Description

The present invention relates to a training tool used for training the muscles of the oral cavity such as the tongue and the muscles of the face, and for confirming the effects of eating and swallowing rehabilitation, and particularly the effects of training. Etc. belongs to the technical field of the structure for confirming such as outside the oral cavity.

For example, when oral function declines due to aging, stroke, etc., the masticatory power and the force for swallowing decline, so when food or drink is swallowed, food etc. accidentally enters the trachea (hereinafter, This phenomenon is called "aspiration"). This aspiration may cause aspiration pneumonia. Aspiration pneumonia is the leading cause of death in the elderly, and preventing aspiration of patients and the elderly is an urgent issue.

Therefore, attempts have been made to improve the oral function by training the muscles related to the oral cavity for those who have a decreased swallowing function. Specifically, it is general to perform training for improving the muscular strength of the lips and tongue and the sophistication of their movements.

In this training, general-purpose items such as gauze and buttons are often processed and used according to the intention of the training and the level of the user, but in recent years, as a dedicated item to further enhance the effect of the training. The developed training equipment may be used (for example, refer to Patent Document 1).

The training device of Patent Document 1 includes a base portion to be inserted into the oral cavity, and a hollow bulging portion made of an elastic body formed so as to bulge from the base portion. A step is provided. Then, when the user pushes the tongue to crush the bulging portion after inserting the base into the oral cavity of the user, the stepped portion of the bulging portion elastically deforms when the force by the tongue exceeds a predetermined value. As a trigger for the start, the bulging part suddenly elastically deforms. At the moment when this sudden elastic deformation occurs, the bulging portion vibrates, and this vibration is transmitted to the tongue and hard palate, so that the user feels the vibration. In other words, when training, the user has to put his/her force on the tongue until vibration occurs, so it is clear how much force should be put during training to obtain the training effect, and Can be effectively performed.

JP, 2013-223702, A

By the way, it is important to confirm the effects of the eating and swallowing function and the eating and swallowing rehabilitation in order to grasp the level of the eating and swallowing function and to increase the motivation for rehabilitation. Examples of the confirmation method include a confirmation method using a tongue pressure measuring device used in medical institutions and the like, and a confirmation method using the instrument of Patent Document 1 described above. With the tongue pressure measuring device, the tongue pressure can be confirmed numerically, so it has the advantage that it can be grasped as an accurate value, but on the other hand, it is expensive because it incorporates a highly accurate sensor. There is a problem that it is difficult to popularize it.

Further, in the case of the confirmation method using the instrument of Patent Document 1, by preparing a plurality of types of instruments having different hardnesses of the bulging portion and determining which hardness of the bulging portion can be crushed, It is possible to grasp the strength of the tongue. However, for example, when the sensation in the oral cavity is paralyzed, it is not possible to feel the vibration that occurs when the bulging portion is deformed, and it is impossible to know whether or not the bulging portion can be crushed. There was a problem. Further, when the device of Patent Document 1 is used by a person whose sense in the oral cavity is paralyzed to perform training of the oral function, it is not known whether or not the bulging portion can be crushed. As a result, there was a problem in that it was not possible to get the feeling that he was training, leading to a decrease in motivation.

The present invention has been made in view of such a point, and the purpose thereof is to enable to obtain the feeling that the oral function training is performed outside the oral cavity, and to perform the oral function training. The purpose of the present invention is to make it possible to reliably and reliably confirm the effect outside the oral cavity.

In order to achieve the above object, in the present invention, it is possible to confirm the effect of training of oral function by utilizing the sense of the hand.

The first invention is
A pressure receiving portion that is made of an elastic material having a fluid filling portion that is filled with a fluid inside, is inserted into the oral cavity, and is elastically deformed by receiving an external force in the oral cavity,
A pressure transmission part having a contact part that is placed outside the oral cavity and is touched by the hand, while being made of an elastic material having a fluid filling part that is filled with a fluid inside,
It is characterized by comprising a tubular member that is in communication with the fluid filling portion of the pressure receiving portion and the fluid filling portion of the pressure transmitting portion and that is filled with fluid inside.

