  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram illustrating the configuration of a respiratory data collection system 10, and as shown here, the respiratory data collection system 10 is attached to a face to collect and store respiratory data and a respiratory data collection device 20. And an analysis display device 70 for analyzing and displaying the respiration data by receiving the respiration data transfer from the respiration data collection device removed from the face after the collection of the respiration data.

  The breathing data collection device 20 is detachably attached to the skin corresponding to the top of the palate between the nostril 4 and the mouth 6 in the face 2, and separates nose breathing from the nostril 4 and mouth breathing from the mouth. It has the function to collect and memorize | store the respiration sensor which detects separately, and the detected respiration data, and to transmit to the analysis display apparatus 70. The respiratory data collection device 20 has a shape suitable for being applied to the face, and in that sense, the respiratory data collection device 20 can also be called an attachment pad having a data collection function. The analysis display device 70 has a function of analyzing and displaying respiration data received from the respiration data collection device 20 and a function of supplying power to the respiration data collection device 20.

  FIG. 2 is an exploded view for explaining elements constituting the respiratory data collection device 20. The respiration data collection device 20 includes a nasal respiration sensor 22 that detects nasal respiration, a mouth respiration sensor 24 that detects mouth respiration, a circuit board 26 on which circuit elements and the like are mounted, and the nostril 4 or mouth 6 of the face 2. And a metal plate 28 that can be deformed and can hold the deformed shape in order to adapt to the face shape in the vicinity of the skin, and adhere these to the face with a gel-like resin 50 having adhesiveness and waterproofness It is integrally formed into a pad shape that is easy to perform, and a portion of the gel-like resin 50 other than the inner surface side that contacts the face 2 is covered with a non-adhesive film 54. Detailed procedures such as integral molding will be described later.

  The nasal respiratory sensor 22 and the mouth respiratory sensor 24 are sensors for detecting the presence or absence of respiration using a pyroelectric polymer film. The pyroelectric polymer film is a polymer film having so-called pyroelectricity that outputs a voltage according to a temperature change and so-called piezoelectricity that outputs a voltage according to strain. Therefore, a voltage is generated by detecting the temperature change of the airflow and the pressure change of the airflow that occur according to the presence or absence of nasal breathing or mouth breathing. In order to output this voltage, electrode thin films are formed on both sides of the pyroelectric polymer film, and terminals are taken out from both electrode thin films, and connected to an appropriate detection circuit to detect the presence of nasal breathing or mouth breathing. Can be detected. Moreover, in order to protect from external environments, such as humidity, the whole is covered with a suitable protective film. As such a pyroelectric polymer film, for example, Kureha KF Piezo Film (trade name) can be used. In the example of the KF piezo film, a film having a total thickness including the electrode thin film layer of about 100 μm to a fraction of 1 mm can be used. FIG. 2 shows a state in which both electrode terminals 32 and 34 are drawn from the nasal breathing sensor 22 and both electrode terminals 36 and 38 are drawn from the mouth breathing sensor 24.

  The circuit board 26 is a board on which each element of the respiratory data collection device 20 is mounted. The circuit board 26 connects both the connection terminals 33 and 35 for connecting both electrode terminals 32 and 34 of the nasal breathing sensor 22 and the both electrode terminals 36 and 38 of the mouth breathing sensor 24 on a board having a wiring pattern. Optical data communication between the connection terminals 37 and 39, the rechargeable secondary battery 40, the power receiving coil section 42 that receives a high frequency signal for charging from the analysis display device 70, the control LSI 44, and the analysis display device. An LED 46 for carrying out, a reset switch 48 for carrying out resetting of the circuit system of the respiratory data collecting device 20, and the like are mounted. Although not shown in FIG. 2, ICs and electronic components are mounted on the circuit board 26 in addition to the control LSI 44. For example, the high-frequency signal received by the power receiving coil unit 42 is subjected to processing such as rectification and charged to the secondary battery, but these functions are executed by electronic components other than the control LSI 44.

  As a substrate having a wiring pattern for the circuit board 26, a double-sided or multilayer wiring glass epoxy substrate or the like can be used. As the secondary battery 40, for example, a small button type manganese lithium battery or the like can be used.

  The power receiving coil unit 42 is a coil having a function of receiving a high-frequency signal for charging a secondary battery transmitted from the analysis display device 70. FIG. 3 shows the structure of the power receiving coil section 42. The power receiving coil section 42 includes a coil 66 wound around a drum type ferrite having flanges 62 and 64 on both sides with an appropriate number of turns. The power receiving coil section 42 is not mounted on the surface of the circuit board 26 but is attached so that a hole is formed in the circuit board 26 and one end of the power receiving coil section 42 is exposed on the back side of the circuit board 26.

