Biological information transmitter

The present invention relates to a biological information transmitting apparatus that transmits biological information measured by a sensor attached to a human body.

2. Description of the Related Art Conventionally, there is known a biological information transmitting apparatus that measures biological information indicating a human body state such as body temperature, heartbeat, and pulse using a sensor attached to the human body and transmits the measured biological information (for example, a patent Reference 1). A conventional biological information transmitting device includes a wireless communication unit that wirelessly transmits biological information, and transmits predetermined biological information to a management device connected via a wireless communication line.

International Publication No. 2008/136050

However, since the conventional biological information transmitting apparatus is connected to the management apparatus via a single wireless communication line, there is a problem in that the biological information cannot be transmitted if the state of the wireless communication line is bad. In particular, when it is necessary to monitor biological information of a person who needs prompt treatment when the physical condition deteriorates, such as an elderly person or a sick person, the biological information is transmitted to the management device due to a bad state of the wireless communication line. Otherwise, there was a risk of overlooking the deterioration of the physical condition of the elderly and sick.

∙ Wireless communication lines are easily affected by the surrounding environment, and the communication quality varies depending on the location, time of day, and weather. In particular, since the number of terminals using wireless communication lines has increased in recent years, when there are many terminals using wireless communication lines in the vicinity, there is a probability that the wireless communication line cannot be used at the timing when biometric information should be transmitted. It was high.

Therefore, the present invention has been made in view of these points, and an object of the present invention is to provide a biological information transmitting apparatus capable of transmitting biological information even when communication cannot be performed with one wireless communication line.

In order to solve the above-described problem, in the present invention, a biological information transmitting apparatus that performs wireless communication with a wireless terminal, a biological information acquisition unit that acquires biological information of a user, and the biological information as first wireless communication A first communication unit for transmitting via a line, a second communication unit for transmitting biological information via a second wireless communication line different from the first wireless communication line, and any of the first communication unit and the second communication unit for transmitting biological information. A communication control unit that transmits the information and a determination unit that determines whether the biological information exceeds a predetermined allowable range, and the determination unit determines that the biological information exceeds a predetermined allowable range, The communication control unit causes the first communication unit to transmit warning information to the wireless terminal via the first wireless communication line, and transmits the warning information to the wireless terminal via the second wireless communication line to the second communication unit. Provided is a biological information transmitting apparatus. Since the biometric information transmitting apparatus can transmit biometric information via the first radio communication line and the second radio communication line, even if the state of one of the radio communication lines is bad, it is ensured. Biological information can be transmitted to

For example, when the determination unit determines that the state where the biological information exceeds the predetermined allowable range continues for a time longer than the predetermined time, the communication control unit transmits the warning information. By operating the communication control unit in this manner, it is possible to prevent the warning information from being transmitted only when a temporary abnormal state occurs.

The communication control unit may cause the biological information to be transmitted to the one of the first communication unit and the second communication unit that has received response information that is a response to the warning information. By transmitting the biological information after the response information is received by the communication control unit, it is possible to prevent wasteful power consumption by transmitting the biological information using a wireless communication line in a state where communication is not possible.

In the case where the first communication unit does not receive the response information until a predetermined time elapses after the warning information is transmitted to the first communication unit whose transmission power is lower than that of the second communication unit. In addition, the warning information may be transmitted to the second communication unit. By controlling the communication control unit in this way, it is possible to reduce the frequency at which the warning information is transmitted via the wireless communication line, and thus it is possible to suppress power consumption.

The biometric information transmission device further includes a position detection unit that detects the position of the biometric information transmission device, and a storage control unit that associates the communication history with the position and stores the communication history in the storage unit. The warning information may be transmitted first to any one of the first communication unit and the second communication unit selected based on the communication history at the position detected by the unit. By controlling the communication control unit in this way, the warning information can be transmitted using a wireless communication line suitable for the position.

The biological information transmitting apparatus further includes an acceleration detection unit that detects a user's motion acceleration, and a housing unit that houses the biological information acquisition unit, the first communication unit, the second communication unit, the communication control unit, and the determination unit. The communication control unit causes the first communication unit and the second communication unit that transmitted the warning information to transmit acceleration information indicating the motion acceleration, and the acceleration detection unit includes a plurality of restrictions that limit a movement range of the acceleration detection unit. You may be provided in the housing | casing part in the state pinched | interposed by the member. When the acceleration detection unit has the above-described configuration, the acceleration detection unit can be easily formed integrally with the housing unit, and failure due to an impact such as dropping can be prevented.

