Japanese Patent Application Laid-Open No. 2015-77229

However, the biological data measured in a state where the subject wears the measuring device improperly has low reliability. Therefore, it is preferable that the biometric data be measured in a state where the subject wears the measuring device in an appropriate state.

Patent Document 1 discloses a technique for detecting whether or not a cuff is worn on a subject based on the amount of extension of the cuff in the circumferential direction. However, according to the technique disclosed in Patent Literature 1, it is not possible to determine whether the subject is properly or inappropriately wearing the measuring device. Therefore, it is difficult to evaluate the reliability of biometric data using the technique disclosed in Patent Document 1.

目的 An object of the present invention is to pay attention to the above circumstances, and to provide a technique for evaluating the reliability of biometric data.

A first aspect of the present disclosure is directed to a first measurement unit that measures first biological data of a subject, and a second biological data of the subject within a predetermined period including a measurement date and time of the first biological data. A second measurement unit that measures data, and a first determination unit that determines whether the wearing state of the second measurement unit by the subject is appropriate or inappropriate based on the first biological data, A biometric data measurement device comprising: a second determination unit configured to determine whether the reliability of the second biometric data is high or low in accordance with a determination result indicating whether the mounting state is appropriate or inappropriate. .
For example, there is biometric data that not only changes according to the mounting state of the measurement unit included in the biometric data measurement device by the subject, but also reacts sensitively to abnormal body changes. On the other hand, there are biometric data that not only vary according to the state of attachment of the measurement unit included in the biometric data measurement device by the subject, but also do not react so much in the resting state if the abnormality that occurs on the body is mild. The former biometric data is susceptible to abnormalities in the subject's body. For this reason, the former biometric data is not suitable for evaluating whether the mounting state of the measurement unit for measuring the former biometric data included in the biometric data measurement device by the subject is appropriate or inappropriate. The latter biometric data is not frequently affected by abnormalities in the subject's body. Therefore, the latter biometric data is suitable for evaluating whether the mounting state of the measurement unit for measuring the latter biometric data included in the biometric data measurement device by the subject is appropriate or inappropriate. In addition, when the biological data measuring device includes two measuring units that measure different biological data, if the mounting state of one measuring unit by the subject is appropriate, the mounting state of the other measuring unit by the subject is also appropriate. Probably. On the other hand, if the mounting state of one measurement unit by the subject is inappropriate, it is highly likely that the mounting state of the other measurement unit by the subject is also inappropriate. The biometric data measurement device uses the latter biometric data as first biometric data and the former biometric data as second biometric data. Accordingly, the biological data measurement device cannot directly determine whether the measurement unit that measures the second biological data by the subject is appropriate or inappropriate based on the second biological data. Also, it is possible to indirectly determine whether the mounting state of the measurement unit that measures the second biological data by the subject is appropriate or inappropriate based on the first biological data. As a result, even if it is difficult for the biometric data measurement device to directly evaluate the reliability of the second biometric data based on the second biometric data, the biometric data measurement device may indirectly evaluate the second biometric data based on the first biometric data. Can be evaluated for the reliability of the biological data.

The biological data measurement device can accurately determine whether the subject is properly or inappropriately wearing the first measurement unit by using the reference data. Can be determined with high accuracy as to whether it is appropriate or inappropriate.

According to a third aspect of the present disclosure, in the first aspect, the first measurement unit measures data related to the subject's electrocardiogram as the first biological data, and the second measurement unit , Data relating to the blood pressure of the subject is measured as the second biological data.
Since the electrocardiographic data is not frequently affected by abnormalities of the subject's body, the electrocardiographic data is suitable for evaluating whether the subject is properly or inappropriately wearing the first measurement unit. Since the blood pressure data is easily affected by abnormalities of the subject's body, it is not suitable for the subject to evaluate whether the second measurement unit is properly or inappropriately mounted. The biological data measurement device can determine whether the second measurement section is properly or inappropriately worn by the subject based on the blood pressure data, even if the subject cannot directly determine whether the second measurement unit is properly mounted. It is possible to indirectly determine whether the mounting state of the second measuring unit is appropriate or inappropriate. Even if it is difficult to directly evaluate the reliability of blood pressure data based on blood pressure data, the biological data measurement device can indirectly evaluate the reliability of blood pressure data based on electrocardiographic data.

And a signal output unit that outputs a signal instructing execution of support for improving the above.
The biological data measurement device can measure highly reliable second biological data by supporting the improvement of the state of attachment of the second measurement unit to the subject.

