Description

本発明は、全体が弾性変形可能であると共に口腔に挿入される口腔挿入具に関する。 The present invention relates to an oral inserter that is elastically deformable as a whole and is inserted into the oral cavity.

従来、口唇の粘膜と前歯の歯肉の粘膜との間に嵌め込んで、口唇閉鎖力の強化又は顔面筋のストレッチ等を行う器具が知られている。かかる器具は、口腔の外部から負荷を加えるのではなく、口腔の内部から外部に向けて口輪筋に負荷を加えるものである。 Conventionally, there are known devices that are fitted between the mucous membrane of the lips and the gingival mucosa of the anterior teeth to strengthen the lip closing force or stretch the facial muscles. Such an instrument does not apply a load from the outside of the oral cavity, but applies a load to the orbicularis oris muscle from the inside to the outside of the oral cavity.

特許文献１は、口腔に挿入して顔面筋のストレッチを行う口腔挿入具を開示している。特許文献１の口腔挿入具は、内部に開口部を設けた略楕円形の口内掛止部と、口内掛止部と平行に設けられる表面引張部と、表面引張部に設けられる引張紐と、を有している。かかる口腔挿入具は、口内掛止部を口の中に噛合し、口をつぐむと共に引張紐を手に持って引張操作することによって、口内掛止部が口の内側から直接に表情筋を引張るので、表情筋に負荷が掛かって皮膚面のトレーニング効果を得ることができる。 Patent Document 1 discloses an oral insertion tool that is inserted into the oral cavity to stretch facial muscles. The oral insertion tool of Patent Document 1 includes a substantially elliptical mouth hook portion having an opening inside, a surface tension portion provided parallel to the mouth hook portion, and a tension string provided on the surface tension portion. have. In such an oral insertion tool, the mouth hook is engaged in the mouth, the mouth is pinched, and the tension string is held in the hand for pulling operation, so that the mouth hook pulls the facial muscles directly from the inside of the mouth. Therefore, a load is applied to the facial muscles, and a training effect on the skin surface can be obtained.

しかしながら、特許文献１においては、口輪筋のトレーニング効果を得ることはできるものの、実際の口腔は複雑且つ微妙に湾曲しているため、口輪筋以外の表情筋にトレーニング効果を得ることができる程度の負荷を掛けることは困難であるという課題を有する。 However, in Patent Document 1, although the training effect of the orbicularis oris muscle can be obtained, the training effect can be obtained on the facial muscles other than the orbicularis oris muscle because the actual oral cavity is complicated and slightly curved. It has a problem that it is difficult to apply a certain amount of load.

本発明の目的は、口輪筋に加えて、口輪筋以外の他の表情筋にも負荷を掛けることができ、顔面のトレーニング効果を向上させることができる口腔挿入具を提供することである。 An object of the present invention is to provide an oral insertion tool capable of applying a load to other facial muscles other than the orbicularis oris muscle in addition to the orbicularis oris muscle and improving the facial training effect. ..

本発明に係る口腔挿入具は、全体が弾性変形可能であると共に口腔に挿入される口腔挿入具であって、前方に凸形状となるように湾曲する板状の湾曲部と、前記湾曲部より前方に突出する突出部と、前記湾曲部の上端より前方且つ内方に向けて湾曲して延設されると共に、先端が前記突出部の前端よりも後方に位置する舌状の上側負荷付与部と、前記湾曲部の下端より前記上側負荷付与部に近づくように前方且つ内方に向けて湾曲して延設されると共に、先端が前記突出部の前端よりも後方に位置する舌状の下側負荷付与部と、を有する。 The oral cavity inserter according to the present invention is an oral cavity inserter that is elastically deformable as a whole and is inserted into the oral cavity, from a plate-shaped curved portion that curves forward so as to have a convex shape, and the curved portion. A protruding portion that protrudes forward and a tongue-shaped upper load applying portion that is curved and extended inward and forward from the upper end of the curved portion and whose tip is located behind the front end of the protruding portion. The tongue-shaped lower portion is curved forward and inward so as to approach the upper load applying portion from the lower end of the curved portion, and the tip is located behind the front end of the protruding portion. It has a side load applying portion.