According to this configuration, when the user inserts the pressure receiving portion into the oral cavity and applies an external force to the pressure receiving portion by, for example, the force of the tongue, the pressure receiving portion is elastically deformed and crushed, so that the volume of the fluid filled portion of the pressure receiving portion. Becomes smaller. As the volume of the fluid filling portion of the pressure receiving portion changes, the fluid of the fluid filling portion flows into the tubular member and flows through the tubular member toward the pressure transmitting portion. As a result, the pressure transmitting portion elastically deforms in the direction in which the volume of the fluid filled portion of the pressure transmitting portion increases. At this time, the contact portion of the pressure transmitting portion is touched by the hand, and since the hand is a sensitive portion that can sense a minute change in shape, the above-mentioned elastic deformation of the pressure transmitting portion should be sensed by hand. Will be able to. At this time, for example, if the user's oral function level is high and the amount of deformation of the pressure receiving part is large, the amount of deformation of the pressure transmitting part is large, and conversely, the user's oral function level is low and the amount of deformation of the pressure receiving part is large. The smaller the value is, the smaller the deformation amount of the pressure transmitting portion is. Therefore, the level of the oral cavity related function level is shown in an easy-to-understand form as the deformation amount of the pressure transmitting portion.

Therefore, it becomes possible to confirm the effect of the eating and swallowing function level and the eating and swallowing rehabilitation with an inexpensive configuration without using a tongue pressure measuring device having an expensive sensor or the like, and for example, in the oral cavity. Even a person with paralyzed sensations can actually feel the training of oral function with the sense of the hands.

The second invention is the same as the first invention,
The contact portion of the pressure transmitting portion is provided with a mark portion serving as a mark.

According to this configuration, the contact portion of the pressure transmitting portion can be easily and accurately grasped, so that the portion touched by the hand does not vary from person to person. This makes it possible to accurately confirm the eating and swallowing function level and the effects of eating and swallowing rehabilitation.

3rd invention is a 2nd invention, Comprising:
The mark portion is a concave portion or a convex portion provided on the surface of the pressure transmitting portion.

With this configuration, the position of the contact portion can be easily determined, and the position of the finger can be easily determined by bringing the finger into contact with the concave portion or the convex portion, for example.

A fourth invention is the same as the second invention,
The mark portion is formed on the surface of the pressure transmitting portion and has a ring shape into which a finger is inserted.

According to this configuration, the position of the finger is easily determined by inserting the finger into the mark portion.

A fifth invention is the invention of any one of the first to fourth inventions,
The tubular member is provided with an adjusting valve for adjusting the internal pressure of the pressure receiving portion and the pressure transmitting portion.

According to this configuration, by injecting the fluid from the adjusting valve, the internal pressures of the pressure receiving portion and the pressure transmitting portion rise, and by discharging the fluid from the adjusting valve, the internal pressures of the pressure receiving portion and the pressure transmitting portion decrease. Therefore, the internal pressures of the pressure receiving portion and the pressure transmitting portion are arbitrarily changed depending on the injection amount and the discharge amount of the fluid. Thereby, for example, the internal pressures of the pressure receiving portion and the pressure transmitting portion are increased to suit the user having a high tongue pressure, and the internal pressures of the pressure receiving portion and the pressure transmitting portion are decreased to suit the user having a low tongue pressure. It will be possible.

A sixth invention is the invention according to any one of the first to fifth inventions,
The pressure receiving portion and the pressure transmitting portion are formed of balloons.

According to this structure, the pressure receiving portion and the pressure transmitting portion have a simple structure and are easily elastically deformed.

According to the first aspect of the present invention, the pressure receiving portion that is elastically deformed by receiving an external force inside the oral cavity and the pressure transmitting portion that has a contact portion that is placed outside the oral cavity and that is touched by the hand are connected by the tubular member. It is possible to obtain the feeling of being training outside the oral cavity, and at the same time, it is possible to reliably and reliably confirm the effect of training the oral function outside the oral cavity.

According to the second invention, since the mark portion is provided on the contact portion of the pressure transmitting portion, the contact portion can be grasped easily and accurately. As a result, the parts that are touched by the hands do not vary from person to person, so that the swallowing function level and the effect of swallowing rehabilitation can be accurately confirmed.

According to the third invention, since the concave portion or the convex portion formed on the surface of the pressure transmitting portion is used as the mark portion, the position of the contact portion can be easily discriminated and, for example, the finger contacts the concave portion or the convex portion. By doing so, the position of the finger is easily determined, and it is possible to prevent the portion touched by the hand from being varied depending on the person.

