It is possible that the measurement result of the part becomes the measurement result of another patient. Therefore, it is necessary to confirm the identity of the patient to be measured between the devices of the set of measuring devices.

  In order to solve this problem, in general, a barcode associated with a patient is affixed to each device, and the barcode is read by each device. A method of authenticating identity using biological information such as a palm vein is conceivable. Further, for example, in Japanese translations of PCT publication No. 2005-534378 (hereinafter referred to as Patent Document 1) and Japanese Patent Publication No. 2008-518708 (hereinafter referred to as Patent Document 2), each measuring device specifies an individual using biological information such as a pulse pattern. The method of doing is disclosed.

[First Embodiment]
<Overview of operation>
The biological information monitor 1 is used for each person to be measured or for a plurality of persons to be measured. That is, the biological information of the measurement subject is measured by each of the two or more measuring devices included. At this time, in each measuring device, the biological information to be measured by the measuring device and the biological information used for authentication in the control device 10 are measured. From each measuring device, the biological information to be measured by the measuring device and the biological information used for authentication in the control device 10 are associated and transmitted to the control device 10 wirelessly, and the control device 10 performs authentication processing. Is done. As a result, if the authentication is successful, the control device 10 associates the biological information to be measured with each measuring instrument and transmits the biometric information to the processing device 2.

  In the description of the first embodiment, the pulse rate is used as the biological information used for authentication in the control device 10. However, the biological information used for authentication in the control device 10 is not limited to the pulse rate, and may be other information as long as the biological information has a different value for each individual within a range in which the individual can be identified. As other information, for example, a pulse wave, an electrocardiogram pattern (RR interval), body temperature, impedance, or the like can be used.

  FIG. 6 is a diagram showing an outline of the operation of the biological information monitor 1 according to the first embodiment.

  Referring to FIG. 6, when the operation starts, the patient ID is read by bar code reader 60 in step S01, and the information is sent to sphygmomanometer 20. In step S03, using the sphygmomanometer 20, the blood pressure of the measurement subject is measured as the biological information of the measurement target in the sphygmomanometer 20. In step S05, the blood pressure meter 20 is used to measure the pulse rate of the measurement subject as biometric information for authentication in the control device 10. The sphygmomanometer 20 associates the obtained patient ID, blood pressure value, and pulse rate, and transmits them to the control device 10 in step S07. The blood pressure value and the pulse rate may be transmitted as one data.

  In step S09, the thermometer 30 is used to measure the body temperature of the person to be measured as the biological information to be measured by the thermometer 30. In step S <b> 11, the thermometer 30 is used to measure the pulse rate of the measurement subject as biometric information for authentication in the control device 10. The thermometer 30 associates the obtained body temperature with the pulse rate, and transmits it to the control device 10 in step S13.

  In step S15, using the pulse oximeter 40, the blood oxygen concentration of the measurement subject is measured as the biological information to be measured by the pulse oximeter 40. Moreover, the pulse rate of the said to-be-measured person as biometric information for authentication in the control apparatus 10 is measured using the said pulse oximeter 40 by step S17. The pulse oximeter 40 associates the obtained blood oxygen concentration with the pulse rate and transmits it to the control device 10 in step S19. The blood oxygen concentration and the pulse rate may be transmitted as one data.

The order of measurement using these measuring instruments is not limited to the order shown in FIG.
In step S21, the control device 10 performs an authentication process using information transmitted from each measuring instrument. That is, the control device 10 compares the pulse rate measured as biometric information for authentication by the control device 10 transmitted from each measuring device and obtained from the same subject. By determining whether or not it is a thing, the measurement value obtained by being measured as the biological information of the measurement object by the measurement device by each measurement device is obtained from the same subject. Authenticate that.

  When the authentication in step S21 is successful, that is, when it is authenticated that these pulse rates are obtained from the same person to be measured, the control device 10 is transmitted from each measuring device in step S23. In addition, each measurement value, which is biological information as a measurement target of the measuring instrument, is associated. In step S25, the group of associated measurement values is associated with the patient ID and transmitted to the processing device 2. In step S27, the group of associated measurement values are displayed on the display unit 13 as measurement values of the measurement subject specified by the patient ID.

