Description

本発明は、遺体の口が開放したままになるのを防止する遺体用口開放防止具に関する。   [Technical Field] The present invention relates to a body opening prevention tool for preventing a body from being left open.

一般に、人間が死亡すると、筋肉が一旦弛緩した後、死後硬直が始まる。従って、死後、遺体を仰向けにしていると、頬及びその周辺の筋肉が弛緩することによって、図１５に示すように、下顎が上顎から離れて口が開放した状態となり、その状態で死後硬直が始まって口が開いたままとなるので、遺族等から見たとき、好ましいものとは言えない。   In general, when a human dies, after the muscles have relaxed, stiffness begins after death. Therefore, when the body is turned on its back after death, the muscles in the cheeks and the surrounding area relax, resulting in a state where the lower jaw is separated from the upper jaw and the mouth is opened, and in that state the post-mortem stiffness is Since it starts and the mouth remains open, it is not preferable when viewed from the bereaved family.

そこで、例えば、特許文献１に開示されている下顎保持具が用いられることがある。この下顎保持具は、下顎に当てる下顎当て部と、下顎当て部から床面まで延びるように形成された脚部とを備えており、使用時には、下顎当て部を下顎に当てて口を閉じさせてから脚部により下顎を支えて上顎から離れないようにする。
特開２００２−１１３０５６号公報 Therefore, for example, a lower jaw holder disclosed in Patent Document 1 may be used. This lower jaw holder has a lower jaw rest that touches the lower jaw and a leg that is formed to extend from the lower jaw rest to the floor surface. Support the lower jaw with the legs and keep it away from the upper jaw.
JP 2002-113056 A

ところで、特許文献１の保持具のように遺体の下顎に当てて使用するものは目立ち易いので、例えば納棺時及びそれ以後の葬儀の際には取り外される。下顎保持具を取り外してしまうと、死後硬直から時間が経過して死後硬直の状態が次第に解けていくと、下顎が上顎から離れていき、再び口が開放してしまうことがある。   By the way, what is used on the lower jaw of the corpse, such as the holder of Patent Document 1, is easily noticeable, and is removed, for example, at the time of delivery and after the funeral. If the mandibular retainer is removed, as time elapses from post-mortem stiffness and the post-mortem stiff state gradually dissolves, the lower jaw may move away from the upper jaw and the mouth may open again.

本発明は斯かる点に鑑みてなされたものであり、その目的とするところは、遺体の口が開放したままになるのを目立たないように防止できるようにすることにある。   The present invention has been made in view of such a point, and an object of the present invention is to prevent the body's mouth from being left open.

上記目的を達成するために、本発明では、口腔内において口の開放を防止できるようにした。   In order to achieve the above object, in the present invention, opening of the mouth can be prevented in the oral cavity.

具体的には、第１の発明では、遺体の口が開放したままになるのを防止する遺体用口開放防止具であって、遺体の口腔内に導入されて上顎と下顎とを接近させるように構成されているものとする。   Specifically, in the first invention, a corpse mouth opening prevention device for preventing the corpse's mouth from being left open, which is introduced into the corpse's mouth so that the upper jaw and the lower jaw are brought close to each other. It is assumed that

この構成によれば、遺体用口開放防止具を遺体の口腔内に導入して口が開放したままになるのを防止することが可能になるので、遺体用口開放防止具が見えにくくなる。   According to this configuration, it is possible to prevent the mouth opening prevention tool for a corpse from being seen by introducing the body opening prevention tool into the oral cavity of the corpse, so that the mouth remains open.

第２の発明では、第１の発明において、上顎の歯に係合する上歯係合部と、下顎の歯に係合する下歯係合部とを備えている構成とする。   In 2nd invention, it is set as the structure provided in the 1st invention with the upper-tooth engaging part engaged with the teeth of an upper jaw, and the lower-tooth engaging part engaged with the teeth of a lower jaw.

この構成によれば、上歯係合部を上顎の歯に係合させるとともに、下歯係合部を下顎の歯に係合させることで、上顎と下顎とが接近した状態で保持される。   According to this configuration, the upper teeth and the lower jaw are held close to each other by engaging the upper teeth engaging portion with the teeth of the upper jaw and engaging the lower teeth engaging portion with the teeth of the lower jaw.

