Description

The present invention relates to a biological information acquisition device, and more particularly to a biological information acquisition device for a toilet.

The toilet space is a private room space at home, and even if it is installed in a public facility such as a commercial facility, it is a private room space divided into individual booths, so in any case, private space is generally secured. It is recognized as a relaxing space. On the other hand, since the toilet space is a place whose main purpose is to perform excretion, it is conceivable to use the same toilet space every day at home, at work, at school, and the like.

Therefore, the toilet space is the most suitable as a place to acquire the biometric information of the user for the purpose of grasping and managing the health condition of the user.

Here, in order to grasp the health condition, it is known that the blood pressure is measured while sitting on the toilet seat in the toilet space. Patent Document 1 discloses that a finger cuff for measuring blood pressure is provided on the upper surface of a toilet paper holder, and the blood pressure of the index finger inserted into the finger cuff is measured by a pressure sensor. Further, in Patent Document 2, a toilet accessory unit provided with a sphygmomanometer (pressure sensor) is provided at a position where blood pressure can be measured while sitting, and a user engages an index finger with a finger cuff provided on the toilet accessory unit. By doing so, it is disclosed to measure blood pressure.

However, in the above-mentioned method of measuring blood pressure with a pressure sensor while the finger is pressed, the configuration of the biological information acquisition device becomes complicated because the finger cuff is used, and the device becomes large, so that it is suitable as a commercial product. It wasn't a thing. In addition, since the fingers are tightened, the burden on the user is placed on the toilet seat.

Here, Patent Document 3 discloses that the surface of a fingertip is irradiated with light by a light emitting element, and the reflected light can be accurately measured by a pulse wave sensor that is received by the light receiving element. As described in Patent Document 3, a light emitting element and a light receiving element are housed in a measurement button provided in the first measurement having a measurement surface for placing the palm of the human body, and light is emitted only by placing a fingertip on the measurement button. Since the pulse wave waveform of the blood vessel at the fingertip can be detected by the element and the light receiving element, the measurement can be performed with a simple configuration without imposing a burden on the user.

However, since the sensor for detecting pulse wave information detects when it is touched, there is a risk that inaccurate biometric information may be detected by a fingertip that is unintentionally touched. In particular, from the viewpoint of user convenience, the risk increases when the sensor is arranged near the operation button of the toilet seat device.

In particular, the acquired biological information may not only be displayed on the spot by the user, but may also be stored and stored in a storage device. It is conceivable to notify the user or the like of the result of complex analysis of the past history of the user and other related information. However, if inaccurate biometric information is detected here, the inaccurate biometric information is also accumulated, resulting in a loss of reliability of the accumulated biometric information.

The present invention solves at least one of the above-mentioned problems, and provides a biometric information acquisition device that prevents or suppresses the collection of inaccurate biometric information in the biometric information acquisition device.

Therefore, one aspect of the invention disclosed in the present specification is a biometric information acquisition device provided in a toilet space, which is provided on a housing and the housing, and the biometric information is optically obtained by touching a fingertip. It has a biometric information acquisition unit for detection, a storage device for storing biometric information detected by the biometric information acquisition unit, and a control device for controlling the biometric information acquisition unit and the storage device, and the control device acquires biometric information. The biometric information acquisition device includes a standby mode in which the biometric information is not stored in the storage device after the unit detects the fingertip, and a measurement mode in which the biometric information is stored in the storage device.

The optical pulse wave sensor (biological information acquisition unit) can easily acquire biological information such as blood pressure by simply pressing the fingertip. However, since it detects when touched, there is a risk that inaccurate biological information may be detected by a fingertip that is touched unintentionally. In particular, from the viewpoint of user convenience, the risk increases when the sensor is arranged near the operation button of the toilet seat device.

In particular, the acquired biological information may not only be displayed on the spot by the user, but may also be stored and stored in a storage device. It is conceivable to notify the user or the like of the result of complex analysis of the past history of the user and other related information. However, if inaccurate biometric information is detected here, the inaccurate biometric information is also accumulated, resulting in a loss of reliability of the accumulated biometric information.

On the other hand, in one aspect of the present invention, in order to prevent inaccurate biometric information acquired by an unintentionally touched fingertip from being stored in the storage device, the biometric information acquisition device waits. The mode and the measurement mode were set. Here, in the standby mode, although the biological information acquisition unit performs optical detection, the acquired data is not stored in the storage device. On the other hand, in the measurement mode, the biological information acquisition unit performs optical detection, and the acquired data is stored in the storage device. As a result, when the fingertip touches the biological information acquisition unit during the standby mode, the measurement mode is unintentionally shifted to the measurement mode by satisfying a predetermined condition such that the contact continues for 1 second. It is possible to prevent the detected inaccurate biometric information from being stored in the storage device by the touched fingertip.

Further, if the biometric information acquisition unit of the biometric information acquisition device continues to detect in the standby mode, the amount of acquired information immediately exceeds the storage capacity of the storage device. Therefore, by not storing the information acquired in the standby mode, it is possible to avoid saturation of the storage capacity of the storage device due to the storage of unnecessary information.

Here, the "toilet space" in the present specification refers to at least a space equipped with a toilet bowl, which may be a space inside a general house, and is used in a public facility such as an office, a service area, or a commercial facility such as a leisure land. It may be a space. In addition, the toilet space in public facilities does not refer to the shared space where the dressing table and hand-washing table are placed, but to each private room booth equipped with a toilet bowl. On the other hand, in general houses and hotels, it also includes bathrooms with bathtubs in addition to toilet bowls. Although the toilet bowl is described in the present specification as mainly referring to a toilet bowl, it may be replaced with a urinal bowl as long as the object of the present invention is met.

