Description

This application relates to a biological information measurement system that acquires biological information of a subject over a certain period of time using a small measurement terminal attached to the subject, and grasps changes in the biological information. The present invention relates to a biological information measurement system capable of easily determining whether or not a

2. Description of the Related Art A biological information measurement system is known that continuously grasps biological information of a measurement subject for a certain period of time, for example, several days to two weeks. In such a biometric information measurement system, biometric data including measured values of biometric information and the measurement time when the biometric information was acquired from a measurement terminal worn by a person to be measured and acquiring biometric information manages the entire system. sent to the management device that The management device records and analyzes the acquired biometric data, and performs various processes such as issuing a warning regarding the health condition of the measurement subject based on the biometric data as necessary.

In order to reduce the burden on the measurement subject who wears the measurement terminal for a long time, it is preferable that the measurement terminal be small and lightweight. Moreover, it is preferable that the biometric data measured by the measuring terminal is transmitted to the management device by wireless communication instead of by wire. At this time, in order to simplify the configuration of the data transmission unit of the measurement terminal and reduce the power supply capacity of the measurement terminal, the biometric data is not transmitted directly from the measurement terminal to the management device, but rather is carried separately, and biometric data is transmitted from the measurement terminal to the management device via the main device.

From the measuring terminal, the identification ID of the measuring terminal itself (measurement terminal information) is also transmitted to the management device together with the biometric data. It is possible to determine which subject's data belongs to.

If the measurement terminal is attached to a person other than the original measurement subject during the period of measuring the biological information, the biological information of the original measurement subject cannot be continuously obtained. In order to avoid such an unforeseen situation, a biological information measurement system using a measurement terminal capable of automatically detecting that a different person has worn the device from changes in shape has been proposed (see Patent Document 1). In the biological information measurement system of Patent Document 1, a wristwatch type measurement terminal is used to determine the length of the watch band when worn, and when the length of the watch band changes during the acquisition of biological information. is set to determine that a different person has worn the measurement terminal and issue a warning.

JP-A-2004-166896

The conventional biological information measurement system described in Patent Document 1 makes it possible to determine whether or not the measurement subject has changed depending on the length of the watch band, for example, in the case of a measurement terminal shared by a plurality of measurement subjects. be able to. By using this, if the same person to be measured continues to wear the device, the trouble of inputting identification information for identifying the person to be measured is eliminated, and if a different person to be measured wears it, the identification information is input again. By doing so, it is possible to achieve both simple operation of the system and acquisition of correct data.

However, in the case of measuring the body temperature inside clothes, or in a biometric information acquisition system that continuously obtains biometric information while bathing or exercising, instead of a wristwatch-type measurement terminal, an adhesive sheet is attached to the subject's skin. A so-called patch type measuring terminal is used. Since the shape of the patch-type measuring terminal does not change depending on the body shape of the wearer, it is difficult to detect the change of the person to be measured from the shape change of the measuring terminal, unlike the conventional wristwatch-type measuring terminal. In addition, even in the case of a wristwatch-type measurement terminal, if the length of the watch band when worn by the measurement subject happens to be the same, the shape of the measurement terminal itself does not change even if the wearer changes between the measurement subjects. There is a high possibility that it will not be possible to determine that the subject of measurement has changed.

The purpose of the present application is to solve the problems of the above-described conventional technology. It is an object of the present invention to provide a biological information measurement system capable of easily determining whether or not the measurement results are those of a person to be measured whose biological information data should be acquired.

With the above configuration, in the biological information measurement system disclosed in the present application, the management device acquires the measurement terminal information and the main device information together with the biological information. Therefore, when the combination of the measuring terminal information and the main device information is different from the regular one, it is immediately recognized and recorded with an identification flag added to the obtained biometric information. In this way, by adding an identification flag to the sent data of the biometric information acquired by a measuring terminal other than the measuring terminal registered for the main device owned by the measurement subject, can take measures such as excluding the relevant data during data processing or warning the person being measured through the main device.

