[0052] (The process that led to this invention)

[0053] In the moisture meter described in Patent Document 1, a moisture detection unit (sensor unit) located at the end of a swinging member that swings relative to the main body can be brought into contact with a measurement area inside the oral cavity to measure the moisture content in the oral cavity. Furthermore, in the moisture meter described in Patent Document 1, the sensor unit and the swinging member are configured as detachable parts (oral appliance) that can be attached to and detached from the main body. This maintains the hygienic condition of the meter in a more suitable state.

[0054] In such devices, the sensor unit is covered by an insulator or similar material, thus the sensor unit contacts the measurement area through the insulator. Consequently, the sensitivity of the sensor unit decreases due to the insulator, making it difficult to improve the detection accuracy. For this reason, efforts are made to improve the detection accuracy of the sensor unit.

[0055] Furthermore, efforts are being made to improve the energy irradiation efficiency in oral appliances equipped with energy irradiation units that irradiate heat, light, or other energy into the oral cavity.

[0056] Therefore, the inventors studied how to solve the above-mentioned problem by focusing on the thickness of the insulating layer covering the functional part, which includes at least one of the sensor part and the energy irradiation part, and came up with the following invention.

[0057] One aspect of the present invention is a sheet-shaped oral appliance detachably mounted to a main oral device, comprising: a functional part having at least one of one or more sensor parts for acquiring information within the oral cavity and one or more energy irradiation parts for irradiating energy within the oral cavity; a connecting part having an electrical connection part; and a wiring part having wiring that connects the one or more sensor parts and at least one of the one or more energy irradiation parts to the electrical connection part. The functional part, the connecting part, and the wiring part are each composed of at least a wiring layer and a plurality of insulating layers. The wiring layer has a first main surface and a second main surface opposite to the first main surface. The plurality of insulating layers have a first insulating layer disposed on the first main surface of the wiring layer and a second insulating layer disposed on the second main surface of the wiring layer. In the functional part, the thickness of the first insulating layer is less than the thickness of the second insulating layer.

[0058] With this structure, performance can be improved in oral appliances that can be detachably installed in the main body of the oral cavity.

[0059] Alternatively, the above-mentioned wiring layer and the above-mentioned multiple insulating layers can be stacked together.

[0060] This structure allows for easy insertion of oral instruments into the mouth.

[0061] Alternatively, the thickness of the wiring section may be greater than the thickness of the aforementioned functional section.

[0062] This structure can improve the mechanical strength of the wiring section.

[0063] Alternatively, the wiring section may have one or more shielding layers disposed on the aforementioned multiple insulating layers.

[0064] With this structure, noise generated from the wiring section can be suppressed.

[0065] Alternatively, the wiring section may have a protective layer disposed on the outer periphery of the wiring section.

[0066] This structure can suppress malfunctions caused by contact between oral appliances and the user's teeth when used in the oral cavity.

[0067] Alternatively, one or more of the sensor units may have a sensor surface for acquiring information about the measurement site in the oral cavity, and the sensor surface may be disposed on the first main surface side of the wiring layer.

[0068] This structure can improve the detection accuracy of one or more sensor units.

[0069] Alternatively, one or more energy irradiation units may be disposed on the first main surface side of the wiring layer.

[0070] This structure can improve the irradiation efficiency of the energy irradiation unit.

[0071] Alternatively, the aforementioned functional parts may be flexible.

[0072] With this structure, the functional part can be easily brought into contact with the measuring or irradiated area.

[0073] Alternatively, in the aforementioned functional unit, one or more openings are provided in the first insulating layer, and at least one of the one or more sensor units and the one or more energy irradiation units is disposed in the area exposed from the one or more openings.

[0074] This structure allows for greater improvement in the performance of dental appliances.

[0075] Alternatively, within one or more openings, two or more adjacent sensor units among the plurality of sensor units may be spatially separated.

[0076] This structure allows for greater improvement in the performance of dental appliances.

[0077] Alternatively, the oral appliance may also include a correction sensor unit, which is located at a different position from the one or more sensor units, and acquires correction information for correcting the information acquired by the one or more sensor units.

[0078] Based on this structure, correction information can be obtained to correct information acquired by one or more sensor units.

[0079] Alternatively, the aforementioned correction sensor may be disposed in at least one of the aforementioned wiring portion and the aforementioned connection portion in the aforementioned wiring layer.

[0080] Based on this structure, information from outside the oral cavity can be acquired as corrective information.

[0081] Alternatively, the aforementioned modified sensor unit may be configured to be arranged side-by-side with one or more sensor units along the wiring layer of the aforementioned functional unit and to acquire intraoral information with a different detection sensitivity than the one or more sensor units.

[0082] Based on this structure, corrective information can be obtained from information within the oral cavity.

[0083] Alternatively, the electrical connection portion may be one or more electrodes exposed from at least one of the first insulating layer and the second insulating layer.

[0084] This structure allows for easy electrical connection between the oral appliance and the main oral device.

[0085] Alternatively, the aforementioned electrical connection part can be an RFID tag.

[0086] This structure allows for easy electrical connection between the oral appliance and the main oral device.

[0087] Alternatively, the oral appliance may be configured as a bag-shaped structure in which the first main surface of the wiring layer is arranged facing outward and the second main surface of the wiring layer is arranged facing inward.

[0088] This structure allows for a more secure fixation of oral appliances to the main oral device.

[0089] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Furthermore, the following description is merely illustrative and is not intended to limit the scope of this disclosure, its applications, or its uses. Also, the drawings are schematic, and the proportions of the dimensions may not necessarily correspond to reality.

[0090] (Implementation Method 1)

[0091] [Dental devices]

[0092] Figure 1 and Figure 2 This is a schematic perspective view of an example of an oral device 1A according to Embodiment 1 of the present invention.Figure 1 This indicates that the oral appliance 10 is installed on the main oral device 50. Figure 2 This indicates the state where the dental appliance 10 has been removed from the main dental device 50. The X, Y, and Z directions in the figure represent the length, width, and height of the dental device 1A, respectively.

[0093] like Figure 1 and Figure 2 As shown, the oral device 1A includes an oral appliance 10 and an oral main body 50. The oral device 1A is a disposable device. In the oral device 1A, the oral appliance 10 used inside the oral cavity is detachably mounted relative to the oral main body 50. After being used by the oral appliance 10 mounted on the oral main body 50, it is removed from the oral main body 50.

[0094] The oral device 1A performs functions by bringing the oral instrument 10 into contact with a part of the oral cavity. These functions may include, for example, sensing and / or energy irradiation.

[0095] The sensing and detection function acquires information associated with biological information within the oral cavity. Biological information refers to various physiological and anatomical information produced by an organism. Examples of biological information include dryness (moisture content), tongue pressure, biting force, chewing function, swallowing function, tongue and lip movement function, poor hygiene, saliva composition, exhaled gas composition, body temperature, and hardness. Information associated with biological information includes, for example, electrostatic capacitance, impedance (resistance), pressure, potential, hue, temperature, hardness, and vibration. The oral device 1A brings the oral appliance 10 into contact with a measurement site within the user's oral cavity, acquiring information associated with the biological information of the contacted measurement site. Based on the information acquired by the oral appliance 10, the oral device 1A acquires biological information from the main oral device 50, thereby measuring the state within the oral cavity. The main oral device 50 measures, for example, moisture content, saliva secretion, biting force, tongue pressure, tongue hue, and / or the amount of various substances contained in saliva.

[0096] The energy irradiation function irradiates energy within the oral cavity. This energy can be, for example, light, heat, ultrasound, or electromagnetic waves.

[0097] The oral device 1A can be used, for example, as a hygrometer, bite force meter, tongue pressure gauge, laser therapy device, thermotherapy device, ultrasonic echo, ultrasonic therapy device, and electromagnetic irradiator.

[0098] In Embodiment 1, an example of an oral device 1A being a hygrometer will be described.

[0099] Figure 3 This is a schematic diagram illustrating an example of the state of using the oral device 1A according to Embodiment 1 of the present invention.Figure 3 As shown, the oral device 1A brings the oral instrument 10 into contact with a measurement site inside the user's mouth. The measurement site may be, for example, the tongue, buccal mucosa, or palate inside the mouth. The oral instrument 10 comes into contact with the measurement site by deforming along its shape. The oral device 1A begins measurement with the oral instrument 10 in contact with the measurement site inside the mouth.

[0100] [Dental appliances]

[0101] Figure 4 This is a schematic diagram showing an example of an oral appliance 10. Figure 5 It is Figure 4 A schematic cross-sectional view of an example of an oral appliance 10, shown in an enlarged form. Figure 6 This is a block diagram showing the structure of an example of an oral appliance 10.

[0102] like Figures 4-6 As shown, the oral appliance 10 includes a functional part 20, a wiring part 30, and a connecting part 40.

[0103] In Embodiment 1, the oral appliance 10 is configured as a sensor detector that can be detached from and attached to the main oral appliance 50. The oral appliance 10 is a sheet-shaped appliance with an electrical connection. The oral appliance 10 is formed as a rectangular sheet in the longitudinal direction. However, the oral appliance 10 can be formed as a sheet and is not limited to a rectangular shape.

[0104] The electrical connection is electrically connected to the main body device 50 for oral cavity use. In Embodiment 1, the electrical connection is one or more electrodes 41.

[0105] The oral appliance 10 is flexible and deformable. In the oral appliance 10, at least the functional part 20 is flexible.

[0106] <Functional Department>

[0107] The functional unit 20 performs sensing and detection functions and is located at the end of the oral appliance 10. The functional unit 20 includes a sensor unit 21 for acquiring information within the oral cavity. The sensor unit 21 has a sensor surface 21a disposed at a measurement site within the user's oral cavity. The functional unit 20 acquires information within the oral cavity by contacting the sensor surface 21a of the sensor unit 21 with the measurement site surface. In Embodiment 1, the sensor unit 21 includes an electrostatic capacitance sensor to acquire electrostatic capacitance.

[0108] When the functional unit 20 comes into contact with the measurement site in the oral cavity, it can deform along the shape of the measurement site. This allows the functional unit 20 to easily contact the measurement site in the oral cavity. Specifically, by deforming the functional unit 20 along the shape of the measurement site, the sensor surface 21a of the sensor unit 21 mates with the shape of the measurement site. This allows the entire sensor surface 21a to be positioned close to the measurement site, thus enabling easy acquisition of information from the measurement site using the entire sensor surface 21a.

