A display control unit 66 and the like are included.

The measurement data acquisition unit 61 has a function of acquiring measurement data including blood pressure data measured by the wearable device 2. Further, the measurement data acquisition unit 61 may acquire information measured by the CPAP device 3. The control unit 41 receives the measurement data acquired from the wearable device 2 or the CPAP device 3 via the user terminal 11 by the communication unit 43 as the measurement data acquisition unit 61 and stores the received measurement data in the storage unit 42. For example, the control unit 41 acquires measurement data transferred from the wearable device 2 via the user terminal 11.

The blood pressure fluctuation detection unit 62 has a function of detecting blood pressure fluctuations equal to or higher than a reference value for determining a blood pressure surge from the continuously measured blood pressure data. The blood pressure surge is defined by a preset reference value. For example, a blood pressure change of 20 mmHg or more during 30 beats is defined as a surge (blood pressure surge). Control part 41 performs processing which detects blood pressure fluctuation more than the standard value judged as a blood pressure surge from blood pressure data measured continuously over the measurement period as blood pressure fluctuation detection part 62.

The risk determination unit 63 has a function of determining the risk of causing the onset of a brain / cardiovascular disease. This degree of risk is determined based on various factors including a blood pressure surge. For example, people who have factors that may cause cerebrovascular and cardiovascular disease other than blood pressure and those who do not have the same risk level even if the number and magnitude of blood pressure surges are the same. It is done. For this reason, the determination of the risk level is made based on a criterion set according to the risk level of each user, taking into account factors other than the user's own blood pressure. However, in the present embodiment, the risk level determination unit 63 will be described with reference to an example in which the risk level for the detected blood pressure surge is determined.
In addition, as an example, a case where the degree of risk is determined based on a reference value set in a plurality of stages with respect to a blood pressure change (blood pressure surge) will be described. In this example, a blood pressure change of 20 mmHg or more during 30 beats is defined as a surge (blood pressure surge). Furthermore, blood pressure changes of less than 20 mmHg during 30 beats are normal values, blood pressure changes of 20 mmHg to less than 40 mmHg are considered low risk surges during 30 beats, and blood pressure changes of between 40 mmHg and less than 60 mmHg are moderately dangerous during 30 beats. A surge is defined as a blood pressure change of 60 mmHg or more during 30 beats as a super-danger surge. In such an example, the control unit 41 determines the risk level as the risk level determination unit 63 based on a preset reference value.

It should be noted that the criteria for determining the definition of blood pressure surge and the degree of risk are information that should be appropriately set based on medical viewpoints and operational viewpoints, and are not limited to specific reference values. For example, in the present embodiment, a description will be given on the assumption that a blood pressure surge at a plurality of stages of risk is detected as a blood pressure fluctuation equal to or greater than a reference value. However, an adjustment ability for returning an increased blood pressure value to a normal value is detected as a blood pressure fluctuation. Anyway.

The aggregation processing unit 64 is a function that aggregates blood pressure data measured by the wearable device 2 and generates aggregate data. How to collect blood pressure data is set according to the display content to be displayed on the display unit 25 of the wearable device 2. For example, the control unit 41 aggregates the maximum blood pressure, the number of occurrences of blood pressure surge during sleep (during monitoring) (sleep surge), the detected risk level of blood pressure surge, and the like as the aggregation processing unit 64.

The aggregate data output unit 65 is a function for outputting aggregate data. The control unit 41 transmits, as the total data output unit 65, the total data obtained by totaling the measurement data by the total processing unit 64 to the wearable device 2 that is the transmission source of the measurement data.

The terminal display control unit 66 is a function for controlling display contents displayed on the user terminal 11. The control unit 41 supplies, as the terminal display control unit 66, display data generated from the measurement data accumulated in the storage unit or the like in accordance with the display request from the user terminal 11 and the total data to the user terminal 11 of the user.

Next, the operation of the system configured as described above will be described.
The user (measured person) instructs the continuous measurement (monitoring) of the blood pressure value at bedtime by operating the wearable device 2. The wearable device 2 starts continuous measurement of blood pressure values in response to monitoring instructions. The wearable device 2 monitors the user's getting up while sleeping (during monitoring). When detecting the user's wake-up, the wearable device 2 ends the monitoring and displays information indicating the monitoring result on the display unit. The information indicating the monitoring result displayed on the display unit when waking up is information (aggregated data including the degree of risk) generated by the server 12 from the measurement data (sleeping blood pressure data).