The biometric information acquisition unit has a plurality of electrode units provided on the surface of the housing unit, and the housing unit has a structure in which the direction of the surface of a predetermined region near at least one of the plurality of electrode units changes. You may do it. Since the housing portion has such a structure, the electrode can be brought into close contact with the body regardless of the shape of the body, so that the measurement accuracy of biological information can be improved.

According to the present invention, there is an effect that biometric information can be transmitted even when communication cannot be performed with one wireless communication line.

<First Embodiment>
[Configuration Example of Biometric Information Management System 10 Using Biological Information Transmitting Device 100]
FIG. 1 shows a configuration example of a biological information management system 10 in which the biological information transmitting apparatus 100 of the first embodiment is used. The biological information management system 10 includes a biological information transmission device 100, a wireless terminal 200-1, a wireless terminal 200-2, a server 300, and a wireless portable terminal 400.

The biological information transmitting apparatus 100 performs wireless communication with at least one of the wireless terminal 200-1 and the wireless terminal 200-2 via either the first wireless communication line 510 or the second wireless communication line 520. . The wireless terminal 200-1 and the wireless terminal 200-2 are mobile wireless terminals such as smartphones or wireless communication capable of communicating with at least one of the server 300 and the wireless mobile terminal 400 via the mobile phone line 530 and the network 50. An information terminal such as a PC having a function. The network 50 is, for example, the Internet or a local area network.

The biological information transmitting apparatus 100 transmits the biological information of the user wearing the biological information transmitting apparatus 100 via either the first wireless communication line 510 or the second wireless communication line 520. The biological information transmitting apparatus 100 receives an instruction from at least one of the wireless terminal 200-1 and the wireless terminal 200-2 received via either the first wireless communication line 510 or the second wireless communication line 520. In response, measurement of biological information may be started.

[Configuration Example of Biological Information Transmitting Device 100]
FIG. 2 shows a configuration example of the biological information transmitting apparatus 100. The biological information transmitting apparatus 100 includes a biological information acquisition unit 110, a first communication unit 120, a second communication unit 130, a communication control unit 140, and a determination unit 150. The biological information transmitting apparatus 100 receives power supply from, for example, a battery and operates the biological information acquisition unit 110, the first communication unit 120, the second communication unit 130, the communication control unit 140, and the determination unit 150.

The biological information acquisition unit 110 is worn on a part of the user's body (for example, the chest), and acquires biological information such as body temperature, heart rate, and heart rate waveform. The biological information acquisition unit 110 includes, for example, a body temperature sensor and a heart rate sensor.

The first communication unit 120 transmits the biological information through the first wireless communication line 510. The second communication unit 130 transmits the biological information through a second wireless communication line 520 that is different from the first wireless communication line 510. The first wireless communication line 510 is, for example, a wireless communication line suitable for terminal-to-terminal communication at a shorter distance than the second wireless communication line 520. The first wireless communication line 510 is, for example, Bluetooth (registered trademark), and the second wireless communication line 520 is, for example, Wi-Fi or a specific low-power wireless line. The first wireless communication line 510 may be Wi-Fi, and the second wireless communication line 520 may be a mobile phone line. The first communication unit 120 transmits biological information with a transmission power smaller than that of the second communication unit 130.

The communication control unit 140 causes the biological information to be transmitted to either the first communication unit 120 or the second communication unit 130. The communication control unit 140 is, for example, a microprocessor that controls the first communication unit 120 and the second communication unit 130 by executing a program stored in a storage medium. The communication control unit 140 inputs the biometric information acquired by the biometric information acquisition unit 110 to at least one of the first communication unit 120 and the second communication unit 130 and instructs to transmit the input biometric information.

The determination unit 150 determines whether the biological information exceeds a predetermined allowable range. For example, the determination unit 150 compares the reference body temperature and the reference heart rate stored in a storage medium such as a memory in advance with the body temperature and the heart rate acquired by the first communication unit 120, and the first communication unit 120 acquires It is determined whether at least one of the body temperature and the heart rate exceeds the reference body temperature or the reference heart rate. The determination unit 150 may determine whether the heartbeat waveform acquired by the first communication unit 120 is within an allowable range of a heartbeat waveform stored in advance.