口腔挿入具を口腔に装着した際に、口輪筋及び口輪筋と他の表情筋との吻合部の付近に位置する上側負荷付与部により上口唇付近が前方に押圧されると共に、口輪筋及び口輪筋と他の表情筋との吻合部の付近に位置する下側負荷付与部により下口唇付近が前方に押圧された際に、この押圧力に抗して口を閉じる動作を行うことにより、口輪筋に対して負荷を掛けることができると共に、口輪筋と他の表情筋との吻合部に対しても、口輪筋以外の他の表情筋のトレーニング効果を得ることができる程度の負荷を掛けることができる。 When the orbicularis oris insert is attached to the oral cavity, the area around the upper lip is pressed forward by the orbicularis oris muscle and the upper load applying portion located near the anastomosis between the orbicularis oris muscle and other facial muscles, and the muzzle. When the lower lip is pressed forward by the lower load applying portion located near the anastomotic portion between the muscles and the orbicularis oris muscle and the other facial muscles, the mouth is closed against this pressing force. As a result, it is possible to apply a load to the orbicularis oris muscle, and it is also possible to obtain a training effect of other facial muscles other than the orbicularis oris muscle on the anastomotic portion between the orbicularis oris muscle and other facial muscles. It is possible to apply as much load as possible.

本発明によれば、口輪筋に加えて、口輪筋以外の他の表情筋にも負荷を掛けることができ、顔面のトレーニング効果を向上させることができる。 According to the present invention, in addition to the orbicularis oris muscle, a load can be applied to facial muscles other than the orbicularis oris muscle, and the facial training effect can be improved.

＜口腔挿入具の使用方法＞
本発明の実施形態に係る口腔挿入具１の使用方法につき、図７を参照しながら、以下に詳細に説明する。 <How to use the oral insert>
The method of using the oral insertion tool 1 according to the embodiment of the present invention will be described in detail below with reference to FIG. 7.

まず、湾曲部１０の後面を口唇に対向させた状態から、湾曲部１０の後面が前歯の歯牙及び歯肉に当接するまで、湾曲部１０を弾性変形させながら口腔挿入具１を口腔に挿入する。この際に、窪み部１０７及び窪み部３４を上唇小帯に係合させると共に、窪み部１０８及び窪み部４４を下唇小帯に係合させる。 First, the oral insertion tool 1 is inserted into the oral cavity while elastically deforming the curved portion 10 from the state where the rear surface of the curved portion 10 faces the lip until the rear surface of the curved portion 10 abuts on the teeth and gingiva of the anterior teeth. At this time, the recessed portion 107 and the recessed portion 34 are engaged with the upper lip zonule, and the recessed portion 108 and the recessed portion 44 are engaged with the lower lip zonule.

湾曲部１０の後面が歯牙及び歯肉に当接した際に口腔に対する口腔挿入具１の挿入を止めて、上口唇を上側載置部２０６に載置させると共に下口唇を下側載置部２０７に載置させることにより、口腔に対する口腔挿入具１の装着を完了する。 When the rear surface of the curved portion 10 comes into contact with the teeth and gingiva, the insertion of the oral insertion tool 1 into the oral cavity is stopped, the upper lip is placed on the upper mounting portion 206, and the lower lip is placed on the lower mounting portion 207. By placing it on the oral cavity, the attachment of the oral cavity inserter 1 to the oral cavity is completed.

