[0030] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to one aspect of the present invention will now be described with reference to the accompanying drawings.

[0031] §1 Application Examples <Information management system 100 to which the present invention is applied> FIG. 1 is a diagram showing an example of an information management system 100 including a measuring device 1 of the present invention and an information terminal 5 that communicates wirelessly with the measuring device 1.

[0032] The measuring device 1 includes, for example, a weighing scale, a blood pressure monitor, a body composition monitor, and the like, capable of measuring biological information. The measuring device 1 is a measuring device that is used while placed on the ground or a stand. The measuring device 1 may also include an activity measuring device that measures activity amounts such as the number of steps, walking distance, or calories burned. The activity measuring device is a wearable measuring device that is carried by being attached to the user's body. In contrast to wearable measuring devices, non-wearable measuring devices (such as weighing scales and blood pressure monitors) are called non-wearable measuring devices. The measuring device 1 transmits the measured biological information, activity amounts, and the like to the information terminal 5 via wireless communication as user management measurement information. Note that FIG. 1 shows a blood pressure monitor capable of measuring blood pressure as the measuring device 1. However, the blood pressure monitor cuff and other components are not shown.

[0033] The information terminal 5 stores the management measurement information received from the measurement device 1 in a data storage unit within the information terminal 5. The information terminal 5 is also capable of wireless communication with devices other than the measurement device 1, and stores information acquired from external devices in a data storage unit within the information terminal 5. The information terminal 5 is an information processing device that analyzes various information acquired from the measurement device 1 and other external devices. The information terminal 5 is, for example, a terminal with a display, such as a smartphone, tablet terminal, laptop computer, desktop computer, or wearable terminal. The information terminal 5 may be configured to acquire management measurement information from a specific measurement device 1. The specific measurement device 1 from which the management measurement information is to be acquired may be registered in advance in the data storage unit of the information terminal 5.

[0034] Fig. 2 is a diagram showing an example in which an information terminal 5 is connected to a network. As shown in Fig. 2, the information terminal 5 may be connected to a cloud server 90 via a wide area network N such as the Internet. The information terminal 5 may transmit the management measurement information stored therein to the cloud server 90 via the wide area network N, and the cloud server 90 may manage the user's management measurement information as a database. The information terminal 5 may also acquire the management measurement information managed in the cloud server 90 via the wide area network N, and use the acquired management measurement information.

[0035] §2 Configuration example <Configuration of Measuring Device 1> 3 is a block diagram showing the configuration of the measuring device 1. The measuring device 1 includes a display unit 11 that displays various information, an operation unit 12 operated by the user, a measuring unit 13 that measures biological information, activity levels, etc., a wireless communication unit 14 capable of wireless communication with external devices, a timing unit 15 that generates time information, and a sensor 16 that can detect whether the measuring device 1 is stationary or tilted. The measuring device 1 also includes a RAM 17 that temporarily stores information, a data storage unit 18 that stores information and programs, and a controller 19 that controls the overall operation. The measuring device 1 also includes a battery box 20 for mounting a battery, an external power supply connection unit 21 for connecting an external power supply, and a power management unit 22 that manages the power status of the battery box 20 and the external power supply connection unit 21.

[0036] Display unit 11 is configured with, for example, a liquid crystal display or an organic EL (Electro Luminescence) display. Operation unit 12 is a user interface that accepts user operations, such as buttons or a touch panel. Buttons include buttons that are physically provided on measurement device 1 and virtual buttons displayed on display unit 11.

[0037] The measurement unit 13 measures biological information such as weight, blood pressure, and body composition, or activity levels such as the number of steps, walking distance, and calories burned. What is measured varies depending on the object being measured by the measurement device 1.

[0038] The wireless communication unit 14 is a communication unit that performs short-range wireless communication, for example, a circuit (module) for performing communication according to the BLE (Bluetooth Low Energy (registered trademark)) standard. The wireless communication unit 14 transmits an advertising signal for performing wireless communication to an unspecified number of external devices via broadcast communication at a predetermined transmission cycle. The wireless communication unit 14 transmits the advertising signal including, for example, the name and attribute information of the measurement device 1, or information about the model. The BLE communication performed by the wireless communication unit 14 is communication that uses, for example, a 2.4 GHz frequency. The wireless communication unit 14 transmits management measurement information, such as biological information or activity levels measured by the measurement unit 13, to, for example, the information terminal 5 via BLE communication.