  Returning to FIG. 2 again, the control LSI 44 processes the detection signals from the nasal breathing sensor 22 and the mouth breathing sensor 24, converts them into nasal breathing presence / absence data and mouth breathing presence / absence data, and collects and stores the breathing data. This is an integrated circuit having a function. Some of these functions may be shared by other ICs or electronic components. The control LSI 44 may have a part of functions such as processing of a high-frequency signal received by the power receiving coil unit 42.

  The metal plate 28 is a thin plate having a substantially T-shaped planar shape, and is disposed on the back side of the circuit board 26, that is, on the side opposite to the side on which the control LSI 44 or the like is mounted, and is integrated with the circuit board 26 by a gel-like resin 50. It becomes. The material and thickness of the metal plate 28 can be easily shaped to follow the shape of the face when the pad-like breathing data collection device 20 integrated with the gel-like resin 50 is pressed against the face 2 with a finger or the like. It is selected as being deformable and capable of retaining the deformed shape. For example, a copper plate having a thickness of about 0.1 mm to 0.3 mm can be used. Further, the metal plate 28 may be connected to the ground terminal of the circuit board 26 so as to have a function of a shield plate against electrical noise from behind the circuit board 26.

  The LED 46 is a light emitting element that is connected to the data transmission function portion of the control LSI 44 and blinks in order to transmit the collected and stored respiratory data to the analysis display device 70 in accordance with a predetermined transmission protocol. This optical data transfer is executed when the respiratory data collection device 20 is removed from the face 2 after the collection of the respiratory data is completed. The LED 46 is connected to a data collection function part of the control LSI 44, and when the breathing data collection device 20 is attached to the face 2 and collecting breathing data, the breathing pitch is notified to inform the user of the breathing pitch. It is also used to execute a synchronous blinking function that blinks in synchronization with data detection. Switching between the data transfer function and the synchronous blinking function of the control LSI 44 can be performed by detecting that the deposition pad as the breathing data collection device 20 is removed from the face and mounted on the analysis display device 70.

  The reset switch 48 is a switch for performing an initial reset of the circuit system of the respiratory data collection device 20 and a forced reset at the time of abnormal operation. For example, each time the respiratory data collection device 20 is mounted on the analysis display device 70, the reset switch 48 can be operated to reset the circuit system by a reset circuit provided in the control LSI 44 or the like. As the reset switch 48, for example, a mechanical switch that controls on / off by a stroke of a detection pin, a pressure-sensitive switch that detects a pressing pressure, or the like can be used. In the case of using a mechanical switch, it is necessary to have a structure for detecting a stroke or pressing pressure in a state covered with a gel-like resin 50 in order to ensure waterproofness.

  The gel-like resin 50 is used to completely cover the circuit board 26 and each element mounted on the circuit board 26 and the metal plate 28, to shield from the outside, and to ensure waterproofness. Are integrally molded. In this case, the nasal respiration sensor 22 and the mouth respiration sensor 24 are configured to cover the portions of the electrode terminals 32, 34, 36, and 38, and portions for detecting respiration are left outside the gel-like resin 50. The outer shape after the integral molding is formed into a pad shape so that it can be easily attached to the face 2. The gel-like resin 50 is selected from materials having waterproofness and adhesiveness. As the gel-like resin 50, for example, a silicon resin can be used. It is desirable to add an appropriate antibacterial agent to the gel-like resin 50.

  The light guide 30 is provided at the upper position 52 of the LED 46 at the time of this integral molding, and has a function of emitting light from the LED 46 to the outside without passing through the gel-like resin 50. It is. The refractive index of the light guide 30 is preferably selected so that light from the LED 46 is totally reflected at the interface with the gel-like resin 50. In particular, when an antibacterial agent is added to the gel-like resin 50, the gel-like resin 50 becomes translucent or opaque. Therefore, the use of this light guide 30 allows the light from the LED 46 to be sent to the analysis display device 70. Effective for efficient transmission.

