[0001] The present invention relates to a biological information measuring system, a biological information measuring program, and a biological information measuring device. [Background technology]

[0002] As an apparatus for measuring multiple pieces of vital signs and processing the information to determine the state of the living body, a vital signs measuring device has been disclosed which measures, for example, blood pressure values ​​and cardiac action potential waveforms and determines the likelihood of a subject's physical condition changing from the measurement results (e.g., Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-176340 A Summary of the Invention [Problem to be solved by the invention]

[0004] For example, when processing the waveform of cardiac action potential, a filter process for removing noise contained in the waveform, a judgment process for judging whether the cardiac function is normal or not using a predetermined algorithm, etc. are considered. However, a relatively large calculation cost is required to execute such a process. Therefore, in order to improve the calculation function, it is necessary to provide the biological information measuring device with a high-performance processor. As a result, it is expected that the size of the biological information measuring device will increase and the power consumption will increase. Therefore, it is expected that it will become difficult to carry the biological information measuring device, and the convenience will decrease.

[0005] The present invention has been made in consideration of the above-mentioned situation, and its purpose is to provide a technology that suppresses a decrease in the convenience of a biological information measuring device and enables analysis of multiple pieces of biological information. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the present invention employs the following configuration.

[0008] Here, the first processing related to the display includes a calculation process based on the first information measured by the measurement unit, and the second processing related to the display includes a filter process for the second information measured by the measurement unit.

[0009] The first process related to diagnosis includes a determination process capable of diagnosing the health condition of the subject based on the first information measured by the measurement unit, and the second process related to diagnosis includes a determination process capable of diagnosing the health condition of the subject based on the second information measured by the measurement unit.

[0010] According to this configuration, it is possible to measure and analyze a plurality of pieces of biological information. Also, according to this configuration, the calculation cost of the biological information measuring device is reduced compared to when the second process is executed in the biological information measuring device. Therefore, it is possible to suppress an increase in the size of the processor mounted in the biological information measuring device and an increase in power consumption. Therefore, it becomes easy to carry the biological information measuring device, and convenience is improved.

[0011] In the biological information measuring system according to the aforementioned aspect, the terminal may further include a second display unit capable of displaying the second information obtained by executing the second processing in the second processing unit.

[0012] According to this configuration, the measurement subject can check the second information from the terminal even if he or she does not carry a vital information measurement device.

[0016] Here, the second process includes a filtering process for removing noise from the waveform of the cardiac action potential, or a determination process for determining whether the cardiac function is normal or not.

[0017] According to this configuration, it is possible to measure and analyze blood pressure and cardiac action potential. Furthermore, according to this configuration, the calculation cost of the biological information measurement device is reduced compared to when the second process is executed in the biological information measurement device. Therefore, it is possible to reduce the calculation cost of the biological information measurement device.

[0019] According to this configuration, it is possible to measure and analyze blood pressure and cardiac action potential. Also, according to this configuration, the calculation cost of the biological information measurement device is reduced compared to when the second process is executed in the biological information measurement device. Therefore, the size of the processor mounted on the biological information measurement device can be reduced. Therefore, the size of the biological information measurement device is prevented from increasing.

[0020] In the bioinformation measuring device relating to the above-mentioned aspect, the second information may include at least one of information of blood pressure, pulse wave, transcutaneous arterial oxygen saturation, action potential generated from muscle fibers, acceleration in a predetermined direction of the bioinformation measuring device, transmission or reflection intensity of light irradiated from the bioinformation measuring device, air temperature surrounding the bioinformation measuring device, and body temperature of the subject to which the bioinformation measuring device is worn.

[0021] According to this configuration, it is possible to measure and analyze the biological information and the second information that affects the biological information. Also, according to this configuration, the calculation cost of the biological information measuring device is reduced compared to when the second process is executed in the biological information measuring device. Therefore, the size of the processor mounted on the biological information measuring device can be reduced. Therefore, the size of the biological information measuring device that measures information related to multiple biological information is suppressed.

[0022] In the bioinformation measuring device relating to the above-mentioned aspect, the display unit may synchronize the timing of displaying the first information for which the first processing has been performed in the first processing unit and the second information for which the second processing has been performed in the second processing unit.

