Description

本発明は、下顎を顔前方側に引き出して睡眠時の気道を確保する気道確保装置及びそれに使用する調節器具に関するものである。更に詳しくは、調節器具を下顎側装着体及び上顎側装着体から取り外すことによって、繰り返し使用することができるようにしたものに関する。   The present invention relates to an airway securing device that secures an airway during sleep by pulling out the lower jaw toward the front side of the face, and an adjusting instrument used therefor. More specifically, the present invention relates to a device that can be used repeatedly by removing the adjusting device from the lower jaw side mounting body and the upper jaw side mounting body.

睡眠時無呼吸症候群（SAS：Sleep Apnea Syndrome）は、夜間、十分な睡眠がとれないため、日中に耐え難い眠気を催したり、集中力の低下を引き起こす原因のひとつとされている。睡眠時無呼吸症候群の対策としては、例えば下顎を正常な噛み合わせ位置より顔前方側へやや引き出すことにより、舌根によって気道が閉塞されることを防止して、睡眠時に無呼吸状態を生じさせないようにする処置が行われている。このための器具としては、例えば本発明者が提案した特許文献１に記載されたものがある。   Sleep Apnea Syndrome (SAS) is considered to be one of the causes of unsatisfactory sleepiness during the day and poor concentration because it cannot sleep enough at night. As a countermeasure for sleep apnea syndrome, for example, by pulling out the lower jaw slightly from the normal meshing position to the front of the face, it prevents the airway from being blocked by the tongue base, so as not to cause an apnea state during sleep The action to make is done. As an instrument for this purpose, for example, there is one described in Patent Document 1 proposed by the present inventor.

特許文献１に記載された「気道確保装置」は、口腔内の上顎側に装着される上顎側装着体と、上顎側装着体とは別体に設けてあり口腔内の下顎側に装着される下顎側装着体とを備え、下顎側装着体と上顎側装着体は、下顎側装着体を上顎側装着体に対して前後へ進退動させることができる無段階調節装置を介在させて連結された構造であり、患者に適した下顎側装着体の引き出し位置の設定が迅速かつ簡単にできるようにしたものである。   The “airway securing device” described in Patent Document 1 is provided separately on the upper jaw side mounting body to be mounted on the upper jaw side in the oral cavity and the upper jaw side mounting body, and is mounted on the lower jaw side in the oral cavity. The lower jaw side attachment body and the upper jaw side attachment body are connected via a stepless adjustment device capable of moving the lower jaw side attachment body forward and backward with respect to the upper jaw side attachment body. The structure is such that the pull-out position of the lower jaw side wearing body suitable for the patient can be set quickly and easily.

また、本発明者は特許文献１に記載されたものにさらに改良を加えて、非特許文献１及び図８に記載された無段階調節装置を採用して、より実用的な気道確保装置を開発している。このタイプの無段階調節装置の基本的な構造の説明は、後述する本発明に係る実施例の説明に譲るが、無段階調節装置は、特許文献１記載のものと基本的な構造は同じでありながら、表面を滑らかな曲面とした金属製の成形部材を使用して、取り扱い性や安全性を高めたものである。   In addition, the present inventor further improved the one described in Patent Document 1, and developed a more practical airway securing device by adopting the stepless adjustment device described in Non-Patent Document 1 and FIG. doing. The description of the basic structure of this type of stepless adjustment device will be given in the description of the embodiment according to the present invention to be described later, but the stepless adjustment device has the same basic structure as that described in Patent Document 1. However, it uses a metal molded member with a smooth curved surface to improve handling and safety.

インターネット＜http://www.med.kurume-u.ac.jp/med/joint/chizai/file/seeds/001_P1-40.pdf＞Internet <http://www.med.kurume-u.ac.jp/med/joint/chizai/file/seeds/001_P1-40.pdf>

しかしながら、非特許文献１と基本的に同等の構成を有する図８に記載された無段階調節装置及びそれを採用した気道確保装置には、次のような課題があった。
すなわち、無段階調節装置を構成している成形部材である基部材８０及びスライド部材８１には、上顎側装着体と下顎側装着体に埋設する取着線材８２が固定されている。上顎側装着体及び下顎側装着体と一体化している各取着線材８２の他端側は、図８に示すように、基部材８０及びスライド部材８１の基端面に設けられている差込孔８３に差し込まれ、外れないように、ろう付部８４により接着されている。 However, the stepless adjustment device shown in FIG. 8 having a configuration basically equivalent to that of Non-Patent Document 1 and the airway securing device employing the same have the following problems.
That is, an attachment wire 82 embedded in the upper jaw side mounting body and the lower jaw side mounting body is fixed to the base member 80 and the slide member 81 which are molding members constituting the stepless adjustment device. As shown in FIG. 8, the other end side of each attachment wire 82 integrated with the upper jaw side mounting body and the lower jaw side mounting body is an insertion hole provided in the base end surface of the base member 80 and the slide member 81. It is bonded by a brazing portion 84 so as to be inserted into 83 and not detached.