The biometric data measurement device can assist a doctor in making a diagnosis by providing the doctor with the second biometric data associated with the reliability data. By confirming the reliability of the second biometric data, the doctor can easily determine whether or not to use the second biometric data for the examination of the subject.

A sixth aspect of the present disclosure is directed to a first measurement unit that measures first biological data of a subject in a first measurement unit included in the biological data measurement device, and a first measurement process that is included in the biological data measurement device. In the second measurement unit, based on the second measurement process of measuring the second biometric data of the subject within a predetermined period including the measurement date and time of the first biometric data, based on the first biometric data, A first determination step of determining whether the mounting state of the second measurement unit by the subject is appropriate or inappropriate; and a determination result indicating whether the mounting state is appropriate or inappropriate. A second determining step of determining whether the reliability of the second biometric data is high or low.

Hereinafter, the same or similar elements as those already described are denoted by the same or similar reference numerals, and duplicate description will be basically omitted.

§1 Application example
The present embodiment is a technique for evaluating the reliability of biometric data and associating data related to the reliability with the biometric data.
FIG. 1 is a diagram schematically illustrating an application example of the measuring device A1.
The measuring device A1 includes an electrocardiographic measuring unit A11 and a blood pressure measuring unit A12. The electrocardiogram measurement unit A11 measures the electrocardiogram of a subject wearing the measurement device A1. The blood pressure measurement unit A12 measures the blood pressure of the subject wearing the measurement device A1. In a typical example, the blood pressure measurement unit A12 measures the blood pressure of the subject within a predetermined period including the date and time of measuring the electrocardiogram.

The measuring device A1 acquires reference data from an EHR (Electronic Health Records) server A3 via the mobile terminal A2. The reference data is data used to determine whether the subject's wearing state of the electrocardiographic measurement unit A11 is appropriate or inappropriate. The measurement device A1 determines whether the subject's wearing state of the electrocardiogram measurement unit A11 is appropriate or inappropriate based on the electrocardiogram data and the reference data. The measurement device A1 determines whether the subject's wearing state of the blood pressure measuring unit A12 is appropriate or inappropriate depending on whether the subject's wearing state of the electrocardiographic measurement unit A11 is appropriate or inappropriate.

測定 Thus, the measurement device A1 can evaluate the reliability of the biological data.

§2 Configuration example
<Biometric data management system>
FIG. 2 is a diagram illustrating an overall configuration of the biometric data management system 100. The biometric data management system 100 is a system for managing biometric data of each person.
The biological data management system 100 includes a measurement device 1, a mobile terminal 2, a PHR server 3, and an EHR server 4. The mobile terminal 2, the PHR server 3, and the EHR server 4 can communicate with each other via a network. For example, the network is the Internet.

The measuring device 1 is a device that measures a physical quantity of a living body of a subject to which the measuring device 1 is worn. The measurement device 1 measures at least two different physical quantities. For example, the measuring device 1 measures an electrocardiogram and a blood pressure. The measurement device 1 measures biological data indicating a physical quantity of a living body of a subject. An example of the biometric data is data indicating an electrocardiogram. Data indicating an electrocardiogram is also referred to as electrocardiogram data. Note that the “electrocardiogram data” may be simply referred to as “electrocardiogram” and may be appropriately read. For example, the electrocardiogram data is waveform data indicating the fluctuation of the electrocardiogram during the measurement period. Instead, the electrocardiogram data may be data indicating a feature value of the electrocardiogram during the measurement period. For example, the feature value is a peak value, but is not limited thereto. The electrocardiogram may be a P wave, an R wave, or an S wave, and is not limited. Another example of the biometric data includes data indicating blood pressure. Data indicating blood pressure is also referred to as blood pressure data. Note that the “blood pressure data” may be simply referred to as “blood pressure” and may be appropriately replaced. For example, the blood pressure data is data indicating a value of systolic blood pressure SBP (Systolic Blood Pressure) and a value of diastolic blood pressure DBP (Diastatic Blood Pressure) at the time of blood pressure measurement. Instead, the blood pressure data may be waveform data indicating fluctuations in SBP and DBP during the measurement period. The measurement device 1 is also called a biological data measurement device.

The portable terminal 2 is a device that acquires electrocardiographic data and blood pressure data from the measuring device 1 and provides the electrocardiographic data and blood pressure data to the PHR server 3. For example, the mobile terminal 2 is a smartphone or a tablet, but is not limited thereto. The mobile terminal 2 is an example of a biometric data providing device.