[0023] According to this configuration, two different pieces of information, the first information and the second information, can be checked simultaneously, thereby improving convenience. Effect of the Invention

[0051] (Operation flow of each device) Next, an overview of the operation flows of the biological information measuring device 10 and the smartphone 50 will be described.

[0052] (Blood pressure measurement flow in biological information measurement device 10) FIG. 4 illustrates an outline of a blood pressure measurement flow in the biological information measurement device 10.

[0053] (S101) In step S101, the operation accepting unit 106 accepts an operation input on the touch panel display 23. Then, the operation accepting unit 106 notifies the blood pressure measurement control unit 103 that the operation has been input.

[0054] (S102) In step S102, blood pressure measurement is started. More specifically, upon being notified of the operation input in step S101, the blood pressure measurement control unit 103 generates a control signal for controlling the valve opening of the exhaust valve 19. Then, the blood pressure measurement control unit 103 generates drive signals for the compression cuff 12 and the sensing cuff 15. Then, the blood pressure measurement control unit 103 transmits the generated control signal and drive signal to the exhaust valve 19 and the pump 16.

[0055] (S103) In step S103, when pump 16 receives the drive signal generated in step S102, pump 16 drives in accordance with the drive signal. Also, when exhaust valve 19 receives the control signal generated in step S102, the opening degree of exhaust valve 19 is controlled to a predetermined opening degree in accordance with the control signal. Also, blood pressure measurement control unit 103 acquires the internal pressure of sensing cuff 15 via pressure sensor 18.

[0056] (S104) In step S104, blood pressure measurement control unit 103 instructs memory unit 104 to store in the storage device the internal pressure of sensing cuff 15 sequentially acquired in step S103 via pressure sensor 18. In response to the instruction, memory unit 104 stores the internal pressure of sensing cuff 15 in the storage device.

[0057] (S105) In step S105, blood pressure measurement control unit 103 instructs display control unit 107 to display the internal pressure of sensing cuff 15 sequentially acquired via pressure sensor 18 in step S103 on touch panel display 23. Display control unit 107 receives internal pressure information of sensing cuff 15 from blood pressure measurement control unit 103 and instructs display unit 108 to display the internal pressure information in a predetermined area of ​​touch panel display 23. Then, display unit 108 displays the internal pressure information of sensing cuff 15 on touch panel display 23 in response to the instruction from display control unit 107.

[0058] (S106) In step S106, the blood pressure measurement control unit 103 calculates the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate for a predetermined period of time using the internal pressure of the sensing cuff 15 sequentially acquired via the pressure sensor 18 in step S103. A publicly known algorithm or an algorithm developed independently is used to calculate the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate for a predetermined period of time from the internal pressure of the sensing cuff 15. The blood pressure measurement control unit 103 also instructs the memory unit 104 to store the calculated systolic blood pressure value, diastolic blood pressure value, and pulse rate in the memory device. In response to the instruction, the memory unit 104 stores the systolic blood pressure value, diastolic blood pressure value, and pulse rate in the memory device.

[0059] (S107) In step S107, when the blood pressure measurement control unit 103 calculates the systolic blood pressure value and the diastolic blood pressure value, the blood pressure measurement control unit 103 determines that the blood pressure measurement is completed. The control unit 103 instructs the display control unit 107 to display on the touch panel display 23 the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate stored in the storage device.

[0060] (S108) In step S108, the display control unit 107, which has received the command from the blood pressure measurement control unit 103 in step S107, reads out the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate from the storage device and commands the display unit 108 to display them in a predetermined area of ​​the touch panel display 23. The display control unit 107 also controls the timing of displaying the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate in a predetermined area of ​​the touch panel display 23. The display control unit 107 also commands the display unit 108 to end the display of the internal pressure of the sensing cuff 15 that has been displayed on the touch panel display 23. In response to the command from the display control unit 107, the display unit 108 displays the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate in a predetermined area of ​​the touch panel display 23 instead of displaying the internal pressure of the sensing cuff 15.

[0061] (Flow of measuring cardiac action potential in biological information measuring device 10) FIG. 5 illustrates an outline of a measurement flow of a cardiac action potential in the biological information measurement device 10. As shown in FIG.

