Description

Oral-related function judgment device

The present invention relates to an oral cavity related function determination device used when determining oral cavity related functions including a tongue.

For example, if oral-related functions decline due to aging or illness such as stroke, the ability to chew and swallow will decline, so if you swallow food or drink in the mouth, The phenomenon of entering (hereinafter, this phenomenon is referred to as aspiration) is likely to occur. It is also known that this aspiration may cause aspiration pneumonia.

In recent years, in order to improve QOL (Quality of Life) of elderly people, maintenance and recovery of feeding and swallowing functions are required, and it is necessary to clarify the functions. The movement of the tongue is deeply involved in the eating and swallowing functions, and a predetermined tongue pressure is required for the formation of the bolus and the feeding into the pharynx. For this reason, the measurement and analysis of tongue pressure as one of the oral-related functions are important.

Some methods for measuring tongue pressure are known, and for example, those disclosed in Patent Documents 1 and 2 are actually used in clinical practice. The oral cavity related pressure measuring device disclosed in Patent Document 1 uses a probe provided with a balloon. After the balloon is inserted into the oral cavity, when the balloon is pressed with the tongue, the pressure detection unit communicating with the balloon detects a change in the air pressure in the balloon, and the tongue pressure can be measured by converting it into an electrical signal. . In the measuring apparatus disclosed in Patent Document 1, the probe is positioned so that the hard ring attached to the probe is positioned at the lips or teeth.

The measuring device disclosed in Patent Document 2 includes a pressure sensor sheet having a pressure detection cell. With the pressure sensor sheet affixed to the palate, a series of tongue movements can be detected as an electrical signal by the pressure sensor sheet by actually chewing and swallowing food.

According to this configuration, when determining the oral function, the insertion part is inserted into the oral cavity, and force is applied to the insertion part, for example, by a muscle that moves the tongue. If the force applied to the insertion portion is greater than or equal to a predetermined level and is strong enough to prevent swallowing or the like in terms of oral function, the bent portion of the base portion bends. On the other hand, when the force applied to the insertion portion is weaker than a predetermined value and there is a problem in swallowing or the like in terms of oral cavity-related functions, the bent portion does not bend. Therefore, it is possible to determine whether there is a problem in the oral-related function in a manner that anyone can easily and reliably recognize the bending deformation of the bent portion. Can be done easily.

According to a second invention, in the first invention,
The bent portion has a groove portion formed in the base portion.

According to this configuration, the bent portion can be realized with a simple configuration, and the base portion can be reliably bent when the force applied to the insertion portion is greater than or equal to a predetermined value.

According to a third invention, in the first invention,
The base portion is provided with a grip portion to be gripped by hand.

According to this configuration, the base is sandwiched by at least one of the teeth and the lips and is grasped by hand, so that the insertion portion can be easily positioned in the oral cavity and an accurate determination result can be obtained. .

The fourth invention is:
In the oral-related function determination device for determining the oral-related function,
An insertion part that is inserted into the oral cavity when determining oral-related functions;
A base extending from the insertion portion to the outside of the oral cavity and sandwiched by at least one of a tooth and a lip;
The insertion portion is configured to be plastically deformed when a force applied to the insertion portion in the oral cavity is equal to or greater than a predetermined value.

According to this configuration, when determining the oral function, the insertion part is inserted into the oral cavity, and force is applied to the insertion part, for example, by a muscle that moves the tongue. If the force applied to the insertion portion is greater than or equal to a predetermined level and is strong enough to prevent swallowing or the like in terms of oral cavity-related functions, the insertion portion is plastically deformed. On the other hand, when the force applied to the insertion portion is weaker than a predetermined value and there is a problem with swallowing or the like in terms of oral function, plastic deformation does not occur. Therefore, it is possible to determine whether there is a problem in the oral-related function in a manner that anyone can easily and reliably recognize the plastic deformation of the insertion portion. Can be done easily.

A fifth invention is the fourth invention,
The insertion portion has a bulging portion that is curved so as to bulge in a direction in which a force is applied, and the bulging portion is configured to be plastically deformed.

According to this configuration, for example, it is possible to plastically deform the bulge by applying a force so as to crush the bulge with a tongue. At this time, since the bulging portion is curved, the feeling of use is improved without giving pain or discomfort to the person to be judged.

