摘要:
PROBLEM TO BE SOLVED: To provide an access port fixed to a biomembrane such as a pericardium in a state of penetrating through the biomembrane.SOLUTION: An access port 1 includes: an inner tube 2 and an outer tube 3 relatively movably fitted together in an axial direction, where the outer tube 3 has holding surfaces 7a of a substantially complementary shape that are made to approach to/separate from each other by the relative movement of the inner tube 2 and the outer tube 3 a strip-like draw-in member 7 composed of an elastic material whose one end is fitted to a tip end of the outer tube 3 and a storage part 8 at the tip end of the inner tube 2 for storing the draw-in member 7, with it laid along the outer surface of the outer cylinder 3, where the holding surfaces 7a are composed of a surface of the draw-in member 7 in a state stored in the storage part 8.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2017,JPO&INPIT【課題】心膜のような生体膜に対して、該生体膜を貫通した状態で固定する。【解決手段】軸方向に相対移動可能に嵌合された内筒2および外筒3を備え、外筒3が、内筒2と外筒3との相対移動によって、近接または離間させられる略相補的な形状の挟持面7aを有し、外筒3の先端に一端が取り付けられた弾性材料からなる短冊状の引き込み部材7が設けられ、内筒2の先端に、引き込み部材7を外筒3の外面に沿わせた状態で収納する収納部8が設けられ、挟持面7aが、収納部8に収納状態の引き込み部材7の表面により構成されるアクセスポート1を提供する。【選択図】図7
