〔産業上の利用分野〕
本考案は生体の内部と外部とを開通するための
開通部材に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an opening member for opening the inside and outside of a living body.
生体の内部と外部とを開通することは、人工臓
器の発達、あるいは排泄物の導出など外科手術の
進展などに伴つてますますその必要性が高まつて
きた。
The need to open the inside and outside of a living body has increased with the development of artificial organs and advances in surgical procedures such as the removal of excreta.
このための開通部材としてはすでに特開昭59−
146662号、特開昭59−146635号などで提案されて
おり、これらは円筒状を成し、生体親和性をもつ

をもつたものなどがすでに提案されている。 The opening member for this purpose was already developed in JP-A-59-
No. 146662, Japanese Patent Application Laid-Open No. 146635, etc., these are cylindrical, made of biocompatible material, and have an axial opening in the center. The thing was disclosed, JP-A-61-
No. 179163 has already proposed a device that is made of apatite-based material and has a structure in which two connecting bodies are press-fitted from inside and outside the body.
ところが、その目的からして、生体内外開通部
材は長い期間にわたつて生体に設置する性質上、
生体組織との接合部が完全に瘉着した状態で清潔
に保たれることが重要である。
However, due to the nature of the in-vivo and in-vivo opening members being placed in the living body for a long period of time,
It is important that the joint with living tissue is kept completely adhered and clean.
このためには皮膚（生体）との親和性に優れ、
接合部に汚物がたまりにくく、たまつた汚れが取
り除き易い形状であることが要件であつた。 For this purpose, it has excellent affinity with the skin (living body),
The requirements were that the joints should have a shape that would prevent dirt from accumulating and would make it easy to remove accumulated dirt.
しかし、従来のものでは上記要件をある程度満
足するものである反面、生体内、外において、特
に生体外において開通部材の開通孔に連結せしめ
るパイプとの連結（接続）性が劣つていた。 However, while conventional devices satisfy the above requirements to some extent, they have poor connectivity with a pipe connected to the opening of the opening member, both in vivo and outside the body, especially outside the living body.
このため、寝たきりの病人や運動機能の低下し
た人が身体の一部に装着された開通部材にパイプ
を独自に接続したり、取外したりすることが難い
傾向にあり、介護者による手助けを必要とするこ
とが多かつた。 For this reason, it tends to be difficult for bedridden patients and people with reduced motor skills to independently connect or disconnect pipes from opening members attached to parts of their bodies, and they often require assistance from caregivers. There was a lot to do.
上記問題点を解決すべく、開通孔を備えた開通
部材に対し、手術時における生体内におけるパイ
プの接続性、及びその後における生体外における
パイプとの接続性を向上させ、かつ安定した接続
状態を維持すべく開通部材の両端部の体内突出部

る。
In order to solve the above-mentioned problems, we improved the connectivity of the pipe in the living body during surgery and the connectivity with the pipe outside the living body at the time of surgery, and created a stable connection state for the opening member equipped with the opening hole. It is characterized in that the in-body protrusion and the out-of-body protrusion at both ends of the opening member are tapered in order to maintain the condition.
以下、図によつて本考案実施例を説明する。 Embodiments of the present invention will be described below with reference to the drawings.

となく、安定的に装着できるようになつている。 Figures 1 and 2 show the in-vivo and in-vivo opening member
This opening member 1 has an approximately cylindrical shape with an opening hole 2 formed therein, and one end of the opening member 1 protrudes outside the living body. A tapered external protrusion 1a, and a tapered internal protrusion 1 protruding into the living body at the other end.
b is formed, and an enlarged part 1c with a large diameter in the circumferential direction is integrally formed in the center of the opening member 1, and this enlarged part 1c allows for stable attachment without detachment from the living body. I'm starting to be able to do it.
また上記体外突出部１ａ、体内突出部１ｂには
パイプＰ（第３図）の接続安定性をもたせるべく
凸条環１a′，１b′がそれぞれ形成してある。 Furthermore, protruding rings 1a' and 1b' are formed on the externally protruding portion 1a and the internally protruding portion 1b, respectively, in order to provide connection stability for the pipe P (FIG. 3).

し易すさ、安定性の面から好適であつた。 The opening member 1 configured as described above is attached to the living body B as shown in the cross-sectional view in FIG. Furthermore, by connecting the pipe P 2 outside the body to the external protrusion 1a, the pipes P 1 and P 2 are brought into communication via the opening member 1, and the pipe P 1 and P 2 are connected to the pipe P 1 and P 2 through the opening member 1. It can be used to drain excreta, to inject medicinal fluids from outside the body, or to pass electrical wires, optical fibers, etc. Incidentally, a taper angle of about 2 to 15 degrees is suitable for forming the protrusions 1a and 1b into a tapered shape from the viewpoint of ease of insertion and stability of the pipes P1 and P2 .