According to a sixth invention, in the fifth invention,

It should be noted that the following description of the preferred embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

In the present specification, the “vertical direction” refers to the tongue and hard palate of the person to be determined (user) when the oral cavity related function determination device 1 of the present invention is inserted into the oral cavity as shown in FIG. It is a direction to push an insertion portion described later, and the “left / right direction” corresponds to the left / right direction of the person to be determined when the oral cavity related function determination device 1 is inserted into the oral cavity.

(Embodiment 1)
FIG. 1 shows an oral cavity related function determination device 1 according to Embodiment 1 of the present invention. The mouth-related function determination device 1 is for determining a mouth-related function. Specifically, the mouth-related muscle strength, in particular, the strength of the muscle that moves the tongue, can be used without any problem in chewing and swallowing. It can be used to determine if it is at a level that can be done. As the function related to the oral cavity, for example, it can be used to determine the muscular strength of the lips and the sophistication of the operation of the tongue and lips.

Examples of the person to be determined using the oral-related function determination device 1 include a person whose swallowing function has decreased due to a disease such as stroke, a person whose swallowing function has decreased due to aging, and the like. For example, a person who has a reduced swallowing function or a person who is likely to decrease can be widely determined.

As shown in FIG. 3, the oral cavity related function determination instrument 1 includes an insertion portion 10 that is inserted into the determination subject's oral cavity when the oral cavity related function is determined, and a base 20 that extends so as to extend from the insertion portion 10. I have. Examples of the material for the insertion portion 10 and the base portion 20 include, but are not limited to, polypropylene, polyethylene, polyvinyl chloride, and the like, and the extent that the mucous membrane in the oral cavity cannot be damaged when inserted into the oral cavity. A soft material having the following hardness is preferred. In addition, it is preferable to use a material that is inexpensive, has good moldability, and has high safety to the human body.

The material of the insertion portion 10 and the base portion 20 may be different materials. By making the material of the base part 20 harder than the material of the insertion part 10, the base part 20 can be firmly fixed at the time of use mentioned later.

As shown in FIG. 1 and FIG. 4, the insertion portion 10 is formed to bulge downward, that is, to the lingual side in the use state shown in FIG. 2, and is composed of a smooth curved surface as a whole. Thereby, when a tongue etc. touch the insertion part 10, it is made not to give pain. The shape of the insertion portion 10 is not limited to the curved shape described above, and may be, for example, a flat plate shape.

The base portion 20 is provided integrally with the insertion portion 10 and extends outside the oral cavity in a state where the insertion portion 10 is inserted into the oral cavity, and constitutes a portion that is sandwiched between at least one of the teeth and lips of the person to be determined. is doing. Specifically, the base 20 is formed in a plate shape. The width (dimension in the left-right direction) of the base 20 is set to, for example, 20 mm to 30 mm, and the length is set to 80 mm to 90 mm. However, these dimensions are only examples, and are matched to the gender and physique of the person to be judged. Can be changed.

As shown in FIG. 2, in the use state of the oral cavity related function determination instrument 1, one side in the longitudinal direction of the base 20 is inserted into the oral cavity, and the other side goes out of the oral cavity. As shown in FIG. 3, the edge part of the longitudinal direction one side (right side of FIG. 3) of the base 20 is formed in circular arc shape. This is a shape along the outer edge of the insertion portion 10. Moreover, the edge part of the other side (left side of FIG. 3) of the base 20 is also formed in circular arc shape.

As shown in FIG. 1, a plurality of upper ridges 21 a are formed on the upper surface 21 of the base 20. Each upper ridge portion 21a extends in the width direction of the base portion 20, and is gently curved so as to form an arc in a plan view. The arc shape of the upper ridge portion 21a corresponds to, for example, a sequence of adult front teeth A and B (shown in FIG. 2). The upper ridges 21 a are arranged at intervals in the longitudinal direction of the base 20. An upper groove 21b is formed between the upper ridges 21a adjacent to each other in the longitudinal direction of the base 20. Although details will be described later, the upper groove 21b is for fitting the upper front tooth A of the determination subject.