[0062] (S201) In step S201, the electrocardiogram control unit 101 is notified by the operation receiving unit 106 that an operation has been input to the touch panel display 23. Then, the electrocardiogram control unit 101 starts measuring the action potential of the heart. That is, the electrocardiogram control unit 101 controls components such as a switch provided in the electrocardiogram measurement circuit 22 so that the potential difference between the electrodes 20A and 21, with the potential of the electrode 20B as the reference potential, can be measured.

[0063] (S202) In step S202, the ECG signal quality judgment unit 102 acquires potential difference information between the electrodes 20A and 21, with the potential of the electrode 20B set as a reference potential, from the ECG measurement circuit 22. Then, the ECG signal quality judgment unit 102 judges whether the cardiac action potential information is analyzable or not. Then, if the ECG signal quality judgment unit 102 judges that the cardiac action potential information is analyzable, it inputs the information to the communication unit 105. If the ECG signal quality judgment unit 102 judges that the cardiac action potential information is not analyzable, it again acquires potential difference information between the electrodes 20A and 21, with the potential of the electrode 20B set as a reference potential, from the ECG measurement circuit 22.

[0064] (S203) In step S203, the communication unit 105 receives the cardiac action potential information input in step S202 and transmits a connection request signal to the external device. Then, the communication unit 105 determines whether or not an acceptance signal of the connection request has been received from the external device.

[0065] (S204) In step S204, if it is determined that the communication unit 105 has received an acceptance signal of the connection request from the external device, the communication unit 105 transmits cardiac action potential information to the external device.

[0066] On the other hand, if the communication unit 105 does not receive an acceptance signal for the connection request from the external device for a predetermined period of time, it instructs the storage unit 104 to temporarily store the cardiac action potential information in the storage device. Then, when the communication unit 105 receives an acceptance signal for the connection request from the external device, it transmits the cardiac action potential information temporarily stored in the storage device to the external device.

[0067] The storage unit 104 may temporarily store in the main storage device 26 the potential difference information acquired by the electrocardiogram signal quality determination unit 102 in step S202 for a predetermined period. In step S204, the potential difference information for the predetermined period may be transmitted collectively to an external device. Alternatively, the processes from step S202 to step S204 may be performed in a streaming manner.

[0068] (S205) In step S205, the electrocardiogram control unit 101 commands the storage unit 104 to store the cardiac action potential information in the storage device. Upon receiving the command from the electrocardiogram control unit 101, the storage unit 104 stores the cardiac action potential information in the storage device.

[0069] (S206) In step S206, the electrocardiogram control unit 101 instructs the display control unit 107 to display the measurement status of the cardiac action potential on the touch panel display 23. Upon receiving the instruction from the electrocardiogram control unit 101, the display control unit 107 instructs the display unit 108 to display the measurement status of the cardiac action potential in a predetermined area of ​​the touch panel display 23.

[0070] The display unit 108, in accordance with an instruction from the display control unit 107, causes the touch panel display 23 to display the measurement status of the cardiac action potential.

[0071] (S207) In step S207, when a predetermined period has elapsed since the start of measurement of the cardiac action potential in step S201, the electrocardiogram control unit 101 ends the measurement of the cardiac action potential. That is, the electrocardiogram control unit 101 controls components such as a switch provided in the electrocardiogram measurement circuit 22 so as not to measure the potential difference between the electrode 20A, which uses the potential of the electrode 20B as a reference potential, and the electrode 21.

[0072] (S208) In step S208, the communication unit 105 notifies the external device that the measurement of the cardiac action potential information has ended. Note that the external device refers to the device to which the cardiac action potential information was transmitted in step S203.

[0073] (S209) In step S209, the communication unit 105 determines whether or not the determination result of the cardiac function index has been received from the external device. If the communication unit 105 determines that the determination result of the cardiac function index has been received from the external device, the process proceeds to step S210.

[0074] (S210) In step S210, the storage unit 104 stores the cardiac function index determination result received in step S209 in the storage device.

[0075] (S211) In step S211, the display control unit 107 commands the display unit 108 to display the cardiac function index determination result received in step S209 in a predetermined area of ​​the touch panel display 23. The display unit 108 displays the cardiac function index determination result in a predetermined area of ​​the touch panel display 23 in response to the command from the display control unit 107.

