[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] <Configuration of the Biometric Information Measurement System> FIG. 1 is a diagram showing an example of the overall configuration of a biological information measuring system 100 according to the present invention. 1, the biological information measuring system 100 includes a biological information measuring device 1 and a terminal device 2. The biological information measuring device 1 and the terminal device 2 are capable of transmitting and receiving data via wireless communication or wired communication.

[0011] As shown in Fig. 2, the biological information measuring device 1 is attached to the ear (predetermined measurement site) of a user (subject) US and continuously measures the deep body temperature (ear temperature) of the user US for a long period of time as well as the heart rate of the user US. The terminal device 2 is carried by the user US and records deep body temperature data D1 and heart rate data D2 acquired from the biological information measuring device 1 in a storage unit 23 (see Fig. 6) and displays them on a display unit 24 (see Fig. 6).

[0012] <Configuration of the biological information measuring device> FIG. 3 is a block diagram showing the functional configuration of the biological information measuring device 1. As shown in FIG. As shown in FIG. 3, the biological information measuring device 1 is configured to include a control unit 11, a body temperature measuring unit 12, a heart rate measuring unit 13, a storage unit 14, and a communication unit 15.

[0013] The control unit (adjustment means) 11 is a computer that controls each part of the biological information measuring device 1. Specifically, the control unit 11 is configured with at least one CPU (Central Processing Unit), RAM (Random Access Memory), etc., reads out a specified program from among programs stored in the storage unit 14, expands the program in the RAM, and executes various processes in cooperation with the expanded program.

[0014] The body temperature measuring unit 12 is composed of a chip-type temperature sensor IC (integrated circuit) that outputs a digital signal representing the detected temperature, a circuit that outputs the digital signal to the control unit 11, and the like. Note that the body temperature measuring unit 12 is not limited to this, and may be equipped with a temperature sensor IC that outputs an analog voltage signal whose magnitude corresponds to the detected temperature, or may be equipped with a temperature detection element (e.g., a thermistor, etc.) whose electrical characteristics change according to temperature.

[0015] The heartbeat measuring unit 13 is composed of a sensor that detects the heartbeat of the user US, a circuit that counts the detected heartbeats, calculates the number of heartbeats per unit time (e.g., 60 seconds), and outputs the result as a measurement result to the control unit 11. The heartbeat measuring unit 13 detects the heartbeat according to, for example, a photoplethysmography method.

[0016] The storage unit 14 is configured with a non-volatile semiconductor memory, etc. The storage unit 14 stores various programs and data required for executing the programs.

[0017] For example, the storage unit 14 stores an offset temperature table 141. FIG. 4 is a diagram showing an example of the offset temperature table 141. As shown in FIG. The offset temperature table 141 is a table showing the heat generation effect on the deep body temperature measured by the body temperature measuring unit 12 when a current flows through the light emitting element (LED (Light Emitting Diode)) constituting the heartbeat measuring unit 13, that is, when the heartbeat is measured by the heartbeat measuring unit 13. As shown in FIG. 4, the offset temperature table 141 stores the currents (LED current (current consumption)) of 5 mA, 10 mA, and 17 mA flowing through the light emitting element, in association with the temperature rise (°C) indicating how much the temperature measured by the body temperature measuring unit 12 rises for each measurement time (s) of the heartbeat by the heartbeat measuring unit 13. For example, when the current flowing through the light emitting element is set to 5 mA and the heartbeat is measured for 300 seconds by the heartbeat measuring unit 13, it can be seen from this offset temperature table 141 that the temperature measured by the body temperature measuring unit 12 rises by 0.23°C compared to the temperature when the heartbeat is not measured by the heartbeat measuring unit 13. 5, when the core body temperature is measured by the body temperature measuring unit 12, the current flowing through the light-emitting element is set to 5 mA, and the heart rate is measured for 300 seconds by the heart rate measuring unit 13, the temperature measurement error by the body temperature measuring unit 12 due to the heat generation effect can be suppressed by subtracting the temperature rise of "0.23°C (ΔT)" from the core body temperature measured by the body temperature measuring unit 12. If the measurement time of the heart rate by the heart rate measuring unit 13 exceeds 400 seconds, the temperature rise due to the measurement of the heart rate is assumed to be stable, and the temperature rise of "0.2315°C (ΔT)" corresponding to 400 seconds is subtracted (similarly when the set current is 10 mA or 17 mA).

[0018] Returning to FIG. 3, the communication unit 15 performs communication control for transmitting and receiving data to and from an external device such as the terminal device 2 through wireless communication or wired communication.

