Description

本発明は、遺体の体液漏出防止剤注入用挿入管及び閉塞部材に関し、さらに詳しくは、体液漏出防止剤を遺体の体腔、特に口、鼻、耳などの体腔に装填して封止することにより、遺体からの体液漏出を防止するために、体液漏出防止剤用注入器の先端部に接続して用いられる遺体の体液漏出防止剤注入用挿入管及びその先端部に脱着自在に装着される閉塞部材に関する。   The present invention relates to an insertion tube for injecting a bodily fluid leakage preventive agent and an occlusion member, and more particularly, by loading and sealing a bodily fluid leakage preventing agent into a body cavity of a corpse, particularly a body cavity such as the mouth, nose, ear, and the like. In order to prevent leakage of bodily fluid from the corpse, an insertion tube for injecting the corporal fluid leakage preventive agent used by connecting to the distal end portion of the bodily fluid leakage preventing agent injector, and a closure that is detachably attached to the distal end portion It relates to members.

一般に、ヒトや動物の死亡後には体腔各部の筋肉が弛緩し、胃液、肺液、腹水、排泄物などの体液が漏出することが多く、悪臭や、病原菌による感染の原因ともなっている。このため、例えば病院では、死亡確認後、遺体の口、鼻、耳、肛門、女性の膣等の体腔に多量のガーゼ、脱脂綿等を装填し、体液の漏出を防ぐことが行なわれており、また、事故や手術後の遺体の開口部にも同様な処置がとられている。しかしながら、体腔へのガーゼ、脱脂綿等の装填作業の多くは、従業者や看護師等の手によって行われることが多く、その作業の煩雑さや不衛生さと同時に、ガーゼ、脱脂綿等は吸水能力が低いため、作業中もしくは作業後にしばしば体液が漏出してしまうという問題や、作業従事中にこの漏出物質による死後感染の可能性もあり、その解決が強く求められていた。   In general, after death of a human or animal, muscles in various parts of the body cavity are relaxed, and body fluids such as gastric fluid, lung fluid, ascites, and excreta are often leaked, causing malodor and infection by pathogenic bacteria. For this reason, for example, in hospitals, after confirming death, a large amount of gauze, absorbent cotton, etc. are loaded into body cavities such as the mouth, nose, ears, anus, and female vagina to prevent leakage of bodily fluids. Similar measures are also taken for the opening of the body after an accident or surgery. However, many of the operations for loading gauze, absorbent cotton, etc. into the body cavity are often performed by the hands of employees and nurses, etc., and at the same time the gauze, absorbent cotton, etc. have low water absorption capacity Therefore, there is a problem that body fluid often leaks during or after work, and there is a possibility of post-mortem infection due to this leaked substance during work, and there has been a strong demand for a solution.

このようなことから、ガーゼ、脱脂綿等に代えてゼリー状の体液漏出防止剤を口、鼻、耳、咽喉などに注入することが知られており、例えば、消臭剤入りの粉末ポリマーを適当量の水で溶かし適当に混合してゼリー状にしたものを用いる方法(特許文献1:特開平8−133901号公報参照)や、ジメチルアクリルアミドを主成分とする両親媒性ゲルを用いる方法(特許文献2:特開2001−288002号公報参照)、高吸水性ポリマー粉体を多数分散させたゼリー状体液漏出防止剤を用いる方法(特許文献3:特許第3586207号公報、特許文献4:特許第4029106号公報、特許文献5:特許第4081498号公報参照)が知られている。   For this reason, it is known to inject a jelly-like body fluid leakage prevention agent into the mouth, nose, ears, throat, etc. instead of gauze, absorbent cotton, etc. For example, a powder polymer containing a deodorant is suitable. A method using a jelly-like solution dissolved in an appropriate amount of water (see Patent Document 1: JP-A-8-133901), or a method using an amphiphilic gel containing dimethylacrylamide as a main component (patent Document 2: Japanese Patent Laid-Open No. 2001-288002), a method using a jelly-like body fluid leakage preventing agent in which a large number of superabsorbent polymer powders are dispersed (Patent Document 3: Patent No. 3586207, Patent Document 4: Patent No. 4) No. 4029106 and Patent Document 5: Japanese Patent No. 4081498) are known.

このようなゼリー状の体液漏出防止剤を、例えば鼻孔奥の咽喉部に充填する場合の充填方法について図1を参照しながら説明すると、特許文献4や特許文献5に記載のように、鼻孔や口等から挿入して咽喉部に前記体液漏出防止剤を注入・装填するための処置装置は、鼻孔等に挿入するための挿入管10と、ゼリー状の体液漏出防止剤Xが収容されている注入器20とからなる。注入器20は、先端に吐出筒部22を有する筒状本体21と、該筒状本体21内にその後端部から摺動自在に挿入されているピストン24とから構成されており、体液漏出防止剤Xは筒状本体21内に収容されている。なお、符号23は、筒状本体21の後端部に形成された指を引っ掛けるための半径方向外側に突出した一対の鍔部である。一方、挿入管10は、一端に注入器20先端の吐出筒部22に接続される接続部11を有し、先端に鼻孔等に挿入される開口部12を有する。挿入管10と注入器20の接続は、注入器20の先端部の吐出筒部22を挿入管10の後端の接続部11に嵌挿することにより行われる。符合13は、挿入管10の接続部もしくはその近傍に形成された環状のストッパ部である。   A filling method for filling such a jelly-like body fluid leakage preventing agent in the throat of the nostril, for example, will be described with reference to FIG. 1, as described in Patent Document 4 and Patent Document 5, A treatment device for injecting and loading the body fluid leakage preventing agent into the throat by inserting from the mouth or the like contains an insertion tube 10 for insertion into a nostril or the like, and a jelly-like body fluid leakage preventing agent X. And an injector 20. The injector 20 includes a cylindrical main body 21 having a discharge cylindrical portion 22 at the tip, and a piston 24 that is slidably inserted into the cylindrical main body 21 from the rear end thereof to prevent leakage of body fluid. The agent X is accommodated in the cylindrical main body 21. In addition, the code | symbol 23 is a pair of collar part which protruded in the radial direction outer side for hooking the finger formed in the rear-end part of the cylindrical main body 21. As shown in FIG. On the other hand, the insertion tube 10 has a connection part 11 connected to the discharge cylinder part 22 at the tip of the injector 20 at one end and an opening part 12 inserted into a nostril or the like at the tip. The connection between the insertion tube 10 and the injector 20 is performed by fitting the discharge cylinder portion 22 at the tip of the injector 20 into the connection portion 11 at the rear end of the insertion tube 10. Reference numeral 13 is an annular stopper formed at or near the connecting portion of the insertion tube 10.