Here, the "housing" in the present specification refers to a box body for forming the exterior of the biological information acquisition device according to the present invention and mounting functional components inside. The housing need not be composed of one component, and may be composed of a combination of a plurality of components, as long as it substantially functions to mount or include each functional component. Further, it is not necessary to form a closed internal space, and an opening or a gap may be provided.

Here, the "light emitting element" in the present specification is a functional component having a function of irradiating light having predetermined characteristics such as wavelength and intensity, and for example, an LED (light emitting diode) can be used. Further, the wavelength and intensity of the light to be irradiated can be appropriately selected as needed.

Here, the "light receiving element" in the present specification is a functional component having a function of receiving light having predetermined characteristics such as wavelength and intensity, and for example, a photodiode can be used. Further, the wavelength range of the received light can be appropriately selected so as to be suitable for the characteristics of the light emitting element to be used and the environment in which the biological information acquisition device is used.

Here, the "biological information" in the present specification is, in a narrow sense, optical information optically acquired from a user's fingertip by a biological information acquisition device, and in a broad sense, it is obtained by analyzing the optical information. Information about the health condition of the user. Further, the information is calculated and transferred via a computer, and is data that is processed such as addition of other information at any time.

Further, one aspect of the invention disclosed in the present specification is a biometric information acquisition device provided in a toilet space, which is provided in a housing and the housing, and the biometric information is optically obtained by touching a fingertip. It has a biometric information acquisition unit to be detected, a storage device for storing biometric information detected by the biometric information acquisition unit, and a control device for controlling the biometric information acquisition unit and the storage device, and the storage device is a first storage device. It has a device and a second storage device having a storage capacity larger than that of the first storage device, and the control device stores biometric information only in the first storage device after the biometric information acquisition unit detects a fingertip. It is a biological information acquisition device including a standby mode for storing biological information and a measurement mode for storing biological information in a second storage device.

The optical pulse wave sensor (biological information acquisition unit) can easily acquire biological information such as blood pressure by simply pressing the fingertip. However, since it detects when touched, there is a risk that inaccurate biological information may be detected by a fingertip that is touched unintentionally. In particular, from the viewpoint of user convenience, the risk increases when the sensor is arranged near the operation button of the toilet seat device.

In particular, the acquired biological information may not only be displayed on the spot by the user, but may also be stored and stored in a storage device. It is conceivable to notify the user or the like of the result of complex analysis of the past history of the user and other related information. However, if inaccurate biometric information is detected here, the inaccurate biometric information is also accumulated, resulting in a loss of reliability of the accumulated biometric information.

On the other hand, in one aspect of the present invention, in order to prevent inaccurate biometric information acquired by an unintentionally touched fingertip from being stored in the storage device, the biometric information acquisition device waits. The mode and the measurement mode were set. Here, in the standby mode, although the biological information acquisition unit performs optical detection, the acquired data is stored only in the first storage device. On the other hand, in the measurement mode, the biological information acquisition unit performs optical detection, and the acquired biological information is stored in the second storage device. As a result, when the fingertip touches the biological information acquisition unit during the standby mode, the measurement mode is unintentionally shifted to the measurement mode by satisfying a predetermined condition such that the contact continues for 1 second. It is possible to prevent the detected inaccurate biometric information from being stored in the second storage device by the touched fingertip.

Further, if the biometric information acquisition unit of the biometric information acquisition device continues to detect in the standby mode, the amount of acquired information immediately exceeds the storage capacity of the storage device. Therefore, a first storage device having a small storage capacity and a second storage device having a large storage capacity are prepared as storage devices, and the information acquired in the measurement mode requiring storage is stored in the second storage device. Therefore, it is possible to prevent the second storage device from saturate the storage capacity due to unnecessary information.

Further, the information stored in the first storage device may be sequentially deleted or overwritten during the execution period of the standby mode.

According to this aspect, after the determination process is performed using the first storage device having a small storage capacity, unnecessary information is not stored in the second storage device, and the living body deleted or later detected in the first storage device. By overwriting with information, it is possible to avoid saturation of the storage capacity of the first storage device.

Further, the first storage device and the second storage device may be provided in the housing.

According to this aspect, the processing can be executed independently inside the biometric information acquisition device without using another storage device.

According to the biometric information acquisition device of the present invention, there is provided a biometric information acquisition device that prevents or suppresses the collection of inaccurate data in the biometric information acquisition device.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. However, it is easily understood by those skilled in the art that the invention disclosed in the present specification is not limited to the following description, and its form and details can be changed in various ways. Further, the invention disclosed in the present specification is not construed as being limited to the description contents of the embodiments shown below. In order to facilitate understanding of the description, the same components are designated by the same reference numerals as possible in each drawing, and duplicate description is omitted.

(Embodiment 1)
In the present embodiment, the biological information acquisition device installed in the toilet space will be described with reference to FIGS. 1 to 5.

FIG. 1 is a perspective view illustrating an example of a remote control device 108 and a toilet seat device 101 equipped with the biological information acquisition device according to the embodiment of the present invention. The toilet seat device 101 illustrated in the present specification is mounted on the rim 105 of the toilet bowl 103, and includes a main body 106, a toilet seat 111, and a toilet lid 107. The main body 106 has a built-in electrical component, a water supply mechanism, and the like, and has a nozzle 104 capable of advancing to the bowl 102 of the toilet bowl 103 and injecting wash water toward a local part of the user. The toilet seat 111 on which the user sits during excretion is rotatably pivotally supported with respect to the main body 106. When the toilet seat 111 is not in use, it is covered from above by a toilet lid 107 that is also rotatably pivotally supported by the main body 106.