The PHR server 3 is a server that manages the biometric data of each person measured by the measuring device 1. The PHR server 3 collects biometric data of each person from the mobile terminal 2. Instead, the PHR server 3 may directly collect the biometric data of each person from the measurement device 1. The doctor can utilize the biometric data managed by the PHR server 3 for each patient's examination.

The EHR server 4 is a server that manages data on medical examinations performed by doctors. The EHR server 4 manages data related to each patient's examination in cooperation with an electronic medical record input by a doctor using a PC (Personal Computer). Data related to the consultation is also referred to as consultation data.

The examination data includes reference data indicating the physical quantity of the living body of each person. The reference data is data used for determining whether the mounting state of the measuring unit included in the measuring device 1 by the subject is appropriate or inappropriate, as described later. The reference data is data indicating a physical quantity of a living body measured in a state where the subject appropriately wears the measurement unit included in the measurement device 1.

The examination data includes first predetermined reference data relating to the electrocardiogram of each person. As will be described later, the first reference data is data used for determining whether the subject is properly or inappropriately wearing a measurement unit for measuring an electrocardiogram included in the measurement device 1. The first reference data may include a plurality of reference data measured at different time zones. For example, the first reference data includes reference data based on the measurement at the morning time and reference data based on the measurement at the afternoon time. One reason is that the tendency of electrocardiographic data differs depending on the time of day. Alternatively, the first reference data may include a plurality of reference data measured in different states of the subject. For example, the first reference data includes reference data based on the measurement of the subject in a nervous state and reference data based on the measurement of the subject in a resting state. One reason is that the tendency of the electrocardiographic data differs depending on the condition of the subject. Note that the first reference data may include a plurality of reference data obtained by combining the time zone and the state of the subject. When the first reference data includes a plurality of reference data, the accuracy of the determination by the subject as to whether the measurement unit included in the measurement device 1 that measures the electrocardiogram is properly or inappropriately mounted is increased.

The consultation data includes second predetermined reference data relating to the blood pressure of each individual. As will be described later, the second reference data is data used to determine whether the subject is properly or inappropriately wearing the measurement unit that measures the blood pressure included in the measurement device 1. The second reference data may include a plurality of reference data measured at different time zones. For example, the second reference data includes reference data based on the measurement at the morning time and reference data based on the measurement at the afternoon time. One reason is that the tendency of the blood pressure data differs depending on the time of day. Alternatively, the second reference data may include a plurality of reference data measured in different states of the subject. For example, the second reference data includes reference data based on the measurement of the subject in a nervous state and reference data based on the measurement of the subject in a resting state. One reason is that the tendency of the blood pressure data differs depending on the state of the subject. Note that the second reference data may include a plurality of reference data obtained by combining the time zone and the state of the subject. Since the second reference data includes a plurality of reference data, the accuracy of the determination whether the measurement unit included in the measurement device 1 that measures the blood pressure included in the measurement device 1 is properly or inappropriately mounted is increased.

<Measuring device>
[Hardware configuration]
FIG. 3 is a block diagram illustrating a hardware configuration of the measurement device 1.
The measurement device 1 includes a processor 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a storage device 104, a communication interface 105, an input unit 106, a display unit 107, a voice output unit 108, and an electrocardiogram measurement unit 109. And a blood pressure measurement unit 110. Each element is electrically connected to each other. In FIG. 3, the communication interface is described as “communication I / F”.

The processor 101 controls each element of the measuring device 1. For example, the processor 101 is a CPU (Central Processing Unit), but is not limited thereto. The processor 101 loads a program for executing the measuring device 1 stored in the storage device 104 on the RAM 103. Then, the processor 101 can execute various operations by interpreting and executing the program developed in the RAM 103.

The storage device 104 is a so-called auxiliary storage device. For example, the storage device 104 is a semiconductor memory such as a built-in or external flash memory, but is not limited thereto. The storage device 104 stores a program executed by the processor 101. Note that the program may be stored in the storage device 104 in advance. The program may be downloaded to the measurement device 1 via a network. The program may be stored on a non-transitory computer-readable medium and distributed.
The storage device 104 stores a plurality of electrocardiogram data having different measurement dates and times (measurement timing) measured by an electrocardiogram measurement unit 109 described later. The storage device 104 stores a plurality of blood pressure data having different measurement dates and times measured by the blood pressure measurement unit 110 described later.