第３の発明では、第２の発明において、各係合部は、歯の表側に接触する表側接触部と、歯の裏側に接触する裏側接触部とを備え、上記表側及び裏側接触部により歯を表裏方向に挟持する構成とする。   According to a third aspect, in the second aspect, each engagement portion includes a front side contact portion that contacts the front side of the tooth and a back side contact portion that contacts the back side of the tooth, and the teeth are formed by the front side and the back side contact portion. Is configured to be sandwiched in the front and back direction.

この構成によれば、各係合部の表側及び裏側接触部の間に歯を差し込んでいくと、表側及び裏側接触部が歯を挟持する。これにより、各係合部が歯に係合した状態となる。   According to this configuration, when the teeth are inserted between the front side and the back side contact portions of the respective engaging portions, the front side and the back side contact portions sandwich the teeth. Thereby, each engaging part will be in the state engaged with the tooth | gear.

第４の発明では、第３の発明において、表側及び裏側接触部の少なくとも一方は他方に接離する方向に弾性変形する構成とする。   According to a fourth invention, in the third invention, at least one of the front side and the back side contact portions is elastically deformed in a direction contacting and separating from the other.

この構成によれば、表側及び裏側接触部の間に歯を差し込んだ際に、その歯の形状や表裏方向の寸法に応じて両接触部の間隔が変化して差し込まれた歯に対応するようになる。   According to this configuration, when a tooth is inserted between the front side and the back side contact portion, the distance between both contact portions is changed according to the shape of the tooth and the size in the front and back direction so as to correspond to the inserted tooth. become.

第５の発明では、第３または４の発明において、表側及び裏側接触部の少なくとも一方には、歯に対する滑りを抑止する滑り止め部が設けられている構成とする。   According to a fifth invention, in the third or fourth invention, at least one of the front side and the back side contact part is provided with a non-slip part for preventing slipping on the teeth.

この構成によれば、表側及び裏側接触部の間に一旦差し込んだ歯が両接触部の間から抜け難くなる。   According to this configuration, the teeth once inserted between the front and back contact portions are difficult to come out from between both contact portions.

第６の発明では、第２から５のいずれか１つの発明において、上歯及び下歯係合部は、隣り合う複数の歯に係合する構成とする。   In a sixth invention, in any one of the second to fifth inventions, the upper tooth and lower tooth engaging portions are configured to engage with a plurality of adjacent teeth.

この構成によれば、上歯係合部が上顎の複数の歯に係合することになるので、上歯係合部が歯から離脱し難くなる。下歯係合部も同様に下顎の歯から離脱し難くなる。   According to this configuration, since the upper tooth engaging portion engages with the plurality of teeth of the upper jaw, it is difficult for the upper tooth engaging portion to be detached from the teeth. Similarly, the lower tooth engaging portion is difficult to detach from the lower teeth.

第１の発明によれば、遺体用口開放防止具を遺体の口腔内に導入した状態で口が開放したままになるのを防止することができるので、遺体用口開放防止具が目立つことはない。これにより、納棺時及び葬儀の際に遺体用口開放防止具を取り外すことなく、口を確実に閉じさせておくことができる。   According to the first invention, it is possible to prevent the mouth from being left open while the body opening preventive device is introduced into the body's mouth, so that the body opening preventive device is conspicuous. Absent. Thus, the mouth can be securely closed without removing the body opening preventer at the time of payment or during the funeral.

第２の発明によれば、上歯係合部と下歯係合部とを設けたので、各係合部を上歯及び下歯に係合させる作業を行うだけで遺体の口が開かないようにすることができ、作業性を良好にすることができる。   According to the second invention, since the upper tooth engaging part and the lower tooth engaging part are provided, the mouth of the body is not opened only by performing the operation of engaging each engaging part with the upper tooth and the lower tooth. Thus, workability can be improved.

第３の発明によれば、各係合部は、歯の表側に接触する表側接触部と、裏側に接触する裏側接触部とを備えており、表側及び裏側接触部により歯を挟持するようにしたので、歯を表側及び裏側接触部の間に差し込むという簡単な作業で各係合部を歯に係合させることができ、作業性をより一層良好にすることができる。   According to 3rd invention, each engaging part is provided with the front side contact part which contacts the front side of a tooth | gear, and the back side contact part which contacts a back side, and pinches | interposes a tooth | gear with a front side and a back side contact part. Therefore, each engagement part can be engaged with the tooth by a simple operation of inserting the tooth between the front side and the back side contact part, and workability can be further improved.

