Description

  The present invention relates to an intraoral pressure measuring device.

With the progress of an aging society, the number of people with eating and swallowing disorders is expected to increase. Eating and swallowing disorders occur due to aging-related diseases (such as stroke and cancer) and muscle weakness.
In particular, elderly people may have infections due to malnutrition, poor physical strength, and poor immunity if they cannot eat enough, but if they are eaten forcibly, they may fall into life-threatening conditions such as aspiration pneumonia due to dysphagia .

  Eating / dysphagia is associated with tongue pressure, lip pressure, and cheek pressure. That is, when chewing, food is collected into a bolus by tongue pressure, and when swallowed, the bolus is transferred from the oral cavity to the pharyngeal esophagus through coordinated movement of tongue pressure, cheek pressure, and lip pressure. Therefore, tongue pressure, lip pressure, and cheek pressure play important roles in eating and swallowing exercises.

  In general, video x-ray fluoroscopy (VF) examination of swallowing, palpation of pharyngeal movement, water drinking test, and the like are used for diagnosis of eating / swallowing disorders (for example, paragraph [0002] of Patent Document 1). reference). The drinking test performed as a screening test is to pour 3 ml of cold water into the subject's oral floor, order swallowing, and cause swallowing to be repeated twice after swallowing. Then, the eating / swallowing function is evaluated based on a predetermined evaluation criterion.

  However, the video fluoroscopy (VF) examination is complicated and expensive, and the burden on the subject is large. Also, in the palpation and drinking test, the evaluator's subjectivity may be included in the evaluation.

On the other hand, an intraoral pressure measuring device that measures intraoral pressures such as tongue pressure, lip pressure, and cheek pressure has been developed (see, for example, Patent Document 2).
One of the screening tests for diagnosis of eating and swallowing functions is to measure the maximum strength of tongue muscle strength generated by the action of the tongue, especially when chewing or swallowing food.

  The intraoral pressure measuring device described in Patent Document 2 detects the air pressure when a balloon (oral pressure measuring pad) inflated by applying a predetermined pressure in advance is inserted into the oral cavity and pressed with the tongue to detect the tongue pressure. Is to measure. Patent Document 2 describes the measurement of swallowing tongue pressure by continuously monitoring a change in pressure when a swallowing operation is performed with a balloon in a state where liquid is contained in the mouth (paragraph). [0025]).

  However, in the conventional intraoral pressure measuring device, when measuring intraoral pressure such as tongue pressure during swallowing, the oral cavity is used from the outside of the oral cavity using, for example, a syringe before and after positioning the balloon (oral pressure measuring pad) in the oral cavity. It is necessary to pour water inside. For this reason, there exists a possibility that the position of the pad for oral cavity pressure measurement may shift | deviate during water injection, and there existed a problem that the stable measurement became difficult.

  This invention is made | formed in view of an above described situation, and makes it a subject to provide the intraoral pressure measuring apparatus which can measure the intraoral pressure at the time of swallowing simply and stably.

  In order to solve the above-mentioned problems, an intraoral pressure measuring device according to the present invention includes a hollow part having a space inside, and a tubular connecting part that is connected to the hollow part and communicates with the inside of the hollow part. And a water injection means for injecting water into the oral cavity from the water injection outlet during measurement of the oral pressure. .

In such a configuration, when measuring the intraoral pressure during swallowing, first, an intraoral pressure measuring pad is inserted into the oral cavity and positioned. Then, by operating the water injection means, water is injected into the oral cavity from the water injection outlet portion attached to the pad for measuring the intraoral pressure. For this reason, before and after positioning the intraoral pressure measurement pad in the oral cavity, there is no need to inject water into the oral cavity from outside the oral cavity using, for example, a syringe, etc., and the position of the intraoral pressure measurement pad is shifted during the injection. Can be suppressed. Subsequently, during swallowing to swallow water injected into the oral cavity, the intraoral pressure is measured by pressing the intraoral pressure measurement pad with the intraoral pressure.
Therefore, according to the present invention, it is possible to provide an intraoral pressure measuring device capable of easily and stably measuring the intraoral pressure during swallowing.