次に、このようにして用意された遺体処置装置を使用する方法を説明する。図1において、Aは鼻孔、Bは咽喉部、Cは舌、Dは気管、Eは食道である。使用時には、フイルムパックから注入器20を取り出し、注入器20先端の吐出筒部22の保護キャップ(図示せず)を取り外し、挿入管10の接続部11を吐出筒部22に嵌め合わせて挿入管10を接続する。次いで、挿入管10の先端開口部12を鼻孔Aから咽喉部Bに向けて挿入し、挿入管10のストッパ部13が鼻先に当たった時点で挿入を停止する。そして、注入器20のピストン24を押圧し、注入器20内のゼリー状体液漏出防止剤Xを挿入管10を経由して咽喉部Bに注入する。注入器20内の体液漏出防止剤Xを押出し、充填した後は、注入器20と挿入管10を鼻孔Aから取り除く。   Next, a method for using the corpse treatment apparatus prepared in this way will be described. In FIG. 1, A is a nostril, B is a throat part, C is a tongue, D is a trachea, E is an esophagus. In use, the injector 20 is taken out from the film pack, the protective cap (not shown) of the discharge cylinder portion 22 at the tip of the injector 20 is removed, and the connection portion 11 of the insertion tube 10 is fitted to the discharge tube portion 22 to be inserted into the insertion tube. 10 is connected. Next, the distal end opening 12 of the insertion tube 10 is inserted from the nostril A toward the throat B, and the insertion is stopped when the stopper 13 of the insertion tube 10 hits the nose tip. Then, the piston 24 of the injector 20 is pressed, and the jelly-like body fluid leakage preventing agent X in the injector 20 is injected into the throat B through the insertion tube 10. After the body fluid leakage preventing agent X in the injector 20 is extruded and filled, the injector 20 and the insertion tube 10 are removed from the nostril A.

前記したようなゼリー状の体液漏出防止剤は、押し出し流動性が高く、鼻孔、耳穴等の狭い体腔であっても充填され易く、注入器で圧入しても飛散することがないという利点を有する。特に、高吸水性ポリマー粉体を多数分散させたゼリー状の体液漏出防止剤の場合、吸水性能が高く、このポリマーが体腔から漏出する体液を吸収し、外部へ漏出することを防止することが可能となる。
しかしながら、従来の注入器と挿入管の組合せの場合、遺体の体腔内に挿入管を挿入する際、挿入途中で挿入管の先端開口部が塞がれて体液漏出防止剤を注入し難くなるという問題や、先端部が体壁に引っ掛かって挿入し難くなるという問題がある。また、挿入管の開口部は比較的小さいため、体液漏出防止剤をスムーズに注入し難く、短時間の処理で充分な量の体液漏出防止を注入するという観点において未だ充分に満足しえるものではなかった。

The jelly-like body fluid leakage preventing agent as described above has a high extruding fluidity, and is easily filled even in a narrow body cavity such as a nostril or an ear hole, and has the advantage that it does not scatter even if it is press-fitted with an injector. . In particular, in the case of a jelly-like body fluid leakage preventing agent in which a large number of highly water-absorbing polymer powders are dispersed, the water absorption performance is high, and this polymer absorbs body fluid that leaks from the body cavity and prevents it from leaking outside. It becomes possible.
However, in the case of a combination of a conventional injector and an insertion tube, when the insertion tube is inserted into the body cavity of the corpse, the distal end opening of the insertion tube is blocked during the insertion, making it difficult to inject the body fluid leakage preventing agent. There is a problem and a problem that the tip part is caught on the body wall and is difficult to insert. In addition, since the opening of the insertion tube is relatively small, it is difficult to smoothly inject the body fluid leakage preventing agent, and it is still not fully satisfactory from the viewpoint of injecting a sufficient amount of body fluid leakage prevention with a short processing time. There wasn't.

従って、本発明の目的は、遺体の体腔内に挿入管を挿入する際、挿入途中で挿入管の先端開口部が塞がれて体液漏出防止剤を注入し難くなるという問題や、先端部が体壁に引っ掛かって挿入し難くなるという問題もなく、遺体の口、鼻、耳などの体腔に熟練を要することなく簡単に挿入できる操作性に優れ、また体液漏出防止剤をスムーズに注入でき、比較的短時間の処理で充分な量の体液漏出防止を注入できる遺体の体液漏出防止剤注入用挿入管を提供することにある。
さらに本発明の目的は、体液漏出防止剤注入用挿入管の先端開口部への着脱性に優れると共に、遺体の体腔内への挿入管の挿入性にも優れ、体液漏出防止剤注入用挿入管の先端開口部を閉塞するのに好適に用いることができる閉塞部材を提供することにある。
Therefore, the object of the present invention is that when the insertion tube is inserted into the body cavity of the corpse, the distal end of the insertion tube is blocked during the insertion, making it difficult to inject the body fluid leakage preventing agent. There is no problem that it becomes difficult to insert by being caught on the body wall, it is excellent in operability that can be easily inserted into the body cavity such as the mouth, nose, ear etc. of the corpse without requiring skill, and the fluid leakage preventing agent can be injected smoothly, An object of the present invention is to provide an insertion tube for injecting a bodily fluid leakage preventive agent capable of injecting a sufficient amount of bodily fluid leakage prevention with a relatively short processing time.
Furthermore, the object of the present invention is excellent in detachability to the distal end opening of an insertion tube for injecting a body fluid leakage prevention agent, and also excellent in insertability of the insertion tube into a body cavity of a corpse, and an insertion tube for injecting a body fluid leakage prevention agent It is in providing the obstruction | occlusion member which can be used suitably for obstruct | occluding the front-end | tip opening part.

前記目的を達成するために、本発明によれば、体液漏出防止剤を遺体の体腔内に注入するために用いられる合成樹脂製挿入管であって、その先端部に、先端から所定距離だけ軸線方向に複数の線状切断部が形成されていると共に、該線状切断部に沿って延在する筒状部を有する先端部外形が略半球状の閉塞部材が脱着自在に装着されており、且つ、上記閉塞部材又は挿入管先端近傍部に空気抜け部が形成されていることを特徴とする遺体の体液漏出防止剤注入用挿入管が提供される。
ここで、線状切断部は、挿入管の先端開口部近傍の環状周壁の連続性を切断する部分を意味し、好ましくは、先端から所定距離だけ軸線方向に形成された切れ目もしくはスリット又はこれらの組み合わせからなる。
In order to achieve the above object, according to the present invention, there is provided a synthetic resin insertion tube used for injecting a bodily fluid leakage prevention agent into a body cavity of a corpse. A plurality of linear cutting parts are formed in the direction, and a closing member having a cylindrical part extending along the linear cutting parts and having a substantially hemispherical outer shape is detachably mounted. In addition, an insertion tube for injecting a body fluid leakage preventing agent is provided, wherein an air escape portion is formed in the vicinity of the closing member or the distal end of the insertion tube.
Here, the linear cutting portion means a portion that cuts the continuity of the annular peripheral wall in the vicinity of the distal end opening of the insertion tube, and preferably, a cut or slit formed in the axial direction by a predetermined distance from the distal end or these Composed of a combination.

さらに本発明によれば、体液漏出防止剤を遺体の体腔内に注入するために用いられる合成樹脂製挿入管の先端部に脱着自在に装着されるのに特に好適な閉塞部材も提供される。即ち、装着される挿入管の先端部外径と略等しい直径を有し、先端部外形が略半球状の頭部と、挿入管の先端部内径よりも僅かに小さな外径の筒状部とからなり、該筒状部の外周面に軸線方向に複数本の突条が形成されていることを特徴とする閉塞部材も提供される。   Furthermore, according to the present invention, there is also provided an occlusion member that is particularly suitable for being detachably attached to a distal end portion of a synthetic resin insertion tube used for injecting a body fluid leakage preventing agent into a body cavity of a corpse. That is, a head having a diameter approximately equal to the outer diameter of the distal end of the insertion tube to be mounted and having a substantially hemispherical tip outer shape, and a cylindrical portion having an outer diameter slightly smaller than the inner diameter of the distal end of the insertion tube, There is also provided a closing member characterized in that a plurality of protrusions are formed in the axial direction on the outer peripheral surface of the cylindrical portion.

