[0003] [Patent Document 1] Japanese Patent Publication No. 2022-164560 Summary of the Invention [Problem to be solved by the invention]

[0004] Subjects whose biometric information is to be acquired engage in various activities in their daily lives. The risk of abnormalities occurring in the subject's biometric information varies depending on the type of activity. Nevertheless, if the same biometric information is always acquired regardless of the subject's activity, the acquired biometric information may be excessive or insufficient. The information processing system described in Patent Document 1 does not take this into consideration at all, and therefore there is room for improvement. [Means for solving the problem]

[0005] In order to solve the above problems, the present invention is a health management system that executes an acquisition process for acquiring a subject's biometric information over time, a bathing judgment process for detecting the start and end of bathing of the subject, and a judgment process for judging abnormalities in the subject based on the progress of the biometric information, wherein the acquisition process acquires the biometric information in a first measurement mode during the pre-bathing period before the start of bathing is determined in the bathing judgment process, and acquires the biometric information in a second measurement mode during the bathing period from the start of bathing is determined in the bathing judgment process to the end of bathing, and the first measurement mode and the second measurement mode differ in at least one selected from the measurement frequency of the biometric information and the type of biometric information acquired. [Effects of the Invention]

[0006] According to the above configuration, it is possible to prevent excess or deficiency of acquired biometric information. [Brief explanation of the drawings]

[0007] [Figure 1] Figure 1 shows the overall configuration of the health management system. [Figure 2] FIG. 2 is a sequence diagram showing the processing of the health management system. DETAILED DESCRIPTION OF THE INVENTION

[0008] An embodiment of a health management system will be described below with reference to the drawings. <Overall structure> As shown in FIG. 1, the health management system 10 includes a biosensor 20, a plurality of bathing detection sensors 30, a mobile terminal 40, a server 50, and an external terminal 60.

[0009] The biosensor 20 includes functions as a pulse oximeter, a temperature sensor, and an acceleration sensor. The biosensor 20 is a wearable terminal that can be attached to the fingertip or wrist of the subject. The biosensor 20 acquires four types of bioinformation BI.

[0010] The biosensor 20 functions as a pulse oximeter, thereby measuring the subject's blood oxygen saturation and pulse rate as bioinformation BI. Preferably, the biosensor 20 calculates the blood oxygen saturation and pulse rate from the transmittance of red light and infrared light when the subject is irradiated with the light. The biosensor 20 functions as a temperature sensor, thereby measuring the subject's body temperature as bioinformation BI. The biosensor 20 functions as an acceleration sensor, thereby measuring the subject's acceleration as bioinformation BI. The subject's acceleration can be used to detect the subject's movements, such as the subject's number of steps.

[0011] Although not shown, the biosensor 20 includes a memory unit and a communication unit. The memory unit and communication unit may be configured as a single chip or module, or may be configured as separate chips or modules. The memory unit may include a read-only ROM, a readable / writable non-volatile memory, a readable / writable volatile memory, etc. This also applies hereinafter.

[0012] The storage unit stores the detected biometric information BI. The communication unit is capable of communicating with an external device. The communication method of the communication unit is, for example, Bluetooth (registered trademark). The biometric sensor 20 is capable of transmitting the biometric information BI stored in the storage unit to the external device via the communication unit.

[0013] The biosensor 20 is capable of executing an acquisition process. The acquisition process is a process of acquiring bioinformation BI over time. As described above, the biosensor 20 is capable of measuring the subject's blood oxygen saturation, pulse rate, body temperature, and acceleration as the bioinformation BI. The biosensor 20 stores the measured bioinformation BI in a memory unit. Then, the biosensor 20 transmits the bioinformation BI to the mobile terminal 40 every time it measures the bioinformation BI.

[0014] The bathing detection sensor 30 includes a human presence sensor 31 and a flow rate sensor 32. The human presence sensor 31 is installed in the bathroom. The human presence sensor 31 is capable of detecting the presence or absence of a person in the bathroom. In other words, the human presence sensor 31 is capable of sensing a subject in the bathroom. The human presence sensor 31 is, for example, a pyroelectric infrared sensor that detects temperature changes of a heat source within a detection area. The human presence sensor 31 may also be incorporated into a light bulb or the like in the bathroom. Although not shown in the figures, the human presence sensor 31 includes a communication unit. The communication unit is capable of communicating with external devices. The communication unit uses, for example, Bluetooth (registered trademark).