第４の発明によれば、表側及び裏側接触部の少なくとも一方が他方に接離する方向に弾性変形するので、表側及び裏側接触部の間隔が、これら両接触部で挟持する歯に対応するようになる。これにより、表側及び裏側接触部が歯の表側及び裏側にそれぞれ確実に接触して歯をしっかりと挟持することができる。   According to the fourth aspect of the invention, at least one of the front side and the back side contact portion is elastically deformed in a direction in which the front side and the back side contact portion are in contact with and separated from each other. become. Thereby, a front side and a back side contact part can contact the front side and back side of a tooth reliably, respectively, and can hold a tooth | gear firmly.

第５の発明によれば、表側及び裏側接触部の少なくとも一方に滑り止め部を設けたので、接触部の間から歯が抜け難くなり、口が不意に開放してしまうのを未然に防止できる。   According to the fifth invention, since the anti-slip portion is provided on at least one of the front side and the back side contact portion, it is difficult to prevent the teeth from coming out from between the contact portions and to open the mouth unexpectedly. .

第６の発明によれば、上歯係合部が上顎の歯から離脱し難くなるとともに、下歯係合部が下顎の歯から離脱し難くなるので、口が不意に開放してしまうのを未然に防止できる。   According to the sixth aspect of the invention, the upper tooth engaging portion is less likely to be detached from the upper jaw teeth, and the lower tooth engaging portion is less likely to be detached from the lower jaw teeth. It can be prevented beforehand.

以下、本発明の実施形態を図面に基づいて詳細に説明する。尚、以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものではない。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 3, the holding member 2 has a shape close to an H shape in front view, and the upper portion (the upper portion in FIG. 3) is the molar 107 a of the upper jaw 101 (shown in FIGS. 5 and 6). ) Are engaged with each other, and the lower part (the lower part in the figure) is the lower tooth engaging part 20 with which the molar tooth 108a of the lower jaw 102 is engaged. Furthermore, the holding member 2 includes a connecting plate portion 30 for connecting and integrating the engaging portions 10 and 20 in addition to the upper tooth engaging portion 10 and the lower tooth engaging portion 20.

上歯係合部１０は、図４にも示すように、上方に開放しており、図５に示すように上顎１０１の大臼歯１０７ａが２本差し込まれるようになっている。図３及び図４に示すように、上歯係合部１０は、上顎１０１の大臼歯１０７ａの表側に接触する上歯表側接触部１１と、裏側に接触する上歯裏側接触部１２とで構成されている。下歯係合部２０は、下方に開放しており、下顎１０２の大臼歯１０８ａが２本差し込まれるようになっている。下歯係合部２０は、下顎１０２の大臼歯１０８ａの表側に接触する下歯表側接触部２１と、裏側に接触する下歯裏側接触部２２とで構成されている。これら接触部１１，１２，２１，２２及び連結板部３０は、弾性変形可能な樹脂材により一体成形されている。この樹脂材としては、焼却した際に有害ガスが発生しない周知の樹脂材が好ましいが、これに限られるものではなく、例えば、ポリアミド系樹脂（ＰＡ、ナイロン）、ポリカーボネート（ＰＣ）、ポリプロピレン（ＰＰ）、ポリエチレン（ＰＥ）等が挙げられる。   As shown in FIG. 4, the upper tooth engaging portion 10 is opened upward, and two molars 107a of the upper jaw 101 are inserted as shown in FIG. As shown in FIGS. 3 and 4, the upper tooth engaging portion 10 includes an upper tooth front side contact portion 11 that contacts the front side of the molar tooth 107 a of the upper jaw 101 and an upper tooth back side contact portion 12 that contacts the back side. Has been. The lower tooth engaging portion 20 is opened downward, and two molars 108a of the lower jaw 102 are inserted. The lower tooth engaging portion 20 includes a lower tooth front side contact portion 21 that contacts the front side of the molar tooth 108a of the lower jaw 102, and a lower tooth back side contact portion 22 that contacts the back side. The contact portions 11, 12, 21, 22 and the connecting plate portion 30 are integrally formed of an elastically deformable resin material. The resin material is preferably a well-known resin material that does not generate harmful gases when incinerated, but is not limited to this. For example, polyamide resin (PA, nylon), polycarbonate (PC), polypropylene (PP ), Polyethylene (PE) and the like.