The remote control device 108 provided with a plurality of buttons for remotely controlling the toilet seat device 101, which is a device, is fixed to the wall surface of the toilet booth where the toilet bowl 103 and the toilet seat device 101 are installed. The remote control device 108 illustrated in the present specification is provided with its panel 109 facing the toilet seat device 101 side, and the user selects an operation to be performed by the toilet seat device 101 on the panel 109 and remotely controls the toilet seat device 101. .. Specifically, a communication device (not shown) provided in the remote control device 108 generates a high-frequency signal based on the content selected by the user on the panel 109 and wirelessly transmits it to the toilet seat device 101. The toilet seat device 101 receives this high-frequency signal in a communication device (not shown) built in the main body 106, and based on the content of the signal, discharges or stops water from the nozzle 104, adjusts the water force of the discharged water, and nozzles. The position of 104 can be changed.

Here, the biological information acquisition device according to the present embodiment is mounted on the remote controller device 108 in the embodiment of FIG. The biological information acquisition device 110 shown in FIG. 1 is provided on the upper right side of the remote controller device 108 when viewed from the front. By mounting the biological information acquisition device 110 at such a position, when the user is seated on the toilet seat 111, the user can easily bring the right fingertip into contact with the biological information acquisition device 110 without any load. In FIG. 1, since the remote control device 108 is located on the right side when the user is seated, the biological information acquisition device 110 in the remote control device 108 is mounted at the above position, but the remote control device 108 is the user. If the biometric information acquisition device 110 in the remote controller 108 is provided on the left side when the user is seated, the biometric information acquisition device 110 is mounted at a reasonable position under the seated state of the user, such as by providing the biometric information acquisition device 110 on the upper left side. It is good to do.

In the present embodiment, the biological information acquisition device 110 is mounted on the remote controller device 108, but the present invention is not limited to this. The biological information acquisition device 110 may be any device in the toilet space, and is particularly preferably arranged at a position within reach of the user while sitting on the toilet seat. For example, in addition to a remote controller, it can be mounted on a paper roll, a handrail, a towel rack, a towel shelf, a mirror, a water faucet for hand washing, a dressing table, a storage shelf (storage cabinet), and the like. Further, the biometric information acquisition device 110 may be directly attached to the wall surface or door of the toilet room instead of the device in the toilet space.

FIG. 2 is a perspective view illustrating a remote controller device equipped with the biological information acquisition device according to the embodiment of the present invention. As shown in FIG. 2, the remote controller device 108 may be provided with a plurality of operation switches 120. The plurality of operation switches 120 include, for example, operation switches 120a to 120g. When the operation switch 120 is operated (pressed in this example), the remote control device 108 transmits a control signal corresponding to the operated switch. When the main body 106 of the toilet seat device 101 receives the control signal, the main body 106 operates or changes the function setting based on the control signal.

The remote control device 108 has a mode for the user of the toilet bowl 103 to operate the function of the toilet seat device 101. In this mode, the remote control device 108 operates the setting and operation of the toilet seat device 101 displayed on each operation switch 120. In the example of FIG. 2, the main body 106 stops the local cleaning function, the sound generation function, and the warm air drying function when the operation switch 120a is pressed, and starts the buttocks cleaning when the operation switch 120b is pressed. When the operation switch 120c is pressed, the bidet cleaning is started, when the operation switch 120d is pressed, sound generation is started, when the operation switch 120e is pressed, ventilation is started, and when the operation switch 120f is pressed, a sound is generated. The volume of the vocal function is changed, and when the operation switch 120 g is pressed, the water force of the local cleaning function is changed.

The remote controller 108 further enters the setting mode from the above-mentioned normal use mode by a special operation. The special operation is an operation in which a plurality of operation switches 12 are combined and pressed, or an operation in which the operation switch 12 is pressed a plurality of times. The special operation may include simultaneous pressing or long pressing of the operation switch.

In the setting mode, each operation switch 120 is assigned a function different from the mode in normal use. That is, in the setting mode, the remote controller 108 performs operation control and function setting change of the main body 106 different from the normal mode based on the pressing of the operation switch 120. For example, in the setting mode, the temperature of the washing water ejected from the nozzle 104 and the temperature of the toilet seat 111 can be set.

Further, the main body 106 can perform "nozzle cleaning" by a special operation of the remote controller 108 in the setting mode. "Nozzle cleaning" is an operation in which the nozzle 128 is in a state of advancing into the bowl portion of the toilet bowl 111 without injecting washing water for a certain period of time. As a result, the administrator can wipe the outside of the nozzle 104 with a cloth or the like, or clean the spout of the nozzle 104.

Further, the remote control device 108 is equipped with a biological information acquisition device 110. The biological information acquisition device 110 includes a functional unit for acquiring biological information inside the housing 122 as described later. Further, the outer surface of the housing 122 of the biometric information acquisition device 110 is provided with a biometric information acquisition region for acquiring biometric information by pressing a part of a user's finger. In particular, in the biometric information acquisition device 110 illustrated in FIG. 2, the biometric information acquisition region substantially coincides with the surface on which the cover member 121 is provided. That is, in the biological information acquisition device 110 illustrated in FIG. 2, the user presses a part of the finger against the cover member 121, and the pulse wave is detected from the part of the finger pressed by the user. , Biological information is acquired.