[0015] If the human presence sensor 31 detects that there is a person in the bathroom, it transmits a detection signal to the mobile terminal 40. If the human presence sensor 31 does not detect a person in the bathroom, it transmits a non-detection signal to the mobile terminal 40. The human presence sensor 31 can transmit the detection signal and non-detection signal to the mobile terminal 40 via the communication unit.

[0016] The flow sensor 32 is attached to the shower in the bathroom. The flow sensor 32 can detect the presence or absence of a person in the bathroom based on detecting a flow rate equal to or greater than a predetermined specified amount. The specified amount is determined based on the flow rate of the shower during bathing confirmed through experiments, etc. Although not shown in the figure, the human presence sensor 31 is equipped with a communication unit. The communication unit is capable of communicating with external devices. The communication method of the communication unit is, for example, Bluetooth (registered trademark).

[0017] If the flow sensor 32 detects that a person is in the bathroom, it transmits a detection signal to the mobile terminal 40. If the flow sensor 32 does not detect a person in the bathroom, it transmits a non-detection signal to the mobile terminal 40. The flow sensor 32 can transmit the detection signal and non-detection signal to the mobile terminal 40 via the communication unit.

[0018] In this embodiment, the mobile terminal 40 is a smartphone owned by the subject. Although not shown in the drawings, the mobile terminal 40 includes a storage unit, a first communication unit, and a second communication unit. In this embodiment, the communication method of the first communication unit is Bluetooth (registered trademark). The communication method of the second communication unit is a method using a mobile phone communication network. Therefore, the communication range of the second communication unit of the mobile terminal 40 is wider than the communication range of the first communication unit.

[0019] The mobile terminal 40 can acquire the biometric information BI from the biometric sensor 20 via the first communication unit. The mobile terminal 40 can also acquire the detection signal and non-detection signal from the bathing detection sensor 30 via the first communication unit. The mobile terminal 40 can also store the biometric information BI, detection signal, and non-detection signal in a memory unit. The mobile terminal 40 can transmit the biometric information BI, detection signal, and non-detection signal stored in the memory unit of the mobile terminal 40 to the server 50 via the second communication unit.

[0020] Although not shown, the server 50 has a control unit, a storage unit, and a communication unit. Specifically, the control unit is a CPU. The communication unit uses a mobile phone communication network as its communication method. The server 50 executes various processes by executing programs stored in the storage unit. The server 50 can also transmit signals to the mobile terminal 40 by executing communication processes.

[0021] The server 50 is capable of executing a bathing determination process. The bathing determination process is a process for determining when a subject has started bathing and when they have finished bathing. The server 50 executes the bathing determination process based on the detection results of the two bathing detection sensors 30. Specifically, the server 50 determines that the subject has taken a bath by acquiring detection signals from both the human presence sensor 31 and the flow rate sensor 32. After determining that the subject has taken a bath, the server 50 determines that the subject has finished bathing by acquiring non-detection signals from both the human presence sensor 31 and the flow rate sensor 32. In other words, the server 50 executes the bathing determination process based on the detection results of the human presence sensor 31 and the flow rate sensor 32. Note that "the server 50 is executable" means that the control unit of the server 50 is executable. The same applies to the following explanation.

[0022] The server 50 causes the biosensor 20 to execute the acquisition process. As described above, the acquisition process is a process for acquiring the subject's bioinformation BI over time. The server 50 causes the biosensor 20 to execute the acquisition process in any one of a first measurement mode, a second measurement mode, and a third measurement mode. Each measurement mode will be described later.

[0023] In the case of a pre-bathing period before the start of bathing is determined in the bathing determination process, i.e., when the subject is in a pre-bathing state, the server 50 causes the biosensor 20 to acquire biometric information BI in the first measurement mode in the acquisition process. Specifically, the server 50 resets the determination after a predetermined period has elapsed since the end of bathing was detected in the bathing determination process. The server 50 then defines the period from the reset of the determination until the next determination of the start of bathing as the pre-bathing period. Note that the predetermined period can be set to a period ranging from several tens of minutes to several hours, for example. Furthermore, the server 50 transmits a first signal to the mobile terminal 40 in response to resetting the determination as described above. The server 50 transmits the first signal to the mobile terminal 40. Upon receiving the first signal, the mobile terminal 40 transmits a first mode signal to the biosensor 20. The biosensor 20 then begins measurement in the first measurement mode in the acquisition process. After the power of the biosensor 20 is switched from off to on, the biosensor 20 performs measurement in the first measurement mode unless it receives a mode signal from the mobile terminal 40. In other words, the first measurement mode is the measurement mode in the initial state of the biosensor 20.