[Structure of each part]
FIG. 1 is a block diagram showing a configuration example of each part of the body temperature measurement system according to this embodiment.

Note that FIG. 1 shows a thermometer 10, which is a measurement terminal, a smartphone 20, which is a main device, and a cloud server 30, which is a management device, which are included in the body temperature measurement system according to the present embodiment, from the viewpoint of their operation contents and functions. The constituent members are described as blocks. Therefore, each block shown in FIG. 1 does not represent a physical configuration, for example, a configuration of circuit elements for realizing each function. For example, a block shown as one component in FIG. 1 may be composed of a plurality of circuit blocks, which may be distributed on different circuit boards in some cases. Also, there may be a case where a plurality of blocks shown in FIG. 1 are realized by one circuit element.

(thermometer)
The thermometer 10 includes a biological information measuring unit 11 that measures the body temperature of the person to be measured, a reference clock 12 that outputs a clock signal that serves as a reference for time information inside the thermometer 10, and a person to be measured obtained by the biological information measuring unit 11.

FIG. 2 is an exploded perspective view for explaining the configuration of the thermometer of the body temperature measurement system according to this embodiment.

Also, FIG. 3 is a schematic diagram for explaining the relationship between the members of the thermometer of the body temperature measurement system according to the present embodiment, focusing particularly on the operational aspect.

Furthermore, FIG. 4 is an image diagram showing a state in which a person to be measured is wearing the thermometer of the body temperature measurement system according to the present embodiment.

The thermometer 10 of the body temperature measurement system according to this embodiment is placed in close contact with the body surface of the person 40 to be measured. In addition, since the device will be worn by the person to be measured 40 for a measurement period of, for example, two weeks, it is strongly required to be small and light so as not to burden the person to be measured 40 . Furthermore, even when the thermometer 10 is exposed to water or moisture due to the person 40 being measured taking a bath or sweating, the thermometer 10 is waterproofed so that it can operate normally and measure the body temperature. It has been subjected.

As shown in the exploded perspective view of FIG. 2, the thermometer 10 has an outer shell composed of an upper housing 1 and a lower housing 2 made of resin such as polypropylene, and a circuit board 3 is mounted inside the outer shell. With the battery 6 installed, the connecting portion between the upper housing 1 and the lower housing 2 is ultrasonically crimped to keep the interior watertight. The thermometer 10 shown in FIG. 2 has an outer diameter of 22 mm and a thickness of 4.5 mm.

The body temperature measurement unit, which is the biological information measurement unit 10 provided in the thermometer 10, thermally detects a chip-type temperature sensor 4 arranged on the substrate 3, the temperature sensing unit of the temperature sensor 4, and the body surface of the person to be measured 40. It is composed of a metal terminal 5 connected to the . 2 of the metal terminal 5 is embedded in an opening of the same diameter formed in the lower housing 2, and the lower end surface of the metal terminal 5 is the lower surface of the lower housing 2. , and the lower end surface of the metal terminal 5 is in direct contact with the skin of the person 40 to be measured when the thermometer 10 is worn on the body surface of the person 40 to be measured. Moreover, heat transfer grease (not shown) is applied between the metal terminal 5 and the temperature sensor 4 so that the temperature of the metal terminal 5 can be detected more reliably by the temperature sensor 4 .

In the body temperature measurement system according to the present embodiment, the measured value of the body temperature of the person to be measured 40 measured by the thermometer 10 is associated with the measurement timing data, which is time information indicating the time of measurement, to form biological data. Time information in the thermometer 10 is generated by a reference clock 12 composed of a crystal oscillator.

As the crystal oscillator used for the reference clock 12, for example, a widely used 32 MHz type crystal oscillator can be preferably used. As will be described later, in the body temperature measurement system of the present embodiment, wireless communication between the thermometer 10 and the smartphone 20 is performed using the Bluetooth (registered trademark; this note is omitted hereinafter) standard. Therefore, it is preferable to use the reference clock 12 having an accuracy within ±50 ppm corresponding to the Bluetooth standard.