  In the intraoral pressure measuring device, the water injection means includes a water injection bag having a space in which water can be filled, and the water injection outlet provided in the water injection bag, and is connected to the oral pressure measuring pad. It is preferable that the water previously filled in the water injection bag is injected into the oral cavity from the water injection outlet portion by the engagement pressure or the oral pressure by the subject at the time of measurement.

  In such a configuration, with the intraoral pressure measurement pad positioned in the oral cavity, the subject can apply an external force by biting the water injection bag or pressing it with the oral pressure, so that the oral cavity can enter the oral cavity from the water injection outlet portion of the water injection bag. Can be easily watered.

  In the intraoral pressure measuring device, it is preferable that a valve that is opened by a subject's meshing pressure or intraoral pressure is provided at the water injection outlet.

  In such a configuration, when an external force is applied to the water injection bag, the valve provided at the water injection outlet is opened, and when the external force is not applied to the water injection bag, the valve provided at the water injection outlet is not opened. Therefore, since leakage of water from the water injection bag can be suppressed, a certain amount of water can be injected into the oral cavity more reliably.

  In the intraoral pressure measuring device, the water injection means includes a water supply means for supplying a certain amount of water from the outside of the oral cavity toward the water injection outlet, and water supplied from the water supply means for the intraoral pressure measurement pad. It is preferable to have a water injection tube that is sent to the water injection outlet portion that is continuously provided.

  In such a configuration, when the water supply means is operated in a state where the intraoral pressure measurement pad is positioned in the oral cavity, water can be easily injected into the oral cavity from the water injection outlet through the water injection tube. .

  In the intraoral pressure measuring device, it is preferable that the water supply means supplies water by a manual operation by an operator.

  In such a configuration, the water supply means can be easily operated with a simple configuration.

  In the intraoral pressure measuring device, it is preferable that the water supply means supplies water by operation of an electric actuator.

  In such a configuration, the water supply means can be easily operated, and a certain amount of water can be more reliably injected into the oral cavity.

  In the intraoral pressure measuring device, the intraoral pressure measuring pad is preferably one selected from a cheek pressure measuring pad, a tongue pressure measuring pad, and a lip pressure measuring pad.

  In such a configuration, one of the cheek pressure measuring pad, the tongue pressure measuring pad, and the lip pressure measuring pad is selected and used. This makes it possible to easily and stably measure the cheek pressure, tongue pressure, and lip pressure during swallowing.

(First embodiment)
FIG. 1 is a configuration diagram schematically showing an intraoral pressure measuring device 100 according to the first embodiment of the present invention. As shown in FIG. 1, the intraoral pressure measuring device 100 includes a cheek pressure measuring pad 2, a tube 4, a main body 5, and a communication terminal 6.
In this embodiment, the intraoral pressure measuring device 100 includes a tongue pressure measuring pad 1 (see FIG. 3) and a lip pressure measuring pad 3 (see FIG. 4) that can be used in place of the cheek pressure measuring pad 2. It has more.

  2A is a side view of the buccal pressure measurement pad 2, FIG. 2B is a cross-sectional view taken along line IIb-IIb in FIG. 2A, and FIG. 2C is for buccal pressure measurement. 3 is a perspective view of a pad 2. FIG.

The cheek pressure measuring pad 2 is used for measuring the pressing force (cheek pressure) of the cheek to the molar tooth.
As shown in FIG. 2, the buccal pressure measurement pad 2 includes a buccal pressure measurement hollow portion 21, a buccal pressure measurement connection portion 22, and a wing portion 23.