[0024] Furthermore, during the bathing period from when the start of bathing is determined in the bathing determination process until the end of bathing is determined, i.e., when the subject is bathing, the server 50 causes the biosensor 20 to acquire bioinformation BI in the second measurement mode in the acquisition process. Specifically, when the start of bathing is determined in the bathing determination process, the server 50 transmits a second signal to the mobile terminal 40. Upon receiving the second signal, the mobile terminal 40 transmits a second mode signal to the biosensor 20. Then, the biosensor 20 starts measurement in the second measurement mode in the acquisition process.

[0025] Furthermore, in the post-bathing period after the end of bathing is determined in the bathing determination process, i.e., when the subject is in a post-bathing state, the server 50 causes the biosensor 20 to acquire biometric information BI in the third measurement mode in the acquisition process. Specifically, when the server 50 determines that bathing has ended in the bathing determination process, it transmits a third signal to the mobile terminal 40. Upon receiving the third signal, the mobile terminal 40 transmits a third mode signal to the biosensor 20. Then, the biosensor 20 starts measurement in the third measurement mode in the acquisition process. As described above, the server 50 resets the determination after a predetermined period has elapsed since determining that bathing has ended. Therefore, the post-bathing period is a predetermined period after the end of bathing is determined in the bathing determination process.

[0026] The server 50 is capable of executing a determination process. The server 50 determines whether or not there is an abnormality in the subject's condition based on the transition of the biometric information BI acquired in the acquisition process. The condition for determining that there is an abnormality in the subject's condition is, for example, that both of the following two conditions are satisfied: The minimum blood oxygen saturation value obtained in the second measurement mode and the third measurement mode is smaller than the average blood oxygen saturation value obtained in the first measurement mode by a predetermined threshold or more. The maximum pulse value acquired in the second measurement mode and the third measurement mode is greater than the average pulse value acquired in the first measurement mode by a predetermined threshold value or more.

[0027] The server 50 is capable of executing an output process. The output process is a process of outputting the determination result of the determination process. Specifically, in the output process, the server 50 outputs the determination result of the determination process to the mobile terminal 40 and the external terminal 60 owned by the subject.

[0028] In this embodiment, the external terminal 60 is a PC installed in a hospital. Although not shown, the external terminal 60 includes a communication unit. In this embodiment, the communication unit uses a mobile phone communication network as its communication method. The external terminal 60 can receive signals from the server 50 via the communication unit.

[0029] <About measurement modes> As described above, the biosensor 20 executes the acquisition process in any one of the first, second, and third measurement modes. The first, second, and third measurement modes include blood oxygen saturation and pulse rate as types of bioinformation BI to be acquired.

[0030] In the first measurement mode, the biosensor 20 measures blood oxygen saturation and pulse rate as bioinformation BI every five minutes. The biosensor 20 then stores the measured blood oxygen saturation and pulse rate in the memory. The biosensor 20 then transmits the blood oxygen saturation and pulse rate to the mobile terminal 40 after each measurement. The mobile terminal 40 then transmits the blood oxygen saturation and pulse rate to the server 50.

[0031] In the first measurement mode, the biosensor 20 measures body temperature as bioinformation BI every five minutes. The biosensor 20 stores the measured body temperature in the storage unit. The biosensor 20 transmits the body temperature to the mobile terminal 40 every time it measures the body temperature. The mobile terminal 40 transmits the body temperature to the server 50.

[0032] In the first measurement mode, the biosensor 20 measures the acceleration of the subject as biometric information BI every second. The biosensor 20 stores the measured acceleration in the storage unit. The biosensor 20 transmits the acceleration to the mobile terminal 40 every time it measures it. The mobile terminal 40 transmits the acceleration to the server 50.