連結板部３０は矩形状をなしている。連結板部３０の厚みは、０．５ｍｍ以上２．０ｍｍ以下の範囲で設定されている。連結板部３０の厚みが薄い方が、上側の歯１０７と下側の歯１０８を接近させることができるので好ましい。また、連結板部３０の長手方向の寸法（歯の並び方向に対応する寸法）は、例えば、成人の大臼歯１０７ａ、１０８ａの幅の２倍程度の約２０ｍｍに設定されているが、これに限らず、５ｍｍ以上５０ｍｍの範囲内で任意の寸法に設定することが可能である。連結板部３０の幅寸法（歯の表裏方向の寸法）は、５ｍｍ以上２０ｍｍ以下の範囲で設定されている。   The connecting plate part 30 has a rectangular shape. The thickness of the connecting plate part 30 is set in the range of 0.5 mm or more and 2.0 mm or less. The one where the thickness of the connecting plate part 30 is thinner is preferable because the upper teeth 107 and the lower teeth 108 can be brought close to each other. In addition, the longitudinal dimension of the connecting plate portion 30 (the dimension corresponding to the tooth arrangement direction) is set to about 20 mm, which is about twice the width of the adult molars 107a and 108a, for example. Not limited to this, it is possible to set an arbitrary dimension within a range of 5 mm to 50 mm. The width dimension (dimension in the front and back direction of the teeth) of the connecting plate part 30 is set in the range of 5 mm or more and 20 mm or less.

上歯表側接触部１１は、連結板部３０の幅方向一縁部から該連結板部３０の厚み方向に突出する板状をなし、また、上歯裏側接触部１２は、連結板部３０の幅方向の他縁部から同様に突出する板状をなしており、これら表側接触部１１と裏側接触部１２とは対向している。表側接触部１１は、裏側接触部１２に接離する方向に弾性変形して撓み、また、裏側接触部１２は、表側接触部１１に接離する方向に弾性変形して撓むようになっている。   The upper tooth front side contact portion 11 has a plate shape that protrudes in the thickness direction of the connection plate portion 30 from one edge in the width direction of the connection plate portion 30, and the upper tooth back side contact portion 12 corresponds to the connection plate portion 30. It has a plate shape that similarly projects from the other edge in the width direction, and the front side contact portion 11 and the back side contact portion 12 face each other. The front-side contact portion 11 is elastically deformed and bent in a direction in which the front-side contact portion 12 is in contact with and separated from the back-side contact portion 12.

上歯表側接触部１１及び上歯裏側接触部１２の厚みは、連結板部３０の厚みと同程度に設定されているが、連結板部３０よりも厚くしてもよいし、薄くしてもよい。上歯表側接触部１１の突出方向の寸法は、５ｍｍ以上１０ｍｍ以下の範囲で設定されている。図７にも示すように、上歯表側接触部１１の長手方向（連結板部３０の長手方向）の寸法は、連結板部３０の長手方向の寸法と略同じに設定されている。   Although the thickness of the upper tooth front side contact part 11 and the upper tooth back side contact part 12 is set to the same level as the thickness of the connecting plate part 30, it may be thicker or thinner than the connecting plate part 30. Good. The dimension of the upper tooth front side contact portion 11 in the protruding direction is set in the range of 5 mm to 10 mm. As shown also in FIG. 7, the longitudinal dimension of the upper tooth front contact portion 11 (longitudinal direction of the connecting plate portion 30) is set to be substantially the same as the longitudinal dimension of the connecting plate portion 30.

上歯表側接触部１１は、突出方向先端に近づくほど上歯裏側接触部１２に接近するように傾斜している。上歯表側接触部１１の先端縁には、上歯裏側接触部１２へ向けて突出して先端縁に沿って延びる突条部（滑り止め部）１１ａが形成されている。突条部１１ａの突出高さは１ｍｍ以上が好ましい。突条部１１ａは、詳細は後述するが、大臼歯１０７ａの根に近い部分に当たるようになっている。   The upper tooth front side contact portion 11 is inclined so as to approach the upper tooth back side contact portion 12 as it approaches the front end in the protruding direction. At the tip edge of the upper tooth front side contact portion 11, a ridge portion (slip prevention portion) 11 a that protrudes toward the upper tooth back side contact portion 12 and extends along the tip edge is formed. The protrusion height of the protrusion 11a is preferably 1 mm or more. Although the details of the protrusion 11a will be described later, the protrusion 11a hits a portion close to the root of the molar 107a.

