Description

本発明は、舌の挙上をはじめ口腔の運動機能の改善による嚥下機能等の回復や嚥下動作の補助を目的として用いられる口腔リハビリ器具に関する。   The present invention relates to an oral rehabilitation device used for the purpose of recovery of the swallowing function and the like by improvement of the motor function of the oral cavity including elevation of the tongue and assisting in the swallowing operation.

嚥下は、舌の運動により食物や飲物を上顎の軟口蓋に押し付けて、口腔から咽頭に送る口腔期と、喉頭蓋が下がることにより気道を閉鎖して、食べ物等を咽頭から食道に送る咽頭期と、食物等を食道の蠕動運動により胃まで送る食道期とに分けられる。嚥下障害とは、種々の原因により嚥下の機能が損なわれることである。嚥下障害になると食物等を摂取できなくなったり、誤って食物等が気道に入ったりすることにより、例えば誤嚥性肺炎を誘発したりする場合がある。   In swallowing, the tongue moves the food and drink into the upper palate by pushing food and drink to the maxilla, and the pharyngeal phase, which moves the food from the pharynx to the esophagus by closing the airway by lowering the epiglottis. It is divided into the esophagus stage which sends food etc. to the stomach by peristaltic movement of the esophagus. Dysphagia is the loss of the function of swallowing due to various causes. When it becomes dysphagia, food and the like can not be ingested, and food and the like may enter the airway by mistake, for example, aspiration pneumonia may be induced.

嚥下障害の一因としては、加齢に伴う舌の運動機能の低下や咀嚼機能の低下が挙げられる。そこで、従来より、嚥下障害者の嚥下を促すとともに、嚥下に使用される筋力の訓練を行なうことができる嚥下訓練用の口腔リハビリ器具が提案されている。その一例として、内部に流体が充填される流体充填部を有し、口腔内に挿入されて口腔内で外力を受けて弾性変形する受圧部と、内部に流体が充填される流体充填部を有し、口腔外に配置されて手が触れる接触部を有する圧力伝達部と、受圧部の流体充填部と圧力伝達部の流体充填部とを連通する管状部材とを備える嚥下訓練器具が提案されている(特許文献1)。かかる口腔リハビリ器具は、被訓練者が受圧部を口腔内に挿入して舌の力によって受圧部に外力を加えると、受圧部が弾性変形して押し潰され、流体が管状部材から圧力伝達部の流体充填部に流入して流体充填部の容積が拡大し、この弾性変形を手で感じ取ることにより、嚥下訓練をしているという実感を手の感覚で得ることができるというものである。   One of the causes of dysphagia is a decrease in motor function and a decrease in masticatory function with aging. Therefore, conventionally, an oral rehabilitation device for swallowing training has been proposed which promotes swallowing of dysphagia persons and can perform muscle strength training used for swallowing. As an example, it has a fluid filling part filled with fluid inside, and has a pressure receiving part inserted into the oral cavity and elastically deformed in the oral cavity under external force, and a fluid filling part filled inside with fluid. Proposed is a swallow training tool comprising a pressure transmitting part disposed outside the oral cavity and having a hand touching part, and a tubular member communicating the fluid filling part of the pressure receiving part and the fluid filling part of the pressure transmission part. (Patent Document 1). In such an oral rehabilitation device, when the trainee inserts the pressure receiving portion into the oral cavity and applies an external force to the pressure receiving portion by the force of the tongue, the pressure receiving portion is elastically deformed and crushed, and the fluid is transferred from the tubular member to the pressure transmitting portion By flowing into the fluid-filled portion of the fluid-filled portion, the volume of the fluid-filled portion is expanded, and the elastic deformation is felt by hand, it is possible to obtain a feeling of practicing swallowing with the sense of the hand.