According to the fourth invention, since the finger can be inserted into the mark portion, the position of the finger can be easily determined, and it is possible to suppress the portion touched by the hand from being varied by a person.

According to the fifth invention, since the internal pressures of the pressure receiving portion and the pressure transmitting portion can be adjusted so as to match the oral cavity related function level of the user, the effect of the swallowing function level and the swallowing rehabilitation can be further improved. It can be confirmed more accurately.

According to the sixth aspect of the invention, the pressure receiving portion and the pressure transmitting portion can be easily configured to be elastically deformed while achieving cost reduction with a simple configuration, and the feeding and swallowing function level and the effect of feeding and swallowing rehabilitation can be accurately obtained. You can check.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely an example in essence, and is not intended to limit the present invention, its application, or its use.

In the present specification, the “vertical direction” is the direction in which the pressure receiving portion 2 is crushed by the user's tongue and hard palate when the pressure receiving portion 2 of the training device 1 for oral function is inserted into the oral cavity. Further, the “left-right direction” corresponds to the left-right direction of the user when the pressure receiving portion 2 of the training device 1 is inserted into the oral cavity.

FIG. 1 shows an oral function training device 1 according to a first embodiment of the present invention. The training device 1 is capable of performing training to train the muscles related to the oral cavity and the muscles of the face, and confirming the effects of the swallowing function level and the swallowing rehabilitation. Specifically, the training to train the muscles related to the oral cavity and the muscles of the face is a training whose main purpose is to improve the muscular strength of the lips and tongue and the sophistication of their movements. It is also possible to perform training for the purpose of improving cheek muscle strength. Moreover, since the muscle strength of the tongue is greatly involved in the eating and swallowing function, the eating and swallowing function level can be confirmed by confirming the muscle strength of the tongue. Furthermore, eating and swallowing rehabilitation is a rehabilitation mainly for improving the strength of the tongue, the muscles related to the oral cavity, and the muscles of the face. , The effect of eating and swallowing rehabilitation can be confirmed.

As a person who is a target of training using the training device 1 and a person who is a target of confirming the effects of the swallowing function level and the swallowing rehabilitation, for example, a person whose swallowing function is deteriorated due to a disease such as stroke. Examples include, but are not limited to, those whose swallowing function has deteriorated due to aging, and for example, those whose swallowing function has decreased, those who may decrease, etc. can be widely targeted. .. Further, the training device 1 according to the present embodiment can be applied to a person who has a particularly weak tongue force or a person who has a particularly poor skill in its operation. Furthermore, a person with a paralyzed sensation in the oral cavity can use the training device 1.

The training device 1 includes a pressure receiving portion 2, a grip portion 3, a pressure transmitting portion 4, a tubular member 5, and a regulating valve 6. The pressure receiving portion 2 can be formed of, for example, a balloon. Specifically, the pressure receiving portion 2 is made of an elastic material having a hollow fluid-filled portion 2a filled with a fluid, and is inserted into a user's oral cavity and elastically deformed by receiving an external force in the oral cavity. Is configured to. The pressure receiving portion 2 is formed so as not to allow the fluid to pass therethrough. Examples of the elastic material forming the pressure receiving portion 2 include at least one selected from the group consisting of silicone rubber, polypropylene, polyethylene, polyvinyl chloride, thermoplastic elastomer, natural rubber and the like, or a material obtained by mixing an arbitrary plurality thereof. However, the elastic material is not limited to these, and various elastic materials having a hardness range that can be elastically deformed when a force (external force) from the tongue is applied can be used. A preferable hardness range is 30 or more and 60 or less in Shore A (using a durometer). Further, it is preferable to use an elastomer which is inexpensive, has good moldability, and is highly safe for the human body.

The size of the pressure receiving portion 2 is set so that the entire pressure receiving portion 2 can be inserted into the oral cavity of the user, and can be changed according to the physique, age, and sex of the user. The pressure receiving portion 2 may have a spherical shape, but a flat shape is preferable. With the flat shape, the pressure receiving portion 2 can be stabilized, for example, on the tongue while the pressure receiving portion 2 is inserted into the oral cavity. Further, the pressure receiving portion 2 is set so that the dimension in the insertion direction into the oral cavity is longer than the dimension in the lateral direction.