The biological data generating unit 13 generates the measured value of the body temperature of the person to be measured 40, which is the biological information acquired by the biological information measuring unit 11, and the measurement timing data, which is time information indicating the time when the measured value was acquired. Body temperature data, which is biometric data, is generated by linking them. In the body temperature measurement system according to the present embodiment, the elapsed time from the previous body temperature measurement, that is, the time information representing the body temperature measurement interval is used as the measurement timing data as the time information associated with the measured body temperature.

Body temperature data is timing data, which is the interval between the measured body temperature at that time and the previous measurement, that is, the elapsed time from the previous measurement, every time the body temperature of the person being measured is measured. are connected and generated. The generated biometric data are sequentially stored in the storage unit 16 .

In the body temperature measurement system according to the present embodiment, intervals for measuring the body temperature of the person to be measured are determined in advance. Basic body temperature measurement intervals are set to relatively long intervals such as 30 minutes, 1 hour, 2 hours, and the like, for example. However, for example, when it is assumed that the subject's physical condition has deteriorated, the body temperature measurement interval can be set to 15 minutes, 10 minutes, 5 minutes, 1 minute, etc. Depending on the purpose, the setting is changed to a shorter measurement interval as appropriate. The measurement interval change unit 14 changes the body temperature of the measurement subject obtained as a measurement result, for example, when the body temperature of the measurement subject increases, for example, when it exceeds 36.8°, the measurement interval of the body temperature is changed. If necessary, set multiple thresholds and change the body temperature measurement interval in stages, such as shortening the first stage and shortening the measurement interval by another stage if the body temperature exceeds 37.5°. can do. In addition, when the body temperature of the person being measured falls below the threshold, the measurement interval changing unit 14 may change the body temperature measurement interval to be longer, such as returning to the initially set measurement interval. can.

Control unit 15 controls the operation of each circuit component mounted on thermometer 10 . The control unit 15 can be configured as a microcomputer in the form of an IC chip (microcomputer) or as an assembly of various arithmetic circuit elements.

The storage unit 16 stores body temperature data generated by the biological data generation unit 13 . In addition, the storage unit 16 stores information such as an initial setting measurement interval for the biological information measurement unit 11 to measure the body temperature of the measurement subject and a threshold value that is a reference for changing the measurement interval in the measurement interval change unit 14. Data referred to by the control unit 15 and each operation circuit unit when the operation is performed is stored. For the storage unit 16 used in the thermometer 10, which is required to be small and light, it is not preferable to increase the capacity too much. can also use flash memory. In addition, in order to keep the data volume of the storage unit 16 small, after the body temperature data in the storage unit 16 is transmitted by data communication between the thermometer 10 and the smartphone 20, all the transmitted old body temperature data are deleted. It is preferable to perform such operation control. Further, the storage unit 16 stores a thermometer ID (measurement terminal information), which is its own identification information.

The thermometer 10 of the body temperature measurement system according to the present embodiment uses Bluetooth as means for short-range wireless communication with the smartphone 20, which is the main device. Therefore, the data transmission unit 17 and the data reception unit 18 of the thermometer 10 are transmission/reception units complying with the Bluetooth standard.

When the wireless communication connection based on the Bluetooth standard with the smartphone 20 is established, the control unit 15 transmits all body temperature data stored in the storage unit 16 from the data transmission unit 17 to the smartphone 20 . At this time, from the information of the reference clock 12, the control unit 15 grasps the time of data transmission and the elapsed time from the measurement of the body temperature of the person to be measured immediately before that time, and similarly from the data transmission unit 17 Send to the smart phone 20 . Also, the thermometer ID stored in the storage unit 16 is transmitted.

As shown in FIGS. 2 and 3, the thermometer 10 has a button-type battery 6 as its operating power supply. As the battery 6, in addition to a button-type primary battery, for example, an air battery or a rechargeable secondary battery can be used. Therefore, in the case of the thermometer of this embodiment in which the upper and lower housings 1 and 2 are waterproofed and sealed, it is necessary to separately provide an air hole to prevent moisture from entering. In addition, by using a secondary battery, the thermometer 10 can be used repeatedly. Therefore, it is more preferable to use the button type primary battery as exemplified above rather than the secondary battery.