[0039] The timekeeping unit 15 generates time information to be displayed on the display unit 11 of the measuring device 1, for example. "Time information" includes the current time, such as the current date, day of the week, and time. The timekeeping unit 15 can operate using both a battery and an external power source. The external power source is, for example, an AC (Alternating Current) power source. "Operable using both a battery and an external power source" means that the timekeeping unit 15 can operate with either an external power source or a battery (with remaining power). When both the mains power source and an external power source are present, the timekeeping unit 15 operates using at least one of the external power source and the battery (with remaining power) as its power source (for example, it operates using the external power source). When both the mains power source and an external power source are present, the timekeeping unit 15 may operate using at least one of the external power source and the battery (with remaining power) as its power source while charging the battery (assuming it is a secondary battery) using the external power source. Note that not only the timekeeping unit 15 but the entire measuring device 1 may also be able to operate using both a battery and an external power source. The timekeeping unit 15 becomes unable to keep time when there is no power supply from the battery or the external power source. "Becoming unable to keep time" means that the correct current date and time information cannot be obtained.

[0040] The sensor 16 is, for example, an acceleration sensor or an inclination sensor. The sensor 16 detects when the measuring device 1 (the device itself) comes to a standstill due to the cessation of activity when a user wearing the measuring device 1 stops the activity. The sensor 16 also detects when the measuring device 1 comes to a standstill due to the user removing the measuring device 1 from the user's body and placing it on a desk or the like. The sensor 16 also detects when the measuring device 1 is placed on the ground or a stand, or when it is tilted and held up.

[0041] The RAM 17 is configured by a semiconductor device such as a DRAM or an SRAM, and serves as a working area for the controller 19 as well as temporarily storing information.

[0042] The data storage unit 18 is a recording medium that stores parameters, control programs, management measurement information, etc., required to realize predetermined processing. The data storage unit 18 is configured, for example, by a hard disk drive (HDD) or a semiconductor storage device (SSD).

[0043] Controller 19 performs predetermined processing by executing a control program. In this embodiment, for example, health management application software for the measuring device is pre-installed as a control program in data storage unit 18, and controller 19 performs predetermined processing by executing this health management application software.

[0044] For example, the controller 19 associates the biological information measured by the measurement unit 13 (an example of management measurement information) with the time information generated by the timer unit 15 and transmits the associated information to the information terminal 5 via the wireless communication unit 14. The controller 19 also determines whether or not there is battery power supply, and transmits power supply information indicating the determination result to the information terminal 5 via the wireless communication unit 14. "Whether or not there is battery power supply" refers to whether or not a battery with sufficient remaining charge to operate is attached to the measurement device 1. For example, if there is no battery, or if there is a battery but no remaining charge, the battery power supply is determined to be "not present." The presence or absence of battery power supply is determined based on the voltage measurement results of the power supply line from the battery. The controller 19 also determines whether or not there is power supply from an external power source, and transmits power supply information indicating the determination result to the information terminal 5 via the wireless communication unit 14. The presence or absence of power supply from an external power source is determined based on the voltage measurement results of the power supply line from the external power source.

[0045] Furthermore, the controller 19 transmits the power supply information to the information terminal 5 when a wireless connection with the information terminal 5 is established by the wireless communication unit 14. That is, the controller 19 transmits the power supply information to the communication partner when a one-to-one wireless connection is established, rather than sending (repeatedly scattering) the information as a broadcast signal like an advertisement signal.