  The processing device 2 executes management processing for the received measurement value in accordance with the execution of the installed management application 2A (step S29). For example, a process of writing a measurement value in the electronic medical record of the measurement subject corresponding to the associated patient ID is applicable.

<Functional configuration>
The functional configurations of the sphygmomanometer 20, the thermometer 30, and the pulse oximeter 40 as measuring devices are substantially the same as the functional configurations for normal measurement. That is, the sphygmomanometer 20, the thermometer 30, and the pulse oximeter 40 as measuring instruments have a function for performing the following operation.

  By accepting an input of an operation signal for instructing the start of measurement from an operation switch (not shown) or the like, the CPU reads the program stored in the memory, and the measurement operation is performed in the measurement unit. At that time, in each measuring instrument included in the biological information monitor 1, the biological information for authentication in the control device 10 is combined with the biological information to be measured by the measuring instrument according to the program stored in the memory. (Pulse rate in this example) is measured. The CPU stores the measurement value, which is the biological information to be measured by the measuring device obtained by this operation, and the measurement value, which is the biological information for authentication in the control device 10, in the memory. Then, the CPU transmits the associated measurement value to the control device 10 in response to detection of a predetermined timing or a predetermined instruction operation.

  FIG. 7 is a block diagram illustrating a specific example of a functional configuration of the control device 10 according to the first embodiment. Each function shown in FIG. 7 is mainly formed in the CPU 11 when the CPU 11 of the control device 10 reads and executes a program stored in the memory 12. However, at least a part may be formed by a hardware configuration such as an electric circuit.

  Referring to FIG. 7, the control device 10 according to the first embodiment includes a first input unit 101 for receiving input of information transmitted from the sphygmomanometer 20 via the first communication unit 14, and a thermometer. A second input unit 102 for accepting input of information transmitted from 30 via the second communication unit 15, and an accepting input of information transmitted from the pulse oximeter 40 via the third communication unit 16 From the information input from the third input unit 103 and each measuring device, the pulse rate that is the measurement value for authentication in the control device 10 and the measurement value that is the biological information of the measurement target in the measurement device are acquired. An authentication unit 104 for performing authentication using a measurement value for authentication in the control device 10 input from each measuring device, and an input from each measuring device according to an authentication result Biological information to be measured by the measuring instrument A processing unit 105 for performing a process of associating a measurement value, and a display processing unit for executing a process of displaying the associated measurement value on the display unit 13 as the measurement value of the measurement subject specified by the patient ID. 106 and a transmission processing unit 107 for executing processing for transmitting the associated measurement value to the processing device 2 via the fourth communication unit 17 in association with the patient ID.

  The authentication unit 104 stores in advance a variation threshold (for example, ± 5 bpm) as a reference for determining that the pulse rate as the biological information used for authentication in the control device 10 is obtained from the same person to be measured. Keep it. Then, the pulse rate input from each measuring device is compared, and if these values are within the range of variation stored in advance as a threshold value, the pulse rate measured by each measuring device is the same. The pulse rate measured from the person to be measured, that is, the identity of the person to be measured in each measuring device is authenticated.

  When the authentication unit 104 has succeeded in the authentication as described above, the processing unit 105 associates with the pulse rate and inputs a measurement value (blood pressure value) that is biometric information of the measurement target in the measurement device that is input from each measurement device. , Body temperature, and blood oxygen concentration) are related to the blood pressure value, body temperature, and blood oxygen concentration, assuming that they are all obtained from the same person whose pulse rate was measured. Perform processing. As an example of the associating process, there is a process in which a storage area corresponding to the patient ID is provided in the memory 12 in advance, and the associated measurement values are stored in the storage area so as to represent the same measurement timing. Another process includes a process of adding the patient ID transmitted from the sphygmomanometer 20 to each measurement value.