この際、上口唇は上側口唇当接部２０３と上側負荷付与部３０とに挟まれると共に、下口唇は下側口唇当接部２０４と下側負荷付与部４０とに挟まれ、更に、上側負荷付与部３０及び下側負荷付与部４０が片持ち形状で弾性変形して上口唇及び下口唇を前方に付勢するため、口腔挿入具１を安定した状態で口腔に装着することができる。 At this time, the upper lip is sandwiched between the upper lip contact portion 203 and the upper load applying portion 30, and the lower lip is sandwiched between the lower lip contact portion 204 and the lower load applying portion 40. Since the applying portion 30 and the lower load applying portion 40 are elastically deformed in a cantilever shape to urge the upper lip and the lower lip forward, the oral insertion tool 1 can be attached to the oral cavity in a stable state.

また、上側負荷付与部３０に窓孔３２及び窓孔３３を設けると共に、下側負荷付与部４０に窓孔４２及び窓孔４３を設けることにより、上側負荷付与部３０及び下側負荷付与部４０が弾性変形する際に上側負荷付与部３０及び下側負荷付与部４０の肉を窓孔４２及び窓孔４３に逃がすことができ、上側負荷付与部３０及び下側負荷付与部４０を口唇及び歯肉の粘膜に柔らかく接触させることができる。特に、上側負荷付与部３０の窪み部３４に対して左右方向の一方側の略中央に窓孔３２を設けると共に、上側負荷付与部３０の窪み部３４に対して左右方向の他方側の略中央に窓孔３３を設けることにより、窓孔３２の周囲の肉又は窓孔３３の周囲の肉を窓孔３２又は窓孔３３に均等に逃がすことができ、上側負荷付与部３０の全体を口唇及び歯肉の粘膜に柔らかく接触させることができる。同様に、下側負荷付与部４０の窪み部４４に対して左右方向の一方側の略中央に窓孔４２を設けると共に、下側負荷付与部４０の窪み部４４に対して左右方向の他方側の略中央に窓孔４３を設けることにより、窓孔４２の周囲の肉又は窓孔４３の周囲の肉を窓孔４２又は窓孔４３に均等に逃がすことができ、下側負荷付与部４０の全体を口唇及び歯肉の粘膜に柔らかく接触させることができる。 Further, by providing the window hole 32 and the window hole 33 in the upper load applying portion 30 and providing the window hole 42 and the window hole 43 in the lower load applying portion 40, the upper load applying portion 30 and the lower load applying portion 40 are provided. The meat of the upper load applying portion 30 and the lower load applying portion 40 can be released to the window hole 42 and the window hole 43 when the upper load applying portion 30 and the lower load applying portion 40 are elastically deformed. Can be softly contacted with the mucous membrane of the window. In particular, a window hole 32 is provided in the substantially center of one side in the left-right direction with respect to the recessed portion 34 of the upper load applying portion 30, and the window hole 32 is provided substantially in the center of the other side in the left-right direction with respect to the recessed portion 34 of the upper load applying portion 30. By providing the window hole 33 in the window hole 33, the meat around the window hole 32 or the meat around the window hole 33 can be evenly released to the window hole 32 or the window hole 33, and the entire upper load applying portion 30 can be lips and the entire upper load applying portion 30. Can be brought into soft contact with the gingival mucosa. Similarly, a window hole 42 is provided at substantially the center of one side in the left-right direction with respect to the recess 44 of the lower load applying portion 40, and the other side in the left-right direction with respect to the recess 44 of the lower load applying portion 40. By providing the window hole 43 substantially in the center of the above, the meat around the window hole 42 or the meat around the window hole 43 can be evenly released to the window hole 42 or the window hole 43, and the lower load applying portion 40 can be provided. The whole can be softly contacted with the mucous membranes of the lips and gums.

口腔挿入具１を口腔に装着した状態において、引張部５０は口腔から外部に突出している。また、口腔挿入具１を口腔に装着した状態において、貫通孔１０５及び貫通孔１０６を介して呼吸することができる。 When the oral insertion tool 1 is attached to the oral cavity, the tension portion 50 projects outward from the oral cavity. Further, with the oral insertion tool 1 attached to the oral cavity, it is possible to breathe through the through hole 105 and the through hole 106.