このため、基部材８０及びスライド部材８１に対して取り付けられた各取着線材８２は取り替えることができず、一度使用した無段階調節装置は再使用ができないため、例えば特定の患者に対する気道確保装置の使用が終了した後においては、無段階調節装置も上顎側装着体及び下顎側装着体と共に廃棄されていた。   For this reason, since each attachment wire 82 attached with respect to the base member 80 and the slide member 81 cannot be replaced, and the stepless adjustment device once used cannot be reused, for example, an airway securing device for a specific patient. After the use was finished, the stepless adjustment device was also discarded together with the maxillary side mounting body and the mandibular side mounting body.

しかし、前記無段階調節装置を、例えば金属アレルギーを引き起こしにくいとされるチタン等の高価で希少な金属を使用して製造する場合は、製造コストが高くなってしまうため、資源の無駄な使用を排除し、患者の治療費負担を軽減するためにも、無段階調節装置を繰り返し使用することができるように改善することが望まれていた。   However, if the stepless control device is manufactured using expensive and rare metals such as titanium, which are unlikely to cause metal allergies, the manufacturing cost will be high, and wasteful use of resources will be avoided. In order to eliminate and reduce the burden of treatment costs for patients, it has been desired to improve the stepless adjustment device so that it can be used repeatedly.

（作用）
本発明に係る気道確保装置の作用を説明する。なお、ここでは、説明で使用する各構成要件に、後述する実施の形態において各部に付与した符号を対応させて付与するが、この符号は、特許請求の範囲の各請求項に記載した符号と同様に、あくまで内容の理解を容易にするためであって、各構成要件の意味を上記各部に限定するものではない。 (Function)
The operation of the airway securing device according to the present invention will be described. Here, the constituent elements used in the description are assigned in correspondence with the reference numerals given to the respective parts in the embodiments described later. These reference numerals are the same as the reference numerals described in the claims of the claims. Similarly, it is only for the purpose of facilitating understanding of the contents, and the meaning of each component is not limited to the above-described parts.

気道確保装置(A)の上顎側装着体(1)と下顎側装着体(2)を、処置を行う仰臥した患者の口腔内に入れ、上顎側装着体(1)を患者の上顎側の歯と歯茎に嵌め込み、下顎側装着体(2)を下顎側の歯と歯茎に嵌め込む。このとき、上顎と下顎の位置関係をできるだけ自然な状態とし、患者が感じる違和感を最小限とするために、必要であれば取着線材(31,33)を変形させて上顎側装着体(1)と下顎側装着体(2)の位置を調節する。   Place the upper attachment body (1) and lower jaw attachment body (2) of the airway securing device (A) into the oral cavity of the patient who is supine for treatment, and place the upper attachment body (1) on the patient's upper teeth. And the lower jaw side mounting body (2) is inserted into the lower jaw side teeth and gums. At this time, in order to make the positional relationship between the upper jaw and the lower jaw as natural as possible and minimize the uncomfortable feeling felt by the patient, if necessary, the attachment wires (31, 33) are deformed to deform the upper jaw side mounted body (1 ) And mandibular attachment body (2).

調節ねじ(34)を回して、下顎側に嵌め込まれて固定されている下顎側装着体(2)を適当な高さまで引き上げると、患者の舌根部が上がり、気道が確保される。これにより、就寝時のいびきや睡眠時無呼吸症候群の発生を防止することができる。   When the adjustment screw (34) is turned and the lower jaw side attachment body (2) fitted and fixed on the lower jaw side is pulled up to an appropriate height, the tongue base of the patient is raised and the airway is secured. Thereby, snoring at the time of going to bed and the occurrence of sleep apnea syndrome can be prevented.

また、特定の患者に対する使用が終了した後においては、気道確保装置(A)を構成している上顎側装着体(1)と下顎側装着体(2)は不要になるので、取着線材(31,33)を切断し、上顎側装着体(1)及び下顎側装着体(2)と、基部材(32)及びスライド部材(30)を分離する。上顎側装着体(1)と下顎側装着体(2)は、所定の規則に則り廃棄される。   In addition, after the use for a specific patient is completed, the upper jaw side wearing body (1) and the lower jaw side wearing body (2) constituting the airway securing device (A) become unnecessary, so that the attachment wire ( 31, 33) is cut, and the upper jaw side mounting body (1) and lower jaw side mounting body (2) are separated from the base member (32) and the slide member (30). The upper jaw side wearing body (1) and the lower jaw side wearing body (2) are discarded in accordance with a predetermined rule.