[0019] <Configuration of terminal device> The terminal device 2 is, for example, a smart watch, a smartphone, or the like. FIG. 6 is a block diagram showing the functional configuration of the terminal device 2. As shown in FIG. As shown in FIG. 6, the terminal device 2 includes a control unit 21, an operation unit 22, a storage unit 23, a display unit 24, and a communication unit 25.

[0020] The control unit 21 is a computer that controls each part of the terminal device 2. Specifically, the control unit 21 is configured with at least one CPU, a RAM (Random Access Memory), etc., reads out a specified program from among the programs stored in the storage unit 23, expands it in the RAM, and executes various processes in cooperation with the expanded program.

[0021] The operation unit 22 is composed of push button switches, a touch panel attached to the display unit 24, and the like. The operation unit 22 outputs an operation signal of the push button switch by the user US and an operation signal on the screen of the display unit 24 to the control unit 21.

[0022] The storage unit 23 is configured with a non-volatile semiconductor memory, a HDD (Hard Disk Drive), etc. The storage unit 23 stores various programs and data required for executing the programs. The storage unit 23 is not limited to being built into the terminal device 2, and may include an external recording medium that is detachable from the terminal device 2.

[0023] For example, the storage unit 23 stores a biological information management program 231. The biological information management program 231 is an application program for acquiring and recording the deep body temperature data D1 and the heartbeat data D2 from the biological information measuring device 1, and displaying them on the display unit 24. The storage unit 23 also stores the deep body temperature data D1 and the heartbeat data D2 acquired from the biological information measuring device 1.

[0024] The display unit 24 is configured with a display device such as a liquid crystal display, an organic EL (Electro Luminescence) display, or the like, and performs display based on the control operation of the control unit 21.

[0025] The communication unit 25 performs communication control for transmitting and receiving data to and from an external device such as the biological information measuring device 1 via wireless communication.

[0026] <<Operation of the Biometric Information Measurement System>> Next, the operation of the biological information measuring system 100 will be described. As an example, with reference to Fig. 7, the operation of the control unit 11 of the biological information measuring device 1 measuring the core body temperature (ear temperature) and heart rate, which are biological information of the user US, will be described. To achieve the above operation, the control unit 11 executes the biological information measuring process shown in Fig. 7. Also, with reference to Fig. 8, the operation of the control unit 11 generating the offset temperature table 141 will be described. To achieve the above operation, the control unit 11 executes the offset temperature table generating process shown in Fig. 8.

[0027] <Biometric information measurement processing> FIG. 7 is a flowchart showing a control procedure of the biological information measurement process. As shown in FIG. 7, when the vital information measurement process is started, the control unit 11 of the vital information measurement device 1 determines whether or not a measurement start instruction has been received from the terminal device 2 via the communication unit 15 (step S1).

[0028] In step S1, when it is determined that a measurement start instruction has not been received from the terminal device 2 via the communication unit 15 (step S1; NO), the control unit 11 ends the biological information measurement process.

[0029] Also, in step S1, if it is determined that a measurement start instruction has been received from the terminal device 2 via the communication unit 15 (step S1; YES), the control unit 11 causes the body temperature measuring unit 12 to start measuring the deep body temperature and the heart rate measuring unit 13 to start measuring the heart rate (step S2).

[0030] Next, the control unit 11 acquires deep body temperature data D1 measured by the body temperature measuring unit 12 and heart rate data D2 measured by the heart rate measuring unit 13 (step S3).

[0031] Next, the control unit 11 refers to the offset temperature table 141 (see Figure 4) and subtracts from the deep body temperature data D1 acquired in step S3 an offset temperature corresponding to the value of the current flowing through the light-emitting element of the heart rate measurement unit 13 at that time and the elapsed time since the start of heart rate measurement (step S4).

[0032] Next, the control unit 11 transmits the deep body temperature data D1 after the offset temperature has been subtracted in step S4, and the heartbeat data D2 acquired in step S3 to the terminal device 2 via the communication unit 15 (step S5). The deep body temperature data D1 and the heartbeat data D2 transmitted to the terminal device 2 are displayed on the display unit 24 of the terminal device 2 and stored in the storage unit 23.

[0033] Next, the control unit 11 determines whether or not a measurement end instruction has been received from the terminal device 2 via the communication unit 15 (step S6).

[0034] In step S6, if it is determined that the measurement end instruction has not been received from the terminal device 2 via the communication unit 15 (step S6; NO), the control unit 11 returns the process to step S3 and repeats the subsequent processes.

[0035] Furthermore, in step S6, if it is determined that a measurement end instruction has been received from the terminal device 2 via the communication unit 15 (step S6; YES), the control unit 11 ends the biological information measurement process.