[0076] (Display flow of cardiac action potential on smartphone 50) FIG. 6 shows an example of an outline of a display flow of cardiac action potentials on the smartphone 50.

[0077] (S501) In step S501, the communication unit 501 receives cardiac action potential information transmitted from an external device. In addition, such cardiac action potential information is continuously received. The collected cardiac action potential information, when graphed, may form a waveform.

[0078] (S502) In step S502, the filter unit 502 executes a filtering process to remove noise components from the waveform of the cardiac action potential received in step S501. The storage unit 505 stores the filtered cardiac action potential information in a storage device.

[0079] (S503) In step S503, the display unit 504 displays on the touch panel display 51 the waveform of the cardiac action potential from which noise has been removed in step S502.

[0080] (S504) In step S504, the communication unit 501 receives a notification that the measurement of cardiac action potential information has ended from the external device.

[0081] (S505) In step S505, the determination unit 503 determines the cardiac function index. That is, the determination unit 503 acquires a frequency spectrum from the waveform of the cardiac action potential information after the filter process stored in the storage device in step S502 by analysis using a predetermined algorithm. Then, based on the frequency spectrum, it is determined whether the cardiac function index is abnormal or not.

[0082] (S506) In step S506, the display unit 504 displays the cardiac function index determination result in step S505 in a predetermined area of ​​the touch panel display 51.

[0083] (S507) In step S507, the communication unit 501 transmits the cardiac function index determination result in step S505 to an external device.

[0084] (Example of operation of vital information measuring system 1) FIG. 7 illustrates an example of a biological information measurement flow executed by the entire biological information measurement system 1.

[0085] (S1001) In step S1001, the subject wraps the belt 11 around one arm to secure the biological information measuring device 10. Then, the subject taps the touch panel display 23 with a finger. Then, the operation receiving unit 106 receives this operation input. Then, the operation receiving unit 106 notifies the blood pressure measurement control unit 103 and the electrocardiogram control unit 101 that the operation input has been received.

[0086] (S1002) In step S1002, blood pressure measurement is started. More specifically, the blood pressure measurement control unit 103, which has been notified of the operation input in step S1001, generates a control signal to close the valve of the exhaust valve 19. Then, the blood pressure measurement control unit 103 controls the supply of a predetermined amount of air to the compression cuff 12 and the sensing cuff 15 for a predetermined period of time. Upload The blood pressure measurement control unit 103 generates a drive signal for pump 16. In addition, the blood pressure measurement control unit 103 generates a drive signal for stopping the drive of pump 16 after a predetermined period has elapsed. In addition, the blood pressure measurement control unit 103 generates a control signal for gradually increasing the opening of exhaust valve 19 after a predetermined period has elapsed. Then, the blood pressure measurement control unit 103 transmits the generated control signal and drive signal to exhaust valve 19 and pump 16.

[0087] (S1003) In step S1003, when the pump 16 receives the drive signal generated in step S1002, a predetermined amount of air is sent from the pump 16 to the compression cuff 12 and the sensing cuff 15. When the exhaust valve 19 receives the control signal generated in step S1002, the valve opening of the exhaust valve 19 is closed. Therefore, the compression cuff 12 and the sensing cuff 15 continue to inflate. Therefore, the sensing cuff 15 is pressed against the arm of the subject. Furthermore, the degree to which the sensing cuff 15 presses against the arm of the subject continues to increase. While the sensing cuff 15 continues to press against the arm of the subject, the blood pressure measurement control unit 103 acquires the internal pressure of the sensing cuff 15 via the pressure sensor 18. Furthermore, after a predetermined period of time has elapsed, the driving of the pump 16 is stopped, and the valve opening of the exhaust valve 19 is gradually opened. During this time, the blood pressure measurement control unit 103 continues to acquire the internal pressure of the sensing cuff 15 via the pressure sensor 18. Note that step S1003 is an example of the "measurement step" of the present disclosure.

[0088] (S1004) In step S1004, the blood pressure measurement control unit 103 instructs the memory unit 104 to store in the storage device the internal pressure of the sensing cuff 15 sequentially acquired in step S1003 via the pressure sensor 18. In response to the instruction, the memory unit 104 stores the internal pressure of the sensing cuff 15 in the storage device.