しかし、この種の訓練は単調であり、かつ、訓練の効果が表れるまで相当の期間を要するため、よほど強い意志がなければ、訓練を持続させることは難しい。特に、嚥下障害者が主として高齢者であることに鑑みると、適切な訓練方法とは言い難いところがある。そこで、日々の生活において必然的な飲料を飲むという行為と訓練を融合させるとのコンセプトに基づき、口腔内に挿入されて口腔内で外力を受けて弾性変形する軟質樹脂製の口腔内挿入部を飲料容器の口部に取り付けた嚥下訓練用の口腔リハビリ器具が提案されている(特許文献2)。かかる口腔リハビリ器具は、口腔内挿入部が被訓練者の口蓋窩へ収容されることで、高齢化に伴って舌が細くなったことにより生じた口蓋窩と舌の間の空間が埋まり、口腔内挿入部を介して口蓋窩に舌圧を加えることができて、その反作用で舌の根元に加わる力により喉頭蓋が倒れて気管が塞がれるようになるため、口腔内挿入部を吸引して口腔内挿入部の前端の孔から送出された飲料の嚥下を適正に行うことができるようになり、この訓練を継続することで、嚥下機能が回復していくというものである。   However, since this type of training is tedious and it takes a considerable amount of time until the effects of the training appear, it is difficult to sustain the training without a very strong will. In particular, considering that the person with dysphagia is mainly an elderly person, it is difficult to say that it is an appropriate training method. Therefore, based on the concept of combining the action of drinking an inevitable drink in daily life and training, an intraoral insertion part made of soft resin which is inserted in the oral cavity and elastically deformed in the oral cavity under external force An oral rehabilitation device for swallowing training attached to the mouth of a beverage container has been proposed (Patent Document 2). In such an oral rehabilitation device, when the intraoral insertion portion is accommodated in the palate fossa of the trainee, the space between the palate fossa and the tongue created due to the narrowing of the tongue as the population ages is buried, and the oral cavity Tongue pressure can be applied to the palatal fossa through the inner insertion part, and the epiglottis falls down by the force applied to the root of the tongue by the reaction, so that the trachea is blocked, so suctioning the intraoral insertion part It is possible to properly swallow the beverage delivered from the hole at the front end of the intraoral insertion portion, and by continuing this training, the swallowing function is restored.

本発明は、飲食という要素を取り入れて、使用持続可能性を向上させるとともに、さらに新たな機能を付加した口腔リハビリ器具を提供することを課題とする。   It is an object of the present invention to provide an oral rehabilitation device incorporating a food and drink component to improve the sustainability of use and to add a new function.

本発明に係る口腔リハビリ器具は、
中空で基端から先端にかけて内部に空間部を有するとともに、先端側であって口腔内奥行方向と交差する方向において空間部の内外を連通する孔を有し、口腔内に挿入される弾性変形可能な口腔内挿入部と、
内部の収容空間に流動食又は飲料が収容された柔軟性容器の口部に着脱自在に接続され、口腔内挿入部の空間部と柔軟性容器の収容空間とを連通する接続部とを備え
口腔内挿入部は、先端側の下面部に、下面部に接触した舌の先端部が入り込むよう誘導されるポケット部と、ポケット部よりも先端側に位置する隆起部とを備え、
空間部のうち、隆起部に対応する部分は、ポケット部に対応する部分よりも拡大される。
The oral rehabilitation device according to the present invention is
It is hollow and has a space inside from the base end to the tip, and has a hole that communicates the inside and the outside of the space in the direction that intersects the depth direction on the tip side, and can be elastically deformed inserted into the oral cavity Oral cavity insertion part,
A connecting portion which is detachably connected to the mouth of the flexible container containing fluid food or beverage in the inner storage space, and which communicates the space portion of the intraoral insertion portion and the storage space of the flexible container ;
The intraoral insertion portion includes a pocket portion which is guided so that the tip portion of the tongue in contact with the lower surface portion is inserted in the lower surface portion on the distal end side, and a raised portion which is positioned distal to the pocket portion.
Of the space, the portion corresponding to the raised portion is larger than the portion corresponding to the pocket.

かかる構成によれば、嚥下訓練を行う場合、使用者は、柔軟性容器を持って把握することで、柔軟性容器内の収容空間に収容されている内容物が柔軟性容器の口部から押し出され、接続部を介して口腔内挿入部内の空間部に供給される。そして、使用者は、舌を口腔内挿入部に当て、舌を押し上げて口腔内挿入部を口蓋に押し付ける。これにより、口腔内挿入部内の空間部に供給された内容物が孔から押し出され、口腔内に排出される。使用者は、嚥下動作をさらに進めることで、この内容物を飲み込むことができる。そして、訓練中は、舌に適切な負荷が掛かるため、使用者が訓練を継続することで、舌の筋力やその他嚥下に用いられる筋力が鍛錬され、嚥下機能の回復という効果が期待できる。   According to this configuration, when performing swallowing training, the user holds and grasps the flexible container, and the contents contained in the accommodation space in the flexible container are pushed out from the mouth of the flexible container. It is supplied to the space in the intraoral insertion part via the connection part. Then, the user puts the tongue on the intraoral insertion part, pushes up the tongue and presses the intraoral insertion part on the palate. Thereby, the contents supplied to the space in the intraoral insertion portion are pushed out of the hole and discharged into the oral cavity. The user can swallow this content by further advancing the swallowing operation. Since the tongue is appropriately loaded during training, the user can continue training to strengthen the tongue and other muscle forces used for swallowing, and it can be expected to have the effect of restoring swallowing function.