[0109] In Embodiment 1, an example of the functional part 20 being flexible is described, but it is not limited to this. In the oral appliance 10, at least the functional part 20 needs to be flexible. For example, the wiring part 30 and / or the connecting part 40 may also be flexible.

[0110] <Wiring Department>

[0111] The wiring section 30 is disposed between the functional section 20 and the connecting section 40. The wiring section 30 has wiring 31 that electrically connects the electrodes 41 of the functional section 20 and the connecting section 40. The wiring 31 is formed of a conductive material. Examples of conductive materials for the wiring 31 include Cu, Al, and Ag. For example, the wiring 31 is formed of a wiring conductor pattern.

[0112] Furthermore, the wiring section 30 has a protective layer 32 covering its perimeter. The protective layer 32 is disposed on the portion of the oral appliance 10 that comes into contact with the teeth when placed in the oral cavity. The protective layer 32 can be disposed between the functional section 20 and the connecting section 40. For example, the protective layer 32 is formed of a protective film with a thickness of 100 μm or more and 10 mm or less. The protective film is formed, for example, from a resin, foam, or other similar material.

[0113] <Connecting Part>

[0114] The connecting portion 40 is a part installed on the main body device 50 of the oral cavity, and is located on the rear end side opposite to the end of the oral appliance 10. The connecting portion 40 has one or more electrodes 41. In Embodiment 1, the connecting portion 40 has two electrodes 41. In addition, the number of electrodes 41 is not limited to two.

[0115] One or more electrodes 41 are formed of a conductive material. Examples of materials for electrodes 41 include Cu, Al, and SUS. Furthermore, electrodes 41 can also be formed of materials that are not easily corroded, such as Au, Ag, silver chloride, Ti, Pt, carbon, and conductive polymers (e.g., PEDOT). Electrodes 41 can also be formed of Cu and plated with Au, Ni, or the like.

[0116] In Embodiment 1, if the connecting part 40 is installed on the oral cavity main body device 50, the plurality of electrodes 41 and the plurality of connecting terminals provided on the oral cavity main body device 50 are electrically connected by physical contact.

[0117] Furthermore, a mounting hole 42 is provided in the connecting portion 40. The mounting hole 42 is a through hole into which the protrusion 73a of the disassembly and assembly operation portion 70, described later, is inserted. In Embodiment 1, two mounting holes 42 are provided in the connecting portion 40.

[0118] Furthermore, the mounting hole 42 is not limited to a through hole; it can also be a notch or a recess. The mounting hole 42 only needs to be large enough to allow the protrusion 73a of the disassembly / removal operation part 70 to be inserted. In addition, one or more mounting holes 42 can be provided on the connecting part 40.

[0119] like Figure 5 As shown, the oral appliance 10 is composed of a wiring layer 11 and multiple insulating layers 12 and 13. In Embodiment 1, the wiring layer 11 and the multiple insulating layers 12 and 13 are stacked. Furthermore, the multiple insulating layers 12 and 13 have a first insulating layer 12 and a second insulating layer 13.

[0120] <Wiring Layer>

[0121] The wiring layer 11 includes a sensor unit 21, wiring 31, and a plurality of electrodes 41. The wiring layer 11 has a first main surface PS1 and a second main surface PS2 opposite to the first main surface PS1. In the oral appliance 10, the side with the first main surface PS1 is the side that contacts the measurement site inside the oral cavity. In Embodiment 1, the sensor surface 21a of the sensor unit 21 is disposed on the side with the first main surface PS1 of the wiring layer 11.

[0122] On the first main surface PS1 side of the wiring layer 11, a plurality of electrodes 41 are exposed from the first insulating layer 12. Alternatively, the plurality of electrodes 41 may be exposed from at least one of the first insulating layer 12 and the second insulating layer 13.

[0123] Preferably, the thickness of the wiring layer 11 is 1 μm or more and 50 μm or less. More preferably, the thickness of the wiring layer 11 is 2 μm or more and 25 μm or less.

[0124] <Multiple Insulation Layers>

[0125] The plurality of insulating layers 12, 13 have: a first insulating layer 12 disposed on the first main surface PS1 of the wiring layer 11 and a second insulating layer 13 disposed on the second main surface PS2 of the wiring layer 11.

[0126] The thickness T1 of the first insulating layer 12 is less than the thickness T2 of the second insulating layer 13. The thickness T1 of the first insulating layer 12 is less than or equal to half the thickness T2 of the second insulating layer 13. Preferably, the thickness T11 of the first insulating layer 12A in the functional unit 20E is less than or equal to one-eighth the thickness T12 of the second insulating layer 13. Preferably, the thickness T1 of the first insulating layer 12 is 0.01 μm or more and 25 μm or less. Preferably, the thickness T2 of the second insulating layer 13 is 10 μm or more and 200 μm or less. Furthermore, the thickness T1 of the first insulating layer 12 refers to the thickness of the first insulating layer 12 located on the outer side of the first main surface PS1 of the wiring layer 11 in the Z direction. The thickness T2 of the second insulating layer 13 refers to the thickness of the second insulating layer 13 located on the outer side of the second main surface PS2 of the wiring layer 11 in the Z direction.

[0127] In Embodiment 1, an example is described in which the thickness T1 of the first insulating layer 12 is less than the thickness T2 of the second insulating layer 13, which extends throughout the functional part 20, the wiring part 30, and the connecting part 40, but this is not a limitation. At least in the functional part 20, the thickness T1 of the first insulating layer 12 is less than the thickness T2 of the second insulating layer 13.

[0128] In the functional unit 20, the thickness T1 of the first insulating layer 12 is less than the thickness T2 of the second insulating layer 13. This improves the detection accuracy of the sensor unit 21 on the side of the first main surface PS1 of the wiring layer 11. Specifically, by reducing the thickness T1 of the first insulating layer 12, the influence of the first insulating layer 12 on the information acquisition of the sensor unit 21 is reduced. More specifically, by reducing the thickness T1 of the first insulating layer 12, the distance between the sensor surface 21a of the sensor unit 21 and the measurement area is reduced. This makes information acquisition from the sensor surface 21a easier, improving the detection accuracy of the sensor unit 21. Thus, by making the thickness T1 of the first insulating layer 12 smaller than the thickness T2 of the second insulating layer 13, the functional unit 20 is protected, and the detection accuracy of the sensor unit 21 is improved. Furthermore, by making the thickness T1 of the first insulating layer 12 smaller than the thickness T2 of the second insulating layer 13, information acquisition from the first main surface PS1 side is easier compared to the second main surface side. Alternatively, the detection direction of the oral appliance 10 can be limited to the first main surface PS1 side by designing the thickness T2 of the second insulating layer 13 to a thickness that cannot be detected by the sensor unit 21.

[0129] Multiple insulating layers 12 and 13 are formed of insulating materials. Examples of insulating materials include polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), nylon, polyvinyl chloride, and polyimide.

[0130] For example, wiring layer 11 and multiple insulating layers 12, 13 are formed from a flexible printed circuit board.

[0131] Furthermore, the oral appliance 10 described above is just one example, and its structure is not limited to this. The oral appliance 10 can be a sheet-like appliance with an electrical connection portion. Alternatively, the oral appliance 10 may also have a shielding layer in addition to the wiring layer 11 and multiple insulating layers 12, 13. Multiple insulating layers may also include two or more insulating layers.

Figure 9 This is a block diagram illustrating the structure of an example of a dental main body device 50. Furthermore, hereinafter, the dental main body device 50 will sometimes be referred to as the main body device 50.

[0134] like Figures 7-9 As shown, the main device 50 includes a main body 60, a disassembly / assembly operation section 70, a protective section 80, and a display section 90. Furthermore, in Embodiment 1, an example of the main device 50 including the protective section 80 and the display section 90 is described, but it is not a limitation. The protective section 80 and the display section 90 are not essential structures. For example, the display section 90 may be included in other devices different from the main device 50.

[0135] The main unit 50 can be detachably mounted on the oral instrument 10 via the disassembly / assembly operation section 70. Furthermore, the main unit 50 calculates the amount of the object to be measured based on information associated with biological information acquired by the oral instrument 10. Specifically, the main unit 50 calculates the water content (humidity) based on the electrostatic capacitance acquired by the oral instrument 10.

[0136] <Main Body>

[0137] The main body 60 is the main part of the main body device 50. The main body 60 is formed of a rod-shaped member having a length direction. The main body 60 has a gripping part 61 for the user to hold. The gripping part 61 is formed by the external shape of the main body 60.

[0138] A disassembly / removal operation section 70 is provided at one end of the main body 60. A protective section 80 and a display section 90 are provided on the main body 60.

[0139] The main body 60 includes a control unit 62 and a computing unit 63.

[0140] The control unit 62 is a structural element constituting the overall control of the dental device 1A. The control unit 62 includes, for example, a memory storing a program and processing circuitry corresponding to a processor such as a CPU (Central Processing Unit). For example, in the control unit 62, the processor executes the program stored in the memory.

[0141] The control unit 62 controls the calculation unit 63 and the display unit 90.

[0142] The calculation unit 63 calculates the amount of the object to be measured based on the information obtained from the oral instrument 10. In Embodiment 1, the calculation unit 63 calculates the water content based on the electrostatic capacitance obtained from the oral instrument 10.

[0143] The computing unit 63 can be implemented using semiconductor components or the like. The functions of the computing unit 63 can be implemented solely by hardware, or by combining hardware and software.

[0144] In Embodiment 1, the calculation unit 63 includes a moisture content calculation circuit. The moisture content calculation circuit calculates the moisture content based on the electrostatic capacitance obtained from the oral appliance 10 and the relationship between electrostatic capacitance and moisture content.

[0145] The information on the water content calculated by the calculation unit 63 is sent to the display unit 90.

[0146] <Disassembly and Assembly Operation Section>

[0147] The disassembly / assembly operation unit 70 is configured to detachably mount the oral appliance 10 relative to the main body 60 by applying and releasing a force relative to the oral appliance 10. In Embodiment 1, the disassembly / assembly operation unit 70 is configured to detachably mount the oral appliance 10 in a direction intersecting the extending direction of the main body 60. That is, the disassembly / assembly direction of the oral appliance 10 is a direction intersecting the extending direction of the main body 60.

[0148] The disassembly / assembly operation unit 70 has an electrical connection conductor. This electrical connection conductor is electrically connected to the dental appliance 10. Specifically, the electrical connection conductor is electrically connected to the electrical connection portion of the dental appliance 10. In Embodiment 1, the electrical connection conductor is one or more connection terminals 71. These one or more connection terminals 71 are formed of a conductive material. The one or more connection terminals 71 are electrically connected to one or more electrodes 41 disposed on the connection portion 40 of the dental appliance 10 through physical contact.