As shown in FIG. 3, the thermometer 10 according to this embodiment has phototransistors 7 arranged inside upper and lower housings 1 and 2 . At least one of the housings 1 and 2 is made of a resin member having a certain level of translucency, such as polypropylene, as described above, and the phototransistor 7 is provided inside, so that the phototransistor 7 emits light. When detected, the electric circuit inside the thermometer 10 is caused to start operating. In addition, by sealing and storing the thermometer 10 inside the laminate film 60 or the like, which is a member that does not transmit light, immediately after manufacturing, the operation of the thermometer 10 is minimized until it is removed from the laminate film 60 at the start of use. can be effectively avoided from being exhausted before the thermometer 10 is actually used.

The thermometer 10 is worn so that the metal terminals 5 are in contact with the skin of the subject 40 to be measured. In order to keep the thermometer 10 in contact with the epidermis of the person to be measured in the same state during a predetermined temperature measurement period, the whole thermometer 10 is covered with an adhesive tape 50 such as medical surgical tape, and the person 40 to be measured is covered. It is preferable to attach the Since the thermometer 10 has a predetermined size of 22 mm in diameter, it is difficult to measure the deep body temperature of the person to be measured 40, but the thermometer 10 should be attached to a part that is not exposed to the outside air as much as possible. is preferred. From this point of view, the place where the thermometer 10 is worn should be a place where the temperature inside the clothes of the person to be measured 40 can be detected and where the person to be measured is unlikely to feel discomfort due to wearing the thermometer 10. , The area from the chest to the flank is preferable as a place where the movement of the epidermis is relatively small.

FIG. 4 shows an image diagram of a state in which a person to be measured is wearing a thermometer.

(smartphone)
Returning to FIG. 1, in the body temperature measurement system of this embodiment, a smartphone 20 is used as a main device that receives data from a thermometer 10, which is a measurement terminal.

The smartphone 20 as a main device has functions as a mobile phone, and includes a current time acquisition unit 21 that acquires the current time, an image display device such as a liquid crystal panel or an organic EL panel, and a processing circuit that performs data processing of an image to be displayed. image display unit 24 including application software used, photos, voice, storage unit 25 such as RAM and CPU cache memory for storing communication records such as e-mails, data transmission unit 26 for carrier communication, data reception a portion 27; In the body temperature measurement system of the present embodiment, as described above, data is transmitted and received between the thermometer 10, which is the measurement terminal, and the smartphone 20, which is the main device, based on the Bluetooth standard. Mutual communication with other Bluetooth devices is also executed by the functions of the data transmitting section 26 and the data receiving section 27 .

Of the body temperature data transmitted from the thermometer 10 when data communication with the thermometer 10 is established, the measurement result data generation unit 22 converts the measurement timing data, which is time information indicating when the body temperature was measured, to the previous measurement. The information indicating the measurement interval from time is converted into measurement result data replaced with time information indicating the actual measurement time at which the body temperature was measured. Data conversion from body temperature data to measurement result data is performed by application software that is installed in smartphone 20 and controls the body temperature measurement system shown in this embodiment, and the converted measurement result data is sequentially stored in storage unit 25 of smartphone 20. remembered.

The storage unit 25 further stores a smartphone ID (main device information) that is identification information of the smartphone 20 itself, which is a main device.

The timing data calibration section 23 verifies the clock frequency of the reference clock 12 of the thermometer 10 based on the measurement result data generated by the measurement result data generation section 22 . Then, if there is an error in the clock frequency, calibration data for calibrating this error is created. The calibration data is transmitted from the data transmission unit 26 to the data reception unit 18 of the thermometer 10 through Bluetooth standard communication, and the control unit 15 of the thermometer 10 receives measurement timing data as time information recorded in body temperature data obtained thereafter. is calibrated using the calibration data. The function of the timing data calibration unit 23 is also executed by application software compatible with the body temperature measurement system according to this embodiment.