管体部50は、シリコーンゴム、熱可塑性エラストマー、PVC(ポリ塩化ビニル)といった軟質樹脂等の材料のチューブが用いられる。なお、管体部50は、通常は真っ直ぐであるが、本図においては、約90度湾曲させた状態で表している。管体部50の長さ、径及び硬さは、特に限定されないが、第二接続部55における管体部50の軸線に対する第一接続部51における管体部50の軸線の折れ曲がり角が少なくとも45度以上、より好ましくは、60度以上、さらに好ましくは、80度以上となることを可能とするものが選ばれる。   As the tube portion 50, a tube of a material such as silicone rubber, thermoplastic elastomer, soft resin such as PVC (polyvinyl chloride), etc. is used. Although the tube portion 50 is normally straight, it is shown in a state of being bent by about 90 degrees in this figure. The length, diameter and hardness of the tube portion 50 are not particularly limited, but the bending angle of the axis of the tube portion 50 at the first connection portion 51 with respect to the axis of the tube portion 50 at the second connection portion 55 is at least 45 What makes it possible to become more than 60 degrees, more preferably more than 60 degrees, more preferably more than 80 degrees is selected.

第一接続部51は、口腔内挿入具2の基部20が当接して基部20を受ける受け部52と、受け部52に着脱自在に取り付けられ、受け部52に口腔内挿入具2の基部20を固定するキャップ53とで構成される。   The first connection portion 51 is a receiver 52 that receives the base 20 while the base 20 of the intraoral insertion tool 2 abuts, and is detachably attached to the receiver 52, and the base 20 of the intraoral insertion tool 2 at the receiver 52 And a cap 53 for fixing the

受け部52は、口腔内挿入具2の基部20と同程度の大きさに形成される。本実施形態においては、口腔内挿入具2の基部20は、円環状であるため、受け部52の外形は、円形である。受け部52は、中心部に軸線方向に沿って孔52aを有する。また、孔52aの一部(孔52aの先端側の一部を除く部分)は、拡径され、ここに、管体部50の一端が挿入される。孔52aの拡径部の内径は、管体部50の外径よりも僅かに小さくなるよう設定されるため、拡径部に挿入した管体部50は簡単には抜けない。   The receiving part 52 is formed in the same size as the base 20 of the intraoral insertion tool 2. In the present embodiment, since the base 20 of the intraoral insertion tool 2 is annular, the outer shape of the receiving portion 52 is circular. The receiving portion 52 has a hole 52a at the center along the axial direction. Further, a part of the hole 52a (a part excluding a part on the tip side of the hole 52a) is expanded in diameter, and one end of the tube portion 50 is inserted here. The inner diameter of the enlarged diameter portion of the hole 52a is set to be slightly smaller than the outer diameter of the tube portion 50, so the tube portion 50 inserted into the enlarged diameter portion does not easily come off.

受け部52の外周には、雄ネジ部52bが形成される。他方、キャップ53の内周には、雌ネジ部53aが形成される。これにより、キャップ53は、受け部52に着脱自在に螺合される。なお、キャップ53を締める際に、受け部52が共回りしないよう、受け部52には、指を引っ掛けて受け部52の回転を規制する回転規制部52cが設けられる。本実施形態においては、回転規制部52cは、受け部52の基端側端面から軸方向に板状に突出する突起である。   An external thread 52 b is formed on the outer periphery of the receiving portion 52. On the other hand, on the inner periphery of the cap 53, a female screw portion 53a is formed. Thereby, the cap 53 is detachably screwed to the receiving portion 52. When the cap 53 is tightened, the receiving portion 52 is provided with a rotation restricting portion 52 c that hooks a finger to restrict rotation of the receiving portion 52 so that the receiving portion 52 does not rotate together. In the present embodiment, the rotation restricting portion 52 c is a protrusion that protrudes in a plate shape in the axial direction from the proximal end surface of the receiving portion 52.

キャップ53は、端部内周から内方向に環状に突出するフランジ部53cが形成されるようにして、中心部に孔53bを有する。フランジ部53cが口腔内挿入具2の基部20の括れ部22に嵌り、かつ簡単には抜けないよう、孔53bの内径は、口腔内挿入具2の基部20のフランジ部21の外径よりは小さく、かつ、括れ部22の外径と同じかそれよりも僅かに大きくなるよう設定される。   The cap 53 has a hole 53 b at the center thereof so as to form a flange portion 53 c which annularly protrudes inward from the inner periphery of the end portion. The inner diameter of the hole 53b is smaller than the outer diameter of the flange 21 of the base portion 20 of the intraoral insertion tool 2 so that the flange portion 53c fits into the constriction portion 22 of the base portion 20 of the intraoral insertion tool 2 and does not come off easily. It is set to be small and equal to or slightly larger than the outer diameter of the constricted portion 22.