[0149] The disassembly / assembly unit 70 secures and installs the oral appliance 10 while the electrode 41 is electrically connected to the connecting terminal 71 by applying force to the connecting portion 40. Furthermore, the disassembly / assembly unit 70 releases the force applied to the connecting portion 40 of the oral appliance 10 to remove the appliance 10. Additionally, the electrical connection between the electrode 41 and the connecting terminal 71 can be disconnected when the oral appliance 10 is removed.

[0150] The disassembly / assembly operation unit 70 includes: a mounting surface 72 for mounting the oral appliance 10; and a pressing member 73 that applies force in a direction intersecting the mounting surface 72. In Embodiment 1, the pressing member 73 is positioned above the mounting surface 72.

[0151] The mounting surface 72 is provided on one end face of the main body 60. The mounting surface 72 is a surface that allows the oral appliance 10 to slide. The mounting surface 72 can be formed by the end face of one end of the main body 60 being concave, or it can be formed by a flat surface.

[0152] One or more connection terminals 71 are provided on the mounting surface 72. These connection terminals 71 are positioned corresponding to one or more electrodes 41 when the oral appliance 10 is mounted on and fixed to the mounting surface 72. In Embodiment 1, two connection terminals 71 are provided on the mounting surface 72. However, the number of connection terminals 71 is not limited to two.

[0153] A positioning member 72a extending toward the pressing member 73 is provided on the mounting surface 72. The positioning member 72a determines the position in the X direction on the mounting surface 72. The positioning member 72a may be formed, for example, by a step formed on the mounting surface 72, or it may be formed by protruding from the mounting surface 72 toward the pressing member 73. For example, when the oral appliance 10 is slidably moved in the X direction and positioned on the mounting surface 72, the oral appliance 10 is slidably moved until the end of the connecting portion 40 of the oral appliance 10 contacts the positioning member 72a. In this way, when the oral appliance 10 is installed on the disassembly and assembly operation part 70, the oral appliance 10 is slidably moved until it contacts the positioning member 72a, thereby making it easy to determine the position of the oral appliance 10 in the X direction. As a result, the installation of the electrode 41 of the oral appliance 10 at the position where it is physically in contact with the connecting terminal 71 disposed on the mounting surface 72 becomes easier, and electrical connection can be easily made.

[0154] The pressing member 73 is a member capable of applying and releasing force relative to the oral appliance 10. The pressing member 73 is configured to apply force in a direction intersecting the mounting surface 72. Thus, the pressing member 73 can fix the oral appliance 10 to the mounting surface 72 while the electrode 41 is electrically connected to the connecting terminal 71.

[0155] The pressing member 73 is formed of a plate-shaped member having one end E1 and the other end E2. One end E1 is located on the side of the mounting surface 72. The other end E2 is located on the side opposite to one end E1. A rotation axis 74 is disposed between one end E1 and the other end E2 of the pressing member 73. The pressing member 73 is configured to be able to rotate about the rotation axis 74. Furthermore, one end E1 of the pressing member 73 is subjected to force, for example, by an elastic body in a direction close to the mounting surface 72. Examples of elastic bodies include springs and rubber.

[0156] The pressing member 73 has a protrusion 73a that protrudes towards the mounting surface 72 between one end E1 and the rotation shaft 74. The protrusion 73a is inserted into the mounting hole 42 provided in the connecting portion 40 of the oral appliance 10. In Embodiment 1, the pressing member 73 has two protrusions 73a provided at one end E1 of the pressing member 73. Alternatively, the pressing member 73 may have only one or more protrusions 73a.

[0157] In the disassembly and assembly operation unit 70, the application and release of force relative to the oral appliance 10 are operated by rotating the pressing member 73. Specifically, when the pressing member 73 is not operated, one end E1 of the pressing member 73 moves towards the mounting surface 72 due to the force of the elastic body, pressing the oral appliance 10 mounted on the mounting surface 72. As a result, the oral appliance 10 is fixed by being clamped between the mounting surface 72 and the pressing member 73, and the oral appliance 10 can be installed in the disassembly and assembly operation unit 70. Furthermore, by inserting the protrusion 73a of the pressing member 73 into the mounting hole 42 of the connecting part 40, the oral appliance 10 can be fixed without detaching from the disassembly and assembly operation unit 70.

[0158] When removing the oral appliance 10 from the disassembly / removal operation section 70, press down on the other end E2 of the pressing member 73, thereby moving one end E1 of the pressing member 73 away from the placement surface 72. This releases the pressure exerted on the oral appliance 10 by the pressing member 73, allowing the oral appliance 10 to be removed from the disassembly / removal operation section 70. Thus, the oral appliance 10 can be removed by operating the disassembly / removal operation section 70, allowing for easy removal without contact with the used oral appliance 10.

[0159] Furthermore, in Embodiment 1, an example of the pressing member 73 being forced by an elastic body was described, but this is not a limitation. The pressing member 73 may also be forced in a direction intersecting the placement surface 72 by a mechanism other than an elastic body, such as a locking mechanism, a sliding mechanism, and / or electromagnetic force. In addition, a suction part may be provided to apply force to the oral appliance 10 by suction.

[0160] <Protection Department>

[0161] The protective part 80 is disposed on the main body 60 and protects the grip part 61. The protective part 80 prevents saliva from adhering to the user's hand when using the oral device 1A and holding the grip part 61.

[0162] In Embodiment 1, the protective part 80 is disposed on the main body 60 on the side where the oral appliance 10 is installed. The side where the oral appliance 10 is installed refers to the side where the oral appliance 10 is installed and removed. Furthermore, the protective part 80 is formed of a plate-shaped component.

[0163] <Display Section>

[0164] The display unit 90 is disposed on the main body 60 and displays information of the dental device 1A. The information of the dental device 1A includes, for example, information about the subject of the measurement.

[0165] In Embodiment 1, the information of the object being measured is the moisture content. For example, the calculation unit 63 calculates the moisture content based on the electrostatic capacitance obtained from the oral appliance 10. The calculation unit 63 then sends the moisture content information to the display unit 90.

[0166] Display unit 90 is, for example, a monitor.

[0167] Additionally, the main unit 50 may also include an input section for receiving input information from the user. For example, the input section may have one or more buttons for accepting input from the user. These buttons may include, for example, a power button for switching the power on / off, a measurement start button for starting the measurement, etc.

[0168] [An example of an oral appliance installed in the disassembly / removal mechanism]

[0169] use Figure 10 An example of an oral appliance 10 installed in the disassembly and assembly unit 70 will be described. Figure 10 This is a schematic partial enlarged cross-sectional view showing an example of an oral appliance 10 installed in the disassembly and assembly unit 70.

[0170] like Figure 10 As shown, the oral appliance 10 is disposed on the mounting surface 72 of the disassembly and assembly operation section 70. Specifically, the connecting portion 40 of the oral appliance 10 is positioned on the mounting surface 72 by contacting the positioning member 72a. Furthermore, the connecting portion 40 of the oral appliance 10 is positioned by the positioning member 72a at a position where the electrode 41 is in physical contact with the connecting terminal 71. Thus, the electrode 41 of the oral appliance 10 is electrically connected to the connecting terminal 71 of the main body device 50. When the electrode 41 of the oral appliance 10 is electrically connected to the connecting terminal 71 of the main body device 50, the oral appliance 10 can be used through the main body device 50.

[0171] The pressing member 73 presses the connecting portion 40 of the oral appliance 10 toward the mounting surface 72 by the force of the elastic body. As a result, the connecting portion 40 of the oral appliance 10 is clamped between the mounting surface 72 and the pressing member 73 and thus fixed.

[0172] Furthermore, the protrusion 73a at one end E1 of the pressing member 73 is inserted into the mounting hole 42 of the connecting portion 40 of the oral appliance 10. This prevents the oral appliance 10 from falling off the disassembly / removal operation portion 70.

[0173] In this way, the oral appliance 10 is subjected to a pressing force formed by the pressing member 73, thereby fixing and installing the oral appliance 10 onto the main body device 50 while the electrode 41 is electrically connected to the connecting terminal 71. Moreover, the release of the pressing force formed by the pressing member 73 releases the fixation, allowing the oral appliance 10 to be easily removed from the main body device 50.

[0174] [Effect]

[0175] According to the oral appliance 10 of Embodiment 1, the following effects can be achieved.

[0176] The oral appliance 10 is a sheet-like oral appliance that is detachably mounted to the main oral appliance 50. The oral appliance 10 includes a functional section 20, a connecting section 40, and a wiring section 30. The functional section 20 has a sensor section 21 that acquires information within the oral cavity. The connecting section 40 has an electrical connection. The wiring section 30 has wiring 31 that connects the sensor section 21 to the electrical connection. The functional section 20, the connecting section 40, and the wiring section 30 are composed of a wiring layer 11 and multiple insulating layers 12 and 13. The wiring layer 11 has a first main surface PS1 and a second main surface PS2 opposite to the first main surface PS1. The multiple insulating layers 12 and 13 have a first insulating layer 12 disposed on the first main surface PS1 of the wiring layer 11 and a second insulating layer 13 disposed on the second main surface PS2 of the wiring layer 11. In the functional section 20, the thickness T1 of the first insulating layer 12 is less than the thickness T2 of the second insulating layer 13.

[0177] With this structure, the performance of the dental appliance 10, which is detachably mounted on the dental main body device 50, can be improved. Specifically, by making the thickness T1 of the first insulating layer 12 smaller than the thickness T2 of the second insulating layer 13, the influence of the first insulating layer 12 on the sensor unit 21 on the first main surface PS1 side of the wiring layer 11 can be reduced. As a result, the functional unit 20 can be protected, and the distance between the sensor unit 21 and the measuring area can be reduced, thereby improving the sensitivity of the sensor unit 21. Consequently, the detection accuracy of the sensor unit 21 can be improved.

[0178] The wiring layer 11 and multiple insulating layers 12 and 13 are stacked together. This structure allows for a reduction in the thickness of the oral appliance 10, making insertion into the oral cavity easier. Because the oral appliance 10 can be made thinner, it can also be used, for example, by people who cannot open their mouths wide, such as patients with temporomandibular joint disorders.

[0179] The wiring section 30 has a protective layer 32 disposed on the outer periphery of the wiring section 30. With this structure, when the oral appliance 10 is inserted into the oral cavity for use, the protective layer 32 is positioned at the location where the user's teeth will contact it. Thus, the wiring section 30 can be protected by the protective layer 32, and malfunctions such as wire breakage can be suppressed when the user's teeth contact the wiring section 30.