[0046] The battery box 20 is a box into which a battery can be attached or detached. The battery box 20 is electrically connected to a power supply management unit 22. The external power supply connection unit 21 is a portion to which, for example, an AC adapter is connected. The AC adapter may be detachably attached to the external power supply connection unit 21. The external power supply connection unit 21 is electrically connected to the power supply management unit 22. The power supply management unit 22 supplies operating voltage to each unit. The power supply management unit 22 may be configured to determine whether a battery is attached to the battery box 20 by measuring the voltage of a power supply line from the battery. For example, the power supply management unit 22 measures the voltage of the power supply line from the external power source to determine whether, for example, an AC adapter is connected to the external power supply connection unit 21 and external power is being supplied, and outputs the determination result to the controller 19. However, the power supply management unit 22 may be configured not to determine whether a battery is attached to the battery box 20.

[0047] <Configuration of information terminal 5> 4 is a block diagram showing the configuration of the information terminal 5. The information terminal 5 includes a display unit 51 that displays various information, an operation unit 52 that the user operates, a first wireless communication unit 53 and a second wireless communication unit 54 that can communicate wirelessly with external devices. The information terminal 5 also includes a RAM 55 that temporarily stores information, a data storage unit 56 that stores information and programs, and a controller 57 that controls the overall operation. The controller 57 is an example of the "processor" of the present invention.

[0048] The display unit 51 is configured with, for example, a liquid crystal display or an organic EL display. The operation unit 52 is a user interface that accepts user operations such as buttons or a touch panel. The buttons include buttons that are physically provided on the information terminal 5 and virtual buttons displayed on the display unit 51.

[0049] The first wireless communication unit 53 is a communication unit that performs cellular communication, such as a circuit (module) for communication in accordance with standards such as 4G, 5G, and LTE (Long Term Evolution: registered trademark). The first wireless communication unit 53 is also a communication unit that performs wireless LAN communication, such as a circuit (module) for communication in accordance with standards such as Wi-Fi (registered trademark). The second wireless communication unit 54 is a communication unit that performs short-range wireless communication, such as a circuit (module) for communication in accordance with the BLE standard.

[0050] The second wireless communication unit 54 acquires management measurement information of the user measured by the measurement device 1, for example, by performing BLE communication with the wireless communication unit 14 of the measurement device 1. The second wireless communication unit 54 receives an advertising signal transmitted from the wireless communication unit 14 of the measurement device 1 by scanning. The second wireless communication unit 54 recognizes the measurement device 1 from the received advertising signal, and transmits a connection request to the measurement device 1 when it desires to establish a communication connection. After transmitting the advertising signal, the measurement device 1 waits for a connection request for a predetermined time, and upon receiving a connection request within the predetermined time, stops transmitting the advertising signal and switches to one-to-one connection communication with the other party of the connection request.

[0051] The RAM 55 is configured by a semiconductor device such as a DRAM or an SRAM, and temporarily stores information and also serves as a working area for the controller 57 .

[0052] The data storage unit 56 is a recording medium that stores parameters necessary to realize predetermined processing, control programs, and management measurement information acquired from the measurement device 1. The data storage unit 56 also stores images of, for example, each model of the measurement device 1 that can be connected to the information terminal 5 via wireless communication, along with their names, attributes, model numbers, etc. The data storage unit 56 is configured, for example, by a hard disk drive (HDD) or a semiconductor storage device (SSD).

[0053] Controller 57 performs predetermined processing by executing a control program. In this embodiment, for example, health management application software for an information terminal is pre-installed as a control program in data storage unit 56, and controller 57 performs predetermined processing by executing this health management application software. For example, when the health management application software for the information terminal is launched, controller 57 controls second wireless communication unit 54 to scan and receive an advertising signal. When controller 57 receives an advertising signal from measurement device 1, controller 57 controls second wireless communication unit 54 to send a connection request to measurement device 1 and acquire management measurement information from measurement device 1.

[0054] Furthermore, if valid time information is not associated with the biometric information received from the measuring device 1 by the second wireless communication unit 54, the controller 57 notifies the user of the reason why valid time information is not associated with the biometric information. "Valid time information is not associated" means, for example, that time information has not been added. "Valid time information is not associated" may also mean that a false time (such as 99:99) that is clearly invalid has been added. The "reason" relates to the state of the power supply of the measuring device 1 (presence or absence of a battery, presence or absence of an AC power source). The "notification" is a notification by the information terminal 5, for example, a notification displayed on a screen or output as audio.