第二接続部55は、中心部に軸線方向に沿って孔55aを有する。また、第二接続部55は、先端側端面から突出する筒状の差し込み部55bを有し、ここに、管体部50の他端が外嵌される。差し込み部55bの外径は、管状部50の内径よりも僅かに大きくなるよう設定されるため、差し込み部55bが挿入された管体部50は簡単には抜けない。   The second connection portion 55 has a hole 55a at the center along the axial direction. In addition, the second connection portion 55 has a cylindrical insertion portion 55b that protrudes from the end surface on the tip end side, and the other end of the tube portion 50 is externally fitted here. The outer diameter of the insertion portion 55b is set to be slightly larger than the inner diameter of the tubular portion 50, so the tube portion 50 into which the insertion portion 55b is inserted does not easily come off.

第二接続部55の内周には、柔軟性容器6の口部の外周に形成された雄ネジ部に対応する雌ネジ部55cが形成される。これにより、第二接続部55は、柔軟性容器6の口部に着脱自在に螺合される。   On the inner periphery of the second connection portion 55, a female screw portion 55c corresponding to the male screw portion formed on the outer periphery of the mouth of the flexible container 6 is formed. Thus, the second connection portion 55 is detachably screwed to the opening of the flexible container 6.

図5に示す如く、柔軟性容器6は、一般的には口栓(スパウト)付きのパウチ容器の形態が採られる。柔軟性容器6には、牛乳、卵、果汁、くず湯、重湯(おもゆ)、スープ、オートミール、飴砂糖類、ゼリー、プディング、ゼリータイプの健康食品、ゼリータイプの栄養補助食品といった流動食(流動性を有して咀嚼を要しない食物)が収容される。本実施形態においては、内容物が収容された市販のものが用いられる。   As shown in FIG. 5, the flexible container 6 generally takes the form of a pouch container with a spout. The flexible container 6 is a liquid food such as milk, egg, fruit juice, rubbish, heavy water (omuyu), soup, oatmeal, sugar cane, jelly, pudding, health food of jelly type, dietary supplement of jelly type Containing (food that is fluid and does not require chewing). In the present embodiment, a commercially available one containing the contents is used.

そして、接続部5の第一接続部51の受け部52の先端側端面に口腔内挿入具2の基部20のフランジ部21を当接させて、キャップ53を締め込むことにより、受け部52の先端側端面とキャップ53のフランジ部53cとで口腔内挿入具2の基部20のフランジ部21を挟み込んで、口腔内挿入具2(の基部20)と第一接続部51とが接続された状態にした上で、接続部5の第二接続部55を柔軟性容器6の口部60の雄ネジ部60aに螺合して、第二接続部55が柔軟性容器6の口部60に接続される。これにより、柔軟性容器6の口部60から接続部5を介して口腔内挿入具2は、内部の空間部が連通した状態となる。そのため、柔軟性容器6の口部60から排出された流動食は、接続部5の管体部50を通じて口腔内挿入具2内の空間部30に供給され、上面部26aの孔35からの注出が可能となる。   Then, the flange portion 21 of the base portion 20 of the intraoral insertion tool 2 is brought into contact with the distal end side end face of the receiving portion 52 of the first connection portion 51 of the connecting portion 5 to tighten the cap 53. State where the intraoral insertion tool 2 (the base 20 of the intraoral insertion tool 2 and the first connection portion 51 are connected) by sandwiching the flange portion 21 of the base 20 of the intraoral insertion tool 2 with the distal end side end face and the flange portion 53c of the cap 53 Then, the second connection portion 55 of the connection portion 5 is screwed into the male screw portion 60a of the opening 60 of the flexible container 6, and the second connection portion 55 is connected to the opening 60 of the flexible container 6 Be done. Thereby, the intraoral insertion tool 2 will be in the state which the internal space part connected via the connection part 5 from the opening part 60 of the flexible container 6. FIG. Therefore, the liquid food discharged from the opening 60 of the flexible container 6 is supplied to the space 30 in the intraoral insertion tool 2 through the tube 50 of the connection 5 and is poured from the hole 35 of the upper surface 26a. It will be possible to

本実施形態に係る訓練器具1は、以上の構成からなり、次に、この訓練器具1を用いた訓練方法について説明する。   Training equipment 1 concerning this embodiment consists of the above composition, and next, a training method using this training equipment 1 is explained.