上顎側装着体(1)及び下顎側装着体(2)と分離された基部材(32)の通し部(307,308)及びスライド部材(30)の通し部(327,328)から、残っている取着線材を抜き取る。
基部材(32)の通し部(307,308)及びスライド部材(30)の通し部(327,328)に、抜き取った取着線材の代わりに、新しい取着線材(31,33)を差し込み、先端側へは抜けずに止まるようにして装着する。 The remaining attachment wires from the passage portions (307, 308) of the base member (32) and the passage portions (327, 328) of the slide member (30) separated from the upper jaw side attachment body (1) and lower jaw side attachment body (2). Pull out.
Instead of the removed attachment wire, insert a new attachment wire (31, 33) into the passage (307,308) of the base member (32) and the passage (327,328) of the slide member (30). Install it so that it will not come off.

そして、取着線材(31,33)の先部を別の患者用として作製した上顎側装着体１及び下顎側装着体(2)に取り付けることにより、新たな気道確保装置を作製することができる。
このように、気道確保装置(A)の上顎側装着体(1)及び下顎側装着体(2)から取り外した調節器具(3)を、例えば他の患者用として繰り返し使用することができる。 And a new airway securing device can be produced by attaching the tip of the attachment wires (31, 33) to the maxillary side attachment body 1 and the mandibular side attachment body (2) produced for another patient. .
As described above, the adjustment device (3) detached from the upper jaw side mounting body (1) and lower jaw side mounting body (2) of the airway securing device (A) can be repeatedly used for other patients, for example.

本発明は、下顎側装着体と上顎側装着体及び下顎側装着体を上顎側装着体に対して進退動させることができる調節器具を備えた気道確保装置において、調節器具を構成する基部材及びスライド部材に取り付けられ上顎側装着体及び下顎側装着体に接続される各取着線材を、基部材及びスライド部材に対して取り替えることができる。
したがって、例えば特定の患者に対する使用が終了した後において、気道確保装置の下顎側装着体及び上顎側装着体から取り外した調節器具を、他の患者用として繰り返し使用することができる。これにより、例えば材料としてチタン等の高価で希少な素材を使用する場合、資源の無駄な使用を排除することができると共に、患者の治療費負担を軽減することができる。 The present invention relates to an airway securing device including a lower jaw side mounting body, an upper jaw side mounting body, and an adjustment device capable of moving the lower jaw side mounting body forward and backward with respect to the upper jaw side mounting body. Each attachment wire attached to the slide member and connected to the upper jaw side mounting body and the lower jaw side mounting body can be replaced with the base member and the slide member.
Therefore, for example, after the use with respect to a specific patient is completed, the adjustment device removed from the lower jaw side wearing body and the upper jaw side wearing body of the airway securing device can be repeatedly used for other patients. Thereby, for example, when an expensive and rare material such as titanium is used as a material, wasteful use of resources can be eliminated, and the burden of treatment costs on a patient can be reduced.

本発明を図面に示した実施例に基づき詳細に説明する。   The present invention will be described in detail based on embodiments shown in the drawings.

気道確保装置Ａは、上顎側装着体１、下顎側装着体２、調節器具３及びそれらを接続する取着線材３１、３３を備えている。上顎側装着体１は口腔内の上顎側に装着されるものであり、下顎側装着体２は口腔内の下顎側に装着されるものである（図１、図６参照）。   The airway securing device A includes an upper jaw side mounting body 1, a lower jaw side mounting body 2, an adjusting device 3, and attachment wires 31 and 33 connecting them. The upper jaw side mounting body 1 is mounted on the upper jaw side in the oral cavity, and the lower jaw side mounting body 2 is mounted on the lower jaw side in the oral cavity (see FIGS. 1 and 6).

上顎側装着体１と下顎側装着体２はそれぞれ別体に形成されており、実質的に歯や歯茎との間にほぼ隙間がない状態で上顎側や下顎側に嵌った状態で装着できるよう形成されている。上顎側装着体１と下顎側装着体２は、通常、各患者ごとに採取した型に合成樹脂（レジン等）を流し込んで製作される。そして、上顎側装着体１と下顎側装着体２は、それらの前部側に取り付けられている前記調節器具３により連結されている。   The maxilla-side mounting body 1 and the mandibular-side mounting body 2 are formed separately from each other so that they can be mounted in a state of being fitted to the maxillary side or the mandibular side with substantially no gap between the teeth and gums. Is formed. The upper jaw side mounting body 1 and the lower jaw side mounting body 2 are usually manufactured by pouring a synthetic resin (resin or the like) into a mold collected for each patient. And the upper jaw side mounting body 1 and the lower jaw side mounting body 2 are connected by the said adjustment tool 3 attached to those front parts side.