[0055] An example of the message may simply read, "There may be no batteries in the device." The notification may also include a notification urging the user to insert batteries even when using an external power source. An example of the message may read, "To correctly record the measurement time, please insert batteries into the measurement device, even when using an AC adapter." Or, "There may be no batteries in the device. To correctly record the measurement time, please insert batteries, even when using an AC adapter." Another example of the message may read, "If there are no batteries in the device, to correctly record the measurement time, please insert batteries into the measurement device, even when using an AC adapter. If you replaced the battery in the measurement device without using an AC adapter, please communicate with the health management application after the battery replacement and set the time before performing a measurement. If there are batteries in the measurement device but you have not replaced the batteries, please contact user support."

[0056] The controller 57 also receives power supply information indicating whether or not the measuring device 1 is receiving power from a battery via the second wireless communication unit 54 from the measuring device 1, and notifies the user based on the received power supply information. The "power supply information" is information that causes the information terminal 5 to notify the user. The "power supply information" may be received together with the biometric information, or may be received by requesting the measuring device 1 when biometric information that is not associated with valid time information is received.

[0057] The "power supply information" may be information indicating whether the measuring device 1 is being powered by a battery or an external power source. If, based on the received power supply information, the measuring device 1 is not being powered by a battery but is being powered by an external power source, the controller 57 notifies the user to insert a battery even when using an external power source. An example of such a message is, "In order to correctly record the measurement time, please insert a battery even when using an AC adapter."

[0058] Furthermore, if, based on the received power supply information, the controller 57 determines that the measuring device 1 is being powered by a battery but not by an external power source, it notifies the user to set the time on the measuring device 1 after replacing the battery before measuring biological information. An example of such a message is, "After replacing the battery, please communicate with the health management application to set the time before performing a measurement." However, time setting is not limited to being set by communication with the health management application, and may also be performed by the user operating a time setting button on the measuring device 1, for example.

[0059] The determination of "presence or absence of power supply from a battery" and "presence or absence of power supply from an external power source" is made, for example, when measuring biological information in the measurement device 1. However, the determination of these presence or absence may be made immediately before transmitting the biological information, may be made when starting up the measurement device 1, or may be made periodically while the measurement device 1 is running.

[0060] §3 Example of operation <First Operation Example of Information Management System 100> 5 is a sequence diagram showing a first operation example of the information management system 100. Assume that a user carrying an information terminal 5 (e.g., a smartphone) is about to measure the user's blood pressure using the measurement device 1 (e.g., a sphygmomanometer). The first operation example is an operation performed when a battery is installed in the measurement device 1 and a valid time is set in the measurement device 1.

[0061] First, the user connects the measurement device 1 to an AC power source (step S11) and turns on the power to the measurement device 1. As described above, the measurement device 1 is in a "battery-equipped" state, and the time is set to valid. In the following explanation, this state is referred to as the valid time period VP (the period indicated by the hatched area).

[0062] The measurement device 1 measures blood pressure based on the user's measurement operation (step S12). The measurement device 1 stores the measured blood pressure measurement data in the data storage unit 18 (step S13). The measurement data stored at this time is data (measurement data (with time)) stored in association with time information held by the measurement device 1.

[0063] The health management application on the information terminal 5 is started by the user.

[0064] The information terminal 5 accepts a connection operation by starting the health management application (step S14). Specifically, the information terminal 5 scans to detect an advertising signal from the measurement device 1, and transmits a connection request signal to the measurement device 1 based on the detected advertising signal. In response, the measurement device 1 receives the connection request and switches to one-to-one connection communication with the information terminal 5. This establishes a wireless connection between the information terminal 5 and the measurement device 1 (step S15). The information terminal 5 transmits time information held by the information terminal 5 to the measurement device 1 (step S16). The time information of the information terminal 5 is accurate time information because it is set based on information from the Internet.

[0065] The measurement device 1 sets the time of the time information held by the measurement device 1 based on the time information received from the information terminal 5 (step S17). This time setting corrects the discrepancy between the time information held by the measurement device 1 and the time information received from the information terminal 5 in step S16. The measurement device 1 transmits the measurement data (with time) saved in step S13 to the information terminal 5 (step S18).