Further, on the front surface of the remote controller 108, the operation switches 120h for starting the acquisition of biometric information are provided in the plurality of operation switches 120 described above. The user can acquire biological information such as a pulse wave by pressing down the operation switch 120h at a predetermined timing or an arbitrary timing. Although the operation switch 120h is arranged in the remote controller device 108 in FIG. 2, it may be provided on the outer surface of the housing 122 of the biological information acquisition device 110. In this case, since the functions can be integrated with the biological information acquisition device 110, the functions of the remote controller device 108 and the biological information acquisition device 110 can be separated, and the internal structure can be simplified. Further, the operation switch 120h for starting the acquisition of biological information can be omitted. That is, by executing the control to start the acquisition of the biometric information when the fingertip of the user is detected in the biometric information acquisition area, the operation for starting the acquisition of the biometric information by the user can be omitted. , Convenience for the user can be improved.

The remote controller 108 and the biometric information acquisition device 110 may share a housing, or may be a combination of different parts each having a different housing. In the latter case, if either the remote controller 108 or the biological information acquisition device 110 is damaged or malfunctions, the device can be easily restored by performing maintenance or replacement on one of them.

FIG. 16 is a block diagram of a remote controller device and a toilet seat device equipped with the biological information acquisition device according to the embodiment of the present invention.

The first storage device 153 stores the biometric information of the user acquired by the biometric information acquisition device 110 and the operation information of the user for the plurality of operation switches 120.

The second storage device 154 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory (Flash Memory), or a storage device such as a hard disk (magnetic disk) or an optical disk. The second storage device 154 stores, for example, a program for controlling the operation of the toilet bowl cleaning function 157, the local cleaning function 158, and the warm air drying function 159. Further, the second storage device 154 outputs the biometric information of the user acquired by the biometric information acquisition device 110, the toilet bowl cleaning operation signal output when the toilet bowl cleaning function 157 is executed, and the execution of the local cleaning function 158. The local cleaning operation signal to be performed, the warm air drying operation signal output with the execution of the warm air drying function 159, and the seating detection signal output from the seating detection device 160 are also stored. Therefore, it is preferable that the second storage device 154 has a larger storage capacity than the first storage device 153.

Further, since the first storage device 153 and the second storage device 154 are both provided in the remote controller device 108, for example, a storage device provided in a toilet seat device 101, which is another device in the toilet, can be used. It is possible to execute the process independently inside the remote controller device 108.

The notification device 155 is realized, for example, by a speaker that outputs voice or a display screen that outputs an image. The notification device 155 is, for example, the biological information acquired by the biological information acquisition unit 135 and stored in the first storage device 153 or the second storage device 154, or the biological information acquired by the biological information acquisition unit 135.

The control device 156 executes arithmetic processing based on the programs stored in the first storage device 153 and the second storage device 154 by the functions of processors such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit). It is a device. Further, the control device 156 can also be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

Next, the configuration included in the toilet seat device 101 will be described. As shown in FIG. 16, the toilet seat device 101 includes a communication device 152, a control device 156, a toilet bowl cleaning function 157, a local cleaning function 158, a warm air drying function 158, and a seating detection device 160. Here, since the communication device 152 and the control device 156 have the same configuration as the remote control device 108, the description thereof will be omitted.

The toilet bowl cleaning function 157 is a function of supplying cleaning water to the bowl portion 102 included in the toilet bowl 103. The toilet bowl cleaning function 157 includes a water supply channel and a water supply valve (not shown) in order to realize the function. This water supply channel is a passage leading to the bowl portion 102 in order to supply washing water such as tap water to the bowl portion 102. Further, the water supply valve is composed of an electromagnetic valve or the like and is provided at a predetermined position in the water supply channel. The toilet bowl cleaning function 157 opens the water supply channel to start supplying the cleaning water to the bowl portion 102 based on the control signal transmitted from the remote control device 108, and shuts off the water supply channel after a lapse of a predetermined time to make the bowl. The supply of wash water to the unit 102 is stopped. The toilet bowl cleaning function 157 supplies wash water to the bowl portion 102, and discharges stool and urine in the bowl portion 102 to the drainage channel together with the wash water staying in the bowl portion 102. Further, the toilet bowl cleaning function 157 outputs a toilet bowl cleaning operation signal to the control device 156 while the water supply valve is open.

The local cleaning function 158 is a function of injecting cleaning water toward the local part of the user with the nozzle 104 advanced into the bowl portion 102. The local cleaning function 158 includes a nozzle hole (not shown) and a nozzle drive motor in order to realize the function. The nozzle holes are formed on the upper surface of the nozzle 104, and are provided at a plurality of different positions, for example, for cleaning the buttocks and cleaning the bidet. The nozzle drive motor drives the advance / retreat of the nozzle 104 through the opening formed in the main body 106 based on the control signal from the remote control device 108. The local cleaning function 158 outputs a local cleaning operation signal to the control device 156 while the cleaning water is ejected from the nozzle.

The warm air drying function 159 is a function of blowing air into the bowl portion 102 of the toilet bowl 103. The hot air drying function 159 warms the sucked outside air with a heater based on the control signal from the remote control device 108, and blows warm air from the air outlet toward the inside of the bowl portion 102. The warm air drying function 159 outputs a warm air drying operation signal to the control device 156 while blowing warm air from the air outlet.

The seating detection device 160 detects a state in which the user is seated on the toilet seat 111. The seating detection device 160 is realized by, for example, a load sensor or an infrared light emitting / receiving type ranging sensor, and may detect a human body existing in the vicinity of the toilet seat 111 immediately before the user sits on the toilet seat 111. The seating detection device 160 outputs a seating detection signal to the control device 156.

Next, the biological information acquisition device 110 according to this embodiment will be described with reference to FIGS. 3 to 8.

