Abstract
【解決手段】 体内留置具Aを、瘻孔に設置される筒状部材11と、胃内に設置される内部保持部材20とで構成した。そして、内部保持部材20を、筒状部材11の先端開口縁部から外部側先方に向かって湾曲して延びたのちに先端部が結合された可撓性を有する帯状部材22a,22bと、帯状部材22a等の筒状部材11側部分に設けられ、帯状部材22a等とでドーム状部分を形成する可撓性を有する膜状部材23a,23bとで構成した。また、膜状部材23a等の外周縁部25a中央に切欠き部26a,26bを設け、切欠き部26a等から筒状部材11側に延びる折り曲げ用溝部27a等と、膜状部材23a等の外周縁部25aから筒状部材11側に延びる折り曲げ用溝部28a等を設けた。
【選択図】 図2
Description
以下、本発明の第1実施形態を図面を用いて説明する。図1は、同実施形態による体内留置具Aを示している。この体内留置具Aは、患者の腹部と胃壁との間に形成された瘻孔に設置されて流動食等の流体物を胃内に供給するために用いられるものであり、それぞれポリウレタンからなる外部保持部材10と、外部保持部材10の下端に連結された筒状部材11と、筒状部材11の下端に取り付けられた内部保持部材20とで構成されている。以下、外部保持部材10側を上側、内部保持部材20側を下側として説明する。
図12は、本発明の第2実施形態に係る体内留置具Bを示しており、図13ないし図15は、体内留置具Bが備える内部保持部材40を示している。この内部保持部材40は、筒状の接続部41と、4個の帯状部材42a,42b,42c,42dと、4個の膜状部材43a,43b,43c,43dと、結合部材44とで構成されている。接続部41は、前述した体内留置具Aの接続部21と同じ構成になっている。帯状部材42a,42b,42c,42dは、接続部41の下端外周面に連結されており、それぞれ接続部41の外周面から外側に向かって四方に延びたのちに屈曲して下方から接続部41の真下に向かって延びる湾曲状に形成されている。
図17は、本発明の第3実施形態に係る体内留置具が備える内部保持部材50を上から見た状態を示している。この内部保持部材50では、図13に示した内部保持部材40における帯状部材42a,42cに該当する部分が幅の狭い(細い)帯状部材52a,52cで構成されている。この内部保持部材50を備えた体内留置具のそれ以外の部分の構成については、前述した体内留置具Bと同一である。したがって、同一部分に同一符号を記して説明は省略する。この場合、内部保持部材50が伸張されると、その平面視による形状は、図18に示したようになる。この場合も体内留置具の瘻孔への挿入や抜き取りが容易に行えるようになる。