図6に示す如く、被訓練者は、柔軟性容器6を持ち、柔軟性容器6を把握する。これにより、柔軟性容器6に外力が加わって柔軟性容器6内の収容空間が減容し、収容されている流動食が口部60から押し出され、接続部5内に排出される。そして、排出された流動食は、接続部5を介して口腔内挿入具2内の空間部30に供給される。しかし、孔35が口腔内挿入具2の頭部26の上面部26aに設けられ、孔35が口腔内奥行方向と交差する方向に形成されるため、被訓練者が口腔内挿入具2の頭部26を吸引しても、被訓練者の吸引力は、口腔内挿入具2内の空間部30に伝達されにくい。そのため、流動食は孔35から排出されにくくなっている。しかも、孔35が口腔内挿入具2の頭部26の上面部26aに設けられることで、口腔内挿入具2が口腔内に挿入された状態では、孔35は口蓋によって塞がれて閉塞状態ないし閉塞に近い状態となるため、流動食が孔35から排出されにくいのはなおさらである。   As shown in FIG. 6, the trainee holds the flexible container 6 and grasps the flexible container 6. As a result, an external force is applied to the flexible container 6 to reduce the volume of the storage space in the flexible container 6, and the contained liquid food is pushed out from the port 60 and discharged into the connection 5. Then, the discharged liquid food is supplied to the space 30 in the intraoral insertion tool 2 through the connection portion 5. However, since the hole 35 is provided in the upper surface portion 26a of the head 26 of the intraoral insertion tool 2 and the hole 35 is formed in a direction intersecting the intraoral depth direction, the trainee has the head of the intraoral insertion tool 2 Even when the portion 26 is suctioned, the suction force of the trainee is unlikely to be transmitted to the space portion 30 in the intraoral insertion tool 2. Therefore, it is difficult for the liquid food to be discharged from the holes 35. Moreover, by providing the hole 35 in the upper surface portion 26a of the head 26 of the intraoral insertion tool 2, when the intraoral insertion tool 2 is inserted into the oral cavity, the hole 35 is blocked by the palate and a closed state Further, it is even more difficult for the liquid food to be discharged from the holes 35 because the state is close to a blockage.

したがって、被訓練者が流動食を摂食するには、被訓練者は、口腔内挿入具2内の空間部30に貯留されている流動食を押し出して孔35から排出させる動作が必要となる。この動作を具体的に表したのが図7である。被訓練者は、まず、図7(a)に示す如く、舌の先端部を口腔内挿入具2の頭部26の下面部26bに接触させる。すると、頭部26の下面部26bには、ポケット部27が形成されているため、舌の先端部はポケット部27に誘導される。これにより、被訓練者の舌は、口腔内挿入具2の頭部26の位置を円滑かつ確実に捉えることができる。   Therefore, in order for the trainee to eat the liquid food, the trainee needs an operation to push out the liquid food stored in the space 30 in the intraoral insertion tool 2 and discharge it from the hole 35. . FIG. 7 specifically shows this operation. The trainee first brings the tip of the tongue into contact with the lower surface 26b of the head 26 of the intraoral insertion tool 2, as shown in FIG. 7 (a). Then, since the pocket portion 27 is formed on the lower surface portion 26 b of the head portion 26, the tip of the tongue is guided to the pocket portion 27. Thereby, the tongue of the trainee can catch the position of the head 26 of the intraoral insertion tool 2 smoothly and reliably.

被訓練者は、次に、同図(b)に示す如く、舌の先端部を口蓋に向けて押し上げて、口腔内挿入具2の頭部26を口蓋に当たるようにする。これにより、口腔内挿入具2の頭部26は口蓋に支持されるため、舌の先端部による力は、口腔内挿入具2の頭部26に確実に伝達され、口腔内挿入具2の頭部26を弾性変形させる力に転換可能となる。   Next, the trainee pushes up the tip of the tongue toward the palate to make the head 26 of the intraoral insertion tool 2 hit the palate as shown in FIG. Thereby, since the head 26 of the intraoral insertion tool 2 is supported by the palate, the force by the tip of the tongue is reliably transmitted to the head 26 of the intraoral insertion tool 2 and the head of the intraoral insertion tool 2 It becomes possible to convert the force to elastically deform the portion 26.

そこで、被訓練者は、同図(c)に示す如く、嚥下動作と同様、舌全体を口蓋に向けて押し上げる。すると、舌は、ポケット部27の先にある隆起部28を弾性変形させて押し潰す。これにより、隆起部28内にある頭部内第二空間部34が減容し、頭部内第二空間部34に貯留されている流動食が孔35から押し出され、口腔内に排出される。被訓練者は、嚥下動作をさらに進めることで、この流動食を飲み込むことができる。なお、隆起部28は、後壁部28bを中心側が凹む凹面状にして、潰しやすくしている。   Therefore, the trainee pushes up the entire tongue toward the palate as shown in FIG. Then, the tongue elastically deforms and crushes the ridge 28 at the end of the pocket 27. As a result, the volume of the second space 34 in the head in the raised portion 28 is reduced, and the fluid food stored in the second space 34 in the head is pushed out of the hole 35 and discharged into the oral cavity . The trainee can swallow this liquid food by further advancing the swallowing operation. In addition, the raised portion 28 is formed in a concave shape in which the rear wall portion 28 b is concaved at the center side so as to be easily crushed.