Further, the light receiving element 131 functions as a photodetector, and a photodiode, a photoresistor, a CCD (Charge-Coupled Device: charge-coupled device), a photomultiplier tube, or the like can be used. In particular, photodiodes are preferable because they have high accuracy in measuring light intensity.

Further, the light emitting element 130 and the light receiving element 131 are provided on the base 133, and the base 133 is arranged on the bottom surface of the recess of the housing 122.

Here, the base 133 has a function as a substrate for fixing the light emitting element 130 and the light receiving element 131. Further, if the base 133 is used as a circuit board (printed circuit board) and electrical connections are made in the base 133, the biological information acquisition unit 135 can be miniaturized.

In FIG. 3, the light emitting element 130 and the light receiving element 131 are provided on the upper part of the base 133, but the present invention is not limited to this embodiment, and both or one of the light emitting element 130 and the light receiving element 131 may be embedded in the base 133. Alternatively, it may be provided so as to penetrate the base 133. In this case, since the thickness in the height direction can be made thin, the biological information acquisition device 110 can be made thin.

Further, the light emitting element 130 and the light receiving element 131 may be arranged directly on the bottom surface of the recess of the housing 122 without using the base 133. By omitting the base 133, the thickness in the height direction can be made thin, so that the biological information acquisition device 110 can be made thin.

Further, although the light emitting element 130 and the light receiving element 131 are described as different members in FIG. 3, if a so-called one-chip type configuration in which both are formed on one semiconductor substrate, the biological information acquisition region 134 is further expanded. It can be miniaturized.

Further, the cover member 121 provided above the light emitting element 130 and the light receiving element 131 allows the light emitted from the light emitting element 130 to pass to the outside of the cover member (outside the biological information acquisition device 110). Since it is necessary to allow light incident from the outside of the cover member 121 to pass so as to reach the light receiving element 131, it is provided with translucency. Therefore, here, the cover member 121 functions as a window through which light passes as described above. As shown in FIG. 4, the user can detect optical biometric information through the window by pressing a part of the finger against the outer surface of the cover member 121. The portion through which light can pass is the biological information acquisition region 134.

In FIG. 3, the light emitting element 130 and the light receiving element 131 are arranged on the bottom surface of the housing via the base 133, but the present invention is not limited to this, and for example, the light emitting element 130 and the light receiving element 131 may be arranged on the back surface side of the cover member 121. By using the cover member 121 as a glass substrate and forming the light emitting element 130 and the light receiving element 131 on the glass substrate by using a known semiconductor manufacturing process, the biological information acquisition unit can be made thin.

FIG. 5 is a top view of the biological information acquisition unit 135. In the biological information acquisition device 110 illustrated in FIG. 5, a rectangular recess is formed in the housing 122 when viewed from above, and the light emitting element 130 and the light receiving element 131 are arranged side by side inside the recess. Further, a rectangular cover member 121 is provided so as to cover the recess.

By providing the biometric information acquisition unit 135 as described above, the biometric information of the user can be optically acquired from the fingertips of the user. The acquisition of biological information by the biological information acquisition unit 135 in the biological information acquisition device 110 according to the embodiment of the present invention will be described with reference to FIG.

FIG. 4A illustrates a case where the finger pad from the DIP joint (first joint) toward the fingertip of the user's finger is pressed against the biometric information acquisition region 134 of the biometric information acquisition device 110 for measurement. is there. In this way, when the biometric information is acquired from the finger pad from the DIP joint (first joint) to the fingertip on the finger, the measurement can be performed by the pressing motion that follows the motion of the user pointing. , There is less burden on the user to press the fingertips. In this case, the light emitted from the light emitting element 130 passes through the cover member 121 and reaches the finger pad portion of the user pressed against the cover member 121. For example, when an LED is used as the light emitting element 130, the near-infrared light emitted from the LED is absorbed by hemoglobin in the blood, so that the reflected light reflects the change in the absorbance of the blood. The light receiving element 131 detects the reflected light via the cover member 121, so that the biometric information of the user can be acquired.

Acquisition of biometric information from the user's fingers is not limited to the above method. For example, as shown in FIG. 4B, the biometric information of the user is obtained by pressing the finger pad portion between the PIP joint (second joint) and the MP joint (third joint) of the fingers against the cover member 121. You may get it. In this way, when information is acquired at the finger pad between the PIP joint (second joint) and the MP joint (third joint) of the finger, a wide measurement area can be secured even in the finger. Since the contact area is wide, stable measurement can be performed.

Here, when the biological information acquisition unit 135 has a structure as shown in FIG. 3, it is necessary to always press the user's fingers against the cover member 121, so that sweat or sebum is applied to the surface of the cover member 121. Or, dirt on the fingers will adhere. In that case, the translucency of the cover member 121 is lowered, and the emission of light from the light emitting element 130 and the light reception to the light receiving element 131 are hindered, so that the detection accuracy of biological information may be lowered.

Therefore, by making the cover member 121 removable, it is possible to easily prevent a decrease in the detection accuracy of biological information by cleaning the removed cover member 121 or replacing it with another clean cover member 121. it can.

On the other hand, when the cover member 121 has a replaceable structure, a slight gap may occur between the cover member 121 and the housing 122 depending on the design. Then, there is a possibility that water may enter the inside of the recess by wiping with water at the time of cleaning. Therefore, the cover member 121 is configured so as not to be removable, and a sealing member is used to form a sealed structure so that moisture entering into parts for acquiring biological information such as the light emitting element 130 and the light receiving element 131 does not adhere. You can also.