調節器具３は、基部材３２、スライド部材３０及び基部材３２とスライド部材３０をつなぐ調節ねじ３４により構成されている。
また、後で説明するように、基部材３２は取着線材３３により上顎側装着体１に取着され、スライド部材３０は取着線材３１により下顎側装着体２に取着される。 The adjusting instrument 3 includes a base member 32, a slide member 30, and an adjustment screw 34 that connects the base member 32 and the slide member 30.
Further, as will be described later, the base member 32 is attached to the upper jaw side mounting body 1 by the attachment wire member 33, and the slide member 30 is attached to the lower jaw side attachment body 2 by the attachment wire member 31.

（基部材３２）
主に、図４（ａ）、図５を参照する。
基部材３２は、本実施の形態においては合成樹脂で形成されているが、例えば金属アレルギーを引き起こしにくいとされるチタン等、所要の強度を有し安全性に問題がなければ他の材料を採用することもできる。 (Base member 32)
Reference is mainly made to FIG. 4 (a) and FIG.
The base member 32 is formed of a synthetic resin in the present embodiment, but other materials such as titanium, which is unlikely to cause metal allergies, have a required strength and have no safety problems. You can also

基部材３２の外形は、いわば楕円柱形状のものを縦割りにした構造であり、後述するスライド部材３０よりやや長く形成されている（図２を合わせて参照）。基部材３２の合わせ面側（図４（ａ）で下面側）の幅方向中央部には、長さ方向に断面半円形状の通し溝３２１が形成されている。また、通し溝３２１のやや先端寄りには、調節ねじ３４を通す通し孔３２２を有する円筒形状のねじ装着部３２３が形成されている。   The outer shape of the base member 32 is a structure in which an elliptical columnar shape is vertically divided, and is formed slightly longer than a slide member 30 described later (see also FIG. 2). A through groove 321 having a semicircular cross section in the length direction is formed at the center in the width direction on the mating surface side (the lower surface side in FIG. 4A) of the base member 32. A cylindrical screw mounting portion 323 having a through hole 322 through which the adjustment screw 34 is passed is formed slightly near the tip of the through groove 321.

ねじ装着部３２３の通し孔３２２には、調節ねじ３４が通されている。調節ねじ３４は、ねじ部３４０とヘッド部３４２で構成されている。ヘッド部３４２の端面には、六角レンチ用のレンチ孔３４３が形成されている。また、調節ねじ３４は、ヘッド部３４２を図５に示すようにねじ装着部３２３に近接させた位置で、その長さ方向に移動しないようにして、軸周方向へ回転自在に装着されている。   An adjustment screw 34 is passed through the through hole 322 of the screw mounting portion 323. The adjustment screw 34 includes a screw portion 340 and a head portion 342. A wrench hole 343 for a hexagon wrench is formed on the end surface of the head portion 342. Further, the adjustment screw 34 is mounted so as to be rotatable in the axial circumferential direction so as not to move in the length direction at a position where the head portion 342 is close to the screw mounting portion 323 as shown in FIG. .

詳しくは、調節ねじ３４のヘッド部３４２側の端部にねじ山のない径小部３４１（図５参照）が設けられており、また、ねじ装着部３２３の通し孔３２２内部に内ねじ管３２２ａが埋め込まれており、調節ねじ３４を内ねじ管３２２ａにねじ込んで通し孔３２２を貫通し、径小部３４１を内ねじ管３２２ａ内に位置させた構造である。   Specifically, a small-diameter portion 341 (see FIG. 5) without a screw thread is provided at the end of the adjustment screw 34 on the head portion 342 side, and the inner screw tube 322a is provided inside the through hole 322 of the screw mounting portion 323. Is embedded, the adjusting screw 34 is screwed into the inner screw tube 322a, the through hole 322 is penetrated, and the small diameter portion 341 is positioned in the inner screw tube 322a.

これにより、ねじ部３４０と内ねじ管３２２ａが再び螺合しない限り、調節ねじ３４は長さ方向に移動することなく軸左右方向へ回転することができる。
なお、調節ねじ３４をねじ装着部３２３に装着した状態では、ヘッド部３４２の先端面は基部材３２の先端面３２５とほぼ同じ位置になるようにしてある。 Accordingly, as long as the screw portion 340 and the inner screw tube 322a are not screwed again, the adjusting screw 34 can rotate in the left-right direction without moving in the length direction.
In the state where the adjustment screw 34 is mounted on the screw mounting portion 323, the distal end surface of the head portion 342 is positioned substantially at the same position as the distal end surface 325 of the base member 32.