このように、本実施形態に係る訓練器具1を用いた訓練方法によれば、舌に適切な負荷が掛かるため、被訓練者が訓練を継続することで、舌の筋力やその他嚥下に用いられる筋力が鍛錬され、嚥下機能の回復という効果が期待される。しかも、本実施形態に係る訓練器具1を用いた訓練方法は、日々の生活において必然的な摂食行動を融合させた(組み合わせた)ものであるため、単に鍛錬を行うという単純目的の訓練方法に比べて、使用(訓練)持続可能性が高い。したがって、本実施形態に係る訓練器具1を用いた訓練方法によれば、より多くの被訓練者において、嚥下機能の回復という効果が見込まれる。   As described above, according to the training method using the training instrument 1 according to the present embodiment, since the tongue is appropriately loaded, it is used for muscle power and other swallowing of the tongue by the trainee continuing training. Strength is trained, and the effect of recovery of swallowing function is expected. Moreover, since the training method using the training instrument 1 according to the present embodiment is a combination (combination) of inevitable eating behavior in daily life, the training method for the simple purpose of simply performing training Compared to, use (training) is more sustainable. Therefore, according to the training method using the training instrument 1 according to the present embodiment, the effect of restoration of the swallowing function can be expected in more trainees.

また、本実施形態に係る訓練器具1を用いた訓練方法によれば、舌の先端部の動きが口腔内挿入具2の頭部内空間部(頭部内第一空間部33及び頭部内第二空間部34)を基端側から先端側に絞り上げていくという動作が的確に行われたならば、多くの量の流動食が頭部内空間部に留まることなく孔35から絞り出されるため、被訓練者は、訓練を適切に行えているか否かを口腔内挿入具2から排出される流動食の量で確認することができる。   In addition, according to the training method using the training instrument 1 according to the present embodiment, the movement of the tip portion of the tongue is the space in the head of the intraoral insertion tool 2 (the first space 33 in the head and the head If the operation of squeezing the second space 34) from the proximal end to the distal end is properly performed, a large amount of fluid corrosion is squeezed out of the hole 35 without remaining in the head space. Therefore, the trainee can confirm whether the training is properly performed by the amount of liquid food discharged from the intraoral insertion tool 2.

また、上述のとおり、被訓練者が口腔内挿入具2の頭部26を吸引しても、流動食は孔35から排出されにくく、流動食を得るためには、適切な嚥下動作を行わなければならない。したがって、本実施形態に係る訓練器具1を用いた訓練方法によれば、被訓練者の意識の有無に関わらず、自然的に正しい訓練をするように仕向けられるため、効果の上がらない意図しない訓練が行われてしまうのを好適に防止することができる。   Also, as described above, even if the trainee aspirates the head 26 of the intraoral insertion tool 2, it is difficult for fluid food to be discharged from the holes 35, and in order to obtain fluid food, appropriate swallowing operation must be performed. You must. Therefore, according to the training method using the training instrument 1 according to the present embodiment, regardless of the presence or absence of the trainee's awareness, he / she is naturally instructed to perform the correct training, so unintended training which is not effective. Can be suitably prevented.

また、本実施形態に係る訓練器具1は、口腔内挿入具2と柔軟性容器6との間に可撓性を有して湾曲可能な接続具5を介在させ、柔軟性容器6に対する口腔内挿入具2の方向を変更可能にしている。そのため、柔軟性容器6を立てた状態で持って(口部60が上になるように持って)、そのままの姿勢で訓練を行うことができる。仮に柔軟性容器6を斜めに持ち上げて訓練を行う場合、顎が浮き、頭が上向きになった姿勢になりやすいが、そうなると、適切な嚥下動作を行うことができず、誤嚥しやすくなる。しかし、本実施形態に係る訓練器具1を用いた訓練方法によれば、頭は視線が水平方向を向く通常姿勢を維持することができるため、オトガイ部を引いた適切な嚥下姿勢の下、適切な嚥下動作を行うことができ、誤嚥の発生を防ぐことができる。   In addition, the training instrument 1 according to the present embodiment has a flexible bendable connector 5 between the intraoral insertion tool 2 and the flexible container 6, and the intraoral cavity for the flexible container 6. The direction of the insertion tool 2 can be changed. Therefore, the flexible container 6 can be held upright (with the mouth 60 facing up) and training can be performed in the same posture. If training is performed by lifting the flexible container 6 at an angle, the jaws are lifted and the head is likely to be in an upward position, but if this happens, the proper swallowing operation can not be performed, and errors easily occur. However, according to the training method using the training instrument 1 according to the present embodiment, the head can maintain the normal posture in which the sight line is in the horizontal direction. It is possible to perform a proper swallowing operation and to prevent the occurrence of an error.