本発明に係る遺体の体液漏出防止剤注入用挿入管は、その先端部に、先端から所定距離だけ軸線方向に複数の線状切断部が形成されていると共に、閉塞部材の筒状部が挿入管の先端部に形成された複数の線状切断部に沿って延在するように、好ましくは該線状切断部を覆うように、先端部外形が略半球状の閉塞部材が脱着自在に装着されている。そのため、先端開口部が体壁に引っ掛かって挿入し難くなるという問題を回避でき、遺体の体腔内にスムーズに挿入できると共に、咽頭部等の目的部位に到達するまでは体液漏出防止剤が体液に触れることがない。挿入管の先端部が目的部位に達したときにピストンを押すと、まず最初に挿入管内の空気が閉塞部材又は挿入管先端近傍部に形成された空気抜け部を通して挿入管内から押し出され、次いでピストンにより先端部まで押し出された体液漏出防止剤の押圧力によって、閉塞部材は挿入管の先端部から簡単に外れる。それと同時に、ピストンにより押し出される体液漏出防止剤の押圧力は環状周壁部にも作用するので、複数の線状切断部間に形成される舌片が側方に押されてラッパ状に拡開し、体腔内を押し広げるように作用する。そのため、挿入途中で挿入管の先端開口部が塞がれて体液漏出防止剤を注入し難くなるという問題を回避できると共に、スムーズに体液漏出防止剤を注入・装填することができ、比較的短時間の処理で充分な量の体液漏出防止を注入できる。また、体液漏出防止剤を遺体の体腔内に注入する際に同時に閉塞部材が体腔内に押し出され、遺体の体内に残っても、対象物が遺体のため、生体の場合のような拒絶反応やアレルギー反応はなんら問題となることはなく、無害である。   In the insertion tube for injecting a body fluid leakage preventing agent according to the present invention, a plurality of linear cutting portions are formed in the axial direction at a predetermined distance from the distal end, and the cylindrical portion of the closing member is inserted A closing member having a substantially hemispherical outer shape is attached to the tube so as to extend along a plurality of linear cutting portions formed at the tip of the tube, preferably covering the linear cutting portions. Has been. Therefore, it is possible to avoid the problem that the tip opening is caught by the body wall and is difficult to insert, and can be smoothly inserted into the body cavity of the corpse, and the body fluid leakage preventive agent is added to the body fluid until reaching the target site such as the pharynx. There is no touch. When the piston is pushed when the distal end of the insertion tube reaches the target site, the air in the insertion tube is first pushed out of the insertion tube through the air blocking part formed in the blocking member or the vicinity of the distal end of the insertion tube. The blocking member is easily detached from the distal end portion of the insertion tube by the pressing force of the bodily fluid leakage preventing agent pushed out to the distal end portion. At the same time, the pressing force of the body fluid leakage preventing agent pushed out by the piston also acts on the annular peripheral wall portion, so that the tongue piece formed between the plurality of linear cutting portions is pushed sideways and expands in a trumpet shape. It acts to spread the body cavity. Therefore, it is possible to avoid the problem that the distal end opening of the insertion tube is blocked during insertion and it is difficult to inject the body fluid leakage preventing agent, and it is possible to smoothly inject and load the body fluid leakage preventing agent. A sufficient amount of bodily fluid leakage prevention can be injected with the treatment of time. In addition, when the body fluid leakage preventing agent is injected into the body cavity of the corpse, the blocking member is pushed into the body cavity at the same time. Allergic reactions do not cause any problems and are harmless.

さらに本発明の体液漏出防止剤注入用挿入管の先端部に装着されるのに特に好適な閉塞部材は、装着される挿入管の先端部外径と略等しい直径を有し、先端部外形が略半球状の頭部と、挿入管の先端部内径よりも僅かに小さな外径の筒状部とからなり、該筒状部の外周面に軸線方向に複数本の突条が形成されているため、閉塞部材の筒状部と挿入管先端部の内周面との間の摩擦力が軽減し、挿入管の先端開口部への着脱性に優れていると共に、筒状部の外周面と挿入管先端部の内周面との間に形成される空隙部(ギャップ)は空気抜け部として機能する。また、閉塞部材の頭部と挿入管の先端部の外径がほぼ等しいため、遺体の体腔内への挿入管の挿入性にも優れている。さらに、一旦挿入管を鼻腔に挿入した際に、後鼻孔の蝶篩陥凹等の窪みに挟まり、再度挿入操作をやり直そうとした時に、閉塞部材の頭部が挿入管の先端部外径よりも大きい場合には取り出す際に閉塞部材が抜け出ることがあるが、本発明の上記閉塞部材の場合、閉塞部材の頭部と挿入管の先端部の外径がほぼ等しいため、このような問題もなく、挿入操作を容易にやり直しすることができる。従って、前記した先端部に切れ目やスリット等の線状切断部が形成されている挿入管に好適に用いることができるだけでなく、このような線状切断部が形成されていない他の体液漏出防止剤注入用挿入管、例えば先端から所定距離の範囲の周壁に1個以上の体液漏出防止剤注入用の側孔が形成されて充分な注入用開口面積が形成された挿入管の先端開口部を閉塞するのにも好適に用いることができる。   Further, the occlusion member particularly suitable for being attached to the distal end portion of the insertion tube for injecting the body fluid leakage preventing agent of the present invention has a diameter substantially equal to the outer diameter of the distal end portion of the inserted insertion tube, and the outer shape of the distal end portion is It consists of a substantially hemispherical head and a cylindrical portion having an outer diameter slightly smaller than the inner diameter of the distal end portion of the insertion tube, and a plurality of protrusions are formed in the axial direction on the outer peripheral surface of the cylindrical portion. Therefore, the frictional force between the cylindrical portion of the blocking member and the inner peripheral surface of the insertion tube distal end is reduced, and the attachment and detachment to the distal end opening of the insertion tube is excellent, and the outer peripheral surface of the cylindrical portion A gap portion (gap) formed between the inner peripheral surface of the distal end portion of the insertion tube functions as an air escape portion. In addition, since the outer diameters of the head portion of the blocking member and the distal end portion of the insertion tube are substantially equal, the insertion property of the insertion tube into the body cavity of the body is also excellent. Furthermore, when the insertion tube is once inserted into the nasal cavity, it is pinched in a recess such as a butterfly sieve recess in the rear nostril, and when the insertion operation is attempted again, the head of the blocking member is larger than the outer diameter of the distal end portion of the insertion tube. If it is larger, the closing member may come out when it is taken out. However, in the case of the closing member of the present invention, the outer diameters of the head of the closing member and the distal end of the insertion tube are almost equal, so there is no such problem. The insertion operation can be easily redone. Therefore, it can be suitably used for an insertion tube in which a linear cutting part such as a cut line or a slit is formed at the above-mentioned distal end part, as well as other body fluid leakage prevention in which such a linear cutting part is not formed. For example, a distal end portion of an insertion tube in which one or more side holes for injecting a body fluid leakage preventing agent are formed on a peripheral wall within a predetermined distance from the distal end to form a sufficient opening area for injection. It can also be suitably used for blocking.