[0089] (S1005) In step S1005, the blood pressure measurement control unit 103 instructs the display control unit 107 to display the internal pressure of the sensing cuff 15 sequentially acquired via the pressure sensor 18 in step S1003 on the touch panel display 23. The display control unit 107 receives the internal pressure information of the sensing cuff 15 from the blood pressure measurement control unit 103 and instructs the display unit 108 to display the internal pressure information in a predetermined area (e.g., the upper half) of the touch panel display 23. Then, in response to the instruction from the display control unit 107, the display unit 108 displays the internal pressure information of the sensing cuff 15 on the touch panel display 23. FIG. 8 illustrates an overview of the touch panel display 23 in which the internal pressure information of the sensing cuff 15 is displayed in the upper half of the screen.

[0090] (S1006) In step S1006, the blood pressure measurement control unit 103 calculates the systolic blood pressure value and the diastolic blood pressure value using the internal pressure of the sensing cuff 15 sequentially acquired via the pressure sensor 18 in step S1003 (an example of the "first processing step" of the present disclosure). That is, for example, when a predetermined vibration is detected in the internal pressure of the sensing cuff 15 in the process of gradually opening the valve of the exhaust valve 19, the internal pressure of the sensing cuff 15 at that time is determined to be the systolic blood pressure value. Also, when the predetermined vibration is no longer detected in the internal pressure of the sensing cuff 15 after the systolic blood pressure value is detected, the internal pressure of the sensing cuff 15 at that time is determined to be the diastolic blood pressure value. Also, the blood pressure measurement control unit 103 calculates the pulse rate for one minute using the frequency of the internal pressure of the sensing cuff 15 from the detection of the systolic blood pressure value to the detection of the diastolic blood pressure value. Then, the blood pressure measurement control unit 103 instructs the storage unit 104 to store the calculated systolic blood pressure value, diastolic blood pressure value, and pulse rate in the storage device. Upon receiving the command, the memory unit 104 stores the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate in the storage device.

[0091] (S1007) In step S1007, when the blood pressure measurement control unit 103 has calculated the systolic blood pressure value and the diastolic blood pressure value, the blood pressure measurement control unit 103 determines that the blood pressure measurement is completed. Then, the blood pressure measurement control unit 103 commands the display control unit 107 to display the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate stored in the storage device on the touch panel display 23.

[0092] (S1008) In step S1008, the display control unit 107, which has received the command from the blood pressure measurement control unit 103 in step S1007, commands the display unit 108 to read the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate from the storage device and display them in the upper half of the area of ​​the touch panel display 23. Figure 9 is an example of a schematic diagram of the touch panel display 23 on which the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate are thus displayed.

[0093] The display control unit 107 also commands the display unit 108 to start displaying the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate shown in Fig. 9. The display control unit 107 also commands the display unit 108 to simultaneously start displaying the determination result of the cardiac function index in step S1026, which will be described later. In response to the command from the display control unit 107, the display unit 108 displays the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate in the upper half area of ​​the touch panel display 23 as shown in Fig. 9, and displays the determination result of the cardiac function index (described later) in the lower half area. Step S1008 is an example of a "display step" in the present disclosure.

[0094] (S1009) In step S1009, the electrocardiogram control unit 101, which has been notified by the operation receiving unit 106 in step S1001 that an operation input has been made to the touch panel display 23, starts measuring the action potential of the heart. That is, the electrocardiogram control unit 101 controls components such as a switch provided in the electrocardiogram measurement circuit 22 so as to be able to measure the potential difference between the electrodes 20A and 21 with the potential of the electrode 20B taken as a reference potential. In addition, the subject touches the electrodes 20A and 20B with the fingers of the arm opposite to the arm on which the biological information measurement device 10 is worn.

[0095] (S1010) In step S1010, the ECG signal quality judgment unit 102 acquires the potential difference between the electrodes 20A and 21 from the ECG measurement circuit 22, with the potential of the electrode 20B taken as a reference potential. Then, the ECG signal quality judgment unit 102 judges that cardiac action potential information can be analyzed from the potential difference. Then, the ECG signal quality judgment unit 102 determines that the potential difference is the cardiac action potential. Then, the ECG signal quality judgment unit 102 inputs to the communication unit 105 that it has been determined that cardiac action potential information can be analyzed. Note that step S1010 is an example of a "measurement step" in the present disclosure.