[0033] In the second measurement mode, the biosensor 20 measures blood oxygen saturation and pulse rate as bioinformation BI every second. The biosensor 20 then stores the measured blood oxygen saturation and pulse rate in the memory. The biosensor 20 then transmits the blood oxygen saturation and pulse rate to the mobile terminal 40 after each measurement. The mobile terminal 40 then transmits the blood oxygen saturation and pulse rate to the server 50.

[0034] In addition, in the second measurement mode, the biosensor 20 stops measuring the subject's body temperature. In addition, in the second measurement mode, the biosensor 20 stops measuring the subject's acceleration. That is, in the second measurement mode, the subject's body temperature and acceleration are not measured.

[0035] In this way, the first measurement mode and the second measurement mode differ in the types of biological information BI to be acquired. Specifically, the first measurement mode includes body temperature as a type of biological information BI to be acquired, while the second measurement mode does not include body temperature as a type of biological information BI to be acquired. Furthermore, the first measurement mode includes acceleration as a type of biological information BI to be acquired, while the second measurement mode does not include acceleration as a type of biological information BI to be acquired.

[0036] Furthermore, the first and second measurement modes differ in the frequency of measurement of the biological information BI. Specifically, the second measurement mode measures the blood oxygen saturation and pulse rate more frequently than the first measurement mode.

[0037] In this embodiment, the measurement frequency of the biological information BI in the third measurement mode and the type of biological information BI to be acquired are both the same as those in the second measurement mode. In other words, the measurement frequency of the biological information BI and the type of biological information BI to be acquired are different between the third measurement mode and the first measurement mode. Furthermore, the measurement frequency of the blood oxygen saturation and pulse rate is higher in the third measurement mode than in the first measurement mode.

[0038] <Processing performed by the health management system> An example of the processing executed by the health management system 10 will be described with reference to FIG. First, the biosensor 20 attached to the subject is powered on. With the power on, the biosensor 20 performs measurement in the first measurement mode. Then, the biosensor 20 transmits the bioinformation BI to the mobile terminal 40 every time it measures the bioinformation BI. Note that in FIG. 2, part of the transmission of the bioinformation BI from the biosensor 20 to the mobile terminal 40 is omitted.

[0039] Then, every time the mobile terminal 40 receives the biometric information BI, it transmits the biometric information BI to the server 50 via the second communication unit. The server 50 stores the biometric information BI. Note that in FIG. 2, part of the transmission of the biometric information BI from the mobile terminal 40 to the server 50 is omitted.

[0040] Assume that the subject starts bathing at a certain point in time. That is, the subject enters the bathroom. The human presence sensor 31 detects that the subject has started bathing and transmits a detection signal to the mobile terminal 40 via the communication unit. The mobile terminal 40 then transmits the detection signal received from the human presence sensor 31 to the server 50 via the second communication unit.

[0041] Furthermore, the flow rate sensor 32 detects that the subject has started bathing, and transmits a detection signal via the communication unit to the mobile terminal 40. The mobile terminal 40 then transmits the detection signal received from the flow rate sensor 32 to the server 50 via the second communication unit.

[0042] The server 50 executes the bathing determination process by acquiring the detection signals from each bathing detection sensor 30. In other words, the server 50 determines that the subject has started bathing by acquiring the detection signals.

[0043] Here, in response to the determination that bathing has started, the server 50 transmits a second signal to the mobile terminal 40. Upon receiving the second signal, the mobile terminal 40 transmits a second mode signal to the biosensor 20. Then, the biosensor 20 receives the second mode signal.

[0044] After the subject starts bathing, the biosensor 20 starts measurement in the second measurement mode in response to the second mode signal. Then, the biosensor 20 transmits the bioinformation BI to the mobile terminal 40 every time it measures the bioinformation BI. Then, every time the mobile terminal 40 receives the bioinformation BI, it transmits the bioinformation BI to the server 50 via the second communication unit. The server 50 stores the bioinformation BI.

[0045] Assume that at a certain point in time, the subject finishes bathing. In other words, the subject leaves the bathroom. Flow sensor 32 detects that the subject has finished bathing and transmits a non-detection signal to mobile terminal 40 via the communication unit. Mobile terminal 40 then transmits the non-detection signal received from flow sensor 32 to server 50 via the second communication unit.