The smartphone 20 displays on the image display unit 24 of the smartphone 20 that data communication based on the Bluetooth standard has been established with the thermometer 10 and that the biometric data recorded in the storage unit 16 has been successfully transmitted and received from the thermometer 10 . , and can be notified to the person to be measured 40 or the supervisor who manages the data.

In the body temperature measurement system according to the present embodiment, the smartphone 20 transmits the measurement result data including the biological information acquired from the person to be measured and the time data at which the biological information was acquired to the cloud server 30 which is a management device. Send. In the biological information measurement system of the present embodiment, since the smartphone 20 is used as the main device, the data transmission unit 26 of the carrier communication means provided in the smartphone 20 is used as it is, and the cloud server 30 installed on the Internet line is used. Measurement result data can be transmitted.

(cloud server)
The cloud server 30 as a management device receives body temperature information, which is biological information of all measurement subjects registered in the body temperature measurement system shown in the present embodiment, via the Internet line, and uses its own function as a computer. Data recording and data processing using the recorded data are centrally performed.

In the body temperature measurement system according to the present embodiment, the data processing function of the cloud server 30 is used to process the data received from the smartphone 20 by the processing unit 31, and the acquired body temperature measurement value represents the body temperature of the regular measurement subject. The judgment unit 32 for judging whether or not the thermometer 10 is correct, generates caution information to warn the person to be measured to wear the correct thermometer 10 when it is considered that the body temperature of the person to be measured cannot be measured properly. and an information generator 33 . In addition, a control unit 34 that controls everything such as data reception and transmission, data processing and data recording, and acquisition of necessary external information executed by the cloud server 30, various data, acquired information, data processing results, etc. A storage unit 35 for storing is provided. Also, through the Internet environment, a data transmission unit 36 that transmits various data to the smartphone 20 and other external management organizations, measurement result data and ID information transmitted from the smartphone 20, environmental data and statistical data from external organizations and a data receiving unit 37 for receiving processing standards for performing various data processing.

[Processing of measurement result data]
Next, in the body temperature measurement system according to the present embodiment, the processing of measured value data of the body temperature of the subject measured by the thermometer 10 will be described. In the body temperature measurement system according to the present embodiment, the measured values of body temperature are collected from the thermometer 10, which is a biological information acquisition terminal, and the data of the measurement results are aggregated and sent to the cloud server 30, which is a management device that performs processing such as data analysis. In the transmission process, the thermometer ID, which is the identification information of the thermometer 10, and the smartphone ID, which is the identification information of the smartphone 20, are used to ensure that the measured body temperature transmitted from the thermometer 10 to the smartphone 20 is correctly the original measurement target. Determine whether it was obtained as a result of measuring the body temperature of a person.

FIG. 5 is a flowchart for explaining data processing in each part of the system for the measured body temperature, which is biological information obtained from a person to be measured, in the body temperature measurement system described in this embodiment.

As described above, for example, when the thermometer 10 is taken out of the package of the laminate film 60, the phototransistor 7 detects light, the thermometer 10 is activated, and measurement of the body temperature of the subject is started (START).

The controller 15 of the thermometer 10 reads the numerical value of the temperature sensor 4 at predetermined measurement intervals such as 30 minutes (step S01). At the same time, the control unit 15 acquires timing data indicating the measurement timing at which the body temperature was read (step S02).

The body temperature data generator 13 of the thermometer 10 combines the body temperature measurement value and the timing data to generate body temperature data (step S<b>03 ), which is sequentially accumulated in the storage unit 16 .

When Bluetooth standard communication is established between the thermometer 10 and the smartphone 20 and preparations are made to transmit body temperature data from the thermometer 10 to the smartphone 20, the control unit 15 retrieves the thermometer ID, which is its own identification information, from the storage unit 16. is called (step S04), and is transmitted to the smartphone 20, which is the main device, together with the plurality of pieces of body temperature data stored in the storage unit 16 (step S05).