  The non-adhesive film 54 covers a portion other than the inner surface side in contact with the face 2 in the pad shape integrally formed with the gel-like resin 50, that is, a portion corresponding to the front side of the circuit board 26. It is a plastic film to eliminate stickiness. As the non-adhesive film 54, a silicon sheet having an appropriate thickness can be used. In order to attach the non-adhesive film 54 onto the pad shape integrated with the gel-like resin 50, the adhesiveness of the gel-like resin 50 can be used as it is. The side to which the non-adhesive film 54 is affixed is optical data transfer, transmission of a high frequency signal for charging, and resetting with the analysis display device 70, such as the LED 46 and the light guide 30, the power receiving coil section 42, and the reset switch 48. Since instructions are given, appropriate openings or locally thin portions may be provided so as not to impair their functions. In FIG. 2, openings are provided at the position 58 of the power receiving coil, the LED 46, and the position 56 of the light guide 30. Even if such an opening is provided in the non-adhesive film 54, the waterproof property of the respiratory data collection device 20 is ensured by the gel-like resin 50.

  FIG. 4 is a diagram illustrating a procedure for manufacturing the respiratory data collection device 20. Elements similar to those in FIG. 2 are denoted by the same reference numerals, and detailed description thereof is omitted. First, each element is mounted and mounted on the circuit board 26. Each element other than the power receiving coil section 42 can be mounted on the circuit board 26 using surface mounting technology. As described above, the power receiving coil portion 42 is positioned in the opening hole provided in the circuit board 26 and attached so that one end of the power receiving coil portion 42 is exposed to the back side of the circuit board 26. Next, the electrode terminals 32 and 34 of the nasal breathing sensor 22 and the electrode terminals 36 and 38 of the mouth breathing sensor 24 are connected to the connection terminals 33, 35, 37 and 39 of the circuit board 26, respectively. These connections are made under conditions that do not impair the performance of the pyroelectric polymer film. For example, a conductive adhesive tape or a conductive paste can be used. In some cases, soldering may be used. The state after being connected is shown in FIG.

  Next, the metal plate 28 is disposed on the back side of the circuit board 26, the light guide 30 is disposed on the LED 46, and the pad-shaped integral molding is performed with the gel-like resin 50. At this time, as described above, the respiration detection portions of the nasal respiration sensor 22 and the mouth respiration sensor 24 are exposed outside the gel-like resin 50. Further, the light guide 30 is disposed on the LED 46 and is molded so that the gel-like resin 50 does not come to that portion. The molding is performed using a molding die, and silicon gel to which an antibacterial agent is added is used as the gel-like resin 50. This is shown in FIG.

  Thereafter, the non-adhesive film 54 is affixed to a portion other than the inner surface side in contact with the face of the gel-like resin 50, that is, the side corresponding to the side on which the control LSI 44 of the circuit board 26 is mounted. In this way, the secondary battery 40, the power receiving coil section 42, the control LSI 44, the LED 46, the reset switch 48, the circuit board 26 on which these are mounted, the metal plate 28, and the like are incorporated, have a pad-shaped outer shape, and are waterproof. A small respiratory data collection device 20 is obtained which is covered with a natural gel-like resin 50 and has a sticky side on the face. This is shown in FIG.

  FIG. 5 is a cross-sectional view of the respiratory data collection device 20. As shown in FIG. 5, the respiratory data collection device 20 includes a control LSI 44, an LED 46, a circuit board 26, a metal plate 28, and the like inside a gel-like resin 50 and is configured to be shielded from the outside. Yes. The outer shape has a pad-like planar shape, and the thickness is about several mm. Further, most of the nasal breathing sensor 22 and the mouth breathing sensor 24 are exposed to the outside of the gel-like resin 50 and are brazed into appropriate shapes that can easily detect respiration. Of course, it is good also as a free shape. The respiratory data collection device 20 has a gel-like resin 50 as it is on one side in the thickness direction, and has waterproofness and adhesiveness. This surface is used as a side to be detachably attached to the face using adhesiveness. The opposite side is covered with a non-adhesive film 54, and this surface is used as the front side. The front side is the side that can be seen by the observer when the user's face is viewed in front, and is also the interface side on which optical data transfer, high-frequency signal transmission / reception, etc. are performed when stored in the analysis display device 70. .