As shown in FIG. 3, a plurality of lower ridges 22 a are also formed on the lower surface 22 of the base 20. The number of the lower ridges 22a is larger than that of the upper ridges 21a, and the formation of the lower ridges 22a on the lower surface of the base 20 is greater than the formation range of the upper ridges 21a on the upper surface of the base 20. The range is wider.

The lower ridge 22a has substantially the same curvature as the upper ridge 21a, and the lower ridge 22a is longer than the upper ridge 21a. A plurality of lower grooves 22b are also formed on the lower surface 22 of the base portion 20 by the formation of the lower ridge portions 22a. Although details will be described later, the lower groove 22b is for fitting the lower front tooth B of the person to be determined.

The upper ridge portion 21 a and the lower ridge portion 22 a are arranged so as to be shifted from each other in the longitudinal direction of the base portion 20. That is, the lower ridge 22a is not positioned directly below the upper ridge 21a. Accordingly, the upper groove 21b and the lower groove 22b are also displaced from each other in the longitudinal direction of the base portion 20. The shift amount between the upper groove 21b and the lower groove 22b is set in consideration of the shift amount in the front-rear direction between the upper end of the upper front tooth A and the upper end of the lower front tooth B of a general adult. It can be set to ~ 2 mm. The shift amount between the upper groove 21b and the lower groove 22b is an amount corresponding to the shift amount in the front-rear direction between the lower end of the upper front tooth A and the upper end of the lower front tooth B.

As shown in FIG. 4, on one side in the longitudinal direction of the base portion 20, a through hole 23 that penetrates in the vertical direction (thickness direction of the base portion 20) is formed in a portion corresponding to the insertion portion 10. The through hole 23 is circular and communicates with the hollow portion R of the insertion portion 10. By forming the through hole 23, the hollow portion R is opened. A line indicated by a symbol S in FIG. 4 is a center line of the through hole 23.

As shown in FIG. 3, a circular through hole 24 is formed at the end of the base 20 opposite to the side where the insertion portion 10 is formed. The through-hole 24 is for hooking through a hook or the like when storing the oral cavity related function determination device 1, or for allowing a person to be determined to hold the oral cavity related function determination device 1 through a finger. . Further, the side of the base 20 where the insertion hole 24 is formed is a grip portion 29 that is gripped by hand.

The base portion 20 is added to the insertion portion 10 in the oral cavity between the insertion portion 10 and the portion sandwiched by at least one of the teeth and the lips (the portion where the upper groove 21b and the lower groove 22b are formed). A bent portion 27 is provided that bends when the applied force is greater than or equal to a predetermined value. The bent portion 27 is bent in a direction in which the insertion portion 10 is moved upward in the use state shown in FIG.

In this embodiment, the bent portion 27 has a groove portion 27 a formed on the lower surface of the base portion 20. The groove 27 a extends in the width direction of the base 20. By changing at least one of the depth, length, and width of the groove portion 27a, the force when the bent portion 27 starts to be bent can be arbitrarily changed. In addition, the groove part 27a may be formed continuously in the width direction of the base part 20, or may be formed intermittently. Moreover, you may form a recessed part, a hole, etc., for example instead of the groove part 27a or with the groove part 27a. That is, it is preferable to provide the bent portion 27 with a configuration that makes the bent portion 27 easier to bend than other portions of the base portion 20.

When the force applied to the insertion portion 10 in the oral cavity is a predetermined value or more, the bending portion 27 is bent and the insertion portion 10 is moved upward. The force applied to the insertion portion 10 in the oral cavity is due to the muscle strength in the oral cavity of the person to be determined. If the muscle strength in the oral cavity is strong, the force applied to the insertion portion 10 in the oral cavity becomes strong. In this embodiment, the force applied to the insertion portion 10 in the oral cavity is greater than or equal to a predetermined value because the force can be applied by a person to be judged having a level of muscular strength that allows chewing and swallowing without problems in a normal meal. That is.

In addition, as described above, the criterion for determining the force applied in the oral cavity to the insertion unit 10 may be based on whether or not it has a level of muscular strength that allows chewing and swallowing without problems in a normal meal. Not limited to this, it may be set to a lower level depending on the age and illness condition, and may be a standard that can determine the degree of ability recovery by mastication or swallowing rehabilitation.