後端部が体液漏出防止剤用注入器の先端の吐出筒部に接続され、先端から遺体の体腔内に挿入されて上記注入器内の体液漏出防止剤を遺体の体腔内に注入するために用いられる合成樹脂製挿入管において、遺体の体腔内に挿入管を挿入する際、挿入途中で挿入管の先端開口部が塞がれて体液漏出防止剤を注入し難くなるという問題や、先端部が体壁に引っ掛かって挿入し難くなるという問題を回避し、簡単に挿入できるようにするためには、挿入管の先端部を丸くすればよいと考えられる。しかしながら、挿入管自体の先端部を丸くすれば、先端開口部の孔径は小さくなってしまい、体液漏出防止剤の注入が困難になる。そこで、挿入管とは別体の閉塞部材を用い、その先端部外形を略半球状(丸みを帯びた形状)にし、これを、体液漏出防止剤を遺体の体腔内に注入する際に同時に体腔内に押し出されるような係合力で挿入管の先端部に脱着自在に装着すれば、体液漏出防止剤の注入を阻害することなく、挿入途中で挿入管の先端開口部が塞がれて体液漏出防止剤を注入し難くなるという問題や、先端部が体壁に引っ掛かって挿入し難くなるという問題を回避できる。   The rear end is connected to the discharge cylinder at the tip of the body fluid leakage preventive injector, and is inserted into the body cavity of the corpse from the tip to inject the fluid leakage preventive agent in the body into the body cavity of the body. In the synthetic resin insertion tube used, when the insertion tube is inserted into the body cavity of the corpse, there is a problem that the distal end opening of the insertion tube is blocked during the insertion, making it difficult to inject the body fluid leakage preventing agent, In order to avoid the problem of being difficult to insert due to being caught on the body wall and to enable easy insertion, it is considered that the distal end of the insertion tube should be rounded. However, if the distal end portion of the insertion tube itself is rounded, the hole diameter of the distal end opening portion becomes smaller, and it becomes difficult to inject the body fluid leakage preventing agent. Therefore, an occlusion member separate from the insertion tube is used, and the outer shape of the tip is made into a substantially hemispherical shape (rounded shape), which is simultaneously injected into the body cavity of the body fluid leakage prevention agent. If it is detachably attached to the distal end of the insertion tube with an engaging force that pushes it into the body, the distal end of the insertion tube is blocked during insertion without blocking the injection of the body fluid leakage preventing agent. It is possible to avoid the problem that it becomes difficult to inject the inhibitor and the problem that it becomes difficult to insert the tip part by being caught on the body wall.

また、ピストンにより押し出される体液漏出防止剤の押圧力は、前進方向(軸線方向)と半径方向に作用するが、閉塞部材の筒状部が挿入管の先端部に形成された複数の線状切断部に沿って延在しているため、好ましくは挿入管の先端部に形成された複数の線状切断部は閉塞部材によって覆われているため、閉塞部材が先端部から外れない限り、複数の線状切断部間に形成される舌片が側方に押されてラッパ状に拡開することはない。すなわち、注入器内の体液漏出防止剤をピストンにより押し出すと、その前進方向(軸線方向)の押圧力により、まず最初に挿入管内の空気が閉塞部材又は挿入管先端近傍部に形成された空気抜け部を通して挿入管内から押し出され、次いでピストンにより先端部まで押し出された体液漏出防止剤の押圧力によって、閉塞部材が挿入管の先端部から外れる。閉塞部材が挿入管の先端部から外れると同時に、ピストンにより押し出される体液漏出防止剤の半径方向の押圧力は環状周壁部に作用し、複数の線状切断部間に形成される舌片が側方に押されてラッパ状に拡開し、体腔内を押し広げるように作用する。そのため、スムーズに体液漏出防止剤を注入・装填することができ、比較的短時間の処理で充分な量の体液漏出防止を注入できる。   Further, the pressing force of the body fluid leakage preventing agent pushed out by the piston acts in the forward direction (axial direction) and the radial direction, but a plurality of linear cuts in which the cylindrical portion of the blocking member is formed at the distal end portion of the insertion tube Since the plurality of linear cutting portions formed at the distal end portion of the insertion tube are preferably covered with the closing member, a plurality of linear cutting portions are formed as long as the closing member does not come off from the distal end portion. The tongue piece formed between the linear cut portions is not pushed sideways and spreads in a trumpet shape. That is, when the body fluid leakage preventing agent in the injector is pushed out by the piston, the air in the insertion tube is first formed in the vicinity of the closing member or the distal end of the insertion tube by the pressing force in the forward direction (axial direction). The blocking member is removed from the distal end portion of the insertion tube by the pressing force of the body fluid leakage preventing agent pushed out from the insertion tube through the portion and then pushed out to the distal end portion by the piston. At the same time that the blocking member is disengaged from the distal end portion of the insertion tube, the radial pressing force of the body fluid leakage preventing agent pushed out by the piston acts on the annular peripheral wall portion, and the tongue piece formed between the plurality of linear cutting portions is on the side. When pressed in the direction, it expands in a trumpet shape and acts to push the inside of the body cavity. Therefore, the bodily fluid leakage prevention agent can be injected and loaded smoothly, and a sufficient amount of bodily fluid leakage prevention can be injected in a relatively short time.

体液漏出防止剤注入用挿入管の先端部に脱着自在に装着される閉塞部材としては、先端部外形が略半球状の頭部(中空及び中実のいずれの半球状頭部でもよい)と、挿入管先端部に嵌め合わされる筒状部(中空及び中実のいずれの筒状部でもよい)を有する閉塞部材であれば全て用いることができるが、装着される挿入管の先端部外径と略等しい直径を有し、先端部外形が略半球状の頭部と、挿入管の先端部内径よりも僅かに小さな外径の筒状部とからなり、該筒状部の外周面に軸線方向に複数本の突条が形成されている閉塞部材が特に好ましい。このように筒状部の外周面に軸線方向に複数本の突条が形成されているため、閉塞部材の筒状部と挿入管先端部内周面との間の摩擦力が軽減し、挿入管の先端開口部への着脱性に優れている。また、閉塞部材の頭部と挿入管の先端部の外径がほぼ等しいため、遺体の体腔内への挿入管の挿入性にも優れており、また、一旦挿入管を鼻腔に挿入した際に、後鼻孔の蝶篩陥凹等の窪みに挟まり、再度挿入操作をやり直そうとした時に、閉塞部材の頭部が挿入管の先端部外径よりも大きい場合には取り出す際に閉塞部材が抜け出ることがあるが、閉塞部材の頭部と挿入管の先端部の外径がほぼ等しいため、このような問題もなく、挿入操作を容易にやり直しすることができる。   As a closing member that is detachably attached to the distal end portion of the insertion tube for injecting the body fluid leakage preventing agent, the outer shape of the distal end portion is a substantially hemispherical head (both hollow and solid hemispherical heads), Any occlusion member having a cylindrical part (both hollow and solid cylindrical parts) fitted to the distal end of the insertion tube can be used. Consists of a substantially hemispherical head having substantially the same diameter and a substantially hemispherical head, and a cylindrical portion having an outer diameter slightly smaller than the inner diameter of the distal end of the insertion tube. A closing member in which a plurality of protrusions are formed is particularly preferable. As described above, since a plurality of protrusions are formed in the axial direction on the outer peripheral surface of the cylindrical portion, the frictional force between the cylindrical portion of the closing member and the inner peripheral surface of the insertion tube tip portion is reduced, and the insertion tube Excellent detachability to the tip opening. In addition, since the outer diameter of the head of the blocking member and the distal end of the insertion tube are almost equal, the insertion tube can be easily inserted into the body cavity of the body, and once the insertion tube is inserted into the nasal cavity If the head of the blocking member is larger than the outer diameter of the distal end of the insertion tube when it is sandwiched in a recess such as a butterfly dent in the nostril of the rear nostril and the insertion operation is attempted again, the blocking member will come out when being removed. However, since the outer diameters of the head portion of the closing member and the distal end portion of the insertion tube are substantially equal, the insertion operation can be easily performed without such a problem.