The communication interface 105 is an interface for communicatively connecting the measuring device 1 to another device. The communication interface 105 includes a short-range wireless communication module. The short-range wireless communication method is, for example, a communication method based on Bluetooth (registered trademark), but is not limited thereto. The communication interface 105 communicates directly with the mobile terminal 2 using a short-range wireless communication method. The communication interface 105 may include modules for various wireless communication schemes for mobile communication (3G, 4G, etc.), WLAN (Wireless Local Area Network), and the like. In this case, the communication interface 105 can communicate with the PHR server 3 and the EHR server 4 without passing through the mobile terminal 2.

The input unit 106 is a device that receives an instruction based on an input by the subject. For example, the input unit 106 includes a touch panel and operation keys, but is not limited thereto. The input unit 106 outputs a signal to the processor 101 according to an instruction given by the subject. In addition, the input unit 106 is not limited to a device that receives an instruction based on an input based on an operation of the target person, and may be a device that receives an instruction based on a voice of the target person.

The display unit 107 is a device that displays information. For example, the display unit 107 is a liquid crystal display, but is not limited to this.

The audio output unit 108 is a device that outputs audio. For example, the audio output unit 108 is a speaker, but is not limited to this.

The electrocardiogram measurement unit 109 is a device that measures the electrocardiogram of a subject to which the measurement device 1 is worn. For example, the electrocardiograph 109 includes two electrodes. The electrocardiogram measurement unit 109 measures the electrocardiogram of the subject based on a potential difference generated between the two electrodes according to the contact of the subject with the two electrodes. For example, the electrocardiogram measurement unit 109 measures the electrocardiogram of the subject while the subject is in contact with the two electrodes. The electrocardiogram measurement unit 109 stores the electrocardiogram data in the storage device 104 every time the electrocardiogram is measured. The electrocardiogram data includes data indicating the measurement date and time of the electrocardiogram. The measurement date and time of the electrocardiogram is detected by a clock function mounted on the measurement device 1. The electrocardiogram measurement unit 109 is an example of a first measurement unit.

The blood pressure measurement unit 110 is a device that measures the blood pressure of the subject wearing the measurement device 1. In a typical example, the blood pressure of the subject is measured within a predetermined period including the date and time of measuring the electrocardiogram. For example, the blood pressure measurement unit 110 includes a cuff, a pump, and a pressure sensor. The cuff is formed in a band shape that can be worn around the measurement site of the subject whose blood pressure is to be measured. The cuff has a bladder. The pump supplies air to the interior of the bladder to inflate the bladder. The pressure sensor measures the pressure in the bladder. Blood pressure measurement section 110 measures blood pressure based on data measured by the pressure sensor. The blood pressure measurement unit 110 is an example of a second measurement unit.

The blood pressure measurement unit 110 stores the blood pressure data in the storage device 104 every time the blood pressure is measured. The blood pressure measurement unit 110 acquires the SBP value and the DBP value at the time of blood pressure measurement. Instead of this, the blood pressure measurement unit 110 may continuously measure the blood pressure of the subject at every beat, without depending on the blood pressure measurement instruction. The blood pressure measurement unit 110 acquires the SBP value and the DBP value during the blood pressure measurement period.

The blood pressure measurement unit 110 stores the blood pressure data in the storage device 104. The blood pressure data includes data indicating the date and time of measuring the blood pressure. The measurement date and time of the blood pressure is detected by a clock function mounted on the measuring device 1.

The blood pressure measurement section 110 may measure the blood pressure by a method other than the method of measuring the blood pressure based on the pressure described above. For example, the blood pressure measurement unit 110 may use an optical system, a radio wave system, or an ultrasonic system that applies light, radio waves, or ultrasonic waves to a blood vessel of a subject and measures blood pressure based on the reflected waves.

Regarding the specific hardware configuration of the measuring device 1, it is possible to appropriately omit, replace, and add components according to the embodiment. For example, the measurement device 1 may include a plurality of processors.

[Software Configuration]
FIG. 4 is a block diagram illustrating a software configuration of the measurement apparatus 1.
The processor 101 implements a first acquisition unit 1011, a second acquisition unit 1012, a third acquisition unit 1013, a first determination unit 1014, a second determination unit 1015, a data output unit 1016, and a signal output unit 1017. I do.