加えて、本実施形態に係る訓練器具1を用いた訓練方法は、必要かつ十分な量の流動食を口腔内挿入具2内の空間部30に供給するために、柔軟性容器6の把握運動を行う必要がある。また、訓練中は、流動食が口腔内挿入具2から適宜排出されていくので、減った分を口腔内挿入具2内の空間部30に補充するためにも、柔軟性容器6の把握運動を行う必要がある。したがって、訓練中における柔軟性容器6の把握運動は、それなりの運動量となる。手は「第2の脳」とも呼ばれ、指先を動かせば、脳に刺激が伝わり、脳を活性化させることができる。したがって、本実施形態に係る訓練器具1を用いた訓練方法によれば、認知症予防や脳機能障害のリハビリ、さらには、手や手指の筋力向上という、嚥下機能回復とは全く異質の効果も同時的に期待することができる。本実施形態に係る訓練器具1を「手の把握運動促進機能付きの嚥下訓練器具」と称する所以である。   In addition, the training method using the training instrument 1 according to the present embodiment is a grasping movement of the flexible container 6 in order to supply a necessary and sufficient amount of fluid food to the space portion 30 in the intraoral insertion tool 2 Need to do. In addition, since the liquid food is appropriately discharged from the intraoral insertion tool 2 during training, the grasping movement of the flexible container 6 is also for replenishing the reduced portion to the space portion 30 in the intraoral insertion tool 2 Need to do. Therefore, the grasping movement of the flexible container 6 during training has a proper amount of movement. The hand is also called the "second brain", and if you move your fingertips, the stimulation can be transmitted to the brain and the brain can be activated. Therefore, according to the training method using the training instrument 1 according to the present embodiment, the effect of completely different in swallowing function recovery, such as dementia prevention and rehabilitation of brain dysfunction, muscle strength improvement of hands and fingers is also different. You can expect at the same time. The training instrument 1 according to the present embodiment is hereinafter referred to as "a swallow training instrument with a hand grasping exercise promoting function".

また、本実施形態に係る訓練器具1を用いた訓練方法によれば、食事の自主性(他人からスプーンで口に放り込まれるのではなく、飲む量とタイミングを自分で決められる)を保ち、当該者の人格の尊厳を守ることができるという利点もある。   In addition, according to the training method using the training instrument 1 according to the present embodiment, the independence of the meal (the amount and timing of drinking can be decided by oneself rather than being thrown into the mouth with a spoon from others) is maintained, Has the advantage of being able to protect the dignity of the person's personality.

口腔前庭介装部36は、口腔内挿入具2の本体部24に設けられ、本体部24と一体成形される。口腔前庭介装部36は、周縁部36aが肉厚になっており、それ以外(周縁部36aよりも内側)が薄肉となっている。このため、口腔前庭介装部36の保形性が肉厚の周縁部36aによって得られつつも、薄肉部によって変形性(柔軟性)が得られ、図9(d)に示す如く、口腔内挿入具2の本体部24が上面側と下面側とで異なる変形をしても、上部介装部36a及び下部介装部36bは、それぞれ上下の口腔前庭に好適に介装される。また、口腔内庭介装部36は、同図(c)に示す如く、後傾している。これは、前歯の傾斜に合わせてフィット感を高めるためである。   The oral vestibular prosthesis portion 36 is provided on the main body portion 24 of the intraoral insertion tool 2 and is integrally molded with the main body portion 24. In the oral vestibular prosthesis portion 36, the peripheral portion 36a is thick, and the other portion (inner side than the peripheral portion 36a) is thin. Therefore, while the shape retaining property of the oral vestibular prosthesis portion 36 is obtained by the thick peripheral portion 36a, deformability (flexibility) is obtained by the thin portion, and as shown in FIG. Even if the main body portion 24 of the insertion tool 2 is deformed differently on the upper surface side and the lower surface side, the upper insertion portion 36a and the lower insertion portion 36b are preferably interposed in the upper and lower oral vestibule, respectively. Also, the intraoral gardener section 36 is inclined backward as shown in FIG. This is to improve the fit according to the inclination of the front teeth.