When the determination unit 150 determines that the biometric information exceeds a predetermined allowable range, the communication control unit 140 sends warning information for warning the abnormality of the biometric information to the first communication unit 120 as the first wireless communication line. The second communication unit 130 is caused to transmit the warning information to the wireless terminal 200-1 via the second wireless communication line 520. The communication control unit 140 may cause the first communication unit 120 and the second communication unit 130 to transmit biological information together with the warning information.

For example, when at least one of body temperature, heart rate, and heart rate waveform exceeds an allowable range, the communication control unit 140 uses the two wireless communication lines of Bluetooth and Wi-Fi to connect to the wireless terminal 200-1. Send warning information. If the communication control unit 140 transmits warning information using a plurality of wireless communication lines, even if the state of one of the wireless communication lines is bad, the warning is given if the state of the other wireless communication line is good. Information is normally sent to the wireless terminal 200-1.

Upon receiving the warning information, the wireless terminal 200-1 notifies the user of the wireless terminal 200-1 that the warning information has been received. The wireless terminal 200-1 transfers the warning information to another terminal (for example, the server 300 or the wireless portable terminal 400) connected via the network 50, thereby distant from the user of the biological information transmitting apparatus 100. The person who is present may be notified that an abnormality has occurred in the biometric information of the user of the biometric information transmitting apparatus 100.

Note that the communication control unit 140 determines that the first communication unit 120 determines that the determination unit 150 has continued the state in which the biological information exceeds the predetermined allowable range for a time longer than the predetermined time. The warning information may be transmitted to at least one of the second communication units 130. The communication control unit 140 may determine the time from when the biological information exceeds the predetermined allowable range until the warning information is transmitted, according to the relationship between the biological information and the predetermined allowable range. For example, the communication control unit 140 causes the warning information to be transmitted in a shorter time after the biological information exceeds a predetermined allowable range as the deviation amount of the biological information with respect to the allowable range is larger. The communication control unit 140 may determine the time until the warning information is transmitted after the biological information exceeds the predetermined allowable range according to the type of the biological information that exceeds the predetermined allowable range.

[Example of communication sequence]
FIG. 3 shows an example of a communication sequence when the biological information transmitting apparatus 100 transmits warning information. When the determination unit 150 determines that the biological information is abnormal, the communication control unit 140 instructs the first communication unit 120 and the second communication unit 130 to transmit warning information. The first communication unit 120 and the second communication unit 130 transmit warning information to the wireless terminal 200-1 in response to a transmission instruction from the communication control unit 140.

Upon receiving the warning information, the wireless terminal 200-1 transmits response information that is a response to the warning information. When receiving the warning information from the first communication unit 120, the wireless terminal 200-1 transmits response information to the first communication unit 120. When receiving the warning information from the second communication unit 130, the wireless terminal 200-1 transmits the response information to the second communication unit 130. Response information.

When the first communication unit 120 and the second communication unit 130 receive the response information from the wireless terminal 200-1, the first communication unit 120 and the second communication unit 130 output a response notification that notifies the communication control unit 140 that the response information has been received. The communication control unit 140 causes the biometric information to be transmitted to the one of the first communication unit 120 and the second communication unit 130 that has received the response information. Specifically, when receiving a response notification from the first communication unit 120, the communication control unit 140 causes the first communication unit 120 to transmit biological information indicating an abnormal state. When receiving a response notification from the second communication unit 130, the communication control unit 140 causes the second communication unit 130 to transmit biological information indicating an abnormal state.

The communication control unit 140 does not transmit the biological information to all the communication units that have received the response information out of the first communication unit 120 and the second communication unit 130, but only the communication unit that has received the response information first. Biometric information may be transmitted. In addition, the communication control unit 140 causes the first communication unit 120 and the second communication unit 130 to wait for reception of instructions from the radio terminal 200-1 and the radio terminal 200-2, and the first communication unit 120 and the second communication unit 130 The warning information and the biological information may be transmitted to the communication unit that has received the instruction in the unit 130. The communication control unit 140 can suppress power consumption by not transmitting the same biological information through a plurality of wireless communication lines.