上歯裏側接触部１２は、上歯表側接触部１１と同形状となっており、その突出方向先端に近づくほど上歯表側接触部１１に接近するように傾斜している。上歯裏側接触部１２の先端縁には、上歯表側接触部１１の突条部１１ａへ向けて突出して該突条部１１ａと同様に延びる突条部（滑り止め部）１２ａが形成されている。   The upper tooth back side contact portion 12 has the same shape as the upper tooth front side contact portion 11 and is inclined so as to approach the upper tooth front side contact portion 11 as it approaches the tip end in the protruding direction. At the tip edge of the upper tooth back side contact portion 12, a ridge portion (slip prevention portion) 12a that protrudes toward the ridge portion 11a of the upper tooth front side contact portion 11 and extends in the same manner as the ridge portion 11a is formed. Yes.

つまり、上歯表側接触部１１と上歯裏側接触部１２との間隔は、突出方向先端に近づくほど狭くなっており、両接触部１１，１２の先端部間の間隔は、差し込まれる大臼歯１０７ａの表裏方向の寸法よりも短く設定されている。   That is, the distance between the upper tooth front side contact part 11 and the upper tooth back side contact part 12 becomes narrower as it approaches the tip in the protruding direction, and the distance between the tip parts of both contact parts 11 and 12 is inserted molar 107a. It is set shorter than the dimension in the front and back direction.

下歯表側接触部２１は、連結板部３０の幅方向一縁部から上歯表側接触部１１と反対方向に突出する板状をなし、また、下歯裏側接触部２２は、連結板部３０の幅方向の他縁部から同様に突出する板状をなしており、表側接触部２１と裏側接触部２２とは対向している。下歯表側接触部２１及び下歯裏側接触部２２は、上歯表側接触部１１及び下歯表側接触部１２と同形状であり、突条部（滑り止め部）２１ａ、２２ａをそれぞれ有している。下歯表側接触部２１と下歯裏側接触部２２とは、上歯表側接触部１１と上歯裏側接触部１２と同様に弾性変形するようになっている。   The lower tooth front side contact portion 21 has a plate shape projecting in the opposite direction to the upper tooth front side contact portion 11 from one widthwise edge portion of the connecting plate portion 30, and the lower tooth back side contact portion 22 is connected to the connecting plate portion 30. The front-side contact portion 21 and the back-side contact portion 22 face each other. The lower tooth front side contact part 21 and the lower tooth back side contact part 22 have the same shape as the upper tooth front side contact part 11 and the lower tooth front side contact part 12, and have protrusions (slip prevention parts) 21a and 22a, respectively. Yes. The lower tooth front contact portion 21 and the lower tooth back contact portion 22 are elastically deformed in the same manner as the upper tooth front contact portion 11 and the upper tooth back contact portion 12.

また、下歯表側接触部２１と下歯裏側接触部２２とは上歯表側接触部１１と上歯裏側接触部１２と同様に傾斜しており、よって、上記下歯表側接触部２１と下歯裏側接触部２２との間隔は、連結板部３０から離れるほど狭くなっている。両接触部２１，２２の先端部間の間隔は、差し込まれる大臼歯１０８ａの表裏方向の寸法よりも短く設定されている。   Further, the lower tooth front side contact portion 21 and the lower tooth back side contact portion 22 are inclined in the same manner as the upper tooth front side contact portion 11 and the upper tooth back side contact portion 12, and accordingly, the lower tooth front side contact portion 21 and the lower tooth The distance from the back side contact portion 22 becomes narrower as the distance from the connecting plate portion 30 increases. The distance between the tip portions of both contact portions 21 and 22 is set to be shorter than the dimension in the front and back direction of the inserted molar 108a.