The grip portion 3 is made of a material that is harder than the elastic material that forms the pressure receiving portion 2, and has a tubular shape. A passage 3 a is formed inside the grip 3. The passage 3a extends over both ends in the longitudinal direction of the grip 3. The grip portion 3 is fixed to one end portion in the longitudinal direction of the pressure receiving portion 2, and in a fixed state to the pressure receiving portion 2, one end portion of the passage 3 a of the grip portion 3 and the fluid filling portion 2 a of the pressure receiving portion 2 are connected. Has been done. The dimension of the grip portion 3 in the center line direction is set to be sufficiently longer than the dimension of the pressure receiving portion 2 in the longitudinal direction. Then, the grip portion 3 is arranged so as to project from the lip to the outside of the oral cavity in a state where the pressure receiving portion 2 is inserted into the oral cavity. In this state, the user can hold the grip portion 3 by hand, and the grip portion 3 can be held by being bitten by the upper and lower front teeth. Therefore, the grip portion 3 has such a rigidity that it is not deformed when it is held by hand or bitten by the front teeth.

A cylindrical connecting portion 3b is provided on the opposite side of the grip portion 3 to the pressure receiving portion 2. The passage 3a is formed inside the connecting portion 3b, and the passage 3a is open at the end of the connecting portion 3b. One end of the tubular member 5 is connected to the connecting portion 3b, so that the tubular member 5 and the fluid filling portion 2a of the pressure receiving portion 2 communicate with each other.

The pressure transmitting portion 4 can be formed of a balloon or the like made of the same material as that of the pressure receiving portion 2. Specifically, the pressure transmission part 4 is a part which is made of an elastic material having a hollow fluid-filled part 4a in which the fluid is filled and which is placed outside the oral cavity. The pressure transmitting portion 4 may have a spherical shape, but a flat shape is preferable. By having a flat shape, a curved surface having a large curvature and a curved surface having a small curvature can be formed on the outer surface of the pressure transmitting portion 4, and the pressure transmitting portion 4 must be provided so that the curved surface having a large curvature can be touched by the hand. Thus, the pressure transmission section 4 can be stabilized. Further, the shape of the pressure transmitting portion 4 may be any shape such as an elongated rod shape, a plate shape, a pyramid shape, a conical shape, or the like.

Since the pressure transmitting portion 4 has the flat shape as described above, curved surfaces having large curvatures are formed on the outer surface of the pressure transmitting portion 4 on both sides in the thickness direction of the pressure transmitting portion 4. In this embodiment, the curved surfaces having large curvatures on the outer surface of the pressure transmitting portion 4 become the first contact surface (contact portion) 4b and the second contact surface (contact portion) 4c which are touched by the user's hand, respectively. ing. Therefore, the first contact surface 4b and the second contact surface 4c are formed on both sides of the pressure transmitting portion 4 in the thickness direction.

The tubular member 5 can be formed of a flexible resin tube or the like. The other end of the tubular member 5 is connected to one end of the pressure transmitting portion 4 in the longitudinal direction, and the tubular member 5 and the fluid filling portion 4a of the pressure transmitting portion 4 communicate with each other.

The material forming the tubular member 5 is less likely to be deformed than the pressure receiving portion 2 and the pressure transmitting portion 4, and the diameter of the tubular member 5 hardly changes when the pressure receiving portion 2 is crushed and the internal pressure rises. I am trying. The length of the tubular member 5 can be set, for example, in the range of several tens of cm to 100 cm, but is not limited to this range, and the pressure transmitting unit 4 is inserted with the pressure receiving unit 2 inserted in the oral cavity. It only needs to be long enough to be held by hand. The tubular member 5 is also filled with the fluid.

