Abstract

留置針組立体（１）は、中空の外針と、外針の基端部に固定された外針ハブ（３）と、外針内に挿通される内針（４）と、内針（４）の基端部に固定された内針ハブ（５）と、外針ハブ（３）の基端部（または側方部）に、内腔が外針の内腔（２１）と連通するように接続されたチューブと、内針（４）を外針から抜去した際に、内針（４）の少なくとも針先を覆い、外針ハブ（３）に対して着脱自在に連結されるプロテクタ（９）とを有している。プロテクタ（９）のプロテクタカバー（９２）には、内針（４）に対して外針を先端方向に移動させるために指で押圧する指当部（６）が、突出形成されている。指当部（６）は、内針（４）に対して外針を先端方向に移動させる際、外針の中心軸（Ｏ１）に対して指当部（６）の突出する方向の力が指当部（６）に作用し得る形状をなしている。