  The cheek pressure measuring hollow portion 21 has a space 211 (see FIG. 2B) inside. The cheek pressure measuring hollow portion 21 has a substantially oval shape (track shape) when viewed from above or below (see FIG. 2B), and has a substantially oval shape (track shape) when viewed from the side. (See Fig. 2 (a)). The cheek pressure measuring hollow portion 21 is configured such that the lateral width dimension B2 is smaller than the vertical height dimension H2. The buccal pressure measurement connection portion 22 is connected to the buccal pressure measurement hollow portion 21. The cheek pressure measurement connection portion 22 communicates with the inside of the cheek pressure measurement hollow portion 21 and has a tubular shape.

  The wing portion 23 is connected to the side surface 212 of the cheek pressure measuring hollow portion 21. The wing portion 23 has a water injection bag 231 (see FIG. 2B) that has a substantially rectangular flat bag shape in plan view, and a water injection outlet portion 232 (FIG. 2B) provided on the side surface of the water injection bag 231. Reference). Thus, the water injection outlet part 232 is fixed to the cheek pressure measurement hollow part 21 via the water injection bag 231. That is, the water injection outlet 232 is attached to the cheek pressure measuring pad 2. Here, the wing part 23 functions as a water injection means for injecting water into the oral cavity from the water injection outlet part 232 at the time of measuring the cheek pressure during swallowing, and may be hereinafter referred to as the water injection means 23.

  The water injection bag 231 is connected to the buccal pressure measurement hollow portion 21 of the buccal pressure measurement pad 2 and has a space 233 (see FIG. 2B) that can be prefilled with water and stored therein. ing. The water injection outlet 232 has a water injection port 234 (see FIG. 2B) through which water in the water injection bag 231 is injected.

  The wing part 23 is provided in parallel to the central axis L2 (see FIG. 2B) of the cheek pressure measuring hollow part 21 and the cheek pressure measuring connecting part 22. The wing part 23 is positioned between the upper molar and the lower molar in a state where the cheek pressure measuring hollow part 21 is disposed between the cheek and the molar part dentition.

  The water injection outlet 232 is provided with a valve 235 that is opened by the subject's meshing pressure. The valve 235 has a substantially disk shape, and a part of the outer peripheral edge of the valve 235 is joined to the peripheral part of the water injection port 234 in the water injection outlet part 232. This joining may be performed by integral molding, or by fusion or adhesion. The valve 235 is opened by deformation and water pressure of the water injection bag 231 when the subject bites the water injection bag 231 of the wing part 23 between the upper molar and the lower molar. However, the valve 235 is omitted when leakage of water from the water injection outlet 232 before measurement can be almost ignored, for example, when the water injection outlet 234 of the water injection outlet 232 is formed by a cross-shaped cut. (The same applies to valves 135 and 345 described later).

  The cheek pressure measuring pad 2 is integrally formed of an elastic material. As the elastic material, silicone rubber is used here, but is not limited thereto, and various natural rubbers, synthetic rubbers, and the like can be used. Here, the cheek pressure measuring pad 2 is formed by injection molding or compression molding. However, the wing portion 23 may be formed as a separate body and joined to the cheek pressure measuring hollow portion 21 by fusion, adhesion, or the like.

  The cheek pressure measuring pad 2 is airtight between the inside and outside. Further, the cheek pressure measuring pad 2 holds the internal space 211 by its own elastic force. That is, even when the external pressure is applied and deformed, when the external pressure is removed, the natural shape is quickly restored to its original shape. Therefore, it is not necessary to apply a predetermined pressure in advance in the cheek pressure measuring pad 2 to inflate, and a special pressurizing device is also unnecessary.

  3 (a) is a plan view of the tongue pressure measuring pad 1, FIG. 3 (b) is a sectional view taken along line IIIb-IIIb of FIG. 3 (a), and FIG. 3 (c) is for measuring tongue pressure. 2 is a perspective view of a pad 1.