[0046] Furthermore, the human presence sensor 31 detects that the subject has started bathing, and transmits a detection signal via the communication unit to the mobile terminal 40. Then, the mobile terminal 40 transmits a non-detection signal received from the human presence sensor 31 to the server 50 via the second communication unit.

[0047] The server 50 executes the bathing determination process by acquiring a non-detection signal from each bathing detection sensor 30. In other words, the server 50 determines that the subject has finished bathing by acquiring a non-detection signal.

[0048] Here, in response to the determination that the bathing has ended, the server 50 transmits a third signal to the mobile terminal 40. Upon receiving the third signal, the mobile terminal 40 transmits a third mode signal to the biosensor 20. Then, the biosensor 20 receives the third mode signal.

[0049] The biosensor 20 starts measurement in the third measurement mode in response to the third mode signal. Then, the biosensor 20 transmits the bioinformation BI to the mobile terminal 40 every time it measures the bioinformation BI. Then, every time the mobile terminal 40 receives the bioinformation BI, it transmits the bioinformation BI to the server 50 via the second communication unit. The server 50 stores the bioinformation BI.

[0050] The server 50 resets the determination after a predetermined period has elapsed since determining that the subject has finished bathing. Then, in response to resetting the determination, the server 50 transmits a first signal to the mobile terminal 40. Upon receiving the first signal, the mobile terminal 40 transmits a first mode signal to the biosensor 20. Then, the biosensor 20 receives the first mode signal. In response to the first mode signal, the biosensor 20 starts measurement in the first measurement mode. In this way, when a predetermined period has elapsed after the subject has finished bathing, the measurement mode of the biosensor 20 returns to the initial state, the first measurement mode.

[0051] Furthermore, the server 50 executes a determination process in response to resetting the determination. The server 50 determines whether or not there is an abnormality in the subject based on the transition of the biological information BI acquired in the acquisition process. In this embodiment, the server 50 determines whether or not there is an abnormality in the biological information BI based on the blood oxygen saturation and pulse rate acquired in each measurement mode. The conditions for determining whether or not there is an abnormality in the biological information BI are as described above.

[0052] The server 50 can execute an output process in response to the determination of whether or not there is an abnormality in the biometric information BI in the determination process. The output process is a process of outputting the determination result in the determination process. Specifically, in the output process, the server 50 outputs the determination result in the determination process to the mobile terminal 40 and the external terminal 60 owned by the subject.

[0053] <Effects of this embodiment> (1) In the above embodiment, in the pre-bathing period, the biosensor 20 acquires the biometric information BI in the first measurement mode. In addition, in the bathing period, the biosensor 20 acquires the biometric information BI in the second measurement mode. The first measurement mode and the second measurement mode differ in the measurement frequency of the biometric information BI and the type of biometric information BI to be acquired. In other words, with this configuration, the acquisition process can be performed under conditions that are favorable for acquiring the biometric information BI of the subject in the special environment of bathing. Therefore, with the above configuration, it is possible to prevent the acquisition of too much or too little biometric information BI.

[0054] (2) In the above embodiment, the second measurement mode measures the biological information BI more frequently than the first measurement mode. With this configuration, the biological information BI is acquired at a higher density while the subject is bathing than before the subject starts bathing. Therefore, changes in the biological information BI while the subject is bathing can be detected with high accuracy.

[0055] (3) In the post-bathing period, although the subject is not bathing, the biometric information BI is likely to fluctuate due to the influence of bathing. In the above embodiment, in the post-bathing period, the biometric sensor 20 acquires the biometric information BI in the third measurement mode. Furthermore, in the above configuration, the third measurement mode and the first measurement mode have different measurement frequencies for the biometric information BI and different types of biometric information BI to be acquired. In other words, with this configuration, the acquisition process can be performed under conditions that are favorable for acquiring the biometric information BI of the subject in the special environment of after bathing. Therefore, with the above configuration, it is possible to prevent excess or deficiency in the acquired biometric information BI.

[0056] (4) In the above embodiment, the third measurement mode measures the biological information BI more frequently than the first measurement mode. With this configuration, the biological information BI is acquired at a higher density after the subject has taken a bath than before the subject has taken a bath. Therefore, changes in the biological information BI after the subject has taken a bath can be detected with high accuracy.