<1> The first acquisition unit 1011 will be described. The first obtaining unit 1011 obtains first biometric data of the subject as exemplified below. Here, the electrocardiogram data will be described as an example of the first biological data. The first obtaining unit 1011 obtains electrocardiographic data one by one from a plurality of electrocardiographic data of the subject stored in the storage device 104. The first acquisition unit 1011 outputs electrocardiogram data to the second acquisition unit 1012 and the first determination unit 1014.

<2> The second acquisition unit 1012 will be described. The second acquisition unit 1012 acquires the second biometric data of the subject measured within a predetermined period including the measurement date and time of the first biometric data, as exemplified below. Here, the blood pressure data will be described as an example of the second biological data. First, the second acquisition unit 1012 receives electrocardiogram data from the first acquisition unit 1011. Next, the second obtaining unit 1012 obtains data indicating the measurement date and time of the electrocardiogram from the electrocardiogram data. Next, the second acquisition unit 1012 acquires from the storage device 104 the blood pressure data of the subject measured within a predetermined period including the date and time of measuring the electrocardiogram. Second acquisition unit 1012 outputs the blood pressure data to second determination unit 1015 and data output unit 1016.

<3> The third acquisition unit 1013 will be described. The third obtaining unit 1013 obtains predetermined first reference data to be compared with electrocardiographic data, as exemplified below. First, the third acquisition unit 1013 outputs a request for the first reference data of the subject to the EHR server 4 via the communication interface 105. The third acquisition unit 1013 can output a request to the EHR server 4 at an arbitrary timing. The request includes identification information identifying the subject. Next, the third acquisition unit 1013 receives the first reference data from the EHR server 4 via the communication interface 105 as a response to the request. Third acquisition unit 1013 outputs the first reference data to first determination unit 1014.

The first determining unit 1014 will be described. The first determination unit 1014 indirectly determines, based on electrocardiographic data, whether the subject's wearing state of the blood pressure measurement unit 110 is appropriate or inappropriate, as exemplified below.

In one example, the first determination unit 1014 compares the electrocardiogram data with the first reference data, and indirectly performs the operation of the blood pressure measurement unit 110 based on a comparison result between the electrocardiogram data and the first reference data. Judge whether the mounting state is appropriate or inappropriate. In this example, first, the first determination unit 1014 receives electrocardiogram data from the first acquisition unit 1011. First determination unit 1014 receives the first reference data from third acquisition unit 1013. Next, the first determination unit 1014 compares the electrocardiographic data with the first reference data. For example, the first determination unit 1014 compares the waveform data of the electrocardiographic data with the waveform data of the first reference data. It is preferable that the first determination unit 1014 uses reference data that is close to the measurement date and time of the electrocardiogram among a plurality of reference data included in the first reference data. When the first reference data includes a plurality of reference data measured in different states of the subject, the first determination unit 1014 may use the plurality of reference data. Next, the first determination unit 1014 determines whether the subject's wearing state of the electrocardiogram measurement unit 109 is appropriate or inappropriate based on the comparison result between the electrocardiogram data and the first reference data. For example, when the degree of deviation of the electrocardiographic data from the first reference data is less than the threshold, the first determination unit 1014 determines that the subject's wearing state of the electrocardiographic measurement unit 109 is appropriate. On the other hand, if the degree of deviation of the electrocardiographic data from the first reference data is equal to or greater than the threshold, the first determination unit 1014 determines that the subject's wearing state of the electrocardiographic measurement unit 109 is inappropriate. Next, the first determination unit 1014 determines whether the subject's wearing state of the blood pressure measuring unit 110 is appropriate or inappropriate according to whether the subject's wearing state of the electrocardiographic measuring unit 109 is appropriate or inappropriate. I do. The first determination unit 1014 determines that the mounting state of the blood pressure measurement unit 110 by the subject is appropriate according to the determination result indicating that the mounting state of the electrocardiographic measurement unit 109 by the subject is appropriate. On the other hand, the first determination unit 1014 determines that the mounting state of the blood pressure measurement unit 110 by the subject is inappropriate according to the determination result indicating that the mounting state of the electrocardiographic measurement unit 109 by the subject is inappropriate. Is determined. The first determination unit 1014 makes this determination for the following reason. The electrocardiogram measurement unit 109 and the blood pressure measurement unit 110 are composed of different elements, but are both included in the measurement device 1. Therefore, if the subject's wearing state of the electrocardiographic measurement unit 109 is appropriate, there is a high possibility that the subject's wearing state of the blood pressure measurement unit 110 is appropriate. On the other hand, if the subject's wearing state of the electrocardiographic measurement unit 109 is inappropriate, there is a high possibility that the subject's wearing state of the blood pressure measurement unit 110 is inappropriate.