FIG. 7 is a flowchart for explaining a first operation example of the wearable device 2 according to the present embodiment.
The user (measured person) instructs the continuous measurement (monitoring) of the blood pressure value at bedtime by operating the wearable device 2. The control unit 21 of the wearable device 2 receives various operation instructions by the function of the operation detection unit 51.

When it is detected that monitoring is instructed (S11, YES), the control unit 21 starts the continuous measurement of the blood pressure value for the measurement subject using the blood pressure sensor 27a by the function of the measurement control unit 55 (S12). After starting the continuous measurement of the blood pressure value, the control unit 21 performs the continuous measurement of the blood pressure value using the blood pressure sensor 27a by the function of the measurement control unit 55 (S13). In the continuous measurement of the blood pressure value, the control unit 21 accumulates the measured blood pressure value (blood pressure data) in the storage unit 23. The control unit 21 transfers the blood pressure data accumulated in the storage unit 23 to the server 12 via the user terminal 11 or the user terminal 11 at the end of measurement.

However, the control unit 21 may transfer the blood pressure data stored in the storage unit 23 to the server 12 via the user terminal 11 or the user terminal 11 at a predetermined cycle. The control unit 21 may transfer the blood pressure data to the server 12 via the user terminal 11 or the user terminal 11 without saving the blood pressure data in the storage unit 23. The timing for transferring the blood pressure data to the user terminal 11 or the server 12 depends on the storage capacity of the storage unit 23 in the wearable device 2, the timing of the data processing by the server 12 or the user terminal 11 for the blood pressure data, or the communication environment. It is set appropriately.

During execution of continuous measurement of blood pressure values, the control unit 21 monitors (detects) the measurement subject's wake-up by the function of the wake-up determination unit 56. For example, the control unit 21 detects that the measurement subject has woken up by the movement of the measurement subject detected by the acceleration sensor 29. Moreover, you may make it the control part 21 detect a wake-up according to operation by a to-be-measured person. If the wake-up of the measurement subject is not detected (S14, NO), the control unit 21 returns to S13 and continuously performs the continuous measurement of the blood pressure value for the measurement subject.

When the measurement subject's wake-up is detected (S14, YES), the control unit 21 indicates that the measurement subject has woken up and blood pressure data associated with identification information for identifying the measurement subject or the wearable device (continuously measured blood pressure). The measurement data including the value is transferred to the server 12 via the user terminal 11 (S15). On the other hand, the server 12 aggregates measurement data including blood pressure data by a process described later (for example, the processes of S31 to S35 in FIG. 9), and transmits the aggregated data as the aggregation result to the wearable device 2.

The control unit 21 of the wearable device 2 transmits the measurement data to the server 12 when getting up, and then acquires the aggregate data supplied from the server 12 (S16). Here, it is assumed that the aggregated data acquired from the server 12 includes information indicating the maximum blood pressure value, the number of blood pressure surges, the degree of risk, and the like.

When the total data is acquired from the server 12, the control unit 21 causes the vibration unit 26 to vibrate the casing (main body) by the function of the vibration control unit 53 (S17). Further, the control unit 21 displays the risk level on the display 25a by the function of the risk level display unit 54 (S18). For example, the control unit 21 specifies a risk level for the monitoring result (blood pressure value continuously measured during sleep) based on information included in the aggregated data acquired from the server 12, and uses a color corresponding to the specified risk level. The display 25a is displayed.

Thereby, the wearable device 2 displays the degree of danger to the measurement result while vibrating the casing (main body) when getting up. As a result, the person to be measured recognizes that the total data has been obtained by vibration when getting up, and can intuitively visually recognize the degree of risk with respect to the measurement results displayed by color.

Also, the control unit 21 causes the display unit 25 to display aggregate data for the measurement result in accordance with the operation by the measurement subject. That is, the control unit 21 receives an instruction to display the total data from the measurement subject in a state where the risk level is displayed by vibrating the main body (housing) (S19). When receiving the display instruction of the total data (S19, YES), the control unit 21 displays the total data on the display unit 25 according to the operation by the measurement subject (S20). Moreover, the control part 21 complete | finishes a series of operation | movement, when display end is instruct | indicated (S21, YES).

FIG. 8 is a diagram illustrating an example of a display screen displayed by the display unit 25 of the wearable device 2 in accordance with the above-described operation.
A display screen 80 shown in FIG. 8 is an example of an initial screen that is displayed first when waking up. On the display screen (display state) 80, the display 25a displays a color corresponding to the degree of danger, and no specific information is displayed on the display unit 25. In the display screen 80, it is assumed that the main body of the wearable device 2 is vibrated by the vibration unit 26. The initial screen displayed when you wake up may display a message indicating that the measurement has been completed, such as “measurement during sleep (monitoring) completed”, or a wake-up such as “Good morning” will be detected. You may display the message which shows that it was carried out.