The smartphone 20 receives the body temperature data and the thermometer ID transmitted from the thermometer 10 (step S11).

The current time acquisition unit 21 of the smartphone 20 acquires time information acquired using a clock function provided in the smartphone 20 itself or an application, and obtains body temperature data based on the time when the body temperature data or the like is received from the thermometer 10. is converted into time information indicating the measured time (step S12). At this time, if the smartphone 20 detects from the timing data that there is an error in the clock frequency of the reference clock 12 of the thermometer 10, the timing data calibration unit 23 creates calibration information for calibrating the timing data, The calibration data is transmitted from the transmitter 26 to the thermometer 10 .

The measurement result data generation unit 22 of the smartphone 20 replaces the measurement timing information with time information for all the body temperature data sent from the thermometer 10, and generates measurement result data including the body temperature measurement result numerical value and the measured time. is generated (step S13).

The smartphone 20 calls the smartphone ID, which is its own identification information, from the storage unit 25, collects the measurement result data obtained by converting the body temperature data, the thermometer ID, and the called smartphone ID, and sends the data transmission unit 26 connected to the Internet line. to the cloud server 30 (step S15).

The data receiving unit 37 of the cloud server 30 receives the measurement result data, the thermometer ID, and the smartphone ID transmitted from the smartphone 20 (step S21).

Based on the smartphone ID received together with the measurement result data, the cloud server 30 determination unit 32 calls the thermometer ID associated with the smartphone ID from the storage unit 35 (step S22). Then, the determining unit 32 determines whether or not the thermometer ID associated with the called smartphone ID matches the received thermometer ID (step S23).

If the thermometer ID received by the receiving unit 37 together with the measurement result data matches the thermometer ID called from the storage unit 35 ("Yes" in step S23), the measurement result data is stored in the storage unit along with the thermometer ID. 35 (step S24).

On the other hand, if the thermometer ID received by the receiving unit 37 together with the measurement result data does not match the thermometer ID called from the storage unit 35 (“No” in step S23), the thermometer ID and the smartphone ID are the same. A predetermined flag indicating that they do not match is added (step S25), and the thermometer ID, the measurement result data, and the flag are stored in the storage unit 35 (step S26).

At this time, the caution information generation unit 33 of the cloud server 30 generates caution information warning that the measurement subject is not using the correct thermometer 10, and transmits the caution information to the smartphone 20 possessed by the measurement subject. Upon receiving the caution information, the smartphone 20 displays the content of the caution information on the screen display unit 24 to warn the user to immediately wear the correct thermometer 10 and continue measuring body temperature data. can be emitted to alert the person to be measured.

As described above, in the body temperature measurement system described in this embodiment, the cloud server 30, which is a management device in which biometric information acquired in the system is aggregated, identifies the thermometer 10, which is a measurement terminal that acquires biometric information. From the measurement terminal information, which is information, and the identification information of the smartphone 20, which is the main device that transmits the measurement result of body temperature, which is biological information measured by the measurement terminal, to the cloud server 30, which is the management device. Confirm whether or not the terminal information is associated with the main unit information, and indicate that fact in the data acquired from the measuring terminal that has the measuring terminal information that is not associated with the main unit information. The body temperature measurement result data is recorded with an identification flag indicating . By doing so, when performing various data processing using the biometric information acquired by the cloud server 30, the data to which the identification flag is added can be easily selected. For this reason, for example, biometric information to which an identification flag is added is excluded during data processing in the cloud server 30, and only biometric information obtained from a legitimate measurement subject is used, so that the physical condition of the measurement subject can be managed with high accuracy. can be realized by

In the body temperature measurement system according to the present embodiment, biological information acquired by the thermometer 10 that is not associated with the smartphone 20, which is the main device, is added with a flag indicating that fact. By doing so, in the biological information measuring system according to the present embodiment, even if biological information is not obtained from a legitimate measurement subject, if it can be effectively used as data, data using the obtained data There is an advantage that it can be processed. For example, if it is biological information that shows changes in body temperature over time of a person who is working under almost the same conditions as a regular measurement subject, the biological information obtained from multiple people can be collectively collected as so-called big data. It can be considered that the data can be used when used for analysis of the overall trend or the like. In such a case, when the cloud server 30 collects big data, filtering is performed to remove data that is clearly incorrect as data indicating the result of body temperature measurement, such as measurement errors. It is possible to use biometric information of a different person as valid data.

