Description
これにより、シール部材18の駆動時における圧力の蓄積を防止できて、シール部材18とカテーテルハブ12の内壁25との間における接触表面積を低減することができ、これにより、そのような駆動時にシール部材18に対して印加される摩擦力を最小化することができる。
これにより、シール部材18に対して接触させることなくまたシール部材18を損傷させることなく、メンブラン72内にスリット82を形成することができる。
とができる。このようにして、チューブは、スリット82を通してのニードルカニューレ40の挿入時には、メンブラン72とニードルカニューレ40との間のバリアとして機能する。これにより、組立時における損傷の傾向を回避または低減させることができる。
ことは、理解されるであろう。シール部材が、ここでは有利であるように、1回使用タイプのシールである場合には、そのような変形または損傷は、問題とはならない。さらに、シール部材18は、図示の例示としての一実施形態においては、一体部材として説明されているけれども、代替可能な実施形態においては、シール部材は、複数の部材からなる構成を有することができる。例えば、シール部材は、弾性的なシール部分に対して連結された剛直な保持部材分を備えることができる。剛直な保持部材分は、全体的に円筒形のものとすることができて穴92のようなノーズ受領穴を備えているという点において、上述したシール部材18の基端部76と同様のものとすることができる。弾性シール部分は、上述したシール部材18のメンブラン72および先端部74と同様のものとすることができる。弾性シール部分は、保持部分の先端に対して連結することができ、保持部分と合わせて、上記のシール部材18と同様の形状を有することができる。剛直な保持部材分は、オス型ルアーテーパー30からの衝撃によって印加された応力および力を受領し得るよう構成されている。一方、弾性シール部分は、止血機能をもたらし得るよう構成されており、駆動時にはメンブラン72を通してアクチュエータ16のバーブ50を通過させ得るよう構成されている。したがって、本発明は、広義の見地においては、図示されて上述された特定の細部や装置や方法や実施例に限定されるものではない。したがって、本発明の一般的概念の精神または範囲を逸脱することなく、そのような細部に対して変更を行うことができる。