The display screen 81 is a first example of a measurement result display screen that is displayed in response to an instruction to display aggregated data (measurement results) by the measurement subject. In the display screen 81 shown in FIG. 8, the maximum blood pressure value is displayed as one of the measurement results. An instruction to display the measurement result may be received by input to the touch panel as the operation unit 24 or may be received according to the movement of the measurement subject. Upon receiving the measurement result display instruction, the control unit 21 displays a display screen 81 on the display unit 25. For example, as a function of the operation detection unit 51, the control unit 21 can detect an operation in which the main body (housing) of the wearable device 2 is shaken in a specific direction by the acceleration sensor 29. In this case, the control unit 21 may accept the movement of the main body in a specific direction as a measurement result display instruction.

The display screen 82 is a second example of a measurement result display screen displayed as a next screen on the display screen 81. In the display screen 82 shown in FIG. 8, as the next screen of the display screen 81, the number of blood pressure surges (sleep surges) during sleep is displayed as one of the measurement results.
The display screen 83 is a third example of a measurement result display screen displayed as the next screen of the display screen 82. In the display screen 83 shown in FIG. 8, information indicating the risk level based on the blood pressure surge detected from the measurement data and a comment corresponding to the risk level are displayed as the next screen of the display screen 82.

For example, the control unit 21 switches the display screens 81, 82, and 83 that display the measurement results as the next screen or the previous screen in response to a swipe (touch operation that moves horizontally on the screen) of the touch panel as the operation unit 24. . Further, the control unit 21 may detect a motion that can be detected by the acceleration sensor 29 as a switching instruction for the display screens 81, 82, and 83.

Next, the operation of the server 12 will be described.
FIG. 9 is a flowchart for explaining an operation example of the server 12.
The control unit 21 of the server 12 receives the measurement result (measurement data) of the continuous measurement (monitoring) of the blood pressure value at bedtime transferred from the wearable device 2 via the user terminal 11 by the function of the measurement data acquisition unit 61. ing. When measurement data is received from a certain wearable device 2 (S31), the control unit 41 stores the received measurement data in the storage unit 42 in association with the identification information of the person being measured or the identification information of the wearable device 2 (S32). .

Further, when the measurement data is received, the control unit 41 detects a blood pressure fluctuation (blood pressure surge) equal to or higher than the reference value from the blood pressure data included in the received measurement data by the function of the blood pressure fluctuation detection unit 62 (S33). When the blood pressure surge is detected, the control unit 41 determines the risk level for the detected blood pressure surge by the function of the risk level determination unit 63 (S34). Further, the control unit 41 aggregates various data including the blood pressure surge obtained from the measurement data and the risk of the blood pressure surge by the function of the aggregation processing unit 64, and generates aggregate data (S35).

When generating the aggregated data from the received measurement data, the control unit 41 transmits the generated aggregated data to the wearable device 2 that is the transmission source of the measurement data by the function of the aggregated data output unit 65 (S36). Further, the control unit 41 stores the generated aggregate data in the storage unit 42 in association with the measurement data and the identification information of the measurement subject or the identification information of the wearable device 2.

Further, the control unit 41 determines whether to display the aggregated data on the user terminal 11 of the measurement subject (S37). For example, the control unit 41 determines whether or not to perform display on the user terminal 11 according to the setting by each user (measured person). When it is determined to be displayed on the user terminal 11 (S37, YES), the control unit 41 uses the function of the terminal display control unit 66 to display detailed data based on the total data and measurement data to be displayed on the user terminal 11. Is generated (S38).

The display data of the detailed information displayed on the user terminal 11 includes information for confirming the total data and the measurement data in detail. Further, the display data of the detailed information may include an evaluation comment for evaluating the total data. The evaluation comment may be generated by the control unit 41 based on a comparison result with past measurement data or standard data of the measurement subject. When such detailed information display data is generated, the control unit 41 transmits the generated detailed information display data to the user terminal 11 (S39). Note that the display data of the detailed information to be displayed on the user terminal 11 may be generated after receiving a request from the user terminal 11.