[0057] (5) As described above, in the post-bathing period after the bathing determination process determines that the bathing has ended, the biological information BI is likely to fluctuate due to the effects of bathing. In the above embodiment, the second measurement mode and the third measurement mode have the same measurement frequency of the biological information BI and the same type of biological information BI to be acquired. In this way, the biological information BI can be acquired in the post-bathing period as well as in the bathing period.

[0058] (6) During bathing, the biosensor 20 may not be able to properly detect the subject's body temperature due to the influence of the hot water in the bathtub or the hot water from the shower. In other words, the body temperature measured by the biosensor 20 while the subject is bathing is unreliable and is difficult to refer to as a parameter for determining whether or not there is an abnormality in the bioinformation BI. In the above embodiment, the second measurement mode does not include body temperature as a type of bioinformation BI to be acquired. This prevents an increase in the amount of data required to transmit the bioinformation BI and an increase in the amount of data in the memory unit of the server 50. Furthermore, by reducing the amount of data transmitted, battery consumption of the biosensor 20 can be reduced.

[0059] (7) The subject's acceleration is used to identify the subject's movements, such as the number of steps taken. On the other hand, it is unlikely that the subject will be walking or running while bathing, so there is little need to detect acceleration. In the above embodiment, the second measurement mode does not include acceleration as a type of biometric information BI to be acquired. Therefore, this configuration makes it possible to omit the acquisition of less necessary data.

[0060] (8) In subjects with a history of heart failure, blood oxygen concentration and pulse rate are likely to change between bathing and not bathing. In the above embodiment, the first measurement mode, the second measurement mode, and the third measurement mode include one or more types of bioinformation BI selected from blood oxygen saturation and pulse rate. Therefore, if the bioinformation BI includes one or more types selected from blood oxygen saturation and pulse rate, it is easier to determine abnormalities in the subject, specifically, abnormalities in the condition of heart failure, in the determination process.

[0061] (9) In the above embodiment, the server 50 executes the bathing determination process based on the detection results of the human presence sensor installed in the bathroom that can detect the subject and the flow rate sensor installed in the shower in the bathroom. Because the start and end of the subject's bathing can be determined based on the detection results of the two bathing detection sensors 30, erroneous determinations are unlikely to occur.

[0062] (10) In the above embodiment, the second measurement mode and the third measurement mode have the same content, but the server 50 transmits a third signal when it determines that bathing has ended. This allows the mobile terminal 40 and the biosensor 20 to know that it is the post-bathing period. If it is possible to know that it is the post-bathing period, for example, the biosensor 20 and the mobile terminal 40 can label the acquired bioinformation BI as data from the post-bathing period.

[0063] <Example of change> The above-described embodiment and the following modified examples can be implemented in combination with each other to the extent that no technical contradiction occurs.

[0064] In the above embodiment, the mobile terminal 40 does not have to be owned by the subject. Furthermore, the output destination of the determination result is not limited to a smartphone, and may be any device capable of communication. In other words, the mobile terminal 40 may be replaced by a desktop computer or the like.

[0065] In the above embodiment, the communication methods between the biosensor 20, each bathing detection sensor 30, the mobile terminal 40, the server 50, and the external terminal 60 are not limited to those described in the above embodiment. For example, the communication method may be determined by various standards such as IEEE 802.11. Furthermore, the communication method is not limited to wireless communication. For example, the biosensor 20 and the mobile terminal 40 may communicate via a wired connection. Furthermore, the biosensor 20 may not have a communication function with the mobile terminal 40. In this case, for example, the biosensor 20 may be able to communicate with a cradle corresponding to the biosensor 20, and the cradle may be able to communicate with the mobile terminal 40 via a wired connection. In this way, if the biosensor 20 does not have a communication unit for communicating with the mobile terminal 40, the biosensor 20 can be designed to be correspondingly smaller.

[0066] In the above embodiment, the biosensor 20 is not limited to a sensor that functions as a pulse oximeter, a temperature sensor, and an acceleration sensor. The biosensor 20 may be capable of acquiring at least one piece of bioinformation BI of the subject. The health management system 10 may also be equipped with multiple biosensors 20, with one measuring blood oxygen saturation and another measuring pulse rate. In the above embodiment, for convenience, the term "pulse rate" refers to the number of pulses that can be counted due to cardiac contraction, and includes the heart rate, which is the number of cardiac pulses.