  On the other hand, if authentication is unsuccessful in the authentication unit 104, that is, if even one pulse rate is outside the above-described variation range, the processing unit 105 is input from each measuring device in association with these pulse rates. Assuming that the measurement values (blood pressure value, body temperature, and blood oxygen concentration) that are biological information of the measurement object by the measuring instrument are not measured from the same person, the process of associating these measurement values is not performed. In this case, the display processing unit 106 may perform processing for displaying an error or warning on the display unit 13. In addition to this process, a process for displaying the measurement value on the display unit 13 may be performed. Further, instead of (or in addition to) the display on the display unit 13, in the case of having a speaker or a vibration mechanism, it is not measured by the same person under measurement with a warning sound or a vibration for notifying a warning. You may make it alert | report.

  Preferably, each measuring instrument has a clock function, acquires information specifying the time of measurement when performing a measurement operation, and transmits the information together with the measurement value to the control device 10. The authentication unit 104 performs the above-described authentication using a measurement value for authentication whose measurement time is within a predetermined time. For example, biometric information such as the pulse rate may vary greatly depending on the occurrence of events such as exercise, meals, medications, time zones, and psychological conditions. Therefore, authentication accuracy can be improved by performing authentication using a measured value within a predetermined time (for example, within 15 minutes).

  In this case, the authentication unit 104 may output an error or a warning as an unsuccessful authentication if it is determined that the measurement value for authentication is not measured within the predetermined time. .

<Operation flow>
FIG. 8 is a flowchart showing the operation of the control device 10 according to the first embodiment. The operation shown in the flowchart of FIG. 8 is realized by causing the CPU 11 of the control device 10 to read out and execute a program stored in the memory 12 to exhibit each function shown in FIG. 9 to 11 are diagrams illustrating screen examples displayed on the display unit 13 in accordance with the operation of the control device 10.

Referring to FIG. 8, CPU 11 stands by for input of measurement values from each measuring instrument.
At this time, when the patient ID previously input together with the measurement value is stored in the memory 12, the CPU 11 assumes that the measurement value associated with the patient ID is input next, as shown in FIG. It is also possible to display a screen (unmeasured) indicating that each measurement value corresponding to the patient ID (000012) input together with the measurement value has not been input yet.

  When it is detected that a measurement value has been received from each measuring instrument (YES in step S101), in step S102, the CPU 11 acquires a measurement value for authentication from the input measurement value. And CPU11 performs an authentication process using the measured value for authentication. That is, the CPU 11 compares the pulse rate measured by each measuring instrument and determines whether or not these are within a predetermined variation range stored in advance, thereby obtaining the same measurement subject. It is determined whether or not it is a measured value.

  As a result of authentication, if all the pulse rates input from each measuring device are within the range of variation prescribed in advance (YES in step S103), the CPU 11 has the same measured value in each measuring device. It is a measurement value obtained from the measurement subject, that is, the identity of the measurement subject of each measuring device is authenticated, and the blood pressure value, body temperature, and blood oxygen concentration input from these measuring devices in step S105 are obtained. Execute the process for associating. Here, as an example, a process of storing these measurement values in a storage area prepared in advance in the memory 12 corresponding to the patient ID corresponds. Moreover, as another process, the process which adds patient ID input from the sphygmomanometer 20 to each measured value may be sufficient.

In step S107, the CPU 11 displays the associated measurement value on the display unit 13 as the measurement value of the measurement subject corresponding to the patient ID. FIG. 10 shows a specific example of the screen in the case of successful authentication, and the patient ID (000012) input in association with the blood pressure value is associated with the blood pressure value, body temperature, and blood oxygen concentration (SpO ₂ ). Displayed on a single screen.

  Preferably, the CPU 11 also displays the pulse rate on the screen. This pulse rate may be the pulse rate input from any of the measuring devices, or the pulse rate values from a plurality of measuring devices such as the average value of the pulse rate input from each measuring device may be processed. It may be obtained.

  Further, when the correspondence between the patient ID and the information (for example, name) for specifying the person to be measured is stored in the memory 12 in advance, the CPU 11 displays the measurement value together with the information for specifying the person to be measured corresponding to the patient ID. You may let them.