基部材３２には、先端面３２５と基端面３２６を貫通して、通し孔３２７、３２８が平行に形成されている。なお、通し孔３２７、３２８（後述する通し孔３０７、３０８も同様）は、基端面３２６と、基端面３２６を除く他の面（例えば後述する外周面３２４等）を貫通して設けることもできる。
また、先端面３２５側には、通し孔３２７、３２８の各口部をつなぐ収容凹部３２９が形成されている。収容凹部３２９には、後述するように取着線材３３の曲げ部３３０を収めることができる。 In the base member 32, through holes 327 and 328 are formed in parallel through the distal end surface 325 and the proximal end surface 326. The through holes 327 and 328 (the same applies to through holes 307 and 308 described later) can also be provided through the base end surface 326 and other surfaces (for example, an outer peripheral surface 324 described later) other than the base end surface 326. .
In addition, an accommodation recess 329 that connects the mouths of the through holes 327 and 328 is formed on the distal end surface 325 side. The accommodating recess 329 can accommodate the bent portion 330 of the attachment wire 33 as will be described later.

さらに、先端面３２５側には、収容凹部３２９と外周面３２４間を貫通して先端面３２５に通る補助溝３２９ａが形成されている。
また、外周面３２４には、「上」の文字３２４ａが表示されており、この基部材３２が上顎側装着体１に取着される側であることを示している。 Further, an auxiliary groove 329 a that passes through the space between the housing recess 329 and the outer peripheral surface 324 and passes through the tip surface 325 is formed on the tip surface 325 side.
Further, on the outer peripheral surface 324, an “upper” character 324a is displayed, which indicates that the base member 32 is a side to be attached to the upper jaw side mounting body 1.

このように、基部材３２には「上」の文字３２４ａが、後述するスライド部材３０には「下」の文字３０４ａが表されていることにより、後で説明するように調節器具３を再使用するときに、上顎側装着体１または下顎側装着体２に対する取り付け間違いを防止することができる。   In this way, the upper member 324a is represented on the base member 32, and the lower member 304a is represented on the slide member 30 described later, so that the adjusting device 3 can be reused as will be described later. In doing so, it is possible to prevent an attachment error with respect to the upper jaw side mounting body 1 or the lower jaw side mounting body 2.

また、外周面３２４の幅方向の一端部（図４（ａ）で左側端部）には、後述する指標３００と位置が重なる目盛り３２０が長さ方向に表示されている。基部材３２側の目盛り３２０に対するスライド部材３０側の指標３００の位置を確認しておくことで、例えば気道確保装置Ａを洗浄した後で再度患者に装着する場合等、スライド部材３０と基部材３２の位置関係を洗浄前の状態に簡単に復帰させることができる。   In addition, a scale 320 whose position overlaps with an index 300 described later is displayed in the length direction at one end portion in the width direction of the outer peripheral surface 324 (the left end portion in FIG. 4A). By confirming the position of the index 300 on the slide member 30 side with respect to the scale 320 on the base member 32 side, for example, when the airway securing device A is washed and attached to the patient again, the slide member 30 and the base member 32 are used. Can be easily restored to the state before cleaning.

基部材３２の通し孔３２７、３２８には、Ｕ字形状に曲げられた金属製（鋼線、ワイヤ等）の取着線材３３が収容凹部３２９側から差し込まれて装着されている。取着線材３３の曲げ部３３０は、収容凹部３２９内に収まり、先端面３２５からは突出しないようにしてある。また、曲げ部３３０は収容凹部３２９の奥端部（符号省略）に掛かって止まり、取着線材３３は上顎側装着体１側へ抜け外れることはない。   In the through holes 327, 328 of the base member 32, a metal attachment wire 33 (steel wire, wire, etc.) bent into a U-shape is inserted and attached from the housing recess 329 side. The bent portion 330 of the attachment wire 33 is accommodated in the housing recess 329 so as not to protrude from the distal end surface 325. Further, the bent portion 330 is stopped by being hooked on the rear end portion (reference number omitted) of the housing recess 329, and the attachment wire 33 does not come off to the upper jaw side mounting body 1 side.

取着線材３３の二本に分かれた各先端側は、図１に示すように上顎側装着体１の前部側に埋設するようにして固定されている。なお、取着線材３３は、やや強い力で変形させると、その後もその形状を維持する塑性変形をするようになっており、これにより基部材３２と上顎側装着体１との角度または方向（向き）を所要の範囲内で任意に調節することができる。   The distal ends of the attachment wire 33 divided into two are fixed so as to be embedded in the front side of the maxillary side mounting body 1 as shown in FIG. In addition, if the attachment wire 33 is deformed with a slightly strong force, it will be plastically deformed to maintain its shape thereafter, whereby the angle or direction between the base member 32 and the upper jaw side mounting body 1 ( (Direction) can be arbitrarily adjusted within a required range.