The base 20 is preferably made of a plastically deformable material. As a result, once the bent portion 27 is bent, it does not return to its original shape, so that it is possible to clearly recognize that it has been bent. In addition, when the bent portion 27 is bent once, the bent mark remains on the upper surface 21 of the base portion 20 as a line. This also makes it possible to clearly recognize the bending. Further, the bent portion 27 is not separated from the base portion 20 after being bent. Thereby, since the insertion part 10 does not drop from the base part 20, safety is enhanced.

Next, the case where the oral cavity related function determination device 1 configured as described above is used will be described. First, as shown in FIG. 2, the insertion portion 10 side of the base 20 is inserted into the oral cavity of the person to be judged, and when the insertion portion 10 reaches the tongue, further insertion is stopped. In this state, the other end portion in the longitudinal direction of the base portion 20 protrudes from the oral cavity. At this time, since the upper groove 21b and the lower groove 22b are formed in the base portion 20 so as to be easily bent and deformed, the base portion 20 can be deformed so as to correspond to the shape of the oral cavity.

Then, the person to be judged bites the base 20 with the front teeth A and B. Then, the upper front tooth A fits into the upper groove 21b, and the lower front tooth B fits into the lower groove 22b. At this time, the upper groove 21b and the lower groove 22b are curved so as to correspond to the upper front teeth A and the lower front teeth B, respectively, so that the person to be judged only needs to naturally bite the base 20 and the front teeth A , B are surely fitted in both

grooves

21b, 22b. Further, generally, the lower end of the upper front tooth A of the person to be judged and the upper end of the lower front tooth B are displaced in the front-rear direction. In this embodiment, the upper groove 21b and the lower groove 22b are arranged in front of and behind the person to be judged. Since it is shifted in the direction, this also ensures that the front teeth A and B fit into the

grooves

21b and 22b only by the person to be judged naturally biting the base 20. As a result, the base 20 is stably fixed to the person to be determined. Moreover, the grip part 29 of the base 20 is gripped by hand as necessary. The person holding the object may be a person to be measured or another person.

In a state where the insertion part 10 is inserted into the oral cavity, the base part 20 is separated downward from the palate so that the base part 20 does not touch the palate.

Moreover, when adjusting the position of the insertion part 10 in the insertion direction in the oral cavity, the base part 20 may be taken in and out. In this case, the base part 20 is provided with a plurality of upper grooves 21b and lower grooves 22b. Even after the position adjustment, the front teeth A and B are surely fitted into the grooves 11b and 12b only by biting the base 20. Therefore, for example, even if the same oral cavity related function determination instrument 1 is used by a plurality of determination persons having different genders, physiques, and the like, the insertion portion 10 can be disposed at a position suitable for each.

After that, the person to be measured applies force to push up the tongue. Since the tongue is in contact with the insertion portion 10, an upward force is applied to the insertion portion 10. At this time, since the insertion portion 10 side of the base 20 is separated downward from the palate, when the force applied to the insertion portion 10 in the oral cavity is greater than or equal to a predetermined value, swallowing or the like in terms of oral-related functions That is, the strength has no problem. In this case, the bent portion 27 is bent. Thereby, as shown in FIG. 5, the insertion part 10 moves upwards. As the insertion unit 10 moves upward, the person to be determined can know the determination result himself.

On the other hand, when the force applied to the insertion portion 10 in the oral cavity is weaker than a predetermined value, there is a problem with swallowing or the like in terms of oral-related functions. Since it does not bend, the insertion part 10 does not move.

As described above, according to the oral cavity related function determination device 1 according to the first embodiment, anyone can easily determine whether there is a problem in the oral cavity related function, that is, bending deformation of the bent portion 27, and Since it can be determined in such a manner that it can be reliably recognized, anyone can easily determine the oral-related function even if it is not a professional.

Also, the base 20 can be clamped by at least one of teeth and lips. Since the base portion 20 is provided, the insertion portion 10 can be stabilized when a force is applied to the insertion portion 10 in the oral cavity, and an accurate determination result can be obtained.

Further, in the first embodiment, a plurality of oral-related function determination devices 1 having different forces required to bend the bending portion 27 may be prepared and set as a set. Thereby, when the to-be-measured person's oral-related muscular strength is weaker than predetermined, it can be determined concretely.