[0067] In the above embodiment, the types of biometric information BI are not limited to the four examples in the above embodiment. In the above embodiment, the biosensor 20 may start and end measurement of the bioinformation BI at timings other than when the power is turned on or off. For example, the server 50 may transmit a measurement start signal via the mobile terminal 40, causing the biosensor 20 to start measurement of the bioinformation BI.

[0068] In the first and second embodiments, the biosensor 20 does not have to transmit the biometric information BI to the mobile terminal 40 every time it measures the biometric information BI. The biosensor 20 may store multiple pieces of biometric information BI in a storage unit thereof and transmit the pieces of biometric information BI at predetermined intervals. The same applies to the mobile terminal 40. The mobile terminal 40 may transmit multiple pieces of biometric information BI to the server 50 all at once.

[0069] In the above embodiment, the health management system 10 is not limited to one including the biosensor 20, the mobile terminal 40, the server 50, and the external terminal 60. Any of the components in the health management system 10 may be capable of executing the acquisition process, the bathing determination process, the determination process, and the output process. Furthermore, these processes may be executed by one component or by different components. For example, in the above embodiment, the bathing detection sensor 30 may execute the bathing determination process, and the mobile terminal 40 may execute the determination process and the output process.

[0070] In the above embodiment, as long as the determination process is a process for determining abnormalities in a subject based on the transition of the biometric information BI, the determination method and conditions for the determination are not limited to those in the above embodiment. Furthermore, the transition of the biometric information BI may include the transition of at least one type of biometric information BI.

[0071] In the above embodiment, the output process does not have to be executed. For example, the output process may be executed only when a device such as the mobile terminal 40 requests the output of the determination result.

[0072] In the above embodiment, for example, the subject may input a signal indicating that bathing has started to the mobile device 40 when starting to bathe. Furthermore, the subject may input a signal indicating that bathing has ended to the mobile device 40 when completing the input. The mobile device 40 may transmit these signals to the server 50, and the server 50 may execute a bathing determination process based on these signals. With the above-described configuration, the health management system 10 does not necessarily have to include the bathing detection sensor 30.

[0073] In the above embodiment, the bathing detection sensor 30 is not limited to the human presence sensor 31 and the flow rate sensor 32. For example, the bathing detection sensor 30 may be an open / close sensor attached to the bathroom door and capable of detecting whether the bathroom door is open or closed. In this case, the server 50 may determine, in the bathing determination process, whether the subject has started bathing based on the open / close sensor detecting that the bathroom door has switched from an open state to a closed state. Furthermore, in the bathing determination process, the server 50 may determine whether the subject has finished bathing based on the open state being detected by the open / close sensor for the first time after determining that the subject has started bathing.

[0074] Alternatively, the bathing detection sensor 30 may be a human presence sensor attached to the anteroom of the bathroom and capable of detecting the subject. In this case, the server 50 may determine, in the bathing determination process, whether the subject has started bathing based on the human presence sensor going from a state of detecting a person to a state of not detecting a person to a state of not detecting a person. After determining the start of bathing in the bathing determination process, the server 50 may determine whether the subject has finished bathing based on the human presence sensor going from a state of not detecting a person to a state of detecting a person.

[0075] The bathing detection sensor 30 may also be an acceleration sensor attached to the subject. In this case, the server 50 detects the subject's movements based on the values ​​detected by the acceleration sensor in the bathing determination process, and determines the start and end of the bathing session based on the similarity between the detected movements and predetermined bathing movements. The acceleration sensor may also function as the acceleration sensor in the biosensor 20.