また、取着線材３３は各通し孔３２７、３２８から出た部分で外側へ曲げられており、取着線材３３に荷重がかかったときに取着線材３３が収容凹部３２９側へ動かないように止めている。なお、後述するスライド部材３０は、使用において取着線材３１に対して収容凹部３０９側へ抜ける方向の荷重は実質的に作用しないので、取着線材３１に取着線材３３のような曲げ加工は施されていない。   Further, the attachment wire 33 is bent outward at the portions coming out of the through holes 327 and 328 so that the attachment wire 33 does not move toward the housing recess 329 when a load is applied to the attachment wire 33. Stopped. Since the slide member 30 to be described later does not substantially act on the attachment wire 31 in the direction of coming out toward the housing recess 309 in use, the bending process such as the attachment wire 33 is not performed on the attachment wire 31. Not given.

（スライド部材３０）
主に、図４（ｂ）、図５を参照する。
スライド部材３０は、後述する雌ねじ体３０２を除いて合成樹脂で形成されている。スライド部材３０の外形は、前記基部材３２と同様に楕円柱形状のものを縦割りにした構造であり、合わせ面側（図４（ｂ）で上面側）の幅方向中央部には、長さ方向に断面半円形状の通し溝３０１が形成されている。また、通し溝３０１の中間部には、調節ねじ３４を螺合する雌ねじ体３０２がインサートされたほぼ円筒形状のねじ螺合部３０３が形成されている。 (Slide member 30)
Referring mainly to FIGS. 4B and 5.
The slide member 30 is formed of a synthetic resin except for a female screw body 302 described later. The outer shape of the slide member 30 is a structure in which an elliptical columnar shape is vertically divided in the same manner as the base member 32, and a long central portion in the width direction on the mating surface side (the upper surface side in FIG. 4B) is long. A through groove 301 having a semicircular cross section is formed in the vertical direction. In addition, a substantially cylindrical screw threaded portion 303 into which a female screw body 302 into which the adjusting screw 34 is threaded is inserted is formed at an intermediate portion of the through groove 301.

スライド部材３０の幅方向中央部かつ外周面３０４と通し溝３０１の間には、先端面３０５と基端面３０６間を長さ方向に貫通した通し孔３０７、３０８が平行に形成されている。先端面３０５側には、通し孔３０７、３０８の各口部をつなぐ収容凹部３０９が形成されている。収容凹部３０９には、取着線材３１の曲げ部３１０を収めることができる。   Through holes 307 and 308 penetrating between the front end surface 305 and the base end surface 306 in the length direction are formed in parallel in the width direction center of the slide member 30 and between the outer peripheral surface 304 and the through groove 301. On the front end surface 305 side, an accommodation recess 309 that connects the mouths of the through holes 307 and 308 is formed. The bending portion 310 of the attachment wire 31 can be accommodated in the accommodation recess 309.

また、先端面３０５側には、収容凹部３０９と外周面３０４間を貫通して先端面３０５に通る補助溝３０９ａが形成されている。外周面３０４には、「下」の文字３０４ａが表示されており、このスライド部材３０が下顎側装着体２に取着される側であることを示している。外周面３０４の幅方向の一端部（図４（ｂ）で左側端部）には、長さ方向の所要位置に三角形の指標３００が表示されている。   In addition, an auxiliary groove 309 a that passes through the space between the housing recess 309 and the outer peripheral surface 304 and passes through the distal end surface 305 is formed on the distal end surface 305 side. On the outer peripheral surface 304, “lower” characters 304 a are displayed, indicating that the slide member 30 is the side to be attached to the lower jaw side mounting body 2. At one end in the width direction of the outer peripheral surface 304 (the left end in FIG. 4B), a triangular index 300 is displayed at a required position in the length direction.

スライド部材３０の通し孔３０７、３０８には、Ｕ字形状に曲げられた取着線材３１が収容凹部３０９側から差し込まれて装着されている。取着線材３１の曲げ部３１０は、先端面３０５から突出しないように収容凹部３０９に収めることができる。また、曲げ部３１０は収容凹部３０９の奥端部（符号省略）に掛かって止まり、取着線材３１は下顎側装着体２側へ抜け外れることはない。   In the through holes 307 and 308 of the slide member 30, the attachment wire 31 bent into a U shape is inserted and attached from the housing recess 309 side. The bent portion 310 of the attachment wire 31 can be housed in the housing recess 309 so as not to protrude from the distal end surface 305. Further, the bent portion 310 is caught by the back end portion (not shown) of the housing recess 309 and stopped, and the attachment wire 31 does not come off to the lower jaw side mounting body 2 side.