[0180] The sensor unit 21 has a sensor surface 21a for acquiring information about the measurement site within the oral cavity. The sensor surface 21a is disposed on the first main surface PS1 side of the wiring layer 11. With this structure, the detection accuracy of the sensor unit 21 can be further improved.

[0181] In the oral appliance 10, at least the functional part 20 is flexible. With this structure, the functional part 20 can be deformed and arranged to conform to the shape of the measurement site within the oral cavity. This increases the contact area between the functional part 20 and the measurement site. As a result, the sensor part 21 can cooperate with the measurement site to acquire information within the oral cavity, thus improving detection accuracy.

[0182] The electrical connection portion consists of one or more electrodes 41 exposed from at least one of the first insulating layer 12 and the second insulating layer 13. With this structure, an electrical connection between the oral appliance 10 and the main body device 50 can be easily established through physical contact.

[0183] Furthermore, in Embodiment 1, an example of an oral device 1A being an oral hygrometer for measuring the moisture content in the oral cavity was described, but it is not limited to this. The oral device 1A can be a device for acquiring information about the oral cavity and / or a device for irradiating energy into the oral cavity.

[0184] In Embodiment 1, an example of a flexible oral appliance 10 was described, but it is not limited to this. In the oral appliance 10, flexibility is not a necessary structure. The oral appliance 10 may also be non-flexible.

[0185] In Embodiment 1, an example of an oral appliance 10 having one sensor unit 21 was described, but it is not limited to this. The oral appliance 10 may have at least one of one or more sensor units 21 and one or more energy irradiation units.

[0186] In Embodiment 1, an example of an oral appliance 10 having a sensor unit 21 with an electrostatic capacitance sensor was described, but it is not limited to this. For example, the sensor unit 21 may have a sensor capable of acquiring information associated with biological information. For example, the sensor unit 21 may have at least one of the following: impedance measurement sensor, resistance sensor, load sensor, humidity sensor, pressure sensor, color sensor, temperature sensor, hardness sensor, vibration sensor, biosensor, etc.

[0187] In Embodiment 1, an example was described where the calculation unit 63 calculates the water content based on the change in frequency of electrostatic capacitance, but this is not a limitation. The calculation unit 63 can calculate information within the oral cavity based on information obtained from the oral appliance 10.

[0188] In Embodiment 1, an example of installing and removing the oral appliance 10 by applying and releasing pressure generated by the pressing member 73 was described, but this is not a limitation. For example, the oral appliance 10 can also be installed and removed by the pressing force of the pressing member 73 and / or electromagnetic force. For example, the electrode 41 of the oral appliance 10 can also be formed of a metal that reacts with a magnet. The metal that reacts with a magnet is, for example, iron, cobalt, nickel, etc. In addition, a magnet can be provided in the main body device 50. The electrode 41 of the oral appliance 10 can also be attracted to the placement surface 72 by the magnetic force of the magnet provided in the main body device 50.

[0189] In Embodiment 1, an example was described where the electrical connection part of the oral appliance 10 is an electrode 41 and the electrical connection conductor of the main body device 50 is a connection terminal 71, but this is not a limitation. Furthermore, the phrase "the state of electrically connecting the electrical connection part and the electrical connection conductor" is not limited to a state where the electrical connection part and the electrical connection conductor are in physical contact. "The state of electrically connecting the electrical connection part and the electrical connection conductor" may also include a state where the electrical connection part and the electrical connection conductor are electrically connected in a non-contact manner. For example, the electrical connection can also be achieved by wirelessly connecting the electrical connection part and the electrical connection conductor using a wireless communication device such as an RFID tag.

[0190] In Embodiment 1, an example of the functional unit 20 including the sensor unit 21 was described, but it is not limited to this. The functional unit 20 may include at least one of the sensor unit 21 for acquiring information in the oral cavity and the energy irradiation unit 22 for irradiating energy in the oral cavity.

[0191] In Embodiment 1, an example of the functional part 20 being flexible was described, but it is not a limitation. In the oral appliance 10, at least the functional part 20 needs to be flexible. For example, the entire oral appliance 10 may be flexible.

[0192] In Embodiment 1, an example of wiring section 30 having protective layer 32 was described, but it is not limited to this. For example, wiring section 30 may not have protective layer 32.

[0193] (Variation Example 1)

[0194] Figure 11A This is a schematic diagram showing the pressing member 73A of the modified example 1. Figure 11B This is a schematic diagram showing the oral appliance 10A of variant example 1. Figure 11A As shown, when viewed from the Z direction, the two protrusions 73a are arranged asymmetrically with respect to the center line extending in the X direction. Furthermore, as... Figure 11B As shown, when viewed from the Z direction, the two mounting holes 42 in the connecting part 40A are arranged asymmetrically with respect to the center line extending in the X direction. This structure allows for the determination of the mounting direction of the oral appliance 10A. Consequently, the oral appliance 10A can be mounted on the disassembly / removal operation part 70A without confusion between its front and back surfaces.

[0195] (Variation Example 2)

[0196] Figure 12 This is a simplified cross-sectional view of the dental appliance 10AA from variant example 2, shown under magnification. Figure 12 As shown, in the connection portion 40AA of the oral appliance 10AA, the electrode 41 is exposed from the second insulating layer 13. On the other hand, the electrode 41 is not exposed from the first insulating layer 12. In this case, a connection terminal 71 may also be provided on the pressing member 73 in the disassembly and assembly operation portion 70. With such a structure, the oral appliance 10AA can also be electrically connected to the main body device 50.

[0197] (Implementation Method 2)

[0198] The oral appliance according to Embodiment 2 of the present invention will be described. Furthermore, in Embodiment 2, the differences from Embodiment 1 will be mainly described. In Embodiment 2, the same or equivalent structural reference numerals as in Embodiment 1 will be used for description. In addition, descriptions that are repeated in Embodiment 1 will be omitted in Embodiment 2.

[0199] use Figure 13 An example of an oral appliance according to Embodiment 2 will be described. Figure 13 This is a schematic cross-sectional view showing an enlarged example of an oral appliance 10B according to Embodiment 2 of the present invention.

[0200] In Embodiment 2, the difference from Embodiment 1 lies in the fact that the thickness T4 of the wiring section 30B is greater than the thickness T3 of the functional section 20, and in the fact that it has multiple shielding layers 14 and 15.

[0201] like Figure 13 As shown, in the oral appliance 10B, the thickness T4 of the wiring portion 30B is greater than the thickness T3 of the functional portion 20. For example, the thickness T4 of the wiring portion 30B is more than twice and less than 1,000 times the thickness T3 of the functional portion 20.

[0202] By making the thickness T4 of the wiring section 30B greater than the thickness T3 of the functional section 20, the strength of the wiring section 30B can be improved.

[0203] The wiring section 30B has multiple shielding layers 14 and 15 disposed on multiple insulating layers 12, 13, 16, and 17. The wiring section 30B is constructed by stacking a wiring layer 11, multiple insulating layers 12, 13, 16, and 17 and multiple shielding layers 14 and 15.

[0204] In embodiment 2, the plurality of insulating layers 12, 13, 16, and 17 include, in addition to the first insulating layer 12 and the second insulating layer 13, a third insulating layer 16 and a fourth insulating layer 17. The first insulating layer 12 and the third insulating layer 16 are disposed on the first main surface PS1 side of the wiring layer 11. The second insulating layer 13 and the fourth insulating layer 17 are disposed on the second main surface PS2 side of the wiring layer 11.

[0205] In embodiment 2, the plurality of shielding layers 14 and 15 have two shielding layers. Specifically, the plurality of shielding layers 14 and 15 have a first shielding layer 14 and a second shielding layer 15.

[0206] The first shielding layer 14 is disposed on the first main surface PS1 side of the wiring layer 11 and is disposed between the first insulating layer 12 and the third insulating layer 16. Specifically, on the first main surface PS1 side of the wiring layer 11 of the wiring section 30B, the wiring layer 11, the first insulating layer 12, the first shielding layer 14 and the third insulating layer 16 are stacked in sequence.

[0207] The second shielding layer 15 is disposed on the second main surface PS2 side of the wiring layer 11, and is disposed between the second insulating layer 13 and the fourth insulating layer 17. Specifically, on the second main surface PS2 side of the wiring layer 11 of the wiring section 30B, the wiring layer 11, the second insulating layer 13, the second shielding layer 15 and the fourth insulating layer 17 are stacked in sequence.

[0208] Multiple shielding layers 14 and 15 form a GND. The multiple shielding layers 14 and 15 are formed, for example, from metals such as Cu, Ag, Au, Al, or carbon materials. The thicknesses of the first shielding layer 14 and the second shielding layer 15 are respectively more than 1 μm and less than 100 μm.

[0209] For example, wiring layer 11, multiple insulating layers 12, 13, 16, 17, and multiple shielding layers 14, 15 can also be formed from a multilayer flexible printed circuit board. Alternatively, the multiple shielding layers 14, 15 can also be formed by attaching conductive nonwoven fabric or metal foil to the multiple insulating layers 12, 13, 16, 17. Alternatively, multiple insulating layers 12, 13, 16, 17 and multiple shielding layers 14, 15 can be formed using a film with a metal film integrally formed of insulating and shielding layers, and then attached to wiring layer 11.

[0210] [Effect]

[0211] According to the oral appliance 10B of Embodiment 2, the following effects can be achieved.

[0212] In the oral appliance 10B, the thickness T4 of the wiring portion 30B is greater than the thickness T3 of the functional portion 20. This structure improves the mechanical strength of the wiring portion 30B. For example, in situations where the oral appliance 10B is inserted into the oral cavity, the wiring portion 30B may be bitten by the user's teeth. By increasing the thickness T4 of the wiring portion 30B to improve mechanical strength, deformation of the wiring portion 30B can be suppressed. Therefore, malfunctions such as wire breakage when external force is applied to the wiring portion 30B can be prevented.

[0213] The wiring section 30B has multiple shielding layers 14 and 15 disposed on multiple insulating layers 12 and 13. This structure can suppress noise generated from the wiring section 30B. Furthermore, by forming the multiple shielding layers 14 and 15 from materials with high rigidity such as metal or carbon, the mechanical strength of the wiring section 30B can be further improved.

[0214] Furthermore, in Embodiment 2, an example was described where the wiring section 30B has multiple shielding layers 14 and 15, but this is not a limitation. For example, the wiring section 30B may not have multiple shielding layers 14 and 15.