[0096] (S1011) In step S1011, the communication unit 105 receives the cardiac action potential information input in step S1010 and transmits a connection request to the communication unit 501 of the smartphone 50. Then, the communication unit 105 receives an acceptance signal of the connection request from the communication unit 501 of the smartphone 50.

[0097] (S1012) In step S1012, the communication unit 105 that has received a connection request signal from the communication unit 501 in step S1011 transmits cardiac action potential information to the communication unit 501. Note that such cardiac action potential information is continuously acquired via the electrocardiogram measuring circuit 22 and transmitted to the communication unit 501. Note that step S1011 is an example of a "first transmission step" of the present disclosure.

[0098] (S1013) In step S1013, the electrocardiogram control unit 101 commands the storage unit 104 to store the cardiac action potential information in the storage device. Upon receiving the command from the electrocardiogram control unit 101, the storage unit 104 stores the cardiac action potential information in the storage device.

[0099] (S1014) In step S1014, the electrocardiogram control unit 101 instructs the display control unit 107 to display the measurement status of the cardiac action potential on the touch panel display 23. Upon receiving the instruction from the electrocardiogram control unit 101, the display control unit 107 instructs the display unit 108 to display the measurement status of the cardiac action potential in the lower half of the touch panel display 23 as shown in FIG.

[0100] More specifically, the display control unit 107 displays the message “OK” on the lower half of the touch panel display 23. The display control unit 107 instructs the display unit 108 to display the characters "OK" and "NG." The display control unit 107 also instructs the display unit 108 to display waveforms corresponding to "OK" and "NG." Ta, If the measurement status of the cardiac action potential is normal, the display control unit 107 commands the display unit 108 to blink the "OK" portion. On the other hand, if the measurement status of the cardiac action potential is abnormal, the display control unit 107 commands the display unit 108 to blink the "NG" portion.

[0101] The display unit 108 displays the above information on the touch panel display 23 in accordance with a command from the display control unit 107. Fig. 8 illustrates a case where the measurement status of the cardiac action potential is normal. As shown in Fig. 8, the internal pressure of the sensing cuff 15 is displayed on the upper half of the touch panel display 23 by executing the process in step S1005.

[0102] (S1015) In step S1015, when a predetermined period has elapsed since the start of measurement of the cardiac action potential in step S1009, the electrocardiogram control unit 101 ends the measurement of the cardiac action potential. That is, the electrocardiogram control unit 101 controls components such as a switch provided in the electrocardiogram measurement circuit 22 so as not to measure the potential difference between the electrodes 20A and 21 with the potential of the electrode 20B as a reference potential.

[0103] (S1016) In step S1016, the communication unit 105 transmits to the communication unit 501 of the smartphone 50 a notification that the measurement of the cardiac action potential information has ended.

[0104] (S1017) In step S1017, the communication unit 501 of the smartphone 50 receives the cardiac action potential information transmitted from the communication unit 105 of the biological information measuring device 10 in step S1012. In addition, such cardiac action potential information is continuously received. Therefore, the received cardiac action potential information may form a waveform when graphed. Note that step S1017 is an example of a "first receiving step" of the present disclosure.

[0105] (S1018) In step S1018, the filter unit 502 performs a filter process to remove noise components from the waveform of the cardiac action potential received in step S1017. The storage unit 505 stores the cardiac action potential information after the filter process in the storage device. Step S1018 is an example of the "second processing step" of the present disclosure.

[0106] (S1019) In step S1019, the display unit 504 displays on the touch panel display 51 the waveform of the cardiac action potential from which noise has been removed in step S1018.

[0107] (S1020) In step S1020, the communication unit 501 receives the biological information measurement The communication unit 105 of the device 10 receives a message indicating that the measurement of cardiac action potential information has ended.

[0108] (S1021) In step S1021, the determination unit 503 determines the cardiac function index. That is, the determination unit 503 acquires, for example, heart rate information from the waveform of the cardiac action potential information after the filter processing stored in the storage device in step S1018. Then, the determination unit 503 determines whether the heart rate information is higher than a predetermined value. In addition, the determination unit 503 determines whether there is an abnormality in the cardiac rhythm by performing, for example, FFT analysis on the waveform of the cardiac action potential information. Note that step S1021 is an example of a "second processing step" of the present disclosure.