(Embodiment 2)
6 to 8 show an oral cavity related function determination device 1 according to Embodiment 2 of the present invention. The oral cavity related function determination instrument 1 according to the second embodiment differs from that according to the first embodiment in that the insertion portion 10 is plastically deformed and the base portion 20 is not provided with a bent portion. Yes. Hereinafter, the same parts as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and the description thereof will be omitted. The parts different from those of the first embodiment will be described in detail.

Since the base portion 20 of the second embodiment is not provided with a bent portion, the base portion 20 does not bend even when a predetermined force or more is applied to the insertion portion 10 in the oral cavity.

The insertion part 10 of Embodiment 2 is configured to be plastically deformed and crushed when the force applied to the insertion part 10 in the oral cavity is equal to or greater than a predetermined value. That is, the insertion part 10 is comprised with the material which deforms plastically, As the material, resin is preferable, for example.

The insertion part 10 has a fixed part 13 that is fixed to the lower surface 21 of the base part 20 and a bulging part 14 that is curved so as to bulge in the direction in which force is applied (downward). The fixing portion 13 is configured by a protruding portion that protrudes downward from the peripheral portion of the through hole 23 of the base portion 20 and continuously extends in the circumferential direction of the through hole 23. The bulging portion 14 bulges from the lower edge portion of the fixed portion 13. The bulging part 14 is formed thinner than the fixed part 13, and the bulging part 14 is crushed and deformed. The force at which the bulging portion 14 starts to be crushed can be arbitrarily set depending on the thickness of the bulging portion 14, the resin hardness, the shape (degree of bending) of the bulging portion 14, and the like. The bulging portion 14 is crushed and deformed by the force when 27 is bent.

Next, the case where the oral cavity related function determination device 1 configured as described above is used will be described. First, the insertion portion 10 side of the base portion 20 is inserted into the determination subject's mouth, and when the insertion portion 10 reaches the tongue, further insertion is stopped. At this time, the insertion portion 10 side of the base portion 20 is kept in contact with the palate. The person to be judged bites the base 20 with the front teeth A and B. Moreover, the grip part 29 of the base 20 is gripped by hand as necessary.

After that, the person to be measured applies force to push up the tongue. Since the tongue is in contact with the insertion portion 10 and the insertion portion 10 side of the base portion 20 is in contact with the palate, a force in the direction of crushing is applied to the insertion portion 10. If the force applied to the insertion portion 10 in the oral cavity is greater than or equal to a predetermined value, it means that the strength is such that there is no problem in swallowing or the like in terms of oral functions. In this case, FIG. As shown, the bulging portion 14 of the insertion portion 10 is crushed. Thereby, the person to be determined can know the determination result himself. Even if the external force is removed after the bulging portion 14 is crushed, the bulging portion 14 does not return to its original shape because it is plastically deformed. Therefore, other persons can also grasp the collapse state of the bulging portion 14 by visual observation. Moreover, even if it tries to return the shape of the bulging part 14 to the original shape, it does not return completely, but the crushed trace remains as unevenness.

On the other hand, when the force applied to the insertion portion 10 in the oral cavity is weaker than a predetermined value, there is a problem in swallowing or the like in terms of oral-related functions. In this case, the bulging portion 14 Does not plastically deform.

As described above, according to the oral cavity-related function determination device 1 according to the second embodiment, whether or not there is a problem on the oral cavity-related function can be easily determined by anyone, plastic deformation of the bulging portion 14, And since it can determine in the aspect which can be recognized reliably, even if it is not a professional, anyone can determine an oral cavity related function easily.

In addition, in Embodiment 2, although the fixing | fixed part 13 and the bulging part 14 of the insertion part 10 are made into different thickness, it is good not only in this but in the same thickness.

Further, in the second embodiment, a plurality of oral-related function determination devices 1 having different forces required for plastic deformation of the bulging portion 14 may be prepared and set. Thereby, when the to-be-measured person's oral-related muscular strength is weaker than predetermined, it can be determined concretely.

Moreover, in Embodiment 1, 2, since one part of the oral cavity related function determination instrument 1 is plastically deformed, once used, the oral cavity related function determination instrument 1 is erroneously used for another person. Absent. Therefore, safety is high and hygiene is also good.

The above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

As described above, the oral cavity related function determination device according to the present invention can be used, for example, when determining oral muscle related muscle strength.