In addition, the association for setting the correspondence relationship between the thermometer ID (measurement terminal identification information), which is the identification information of the thermometer 10, which is the measurement terminal, and the smartphone ID, which is the main device, may be performed, for example, by the person being measured for the first time. As a procedure for attaching the terminal, there is a method of entering the measurement terminal ID written on the measurement terminal itself into the setting screen of the smartphone that is the main device, and a one-dimensional or two-dimensional identification tag attached to the measurement terminal. The data code is written and the method of reading this data with the camera function of the smartphone that is the main device, and the information that identifies the terminal when pairing Bluetooth, which is a means of short-range communication between the measurement terminal and the main device. Various methods such as reading methods can be used. Also, for example, when distributing a thermometer, which is a measurement terminal, to a person to be measured, the operator of the body temperature management system inputs the measurement terminal information and the main body information separately using a management information processing device such as a personal computer or tablet. is also possible.

Further, after the operation of the thermometer 10 is started, the thermometer ID transmitted together with the first measured body temperature data is recognized as the linked measurement terminal information, and the thermometer different from the first thermometer ID after the start of the measurement of body temperature. When data from a thermometer having an ID is transmitted, it is possible to add an identification flag to the body temperature measurement result received with the different thermometer ID. In this case, the thermometer 10, which is the measurement terminal, and the smartphone 20, which is the main device, do not need to be pre-coupled, and there is an advantage that the biological information measurement system that acquires the biological information of the measurement subject can immediately start operation.

In addition, for example, when the measurement subject has a plurality of smartphones 20, by associating a plurality of main device information with a single measurement terminal information, the smartphone owned by the measurement subject can be used during the measurement period. Even if the smart phone is replaced or if one of the smart phones stops functioning, the biometric information of the person to be measured can be continuously transmitted from the thermometer 10, which is the measurement terminal, to the cloud server 30, which is the management device.

As described above, in the body temperature measurement system described in this embodiment, in addition to the biological information of the subject measured by the thermometer, which is the measurement terminal, and the information identifying the measurement terminal, it is used as a relay device for data transmission. By transmitting the identification information of the main unit to the management device together with the identification information, it detects the situation where the person to be measured is not using the measurement terminal that should be used, and adds an identification flag to the obtained data. In particular, by using a smartphone as the main device, which is used by the measurement subject himself/herself as a means of communication and information gathering, the association between the main device and the measurement subject is ensured, and when the measurement terminal is mistakenly mistaken. Or, if the person to be measured intentionally does not use the measurement terminal that should be used, the biological information obtained in that situation must be reliably selected during data processing and appropriate data processing must be performed. can be done.

In the above-described embodiment, a patch-type thermometer, which is attached to the skin of the person to be measured and fixed with a surgical tape or the like, is exemplified as the measuring terminal. However, the measurement terminal that acquires the biological information of the measurement subject in the biological information measurement system disclosed in the present application is not limited to the patch-type thermometers exemplified above.

For example, a wristwatch type, a clip type that clamps and secures the earlobe or fingertip, and a belt mounting that uses a predetermined fixing belt to fix the measurement terminal to the measurement point such as the wrist, arm, abdomen, or head of the person to be measured. type measuring terminal can be used. In particular, when using a measurement terminal that can be easily attached and detached, such as a wristwatch type or a clip type, or when biometric information is measured intermittently, the measurement subject removes the measurement terminal while taking a bath or sleeps to charge the measurement terminal. In the case of a system in which the measurement terminal is attached incorrectly, it is easy to select the data acquired when the correct measurement terminal is not used. It is more preferable to use the biometric information measurement system disclosed in the present application, which can notify the subject of measurement of a mix-up of .

