Abstract
Description
先端に鋭利な針先を有する内針と、
該内針の基端部に固定された内針ハブと、
前記内針が挿通される中空の外針と、
該外針の基端部に固定された外針ハブと、
前記内針ハブに挿通され、かつ、前記外針ハブの基端部に、内腔が前記外針の内腔と連通するように接続されたチューブとを有し、
前記内針を前記外針に挿通した状態で、前記外針の中心軸と前記チューブの先端部における中心軸とがほぼ平行となるように構成されていることを特徴とする留置針組立体である。
前記内針を前記外針に挿通した状態で、前記内針の外径が最も小さい部分が前記シール部材の前記孔内に位置するのが好ましい。
該中継流路は、前記シール部材に形成された流路と前記外針ハブの側壁部に形成された流路とが連通することにより完成しているのが好ましい。
前記内針を前記外針に挿通した状態で、前記プロテクタは、前記シール部材より基端側に位置するのが好ましい。
前記内針を前記内針通路に挿通可能な第1の姿勢と前記内針の針先の通過を阻止する第2の姿勢とに変位するシャッター手段とを備えるのが好ましい。
前記プロテクタ本体は、前記内針通路の内径が縮径する縮径部を有し、
前記係合手段は、前記内針の外径が変化する部分と前記縮径部とで構成されているのが好ましい。
前記内針を前記外針から抜去した際に、前記チューブを前記内針ハブから前記スリットを介して取り外すことができるように構成されているのが好ましい。
まず、固定手段について説明する。
次に、係合手段について説明する。