  FIG. 6 is an enlarged cross-sectional view around the LED 46 and the light guide 30 of the respiratory data collection device 20. The light guide 30 is an optical component having a translucency as described above and having a function of totally reflecting light from the LED 46 at the interface with the gel-like resin 50 and guiding the light from the LED 46 to the outside. For example, it can be composed of a transparent plastic part having an appropriate refractive index. FIG. 6 shows an example in which the light guide 30 and the LED 46 are integrated and mounted on the circuit board 26. In this structure, for example, the LED 46 is disposed on the circuit board 26 by surface mounting technology, etc., and then a highly transparent resin is filled using an appropriate mold, molded by heating, and then the mold is removed. Can be obtained by the method. The mold may be left as it is. In that case, by using a mold made of a material having an appropriate refractive index, the light from the LED 46 is totally reflected on the inner surface of the mold, and the light guide property can be further improved. It is preferable that the gel-like resin 50 is not provided on the front side where light is emitted from the light guide 30, and that the non-adhesive film 54 is also provided with an opening. In addition, the unevenness | corrugation 31 provided in the outer periphery of the light guide 30 is for ensuring the waterproofness in the interface between the gel-like resin 50 enough. With this configuration, it is possible to efficiently radiate light from the LED 46 to the outside while ensuring waterproofness. Therefore, by transferring breathing data by blinking the LED 46, it is possible to ensure data waterproofing and to transfer data without using a contact type input / output port having an opening for data transfer.

  Next, the operation of the respiratory data collection device 20 having such a configuration will be described. When the user tries to collect respiration data, the respiration data collection device 20 is pressed against the skin corresponding to the palate portion of the user's face 2 as described in FIG. The shape of the metal plate 28 is made to follow the shape of the palate, and the shape is deformed. For example, during the user's sleep, the presence or absence of nasal breathing and the presence or absence of mouth breathing are detected by the nasal breathing sensor 22 and the mouth breathing sensor 24, and are collected and stored as breathing data by the function of the control LSI 44.

  The LED 46 can be blinked in synchronization with the respiration pitch detected by the nasal respiration sensor 22 and the mouth respiration sensor 24 in order to detect the respiration pitch when collecting respiration data. For example, breathing sound acquisition is performed every 100 msec, and a temporary threshold is used to determine whether or not there is provisional breathing compared to the breathing data acquired by the nasal breathing sensor 22 or the mouth breathing sensor 24. When the respiratory data exceeds the temporary threshold, it is determined that there is temporary breathing, and the LED 46 is turned on, and when the respiratory data is less than the temporary threshold, the LED is turned off. By doing in this way, LED46 repeats lighting and extinction according to the change of the respiration data acquired by the respiration sensor. That is, the LED 46 can be blinked in synchronization with the pitch corresponding to the breathing pitch. By blinking the LED 46 in synchronization with the breathing pitch, the user can know whether the pitch of nasal breathing or the like he is performing matches the breathing pitch detected by the breathing data collection device 20, and if not, The respiration pitch is detected again. In this way, the respiratory data of the respiratory data collection device 20 can be monitored. If the breathing pitch being performed by the user matches the breathing pitch detected by the breathing data collection device 20, for example, the monitoring can be terminated after a predetermined time has elapsed, and the blinking of the LED 46 can be terminated. In this way, the LED 46 can serve both as a function for detecting the breathing pitch when breathing data is collected and a function for data transfer. These functions can be switched by detecting whether or not the respiratory data collection device 20 is stored in the analysis display device 70.

  When the user wakes up from sleep, the breathing data collection device 20 is removed from the user's face 2, attached to the analysis display device 70, and the collected and stored breathing data is transferred.

The state where the upper housing 74 is attached to the lower housing 72 so as to be freely opened and closed is shown. The lid opening / closing switch 91 is a switch that is provided on the upper surface of the lower casing 72 and detects that the upper casing 74 is closed.

  On the right half of the lower housing 72 where the upper housing 74 is not disposed, a display LCD 90, a λ / MODE selection button 92, an UP-SELECT button 93, a DOWN-SELECT button 94 for selecting display contents of the display LCD 90, A time SET button 95 for time adjustment is provided. On the screen of the display LCD 90, the ratio between the edge breath and the breath is displayed as a pie chart. In the example of FIG. 7, the ratio of cuticle respiration is indicated by oblique lines, and about 75% is cuticle respiration and about 25% is hana respiration. These are respectively connected to a control unit not shown.

  A recess 76 provided in a portion of the lower housing 72 where the upper housing 74 opens and closes is for housing the respiratory data collection device 20. As described above, the respiratory data collection device 20 removed from the user's face is inserted into the recess 76 with the front side facing the bottom of the recess 76, and the upper housing 74 is moved relative to the lower housing 72. By closing, the analysis display device 70 is accommodated. Under this storage state, charging and data transfer are performed as described in detail below.

  The depression 76 is provided with a contactless signal interface with the respiratory data collection device 20.