As described above, according to the first embodiment, when an abnormal state occurs in the biological information, the biological information transmitting apparatus 100 uses the first wireless communication line 510 and the second wireless communication line 520 to issue warning information. Can be sent. Therefore, even if the state of either the first wireless communication line 510 or the second wireless communication line 520 is not good, warning information can be reliably transmitted to the wireless terminal 200-1. In addition, the user of the wireless terminal 200-1 can take prompt action on the person wearing the biological information transmitting apparatus 100.

<Second Embodiment>
[Use multiple wireless communication lines sequentially]
FIG. 4 shows an example of a communication sequence of the biological information transmitting apparatus 100 according to the second embodiment. The communication control unit 140 sends response information that is a response to the warning information until a predetermined time elapses after the first communication unit 120 having lower transmission power than the second communication unit 130 transmits the warning information. When the first communication unit 120 does not receive, the second communication unit 130 transmits warning information.

For example, when the determination unit 150 determines that the biological information exceeds a predetermined allowable range, the communication control unit 140 first causes the first communication unit 120 that performs wireless communication using Bluetooth to transmit warning information, Wait until time has passed. If the communication control unit 140 receives a response notification from the first communication unit 120 before the predetermined time has elapsed, the communication control unit 140 causes the first communication unit 120 to transmit biometric information. If the communication control unit 140 does not receive a response notification from the first communication unit 120 even after a predetermined time has elapsed, the communication control unit 140 transmits warning information to the second communication unit 130 that performs wireless communication using Wi-Fi.

For example, the communication control unit 140 sends warning information to the first communication unit 120 according to the state of the biological information indicated by the type of biological information that exceeds a predetermined allowable range or the amount that exceeds the predetermined allowable range. You may determine the time after making it transmit, and making the 2nd communication part 130 transmit warning information. By controlling the communication control unit 140 in this way, when the urgency is high, the warning information is promptly transmitted using a plurality of wireless communication lines, and when the urgency is low, the power consumption is reduced as much as possible. Can be suppressed.

The communication control unit 140 detects the remaining amount of the battery that operates the biological information transmitting apparatus 100, and transmits warning information to the first communication unit 120 according to the remaining amount of the battery, and then warns the second communication unit 130. You may determine the time until it transmits information. For example, when the remaining battery level is greater than a predetermined value, the communication control unit 140 causes the second communication unit 130 to wait for a first time after the first communication unit 120 transmits warning information. When the warning information is transmitted and the remaining battery level is equal to or less than the predetermined value, the second communication is performed when a second time shorter than the first time elapses after the first communication unit 120 transmits the warning information. The warning information is transmitted to the unit 130.

The communication control unit 140 may determine which of the first communication unit 120 and the second communication unit 130 should transmit the warning information according to the relationship between the biological information and the predetermined allowable range. For example, when the biological information deviates more than a predetermined amount from the allowable range, the communication control unit 140 causes the first communication unit 120 and the second communication unit 130 to simultaneously transmit warning information, and the biological information from the allowable range. If the information does not deviate more than a predetermined amount, the warning information may be transmitted to at least one of the first communication unit 120 and the second communication unit 130 first.

As described above, the communication control unit 140 preferentially uses the communication unit having the smaller transmission power among the first communication unit 120 and the second communication unit 130 to transmit the warning information and the biological information, thereby reducing the power consumption. It is possible to reliably report that an abnormality has occurred in the biological information while suppressing. In general, the distance at which information can be transmitted through a wireless communication line is determined according to transmission power. Therefore, according to the biological information transmitting apparatus 100 according to the present embodiment, when the wireless terminal 200-1 is near the biological information transmitting apparatus 100, the warning information is transmitted through the first wireless communication line 510, and the wireless terminal When the response information from 200-1 cannot be received, the transmission power is increased, so that the warning information and the biological information can be obtained even when the wireless terminal 200-1 is not within the communicable distance of the first wireless communication line 510. Information can be sent.

<Third Embodiment>
[Send to multiple wireless terminals]
5 and 6 show an example of a communication sequence of the biological information transmitting apparatus 100 according to the third embodiment. In the present embodiment, the communication control unit 140 causes at least one of the first communication unit 120 and the second communication unit 130 to transmit warning information to the radio terminal 200-1 and the radio terminal 200-2. For example, the communication control unit 140 first causes the first communication unit 120 having transmission power smaller than that of the second communication unit 130 to simultaneously transmit warning information to the radio terminal 200-1 and the radio terminal 200-2.