次に、上記のように構成された遺体用口開放防止具１の使用要領について説明する。まず、遺体用口開放防止具１を２つ用意する。そして、遺体の口１０３を開けて一方の遺体用口開放防止具１を口腔１００内に導入し、上顎１０１の左側の大臼歯１０７ａを上歯表側接触部１１及び上歯裏側接触部１２の間に差し込む。このとき差し込む大臼歯１０７ａは、図５に示すように、第１及び第２大臼歯１０７ａ、１０７ａが好ましい。   Next, how to use the corpse mouth opening prevention device 1 configured as described above will be described. First, two body opening prevention tools 1 are prepared. Then, the body's mouth 103 is opened, and one of the body's mouth opening prevention devices 1 is introduced into the oral cavity 100, and the left molars 107 a of the upper jaw 101 are placed between the upper tooth surface contact portion 11 and the upper tooth back contact portion 12. Plug in. The molars 107a to be inserted at this time are preferably first and second molars 107a and 107a as shown in FIG.

上歯表側接触部１１と上歯裏側接触部１２との先端部間の間隔が大臼歯１０７ａの表裏方向の寸法よりも狭いので、図６に示すように、大臼歯１０７ａを差し込むと両接触部１１，１２の間隔が広がっていき、大臼歯１０７ａの寸法及び形状に対応するように両接触部１１，１２が弾性変形する。やがて、大臼歯１０７ａの歯冠が連結板部３０に接触し、これにより、大臼歯１０７ａが上歯表側接触部１１と上歯裏側接触部１２との間に完全に差し込まれた状態となる。このとき、上歯表側接触部１１と上歯裏側接触部１２を弾性変形させているので、その復元力により表側接触部１１は大臼歯１０７ａの表側に圧接し、裏側接触部１２は大臼歯１０７ａの裏側に圧接する。これにより、表側及び裏側接触部１１，１２によって大臼歯１０７ａを表裏方向に挟持して大臼歯１０７ａが表側及び裏側接触部１１，１２の間から抜け難くなり、上歯係合部１０が大臼歯１０７ａに係合した状態となる。   Since the distance between the tip portions of the upper tooth front contact portion 11 and the upper tooth back contact portion 12 is narrower than the size of the front and back directions of the molar 107a, as shown in FIG. 6, when the molar 107a is inserted, both contact portions are inserted. The space | interval of 11 and 12 spreads, and both the contact parts 11 and 12 elastically deform so that it may respond to the size and shape of the molar 107a. Eventually, the crown of the molar 107a comes into contact with the connecting plate portion 30, and thereby the molar 107a is completely inserted between the upper tooth surface side contact portion 11 and the upper tooth back side contact portion 12. At this time, since the upper tooth front side contact portion 11 and the upper tooth back side contact portion 12 are elastically deformed, the front side contact portion 11 is pressed against the front side of the molar 107a by the restoring force, and the back side contact portion 12 is in contact with the molar 107a. Press against the back of the. As a result, the molars 107a are sandwiched in the front and back direction by the front and back contact portions 11 and 12, and the molars 107a are difficult to come out between the front and back contact portions 11 and 12, and the upper tooth engaging portion 10 is fixed to the molars. It will be in the state engaged with 107a.

また、他方の遺体用口開放防止具１を口腔１００内に導入し、該遺体用口開放防止具１の上歯表側接触部１１及び上歯裏側接触部１２の間に上顎１０１の右側の大臼歯１０７ａ、１０７ａを上記と同様にして差し込む。   In addition, the other body opening preventive tool 1 is introduced into the oral cavity 100, and the right upper side of the upper jaw 101 is placed between the upper teeth surface contact portion 11 and the upper teeth back contact portion 12 of the body opening preventive device 1. The molars 107a and 107a are inserted in the same manner as described above.