  The light receiving sensor 78 is a sensor that detects a blinking signal of the LED 46 of the respiratory data collection device 20, and can be constituted by, for example, a photodiode or a phototransistor. The blinking signal of the LED 46 detected by the light receiving sensor 78 is transmitted to a control unit (not shown), is subjected to data processing, restored to breathing presence / absence data, analysis of apnea is performed, and the result is displayed on the display LCD 90. Is done. As described above, data transfer between the respiratory data collection device 20 and the analysis display device 70 is performed by contactless optical data transfer for detecting a blinking signal of the LED 46.

  The reset stroke 79 is used to cause the respiratory data collection device 20 to perform an initial reset and a forced reset. For example, when the respiratory data collection device 20 is housed when the stroke protrudes from the bottom surface of the recess 76, The tip of the reset stroke 79 may turn on the reset switch 48 of the respiratory data collection device 20. Whether the stroke of the reset stroke 79 is protruded or retracted from the recess 76 can be associated with, for example, ON / OFF of the lid opening / closing switch 91. That is, when the upper casing 74 is closed and the lid opening / closing switch 91 is turned on, the stroke is projected, and the reset switch 48 of the respiratory data collection device 20 is turned on. If the respiratory data collection device 20 is housed and the upper housing 74 is closed, the circuit system of the respiratory data collection device 20 can be reset without fail. Therefore, when the respiratory data collection device 20 is stored in the analysis display device 70 for the first time, an initial reset can be given to the respiratory data collection device 20, and if a situation that is considered to be a malfunction of the respiratory data collection device 20 occurs.

Here, as shown in FIG. 7, the U-shaped upper yoke 84 and the U-shaped lower yoke 82 are arranged at positions where the two U-shaped tip portions face each other. Further, one of the U-shaped tips of the lower yoke 82 is disposed on the bottom surface of the recess 76 of the lower housing 72. The tip of the lower yoke 82 disposed in the recess 76 is provided at a position corresponding to the drum-type ferrite flange 62 of the power receiving coil section 42 of the respiratory data collection device 20.

  Therefore, when the upper casing 74 is open with respect to the lower casing 72, the yoke of the transmission coil unit 80 is spatially separated, and even if a high frequency signal is supplied to the coil 86, it is generated thereby. The generated magnetic flux is only radiated over a wide area. When the respiratory data collection device 20 is housed in the recess 76 of the analysis display device 70 and the upper housing 74 is closed with respect to the lower housing 72, the state shown in FIG. That is, one of the U-shaped tips of the lower yoke 82 provided in the recess 76 and the corresponding one of the U-shaped tips of the upper yoke 84 receive power from the respiratory data collection device 20. The upper and lower flanges 62 and 64 of the drum-type ferrite of the coil portion 42 are in contact with and sandwiched therebetween. At the same time, the other U-shaped tip of the lower yoke 82 contacts the other U-shaped tip of the upper yoke 84 corresponding thereto.

  Therefore, when the magnetic circuit is closed with the lower yoke 82-the power receiving coil 42-the upper yoke 84-the lower yoke 82 and a high frequency signal is supplied to the coil 86 of the transmitting coil unit 80 in this state, a magnetic flux is applied to the magnetic circuit. The high frequency signal can be received from the coil 66 of the power receiving coil section 42 by the magnetic flux. As described above, when the breathing data collection device is housed and the openable casing is closed, the power receiving coil portion 42 of the breathing data collection device 20 is disposed between the upper yoke 84 and the lower yoke 82.

Here, for example, the voltage of the primary power supply 102 can be about 4.8V, the output of the DC / DC converter 108 can be 3V, and the output of the booster circuit 110 can be 5V.

  When the controller 100 detects that the respiratory data collection device 20 is housed in the analysis display device 70 and the upper housing 74 is closed by the lid opening / closing switch 91, the control unit 100 generates a command signal for boosting the output of the DC / DC converter 108. In addition to being supplied to the booster circuit 110, a high-frequency oscillation signal is supplied to the booster circuit 110, and the boosted high-frequency signal is supplied to the coil 86 of the transmission coil unit 80. At this time, as described with reference to FIG. 8, the upper yoke 84 and the lower yoke 82 of the transmission coil unit 80 and the power reception coil unit 42 of the respiratory data collection device 20 form a closed magnetic circuit.

In this way, contactless optical data transfer is performed between the respiratory data collection device 20 and the analysis display device 70. The amplified signal is transmitted to the control CPU 104, restored as respiration data, and necessary analysis is executed. The analysis result is displayed on the display LCD 90. The display content is changed by operating the λ / MODE selection button 92 or the like.