また、口腔前庭介装部は、図10に示す如く、口腔前庭介装具7として、口腔内挿入具2とは別体に構成することもできる。同図に示す例では、口腔前庭介装具7は、口腔内挿入具2と同じ材質で形成されて、弾性変形可能であり、口腔内挿入具2と同様、フランジ部70を有し、かつ、口腔内挿入具2の基端側を内挿する胴部71を有する。そして、口腔前庭介装具7のフランジ部70に口腔内挿入具2のフランジ部21を重ねて一体化した状態で、図5に示す如く、キャップ53を締めて取り付ける。両者を別体に構成することで、いずれか一方のみを交換することができ、また、一体に構成するよりも低コストで製造することが可能となる。   Further, as shown in FIG. 10, the oral vestibular prosthesis part can be configured separately from the intraoral insertion tool 2 as the oral vestibular prosthesis 7. In the example shown in the figure, the oral vestibular prosthesis 7 is formed of the same material as the intraoral insertion tool 2 and is elastically deformable, and has a flange portion 70 as in the intraoral insertion tool 2, It has the trunk | drum 71 which inserts the base end side of the intraoral insertion tool 2. As shown in FIG. Then, in a state where the flange portion 21 of the intraoral insertion tool 2 is overlapped and integrated with the flange portion 70 of the oral vestibular prosthesis 7, as shown in FIG. 5, the cap 53 is tightened and attached. By separately configuring the two, only one of them can be replaced, and manufacturing can be performed at lower cost than when they are integrally configured.

また、本発明に係る口腔リハビリ器具は、図11に示す如く、ポケット部27の後方、すなわち、隆起部28の頂部あるいはその近傍に、口腔内挿入具2の頭部26の幅方向、すなわち、口腔内奥行方向と交差する方向に沿って延びる凸条37を備えることができる。生体では、硬口蓋のヒダ(口蓋ヒダ)が洗濯板のように舌をきれいにしたり、食物を送りやすくする働きがあるが、これと同様にして、凸条37を設けることにより、舌背をきれいにしたり、舌を適度に刺激する、あるいは舌の先端部をポケット部27に入れる際の感覚の目安になるという効果が期待できる。凸条37は、一本でもよいし、並列して複数本設けるようにしてもよい。   Further, as shown in FIG. 11, the oral cavity rehabilitation device according to the present invention is, as shown in FIG. 11, behind the pocket 27, that is, in the width direction of the head 26 of the intraoral insertion device 2, that is, A ridge 37 may be provided extending along a direction intersecting the intraoral depth direction. In the living body, the hard palate folds (palatal folds) have the function of cleaning the tongue and facilitating the feeding of food like a washing plate, but in the same manner, providing the ridges 37 enables the tongue back The effect of cleaning the skin, stimulating the tongue moderately, or being a measure of feeling when the tip of the tongue is put into the pocket 27 can be expected. One convex line 37 may be provided, or a plurality of convex lines 37 may be provided in parallel.

また、上記実施形態においては、流動食を摂食するものである。しかし、流動食でなく、水、茶、ジュースといった飲料であってもよい。この場合、飲料は流動食よりも孔からの排出性がよいことから、孔の大きさは流動食用のものよりは小さく設定される。あるいは、無負荷時は孔が閉塞される上記スリットタイプの孔であれば、一つで流動食用と飲料用の両方を兼用することができる。   Moreover, in the said embodiment, it eats a liquid food. However, instead of liquid food, it may be a beverage such as water, tea or juice. In this case, the size of the hole is set smaller than that of the fluid food since the beverage has better drainability from the hole than the liquid food. Alternatively, in the case of the slit type hole in which the hole is closed at the time of no load, it is possible to use both for fluid food and for beverage by one.

また、上記実施形態においては、柔軟性容器6は内容物が収容された市販のものが用いられ、そのため、口栓(スパウト)の口部60は、一般的な形状である。しかし、本発明に係る口腔リハビリ器具の接続部と柔軟性容器の口部の接続形状を独自の形状とした専用の柔軟性容器を設け、その柔軟性容器しか接続できないようにしてもよい。その場合、高齢者向けに開発された栄養補助剤等の内容物が充填されたものを専用の市販品とし、これを購入して接続するとか、使用者や介助者が柔軟性容器に水、茶等の内容物を入れて接続するという使い方を含め、いろいろな使い方ができる。   Moreover, in the said embodiment, the commercially available thing in which the content was accommodated is used for the flexible container 6, Therefore, the opening part 60 of a spout (spout) is a general shape. However, a dedicated flexible container may be provided in which the connection shape of the connection part of the oral cavity rehabilitation device according to the present invention and the opening of the flexible container is unique, so that only the flexible container can be connected. In that case, what is filled with contents such as a nutritional supplement developed for elderly people is taken as a dedicated commercial product, purchased and connected, or the user or assistant uses water in a flexible container, It can be used in various ways, including the use of putting contents such as tea and connecting them.

また、本発明は、口腔内挿入具と柔軟性容器との組み合わせに係るものである。しかし、上記口腔内挿入具(及び口腔前庭介装具)は、それだけでも特徴的なものであるため、柔軟性容器との組み合わせに限定されない発明として成立し得る。   The present invention also relates to the combination of an intraoral insert and a flexible container. However, the above-mentioned intraoral insertion tool (and the oral vestibular prosthesis) can be realized as an invention that is not limited to the combination with the flexible container, since it is a feature alone.