口腔挿入具１を口腔に装着した状態において、引張部５０を前方に引っ張ることにより、上口唇が上側負荷付与部３０を後方に弾性変形させると共に、下口唇が下側負荷付与部４０を後方に弾性変形させる。この際、上側負荷付与部３０の弾性復帰力により上口唇が前方に押圧されると共に、下側負荷付与部４０の弾性復帰力により下口唇が前方に押圧され、これらの押圧力に打ち勝つように口を閉じることにより、表情筋に負荷を加えることができる。 With the oral insertion tool 1 attached to the oral cavity, by pulling the tension portion 50 forward, the upper lip elastically deforms the upper load applying portion 30 backward, and the lower lip elastically deforms the lower load applying portion 40 backward. Elastically deform. At this time, the upper lip is pressed forward by the elastic returning force of the upper load applying portion 30, and the lower lip is pressed forward by the elastic returning force of the lower load applying portion 40 so as to overcome these pressing forces. By closing the mouth, the facial muscles can be stressed.

ここで、図７に示すように、表情筋の一つである口輪筋ｋ１の縁部には、口輪筋ｋ１の筋組織と他の多くの表情筋の筋組織とが混ざり合うように吻合して繋がっているため、直線に近い部分もある一方、小帯の存在により大きく湾曲している部分、及び頬小帯付近等において鋭角を形成して繋がっている部分もある。従って、口輪筋ｋ１と他の表情筋との吻合部ｆ１、ｆ２及びｆ３の吻合状態は一様ではない。本実施形態における口腔挿入具１は、口輪筋ｋ１と他の表情筋との吻合部ｆ１、ｆ２及びｆ３の付近に位置する上側負荷付与部３０の上側片１０１側の部分及び下側負荷付与部４０の下側片１０２側の部分が、各吻合部ｆ１、ｆ２及びｆ３に負荷を掛けることとなり、吻合状態が一様ではない各吻合部ｆ１、ｆ２及びｆ３を確実にストレッチすることができる。これにより、口輪筋ｋ１以外の他の表情筋に対しても、各吻合部ｆ１、ｆ２及びｆ３を介してトレーニング効果を得ることができる程度の負荷を掛けることができる。 Here, as shown in FIG. 7, the muscle tissue of the orbicularis oris muscle k1 and the muscle tissue of many other facial muscles are mixed at the edge of the orbicularis oris muscle k1 which is one of the facial muscles. Since they are anastomosed and connected, some parts are close to a straight line, while others are largely curved due to the presence of zonules, and some parts are connected by forming a sharp angle near the buccal zonules. Therefore, the anastomotic states of the anastomotic portions f1, f2, and f3 between the orbicularis oris muscle k1 and other facial muscles are not uniform. The oral insertion tool 1 in the present embodiment includes the upper piece 101 side portion and the lower load applying portion of the upper load applying portion 30 located near the anastomotic portions f1, f2 and f3 between the muzzle muscle k1 and other facial muscles. The portion on the lower piece 102 side of the portion 40 puts a load on the anastomotic portions f1, f2 and f3, and the anastomotic portions f1, f2 and f3 whose anastomotic states are not uniform can be reliably stretched. .. As a result, it is possible to apply a load to other facial muscles other than the orbicularis oris muscle k1 to the extent that a training effect can be obtained through the anastomotic portions f1, f2 and f3.

また、押圧部３５及び押圧部４５により、口腔の圧点を内部から押圧することができるため、トレーニング効果をより向上させることができる。 Further, since the pressure point of the oral cavity can be pressed from the inside by the pressing portion 35 and the pressing portion 45, the training effect can be further improved.