[0215] In Embodiment 2, an example of wiring section 30B having two shielding layers 14 and 15 was described, but it is not limited to this. Wiring section 30B may also have one or more shielding layers.

[0216] In Embodiment 2, an example was described where the first shielding layer 14 is disposed between the first insulating layer 12 and the third insulating layer 16, and the second shielding layer 15 is disposed between the second insulating layer 13 and the fourth insulating layer 17, but this is not a limitation. For example, the first shielding layer 14 may also be disposed between the wiring layer 11 and the first insulating layer 12. The second shielding layer 15 may also be disposed between the wiring layer 11 and the second insulating layer 13. The first shielding layer 14 and / or the second shielding layer 15 may also be formed as a GND pattern adjacent to the wiring 31 in the wiring layer 11.

[0217] (Implementation Method 3)

[0218] The oral device according to Embodiment 3 of the present invention will be described. Furthermore, in Embodiment 3, the differences from Embodiment 1 will be mainly described. In Embodiment 3, the same or equivalent structural reference numerals as in Embodiment 1 will be used for description. In addition, descriptions that are repeated in Embodiment 1 will be omitted in Embodiment 3.

[0219] use Figure 14A and Figure 14B An example of the oral device according to Embodiment 3 will be described. Figure 14A and Figure 14B This is a schematic perspective view of an example of the oral device 1C according to Embodiment 3 of the present invention. Additionally, Figure 14A and Figure 14B The display of display unit 90 is omitted in the text.

[0220] In Embodiment 3, the extension direction of the main body 60C of the oral cavity main body device 50C is the same as the disassembly and assembly direction of the oral cavity appliance 10C, and the oral cavity appliance 10C is installed on the disassembly and assembly operation part 70C in a deformed state, which is different from Embodiment 1.

[0221] like Figure 14A and Figure 14B As shown, the main body 60C of the oral cavity device 50C is formed by a rod-shaped member extending in the same direction as the assembly / disassembly direction of the oral cavity appliance 10C. Figure 14A and Figure 14B In the middle, the direction of disassembly and assembly of the oral appliance 10C is the X direction.

[0222] The protective part 80C is formed by a protrusion that extends in a direction intersecting the disassembly / assembly direction of the oral appliance 10C. The protective part 80C is located on the side of the main body 60C opposite to the side where the disassembly / assembly operation part 70C is located. The protective part 80C protrudes outward from the gripping part 61C. Furthermore, an inclined surface is formed on the protective part 80C to inhibit the flow of liquids such as saliva towards the gripping part 61C. This prevents saliva from flowing into the gripping part 61C.

[0223] The oral appliance 10C is formed as a sheet-like structure with a deformable length direction. In Embodiment 3, the oral appliance 10C as a whole is flexible. That is, the functional part 20, the wiring part 30, and the connecting part 40 in the oral appliance 10C are flexible. The oral appliance 10C is installed on the disassembly and assembly operation part 70C in a deformed state.

[0224] Figure 15A This is a schematic partial enlarged cross-sectional view showing an example of an oral appliance 10C installed in the disassembly and assembly unit 70C. Figure 15B yesFigure 15A A schematic disassembled view of the disassembly and assembly operation section 70C. Additionally, Figure 15A and Figure 15B This is a cross-sectional view showing the oral appliance 10C and the disassembly / assembly operation unit 70C cut off at the YZ plane.

[0225] like Figure 15A and Figure 15B As shown, the disassembly and assembly operation unit 70C has a mounting surface 72C that is curved in a concave or convex shape and a pressing member 73C that is curved in a concave or convex shape along the shape of the mounting surface 72C.

[0226] The mounting surface 72C is formed by a concave curvature. Specifically, the mounting surface 72C is formed by a trapezoidal concavity. The mounting surface 72C includes a flat bottom surface 72aa and a plurality of inclined surfaces 72ab, 72ac extending obliquely toward the bottom surface 72aa. A plurality of connection terminals 71 are disposed on the bottom surface 72aa of the mounting surface 72C.

[0227] The pressing member 73C is formed by convex bending along the shape of the configuration surface 72C. Specifically, the pressing member 73C is formed in a trapezoidal shape. The pressing member 73C includes a flat bottom surface 73ca and a plurality of inclined surfaces 72ab and 72ac extending obliquely toward the bottom surface 73ca.

[0228] like Figure 15A As shown, the oral appliance 10C is installed in the disassembly / removal operation section 70C by being pressed by the pressing member 73C. The oral appliance 10C is fixed by being clamped between the pressing member 73C and the mounting surface 72C, thereby deforming along the shape of the pressing member 73C and the mounting surface 72C. In embodiment 3, the oral appliance 10C is deformed into a trapezoidal shape protruding downward in the Z direction.

[0229] Specifically, the oral appliance 10C is clamped between the bottom surface 72aa of the configuration surface 72C and the bottom surface 73ca of the pressing member 73C, between the inclined surface 72ab of the configuration surface 72C and the inclined surface 73cb of the pressing member 73C, and between the inclined surface 72ac of the configuration surface 72C and the inclined surface 73cc of the pressing member 73C.

[0230] The multiple electrodes 41 of the oral appliance 10C are electrically connected to the multiple connection terminals 71 by physically contacting the multiple connection terminals 71 disposed on the bottom surface 72aa of the configuration surface 72C.

[0231] In this way, the oral appliance 10C is deformed into a trapezoidal shape and fixed to the disassembly and assembly operation unit 70C.

[0232] [Effect]

[0233] The oral appliance 10C according to Embodiment 3 can achieve the following effects.

[0234] In the oral appliance 10C, the functional part 20, the wiring part 30, and the connecting part 40 are flexible. Therefore, the oral appliance 10C is fixed in a state where it deforms along the shape of the disassembly / assembly operation part 70C. This prevents the oral appliance 10C from sagging. For example, if saliva or the like adheres to the oral appliance 10C, the weight of the saliva can cause it to sagging. By deforming the oral appliance 10C into a trapezoidal or similar shape for installation, the deformed shape of the oral appliance 10C can be maintained, thus preventing sagging. Furthermore, when using the oral appliance 10C in the oral cavity, it can deform along the shape of the contact area within the oral cavity. This improves measurement accuracy or irradiation accuracy.

[0235] Furthermore, in Embodiment 3, an example of the oral appliance 10C being flexible as a whole was described, but it is not limited to this. The oral appliance 10C can be stably fixed as long as it is deformed when installed on the disassembly and assembly operation part 70C, or parts of the oral appliance 10C can be formed of non-flexible components.

[0236] In Embodiment 3, an example of the oral appliance 10C being deformed into a trapezoidal shape protruding downwards was described, but it is not limited to this. For example, when viewed from the X direction, the oral appliance 10C can be deformed into a concave or convex shape.

[0237] Figures 16A-16C This is a schematic enlarged cross-sectional view showing an example of a variation of the oral appliance 10C. Additionally, Figures 16A-16C This shows a cross-sectional view with the connecting portion 40 of the oral appliance 10C cut off at the YZ plane. (See figure) Figure 16A As shown, it can also be that, when viewed from the X direction, the oral instrument 10C is deformed into a U-shape protruding downwards. For example... Figure 16B As shown, it can also be that, when viewed from the X direction, the oral instrument 10C is deformed into a V-shape protruding downwards. For example... Figure 16C As shown, when viewed from the X direction, the oral appliance 10C can also be deformed into an upward-protruding U-shape. In such a structure, sagging of the oral appliance 10C can also be prevented.

[0238] (Implementation Method 4)

[0239] The oral appliance according to Embodiment 4 of the present invention will be described. Furthermore, in Embodiment 4, the differences from Embodiment 1 will be mainly described. In Embodiment 4, the same or equivalent structural reference numerals as in Embodiment 1 will be used for description. In addition, in Embodiment 4, descriptions that are repeated in Embodiment 1 will be omitted.

[0240] use Figure 17An example of an oral appliance according to Embodiment 4 will be described. Figure 17 This is a schematic partial enlarged cross-sectional view showing an example of an oral appliance 10D according to Embodiment 4 of the present invention.

[0241] In Embodiment 4, the electrode 41 is exposed from both the first insulating layer 12 and the second insulating layer 13, which is different from Embodiment 1.

[0242] like Figure 17 As shown, in the connection portion 40D of the oral appliance 10D, the electrode 41 is exposed from both the first insulating layer 12 and the second insulating layer 13.

[0243] [Effect]

[0244] The oral appliance 10D according to embodiment 4 can achieve the following effects.

[0245] In the dental appliance 10C, the electrode 41 is exposed from both the first insulating layer 12 and the second insulating layer 13. This structure increases the flexibility of installation of the dental appliance 10C. For example, in the disassembly / removal operation section 70, when the connection terminal 71 is provided on the mounting surface 72, the electrode 41 of the dental appliance 10D can physically contact the connection terminal 71 on the first main surface PS1 side. In the disassembly / removal operation section 70, when the connection terminal 71 is provided on the pressing member 73, the electrode 41 of the dental appliance 10D can physically contact the connection terminal 71 on the second main surface PS2 side.

[0246] Alternatively, the upper and lower surfaces of the oral appliance 10D can be interchanged and installed on the disassembly and assembly operation unit 70. Thus, when the oral appliance 10D is installed on the disassembly and assembly operation unit 70, the sensor surface 21a of the sensor unit 21 can be fixed facing upwards, or the sensor surface 21a of the sensor unit 21 can be fixed facing downwards.

[0247] In this way, the electrode 41 is exposed from both the first insulating layer 12 and the second insulating layer 13, thereby increasing the degree of freedom in the installation method of the oral appliance 10D.

[0248] (Implementation Method 5)

[0249] The oral device according to Embodiment 5 of the present invention will be described. Furthermore, in Embodiment 5, the differences from Embodiment 1 will be mainly described. In Embodiment 5, the same or equivalent structural reference numerals as in Embodiment 1 will be used for description. In addition, descriptions that are repeated in Embodiment 1 will be omitted in Embodiment 5.

[0250] use Figure 18 An example of the oral device according to Embodiment 5 will be described. Figure 18This is a block diagram illustrating the main structure of an example of the oral device 1E according to Embodiment 5 of the present invention.

[0251] In Embodiment 5, the difference from Embodiment 1 lies in the fact that the functional part 20E of the oral appliance 10E has an energy irradiation part 22, and the main body device 50E of the oral appliance controls the energy irradiation part 22.