That is, as shown in FIG. 3, it is preferable to arrange the seal 132 around the base 133 provided with the light emitting element 130 and the light receiving element 131. As the sealing material, for example, a rubber material that achieves sealing by crushing an O-ring or the like can be used. The seal 132 shown in FIG. 3 is arranged in an annular shape so as to completely surround the base 133 including the light emitting element 130 and the light receiving element 131, the lower end thereof is in contact with the bottom surface of the recess of the housing 122, and the upper end thereof is in contact with the bottom surface of the recess. It is provided in contact with the cover member 121. That is, by completely sealing the space including the base 133 with the cover member 121, the housing 122, and the seal 132, the intrusion of moisture, contaminants, etc. into the space is suppressed, and the light emitting element 130 and the light receiving element are suppressed. It is possible to prevent deterioration and damage of 131 and these electrical connections.

It is possible to protect the light emitting element 130, the light receiving element 131, and the like from water entering from 142.

In FIG. 6, the configuration is illustrated in which the user's fingers do not directly touch the cover member 121, but the present invention is not limited to this. For example, FIG. 7 shows an embodiment in which openings 141 are provided above the light emitting elements 130 and the light receiving elements 131, which are arranged side by side in a top view (that is, there are two openings) (FIG. 7 (FIG. 7). a) shows a cross-sectional view, and FIG. 7B shows a plan view viewed from above).

In FIG. 7A, the area of the opening 141 is smaller than the contact surface when the user presses a part of the fingertip. As a result, it is possible to prevent the user's fingers from entering the internal space provided with the light emitting element 130 and the light receiving element 131. Further, as shown in FIG. 7A, the cover member 121 can be provided in the internal space of the housing below the opening 141. With this configuration, the fingertips of the user do not come into direct contact with the cover member 121, so that dirt such as sweat and sebum adhering to the fingertips can be prevented from adhering to the cover member 121, and the opening is opened by dust or cleaning. It is possible to protect the light emitting element 130, the light receiving element 131, and the like from water entering from 141.

Further, for example, FIG. 8 shows a mode in which a plurality of openings 140 are provided above the light emitting element 130 and the light receiving element 131 arranged side by side in a top view (FIG. 8A is a cross-sectional view and a view). 8 (b) shows a plan view viewed from above). That is, in the biological information acquisition region 134, the housing 122 is formed in a mesh shape (mesh shape) in the top view.

In FIG. 8A, the area of the plurality of openings 140 is smaller than the contact surface when the user presses a part of the fingertip. As a result, it is possible to prevent the user's fingers from entering the internal space provided with the light emitting element 130 and the light receiving element 131. Since the housing 122 located between the plurality of openings 140 is made of a material for passing light, it is preferable that the width t2 of the housing 122 is smaller than the width t1 of the openings 140.

Further, as shown in FIG. 8A, the cover member 121 can be provided in the internal space of the housing 122 below the opening 141. With this configuration, the fingertips of the user do not come into direct contact with the cover member 121, so that dirt such as sweat and sebum adhering to the fingertips can be prevented from adhering to the cover member 121, and a plurality of stains such as dust and cleaning can be prevented. It is possible to protect the light emitting element 130, the light receiving element 131, and the like from water entering through the opening 140.

In the present embodiment, in the biological information acquisition device installed in the toilet space, a case where the biological information acquisition area is arranged toward the lower side of the toilet space will be described with reference to FIGS. 9 to 14. As for other configurations, the configurations described in the first and second embodiments can be appropriately used.

FIG. 9 is a perspective view showing a remote controller 200 including the biological information acquisition device 210 according to the present embodiment. In FIG. 9, the biological information acquisition device 210 is provided at the lower left end of the front surface of the remote controller device 200.

FIG. 10 is a perspective view of the remote controller device 200 of FIG. 9 as viewed from the lower surface side. A cover member 203 is provided on the left side of the housing 202 on the lower surface of the remote controller 200. Although not shown, as described in the first embodiment, the light emitting element and the light receiving element are arranged at positions corresponding to the cover member 203 inside the housing 202, so that the biometric information of the user can be acquired. There is.

Here, as shown in FIG. 11, the user acquires biometric information by pressing a finger from below the remote controller device 200 against the cover member 203 (biological information acquisition area 204) provided on the lower surface of the remote controller device 200. Can be done. On the other hand, since the biological information acquisition area 204 is provided on the lower surface of the remote control device 200, the light emitted from the lighting equipment provided on the ceiling or above the wall surface of the toilet space is blocked by the remote control device 200. It is possible to reduce or prevent direct entry into the biological information acquisition area 204.

In the present embodiment, the installation position of the biological information acquisition area is not limited to the lower surface of the remote controller 200. For example, as shown in FIG. 12, the cave 205 can be provided below the front surface of the housing 202 of the remote controller 200, and the biological information acquisition region 206 can be provided on the upper surface inside the cave 205. As shown in FIG. 13, the user can acquire the biometric information of the user by touching the biometric information acquisition region 206 inside the sinus 205 with a finger. According to this embodiment, the structure of the cave 205 can block the light irradiation from the surroundings, particularly the lighting fixtures installed above.

As a mode in which the cave 205 is provided in the housing 202 of the remote controller 200, the biological information acquisition region 206 is the upper surface of the cave 205 in FIG. 13, but if it is inside the cave 205, it is provided on the lower surface or the side surface. You can also. The structure of the cave 205 can block light irradiation from the surroundings, especially the lighting fixtures installed above.

In this embodiment, the biological information acquisition region is arranged at a position where it is as difficult as possible for external light to enter in order to prevent the intrusion of external light. However, on the other hand, there may be a problem that it becomes difficult for the user to see the installation position of the biological information acquisition area. Therefore, it is advisable to provide a guide on the remote controller or the biological information acquisition device to indicate the position of the biological information acquisition area to the user.