Next, when the first communication unit 120 does not receive the response information even after a predetermined time has elapsed since the first communication unit 120 has transmitted the warning information, the communication control unit 140 sends the response information to the second communication unit 130. The warning information may be transmitted to the wireless terminal 200-1 and the wireless terminal 200-2. When the first communication unit 120 receives the response information from at least one of the radio terminal 200-1 and the radio terminal 200-2, the communication control unit 140 sends the response information to the radio terminal 200 that has transmitted the response information to the first communication unit 120. Send biometric information.

As described above, the communication control unit 140 causes the first communication unit 120 and the second communication unit 130 to transmit warning information to the plurality of wireless terminals 200, whereby the wireless terminal 200-1 and the wireless terminal 200-2 Even when any one of these is not in a position where communication with the first communication unit 120 and the second communication unit 130 is possible, the biological information transmitting apparatus 100 can notify that abnormality has occurred in the biological information.

<Fourth Embodiment>
[Use location information]
FIG. 7 shows a configuration example of the biological information transmitting apparatus 100 according to the fourth embodiment. The biological information transmitting apparatus 100 illustrated in FIG. 7 is different from the biological information transmitting apparatus 100 illustrated in FIG. 2 in that it further includes a position detection unit 160, a storage control unit 170, and a storage unit 180, and is the same in other respects.
The position detection unit 160 detects the position of the biological information transmission device. The position detection unit 160 includes, for example, a GPS (Global Positioning System) receiver, and outputs latitude / longitude information of the biological information transmitting apparatus 100 based on radio waves received from a satellite.

The storage control unit 170 stores the communication history in the storage unit 180 in association with the position. The storage unit 180 is a storage medium such as a memory capable of writing and reading. Specifically, each time the warning information is transmitted, the storage control unit 170 acquires the position information from the position detection unit 160, and stores the acquired position information and the wireless communication line type and the communication result that transmitted the warning information. 180. The storage control unit 170, for example, in the communication history that the response information has not been sent from the wireless terminal 200-1 to the warning information transmitted by the first communication unit 120 at the position A or at the position B The communication history that the response information is received from the wireless terminal 200-1 with respect to the warning information transmitted by the communication unit 130 is stored in the storage unit 180. The storage control unit 170 may cause the storage unit 180 to store the date and time when the warning information is transmitted and the information related to the other party who transmitted the warning information in the communication history.

The communication control unit 140 causes the warning information to be transmitted first to any one of the first communication unit 120 and the second communication unit 130 selected based on the communication history at the position detected by the position detection unit 160. Specifically, the communication control unit 140 has received response information for warning information transmitted in the past within a predetermined range from the position detected by the position detection unit 160 of the first communication unit 120 and the second communication unit 130. Alert information is sent to the person with the highest probability first. Furthermore, the communication control unit 140 may cause the warning information to be transmitted first to a person having a higher probability of receiving response information to the warning information transmitted to the same party in the past at the same time.

As described above, according to the biological information transmitting apparatus 100 according to the present embodiment, the type of the wireless communication line used for transmitting the warning information is selected based on the past communication history at the position where the warning information is to be transmitted, First, since the warning information is transmitted using the selected wireless communication line, it is possible to improve the probability that the warning information can be transmitted in a short time while suppressing power consumption.

<Fifth Embodiment>
[Equipped with acceleration sensor]
FIG. 8 shows a configuration example of the biological information transmitting apparatus 100 according to the fifth embodiment. The biological information transmitting apparatus 100 shown in FIG. 8 differs from the biological information transmitting apparatus 100 shown in FIG. 2 in having an acceleration detecting unit 190, and is the same in other respects. The acceleration detection unit 190 detects the user's motion acceleration. The acceleration detection unit 190 has, for example, a MEMS (Micro Electro Mechanical Systems) structure, and detects acceleration based on a change in electrical characteristics due to a change in position in a minute movable unit supported by a beam structure. The communication control unit 140 causes the first communication unit 120 and the second communication unit 130 that have transmitted the warning information to transmit acceleration information indicating motion acceleration. The communication control unit 140 may cause the acceleration information to be transmitted to the one of the first communication unit 120 and the second communication unit 130 that has received the response information that is a response to the warning information.