Note that the first determination unit 1014 may perform the following when comparing the electrocardiographic data with any of a plurality of reference data included in the first reference data. For example, when the degree of divergence of the electrocardiographic data with respect to at least one reference data is less than the threshold, the first determining unit 1014 may determine that the subject's wearing state of the electrocardiographic measuring unit 109 is appropriate. . The first determination unit 1014 determines that the mounting state of the blood pressure measurement unit 110 by the subject is appropriate according to the determination result indicating that the mounting state of the electrocardiographic measurement unit 109 by the subject is appropriate. On the other hand, when the degree of divergence of the electrocardiographic data with respect to all the reference data of the arbitrary plurality of reference data is equal to or greater than the threshold, the first determination unit 1014 determines that the subject's wearing state of the electrocardiographic measurement unit 109 is not correct. It may be determined that it is appropriate. The first determination unit 1014 determines that the mounting state of the blood pressure measurement unit 110 by the subject is inappropriate according to the determination result indicating that the mounting state of the electrocardiographic measurement unit 109 by the subject is inappropriate. I do. Note that the comparison between the electrocardiographic data and the first reference data may be performed using various methods, and is not limited.

In another example, the first determination unit 1014 indirectly determines whether the subject is properly or inappropriately wearing the blood pressure measurement unit 110 based on the electrocardiogram data itself. In this example, first, the first determination unit 1014 receives electrocardiogram data from the first acquisition unit 1011. The first determination unit 1014 determines whether the subject's wearing state of the electrocardiogram measurement unit 109 is appropriate or inappropriate based on the degree of physical quantity fluctuation in the electrocardiogram data itself. Various determinations may be made by the subject based on the electrocardiogram data itself to determine whether the electrocardiogram measurement unit 109 is properly or inappropriately mounted, and is not limited. The first determination unit 1014 determines whether the subject's wearing state of the blood pressure measurement unit 110 is appropriate or inappropriate, depending on whether the subject's wearing state of the electrocardiographic measurement unit 109 is appropriate or inappropriate.

The first determination unit 1014 generates a first determination result. The first determination result indicates whether the mounting state of the blood pressure measurement unit 110 by the subject is appropriate or inappropriate. First determination unit 1014 outputs the first determination result to second determination unit 1015.

The second determination unit 1015 will be described. The second determination unit 1015 determines whether the reliability of the blood pressure data is high or low according to the first determination result, as exemplified below. First, the second determination unit 1015 receives the blood pressure data from the second acquisition unit 1012. The second determination unit 1015 receives the first determination result from the first determination unit 1014. Next, the second determination unit 1015 analyzes the content of the first determination result. The second determination unit 1015 determines that the reliability of the blood pressure data is high in response to the acquisition of the first determination result indicating that the subject's wearing state of the blood pressure measurement unit 110 is appropriate. One reason is that the accuracy of blood pressure measurement by the blood pressure measurement unit 110 is high if the subject's wearing state of the blood pressure measurement unit 110 is appropriate. On the other hand, the second determination unit 1015 determines that the reliability of the blood pressure data is low in response to the acquisition of the first determination result indicating that the mounting state of the blood pressure measurement unit 110 by the subject is inappropriate. One reason is that the accuracy of blood pressure measurement by the blood pressure measurement unit 110 is low if the subject's wearing state of the blood pressure measurement unit 110 is inappropriate.

The second determination unit 1015 generates a second determination result. The second determination result indicates whether the reliability of the blood pressure data is high or low. Second determination unit 1015 outputs the second determination result to data output unit 1016 and signal output unit 1017.

The data output unit 1016 will be described. The data output unit 1016 outputs blood pressure data associated with data indicating whether the reliability of the blood pressure data is high or low, as exemplified below. First, the data output unit 1016 receives the blood pressure data from the second acquisition unit 1012. Data output unit 1016 receives the second determination result from second determination unit 1015. The data output unit 1016 analyzes the contents of the second determination result. The data output unit 1016 generates data indicating whether the reliability of the blood pressure data is high or low in accordance with the second determination result. Data indicating whether the reliability of the blood pressure data is high or low is also referred to as reliability data. The data output unit 1016 associates the reliability data with the blood pressure data. For example, the data output unit 1016 associates the reliability data with the blood pressure data by adding (labeling) the reliability data to the blood pressure data. Next, the data output unit 1016 outputs the blood pressure data associated with the reliability data to the PHR server 3 via the communication interface 105. Thereby, the PHR server 3 can manage the blood pressure data in association with the reliability data.