For example, in FIG. 14A, a plate 207 indicating the position is attached in order to indicate the biometric information acquisition area arranged in a hidden position for the user. The plate may be a seal that is easy to remove. Further, the location of the biological information acquisition area may be written in words on the plate 207, or a symbol, a picture, a photograph or the like having a meaning of touching a finger may be written on the plate 207. Further, as shown in FIG. 14 (b), a protruding structure may be provided in a part of the housing so as to clearly indicate that it is a portion to which a finger is placed for measurement.

(Embodiment 4)
Next, in the present embodiment, the biological information acquisition region in the biological information acquisition device of the present invention will be described with reference to FIG.

FIG. 15 is a diagram illustrating a biological information acquisition device 300 integrated by incorporating a biological information acquisition device into a remote control device that operates a toilet seat device in a toilet space. The biological information device 300 illustrated in FIG. 15 has a horizontally long box shape, and a plurality of operation switches 302 are arranged on the front surface. On the other hand, in the lower right, a biometric information acquisition region 303 (detection region) is provided for the user to acquire biometric information by pressing his / her fingertip.

Here, the biological information acquisition region 303 may have a structure in which a cover member is provided on the surface as described in the first embodiment, and as described in the second embodiment, the outside of the housing provided with a plurality of openings. It may be composed of a surface.

In particular, the area of the biological information acquisition area 303 is preferably larger than the area of the operation switch 302. By making the area of the biological information acquisition area 303 larger than the area of the operation switch 302, the distinguishability of the detection area is improved, and the user can easily find the position. In particular, the area of the biological information acquisition area 303 may be 1.2 times or more and 2 times or less the area of the operation switch 302. If it is doubled or more, the distinctiveness of the biometric information acquisition area 303 is improved, but problems such as an increase in the size and design of the biometric information acquisition unit or a decrease in convenience due to the dwarfing of the operation switch occur. ..

Since the area of the biological information acquisition area 303 and the operation switch 302 has a problem of distinctiveness, it is sufficient to calculate the area in the plane measured in the front view, and even if the operation switch 302 has a three-dimensional structure, it is a plane. You can compare by the area when projected on.

In particular, in order to enhance the distinguishability of the biological information acquisition region 303, it is preferable to design the area of the biological information acquisition region 303 to be wider than the area of all the operation switches 302 arranged in front of the biological information acquisition device 300.

Further, in order to enhance the distinctiveness of the biological information acquisition area 303, instead of expanding the area of the biological information acquisition area 303, for example, a lighting device (for example, LED) that irradiates visible light is arranged around the biological information acquisition area 303. However, the lighting fixture can be turned on and blinked.

Further, the biological information acquisition area 303 may be arranged on the biological information acquisition device 300 so as to be closest to the user when the user sits on the toilet seat. In particular, when the user reaches out and tries to touch the biological information acquisition device 300, the biological information acquisition area 303 may be arranged at the position where the distance is the shortest. As a result, it is possible to acquire biometric information without forcing the user to take an unreasonable posture.

Further, when the user is seated on the toilet seat, the other operation switch 302 is not arranged on the flow line in which the user tries to reach out and touch the biometric information acquisition area 303 on the biometric information acquisition device 300. Design it. As a result, it is possible to prevent malfunction due to the user accidentally pressing another operation switch 302.

(Embodiment 5)
Next, in the present embodiment, the control method of the biological information acquisition device according to the present invention will be described with reference to FIG. FIG. 17 is a flowchart showing an example of a procedure for processing the biological information acquired by the biological information acquisition device 400 according to the embodiment of the present invention.

In the example of FIG. 17, the biological information acquisition device 400 detects the fingertip of the user (step S11). For example, the biological information acquisition device 400 detects the fingertip of the user based on the amount of change in the light received by the light receiving element provided in the biological information acquisition device 400 per unit time.

When the biological information acquisition device 400 detects the fingertip of the user (step S11: Yes), the biological information acquisition device 400 acquires biological information from the light reflected by a part of the user's finger (step S12), and obtains the acquired biological information. It is stored in the storage device 402 of 1 (step S13).

As shown in FIG. 17, the biological information acquisition device 400 determines whether or not a predetermined time has elapsed after detecting the fingertip of the user (step S11: Yes). (Step S14). In other words, it is determined whether the fingertip of the user unintentionally touches the biometric information acquisition area or whether the user intentionally tries to acquire the biometric information. Therefore, the biometric information acquisition device 400 according to the present embodiment acquires biometric information (step S12) and acquires the biometric information until a predetermined time elapses (step S14: No) in the state of detecting the fingertip of the user. A standby mode is executed in which the stored biological information stored in the first storage device 402 (step S13) is repeated. In this way, the predetermined time is set to exclude the detection caused by the user unintentionally touching the biometric information acquisition area, for example, a period of 1 second or more and less than 5 seconds. It is good to set.

The biometric information acquired in the standby mode is not used when the acquired biometric information is subsequently notified to the user. Therefore, it is preferable to sequentially delete or overwrite each time new biometric information is stored in the first storage unit 402. This makes it possible to avoid saturation of the storage capacity of the first storage device 402 due to storage of unnecessary information.

Then, when it is determined that the predetermined time has elapsed in the state of detecting the fingertip of the user (step S14: Yes), the measurement mode is executed until the fingertip of the user is no longer detected (step S18: No).