  In step S109, the CPU 11 transmits the associated measurement value to the processing device 2 in association with the patient ID.

  On the other hand, if the authentication is unsuccessful, that is, if one of the pulse rates input from each measuring device is not within the predetermined variation range stored in advance (in step S103). NO), the CPU 11 determines that the measurement value input from each measuring instrument includes a measurement value that is not obtained from the same person to be measured. In step S111, the CPU 11 A warning is displayed on the display unit 13. FIG. 11 shows a specific example of the screen in the case of unsuccessful authentication, and a message indicating that the pulse rate from each measuring device does not match is displayed.

  As a case where the authentication is unsuccessful, for example, when any one of the sphygmomanometer 20, the thermometer 30, and the pulse oximeter 40 is used to measure the biological information of the measurement subject different from the other measuring devices. Is mentioned. In this case, the measurement value input to the control device 10 is not obtained from the same person to be measured.

  In another case, a plurality of the biological information monitors 1 exist and are used for different persons to be measured, and the second measuring device used for the measurement of the first person to be measured is the second one. A case where the measured value is transmitted by mistake to the control device 10 of the biological information monitor 1 used for the measurement subject is mentioned. In particular, since the control device 10 and each measuring device perform wireless communication, there is a possibility that a measurement value is transmitted to a control device included in another biological information monitor. Therefore, the screen shown in FIG. 11 is used for confirming whether or not the measuring instrument has been mixed, that is, whether or not the measurement value is transmitted from the measuring instrument included in the same biological information monitor as the control device 10. A message is displayed.

In addition to this display, the blood pressure value, body temperature, and blood oxygen concentration (SpO ₂ ) input from each measurement value are displayed together with the patient ID (000012) input in association with the blood pressure value. Also good. In this way, it is possible to check the measured value even if there is an error.

<Effect of the first embodiment>
By performing such an operation in the biological information monitor 1 according to the first embodiment, a plurality of measuring devices included in the biological information monitor 1 are used independently of the control device 10 to measure biological information. When the result is transmitted to the control device 10, the measured value from each measuring device can be authenticated and correlated as the measured value measured from the same person to be measured.

  At this time, by performing authentication using the measurement value for authentication measured by each measuring device, the configuration for reading the identification information (patient ID) of the measurement subject (patient ID) by each measuring device and the operation for reading are unnecessary. It can be authenticated with accuracy.

[Second Embodiment]
<Overview of operation>
In the second embodiment, the control device 10 controls the measurement operation in each measuring instrument. That is, in the biological information monitor 1 according to the second embodiment, at the start of measurement, each measuring instrument measures at least a measurement value that is biometric information for authentication and transmits it to the control device 10. When the control device 10 succeeds in authenticating the identity of the person to be measured at each measuring device using these measured values, the control device 10 provides the biological information that is the measurement target of the measuring device to each measuring device. Instruct the start of measurement.

  In the description of the second embodiment, the pulse rate is used as the biological information used for authentication in the control device 10. However, the biological information used for authentication in the control device 10 is not limited to the pulse rate, and if the biological information has different values for each individual within a range where the individual can be identified, the pulse wave or the electrocardiographic pattern (RR) Other information such as interval), body temperature, and impedance may be used.

  FIG. 12 is a diagram illustrating an outline of operation in the biological information monitor 1 according to the second embodiment.

  Referring to FIG. 12, when the operation starts, the patient ID is read by bar code reader 60 in step S31, and the information is sent to sphygmomanometer 20. In step S33, using the blood pressure monitor 20, the pulse rate of the measurement subject as biometric information for authentication in the control device 10 is measured. The sphygmomanometer 20 associates the obtained patient ID and pulse rate, and transmits them to the control device 10 in step S35.

  In step S <b> 37, using the thermometer 30, the pulse rate of the measurement subject as biometric information for authentication in the control device 10 is measured. The thermometer 30 transmits the obtained pulse rate to the control device 10 in step S39.

  In step S41, using the pulse oximeter 40, the pulse rate of the measurement subject as biometric information for authentication in the control device 10 is measured. The pulse oximeter 40 transmits the obtained pulse rate to the control device 10 in step S43.