The signal output unit 1017 will be described. The signal output unit 1017 outputs a support signal according to a second determination result indicating that the reliability of the blood pressure data is low, as exemplified below. The support signal is a signal that instructs execution of support for improving the wearing state of the blood pressure measurement unit 110 for the subject. First, the signal output unit 1017 receives the second determination result from the second determination unit 1015. Next, the signal output unit 1017 analyzes the content of the second determination result and determines whether the reliability of the blood pressure data is high or low. When the second determination result indicates that the reliability of the blood pressure data is low, the signal output unit 1017 outputs a support signal. On the other hand, when the second determination result indicates that the reliability of the blood pressure data is high, the signal output unit 1017 omits the output of the support signal.

For example, the signal output unit 1017 outputs a support signal to at least one of the display unit 107 and the audio output unit 108. The display unit 107 displays a screen of a message indicating that the wearing state of the blood pressure measurement unit 110 by the subject is not appropriate based on the support signal. The voice output unit 108 outputs a voice message indicating that the wearing state of the blood pressure measurement unit 110 by the subject is not appropriate based on the support signal. The message may be any content as long as the message indicates that the wearing state of the blood pressure measurement unit 110 by the subject is not appropriate, and is not limited. The subject can appropriately re-attach the blood pressure measurement unit 110 by the message. Thereby, the measuring device 1 can obtain highly reliable blood pressure data. Note that the signal output unit 1017 may output the support signal to elements other than the display unit 107 and the audio output unit 108. The signal output unit 1017 may output a support signal to a support providing device that provides an external stimulus to the subject. For example, the external stimulus is, but not limited to, a vibration.

§3 Operation example
<Measuring device>
[Reliability judgment operation]
FIG. 5 is a flowchart illustrating a reliability determination operation in the measurement device 1. The processing procedure described below is merely an example, and each processing may be changed as much as possible. In the processing procedure described below, steps can be omitted, replaced, and added as appropriate.

The first acquisition unit 1011 acquires the subject's electrocardiogram data (step S101). In step S101, the first acquisition unit 1011 acquires the subject's electrocardiogram data from the storage device 104 as illustrated. The first acquisition unit 1011 outputs electrocardiogram data to the second acquisition unit 1012 and the first determination unit 1014.

The second acquiring unit 1012 acquires the blood pressure data of the subject measured within a predetermined period including the measurement date and time of the electrocardiographic data of the subject (Step S102). In step S102, the second acquisition unit 1012 acquires the subject's blood pressure data from the storage device 104 with reference to the measurement date and time of the electrocardiographic data, as illustrated. The second acquisition unit 1012 outputs to the data output unit 1016.

The first determination unit 1014 determines whether the subject's wearing state of the blood pressure measurement unit 110 is appropriate or inappropriate (step S103). In step S103, the first determination unit 1014 indirectly determines whether the subject's wearing state of the blood pressure measurement unit 110 is appropriate or inappropriate based on the electrocardiographic data, as illustrated. First determination unit 1014 outputs the first determination result to second determination unit 1015.

The second determination unit 1015 determines whether the reliability of the blood pressure data is high or low (step S104). In step S104, the second determination unit 1015 determines whether the reliability of the blood pressure data is high or low according to the first determination result, as illustrated. Second determination unit 1015 outputs the second determination result to data output unit 1016 and signal output unit 1017.

The data output unit 1016 outputs the blood pressure data associated with the reliability data (Step S105). In step S105, the data output unit 1016 outputs the blood pressure data associated with the reliability data according to the second determination result to the external device via the communication interface 105 as illustrated.

The signal output unit 1017 determines whether the reliability of the blood pressure data is high or low (step S106). In step S106, as illustrated, the signal output unit 1017 determines whether the reliability of the blood pressure data is high or low based on the second determination result. If the reliability of the blood pressure data is high (No at Step S106), the processor 101 ends the reliability determination operation. When the reliability of the blood pressure data is low (Step S106, Yes), the signal output unit 1017 outputs a support signal (Step S107). In step S107, the signal output unit 1017 outputs a support signal to at least one of the display unit 107 and the audio output unit 108, as illustrated.