The communication control unit 140 may cause the warning information to be transmitted based on the biological information and the acceleration information. Specifically, the determination unit 150 determines whether or not the acceleration information exceeds a predetermined allowable range. The communication control unit 140 transmits warning information when the determination unit 150 determines that the biological information exceeds the predetermined allowable range and the acceleration information does not exceed the predetermined allowable range. That is, the communication control unit 140 transmits warning information when the biological information indicates an abnormal state even though the user is hardly moving, and even if the biological information indicates an abnormal state, Warning information is not sent when the user is moving.

The determination unit 150 may determine whether the biological information is abnormal based on the biological information and the acceleration information. For example, when the determination unit 150 acquires the biological information, the change in the acquired biological information is determined based on the relationship between the acceleration detected by the acceleration detection unit 190 stored in advance in the storage medium and the amount of change in the biological information. It is determined whether or not it is caused by movement. The determination unit 150 determines that an abnormality has occurred in the biological information when the amount of change in the biological information exceeds the amount of change caused by the user's movement.

FIG. 9A shows an example of a front view of the biological information transmitting apparatus 100 having the acceleration detecting unit 190. FIG. 9B shows an example of a cross-sectional view taken along the line A-A ′ of the biological information transmitting apparatus 100 shown in FIG. 9A. The biometric information transmission device 100 includes a casing unit a that houses the biometric information acquisition unit 110, the first communication unit 120, the second communication unit 130, the communication control unit 140, and the determination unit 150. On the surface of the housing part a, an electrode 111 and an electrode 112 are provided for the biological information acquisition unit 110 to acquire information about the heartbeat. As shown in FIG. 9B, an acceleration detection unit 190 is embedded in the hard resin that constitutes the casing unit a.

The housing part a has a cavity for accommodating a printed circuit board on which the biological information acquisition unit 110, the first communication unit 120, the second communication unit 130, the communication control unit 140, and the determination unit 150 are mounted. The housing | casing part a is formed by injection-molding hard resin, for example using hard resin as a forming material.

10A and 10B are cross-sectional views of the periphery of the acceleration detection unit 190 embedded in the housing unit a. The acceleration detection unit 190 is provided in the housing unit a in a state sandwiched between a limiting member 191 and a limiting member 192 that limit the movement range of the acceleration detection unit 190. In the example of FIG. 10A, the acceleration detection unit 190 is embedded in the intermediate position in the thickness direction of the housing unit a in a state sandwiched between the limiting member 191 and the limiting member 192. In the example of FIG. 10B, the acceleration detection unit 190 is embedded in the outer position in the thickness direction of the housing unit a while being sandwiched between the limiting member 191 and the limiting member 192, and is protected further outside the limiting member 191. A member 193 is provided.

The forming material of the limiting member 191 and the limiting member 192 is preferably softer than the forming material of the housing portion a, and the forming material of the protective member 193 is preferably harder than the limiting member 191 and the limiting member 192. Furthermore, it is preferable that the expansion coefficient of the limiting member 191, the limiting member 192, and the protection member 193 is substantially the same as the expansion coefficient of the housing portion a. The forming material of the limiting member 191 and the limiting member 192 is, for example, silicone, rubber, or glass, and the forming material of the protective member 193 is, for example, glass or hard resin.

As described above, by embedding the acceleration detection unit 190 in the housing unit a, for example, it is not necessary to provide a dedicated housing for the acceleration detection unit 190 having a MEMS structure, and thus the biological information transmitting apparatus 100 can be reduced in size. . In addition, since the acceleration detection unit 190 is provided in the housing unit a with the restriction member 191 and the restriction member 192 interposed therebetween, an impact is applied to the acceleration detection unit 190 when the biological information transmitting apparatus 100 falls. The acceleration that occurs in the event of a failure is suppressed, and the acceleration detector 190 can be prevented from being destroyed.