[0066] The information terminal 5 stores the measurement data (with time stamp) received from the measurement device 1 in the data storage unit 56 (step S19).

[0067] The user turns off the power to the measurement device 1 and unplugs the AC adapter from the outlet (step S20). Even if the AC adapter is unplugged, the time information of the measurement device 1 is still valid because the battery is still installed.

[0068] If a battery is installed in the measuring device 1, the above-described usage is repeated. The timing for setting the time on the measuring device 1 (steps S16 and S17) may be, but is not limited to, when wireless connection is established (step S15). For example, the timing for setting the time may be after the measurement data is transferred (step S18). After the measurement data has been transmitted to the information terminal 5, the measuring device 1 may delete the measurement data stored in the measuring device 1.

[0069] <Second Operation Example of Information Management System 100> 6 is a sequence diagram showing a second operation example of the information management system 100. The second operation example is an operation for notifying the user of the reason why the time information is invalid when there is no battery in the measuring device 1 and a valid time is not set in the measuring device 1.

[0070] First, the user connects the measurement device 1 to an AC power source (step S11) and turns on the power to the measurement device 1. As described above, the measurement device 1 is in a "battery-free" state. Therefore, if the measurement device 1 is connected to an AC power source without a battery, the time on the measurement device 1 will not be valid unless it is reset.

[0071] The measurement device 1 measures blood pressure based on the user's measurement operation (step S12). The measurement device 1 stores the measured blood pressure measurement data in the data storage unit 18 (step S13). The measurement data stored at this time is "time-unknown" data that is not associated with valid time information.

[0072] Next, the user launches a health management application on the information terminal 5, and the information terminal 5 accepts a connection operation resulting from the launch of the health management application (step S14). The specific connection process is the same as the process described in the first operation example of FIG. 5. This establishes a wireless connection between the information terminal 5 and the measurement device 1 (step S15). The information terminal 5 transmits time information held by the information terminal 5 to the measurement device 1 (step S16). The time information on the information terminal 5 is accurate time information based on information from the Internet.

[0073] The measurement device 1 sets the time for the time information stored in the measurement device 1 based on the time information received from the information terminal 5 (step S17). This time setting places the measurement device 1 in a time valid period VP (period of the hatched area) during which the time is set valid. The measurement device 1 transmits the measurement data (without time) saved in step S13 to the information terminal 5 (step S18).

[0074] The information terminal 5 stores the measurement data (without time) received from the measurement device 1 in the data storage unit 56 (step S19).

[0075] The user turns off the power to the measurement device 1 and unplugs the AC adapter from the outlet (step S20). When the AC adapter is unplugged, the time information of the measurement device 1 that was set in step S17 becomes invalid (the set time is lost).

[0076] Based on the measurement data (without time) received from the measurement device 1, the information terminal 5 displays a notification screen on the display unit 51 to notify the user that there is a possibility that the battery is not installed in the measurement device 1 (step S21).

[0077] If no battery is installed in the measuring device 1, the above-described usage is repeated. Note that in the above example, the measuring device 1 transmits measurement data without a time stamp (no time) to the information terminal 5 (step S18), but this is not limited to this. For example, the measuring device 1 may transmit to the information terminal 5 a false time (e.g., 99:99) that can be determined to indicate that the time information added to the measurement data is invalid.

[0078] <Example of notification screen displayed on information terminal 5> Fig. 7 is a diagram showing a first notification screen 61 displayed on the information terminal 5 in the second operation example of Fig. 6. The first notification screen 61 is a screen that notifies the user that a battery may not be installed in the measurement device 1. The first notification screen 61 is displayed on the display unit 51, for example, in step S21 of Fig. 6.

[0079] 7, a message 62 such as "There may be no battery in the main unit" is displayed on the first notification screen 61. Also, a device image 63 showing the target measurement device (for example, a blood pressure monitor) is displayed on the first notification screen 61.