[0076] In this way, the bathing determination process may be performed based on the detection results of an open / close sensor attached to the bathroom door that can detect whether the bathroom door is open or closed, a motion sensor attached to the bathroom or bathroom anteroom that can detect the subject, or a flow sensor attached to the shower in the bathroom. However, the bathing determination process may also be performed based on the detection results of one or more of the above sensors. Furthermore, any sensor other than the above-mentioned sensors that can detect the subject's bathing may also be used as the bathing detection sensor 30. For example, the bathing determination process may be performed based on the detection results of a biosensor 20 attached to the subject that can acquire the subject's biometric information BI. In this case, for example, the server 50 may determine the subject's start of bathing in the bathing determination process based on the subject's body temperature rising by a predetermined value or more. Furthermore, the server 50 may determine the subject's end of bathing in the bathing determination process based on the subject's body temperature falling by a predetermined value or more. Furthermore, for example, the server 50 may determine the subject's start of bathing in the bathing determination process based on the subject's pulse rate rising by a predetermined value or more. Furthermore, the server 50 may determine whether the subject has finished bathing in the bathing determination process based on a decrease in the subject's pulse rate by a predetermined value or more. For example, the server 50 may determine whether the subject has started bathing in the bathing determination process based on a decrease in the subject's oxygen saturation by a predetermined value or more. For example, the server 50 may determine whether the subject has finished bathing in the bathing determination process based on an increase in the subject's oxygen saturation by a predetermined value or more. As described above, the bathing determination process may be performed based on the acceleration of the subject detected by the biosensor 20. That is, the bathing determination process may be performed based on the detection results of two or more of the biosensors 20 attached to the subject and capable of acquiring the subject's bioinformation BI, in addition to the open / close sensor, human presence sensor, and flow sensor described above.

[0077] <Example of changing measurement mode> In the above embodiment, the biosensor 20 does not have to acquire the bioinformation BI in the third measurement mode. That is, the biosensor 20 may stop acquiring the bioinformation BI after taking a bath.

[0078] In the above embodiment, the first measurement mode and the second measurement mode may differ in at least one selected from the measurement frequency of the biological information BI and the type of the biological information BI to be acquired. That is, the first measurement mode and the second measurement mode may differ only in the measurement frequency, or the first measurement mode and the second measurement mode may differ only in the type of the biological information BI to be acquired.

[0079] In the above embodiment, the second measurement mode may measure the biological information BI at a lower frequency than the first measurement mode, or may measure the same frequency. For example, if the type of biological information BI is one that is likely to fluctuate before bathing, measuring the biological information BI at a higher frequency in the first measurement mode than in the second measurement mode can prevent the biological information BI from being acquired too much or too little.

[0080] In the above embodiment, the first measurement mode does not have to include body temperature as a type of biological information BI to be acquired.Furthermore, the first measurement mode does not have to include acceleration as a type of biological information BI to be acquired.

[0081] In the above embodiment, the second measurement mode may include body temperature as a type of biological information BI to be acquired. The second measurement mode may include acceleration as a type of biological information BI to be acquired.

[0082] In the above embodiment, the first, second, and third measurement modes may include one or more types of biological information BI selected from blood oxygen saturation and pulse rate as the types of biological information BI to be acquired. However, as long as there is at least one type of biological information BI that is commonly acquired in each measurement mode, blood oxygen saturation and pulse rate do not have to be included as types of biological information BI to be acquired in each measurement mode.

[0083] In the above embodiment, the second measurement mode and the third measurement mode may differ in one or more of the measurement frequency of the biological information BI and the type of the biological information BI to be acquired. As a result, the measurement frequency of the biological information BI in the third measurement mode may be the same as the measurement frequency of the biological information BI in the first measurement mode. Furthermore, the measurement frequency of the biological information BI in the third measurement mode may be lower than that in the first measurement mode. Furthermore, the type of biological information BI acquired in the third measurement mode may be the same as the type of biological information BI acquired in the first measurement mode.

[0084] In the above embodiment, if the measurement frequency of the biological information BI and the type of biological information BI to be acquired are the same in the second measurement mode and the third measurement mode, the transmission of the third signal and the third mode signal may be omitted.

[0085] In the above embodiment, the measurement mode of the biosensor 20 in the initial state is not limited to the first measurement mode. In the above embodiment, the measurement modes are not limited to the first, second, and third measurement modes. Furthermore, other measurement modes may be set. For example, during a predetermined period after bathing, the biosensor 20 may acquire bioinformation BI in the third measurement mode for a predetermined period, and then acquire bioinformation BI in a fourth measurement mode that is less frequent than the third measurement mode but more frequent than the first measurement mode.

[0086] In the above embodiment, the biological information BI in each measurement mode does not have to be measured at equal intervals. "The biological information BI is measured frequently" means that the number of times the biological information BI is measured per unit time is large.