  At this time, along with the measurement of the pulse rate in steps S33, S37, and S41, the biological information that is the measurement target of the measuring device may be measured and transmitted to the control device 10 together with the pulse rate.

  In step S45, the control device 10 compares the pulse rate transmitted from each measuring device, and determines whether or not these are obtained from the same person to be measured. Authenticate the identity of the person. The authentication here is the same as the authentication in the control device 10 according to the first embodiment.

  When the authentication in step S45 is successful, in step S47, the control device 10 transmits a command (control signal) for instructing measurement of biological information to be measured by the measurement device to each measurement device.

  In accordance with a command from the control device 10, each measuring instrument performs an operation of measuring biological information to be measured by the measuring instrument (steps S49, S51, and S53), and the measurement values obtained in step S55 are measured. It is transmitted from the measuring instrument to the control device 10.

  In step S57, the control device 10 associates each of the measurement values transmitted from the respective measuring devices, and in step S59, the group of these associated measurement values previously transmitted from the sphygmomanometer 20 together with the pulse rate. The data is transmitted to the processing device 2 in association with the ID. In step S61, the group of associated measurement values are displayed on the display unit 13 as measurement values of the measurement subject specified by the patient ID.

  The processing device 2 executes management processing for the received measurement value in accordance with execution of the installed management application 2A (step S63).

<Functional configuration>
The functional configurations of the sphygmomanometer 20, the thermometer 30, and the pulse oximeter 40 as measuring devices are substantially the same as the functional configuration of normal measurement, like the biological information monitor 1 according to the first embodiment. However, in the biological information monitor 1 according to the second embodiment, each measuring device receives a command from the control device 10 and starts an operation of measuring biological information that is a measurement target in the measuring device according to the command. It has a different function.

  FIG. 13 is a block diagram illustrating a specific example of a functional configuration of the control device 10 according to the second embodiment. Each function shown in FIG. 13 is mainly formed in the CPU 11 when the CPU 11 of the control device 10 reads and executes a program stored in the memory 12. However, at least a part may be formed by a hardware configuration such as an electric circuit.

  Referring to FIG. 13, the control device 10 according to the second embodiment performs measurement for each measuring instrument in addition to the function of the control device 10 according to the first embodiment shown in FIG. A control unit 109 for outputting a command (control signal) for instructing and controlling a measurement operation in each measuring instrument is included. The control unit 109 outputs the above command to each measuring device when the authentication by the authentication unit 104 is successful, and does not output when the authentication is unsuccessful.

<Operation flow>
FIG. 14 is a flowchart showing the operation of the control device 10 according to the second embodiment. The operation shown in the flowchart of FIG. 14 is realized by causing the CPU 11 of the control device 10 to read out and execute a program stored in the memory 12 to exhibit each function shown in FIG.

  The operation of the control device 10 according to the second embodiment shown in FIG. 14 is compared with the operation of the control device 10 according to the first embodiment shown in FIG. 8 in steps S103 and S105. A difference is that an operation of outputting a command to each measuring device and receiving an input of a measured value from each measuring device is added during the operation.

  Specifically, referring to FIG. 14, the control device 10 according to the second embodiment compares the pulse rate input from each measuring device and authenticates that they are within a predetermined range. If it is determined (YES in step S103), in step S201, the CPU 11 transmits a command instructing the start of the measurement operation of the biological information to be measured by the measurement device to each measurement device. And it waits for the input of the measured value from each measuring device.

  When an input of a measurement value is received from each measuring device operated according to the above command (YES in step S203), in step S105, the CPU 11 associates the blood pressure value, body temperature, and blood oxygen concentration input from these measuring devices. Execute the process.

Thereafter, processing similar to that of the control device 10 according to the first embodiment is executed.
<Effects of Second Embodiment>
By performing such an operation in the biological information monitor 1 according to the second embodiment, the biological information monitor 1 performs each measurement after the identity of the person to be measured of each measuring device included is authenticated. Measurement operation on the instrument is started. As a result, for example, when measurement is continuously performed with each measuring device at short time intervals, the continuous measurement operation can be started with the success of authentication as a trigger. In this way, it is not necessary to perform authentication for each measurement, and the processing can be facilitated in the case of such continuous measurement.

