step S2 may be repeated, or the user may be explained that the error has occurred. When the physical symptom is out of the set range, the alert may be notified to the user, the user's family, a third party such as a caregiver, or a medical institution such as a hospital. If the weight is not measured, the alert may be notified to the user, the user's family, a third party such as a caregiver, or a medical institution such as a hospital. If the error is not corrected, an alert may be sent to the user, the user's family, a third party such as a caregiver, or a medical institution such as a hospital.

The present disclosure is not limited to the above-described embodiment. For example, a plurality of blocks described in the block diagram may be integrated, or one block may be divided. Instead of executing the plurality of steps described in the flowchart in chronological order according to the description, they may be executed in parallel or in a different order according to the processing capacity of the device that executes each step, or as necessary. Other changes are possible without departing from the spirit of this disclosure.