In the measurement mode, biometric information is acquired from the light reflected by a part of the user's finger (step S15), and the acquired biometric information is stored in the second storage device 404 (step S17).
The biological information stored in the second storage device 404 is not only used for the purpose of notifying the user on the spot, but also complex with the past history of the user and other related information. It is also used for the purpose of performing various analyzes. Therefore, in order to identify the state of the biometric information acquired by the user, information on the execution of the functions of the toilet seat device 406 such as the toilet bowl cleaning function, the local cleaning function, and the warm air drying function is added. Is preferably stored (step S16). This makes it possible to estimate in what state the user has acquired the biometric information, and can determine the reliability of the acquired biometric information.

In addition, the individual user may be identified (individual authentication) by referring to the data provided in advance from the acquired biometric information. Thereby, the information about the user can be associated with the obtained biological information.

After the user's fingertip is no longer detected (step S18: yes), the biometric information acquisition device 400 provides information on the biometric information stored in the second storage device 404 in which the function of the toilet seat device 406 is executed. Is added or not (step S19).

Here, when the information that the function of the toilet seat device 406 is executed is not added to the biometric information stored in the second storage device 404 (step S19: Yes), it is stored in the second storage device 404. The biometric information is transmitted to the notification device 408 and notified to the user (step S20). Here, the biological information to be notified to the user may be only the biological information acquired this time by the biological information acquisition device 400, and a complex analysis is performed together with the past history and other related information. It does not matter if it is the result of the damage.

Further, when the information that the function of the toilet seat device 406 is executed is added to the biological information stored in the second storage device 404 (step S19: No), the accuracy of the acquired biological information becomes low. There is a possibility that Therefore, the biometric information stored in the second storage device 404 is not notified to the user. Alternatively, the biometric information stored in the second storage device 404 is transmitted to the notification device 408 together with the fact that the accuracy of the information is low, and is notified to the user (step S21). As a result, it is possible to prevent a decrease in the reliability of the information notified from the notification device 408, or to give attention to the handling of the information notified from the notification device 408.

It has been described that the measurement mode for acquiring biometric information is executed during the period from step S15 to step 18 in which the fingertip is detected, but the measurement mode is not limited to this, and the measurement mode is changed, for example, with the passage of a predetermined time. You may end it. In this case, in order to notify the user of the end of the measurement mode, it is advisable to notify the image display, sound, or the like.

Further, during the period of the measurement mode from step 15 to step 18, it is preferable to output a comfortable voice or music to the user from the sound output device provided separately. As a result, the user tends to be in a psychologically stable state, and stable acquisition of biological information is promoted. Further, in order to stabilize the psychological state of the user, not only the auditory information but also the visual information comfortable to the user may be output alone or at the same time as the sound from a separately provided image output device.

(Embodiment 6)
Next, in the present embodiment, the control method of the biological information acquisition device according to the present invention will be described with reference to FIG. FIG. 18 is a flowchart showing an example of a procedure for processing the biological information acquired by the biological information acquisition device 500 according to the embodiment of the present invention.

In the example of FIG. 18, in the biological information acquisition device 500, the operation switch (for example, the operation switch 120h in FIG. 2) provided in the remote controller device 502 or the like for starting the acquisition of biological information is pushed down by the user. Is detected (step S31). Then, after the pressing operation of the operation switch is detected, the audio guide by the notification device 504 or the biological information acquisition unit 506 is provided so as to put a finger on the biological information acquisition area included in the biological information acquisition device 500. The blinking of the light source is started (step S32). As a result, it is possible to suppress the possibility that the fingertip of the user unintentionally touches the biological information acquisition area.

After that, when the biological information acquisition device 500 does not detect the fingertip of the user (step S33: No), the standby mode is started. If the fingertip of the user is not detected for a predetermined period after the start of this standby mode, the notification device 504 notifies the user of an error (step S35). In the standby mode, the information acquired by the biological information acquisition unit 506 is not stored in the storage device because it is not information based on the light reflected by a part of the user's finger.

Further, the biometric information obtained by touching the biometric information acquisition unit 506 with the fingertip of the user during the standby mode can be used for analysis as data for identifying the user (personal authentication). Further, based on the analysis result, it may be decided whether or not to shift to the measurement mode.

On the other hand, when the biometric information acquisition device 500 detects the fingertip of the user (step S33: Yes), the voice guidance by the notification device 504 or the blinking of the light source provided in the biometric information acquisition unit 506 is stopped (step S33: Yes). S36), the measurement mode for acquiring biological information from the light reflected by a part of the user's finger is started.

As shown in FIG. 18, whether or not the state of detecting the fingertip of the user (the period during which the biometric information can be acquired) has elapsed for a predetermined period after the biometric information acquisition device 500 starts the measurement mode. Is determined (step S40). In other words, it is determined whether the state in which the user's fingertip is touching the biometric information acquisition area is the state in which the biometric information is acquired in a stationary state in which highly reliable biometric information can be acquired. As described above, the predetermined period is set to detect that the user is touching the biometric information acquisition area in a stationary state, and for example, a period of 5 seconds or more may be set. The control executed in the measurement mode and the control after the end of the measurement mode will be omitted because they are the same as those in FIG.

Further, during the period of the standby mode from step 33 to step 34, or during the period of the measurement mode from step 37 to step 40, it is preferable to output comfortable voice or music to the user from the sound output device provided separately. As a result, the user tends to be in a psychologically stable state, and stable acquisition of biological information is promoted. Further, in order to stabilize the psychological state of the user, not only the auditory information but also the visual information comfortable to the user may be output alone or at the same time as the sound from a separately provided image output device. In particular, by carrying out these in the standby mode, it is possible to achieve a psychologically stable state before the measurement of the user's biological information.

This embodiment can be implemented in combination with other embodiments as appropriate.

The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited thereto, and various modifications can be made based on the technical idea of the present invention.