以下、添付図面を参照しながら、本発明に係る挿入管及びそれを用いた好適な遺体の処置装置の各種態様の具体例について説明する。   Hereinafter, specific examples of various aspects of an insertion tube according to the present invention and a suitable corpse treatment apparatus using the same will be described with reference to the accompanying drawings.

図2は、本発明の挿入管の一実施態様の先端部を示している。挿入管1は、鼻孔や口に挿入した際、鼻腔形状や口蓋形状に沿って撓む柔軟性を有するポリエステルエラストマー、軟質塩化ビニル樹脂、ゴム等の可撓性の合成樹脂から作製されており、好ましくは透明又は半透明である。図2に示されるように、挿入管1の先端部には、先端から所定距離だけ軸線方向に複数の切れ目3が形成されている。尚、図示の実施態様の場合、切れ目3の数は4個であるが、2個以上の任意の複数個とすることができ、好ましくは3個以上、特に好ましくは4個以上のすることにより、体液漏出防止剤の半径方向の押圧力が作用した時に、切れ目3間に形成される舌片4が側方に押されてラッパ状に拡開し易くすることが好ましい。また、挿入管1の先端開口部2には、鼻孔や口から挿入し易いように、先端部外形が略半球状のドーム状の閉塞部材5が脱着自在に被冠されている。閉塞部材5は、合成樹脂製の中空の半球状頭部6と円筒状部7とからなり、円筒状部7の内径は挿入管1の先端部の外径と略同一である。円筒状部7の長さは上記切れ目3を少なくとも部分的に覆う長さとする必要があるが、好ましくは上記切れ目3全体を覆うような長さとする。また、閉塞部材5の半球状頭部6の先端部には、空気抜け部として機能する微細な空気孔8が形成されている。このような空気孔8を形成することにより、ピストンにより押し出される体液漏出防止剤の押圧力によって押された挿入管1内の空気は空気孔8を通して外部に排出されるので、体液漏出防止剤注入開始時に閉塞部材5が挿入管1の先端部から外れることを回避できる。尚、挿入管1の先端部に嵌め合わされる閉塞部材5の係合力は、体液漏出防止剤を遺体の体腔内に注入する際に同時に閉塞部材5が体腔内に押し出されるような係合力であればよい。   FIG. 2 shows the tip of one embodiment of the insertion tube of the present invention. The insertion tube 1 is made of a flexible synthetic resin such as a polyester elastomer, a soft vinyl chloride resin, or a rubber having flexibility to bend along a nasal cavity shape or a palate shape when inserted into a nostril or mouth. Preferably it is transparent or translucent. As shown in FIG. 2, a plurality of cuts 3 are formed at the distal end portion of the insertion tube 1 in the axial direction by a predetermined distance from the distal end. In the case of the illustrated embodiment, the number of the cuts 3 is four, but it can be any two or more, preferably three or more, particularly preferably four or more. When the pressing force in the radial direction of the bodily fluid leakage preventing agent is applied, it is preferable that the tongue piece 4 formed between the cuts 3 is pushed to the side so as to easily expand in a trumpet shape. In addition, the distal end opening 2 of the insertion tube 1 is detachably covered with a dome-shaped blocking member 5 having a substantially hemispherical distal end shape so that it can be easily inserted from a nostril or mouth. The blocking member 5 includes a hollow hemispherical head 6 made of synthetic resin and a cylindrical portion 7, and the inner diameter of the cylindrical portion 7 is substantially the same as the outer diameter of the distal end portion of the insertion tube 1. The length of the cylindrical portion 7 needs to be a length that at least partially covers the cut 3, but is preferably a length that covers the entire cut 3. A fine air hole 8 that functions as an air escape portion is formed at the tip of the hemispherical head 6 of the closing member 5. By forming such an air hole 8, the air in the insertion tube 1 pushed by the pressing force of the bodily fluid leakage preventing agent pushed out by the piston is discharged to the outside through the air hole 8, so that the bodily fluid leakage preventing agent injection It is possible to avoid the closing member 5 from being detached from the distal end portion of the insertion tube 1 at the start. The engaging force of the blocking member 5 fitted to the distal end portion of the insertion tube 1 should be such that the blocking member 5 is pushed into the body cavity at the same time when the body fluid leakage preventing agent is injected into the body cavity. That's fine.

一方、図3は、図2に示す挿入管の変形例を示している。この実施態様の場合、挿入管1の先端部に被冠される閉塞部材5aは、空気孔8を有する中実の半球状頭部6aと円筒状部7とからなる点において、前記実施態様と異なるが、他の構成は前記実施態様と同じである。   On the other hand, FIG. 3 shows a modification of the insertion tube shown in FIG. In the case of this embodiment, the blocking member 5a to be crowned at the distal end portion of the insertion tube 1 is composed of a solid hemispherical head 6a having an air hole 8 and a cylindrical portion 7 in the above embodiment. Although different, other configurations are the same as those of the above embodiment.

図4は、本発明の挿入管の他の実施態様の先端部を示している。この実施態様の挿入管1aの場合、前記図2に示す切れ目に代えて、挿入管1aの先端部には、先端から所定距離だけ軸線方向に複数のスリット3aが形成されている。尚、本実施態様の場合にも、スリット3aの数は4個であるが、2個以上の任意の複数個とすることができ、好ましくは3個以上、特に好ましくは4個以上のすることにより、体液漏出防止剤の半径方向の押圧力が作用した時に、スリット3a間に形成される舌片4が側方に押されてラッパ状に拡開し易くすることが好ましい。また、前記図2に示す実施態様と同様に、挿入管1の先端開口部2には、鼻孔や口から挿入し易いように、先端部外形が略半球状のドーム状の閉塞部材5が脱着自在に被冠されている。閉塞部材5の空気孔8を有する中空の半球状頭部6や円筒状部7の形状・寸法、挿入管1aの先端部に嵌め合わされる閉塞部材5の係合力等は、前記図2に示す実施態様と同様である。
尚、線状切断部として、前記図2に示す切れ目3と図4に示すスリット3aを組み合わせて形成してもよい。
FIG. 4 shows the tip of another embodiment of the insertion tube of the present invention. In the case of the insertion tube 1a of this embodiment, a plurality of slits 3a are formed in the axial direction by a predetermined distance from the distal end of the insertion tube 1a instead of the cut shown in FIG. In this embodiment as well, the number of slits 3a is four, but it can be two or more, preferably three or more, particularly preferably four or more. Thus, it is preferable that the tongue piece 4 formed between the slits 3a is pushed to the side and easily expands in a trumpet shape when a pressing force in the radial direction of the body fluid leakage preventing agent is applied. Similarly to the embodiment shown in FIG. 2, a dome-shaped blocking member 5 having a substantially hemispherical tip is attached to and removed from the tip opening 2 of the insertion tube 1 so that it can be easily inserted from a nostril or mouth. It is freely crowned. FIG. 2 shows the shape and dimensions of the hollow hemispherical head 6 and the cylindrical portion 7 having the air holes 8 of the closing member 5, the engagement force of the closing member 5 fitted to the distal end portion of the insertion tube 1a, and the like. This is the same as the embodiment.
Note that the cut line 3 shown in FIG. 2 and the slit 3a shown in FIG.

