Description
また、シースの開口部の内部に収容されたカニューレを、成型が容易な固定タブによって固定することができる。つまり、カニューレ固定部を低コストで実現することができる。
さらに、シースがこのような溝部と傾斜面を備えた一対の翼壁部とを有することによる高い操作性を実現することができる。つまり、シースの本体部分から突き出た翼壁部は外側にたわみやすく、また、傾斜面によってカラーのシース固定用突起部を溝部まで受け入れやすく、さらに、溝部によってシース固定用突起部を固定でき、これらにより、ユーザがシースを指で押すときに比較的小さな力でシースの翼壁部の溝部とカラーのシース固定用突起部を嵌合および固定させることができる。
ハブ1の外面は、ハブ1の外側円周表面から径方向外側に延びる突起部14を複数備える。
また、環状凹部領域15が、突起部14の遠位側に位置している。したがって、環状凹部領域15に隣接する段部分16、17は、環状凹部領域15の外径よりも大きな外径を有する。
カラー3は、一対のシース固定用突起部35を備える。シース固定用突起部35は、略三角形状で、耳部31とは反対の位置に設けられており、シース5の翼壁部53(カニューレ固定部)と嵌合する溝部37を有する。
指案内部51の背面壁は、ユーザの指との摩擦を増やすための凸部510と凹部511が繰り返し設けられた階段状の、前方へ下り傾斜する斜面部となっている。
まず、ユーザは、プロテクタ4を取り外すことができるように、シース5を回転移動させてプロテクタ4から遠ざける。
カニューレ2の使用を終えたユーザは、まず、シース5をカニューレ2に向かって回転移動させ、安全針アセンブリ100を図8に示す状態とする。
例えば、長さの異なる複数のカニューレ2がある場合、それぞれの長さに合わせたシース5を用いてもよい。
その他、具体的な構成について、本発明の主旨を逸脱しない範囲で適宜変更が可能である。