[0036] <Offset temperature table generation process> FIG. 8 is a flowchart showing a control procedure for the offset temperature table generating process. As shown in FIG. 8, when the offset temperature table generating process is started, the control unit 11 of the vital information measuring device 1 starts the operation of the body temperature measuring unit 12 (step S11).

[0037] Next, the control unit 11 acquires initial data (template data) for the table to be generated (step S12).

[0038] Next, the control unit 11 determines whether or not the rising temperatures corresponding to all the set currents (5 mA, 10 mA, 17 mA) have been stored in the table (step S13).

[0039] In step S13, if it is determined that the rising temperatures corresponding to all the set currents (5 mA, 10 mA, 17 mA) are not stored in the above table (step S13; NO), the control unit 11 sets a current corresponding to the unstored rising temperature in the heart rate measurement unit 13 (step S14).

[0040] Next, the control unit 11 starts the operation of the heart rate measuring unit 13 (step S15).

[0041] Next, the control unit 11 measures the rising temperature in the body temperature measuring unit 12 at predetermined time intervals (e.g., 10 seconds, 50 seconds, . . . , 400 seconds) (step S16). Here, the rising temperature is the rising temperature based on the temperature measured when the operation of the body temperature measuring unit 12 is started in step S11.

[0042] Next, the control unit 11 stores the increased temperature measured in step S16 in the above table (step S17).

[0043] Next, the control unit 11 returns the process to step S13, and repeats the processes from step S14 onwards until the increased temperatures corresponding to all the set currents (5 mA, 10 mA, 17 mA) are stored in the above table.

[0044] Furthermore, in step S13, if it is determined that the rising temperatures corresponding to all the set currents (5 mA, 10 mA, 17 mA) have been stored in the table (step S13; YES), the control unit 11 ends the offset temperature table generation process. By ending this offset temperature table generation process, the offset temperature table 141 (see FIG. 4) is generated.

[0045] Effect As described above, the biological information measuring device 1 includes a body temperature measuring unit 12 that is attached to a user (subject) US and measures the deep body temperature of the user US, a heartbeat measuring unit 13 that is attached to the user US and measures the heartbeat of the user US, and a control unit 11 that adjusts the measurement value of the deep body temperature measured by the body temperature measuring unit 12 based on the heat generation effect that the measurement of the heartbeat by the heartbeat measuring unit 13 has on the measurement of the deep body temperature by the body temperature measuring unit 12. Therefore, according to the biological information measuring device 1, the measurement value of the deep body temperature measured by the body temperature measuring unit 12 is adjusted taking into account the heat generation effect that the measurement of the heartbeat by the heartbeat measuring unit 13 has on the measurement of the deep body temperature by the body temperature measuring unit 12, so that it is possible to prevent the measurement accuracy of the deep body temperature from decreasing due to the measurement of the heartbeat. In addition, according to the biological information measuring device 1, it is not necessary to take physical measures such as providing a heat insulating material between the body temperature measuring unit 12 and the heartbeat measuring unit 13, so that it is possible to prevent the device from becoming large in size.

[0046] Furthermore, the control unit 11 of the biological information measuring device 1 adjusts the measurement value of the deep body temperature measured by the body temperature measuring unit 12 by subtracting the offset temperature corresponding to the current value when the heartbeat was measured by the heartbeat measuring unit 13 from the measurement value of the deep body temperature measured by the body temperature measuring unit 12 based on an offset temperature table 141 in which the value of the current flowing through the light-emitting element of the heartbeat measuring unit 13 is associated with the offset temperature. Therefore, the biological information measuring device 1 can quickly and accurately adjust the measurement value of the deep body temperature.

[0047] <Other> The description of the above embodiment is merely an example of the biological information measuring device, the biological information measuring method, and the program according to the present invention, and the present invention is not limited to this. For example, in the above embodiment, the offset temperature table 141 is generated by executing an offset temperature table generation process (see FIG. 8) in the vital information measuring device 1, but an offset temperature table generated in advance in a representative sample vital information measuring device 1 may be provided to each vital information measuring device 1.

[0048] In the above embodiment, the deep body temperature measured by the body temperature measuring unit 12 is adjusted by subtracting the corresponding offset temperature (rising temperature) from the deep body temperature measured by the body temperature measuring unit 12 using the offset temperature table 141, but this adjustment method is merely an example, and other adjustment methods may be used. As another adjustment method, as shown in Fig. 9, the deep body temperature measured by the body temperature measuring unit 12 may be adjusted by subtracting a time constant related to the rising temperature that corresponds to the elapsed time since the heartbeat measurement was started in the heartbeat measuring unit 13, which is the subtraction data, from the deep body temperature data measured by the body temperature measuring unit 12, which is the measurement raw data. Note that the above time constants are prepared corresponding to currents of 5 mA, 10 mA, and 17 mA flowing through the light-emitting element of the heartbeat measuring unit 13, respectively.