しかる後、下顎１０２を上顎１０１に接近させていき、左側の遺体用口開放防止具１の下歯表側接触部２１と下歯裏側接触部２２との間に、下顎１０２の左側の大臼歯１０８ａ，１０８ａを差し込む。この大臼歯１０８ａは、上顎１０１の大臼歯１０７ａと同じ第１及び第２大臼歯１０８ａ，１０８ａである。すると、下歯表側接触部２１と下歯裏側接触部２２は、上記した上歯表側接触部１１及び上歯裏側接触部１２と同様に弾性変形して大臼歯１０８ａが完全に差し込まれた状態となる。このとき、接触部２１，２２の復元力により表側接触部２１は大臼歯１０８ａの表側に圧接し、裏側接触部２２は大臼歯１０８ａの裏側に圧接するので、下歯係合部２０が大臼歯１０８ａ，１０８ａに係合した状態となる。   Thereafter, the lower jaw 102 is moved closer to the upper jaw 101, and the left molar tooth 108 a of the lower jaw 102 is placed between the lower teeth front side contact portion 21 and the lower teeth back side contact portion 22 of the left body opening prevention tool 1. 108a are inserted. The molars 108a are first and second molars 108a and 108a which are the same as the molars 107a of the upper jaw 101. Then, the lower tooth front side contact portion 21 and the lower tooth back side contact portion 22 are elastically deformed in the same manner as the upper tooth front side contact portion 11 and the upper tooth back side contact portion 12 described above, and the molar 108a is completely inserted. Become. At this time, the front side contact portion 21 is pressed against the front side of the molar 108a by the restoring force of the contact portions 21 and 22, and the back side contact portion 22 is pressed against the back side of the molar 108a. It will be in the state engaged with 108a and 108a.

また、他方の遺体用口開放防止具１の下歯表側接触部２１及び下歯裏側接触部２２の間に下顎１０２の右側の大臼歯１０８ａ，１０８ａを同様にして差し込む。   Also, the right molars 108a, 108a of the lower jaw 102 are inserted in the same manner between the lower tooth front side contact portion 21 and the lower tooth back side contact portion 22 of the other body opening prevention tool 1 for the corpse.

これにより、上顎１０１と下顎１０２とが接近した状態で保持されて口１０３が閉じられる。   As a result, the upper jaw 101 and the lower jaw 102 are held close to each other and the mouth 103 is closed.

尚、遺体用口開放防止具１の使用要領は上記に限られるものではなく、下歯係合部２０に下顎１０２の大臼歯１０８ａを係合させた後、上歯係合部１０に上顎１０１の大臼歯１０７ａを係合させるようにしてもよい。   The usage of the corpse mouth opening prevention device 1 is not limited to the above. After the lower teeth engaging portion 20 is engaged with the molar teeth 108a of the lower jaw 102, the upper teeth engaging portion 10 is engaged with the upper jaw 101. The molars 107a may be engaged.

以上説明したように、この実施形態１に係る遺体用口開放防止具１によれば、口腔１００内に導入した状態で、上歯係合部１０を上顎１０１の大臼歯１０７ａ，１０７ａに係合させ、下歯係合部２０を下顎１０２の大臼歯１０８ａ，１０８ａに係合させることにより、上顎１０１と下顎１０２とを接近させた状態で保持するようにしたので、納棺時及び葬儀の際に遺体用口開放防止具１を取り外す必要はなく、口１０３を確実に閉じさせておくことができる。   As described above, according to the corpse mouth opening prevention device 1 according to the first embodiment, the upper tooth engaging portion 10 is engaged with the molar teeth 107 a and 107 a of the upper jaw 101 in a state of being introduced into the oral cavity 100. Since the lower teeth engaging portion 20 is engaged with the molars 108a, 108a of the lower jaw 102, the upper jaw 101 and the lower jaw 102 are held close to each other. It is not necessary to remove the corpse mouth opening prevention tool 1, and the mouth 103 can be securely closed.

また、遺体用口開放防止具１を使用する際には、上顎１０１の大臼歯１０７ａ，１０７ａを上歯表側接触部１１と上歯裏側接触部１２との間に差し込み、下顎１０２の大臼歯１０８ａ，１０８ａを下歯表側接触部２１と下歯裏側接触部２２との間に差し込むという、簡単な作業を行うだけで済むので、作業性を良好にすることができる。   Further, when using the corpse mouth opening prevention device 1, the molars 107 a and 107 a of the upper jaw 101 are inserted between the upper tooth surface side contact portion 11 and the upper tooth back side contact portion 12, and the molar tooth 108 a of the lower jaw 102. , 108a is inserted between the lower tooth front side contact portion 21 and the lower tooth back side contact portion 22, so that it is only necessary to perform a simple work, so that workability can be improved.