[0080] Fig. 8 is a diagram showing a second notification screen 64 displayed on information terminal 5 in the second operation example of Fig. 6. Second notification screen 64 is a screen that prompts the user to insert a battery into measuring device 1 even when an external power source is used for measuring device 1. Second notification screen 64 is displayed on display unit 51, for example, in step S21 of Fig. 6.

[0081] 8, the second notification screen 64 displays a message 65 such as, "There may be no battery in the main unit. To correctly record the measurement time, please turn on the power even when using AC power." Also, the second notification screen 64 displays a device image 63 showing the target measurement device (for example, a blood pressure monitor).

[0082] Fig. 9 is a diagram showing a third notification screen 66 displayed on the information terminal 5 in the second operation example of Fig. 6. The third notification screen 66 is a screen that prompts the user to set the time on the measurement device 1 after replacing the battery and before measuring biological information. The third notification screen 66 is displayed on the display unit 51, for example, in step S21 of Fig. 6.

[0083] 9, the third notification screen 66 displays a message 67 such as, "If there is no battery in the main unit, please insert a battery even when using AC power to correctly record the measurement time. If you have replaced the battery in the main unit without using AC power, please communicate with the app after the battery replacement and set the time before measurement. If there is a battery in the main unit but you have not replaced the battery, please contact user support." Also, the third notification screen 66 displays a device image 63 indicating the target measurement device (for example, a blood pressure monitor).

[0084] As described above, when valid time information is not associated with the measurement data of the biological information received from the measuring device 1, the information terminal 5 notifies the user of the reason why valid time information is not associated with the measurement data of the biological information. With this configuration, for example, by notifying the user that valid time information may not be associated because there is no battery in the measuring device 1, the user can be prompted to take appropriate action, such as inserting a battery into the measuring device 1 to obtain valid time information. Furthermore, by notifying the user that valid time information may not be associated because, for example, the battery in the measuring device 1 was replaced but the time was not set before measuring blood pressure, the user can be prompted to take appropriate action, such as communicating with the app and setting the time before the next measurement. Furthermore, for example, when a battery is installed in the measuring device 1 but has not been replaced, the user can be prompted to take appropriate action, such as contacting user support, by notifying the user that valid time information may not be associated because there is a malfunction in the measuring device 1.

[0085] <Third Operation Example of Information Management System 100> 10 is a sequence diagram showing a third operation example of the information management system 100. The third operation example is an operation in which, when the measuring device 1 is used only with an AC power source and a valid time is not set in the measuring device 1, the user is notified of the reason why the time information is invalid based on power supply information indicating whether or not power is being supplied.

[0086] First, the user connects the measurement device 1 to an AC power source (step S11) and turns on the power to the measurement device 1. As described above, the measurement device 1 is in a "battery-free" state. Therefore, when the measurement device 1 is connected to an AC power source without a battery, the time on the measurement device 1 will not be valid unless it is set.

[0087] The measurement device 1 measures blood pressure based on the user's measurement operation (step S12). Next, the measurement device 1 performs a battery determination to determine whether a battery is installed in the measurement device 1 and an AC power determination to determine whether an AC power source is connected to the measurement device 1 (step S13A). The measurement device 1 determines whether a battery is installed by measuring the voltage of the power supply line from the battery. The measurement device 1 also determines whether an AC power source is installed by measuring the voltage of the power supply line from an external power source. In this example, the result of the battery determination is "battery not installed," and the result of the AC power determination is "AC power installed." The measurement device 1 saves the measured blood pressure measurement data and power source information indicating whether power is supplied by a battery or an AC power source in the data storage unit 18 (step S13B). The measurement data saved at this time is "no time" data that is not associated with valid time information. The power source information saved is "battery not installed," which indicates no power is supplied by a battery, and "AC power installed," which indicates power is supplied by an AC power source.

[0088] The health management application on the information terminal 5 is started by the user.

[0089] The information terminal 5 accepts a connection operation by starting up a health management application (step S14). The specific connection process is the same as the process described in the first operation example of FIG. 5. This establishes a wireless connection between the information terminal 5 and the measurement device 1 (step S15). The information terminal 5 transmits time information held by the information terminal 5 to the measurement device 1 (step S16). The time information of the information terminal 5 is accurate time information based on information from the Internet.