The processor 101 can repeatedly execute the above-described reliability determination operation every time the subject's electrocardiogram data is acquired from the storage device 104.

§4 Function / Effect As described above, in the present embodiment, the measuring device 1 determines whether the reliability of the second biometric data is high or low according to the first determination result based on the first biometric data. Can be determined.
For example, there is biometric data that not only fluctuates according to the mounting state of the measurement unit included in the measurement device 1 by the subject, but also sensitively reacts to an abnormal body. On the other hand, there is biometric data that not only varies according to the mounting state of the measuring unit included in the measuring device 1 by the subject but also does not react so much in the resting state if the abnormality that occurs on the body is mild. The former biometric data is susceptible to abnormalities in the subject's body. For this reason, the former biometric data is not suitable for evaluating whether the mounting state of the measurement unit for measuring the former biometric data included in the measuring device 1 by the subject is appropriate or inappropriate. The latter biometric data is not frequently affected by abnormalities in the subject's body. Therefore, the latter biometric data is suitable for evaluating whether the mounting state of the measurement unit for measuring the latter biometric data included in the measurement device 1 by the subject is appropriate or inappropriate. In addition, when the measurement device 1 includes two measurement units that measure different biological data, if the wearing state of one measurement unit by the subject is appropriate, the wearing state of the other measurement unit by the subject is also appropriate. Probability is high. On the other hand, if the mounting state of one measurement unit by the subject is inappropriate, it is highly likely that the mounting state of the other measurement unit by the subject is also inappropriate. The measurement device 1 uses the latter biometric data as first biometric data, and uses the former biometric data as second biometric data. Thereby, even if measurement device 1 cannot directly determine whether the measurement unit that measures the second biometric data by the subject is appropriate or inappropriate based on the second biometric data, Based on the first biometric data, it is possible to indirectly determine whether the mounting state of the measurement unit that measures the second biometric data by the subject is appropriate or inappropriate. As a result, even if it is difficult for the measurement device 1 to directly evaluate the reliability of the second biometric data based on the second biometric data, the measurement device 1 indirectly uses the second biometric data based on the first biometric data. The reliability of biometric data can be evaluated.

Further, in the present embodiment, the measurement device 1 can determine whether the subject's wearing state of the blood pressure measurement unit 110 is appropriate or inappropriate based on the comparison result between the first biological data and the reference data. .
The measurement apparatus 1 can accurately determine whether the subject's wearing state of the electrocardiographic measurement unit 109 is appropriate or inappropriate by using the reference data, so that the subject's wearing state of the blood pressure measurement unit 110 is appropriate. Whether it is inappropriate or not can be accurately determined.

Furthermore, in the present embodiment, the measurement device 1 can acquire the subject's electrocardiographic data as the first biometric data and acquire the subject's blood pressure data as the second biometric data.
Since the electrocardiographic data is not frequently affected by abnormalities of the subject's body, the electrocardiographic data is suitable for evaluating whether the subject's wearing state of the electrocardiographic measurement unit 109 is appropriate or inappropriate. Since the blood pressure data is easily affected by abnormalities in the body of the subject, the blood pressure data is not suitable for evaluating whether the wearing state of the blood pressure measurement unit 110 by the subject is appropriate or inappropriate. The measurement device 1 can measure the blood pressure by the subject based on the electrocardiographic data even if it is not possible to directly determine whether the wearing state of the blood pressure measurement unit 110 by the subject is appropriate or inappropriate based on the blood pressure data. It is possible to indirectly determine whether the mounting state of the unit 110 is appropriate or inappropriate. Even if it is difficult to directly evaluate the reliability of the blood pressure data based on the blood pressure data, the measuring device 1 can indirectly evaluate the reliability of the blood pressure data based on the electrocardiographic data.

Further, in the present embodiment, the measurement device 1 can output the support signal in accordance with the second determination result indicating that the reliability of the second biometric data is low.
The measurement device 1 can measure highly reliable second biological data by supporting the improvement of the state of attachment of the blood pressure measurement unit 110 to the subject.

Further, in the present embodiment, the measuring device 1 can output the second biological data associated with the reliability data.
The measurement device 1 can assist the doctor in diagnosing by providing the doctor with the second biometric data associated with the reliability data. By confirming the reliability of the second biometric data, the doctor can easily determine whether or not to use the second biometric data for the examination of the subject.