Hereinafter, a method of embedding the acceleration detection unit 190 in the housing part a will be described. The acceleration detection unit 190 can be embedded in the casing a by integrally molding the acceleration detection unit 190 and the casing a using an insert molding method or an in-mold molding method.
First, the limiting member 191 and the limiting member 192 are bonded to both surfaces of the acceleration detection unit 190. Next, the acceleration detecting unit 190 in a state where the limiting member 191 and the limiting member 192 are bonded is mounted on a mold for molding the casing unit a. Subsequently, the forming material of the housing part a is injected into the mold. Since the acceleration detecting unit 190 is sandwiched between the limiting member 191 and the limiting member 192, the contraction force generated at the time of integral molding is relieved. Therefore, as shown in FIG. 10A, the acceleration detecting unit 190 and the casing unit a Can be integrally molded.

When the acceleration detection unit 190 is provided as shown in FIG. 10B, after the limiting member 191 and the limiting member 192 are bonded to both surfaces of the acceleration detection unit 190, the acceleration detection unit 190 is formed in a recess formed in the housing unit a in advance. Insert. The acceleration detection unit 190 can be fixed by adhering the protective member 193 to the housing part a after inserting the acceleration detection unit 190 into the recess.

In the example illustrated in FIG. 10A, the limiting member 191 and the limiting member 192 are in close contact with the acceleration detection unit 190. However, the biological information transmitting apparatus 100 includes the limiting member 191 and the limiting member 192 as illustrated in FIG. You may have a space between the acceleration detection part 190. FIG. In the example shown in FIG. 10C, the limiting member 191 and the limiting member 192 have, for example, a recess of about several tens of μm, and the acceleration detecting unit 190 is in a state where the limiting member 191 and the limiting member 192 are bonded to the acceleration detecting unit 190. Space is formed on both sides of the. Since the space is formed on both sides of the acceleration detection unit 190, the difference between the pressure inside the acceleration detection unit 190 and the pressure outside the acceleration detection unit 190 does not become too large. Therefore, the minute member that moves in accordance with the acceleration provided in the acceleration detection unit 190 can be prevented from moving due to the pressure difference, so that the acceleration measurement accuracy is improved.

FIG. 11B shows a BB ′ cross-sectional view of the biological information transmitting apparatus 100 shown in FIG. 11A. In the case part a of the biological information transmitting apparatus 100 according to the present embodiment, the direction of the surface of the predetermined area near at least one of the plurality of electrode parts changes. In the biological information transmitting apparatus 100 shown in FIGS. 11A and 11B, the housing part a is divided into a region a1, a region a2, a region a3, a region a4, and a region a5. The forming material of the housing part a in the regions a4 and a5 is softer and has a smaller coefficient of restitution than the forming material of the housing part a in other regions, for example.

The direction of the surface of the region a2 having the electrode 111 and the region a3 having the electrode 112 changes with respect to the direction of the surface of the region a1 according to the body shape of the person wearing the biological information transmitting apparatus 100. Specifically, as illustrated in FIG. 11B, the region a4 and the region a5 are flexible joints, and the region a2 connected to the region a1 through the region a4 by bending the region a4 and the region a5. The direction of the surface and the direction of the surface of the region a3 connected to the region a1 via the region a5 can be freely set within an angle (for example, within ± 20 °) within a predetermined range with respect to the direction of the surface of the region a1. Change. The direction of the region a2 and the direction of the region a3 can be different depending on the shape of the body part to which the biological information transmitting apparatus 100 is attached.

The biological information transmitting apparatus 100 shown in FIG. 11A further includes an electrode 113, and can measure an electrocardiogram by a plurality of induction methods including a first induction, a second induction, and a third induction. The biological information transmitting apparatus 100 further includes a switch 114. While the user of the biological information transmitting apparatus 100 is pressing the switch 114, the biological information acquisition unit 110 acquires biological information. When the user presses the switch 114, the region a4 and the region a5 in the housing part a are deformed and pressure is applied to the electrode 111, the electrode 112, and the electrode 113 on average to be in close contact with the human body. A heartbeat waveform or the like can be measured.

Is the same. Since the user of the biological information transmitting apparatus 100 can always attach the electrode 116 to the body, the biological information acquisition unit 110 can acquire a rapid change in the heartbeat waveform or the heart rate in real time.

The biological information transmitting apparatus 100 may automatically convert the guidance method between when the electrode 111, the electrode 112, and the electrode 113 are used and when the electrode 116 is used. For example, the biological information transmitting apparatus 100 measures an electrocardiogram by the first lead when the electrode 111, the electrode 112, and the electrode 113 are used, and measures a highly accurate electrocardiogram by the second lead when the electrode 116 is used.