The valve 135 has a substantially disk shape, and a part of the outer peripheral edge of the valve 135 is joined to the peripheral part of the water injection port 134 in the water injection outlet part 132. Then, the valve 135 is opened by the deformation and water pressure of the water injection bag 131 when the subject presses the water injection bag 131 with the engagement pressure or the lip pressure.

  Here, the tongue pressure measuring pad 1 is formed of the same material and molding method as the cheek pressure measuring pad 2, and has the airtightness and the shape-returning property similar to the tongue pressure measuring pad 1. doing.

  4A is a plan view of the lip pressure measuring pad 3, FIG. 4B is a cross-sectional view taken along line IVb-IVb in FIG. 4A, and FIG. 4C is a lip pressure measuring pad. 3 is a perspective view of a pad 3. FIG.

The lip pressure measuring pad 3 is used for measuring the pressing force (lip pressure) between the upper lip and the lower lip.
As shown in FIG. 4, the lip pressure measuring pad 3 includes a lip pressure measuring hollow portion 31, a lip pressure measuring connecting portion 32, and a collar portion 33.

  The lip pressure measuring hollow portion 31 has a space 311 (see FIG. 4B) inside. The lip pressure measuring hollow portion 31 has a substantially rectangular or substantially pentagonal shape when viewed from above or below (see FIG. 4A), and has a substantially rectangular or substantially oval shape (track shape) when viewed from the side. (See FIG. 4 (b)). The lip pressure measuring hollow portion 31 is configured such that the lateral width dimension B3 is larger than the vertical height dimension H3. The lip pressure measuring connection portion 32 is connected to the lip pressure measuring hollow portion 31. The lip pressure measuring connection portion 32 communicates with the inside of the lip pressure measuring hollow portion 31 and has a tubular shape.

  The collar portion 33 is provided on the opposite side of the lip pressure measurement connecting portion 32 in the lip pressure measurement hollow portion 31 and has a substantially square plate shape. The flange 33 is provided perpendicular to the central axis L3 (see FIG. 4C) of the lip pressure measuring hollow portion 31 and the lip pressure measuring connecting portion 32. The heel part 33 is positioned between the front teeth and the lips in a state where the lip pressure measuring hollow part 31 is disposed between the upper lip and the lower lip.

  On the opposite side of the lip 33 from the lip pressure measuring pad 3 on the lip pressure measuring pad 3, a water injection bag 341 of the water injection means 34 is connected. The water injection means 34 may be integrally formed with the lip pressure measuring pad 3, or may be joined by fusion, adhesion or the like. The water injection means 34 includes a water injection bag 341 having an outer shape of a bag shape having a substantially elliptical shape, and a water injection outlet 342 provided on the opposite side of the water injection bag 341 from the flange 33. The water injection means 34 has a function of injecting water into the oral cavity from the water injection outlet 342 when measuring the lip pressure during swallowing.

  The water injection bag 341 has a space 343 (see FIG. 4B) that can be filled with water in advance and stored. The water injection outlet 342 has a water injection port 344 (see FIG. 4B) through which water in the water injection bag 341 is injected.

  The water injection outlet 342 is provided with a valve 345 that is opened by tongue pressure by the subject. The valve 345 has a substantially disk shape, and a part of the outer peripheral edge of the valve 345 is joined to the peripheral part of the water injection port 344 in the water injection outlet part 342. The valve 345 is opened by deformation and water pressure of the water injection bag 341 when the subject presses the water injection bag 341 with tongue pressure.

  Here, the lip pressure measuring pad 3 is formed of the same material and molding method as the tongue pressure measuring pad 1 and has the airtightness and the shape's natural returnability like the tongue pressure measuring pad 1. doing. However, the collar portion 33 may be formed as a separate body and joined to the lip pressure measurement hollow portion 31 by fusion, adhesion, or the like.