  In the operation outline shown in FIG. 12, the pulse rate is measured with the sphygmomanometer 20 (step S33), the pulse rate is measured with the thermometer 30 (step S37), and the pulse rate is measured with the pulse oximeter 40. An example is shown in which (Step S41) is performed in this order in time series. Needless to say, these measurement orders are in the order shown in FIG.

  If they are performed at the same time, the control device 10 determines that the authentication is unsuccessful in the authentication process in step S45 if the at least one pulse rate does not fall within the above-defined variation range. Do not send commands. Therefore, in this case, measurement with each measuring instrument is not started.

  As shown in FIG. 12, when the pulse rate is measured in time series, the control device 10 accepts the input of the pulse rate from all the measuring instruments as shown in FIGS. After that, the authentication process may be performed, or when the input of the pulse rate from the two measuring devices is received, the authentication process may be started using the two pulse rates.

  In the latter case, for example, in the example of FIG. 12, when the input of the pulse rate from the sphygmomanometer 20 and the input of the pulse rate from the thermometer 30 are received, these pulse rates are compared, and the above-mentioned pre-defined It is determined whether it is within the range of variation. Thereafter, an authentication process is performed each time an input of the pulse rate is received. At this time, if it is determined by the previous authentication process that the pulse rate is more than the prescribed value, that is, if the authentication is unsuccessful, the subsequent authentication process can be made unnecessary. That is, in the example of FIG. 12, when authentication using the pulse rate at the time of receiving the input of the pulse rate from the sphygmomanometer 20 and the input of the pulse rate from the thermometer 30 is unsuccessful, Authentication can be made unsuccessful without waiting for the input of the pulse rate from the next pulse oximeter 40. At that time, a command is not transmitted to each measuring instrument, that is, a measuring operation is performed using these measuring instruments. It can be determined that there is no. By performing the authentication process in this way, the time required for the authentication process can be shortened, and the authentication result can be notified quickly.

[Modification 1]
As a method of using the biological information monitor 1 and the processing device 2, the biological information monitor 1 is provided at the measurement subject's home, the processing device 2 is provided at a medical institution, and the control device 10 and the processing device 2 are, for example, the Internet. It is assumed that the measured value of the measurement subject stored in the memory 12 of the control device 10 is read using the processing device 2 in a medical institution. This corresponds to a case where a person to be measured measures daily biological information at home and makes a remote determination using the measured value at a medical institution far away.

  In this case, as an example, the processing device 2 transmits a transmission request including the patient ID to the control device 10, and the control device 10 that has received the request receives a group of associated groups corresponding to the patient ID. The above-described usage is realized by transmitting the measurement value to the processing device 2.

  By the way, as another example, a measuring device 70 is connected to the processing device 2 (provided in a medical institution), and a measurement person who visits the medical institution uses the measuring device 70 to measure, It is assumed that the measurement value stored in the memory 12 of the control device 10 is read. The measuring device 70 may be any measuring device such as a sphygmomanometer, a thermometer, or a pulse oximeter, or all of them. At this time, if the measurement value is requested by the patient ID as described above, the measurement subject, the doctor, or the like needs to input the patient ID to the processing device 2. Therefore, as a modification, an example in which a measurement value is easily transmitted from the control device 10 to the processing device 2 using the above-described authentication processing will be described.

  Assuming that the above-described authentication of whether or not the measurement subject in each measuring device in the control device 10 is the same as the first authentication, the control device 10 according to the modified example performs processing in addition to the first authentication. The second authentication is performed when transmitting to the device 2. The second authentication process is the same as the first authentication process.