図5は、前記実施態様の閉塞部材の変形例を示している。この実施態様においては、閉塞部材5bは、挿入管1の外径とほぼ等しい直径を有する中実の半球状頭部6bと、挿入管1の先端部の内径と略同一の直径を有する丸棒部(中実の筒状部)9とが一体となったきのこ状の外形を有し、該閉塞部材5bの丸棒部9が挿入管1の先端開口部に脱着自在に嵌挿されている。この実施態様の閉塞部材5bにおいても、半球状頭部6bと丸棒部9に軸線方向に微細な空気孔8が形成されている。尚、この実施態様のように閉塞部材5bの丸棒部9が挿入管1の先端開口部に嵌挿される場合、閉塞部材5bが挿入管1の先端部から外れる前に複数の切れ目3(又はスリット3a)間に形成される舌片4が側方に押されてラッパ状に拡開するのを防止するために、丸棒部9の長さは切れ目3(又はスリット3a)の長さよりも長くすることが好ましい。この実施態様のように、閉塞部材5bの半球状頭部6bと挿入管1の先端部の外径がほぼ等しい場合、遺体の体腔内への挿入管の挿入性に優れていると共に、挿入操作のやり直し性にも優れている。   FIG. 5 shows a modification of the closing member of the embodiment. In this embodiment, the blocking member 5b includes a solid hemispherical head 6b having a diameter substantially equal to the outer diameter of the insertion tube 1 and a round bar having a diameter substantially the same as the inner diameter of the distal end portion of the insertion tube 1. And a round bar portion 9 of the closing member 5b is detachably inserted into the distal end opening of the insertion tube 1. . Also in the closing member 5b of this embodiment, fine air holes 8 are formed in the hemispherical head 6b and the round bar portion 9 in the axial direction. When the round bar portion 9 of the closing member 5b is fitted into the distal end opening of the insertion tube 1 as in this embodiment, a plurality of cuts 3 (or before the closing member 5b is detached from the distal end portion of the insertion tube 1). In order to prevent the tongue 4 formed between the slits 3a) from being pushed sideways and expanding in a trumpet shape, the length of the round bar portion 9 is larger than the length of the cut 3 (or the slit 3a). It is preferable to make it longer. When the outer diameters of the hemispherical head 6b of the closing member 5b and the distal end of the insertion tube 1 are substantially equal as in this embodiment, the insertion tube can be inserted into the body cavity of the corpse, and the insertion operation can be performed. It is also excellent in redoing.

尚、前記いずれの実施態様においても、空気孔8は、閉塞部材5,5a,5bの半球状頭部6,6a,6bのいずれの箇所に設けてもよく、また挿入管1,1aの先端近傍部(円筒状部7又は丸棒部9が延在する領域を外れた箇所)の周壁に設けてもよい。また、空気孔8の数は、1個以上の任意の数でよい。   In any of the above embodiments, the air hole 8 may be provided at any location of the hemispherical heads 6, 6a, 6b of the closing members 5, 5a, 5b, and the distal end of the insertion tube 1, 1a. You may provide in the surrounding wall of the vicinity part (location which remove | deviated the area | region where the cylindrical part 7 or the round bar part 9 extends). Further, the number of air holes 8 may be an arbitrary number of one or more.

前記挿入管1(1a)の使用に際しては、まず、前記図1に示すような注入器20の吐出筒部22の保護キャップ(図示せず)を取り外し、挿入管1(1a)の接続部に吐出筒部22を嵌め合わせて挿入管1(1a)と注入器20を接続する。次いで、挿入管1(1a)及びその先端に装着されている閉塞部材5(5a,5b)を鼻孔A(図1参照)又は口から咽喉部Bに向けて挿入し、ストッパ部13(又は注入器20の筒状本体21の先端部)が鼻先又は口元に位置した時点で挿入を停止する。この際、挿入抵抗を軽減するために、閉塞部材5(5a,5b)及び挿入管1の表面にグリセリン等の潤滑剤を塗布してもよい。また、より少ない押圧力で閉塞部材が外れるようにするために、挿入管への閉塞部材の装着前に、閉塞部材の挿入管との接触面又は挿入管の先端部に潤滑剤を塗布しておくこともできる。そして、注入器20のピストン24を押圧し、注入器20内の体液漏出防止剤Xを挿入管1(1a)を経由して咽喉部Bに注入する。   When using the insertion tube 1 (1a), first, a protective cap (not shown) of the discharge cylinder portion 22 of the injector 20 as shown in FIG. 1 is removed, and the connection portion of the insertion tube 1 (1a) is removed. The discharge tube portion 22 is fitted together to connect the insertion tube 1 (1a) and the injector 20. Next, the insertion tube 1 (1a) and the blocking member 5 (5a, 5b) attached to the distal end of the insertion tube 1 are inserted from the nostril A (see FIG. 1) or the mouth toward the throat B, and the stopper 13 (or injection) The insertion is stopped when the tip of the cylindrical body 21 of the container 20 is located at the tip of the nose or the mouth. At this time, in order to reduce the insertion resistance, a lubricant such as glycerin may be applied to the surfaces of the blocking member 5 (5a, 5b) and the insertion tube 1. In order to remove the blocking member with less pressing force, before attaching the blocking member to the insertion tube, apply a lubricant to the contact surface of the blocking member with the insertion tube or the tip of the insertion tube. It can also be left. Then, the piston 24 of the injector 20 is pressed, and the body fluid leakage preventing agent X in the injector 20 is injected into the throat B through the insertion tube 1 (1a).

このように注入器20内の体液漏出防止剤Xをピストン24により押し出すと、その前進方向(軸線方向)の押圧力により、まず最初に挿入管1(1a)内の空気が閉塞部材5(5a,5b)に形成された空気孔(8)を通して挿入管内から押し出され、次いでピストン24により先端部まで押し出された体液漏出防止剤Xの押圧力によって、閉塞部材5(5a,5b)が挿入管1(1a)の先端部から外れる。閉塞部材5(5a,5b)が挿入管1(1a)の先端部から外れると同時に、ピストン24により押し出される体液漏出防止剤Xの半径方向の押圧力は環状周壁部に作用し、複数の切れ目3(又はスリット3a)間に形成される舌片4が側方に押されてラッパ状に拡開し、体腔内を押し広げるように作用する。そのため、スムーズに体液漏出防止剤を注入・装填することができ、比較的短時間の処理で充分な量の体液漏出防止を注入できる。閉塞部材5(5a,5b)及び注入器20内の体液漏出防止剤Xを押出し、充填した後は、注入器20と挿入管1(1a)を鼻孔A又は口から抜き出す。   When the bodily fluid leakage preventing agent X in the injector 20 is pushed out by the piston 24 in this way, first, the air in the insertion tube 1 (1a) is first squeezed by the pushing force in the forward direction (axial direction). , 5b), the blocking member 5 (5a, 5b) is inserted into the insertion tube by the pressing force of the body fluid leakage preventing agent X pushed out from the insertion tube through the air hole (8) formed in the air hole (8) and then pushed out to the tip by the piston 24. 1 (1a) comes off the tip. At the same time that the blocking member 5 (5a, 5b) is disengaged from the distal end portion of the insertion tube 1 (1a), the radial pressing force of the bodily fluid leakage preventing agent X pushed out by the piston 24 acts on the annular peripheral wall portion, and a plurality of cuts 3 (or the slit 3a), the tongue piece 4 is pushed to the side to expand in a trumpet shape, and acts to push the inside of the body cavity. Therefore, the bodily fluid leakage prevention agent can be injected and loaded smoothly, and a sufficient amount of bodily fluid leakage prevention can be injected in a relatively short time. After extruding and filling the blocking member 5 (5a, 5b) and the body fluid leakage preventing agent X in the injector 20, the injector 20 and the insertion tube 1 (1a) are extracted from the nostril A or the mouth.