FIG. 10 is a diagram illustrating an example of a display screen displayed by the display unit 34 of the user terminal 11.
FIG. 10A shows a display screen 101 displayed on the display unit 34 of the user terminal 11 when getting up. The display screen 101 is displayed on the display unit 34 based on receiving display data of detailed information generated based on the measurement data acquired by the server 12 from the wearable device 2 when the user wakes up. That is, when the user wakes up, the control unit 31 of the user terminal 11 receives detailed information display data from the server 12 and displays the display screen 101 on the display unit 34. The display data of the detailed information acquired from the server 12 is held in the storage unit 32, for example. The display screen 101 is a screen that displays that detailed information can be displayed, and the message display part 101a functions as a button that instructs to display the detailed information.

When the message display part 101 a on the display screen 101 is touched, the control unit 31 of the user terminal 11 displays the display data of the detailed information acquired from the server 12 on the display unit 34. A display screen 102 in FIG. 10B is an example in which display data of detailed information acquired from the server 12 is displayed. On the display screen 102, evaluation comments on the measurement data, risk level, maximum blood pressure, number of occurrences of surge during sleep (sleep surge frequency), sleep time, calendar, and the like are displayed as detailed information.

The control unit 31 of the user terminal 11 may display the display screen 101 upon receiving a wake-up notification from the wearable device 2. That is, the control unit 31 of the user terminal 11 may display the display screen 101 on the display unit 34 when receiving a notification from the wearable device 2 indicating that waking up has been detected. In this case, when the display part 101a of the message on the display screen 101 is touched, the control unit 31 of the user terminal 11 requests display data of detailed information from the server 12, and the server 12 transmits in response to this request. The display data of the detailed information to be displayed may be displayed on the display unit 34.

Next, a second operation example by the wearable device 2 will be described.
FIG. 11 is a flowchart for explaining a second operation example by the wearable device 2.
In the second operation example, when the degree of risk determined from the measurement data is equal to or higher than a predetermined value, an alert at the time of waking up (display of vibration and risk level) is performed, and when the degree of risk is lower than the predetermined value, It is an operation example in which an alert is not performed.

Here, the processing of S51 to S56 shown in FIG. 11 can be realized by the same operation as the processing of S11 to S16 shown in FIG. Further, the processing of S58 to S62 shown in FIG. 11 can be realized by the same operation as the processing of S17 to S21 shown in FIG. For this reason, in the description of the second operation example, detailed description of the processing of S51-S56 and S58-S62 shown in FIG. 11 is omitted.

That is, in the second operation example, when the total data for the measurement data is acquired from the server 12 when getting up, the control unit 21 of the wearable device 2 has a risk level included in the total data acquired from the server 12 equal to or higher than a predetermined value. It is determined whether there is (S57).
When it is determined that the degree of risk is less than the predetermined value (S57, NO), the control unit 21 ends the series of processes without performing an alert (display of the vibration of the casing and the degree of risk) for the measurement subject. .

When it is determined that the degree of risk is equal to or greater than the predetermined value (S57, YES), the control unit 21 vibrates the housing (main body) with the vibration unit 26 by the function of the vibration control unit 53 (S58), and the risk level display unit. The color corresponding to the degree of danger is displayed (lighted) on the display 25a by the function 54 (S59). For example, when the degree of risk included in the aggregated data acquired from the server 12 is “super dangerous”, the control unit 21 vibrates the housing and causes the display 25a to emit light in red.

According to the second operation example described above, the wearable device 2 alerts the measurement result to the person to be measured when getting up if the degree of risk determined from the measurement result is a predetermined value or more, and is determined from the measurement result. If the risk level is less than a predetermined value, the alert to the measurement subject at the time of getting up is not performed.

As a result, the measured person can confirm the measurement result by an alert at the time of waking up when the blood pressure value continuously measured during sleep is determined to be dangerous, and continuously measured during sleep. If the blood pressure value is not in a dangerous state, an alert or the like can be prevented.

As described above, the wearable device as the blood pressure measurement device according to the present embodiment performs the continuous measurement of the blood pressure value in the sleep of the measurement subject using the blood pressure sensor capable of continuously measuring the blood pressure value. When the blood pressure measurement device detects that the measurement subject wakes up during the continuous measurement of the blood pressure value during sleep, the blood pressure measurement device displays information indicating the measurement result of the continuous measurement of the blood pressure value on the display unit.
Thereby, the measurement subject who has measured the blood pressure while sleeping by the blood pressure measurement device can easily confirm the measurement result when waking up without performing a specific operation instruction. As a result, the person to be measured can make a daily action plan according to blood pressure data at bedtime, which can be used for health maintenance.

The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment.