[0252] like Figure 18 As shown, in the oral appliance 10E, the functional part 20E has an energy irradiation part 22 that irradiates energy within the oral cavity. In Embodiment 5, an example of the oral appliance 10E being a laser therapy device will be described. The oral appliance 10E is detachably mounted to the main oral appliance 50E for use.

[0253] Figure 19A This is a schematic diagram representing an example of an oral appliance 10E. Figure 19B yes Figure 19A A schematic cross-sectional view of an example of an oral appliance 10E. (See attached image.) Figure 19A and Figure 19B As shown, the functional unit 20E has multiple energy irradiation units 22. In embodiment 5, the functional unit 20E has four energy irradiation units 22.

[0254] Multiple energy irradiation units 22 are, for example, vertical-cavity surface-emitting lasers (VCSELs). These multiple energy irradiation units 22 are mounted on the first main surface PS1 of the wiring layer 11 and covered from above by a first insulating layer 12A. The first insulating layer 12A has an insulator 12a disposed on the first main surface PS1 of the wiring layer 11 and a transparent resin film 12b adhered to the insulator 12a. Multiple holes 12c are provided in the insulator 12a to accommodate the multiple energy irradiation units 22. In the functional unit 20E, the resin film 12b is provided to close the multiple holes 12c of the insulator 12a. Laser light from the multiple energy irradiation units 22 passes through the resin film 12b of the first insulating layer 12A and irradiates the irradiation area inside the oral cavity.

[0255] The functional part 20E is flexible. Therefore, the functional part 20E can deform along the shape of the irradiation site inside the oral cavity.

[0256] In functional section 20E, the thickness T11 of the first insulating layer 12A is less than the thickness T12 of the second insulating layer 13. The thickness T11 of the first insulating layer 12A in functional section 20E is less than or equal to half the thickness T12 of the second insulating layer 13. Preferably, the thickness T11 of the first insulating layer 12A in functional section 20E is less than or equal to one-eighth the thickness T12 of the second insulating layer 13. This improves the irradiation efficiency of the laser in energy irradiation section 22.

[0257] return Figure 18 The main dental device 50E includes an input unit 91. The input unit 91 receives input information from the operating energy irradiation unit 22. The user inputs information into the input unit 91. For example, the input unit 91 can be one or more operation buttons, a touch panel, a microphone, etc. The input information input to the input unit 91 is sent to the control unit 62. Examples of input information include, for instance, laser irradiation, laser stop, timer, and output values.

[0258] The control unit 62 receives input information from the input unit 91 and controls the operation of the dental appliance 10E based on the input information. The control unit 62 controls multiple energy irradiation units 22 based on the input information. For example, if input information indicating laser irradiation is input to the input unit 91, the control unit 62 controls the multiple energy irradiation units 22 of the dental appliance 10E to irradiate laser light from the multiple energy irradiation units 22.

[0259] [Effect]

[0260] The oral appliance 10E according to embodiment 5 can achieve the following effects.

[0261] In the oral appliance 10E, the functional part 20E includes an energy irradiation part 22 that irradiates energy within the oral cavity. With this structure, energy can be irradiated at the irradiation site within the oral cavity.

[0262] The functional part 20E is flexible. As a result, the functional part 20E can deform along the shape of the irradiation site in the oral cavity and can make appropriate contact with the irradiation site.

[0263] The energy irradiation section 22 is disposed on the first main surface PS1 side of the wiring layer 11. In the functional section 20E, the thickness T11 of the first insulating layer 12A is smaller than the thickness T12 of the second insulating layer 13. This improves the laser irradiation efficiency of the energy irradiation section 22. By making the thickness T11 of the first insulating layer 12A smaller than the thickness T12 of the second insulating layer 13, the influence of the first insulating layer 12A on the laser irradiation from the energy irradiation section 22 can be reduced. Specifically, the distance between the energy irradiation section 22 and the irradiated area can be reduced, thus reducing the loss of the laser irradiated from the energy irradiation section 22.

[0264] Furthermore, in Embodiment 5, an example of a vertical-cavity surface-emitting laser (VCSEL) being used for the energy irradiation unit 22 was described, but the embodiment is not limited to this. The energy irradiation unit 22 simply needs to be capable of irradiating energy.

[0265] In embodiment 5, an example of functional unit 20E having four energy irradiation units 22 was described, but it is not limited to this. Functional unit 20E may have one or more energy irradiation units 22.

[0266] (Variation Example 3)

[0267] Figure 20A This is a schematic diagram of the oral appliance 10EA of variant example 3. Figure 20B yes Figure 20A A schematic sectional view of the oral appliance 10EA in variant example 3. Figure 20A and Figure 20B As shown, the oral appliance 10EA is used as a thermotherapy device. The energy irradiation section 22a of the functional section 20EA is a sheet heater. The sheet heater uses the heating of a resistive element for heating. Alternatively, the oral appliance 10EA may be such that, except for the portion heated by the energy irradiation section 22a, it is covered by a heat insulation member 18. In the oral appliance 10EA, the first main surface PS1 side of the wiring layer 11 is not covered by the heat insulation member 18.

[0268] (Implementation Method 6)

[0269] The oral device according to Embodiment 6 of the present invention will be described. Furthermore, in Embodiment 6, the differences from the main Embodiment 1 will be explained. In Embodiment 6, the same reference numerals as those used in Embodiment 1 will be used for structural reference numerals. In addition, in Embodiment 6, descriptions that are repeated in Embodiment 1 will be omitted.

[0270] use Figure 21 An example of the oral device according to Embodiment 6 will be described. Figure 21 This is a block diagram illustrating the main structure of an example of the oral device 1F according to Embodiment 6 of the present invention.

[0271] In Embodiment 6, the electrical connection part of the oral appliance 10F is an RFID (Radio Frequency Identification) tag 43, and the electrical connection conductor of the oral body device 50F is an antenna 78, which differs from Embodiment 1.

[0272] like Figure 21 As shown, in the dental appliance 10F, the connecting part 40E has an RFID tag 43 as an electrical connection part. The RFID tag 43 is electrically connected to the electrical connection conductor of the dental main body 50F via a wireless connection. That is, the RFID tag 43 is electrically connected to the antenna 78 of the dental main body 50F in a non-contact manner.

[0273] Figure 22 This is a schematic diagram representing an example of an oral appliance 10F. Figure 23 yes Figure 22 A schematic cross-sectional view of an example of an oral appliance 10F. (See attached image.) Figure 22 and Figure 23As shown, the RFID tag 43 is disposed in the connector 40F within the wiring layer 11. The RFID tag 43 is covered by multiple insulating layers 12 and 13. That is, the RFID tag 43 is not exposed from the multiple insulating layers 12 and 13.

[0274] Figure 24 This is a schematic diagram of an example of RFID tag 43. (As shown) Figure 24 As shown, the RFID tag 43 has an antenna 44 and an IC chip 45 connected to the antenna 44.

[0275] Antenna 44 is formed by spirally winding a conductive wire member. Antenna 44 is formed, for example, by a pattern of wiring conductors.

[0276] IC chip 45 is, for example, an RFIC chip (bare die) with input / output terminals. For example, IC chip 45 is an IC chip with RF circuitry for RFID tags, memory circuitry, control circuitry, etc. IC chip 45 is connected to sensor section 21 of functional section 20 via wiring 31.

[0277] Figure 25 This is a schematic circuit diagram of an example of RFID tag 43. (See diagram for example.) Figure 25 As shown, an antenna 44 is connected to the IC chip 45. A surface-mount capacitor C1 is connected in parallel to the antenna 44. The surface-mount capacitor C1 is, for example, a laminated ceramic surface-mount component. The antenna 44, the surface-mount capacitor C1, and the capacitance inherent in the IC chip 45 together form an antenna resonant circuit with a resonant frequency. However, this circuit is just one example, and the resonant circuit of the RFID tag 43 is not limited to this.

[0278] Figure 26 This is a schematic partial enlarged sectional view showing an example of an oral appliance 10F installed in the disassembly and assembly operation section 70F. Figure 26 This indicates that the oral appliance 10F is installed in the disassembly and assembly operation unit 70F, and the oral appliance 10F is electrically connected to the main unit 50F in a non-contact manner.

[0279] like Figure 26 As shown, the disassembly and assembly operation unit 70F has an antenna 78. In this specification, the antenna 78 is sometimes referred to as the main body side antenna 78. In addition, apart from the fact that the antenna 78 is provided in place of the connection terminal 71, the disassembly and assembly operation unit 70F has the same structure as the disassembly and assembly operation unit 70 of Embodiment 1.

[0280] The main-side antenna 78 is formed by spirally winding a conductive wire member. The main-side antenna 78 is formed, for example, by a wiring conductor pattern.

[0281] The main body antenna 78 is housed inside the main body device 50F. The main body antenna 78 is positioned below the mounting surface 72. Specifically, when the dental appliance 10F is mounted on the mounting surface 72 and installed in the disassembly / removal operation unit 70F, the main body antenna 78 is located below the antenna 44 of the RFID tag 43. That is, when the dental appliance 10F is mounted on the mounting surface 72 and installed in the disassembly / removal operation unit 70F, the main body antenna 78 faces the antenna 44 of the RFID tag 43.

[0282] When the antenna 44 of the oral appliance 10F faces the main body antenna 78 of the main body device 50, the RFID tag 43 is magnetically coupled to the main body antenna 78. As a result, an induced current flows in the antenna 44, and the IC chip 45 is activated. Thus, the oral appliance 10F can be used.

[0283] [Effect]

[0284] The oral appliance 10F according to embodiment 6 can achieve the following effects.

[0285] The electrical connection of the dental appliance 10F is an RFID tag 43. The electrical connection conductor of the dental main unit 50F is an antenna 78. The dental appliance 10F is electrically connected by wirelessly connecting the RFID tag 43 to the antenna 78 of the dental main unit 50F. With this structure, the electrical connection between the dental appliance 10F and the dental main unit 50F can be easily made.

[0286] (Implementation Method 7)

[0287] The oral appliance according to Embodiment 7 of the present invention will be described. Furthermore, in Embodiment 7, the differences from the main Embodiment 1 will be explained. In Embodiment 7, the same or equivalent structural reference numerals as in Embodiment 1 will be used. In addition, in Embodiment 7, descriptions that are repeated in Embodiment 1 will be omitted.

[0288] use Figure 27 An example of an oral appliance according to Embodiment 7 will be described. Figure 27 This is a schematic cross-sectional view showing an enlarged example of an oral appliance 10G according to Embodiment 7 of the present invention. Additionally, Figure 27 This is an example of a dental appliance 10G being installed in the disassembly / removal operation unit 70G.