[0090] The measurement device 1 sets the time information stored in the measurement device 1 based on the time information received from the information terminal 5 (step S17). This time setting places the measurement device 1 in a time valid period VP (the period indicated by the hatched area) during which the time is set valid. The measurement device 1 transmits the measurement data (without time) and power information saved in step S13B to the information terminal 5 (step S18).

[0091] The information terminal 5 stores the measurement data (without time) received from the measurement device 1 in the data storage unit 56 (step S19).

[0092] The user turns off the power to the measurement device 1 and unplugs the AC adapter from the outlet (step S20). When the AC adapter is unplugged, the time information of the measurement device 1 that was set in step S17 is no longer valid.

[0093] Based on the fact that the measurement data does not have a time stamp and the power supply information is "no battery," the information terminal 5 displays a notification screen on the display unit 51 informing the user that there is no battery in the measuring device 1 (step S21).

[0094] The third operation example described above is a situation in which it can be assumed that there is no valid time information because the measuring device 1 is being used only with AC power. Therefore, an example of a message displayed on the notification screen would be, "There are no batteries in the main unit. To correctly record the measurement time, please insert batteries even when using an AC adapter."

[0095] Note that since "battery determination" and "AC power determination" are performed in step S13A, the power information is "whether or not there is battery power supply" and "whether or not there is AC power supply," but this is not limited to this. For example, only "battery determination" may be performed in step S13, and the power information may be "whether or not there is battery power supply." Even if "AC power determination" is not performed in this way, when it is determined that there is no battery power supply, this determination is made based on the operation of the measuring device 1 using an external power source, and the measuring device 1 cannot operate without power supply from an external power source. Therefore, it can be determined that there is power supply from an external power source.

[0096] When using the measuring device 1 only on AC power and notifying the user based on power supply information, the above-mentioned usage is repeated. Note that the above example describes the case where the measuring device 1 does not have a battery, but this is not limited to this. For example, if the measuring device 1 has a battery (for example, the first operation example in Figure 5), the battery determination and AC power determination may be performed in the same way and the power supply information may be transmitted. However, in this case, the information terminal 5 receives measurement data with the time stamp, so an example message on the notification screen may be, for example, "A battery is installed in the main unit. To correctly record the measurement time, please do not remove the battery even when using an AC adapter."

[0097] Furthermore, in the above example, power supply information is transmitted simultaneously with the measurement data, but this is not a limitation. For example, if the measurement device 1 transmits only measurement data and the information terminal 5 receives measurement data without a time stamp, the power supply information may be requested from the measurement device 1. Furthermore, in the above example, the battery determination and AC power determination are performed immediately after measuring the biological information (step S12), but this is not a limitation. For example, the battery determination and AC power determination may be performed immediately before transmitting the measurement data to the information terminal 5, when the measurement device 1 is started up, or periodically while the measurement device 1 is running.

[0098] In this way, the information terminal 5 in the third operation example notifies the user to insert a battery even when using an external power source when the measuring device 1 is not receiving power from a battery but is receiving power from an external power source, based on the power source information received from the measuring device 1. With this configuration, when the measuring device 1 is being used solely on AC power without a battery, the user can be prompted to take the appropriate action of inserting a battery into the measuring device 1 based on the notification from the information terminal 5 in order to obtain valid time information.

[0099] <Fourth Operation Example of Information Management System 100> 11 is a sequence diagram showing a fourth operation example of the information management system 100. The fourth operation example is an operation when the measuring device 1 is used solely on a battery, and when the battery is replaced, the user is notified of the reason why the time information is invalid based on power supply information indicating whether or not power is being supplied.

[0100] The measurement device 1 is in a "battery present" state with a battery installed, and is in a time valid period VP (period indicated by the hatched area) in which the time is set valid. Now, suppose the user replaces the battery in the measurement device 1 (step S31) and then turns on the power to the measurement device 1. When the battery is replaced, the time information that was valid up until that point is lost, and the time will no longer be set valid unless it is reset.