また、上側口唇当接部２０３及び下側口唇当接部２０４を設けることにより、口腔に装着された口腔挿入具１が必要以上に後方に移動しようとした際に、上口唇が上側口唇当接部２０３を前方に押圧すると共に下口唇が下側口唇当接部２０４を前方に押圧して、口腔挿入具１の後方への移動を阻止するため、口腔挿入具１により歯肉の粘膜を必要以上に押圧することがなく、痛みをなくすることができる。 Further, by providing the upper lip contact portion 203 and the lower lip contact portion 204, the upper lip comes into contact with the upper lip when the oral cavity inserter 1 attached to the oral cavity tries to move backward more than necessary. In order to prevent the oral insert 1 from moving backward by pressing the portion 203 forward and the lower lip pressing the lower lip contact portion 204 forward, the oral insert 1 makes the gingival mucosa more than necessary. You can eliminate the pain without pressing on the lips.

また、上側負荷付与部３０の後面に網目状の凸部３１を設けると共に、下側負荷付与部４０の後面に網目状の凸部４１を設けることにより、上側負荷付与部３０及び下側負荷付与部４０の弾性力を向上させることができるため、口輪筋ｋ１と他の表情筋との吻合部ｆ１、ｆ２及びｆ３に対してより強い負荷を掛けることができると共に、上側負荷付与部３０及び下側負荷付与部４０の意図しない変形を防ぐことができる。 Further, by providing the mesh-like convex portion 31 on the rear surface of the upper load applying portion 30 and providing the mesh-like convex portion 41 on the rear surface of the lower load applying portion 40, the upper load applying portion 30 and the lower load applying portion 30 are provided. Since the elastic force of the portion 40 can be improved, a stronger load can be applied to the anastomotic portions f1, f2 and f3 of the orbicularis oris muscle k1 and other facial muscles, and the upper load applying portion 30 and the upper load applying portion 30 and It is possible to prevent unintended deformation of the lower load applying portion 40.

また、突出部２０に凹部２０５を設けることにより、突出部２０の弾性力を向上させることができるため、口輪筋ｋ１と他の表情筋との吻合部ｆ１、ｆ２及びｆ３に対してより強い負荷を掛けることができる。 Further, by providing the recess 205 in the protrusion 20, the elastic force of the protrusion 20 can be improved, so that the protrusion 20 is stronger than the anastomotic portions f1, f2 and f3 between the orbicularis oris muscle k1 and other facial muscles. You can apply a load.

更に、上側負荷付与部３０に窓孔３２及び窓孔３３を設けると共に、下側負荷付与部４０に窓孔４２及び窓孔４３を設けることにより、上側負荷付与部３０及び下側負荷付与部４０における口唇及び歯肉の粘膜との接触面積を小さくすることができ、上側負荷付与部３０及び下側負荷付与部４０が口唇及び歯肉の粘膜に貼り付いてしまうことを防ぐことができる。 Further, by providing the window hole 32 and the window hole 33 in the upper load applying portion 30 and providing the window hole 42 and the window hole 43 in the lower load applying portion 40, the upper load applying portion 30 and the lower load applying portion 40 are provided. The contact area between the lip and the gingival mucosa can be reduced, and the upper load applying portion 30 and the lower load applying portion 40 can be prevented from sticking to the lip and gingival mucosa.

なお、口腔挿入具１により負荷を掛けることが可能な図７に示す吻合部ｆ１、ｆ２及びｆ３は例示であって、口輪筋ｋ１と口輪筋ｋ１以外の表情筋との吻合部ｆ１、ｆ２及びｆ３以外の吻合部に対しても口腔挿入具１により負荷を掛けることができる。 The anastomotic portions f1, f2 and f3 shown in FIG. 7, which can be loaded by the oral insertion tool 1, are examples, and the anastomotic portions f1 between the orbicularis oris muscle k1 and facial muscles other than the orbicularis oris muscle k1. A load can be applied to the anastomotic portions other than f2 and f3 by the oral insertion tool 1.