The adjusting valve 6 is for adjusting the internal pressure of the pressure receiving portion 2 and the pressure transmitting portion 4, that is, the internal pressure of the fluid filling portion 2a and the fluid filling portion 4a. Specifically, the adjusting valve 6 can be configured by, for example, a well-known check valve or the like used in a medical field, and a syringe (not shown) or the like is connected to the adjusting valve 6 so that It is possible to inject the above fluid into the tubular member 5 and allow the fluid inside the tubular member 5 to flow into the syringe. By injecting the fluid in the syringe into the tubular member 5, the internal pressure of the pressure receiving portion 2 and the pressure transmitting portion 4 increases. On the other hand, by causing the fluid in the tubular member 5 to flow into the syringe, the internal pressures of the pressure receiving portion 2 and the pressure transmitting portion 4 decrease. The amount of the fluid to be injected into the tubular member 5 and the amount of the fluid in the tubular member 5 to flow into the syringe can be set arbitrarily. The adjusting valve 6 may be omitted.

Next, a method of using the training device 1 configured as described above will be described. The user inserts the pressure receiving unit 2 into the oral cavity and holds the pressure transmitting unit 4 outside the oral cavity by hand. At this time, the user brings the index finger 100 into contact with the first contact surface 4b of the pressure transmitting portion 4 and the thumb 101 into contact with the second contact surface 4c of the pressure transmitting portion 4, as shown in FIG. The part 4 is held by being sandwiched between the index finger 100 and the thumb 101. Note that any finger may be brought into contact with the first contact surface 4b and the second contact surface 4c. Further, both hands may be brought into contact with the first contact surface 4b and the second contact surface 4c.

The user stops insertion of the pressure receiving portion 2 with the pressure receiving portion 2 placed on the tongue, and holds the grip portion 3 by hand. At this time, the grip portion 3 may be bitten by the upper and lower front teeth. Then, the user applies force to the tongue to push it up. Then, the pressure receiving portion 2 is sandwiched between the tongue and the hard palate, and an external force acts on the pressure receiving portion 2 so as to crush it in the vertical direction.

Further, it is preferable that the fluid filling portion 2a of the pressure receiving portion 2, the fluid filling portion 4a of the pressure transmitting portion 4 and the tubular member 5 are filled with air, but various gases other than air and liquids such as water are filled. You may do so.

When the pressure receiving portion 2 is crushed, the volume of the fluid filling portion 2a of the pressure receiving portion 2 becomes small. As the volume of the fluid filling portion 2a of the pressure receiving portion 2 changes, the fluid of the fluid filling portion 2a flows into the tubular member 5 and flows through the tubular member 5 toward the pressure transmitting portion 4. As a result, the fluid in the tubular member 5 flows into the fluid filling portion 4a of the pressure transmitting portion 4 and the pressure transmitting portion 4 elastically deforms in a direction in which the volume of the fluid filling portion 4a increases. At this time, the first contact surface 4b and the second contact surface 4c are touched by the hand, and since the hand is a sensitive portion where even a slight change in shape can be sensed, the elasticity of the pressure transmitting portion 4 described above is obtained. You will be able to feel the deformation by hand. For example, if the user's mouth-related function level is high and the deformation amount of the pressure receiving portion 2 is large, the deformation amount of the pressure transmitting portion 4 is large, and conversely, the user's mouth-related function level is low and the deformation amount of the pressure receiving portion 2 is large. Since the deformation amount of the pressure transmitting unit 4 is small when is smaller, the level of the oral cavity-related function level is shown in an easy-to-understand form as the deformation amount of the pressure transmitting unit 4. By repeating the exercise of raising and lowering the tongue, it becomes a training of oral function.

Therefore, according to this embodiment, it is possible to confirm the effects of the swallowing function level and the swallowing rehabilitation with an inexpensive configuration without using a tongue pressure measuring device having an expensive sensor or the like. In addition, for example, even a person with paralyzed sensation in the oral cavity can obtain the actual feeling of training the oral function with the sense of hand.

Moreover, since the adjusting valve 6 is provided, the internal pressures of the pressure receiving portion 2 and the pressure transmitting portion 4 can be arbitrarily changed. Thereby, for example, the internal pressure of the pressure receiving portion 2 and the pressure transmitting portion 4 is increased to suit a user having a high tongue pressure, and the internal pressure of the pressure receiving portion 2 and the pressure transmitting portion 4 is adjusted to suit a user having a low tongue pressure. It is possible to reduce the pressure. Therefore, the swallowing function level and the effect of swallowing rehabilitation can be more accurately confirmed.

Further, since it is possible to train the muscles around the oral cavity, it is possible to obtain the cosmetic effect of tightening the face.