取着線材３１の二本に分かれた各先端側は、図１に示すように下顎側装着体２の前部側に埋設するようにして固定されている。なお、取着線材３１は、前記取着線材３３と同様に塑性変形をするので、スライド部材３０と下顎側装着体２との角度または方向（向き）を所要の範囲内で任意に調節することができる。   Each tip side divided into two of the attachment wires 31 is fixed so as to be embedded in the front side of the lower jaw side mounting body 2 as shown in FIG. Since the attachment wire 31 is plastically deformed similarly to the attachment wire 33, the angle or direction (orientation) between the slide member 30 and the lower jaw side mounting body 2 can be arbitrarily adjusted within a required range. Can do.

気道確保装置Ａは、前記上顎側装着体１に基部材３２を取り付けたものと、下顎側装着体２にスライド部材３０を取り付けたものを組み合わせて使用される。すなわち、図１ないし図３及び図５に示すように基部材３２とスライド部材３０を向かい合わせ、基部材３２側の調節ねじ３４をスライド部材３０側の雌ねじ体３０２に螺合する。そして、調節ねじ３４を回せば、スライド部材３０と基部材３２を調節ねじ３４の軸線方向に相対的にスライドさせることができる。   The airway securing device A is used in combination of a device in which the base member 32 is attached to the upper jaw side mounting body 1 and a device in which the slide member 30 is attached to the lower jaw side mounting body 2. That is, as shown in FIGS. 1 to 3 and 5, the base member 32 and the slide member 30 face each other, and the adjustment screw 34 on the base member 32 side is screwed into the female screw body 302 on the slide member 30 side. When the adjustment screw 34 is turned, the slide member 30 and the base member 32 can be relatively slid in the axial direction of the adjustment screw 34.

（作用）
図１ないし図５及び図６、図７を参照して気道確保装置Ａの作用を説明する。
気道確保装置Ａは、図１に示すように組み上げておく。基部材３２とスライド部材３０の位置関係は、例えば図５に示すように標準的な位置に設定しておいてもよいが、患者個人に合うように、図５とは異なる位置関係になるように適宜調節しておくこともできる。 (Function)
The operation of the airway securing device A will be described with reference to FIGS. 1 to 5, 6 and 7.
The airway securing device A is assembled as shown in FIG. The positional relationship between the base member 32 and the slide member 30 may be set at a standard position as shown in FIG. 5, for example. However, the positional relationship is different from that in FIG. It can also be adjusted appropriately.

そして、図６に示すように、気道確保装置Ａの上顎側装着体１と下顎側装着体２を、処置を行う仰臥した患者の口腔内に入れ、上顎側装着体１を患者の上顎側の歯と歯茎に嵌め込み、下顎側装着体２を下顎側の歯と歯茎に嵌め込む。このとき、上顎と下顎の位置関係をできるだけ自然な状態とし、患者が感じる違和感を最小限とするために、必要であれば取着線材３１、３３を変形させて上顎側装着体１と下顎側装着体２の位置を調節する。   Then, as shown in FIG. 6, the upper jaw side mounting body 1 and the lower jaw side mounting body 2 of the airway securing device A are placed in the oral cavity of the patient who is supine for treatment, and the upper jaw side mounting body 1 is placed on the upper jaw side of the patient. It fits into teeth and gums, and the lower jaw side mounting body 2 is fitted into the lower jaw side teeth and gums. At this time, in order to make the positional relationship between the upper jaw and the lower jaw as natural as possible and minimize the uncomfortable feeling felt by the patient, if necessary, the attachment wires 31 and 33 are deformed to deform the upper jaw side mounting body 1 and the lower jaw side. The position of the mounting body 2 is adjusted.

この状態で調節ねじ３４を回して、下顎側に嵌め込まれて固定されている下顎側装着体２を適当な高さまで引き上げる。なお、調節ねじ３４を回すと基部材３２とスライド部材３０は相対的にスライドするが、上顎側装着体１が嵌め込まれて固定されている上顎側は実質的に動かない固定側となるので、調節ねじ３４を回すとスライド部材３０に取着されている下顎側装着体２が上下に移動する。すなわち、調節ねじ３４を回すことにより、患者の下顎側を出入り方向（患者が仰臥している場合では上下方向）へ移動させることができる。   In this state, the adjustment screw 34 is turned to raise the lower jaw side mounting body 2 fitted and fixed to the lower jaw side to an appropriate height. When the adjustment screw 34 is turned, the base member 32 and the slide member 30 slide relative to each other, but the upper jaw side on which the upper jaw side mounting body 1 is fitted and fixed becomes a fixed side that does not substantially move. When the adjustment screw 34 is turned, the lower jaw side mounting body 2 attached to the slide member 30 moves up and down. That is, by turning the adjusting screw 34, the lower jaw side of the patient can be moved in the direction of entering and exiting (up and down direction when the patient is supine).