図6及び図7は、本発明の閉塞部材の好適な実施態様を示している。この実施態様においては、閉塞部材5cは、挿入管1の外径とほぼ等しい直径を有する中実の半球状頭部6cと、挿入管1の先端部の内径よりも僅かに小さな外径の円筒状部9aとからなり、該円筒状部9aの外周面には、図7に示されるように、軸線方向に複数本(3本)の突条9bが形成されている。突条9bの数は2本以上であればよいが、閉塞部材5cの円筒状部9aを挿入管1の先端開口部に安定して嵌挿するためには、3本以上とすることが好ましい。このように円筒状部9aの外周面に軸線方向に複数本の突条9bが形成されているため、閉塞部材5cの円筒状部9aと挿入管1の先端部内周面との間の摩擦力が軽減し、挿入管の先端開口部への着脱性に優れたものになると共に、円筒状部9aの外周面と挿入管1の先端部内周面との間に形成される空隙部S(ギャップ)は空気抜け部として機能する。また、閉塞部材の半球状頭部6cと挿入管1の先端部の外径がほぼ等しいため、遺体の体腔内への挿入管1の挿入性に優れていると共に、挿入操作のやり直し性にも優れている。   6 and 7 show a preferred embodiment of the closure member of the present invention. In this embodiment, the blocking member 5 c includes a solid hemispherical head 6 c having a diameter substantially equal to the outer diameter of the insertion tube 1 and a cylinder having an outer diameter slightly smaller than the inner diameter of the distal end portion of the insertion tube 1. As shown in FIG. 7, a plurality of (three) protrusions 9b are formed in the axial direction on the outer peripheral surface of the cylindrical portion 9a. The number of protrusions 9b may be two or more. However, in order to stably insert the cylindrical portion 9a of the closing member 5c into the distal end opening of the insertion tube 1, it is preferable to use three or more. . As described above, since a plurality of protrusions 9b are formed in the axial direction on the outer peripheral surface of the cylindrical portion 9a, the frictional force between the cylindrical portion 9a of the closing member 5c and the inner peripheral surface of the distal end portion of the insertion tube 1 is obtained. Is reduced, and is excellent in detachability to the distal end opening of the insertion tube, and the gap S (gap) formed between the outer peripheral surface of the cylindrical portion 9a and the inner peripheral surface of the distal end portion of the insertion tube 1 ) Functions as an air vent. Further, since the outer diameters of the hemispherical head 6c of the closing member and the distal end portion of the insertion tube 1 are substantially equal, the insertion tube 1 is excellently inserted into the body cavity of the corpse, and the re-execution of the insertion operation is also possible. Are better.

前記実施態様の挿入管の使用に際して、図1に示すように、挿入管1の接続部に注入器20の吐出筒部22を嵌め合わせて挿入管1と注入器20を接続し、挿入管1の先端に装着されている閉塞部材5cを鼻孔A(図1参照)又は口から咽喉部Bに向けて挿入し、所定位置で挿入を停止した状態で注入器20内の体液漏出防止剤Xをピストン24により押し出すと、その前進方向(軸線方向)の押圧力により、まず最初に挿入管1内の空気が押されることによって閉塞部材5cが僅かに前進し、それによって閉塞部材5cの半球状頭部5cと挿入管1の先端面との間に隙間が生じる。そのため、挿入管1内の空気は、この隙間と、円筒状部9aの外周面と挿入管1の先端部内周面との間に形成された空隙部Sを通して挿入管内から押し出され、次いでピストン24により先端部まで押し出された体液漏出防止剤Xの押圧力によって、閉塞部材5cが挿入管1の先端部から外れる。閉塞部材5cが挿入管1の先端部から外れると同時に、ピストン24により押し出される体液漏出防止剤Xの半径方向の押圧力は環状周壁部に作用し、複数の切れ目3(又はスリット3a)間に形成される舌片4(図2〜4参照)が側方に押されてラッパ状に拡開し、体腔内を押し広げるように作用する。そのため、スムーズに体液漏出防止剤を注入・装填することができ、比較的短時間の処理で充分な量の体液漏出防止を注入できる。閉塞部材5c及び注入器20内の体液漏出防止剤Xを押出し、充填した後は、注入器20と挿入管1を鼻孔A又は口から抜き出す。   When using the insertion tube of the above-described embodiment, as shown in FIG. 1, the insertion tube 1 and the injector 20 are connected by fitting the discharge tube portion 22 of the injector 20 to the connection portion of the insertion tube 1, and the insertion tube 1. The occlusion member 5c attached to the tip of the body is inserted from the nostril A (see FIG. 1) or the mouth toward the throat B, and the body fluid leakage preventing agent X in the injector 20 is inserted in a state where the insertion is stopped at a predetermined position. When pushed out by the piston 24, the blocking member 5c is slightly moved forward by first pushing the air in the insertion tube 1 due to the pressing force in the advance direction (axial direction), thereby the hemispherical head of the blocking member 5c. A gap is generated between the portion 5 c and the distal end surface of the insertion tube 1. Therefore, the air in the insertion tube 1 is pushed out of the insertion tube through the gap S formed between the gap and the outer peripheral surface of the cylindrical portion 9a and the inner peripheral surface of the distal end portion of the insertion tube 1, and then the piston 24 The blocking member 5c is detached from the distal end portion of the insertion tube 1 by the pressing force of the bodily fluid leakage preventing agent X pushed out to the distal end portion. At the same time that the blocking member 5c is detached from the distal end portion of the insertion tube 1, the pressing force in the radial direction of the body fluid leakage preventing agent X pushed out by the piston 24 acts on the annular peripheral wall portion, and between the plurality of cuts 3 (or slits 3a). The formed tongue piece 4 (see FIGS. 2 to 4) is pushed to the side to expand in a trumpet shape, and acts to push the inside of the body cavity. Therefore, the bodily fluid leakage prevention agent can be injected and loaded smoothly, and a sufficient amount of bodily fluid leakage prevention can be injected in a relatively short time. After the body fluid leakage preventing agent X in the blocking member 5c and the injector 20 is extruded and filled, the injector 20 and the insertion tube 1 are extracted from the nostril A or the mouth.