[0101] The measurement device 1 measures blood pressure based on the user's measurement operation (step S12). Next, the measurement device 1 performs a battery determination to determine whether a battery is installed in the measurement device 1, and an AC power determination to determine whether an AC power source is connected to the measurement device 1 (step S13A). The measurement device 1 determines whether a battery is installed by measuring the voltage of the power supply line from the battery, and determines whether an AC power source is installed by measuring the voltage of the power supply line from the external power source. In this example, the result of the battery determination is "battery present," and the result of the AC power determination is "no AC power." The measurement device 1 saves the measured blood pressure measurement data and power source information indicating whether power is supplied by a battery or an AC power source in the data storage unit 18 (step S13B). The measurement data saved at this time is "no time" data that is not associated with valid time information. The power source information saved is "battery present," which indicates whether power is supplied by a battery, and "no AC power," which indicates no power is supplied by an AC power source.

[0102] Next, the user launches a health management application on the information terminal 5, and the information terminal 5 accepts a connection operation resulting from the launch of the health management application (step S14). The specific connection process is the same as the process described in the first operation example of FIG. 5. This establishes a wireless connection between the information terminal 5 and the measurement device 1 (step S15). The information terminal 5 transmits time information held by the information terminal 5 to the measurement device 1 (step S16). The time information on the information terminal 5 is accurate time information based on information from the Internet.

[0103] The measurement device 1 sets the time information stored in the measurement device 1 based on the time information received from the information terminal 5 (step S17). This time setting places the measurement device 1 in a time valid period VP (the period indicated by the hatched area) during which the time is set valid. The measurement device 1 transmits the measurement data (without time) and power information saved in step S13B to the information terminal 5 (step S18).

[0104] The information terminal 5 stores the measurement data (without time) received from the measurement device 1 in the data storage unit 56 (step S19). Based on the fact that no time has been added to the measurement data and that the power supply information indicates "battery present," the information terminal 5 displays a notification screen on the display unit 51 urging the user to set the time on the measurement device 1 before measuring blood pressure after replacing the battery (step S20).

[0105] The fourth operation example described above is a situation in which it can be assumed that valid time information is no longer associated with the measuring device 1 because the measuring device 1 is being used solely on battery power and the battery has been replaced. If the measuring device 1 is being used solely on battery power and the battery has been replaced, the above-described usage cycle will be repeated.

[0106] As in step S13B described above, the power information indicates not only whether or not power is supplied by a battery, but also whether or not power is supplied by an external power source. This makes it possible to distinguish between cases where the device is being used solely on battery power ("no external power source + battery present") and cases where the device is being used on both battery power and an external power source ("external power source + battery present"). Incidentally, when the device is being used on both battery power and an external power source ("external power source + battery present") and time information is not added to the measurement data, this indicates a high possibility of a malfunction of the measuring device 1. An example of a message in this case would be, "If a battery is installed in the device and has not been replaced, please contact user support. (However, this does not apply if other causes can be suspected.)"

[0107] <Example of notification screen displayed on information terminal 5> Fig. 12 is a diagram showing a fourth notification screen 68 displayed on the information terminal 5 in the fourth operation example of Fig. 11. The fourth notification screen 68 is a screen that prompts the user to set the time on the measurement device 1 after replacing the battery. The fourth notification screen 68 is displayed on the display unit 51, for example, in step S20 of Fig. 11.

[0108] 12, a message 69 such as "After replacing the battery, please communicate with the app and set the time before measurement" is displayed on the fourth notification screen 68. Also, a device image 63 showing the target measurement device (for example, a blood pressure monitor) is displayed on the fourth notification screen 68.

[0109] In this way, the information terminal 5 in the fourth operation example notifies the user that, if the measuring device 1 is being powered by a battery but not by an external power source, the measuring device 1 is being powered based on the power information received from the measuring device 1, to set the time on the measuring device 1 after replacing the battery before measuring the biological information. With this configuration, in order to obtain valid time information when the measuring device has been used solely on battery power but the battery has been replaced, the user can be prompted, based on the notification from the information terminal 5, to take the appropriate action of setting the time after replacing the battery and then measuring the biological information.