前記したように下顎側装着体２を適当な高さまで引き上げることにより、患者の舌根部４が上がり、気道５が確保される。これにより、就寝時のいびきや睡眠時無呼吸症候群の発生を防止することができる。   As described above, the tongue base portion 4 of the patient is raised and the airway 5 is secured by lifting the lower jaw side mounting body 2 to an appropriate height. Thereby, snoring at the time of going to bed and the occurrence of sleep apnea syndrome can be prevented.

また、特定の患者に対する使用が終了した後においては、気道確保装置Ａを構成している上顎側装着体１と下顎側装着体２は不要になるので、図７に示すように取着線材３１、３３を切断し、上顎側装着体１及び下顎側装着体２と、基部材３２及びスライド部材３０を分離する（図７：上図参照）。上顎側装着体１と下顎側装着体２は、所定の規則に則り廃棄される。   Further, after the use with respect to a specific patient is completed, the upper jaw side mounting body 1 and the lower jaw side mounting body 2 constituting the airway securing device A are not necessary, so that the attachment wire 31 as shown in FIG. , 33 are separated, and the upper jaw side mounting body 1 and the lower jaw side mounting body 2 are separated from the base member 32 and the slide member 30 (see FIG. 7: upper diagram). The upper jaw side mounting body 1 and the lower jaw side mounting body 2 are discarded in accordance with a predetermined rule.

上顎側装着体１及び下顎側装着体２と分離された基部材３２の通し孔３２７、３２８及びスライド部材３０の通し孔３０７、３０８から、残っている取着線材３３ａ、３１ａを抜き取る（図７：中図参照）。このとき、基部材３２及びスライド部材３０のそれぞれの補助溝３２９ａ、３０９ａにピン等を差し込み、取着線材３３ａ、３１ａの曲げ部３３０、３１０に引っ掛けるようにすると抜き取りがしやすい。   The remaining attachment wires 33a and 31a are extracted from the through holes 327 and 328 of the base member 32 and the through holes 307 and 308 of the slide member 30 separated from the upper jaw side mounting body 1 and the lower jaw side mounting body 2 (FIG. 7). : Refer to the middle figure). At this time, if a pin or the like is inserted into each of the auxiliary grooves 329a and 309a of the base member 32 and the slide member 30 and is hooked on the bent portions 330 and 310 of the attachment wires 33a and 31a, the extraction is easy.

取着線材３３ａ、３１ａを抜き取った基部材３２及びスライド部材３０は、再度使用することができる。すなわち、基部材３２の通し孔３２７、３２８及びスライド部材３０の通し孔３０７、３０８に、前記抜き取った取着線材３３ａ、３１ａの代わりに、新しい取着線材３３、３１を差し込み、各曲げ部３３０、３１０が収容凹部３２９、３０９内で止まるようにして装着し（図７：下図参照）、取着線材３３、３１の先部を別の患者用として作製した上顎側装着体１及び下顎側装着体２に取り付けることにより、新たな気道確保装置Ａを作製することができる。   The base member 32 and the slide member 30 from which the attachment wires 33a and 31a have been extracted can be used again. That is, instead of the extracted attachment wires 33a and 31a, the new attachment wires 33 and 31 are inserted into the through holes 327 and 328 of the base member 32 and the through holes 307 and 308 of the slide member 30, and the bent portions 330 are inserted. , 310 is fixed so as to stop in the receiving recesses 329 and 309 (see FIG. 7: the lower figure), and the upper end attachment body 1 and the lower jaw side attachment in which the tip portions of the attachment wires 33 and 31 are prepared for another patient. By attaching to the body 2, a new airway securing device A can be produced.

このように、気道確保装置Ａの上顎側装着体１及び下顎側装着体２から取り外した調節器具３を、例えば他の患者用として繰り返し使用することができる。
また、調節器具３の材料をチタンとした場合であれば、高価で希少な資源の無駄な使用を排除することができると共に、患者の治療費負担を軽減することができる。 Thus, the adjustment instrument 3 removed from the upper jaw side mounting body 1 and the lower jaw side mounting body 2 of the airway securing device A can be repeatedly used for other patients, for example.
Moreover, if the material of the adjusting device 3 is titanium, it is possible to eliminate useless use of expensive and scarce resources and to reduce the burden of treatment costs for the patient.