[0109] (S1022) In step S1022, the display unit 504 displays the cardiac function index determination result in step S1021 on the touch panel display 51. Fig. 10 illustrates an example of an outline of the cardiac function index determination result displayed on the touch panel display 51. Here, as shown in Fig. 10, the display unit 504 displays the cardiac function index in an area different from the area where the waveform of the cardiac action potential is displayed. Nozashi In the example shown in FIG. 10, the cardiac function is displayed. Nozashi An example is shown in which the result of the test is normal.

[0110] (S1023) In step S1023, the communication unit 501 transmits the determination result of the cardiac function index in step S1021 to the communication unit 105 of the biological information measuring device 10. Note that step S1023 is an example of a "second transmission step" in the present disclosure.

[0111] (S1024) In step S1024, the communication unit 105 of the biological information measuring device 10 receives the determination result of the cardiac function index transmitted in step S1023 from the communication unit 501 of the smartphone 50. Note that step S1024 is an example of a "second receiving step" in the present disclosure.

[0112] (S1025) In step S1025, the storage unit 104 stores the cardiac function index determination result received in step S1024 in the storage device.

[0113] (S1026) In step S1026, the display control unit 107 commands the display unit 108 to display the cardiac function index determination result received in step S1024 in the lower half of the touch panel display 23. As described above, the display of the cardiac function index determination result is value The display control unit 107 instructs the display unit 108 to simultaneously start displaying the diastolic blood pressure value, the diastolic blood pressure value, and the pulse rate (step S1008).

[0114] More specifically, as shown in FIG. 9, the display control unit 107 instructs the display unit 108 to display the characters "Normal" and "Abnormal" in the lower half of the touch panel display 23.

[0115] Furthermore, if the cardiac function index determination result is, for example, normal, the display control unit 107 commands the display unit 108 to blink the "Normal" portion. Alternatively, if the cardiac function index determination result is, for example, abnormal, the display control unit 107 commands the display unit 108 to blink the "Abnormal" portion. The display unit 108 displays the above information on the touch panel display 23 in accordance with the command from the display control unit 107. FIG. 9 illustrates an example in which the cardiac function index determination result is normal. Note that step S1026 is also referred to as the "display step" of the present disclosure. This is an example of a "p".

[0116] [Actions and Effects] According to the above-described biological information measuring system 1, the computation cost of the biological information measuring device 10 is reduced compared to when the filter processing for the waveform of the cardiac action potential is executed in the biological information measuring device 10. Therefore, the MCU 24 having a lower computation performance than the processor of the smartphone 50 can be adopted as the processor mounted in the biological information measuring device 10. Therefore, the increase in size of the processor of the biological information measuring device 10 and the increase in power consumption can be suppressed. Therefore, the biological information measuring device 10, which is mounted with components capable of measuring two biological information, namely blood pressure and cardiac action potential, as shown in FIG. 1 and FIG. 2, is suppressed from becoming larger. Therefore, the biological information measuring device 10 becomes easier to carry, and the convenience is improved.

[0117] Moreover, according to the above-described biological information measuring system 1, the filtering process for the waveform of the cardiac action potential and the process for determining the cardiac function index, which require a relatively high computational cost, are executed in the smartphone 50. Therefore, the processing speed of the entire system is improved compared to the case where these processes are executed in the biological information measuring device 10. Therefore, the biological information measuring device 10 can simultaneously display the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate (step S1008) and the determination result of the cardiac function index (step S1026) in real time (see FIG. 9). Therefore, the subject can check two different pieces of information, the blood pressure value and the cardiac function index, at the same time. Therefore, the convenience of the biological information measuring device 10 is improved.

[0118] Furthermore, according to the above-described bio-information measuring system 1, even if the person being measured does not carry the bio-information measuring device 10, he or she can check the waveform of the cardiac action potential and cardiac function indexes displayed on the touch panel display 51 of the smartphone 50.