  FIG. 15 is a diagram illustrating a specific example of the configuration of the biological information monitor 1 according to the modification. With reference to FIG. 15, in the modification, a measuring device 70 is connected to the processing device 2, and a measurement value at the measuring device 70 is transmitted from the measuring device 70 to the processing device 2. The measuring device 70 may be any measuring device such as a sphygmomanometer, a thermometer, or a pulse oximeter, or all of them. This measuring device 70 has the same function as the measuring device included in the biological information monitor 1 for measuring authentication biometric information, that is, the function of measuring the pulse rate in the above example.

  When the processing device 2 requests the control device 10 to transmit a measurement value, the processing device 2 transmits a measurement value including a pulse rate which is biometric information for authentication measured by the measuring device 70. In the control device 10, the pulse rate which is the measurement value for authentication is stored in the memory 12 together with the measurement value from each measuring device, and the pulse rate included in the request and the pulse rate stored in the memory 12 are defined in advance. Second authentication for authenticating whether or not these measured values are obtained from the same person to be measured by determining whether or not the measured values are within a range of variation (for example, ± 5 bpm). To do.

  If the second authentication is successful, the control device 10 transmits the associated measurement value stored in the memory 12 to the processing device 2.

  By doing in this way, the operation value which inputs patient ID can be made unnecessary and the measured value in which the to-be-measured person is the same can be obtained from the control apparatus 10 in the processing apparatus 2.

[Modification 2]
In the above description, it is assumed that the biological information monitor 1 includes the control device 10. However, the control apparatus 10 may be incorporated in any measuring instrument. That is, any one of the measuring devices may function as the control device 10. As an example, a case where the sphygmomanometer 20 functions as the control device 10 is assumed.

  In this case, the sphygmomanometer 20 stores the measured value (blood pressure value) and the pulse rate measured by itself, and from the thermometer 30 and the pulse oximeter 40, the body temperature and the pulse rate, and the blood oxygen concentration and the pulse rate, respectively. , And using the pulse rate measured by itself and the input pulse rate, it is authenticated that these are measured from the same person to be measured.

  At this time, by using human body communication for the communication between the sphygmomanometer 20 and the thermometer 30 and the communication between the sphygmomanometer 20 and the pulse oximeter 40, each measuring instrument is used for measurement by the subject. The measurement value is transmitted to the sphygmomanometer 20 in the mounted state, and temporal synchronization can be confirmed.

[Modification 3]
In the above description, a measurement value as biological information is used to authenticate that a person to be measured in each measuring instrument is the same person to be measured. In the example above, the pulse rate is used. Further, it is not limited to the pulse rate, and it may be biological information having different values within a range that can be identified for each individual.

  Here, as still another example, communication between each measuring device and the control device 10 (in the case of Modification 2, communication between the measuring device having the function of the control device 10 and another measuring device). When human body communication is used, the resistance value of the human body communication may be used as biometric information for authentication. This is because the resistance value of human body communication changes depending on the tissue of the human body, and the value varies within a range that can be identified for each individual. That is, the resistance value of the human body communication is also included in the biological information because it depends on the living body.

  Furthermore, it is possible to provide a program for causing the control device 10 configured by a general personal computer to execute the above-described processing. Such a program is stored in a computer-readable recording medium such as a flexible disk attached to the computer, a CD-ROM (Compact Disk-Read Only Memory), a ROM (Read Only Memory), a RAM (Random Access Memory), and a memory card. And can be provided as a program product. Alternatively, the program can be provided by being recorded on a recording medium such as a hard disk built in the computer. A program can also be provided by downloading via a network.

  The program according to the present invention is a program module that is provided as a part of a computer operating system (OS) and calls necessary modules in a predetermined arrangement at a predetermined timing to execute processing. Also good. In that case, the program itself does not include the module, and the process is executed in cooperation with the OS. A program that does not include such a module can also be included in the program according to the present invention.

  The program according to the present invention may be provided by being incorporated in a part of another program. Even in this case, the program itself does not include the module included in the other program, and the process is executed in cooperation with the other program. Such a program incorporated in another program can also be included in the program according to the present invention.

  The provided program product is installed in a program storage unit such as a hard disk and executed. The program product includes the program itself and a recording medium on which the program is recorded.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