尚、前記した挿入管1(1a)の後端部には、前記図1に示されるような注入器20の吐出筒部22に接続するための後側にやや拡開したテーパ状の接続部(図示せず)が設けられている。また、接続部もしくはその近傍に、前記図1に示される挿入管10のような環状のストッパ部13を形成してもよい。但し、注入器20の筒状本体21の外径は挿入管1(1a)の外径や鼻孔や口等の挿入部の開口径よりも大きいため、注入器20の筒状本体21の先端部を挿入のストッパ部として利用することができ、体腔内に常に一定長さだけ挿入できるので、必ずしもストッパ部13が形成されていなくてもよい。また、前記注入器20の少なくとも吐出筒部22が着色されていて、上記挿入管1(1a)が透明もしくは半透明である場合、注入操作時に、注入器20の吐出筒部22先端の位置を目で確認できるので、この吐出筒部先端の位置を挿入停止位置を示すマークとして利用できる。さらに、環状のストッパ部13に代えて、接続部もしくはその近傍に挿入停止位置を示す黒色又は着色の環状の指示線もしくは環状帯等を設けることもできる。さらに、鼻孔や口から咽頭部奥まで挿入する際、抵抗なくスムーズに挿入することができるように、挿入管1の略中間部に湾曲部を形成することもできる。尚、注入操作時に、注入器の先端から挿入管が抜け出ることを確実に防止するために、前記注入器20の吐出筒部22と挿入管1の接続部に、雄ねじと雌ねじの組合せ、円周方向の溝部と該溝部に嵌合される突条もしくは凸部との組合せなどの抜け止め防止手段を設けてもよい。   In addition, a taper-like connecting portion that is slightly expanded on the rear side for connecting to the discharge tube portion 22 of the injector 20 as shown in FIG. 1 is provided at the rear end portion of the insertion tube 1 (1a). (Not shown) is provided. Moreover, you may form the cyclic | annular stopper part 13 like the insertion pipe 10 shown by the said FIG. 1 in the connection part or its vicinity. However, since the outer diameter of the cylindrical main body 21 of the injector 20 is larger than the outer diameter of the insertion tube 1 (1a) and the opening diameter of the insertion portion such as a nostril or mouth, the distal end portion of the cylindrical main body 21 of the injector 20 Can be used as a stopper for insertion and can always be inserted into the body cavity by a certain length, so that the stopper 13 does not necessarily have to be formed. Further, when at least the discharge cylinder portion 22 of the injector 20 is colored and the insertion tube 1 (1a) is transparent or translucent, the position of the tip of the discharge cylinder portion 22 of the injector 20 is set during the injection operation. Since it can be visually confirmed, the position of the tip of the discharge cylinder can be used as a mark indicating the insertion stop position. Further, instead of the annular stopper portion 13, a black or colored annular indicator line or annular band indicating the insertion stop position may be provided at or near the connection portion. Furthermore, when inserting from the nostril or mouth to the back of the pharynx, a curved portion can be formed at a substantially intermediate portion of the insertion tube 1 so that the insertion can be smoothly performed without resistance. In order to reliably prevent the insertion tube from coming off from the tip of the injector during the injection operation, a combination of a male screw and a female screw is provided at the connection portion between the discharge tube portion 22 and the insertion tube 1 of the injector 20 and the circumference. You may provide prevention means, such as a combination of a groove portion in the direction and a ridge or projection fitted in the groove portion.

前記図6及び図7に示した閉塞部材は、前記した先端部に切れ目やスリット等の線状切断部が形成されている挿入管に好適に用いることができるだけでなく、このような線状切断部が形成されていない他の体液漏出防止剤注入用挿入管の先端開口部を閉塞するのにも好適に用いることができる。その一つの実施態様を図8に示す。   The closing member shown in FIGS. 6 and 7 can be suitably used not only for an insertion tube in which a linear cutting part such as a cut line or a slit is formed at the above-mentioned distal end part. It can also be suitably used to close the tip opening of another insertion tube for injecting a body fluid leakage preventing agent that is not formed with a portion. One embodiment is shown in FIG.

図8に示す実施態様においては、先端開口部に前記閉塞部材5cが嵌挿された挿入管1bは、その先端部近傍の周壁に側孔12a(図示の例では2個所の対向する位置にそれぞれ一対(合計4個)設けられているが、1個又は任意の複数個でよい)が形成されており、且つ、略中間部に湾曲部Yが形成されている。このような側孔12aを形成することにより、挿入管先端部に切れ目やスリット等の線状切断部が形成されていなくても、体液漏出防止剤注入用の充分な開口面積を確保できる。また、湾曲部Yを形成することにより、鼻孔や口から咽頭部奥まで挿入する際、抵抗なくスムーズに挿入することができる。湾曲部Yは、挿入管1bの先端から徐々になだらかに湾曲させてもよいが、好ましくは挿入管1bの先端から所定位置、例えば約22〜45mm、より好ましくは約20〜30mmの距離の任意の部分から徐々になだらかに湾曲させることが好ましい。また、湾曲部Yの曲率半径や角度は、鼻孔や口蓋の曲面形状に対応することが好ましい。   In the embodiment shown in FIG. 8, the insertion tube 1b in which the closing member 5c is inserted into the distal end opening portion is provided with side holes 12a (in the illustrated example at two opposing positions) in the peripheral wall near the distal end portion. A pair (four in total) may be provided, but one or any plural number may be formed, and a curved portion Y is formed in a substantially middle portion. By forming such a side hole 12a, a sufficient opening area for injecting the bodily fluid leakage preventing agent can be ensured even if a linear cutting portion such as a cut line or a slit is not formed at the distal end portion of the insertion tube. Further, by forming the curved portion Y, it can be smoothly inserted without resistance when inserted from the nostril or mouth to the back of the pharynx. The bending portion Y may be gradually and gradually curved from the distal end of the insertion tube 1b, but preferably at a predetermined position from the distal end of the insertion tube 1b, for example, an arbitrary distance of about 22 to 45 mm, more preferably about 20 to 30 mm. It is preferable to gradually and gently curve from this part. Moreover, it is preferable that the curvature radius and angle of the curved part Y respond | correspond to the curved surface shape of a nostril or a palate.

尚、図8に示す実施態様の変形例として、挿入管1bの先端部近傍の周壁に側孔12aが形成され、湾曲部Yを有しない直線状とすることもできる。また、接続部11もしくはその近傍に、前記図1に示される挿入管10のような環状のストッパ部13を形成してもよい。さらに、環状のストッパ部に代えて、接続部11もしくはその近傍に挿入停止位置を示す黒色又は着色の環状の指示線もしくは環状帯等を設けることもできる。さらに、注入操作時に、注入器の先端から挿入管が抜け出ることを確実に防止するために、前記注入器20の吐出筒部22と挿入管1bの接続部11に、雄ねじと雌ねじの組合せ、円周方向の溝部と該溝部に嵌合される突条もしくは凸部との組合せなどの抜け止め防止手段を設けてもよい。   As a modification of the embodiment shown in FIG. 8, the side hole 12a is formed in the peripheral wall in the vicinity of the distal end portion of the insertion tube 1b, and the straight shape without the curved portion Y can be used. Moreover, you may form the cyclic | annular stopper part 13 like the insertion pipe 10 shown in the said FIG. 1 in the connection part 11 or its vicinity. Furthermore, instead of the annular stopper portion, a black or colored annular indicator line or annular band indicating the insertion stop position can be provided at or near the connection portion 11. Further, in order to reliably prevent the insertion tube from slipping out of the tip of the injector during the injection operation, a combination of a male screw and a female screw, a circular shape is provided on the discharge cylinder portion 22 of the injector 20 and the connection portion 11 of the insertion tube 1b. You may provide prevention means, such as the combination of the circumferential groove part and the protrusion or convex part fitted to this groove part.