[0119] Moreover, according to the above-described biological information measuring system 1, before transmitting cardiac action potential information from the biological information measuring device 10 to the smartphone 50 (step S1012), it is determined whether or not the cardiac action potential information can be analyzed by a simple determination that can be processed even by the inexpensive and low-function MCU 24 in the biological information measuring device 10 (step S1010). Therefore, according to the above-described biological information measuring system 1, the smartphone 50 is prevented from performing processes other than the filtering process (step S1018) and the cardiac function index determination process (step S1021). Therefore, it is possible to concentrate the computational resources of the smartphone 50 on the filtering process (step S1018) and the cardiac function index determination process (step S1021). Therefore, a decrease in processing speed is prevented.

[0120] Furthermore, according to the above-described biological information measuring system 1, the internal pressure of the sensing cuff 15 is displayed on the touch panel display 23 of the biological information measuring device 10 in step S1005 as shown in Fig. 8. Also, the measurement status of the cardiac action potential is displayed in step S1014 as shown in Fig. 8. Thus, the subject can recognize whether the blood pressure measurement or the cardiac action potential measurement is being performed normally during the measurement. Thus, the subject can redo the measurement before the blood pressure measurement result or the cardiac function index judgment result is displayed on the touch panel display 23 (steps S1008 and S1026).

[0121] §2 Variations According to the above-described biological information measuring system 1, information relating to the cardiac action potential is transmitted from the biological information measuring device 10 to the smartphone 50, and filtering and cardiac function index determination processing are performed in the smartphone 50. However, filtering and cardiac function index determination processing may be performed on the cardiac action potential information in the biological information measuring device 10. Blood pressure information is transmitted from the biological information measuring device 10 to the smartphone 50, and a filter process and a cardiac function index determination processing are performed on the blood pressure information in the biological information measuring device 10. A predetermined process may be executed.

[0122] In addition to the above-mentioned blood pressure and cardiac action potential information, the biological information measuring device 10 may measure a pulse wave, a percutaneous arterial blood oxygen saturation, an action potential generated from muscle fibers, an acceleration in a predetermined direction of the biological information measuring device 10, a transmission or reflection intensity of light irradiated from the biological information measuring device 10 toward the subject, an ambient temperature of the biological information measuring device 10, or a body temperature of the subject wearing the biological information measuring device 10, in addition to or instead of the blood pressure and cardiac action potential. The biological information measuring device 10 may measure at least two or more pieces of information about the living body. The smartphone 50 may execute a predetermined process on a predetermined piece of information among the pieces of information. The measurement information to be transmitted from the biological information measuring device 10 to the smartphone 50 and to be executed with a predetermined process may be a plurality of pieces of measurement information. Even in such a biological information measuring system, the same effect as that of the embodiment can be achieved.

[0123] In addition, in the above embodiment, the filtering process and the cardiac function index determination process are exemplified as the processes executed on the cardiac action potential information in the smartphone 50, but the processes in the smartphone 50 are not limited to such examples.

[0124] In addition, in the above embodiment, the systolic blood pressure value, diastolic blood pressure value, pulse rate, and the cardiac function index judgment results are displayed simultaneously on the touch panel display 23 as shown in steps S1008 and S1026, but these measurement results do not need to be displayed simultaneously.

[0125] Furthermore, the touch panel display 51 of the smartphone 50 does not need to display the waveform of the cardiac action potential or the assessment results of the cardiac function index.

[0126] In addition, in the biological information measurement device 10, the blood pressure measurement flow (steps S1002 to S1007) and a part of the measurement flow of the cardiac action potential (steps S1009 to S1016) may be processed sequentially or in parallel.

[0127] In the above embodiment, an example has been shown in which two different pieces of biological information, namely blood pressure and cardiac function index, are displayed on the touch panel display 23, but an output related to the internal pressure of the sensing cuff 15 is acquired (an example of the "first information" and "second information" of the present disclosure), and the internal pressure of the sensing cuff 15 (an example of the "first information after the first process related to display is executed" of the present disclosure) and blood pressure information calculated based on the output related to the internal pressure of the sensing cuff 15 (an example of the "second information after the second process related to display is executed" of the present disclosure) may be displayed on the touch panel display 23. In such a case, the calculation of blood pressure based on the output related to the internal pressure of the sensing cuff 15 may be executed in the smartphone 50.