  As shown in FIG. 1, the tube 4 includes a buccal pressure measurement connection portion 22 (see FIG. 2) of the buccal pressure measurement pad 2 and a tongue pressure measurement connection portion 12 (see FIG. 3) of the tongue pressure measurement pad 1. Alternatively, it is detachably connected to the lip pressure measuring connecting portion 32 (see FIG. 4) of the lip pressure measuring pad 3. Here, the end portion on the distal end side of the tube 4 is inserted into and fitted into the opening of the cheek pressure measurement connection portion 22, the tongue pressure measurement connection portion 12, or the lip pressure measurement connection portion 32.

  Since the lip pressure measuring connection portion 32 (see FIG. 4) needs to smoothly pull out the inner mold when the lip pressure measuring pad 3 is molded, the tongue pressure measuring connection portion 12 and the cheek pressure measuring portion are used. The inner diameter is larger than that of the connecting portion 22. For this reason, the tube 4 has a lip pressure of the lip pressure measuring pad 3 (see FIG. 4) through a relatively small cylindrical adapter (not shown) whose inner diameter is the same as that of the tongue pressure measuring connecting portion 12. It is configured to be connected to the measurement connection portion 32.

  The main body portion 5 is provided with a main body side connection portion 51 that is detachably connected to an end portion of the tube 4 on the proximal end side (the side opposite to the cheek pressure measurement pad 2). Here, the end portion on the distal end side of the main body side connection portion 51 is inserted into and fitted into the opening at the end portion on the proximal end side of the tube 4. The main body 5 measures intraoral pressures such as cheek pressure, tongue pressure, and lip pressure from the air pressure transmitted to the main body side connection portion 51.

FIG. 5 is a block diagram showing the configuration of the main body 5. FIG. 6 is a block diagram showing the configuration of the control means 53 shown in FIG.
As shown in FIG. 5, the main body 5 includes a piezoelectric electricity conversion unit 52, a control unit 53, an operation unit 54, a display unit 55, a storage unit 56, and a communication unit 57.

  The electrical pressure converting means 52 detects the air pressure transmitted from the cheek pressure measuring pad 2 or the like via the tube 4 to the main body side connecting portion, and converts the air pressure into an electrical signal. The electrical pressure conversion means 52 uses, for example, a strain gauge pressure transducer provided in the main body side connection portion 51 or a condenser microphone that converts a change in capacitance between electrodes that changes due to air vibration into an electrical signal. It may be a thing. Alternatively, an omnidirectional microphone or the like that detects a change in the outflow sound of air from the pinhole may be used in a sealed space provided in the main body side connection unit 51.

  The control means 53 includes a CPU (Central Processing Unit) and a memory, and controls the entire main body 5. Further, the control means 53 processes the electrical signal obtained from the piezoelectric electricity conversion means 52 as measurement information, and transmits the measurement result to the display means 55. In addition, the control unit 53 transmits the operation information from the operation unit 54 and the storage information from the storage unit 56 to the communication unit 57, and communicates with the communication terminal 6 using radio waves such as Bluetooth (registered trademark). be able to.

  As shown in FIG. 6, the control unit 53 includes an amplifier 531, a frequency filter 532, an A / D converter 533, and a conversion unit 534. The amplifier 531 amplifies the electrical signal obtained from the pressure electrical conversion means 52. The frequency filter 532 removes a noise component in the electric signal. The A / D converter 533 converts an analog electric signal into a digital signal. The conversion means 534 performs calculation for adjustment according to the type of the oral pressure measuring pad connected to the distal end of the tube 4. Here, the volume, internal pressure, and repulsive force of the intraoral pressure measuring pad when an external pressure is applied differ depending on the shape and material of the intraoral pressure measuring pad connected to the tube 4. For this reason, even if the same external pressure is applied to different types of intraoral pressure measuring pads, the detected values of the internal pressure of the intraoral pressure measuring pads are different. On the other hand, the control means 53 performs calculation for adjustment according to the type of the intraoral pressure measurement pad, thereby processing the measurement information as an appropriate value regardless of the type of the intraoral pressure measurement pad. It becomes possible. Specifically, the conversion means 534 uses a conversion formula prepared in advance according to the type of the intraoral pressure measurement pad. This conversion formula is derived based on actually measured data. Examples of the types of pads for measuring the intraoral pressure include three types of pads for measuring the cheek pressure 2, the pad for measuring the tongue pressure 1, and the pad 3 for measuring the lip pressure. That is, the term “oral pressure measuring pad” is used as a general term for the cheek pressure measuring pad 2, the tongue pressure measuring pad 1, and the lip pressure measuring pad 3.