It is also possible to perform training by pushing the pressure receiving portion 2 with the tip of the tongue.

In addition, the pressure receiving portion 2 is disposed between the side surface of the back tooth and the inner surface of the cheek with the upper and lower teeth engaged with each other, and the pressure receiving portion 2 is pressed against the back tooth by the muscle of the cheek so that the pressure receiving portion 2 is elastic. It may be deformed.

Further, the pressure receiving portion 2 may be sandwiched between the upper lip and the lower lip and crushed vertically by the lips.

Further, in the above-described embodiment, the case where the first contact surface 4b and the second contact surface 4c are configured by smooth surfaces has been described. ,
The first contact surface 4b may be provided with three first convex portions 4d, 4d, 4d as a mark portion that serves as a mark of the first contact surface 4b. The first protrusions 4d, 4d, 4d are formed of protrusions extending in the longitudinal direction of the pressure transmitting portion 4, and extend substantially in parallel with each other with a space therebetween. Further, the second contact surface 4c is also provided with three second convex portions 4e, 4e, 4e as mark portions that serve as marks of the second contact surface 4c. The 2nd convex parts 4e, 4e, and 4e are comprised by the ridge extended in the longitudinal direction of the pressure transmission part 4, and are mutually extended, and are extended in substantially parallel. The first convex portion 4d and the second convex portion 4e may extend in a direction intersecting the longitudinal direction of the pressure transmitting portion 4.

Further, one of the first convex portion 4d and the second convex portion 4e may be omitted. Further, the shapes of the first convex portion 4d and the second convex portion 4e may be changed, and by doing so, the front and back of the pressure transmitting portion 4 can be clearly recognized.

The number of the first convex portions 4d and the second convex portions 4e is not limited to three, and may be two or less or four or more. When a plurality of first convex portions 4d and a plurality of second convex portions 4e are provided, the first convex portions 4d may intersect with each other and the second convex portions 4e may intersect with each other. Further, the first convex portion 4d and the second convex portion 4e may be dot-shaped convex portions. Although not shown, a concave portion may be provided instead of the first convex portion 4d and the second convex portion 4e. The recess may be a groove or a dimple shape. Although not shown, the first contact surface 4b and the second contact surface 4c may be provided with both a convex portion and a concave portion, respectively.

Further, as in the second modification shown in FIG. 4, the first contact surface 4b may be provided with the first recess 4f and the second contact surface 4c may be provided with the second recess 4g. Since the fingers are fitted into the first concave portions 4f and the second concave portions 4g, the positions of the fingers can be easily fixed and the pressure transmitting portion 4 is stabilized.

In the modified examples 1 and 2, the contact surfaces 4b and 4c of the pressure transmitting portion 4 can be easily and accurately grasped, and therefore, the portions to be touched by hands do not vary from person to person. This makes it possible to accurately confirm the eating and swallowing function level and the effects of eating and swallowing rehabilitation. Further, the first convex portion 4d may be formed on the first contact surface 4b and the second concave portion 4g may be formed on the second contact surface 4c. On the contrary, you may form the 1st recessed part 4f in the 1st contact surface 4b, and may form the 2nd convex part 4e in the 2nd contact surface 4c.

Further, as in Modification 3 shown in FIG. 5, the surface of the pressure transmitting portion 4 may be provided with first and second finger inserting portions 7 and 8 formed in a ring shape into which fingers are inserted. The first finger inserting portion 7 is provided on the first contact surface 4b, and the second finger inserting portion 8 is provided on the second contact surface 4c. As shown by the phantom line, the finger 100 is inserted into the first finger insertion portion 7 to contact the first contact surface 4b, and the finger 102 is inserted into the second finger insertion portion 8 to contact the second contact surface 4c. As a result, the positions of the fingers 100 and 102 are easily determined.

Further, the volume of the fluid filling portion 2a of the pressure receiving portion 2 and the volume of the fluid filling portion 4a of the pressure transmitting portion 4 may be the same, or one volume may be larger than the other volume.

The above embodiments are merely examples in all respects, and should not be construed in a limited manner. Further, all modifications and changes belonging to the equivalent range of the claims are within the scope of the present invention.

As described above, the device for training oral function according to the present invention can be used to train the muscles of the oral cavity such as the tongue and the muscles of the face.