[0289] In Embodiment 7, the oral appliance 10G differs from Embodiment 1 in that it is constructed in a bag-like shape.

[0290] like Figure 27As shown, the oral appliance 10G is configured as a bag-shaped structure with the first main surface PS1 of the wiring layer 11 facing outward and the second main surface PS2 of the wiring layer facing inward. Specifically, the oral appliance 10G is configured as a bag-shaped structure with an opening at one end.

[0291] The disassembly and assembly operation unit 70G has a cylindrical member 79 on which an oral instrument 10G is mounted. The cylindrical member 79 is formed in a cylindrical shape. In addition, the end of the cylindrical member 79 is formed in a hemispherical shape.

[0292] The oral appliance 10G is mounted on the disassembly / removal operation unit 70G by covering the columnar member 79. Furthermore, if the oral appliance 10G covers the columnar member 79, the electrode 41 of the oral appliance 10G is electrically connected to the connection terminal 71 of the disassembly / removal operation unit 70G.

[0293] [Effect]

[0294] The oral appliance 10G according to embodiment 7 can achieve the following effects.

[0295] The dental appliance 10G is configured as a bag-shaped structure with the first main surface PS1 of the wiring layer 11 facing outward and the second main surface PS2 of the wiring layer 11 facing inward. In this configuration, the dental appliance 10G can be installed in the disassembly / removal operation section 70G. Furthermore, the dental appliance 10G can be more securely fixed to the main dental device.

[0296] (Implementation Method 8)

[0297] The oral appliance according to Embodiment 8 of the present invention will be described. Furthermore, in Embodiment 8, the differences from Embodiment 1 will be mainly described. In Embodiment 8, the same or equivalent structural reference numerals as in Embodiment 1 will be used for description. In addition, descriptions that are repeated in Embodiment 1 will be omitted in Embodiment 8.

[0298] use Figure 28A and Figure 28B An example of an oral appliance according to Embodiment 8 will be described. Figure 28A This is a schematic cross-sectional view showing an enlarged example of an oral appliance 10H according to Embodiment 8 of the present invention. Figure 28B It was cut at line AA. Figure 28A A schematic cross-sectional view of the oral instrument 10H.

[0299] In embodiment 8, in the functional part 20H, a plurality of openings 12d are provided on the first insulating layer 12C, and a plurality of sensor parts 21b are exposed from the plurality of openings 12d, which is different from embodiment 1 in this respect.

[0300] like Figure 28A andFigure 28B As shown, in the functional part 20H of the oral appliance 10H, a plurality of openings 12d are provided on the first insulating layer 12C. A plurality of sensor parts 21b are disposed in the area exposed from the plurality of openings 12d. The area exposed from the plurality of openings 12d is the portion exposed from the plurality of openings 12d when the oral appliance 10H is viewed in the Z direction from the first main surface PS1 side of the wiring layer 11. In other words, the plurality of sensor parts 21b are disposed within the plurality of openings 12d. Within the plurality of openings 12d, two or more adjacent sensor parts 21b are spatially separated.

[0301] Multiple sensor units 21b are located inside the outer surface of the first insulating layer 12C. Furthermore, portions of the sensor surfaces of the multiple sensor units 21b are covered by the first insulating layer 12C. Therefore, a step 12da is formed in a portion of the first insulating layer 12C disposed on the sensor surfaces of the multiple sensor units 21b. Specifically, the step 12da is formed through a portion of the first insulating layer 12C that divides the opening 12d.

[0302] In embodiment 8, four openings 12d are provided on the first insulating layer 12C. Two sensor units 21b are disposed in the areas exposed from the four openings 12d respectively. Within each of the four openings 12d, two adjacent sensor units 21b are spatially separated by a distance S1. In other words, no insulating layer or wiring layer is disposed between two adjacent sensor units 21b.

[0303] In embodiment 8, the opening 12d is formed as a rectangle having a length direction in the Y direction. In other words, the opening 12d is formed as a slit extending in the Y direction. Furthermore, four openings 12d are arranged in the X direction. Within the opening 12d, two adjacent sensor units 21b are arranged in the Y direction.

[0304] In embodiment 8, the plurality of sensor units 21b are impedance measurement sensors or resistance sensors, and each has electrodes. The electrodes are formed of a plate-shaped conductive material. When viewed from the Z direction, the electrodes have, for example, a quadrilateral shape. The electrodes are formed of materials that are not easily corroded, such as Au, Ag, silver chloride, Ti, Pt, or carbon. Alternatively, the electrodes may also be formed of materials such as Cu, Al, or SUS. The electrodes may also be plated.

[0305] Figure 29 This is a schematic cross-sectional view showing an example of a state in which the oral appliance 10H of Embodiment 8 of the present invention is in contact with the measuring site 2. Figure 29 The measurement site 2 shown is the tongue. Therefore, a saliva layer 3 is formed on the surface of the measurement site 2. The saliva layer 3 is a layer containing saliva.

[0306] likeFigure 29 As shown, by making the thickness T1 of the first insulating layer 12C smaller than the thickness T2 of the second insulating layer 13, the height of the step 12da between the first insulating layer 12C and the sensor part 21b can be reduced. The height of the step 12da is the length in the Z direction. Therefore, when the functional part 20H of the oral appliance 10H contacts the measuring part 2, the contact state of the multiple sensor parts 21b relative to the measuring part 2 can be stabilized. Furthermore, the multiple sensor parts 21b can be arranged closer to the measuring part 2. As a result, the detection sensitivity of the multiple sensor parts 21b can be improved.

[0307] Furthermore, when a saliva layer 3 is present on the surface of the measurement site 2, the measurement values ​​acquired by the multiple sensor units 21b vary depending on the thickness of the saliva layer 3. For example, when the multiple sensor units 21b are resistance sensors, there is a tendency that the thinner the saliva layer 3, the greater the resistance value.

[0308] In the oral appliance 10H, the space S1 formed by the opening 12d is filled with a saliva layer 3, thereby ensuring that the thickness of the saliva layer 3 in contact with the multiple sensor units 21b remains constant. This allows for the stabilization of the measurement values ​​acquired by the multiple sensor units 21.

[0309] [Effect]

[0310] The oral appliance 10H according to embodiment 8 can achieve the following effects.

[0311] In the functional part 20H of the oral appliance 10H, a plurality of openings 12d are provided in the first insulating layer 12C. A plurality of sensor parts 21b are disposed in the areas exposed from the plurality of openings 12d. With this structure, the contact state of the plurality of sensor parts 21b relative to the measuring part 2 can be stabilized. Furthermore, the plurality of sensor parts 21b can be disposed closer to the measuring part 2. As a result, the detection sensitivity of the plurality of sensor parts 21b can be improved.

[0312] Within the plurality of openings 12d, two or more adjacent sensor units 21b are spatially separated by a distance S1. With this structure, for example, even when a saliva layer 3 is present on the surface of the measurement site 2, the measurement values ​​acquired by the plurality of sensor units 21b can be stabilized. That is, inconsistencies in the measurement values ​​acquired by the plurality of sensor units 21b can be suppressed.

[0313] Furthermore, since the functional part 20H is flexible, if the functional part 20H comes into contact with the measuring part 2, the functional part 20H will deform. In such a structure, the gap between the multiple sensor parts 21b and the measuring part 2 can also be reduced, thus enabling detection with higher accuracy.

[0314] Furthermore, by forming the opening 12d in a slit shape, it is possible to prevent the measuring part 2 from entering the opening 12d. This allows the space S1 formed by the opening 12d to be easily filled with the saliva layer 3. Consequently, inconsistencies in the measured values ​​of the multiple sensor parts 21b can be further suppressed.

[0315] Furthermore, in Embodiment 8, an example in which multiple openings 12d are provided in the first insulating layer 12C was described, but this is not a limitation. It is sufficient to provide one or more openings 12d in the first insulating layer 12C.

[0316] In embodiment 8, an example of opening 12d being formed in the shape of a slit was described, but it is not limited to this. For example, when viewed from the Z direction, opening 12d may also be formed in the shape of an ellipse, a triangle, a quadrilateral, a circle, etc.

[0317] In embodiment 8, an example in which two sensor units 21 are arranged in the area exposed from the opening 12d was described, but it is not limited to this. It is acceptable to arrange one or more sensor units 21 in the area exposed from the opening 12d.

[0318] In embodiment 8, an example was described in which two adjacent sensor units 21 are arranged separately with space S1 between them within the opening 12d, but this is not a limitation. For example, two or more sensor units 21b may also be arranged separately with an insulator between them within the opening 12d.

[0319] In Embodiment 8, an example was described in which a portion of the surface (sensor surface) of the plurality of sensor units 21b was covered by the first insulating layer 12C, but this is not a limitation. For example, the surface of the plurality of sensor units 21 may not be covered by the first insulating layer 12C.

[0320] In Embodiment 8, an example of multiple sensor units 21b being impedance measurement sensors or resistance sensors was described, but the embodiment is not limited to this. Furthermore, an example of multiple sensor units 21b being electrodes with a quadrilateral shape when viewed from the Z direction was described, but the embodiment is not limited to this.

[0321] In embodiment 8, an example of functional unit 20H having multiple sensor units 21b was described, but it is not limited to this. For example, functional unit 20H may also have one or more energy irradiation units.

[0322] In Embodiment 8, an example was described where the sensor unit 21b is an impedance measuring sensor or a resistance sensor and has electrodes, but it is not limited to this. For example, the sensor unit 21b may also be any other sensor with electrodes. Alternatively, the sensor unit 21b may also be a sensor without electrodes.

[0323] (Variation Example 4)

[0324] Figure 30A This is a schematic diagram of the oral appliance 10HA in variant example 4. Figure 30B yes Figure 30A A schematic cross-sectional view of the oral appliance 10HA in variant example 4. Figure 30A and Figure 30B The oral appliance 10HA shown is used as a high-frequency therapeutic device. The functional part 20HA has multiple energy irradiation parts 22b.

[0325] In the oral appliance 10HA, a plurality of openings 12e are provided in the first insulating layer 12D. A plurality of energy irradiation parts 22b of the functional part 20HA are exposed through the plurality of openings 12e.

[0326] In Modification 4, two openings 12e are provided on the first insulating layer 12D. An energy irradiation section 22b is provided in each area exposed from the two openings 12e.