[0049] In the above embodiment, the measured value of the deep body temperature measured by the body temperature measuring unit 12 is adjusted to reduce the heat generation effect of the heartbeat measurement by the heartbeat measuring unit 13 on the deep body temperature measurement by the body temperature measuring unit 12, but this method is merely an example, and other methods may be used. For example, during sleep, the amount of activity of the human body is low, and the fluctuation of the heartbeat and the change in the deep body temperature are small. For this reason, at least during sleep, as shown in FIG. 10, the interval (measurement interval) of the heartbeat measurement by the heartbeat measuring unit 13 may be increased and the measurement time for each measurement may be shortened, that is, the heartbeat measurement operation by the heartbeat measuring unit 13 may be performed intermittently, thereby reducing the heat generation effect of the heartbeat measurement by the heartbeat measuring unit 13 on the deep body temperature measurement by the body temperature measuring unit 12. In such a case, it is preferable to have in advance data regarding the above-mentioned measurement interval and measurement time that do not generate heat (in other words, the temperature rise at which there is no heat generation effect or the heat generation effect can be negligible). Note that. A correlation table between the effective value of the current (set current (LED current)) and the temperature rise when the heartbeat measurement unit 13 is caused to perform heartbeat measurement intermittently may be stored in the storage unit 14, and when the deep body temperature is measured by the body temperature measurement unit 12, the correlation table may be referenced to subtract the temperature rise corresponding to the effective value of the set current. In this case, the heat generation effect caused by the measurement of the heartbeat by the heartbeat measurement unit 13 on the measurement of the deep body temperature by the body temperature measurement unit 12 can be suppressed compared to the above embodiment.

[0050] Also, at least during sleep, as shown in FIG. 11, after the heartbeat measuring unit 13 measures the heartbeat for a predetermined time, if the heat generation effect of the heartbeat measuring unit 13 has subsided, a series of measurement operations may be repeated in which the body temperature measuring unit 12 measures the deep body temperature for a predetermined time, thereby reducing the heat generation effect of the heartbeat measurement by the heartbeat measuring unit 13 on the deep body temperature measurement by the body temperature measuring unit 12. In such a case, correlation data between the set current (LED current) and the time when the heartbeat measuring unit 13 measures the heartbeat, and the time from the end of the heartbeat measuring operation until the rising temperature falls below a threshold value, is stored in the storage unit 14, and whether the heat generation effect of the heartbeat measuring unit 13 has subsided or not is determined based on the correlation data. Note that the storage unit 14 may be provided with a correlation table between the effective value of the current (set current (LED current)) when the heartbeat measuring unit 13 measures the heartbeat and the rising temperature, and when the body temperature measuring unit 12 measures the deep body temperature, the correlation table may be referred to and the rising temperature corresponding to the effective value of the set current may be subtracted. In this embodiment, the operation of measuring the heart rate and the operation of measuring the core body temperature are repeatedly performed at predetermined intervals.

[0051] In the above embodiment, one offset temperature table 141 (see FIG. 4) is stored in the storage unit 14 of the vital information measuring device 1, but, for example, a unique offset temperature table corresponding to each of a plurality of environmental temperatures (outside air temperatures) may be stored. In this case, when the offset temperature table is referred to in step S4 of the vital information measuring process (see FIG. 7), the offset temperature table corresponding to the environmental temperature at that time is referred to.

[0052] In addition, in the above embodiment, a control procedure for generating one offset temperature table is shown in the offset temperature table generation process (see FIG. 8). However, for example, an offset temperature table corresponding to each environmental temperature (outside air temperature) may be generated.

[0053] In addition, in the above embodiment, the case where the bioinformation measuring device 1 is attached to the ear of the user US to measure deep body temperature and heart rate is described, but the bioinformation measuring device 1 may also be a device that measures deep body temperature and heart rate by being attached to another measurement site, such as the armpit.

[0054] In the above description, an example has been disclosed in which a non-volatile semiconductor memory or the like is used as the computer-readable medium for the program according to the present invention, but the present invention is not limited to this example. As other computer-readable media, information recording media such as CD-ROMs can be applied. In addition, a carrier wave can also be applied to the present invention as a medium for providing data of the program according to the present invention via a communication line.

[0055] Furthermore, the detailed configurations and operations of the components of the vital information measuring device 1 and the terminal device 2 in the above-described embodiment may of course be modified as appropriate without departing from the spirit of the present invention.