In addition to the body temperature exemplified in the above embodiment, the biometric information acquired by the measurement terminal can also be various biometric information that can be acquired by the sensor, such as heart rate and amount of perspiration. Furthermore, in addition to pure biological information that represents the biochemical reactions of the human body, information indicating the body movement of the measurement subject acquired by an accelerometer, the location of the measurement subject such as temperature, atmospheric pressure, humidity, and brightness. In the present application, the information output from the sensor capable of measuring the data of the surrounding environment can also be grasped as measurement data conforming to biological information as information for grasping the situation of the person to be measured.

Furthermore, in the above embodiment, a smart phone, particularly a smart phone used by the subject himself/herself, was exemplified as the main device functioning as a relay of biological information acquired by the measurement terminal. As long as it has a transmission/reception function and a function to transmit its own identification information to the management device, the main device is not limited to a smartphone, and is specialized as a tablet terminal or a device dedicated to the biometric information measurement system disclosed in this application. You can use a mobile device with However, if the measurement subject uses a portable device other than a smartphone for personal use as the main device, it is necessary to ensure that the main device is used only by the authorized measurement subject. Become.

In the above embodiment, a cloud server installed on the Internet line is used as a management device. The server is not limited to a cloud server as long as it has a data processing function capable of determining correspondence with identification information and performing data processing using obtained data.

In addition, when the person to be measured is within a limited physical size such as a construction site, sports facility, or event venue, the data transmission from the main unit to the management device uses the Internet environment. is not limited, and a biological information measuring system using a wireless LAN or the like that supports a wide area can be constructed.

In the above embodiment, time management in the thermometer 10, which is a measurement terminal, is performed using timing data indicating measurement intervals. This is because the time information indicating only the measurement interval can be expressed with a smaller number of bits than the case where the UNIX data indicating the actual time is used as the data indicating the measurement time of the biological information. This is because the load on the internal data processing function, storage function, data transmission function, etc. is reduced, and the thermometer 10 can be made smaller and lighter. Therefore, the use of UNIX data as the time information when biometric information is acquired is not excluded.

In addition, data communication between the thermometer, which is the measurement terminal, and the smartphone, which is the main device, is not limited to the above-mentioned Bluetooth standard, but uses wireless communication according to other local rules and electromagnetic induction when placed in close proximity. It is possible to employ various methods that enable short-distance data communication between the terminal device and the main device, such as a data communication method using a terminal device.

A collection of measurement result data acquired by the biological information measurement system disclosed in the present application is accumulated as information indicating changes in the body temperature of the measurement subject, and is appropriately analyzed. used as aggregate data for each temperature data collection purpose.

In addition, using the obtained big data, various feedbacks on the body temperature data of individual measurement subjects, such as the current physical condition evaluation value in the medical field, warning display of the risk of physical condition change, sports related If it is a field, it can be used to display the magnitude of the load of the current practice menu, or to recommend the suspension of practice due to changes in physical condition.

In addition, by using the image display function and data processing function of the smartphone used as the main device, even without using big data, which is a collection of measurement result data obtained from multiple measurement subjects, each Measurement information can be fed back to the measurement subject, such as by displaying the biometric information measurement result of the measurement subject and showing comparison data with the past measurement result of the same measurement subject.

In these cases, environmental data such as temperature data and humidity data that can be acquired by the main device such as a smartphone can be sent to a cloud server on the Internet environment together with the measurement result data, or used as feedback information to the measurement subject. The feedback information can be reflected, appropriately processed based on the environmental information, or added with various variations before notification to the person to be measured.

In the biological information measurement system disclosed in the present application, in addition to the biological information data acquired by the measurement terminal and the identification information of the measurement terminal, when transmitting data to the management device, the identification information of the main device that functions as a repeater , it is possible to detect the situation in which the biometric information of a person other than the legitimate measurement subject is obtained. is given. Therefore, it is useful as a biometric information measurement system that can reliably detect a mix-up of the measuring terminal and can more effectively utilize the acquired biometric information.