[0327] In variation 4, the opening 12e is formed as a rectangle having a length direction in the X direction. In other words, the opening 12e is formed as a slit extending in the X direction. Furthermore, the two openings 12e are arranged in the Y direction.

[0328] In Modification 4, multiple energy irradiation sections 22b have electrodes. The electrodes are formed of a plate-shaped conductive material. When viewed from the Z direction, the electrodes, for example, have a rectangular shape extending in the X direction. The material forming the electrodes is the same as that of the electrodes in the sensor section 21 of Embodiment 8. A high-frequency current is supplied to the multiple electrodes. The supply of the high-frequency current is controlled by the main body device 50.

[0329] In the oral appliance 10HA, by making the thickness T11 of the first insulating layer 12D smaller than the thickness T12 of the second insulating layer 13, the step 12ea between the electrode surfaces of the plurality of energy irradiation sections 22b and the surface of the first insulating layer 12B can be reduced. With this structure, the contact state of the plurality of energy irradiation sections 22b relative to the measurement site 2 can be stabilized. Furthermore, the plurality of energy irradiation sections 22b can be arranged closer to the measurement site 2. Therefore, the irradiation efficiency of the plurality of energy irradiation sections 22b can be improved.

[0330] Furthermore, in Variation 4, an example of a high-frequency therapeutic device for the oral appliance 10HA was described, but it is not limited to this. The oral appliance 10HA can also be a low-frequency therapeutic device. In this case, a low-frequency current is supplied between multiple electrodes.

[0331] (Implementation Method 9)

[0332] The oral appliance according to Embodiment 9 of the present invention will be described. Furthermore, in Embodiment 9, the differences from Embodiment 1 will be mainly described. In Embodiment 9, the same or equivalent structural reference numerals as in Embodiment 1 will be used for description. In addition, in Embodiment 9, descriptions that are repeated in Embodiment 1 will be omitted.

[0333] use Figures 31-33 An example of an oral appliance according to Embodiment 9 will be described. Figure 31 This is a schematic cross-sectional view showing an enlarged example of an oral appliance 10I according to Embodiment 9 of the present invention. Figure 32 This is a schematic diagram illustrating an example of an oral appliance 10I according to Embodiment 9 of the present invention. Figure 33 This is a schematic cross-sectional view showing an enlarged example of an oral appliance 10I according to Embodiment 9 of the present invention.

[0334] In Embodiment 9, the correction sensor unit 21B is provided in the connection part 40I, which is different from Embodiment 1.

[0335] like Figures 31-33 As shown, the oral appliance 10I has a measuring sensor unit 21A and a correction sensor unit 21B. In Embodiment 9, the measuring sensor unit 21A is the same as the sensor unit 21 in Embodiment 1.

[0336] <Modified Sensor Section>

[0337] The correction sensor unit 21B is positioned differently from the measurement sensor unit 21A to acquire correction information for correcting the information acquired by the measurement sensor unit 21A. The correction information is extraoral information.

[0338] The correction sensor unit 21B has the same structure as the measurement sensor unit 21A. In Embodiment 9, the measurement sensor unit 21A is an electrostatic capacitance sensor, and the correction sensor unit 21B is an electrostatic capacitance sensor identical to the measurement sensor unit 21A. The measurement sensor unit 21A measures the electrostatic capacitance of the measurement site 2A inside the oral cavity, while the correction sensor unit 21B measures the electrostatic capacitance of the environment outside the oral cavity.

[0339] The measuring sensor unit 21A is disposed in the functional unit 20I within the wiring layer 11, while the correction sensor unit 21B is disposed in at least one of the wiring portion 30 and the connecting portion 40I within the wiring layer 11. For example, the correction sensor unit 21B may also be disposed in the wiring portion 30, the connecting portion 40I, or a portion spanning the wiring portion 30 and the connecting portion 40I within the wiring layer 11. In embodiment 9, the correction sensor unit 21B is disposed in the connecting portion 40I within the wiring layer 11. Therefore, when using the oral appliance 10I, the measuring sensor unit 21A is disposed inside the oral cavity, while the correction sensor unit 21B is disposed outside the oral cavity.

[0340] The dental appliance 10I has two electrodes 41a connected to the measuring sensor unit 21A and two electrodes 41b connected to the correction sensor unit 21B. When the dental appliance 10I is installed on the main body device 50, the multiple electrodes 41a and 41b are electrically connected to the multiple connection terminals 71 of the main body device 50.

[0341] When the main body device 50 is electrically connected to the oral appliance 10I, it acquires measurement information obtained by the measurement sensor unit 21A and correction information obtained by the correction sensor unit 21B. The main body device 50 corrects the measurement information obtained by the measurement sensor unit 21A based on the correction information obtained by the correction sensor unit 21B. In embodiment 9, the main body device 50 corrects the electrostatic capacitance obtained by the measurement sensor unit 21A based on the electrostatic capacitance obtained by the correction sensor unit 21B. The correction processing may also be performed by the calculation unit 63, for example. Alternatively, the main body device 50 may also include a correction processing unit that performs this correction processing.

[0342] [Effect]

[0343] According to the oral appliance 10I of embodiment 9, the following effects can be achieved.

[0344] The dental appliance 10I includes a correction sensor unit 21B, which is positioned differently from the measurement sensor unit 21A. This correction sensor unit 21B acquires correction information for correcting information acquired by the measurement sensor unit 21A. With this structure, correction information for correcting information acquired by the measurement sensor unit 21A can be acquired. Since individual performance inconsistencies exist in the dental appliance 10I, correction is more effective in suppressing these inconsistencies. Because the dental appliance 10I can acquire correction information at a position different from the measurement sensor unit 21A, it is more useful for correcting information acquired by the measurement sensor unit 21A.

[0345] The correction sensor unit 21B is disposed in at least one of the wiring portion 30 and the connection portion 40I in the wiring layer 11. With this structure, when using the oral appliance 10I, the correction sensor unit 21B can be disposed outside the oral cavity. Therefore, information from outside the oral cavity can be acquired as correction information.

[0346] Furthermore, in Embodiment 9, an example of an oral appliance 10I having one measuring sensor unit 21A was described, but it is not limited to this. The oral appliance 10I may have one or more measuring sensor units 21A.

[0347] In embodiment 9, an example of an oral appliance 10I having one correction sensor unit 21B was described, but it is not limited to this. The oral appliance 10I may have one or more correction sensor units 21B.

[0348] In Embodiment 9, an example was described where the measuring sensor unit 21A and the correction sensor unit 21B are electrostatic capacitance sensors, but this is not a limitation. Similar to Embodiment 1, various sensors can be used as the measuring sensor unit 21A and the correction sensor unit 21B.

[0349] In Embodiment 9, an example of modifying the main device 50 was described, but it is not limited to this. For example, the oral appliance 10I may also be modified. For example, the oral appliance 10I may also have a modification processing circuit for modifying the device.

[0350] In Embodiment 9, an example with four electrodes 41a and 41b for the connection portion 40I was described, but it is not limited to this. For example, if the measuring sensor portion 21A and the correction sensor portion 21B are potential sensors, either the positive electrode or the negative electrode may be shared in the measuring sensor portion 21A and the correction sensor portion 21B.

[0351] (Variation Example 5)

[0352] Figure 34 This is a schematic diagram of the oral appliance 10IA of variant 5. Figure 35 yes Figure 34 A schematic cross-sectional view of the oral appliance 10IA, a variation of Example 5. (See attached image.) Figure 34 and Figure 35 As shown, in the oral appliance 10IA, the correction sensor unit 21C is arranged side by side with the functional unit 20IA in the wiring layer 11. Furthermore, the correction sensor unit 21C is configured to acquire information within the oral cavity with a different detection sensitivity than the measurement sensor unit 21A. This suppresses inconsistencies in measurement values ​​caused by inconsistencies in the thickness T1 of the first insulating layer 12.

[0353] The correction sensor unit 21C is positioned so as not to overlap with the measurement sensor unit 21A in the Z direction. Specifically, the correction sensor unit 21C is arranged side-by-side with the measurement sensor unit 21A along the first insulating layer 12 in the wiring layer 11 of the functional unit 20IA. In Modification 5, the measurement sensor unit 21A and the correction sensor unit 21C are arranged adjacent to each other in the X direction. Alternatively, the correction sensor unit 21C and the measurement sensor unit 21A may be separated and not adjacent to each other.

[0354] like Figure 35 As shown, in the oral appliance 10IA, the functional part 20IA is brought into contact with the measurement site 2B inside the oral cavity. The measurement site 2B is, for example, the tongue. The measurement sensor part 21A and the correction sensor part 21C acquire information from the measurement site 2B inside the oral cavity. The correction sensor part 21C is configured to acquire information from inside the oral cavity with a different detection sensitivity than the measurement sensor part 21A. Therefore, the information (measured values) acquired by the measurement sensor part 21A and the correction sensor part 21C are different.

[0355] Figure 36 This is a coordinate graph illustrating an example of the relationship between the measured values ​​of the measuring sensor unit 21A and the correction sensor unit 21C. For example... Figure 36 As shown, when the thickness of the first insulating layer 12 is t1, the measured value of the measuring sensor unit 21A is Xm1, and the measured value of the correction sensor unit 21C is Xc1. When the thickness of the first insulating layer 12 is t2, the measured value of the measuring sensor unit 21A is Xm2, and the measured value of the correction sensor unit 21C is Xc2. Furthermore, t1 < t2. In this case, the correction sensor unit 21C is configured to satisfy (Xm2 / Xc2) ≠ (Xm1 / Xc1). Therefore, by calculating the ratio (Xm / Xc) of the measured value Xm of the measuring sensor unit 21A to the measured value Xc of the correction sensor unit 21C, the thickness T1 of the first insulating layer 12 can be estimated and corrected.

[0356] For example, when the correction sensor unit 21C is an electrostatic capacitive sensor with comb-tooth electrodes, the detection sensitivity of the correction sensor unit 21C can be changed by altering the line spacing and / or line width of the comb teeth.

[0357] In this way, by using a correction sensor unit 21C with a different detection sensitivity than the measuring sensor unit 21A in the oral appliance 10IA, the thickness T1 of the first insulating layer 12 can be estimated and corrected. As a result, inconsistencies in the measured values ​​caused by inconsistencies in the thickness T1 of the first insulating layer 12 can be suppressed.

[0358] Although the invention has been fully described with reference to the accompanying drawings and in connection with preferred embodiments, various modifications and alterations will be apparent to those skilled in the art. It should be understood that such modifications and alterations are included therein as long as they do not depart from the scope of the invention based on the appended claims.