また、上歯表側接触部１１及び上歯裏側接触部１２が互いに接離する方向に弾性変形するので、これら接触部１１，１２の間隔が、両接触部１１，１２の間に差し込んだ大臼歯１０７ａの寸法及び形状に対応するようになり、両接触部１１，１２が大臼歯１０７ａの表側及び裏側に確実に接触して大臼歯１０７ａをしっかりと挟持することができる。下歯係合部２０も同様に大臼歯１０８ａをしっかりと挟持することができる。   Further, since the upper tooth front side contact portion 11 and the upper tooth back side contact portion 12 are elastically deformed in the direction in which they come into contact with each other, the spacing between the contact portions 11 and 12 is a molar tooth inserted between the contact portions 11 and 12. It corresponds to the size and shape of 107a, and both contact portions 11 and 12 can securely contact the front side and the back side of the molar 107a, thereby firmly holding the molar 107a. Similarly, the lower teeth engaging portion 20 can firmly hold the molars 108a.

また、上歯表側接触部１１及び上歯裏側接触部１２に突条部１１ａ，１２ａを形成したので、突条部１１ａ，１２ａが大臼歯１０７ａの表側及び裏側の根に近い部分に引っ掛かるようになり、大臼歯１０７ａに対する滑り止めとして機能し、接触部１１，１２の間から大臼歯１０７ａが抜け難くなる。また、突条部２１ａ，２２ａも大臼歯１０８ａに対する滑り止めとして機能し、接触部２１，２２の間から大臼歯１０８ａが抜け難くなる。よって、口１０３が不意に開放してしまうのを未然に防止できる。   In addition, since the protrusions 11a and 12a are formed on the upper tooth front contact portion 11 and the upper tooth back contact portion 12, the protrusions 11a and 12a are hooked on portions near the front and back roots of the molars 107a. Thus, it functions as a slip stopper for the molar 107a, and the molar 107a is difficult to come out between the contact portions 11 and 12. Further, the ridges 21a and 22a also function as slip stoppers with respect to the molars 108a, and the molars 108a are difficult to come out between the contact parts 21 and 22. Therefore, it is possible to prevent the mouth 103 from opening unexpectedly.

また、上歯係合部１０が上顎１０１の複数の大臼歯１０７ａ，１０７ａに係合することになるので、上歯係合部１０が大臼歯１０７ａ，１０７ａから離脱し難くなる。また、下歯係合部２０も同様に下顎１０２の大臼歯１０８ａ，１０８ａから離脱し難くなる。このことによっても、口１０３が不意に開放してしまうのを未然に防止できる。   Further, since the upper tooth engaging portion 10 is engaged with the plurality of molar teeth 107a and 107a of the upper jaw 101, the upper tooth engaging portion 10 is difficult to be detached from the molar teeth 107a and 107a. Similarly, the lower tooth engaging portion 20 is difficult to be detached from the molar teeth 108a, 108a of the lower jaw 102. This also prevents the mouth 103 from opening unexpectedly.

また、遺体用口開放防止具１を、口腔１００の奥側にある大臼歯１０７ａ，１０８ａに係合させるようにしたので、例えば上唇と下唇との間に多少隙間があっても遺体用口開放防止具１が見えにくい。   Further, since the body opening prevention tool 1 is engaged with the molars 107a and 108a on the back side of the oral cavity 100, for example, even if there is a slight gap between the upper lip and the lower lip, The opening prevention tool 1 is difficult to see.

尚、上記実施形態１では、遺体用口開放防止具１を大臼歯１０７ａ、１０８ａに係合させるようにしているが、これに限らず、例えば、図８に示すように、切歯１０７ｂ、１０８ｂに係合させるようにしてもよい。遺体用口開放防止具１は、大臼歯１０７ａ，１０８ａ及び切歯１０７ｂ，１０８ｂ以外にも、犬歯１０７ｃ，１０８ｃや小臼歯１０７ｄ，１０８ｄに係合させるようにしてもよいし、大臼歯１０７ａ，１０８ａと小臼歯１０７ｄ，１０８ｄに係合させてもよいし、犬歯１０７ｃ，１０８ｃと切歯１０７ｂ、１０８ｂに係合させるようにしてもよく、係合させる歯１０７，１０８の組み合わせは自由に設定することができる。遺体用口開放防止具１の各部の寸法は、係合させる歯１０７，１０８の種類や、遺体の性別、体格、年齢、歯１０７，１０８の存在数等に応じて変更することが可能である。   In the first embodiment, the corpse mouth opening prevention device 1 is engaged with the molar teeth 107a and 108a. However, the present invention is not limited to this. For example, as shown in FIG. 8, the incisors 107b and 108b You may make it engage with.