As shown in FIGS. 1 and 5, the operation means 54 is for making various inputs to the main body 5, for example, for resetting the on / off of the power source and the displayed measurement result of the intraoral pressure. Used for. The display means 55 displays various information such as the current value and maximum value (peak value) of the intraoral pressure. The storage unit 56 is a semiconductor memory, a hard disk, or the like, and stores and stores various information such as measurement information of intraoral pressure, for example.
The reset process is a function to accurately measure only the pressure applied to the intraoral pressure measurement pad, with the pressure value that is naturally applied when the intraoral pressure measurement pad is placed at the measurement location as the reference point (zero point). (Calibration function).

  The communication unit 57 is an interface for performing communication with the communication terminal 6. The communication method used in the communication unit 57 is Bluetooth (registered trademark) here, but is not limited to this, and may be other wireless communication or wired communication. As the wireless communication, for example, wireless LAN, ultrasonic communication, infrared communication, visible light communication, or the like can be used. For example, a wired LAN can be used as the wired communication.

  As shown in FIG. 1, the communication terminal 6 includes a display unit 61. Here, the communication terminal 6 is a smartphone, and the display unit 61 is a touch panel for displaying various information or performing various inputs. However, the communication terminal 6 may be a tablet PC or a notebook PC.

FIG. 7 is a diagram illustrating an example of a screen displayed on the display unit 61 of the communication terminal 6.
As shown in FIG. 7, the display unit 61 has a start button 611 for instructing the start of measurement, an end button 612 for instructing the end of measurement, and an intraoral pressure for designating the type of intraoral pressure to be measured. A type designation check box 613, an analog measurement result 614 showing the intraoral pressure in a graph, and a digital measurement result 615 showing the current value and the maximum value of the intraoral pressure are displayed. Here, time series data of the oral pressure measurement information from when the start button 611 is pressed to when the end button 612 is pressed, the maximum value (peak value), and the like can be stored in the storage unit 56.

Next, a method for measuring the intraoral pressure using the intraoral pressure measuring device 100 will be described.
First, a method for measuring the cheek pressure during swallowing will be described with reference to FIGS.
FIG. 8 is a diagram for explaining how the cheek pressure measuring pad 2 is inserted into the oral cavity. FIG. 9 is a diagram for explaining how the cheek pressure during swallowing is measured. 10 is a cross-sectional view taken along line XX of FIG.
In the case of measuring the cheek pressure during swallowing, water is prefilled from the water injection port 234 into the water injection bag 231 of the water injection means (wing part) 23 using a syringe or the like. The cheek pressure measuring pad 2 is connected to the distal end side of the tube 4 connected to the main body 5 (see FIGS. 1 and 2). At this time, in the intraoral pressure type designation check box 613 displayed on the display unit 61 of the communication terminal 6, the check box is checked in the “cheek pressure: left” or “cheek pressure: right” box (see FIG. 7). Thereafter, as shown in FIG. 8, the cheek pressure measuring pad 2 is inserted into the oral cavity. Then, as shown in FIGS. 9 to 10, the water injection means (wing part) 23 is the upper molar and the lower molar in the state where the hollow part 21 for measuring the buccal pressure is arranged between the cheek 103 and the molar part dentition 104.
