Description
本出願は、2004年12月9日出願の米国仮特許出願番号60/634,486の優先権を主張する。又、本出願は、本出願と共通に所有され又帰属される2003年6月20日出願の米国特許出願番号10/601,212に関連するものである。これら両方の内容は引用をもって本出願に組み込まれる。
1.発明の分野
本開示は、自動注入及び引き込みシリンジ(注射器)に関するものである。より詳しくは、本開示は、互いに選択的に接続可能な引き込みアセンブリと注入アセンブリとを有する自動注入及び引き込みシリンジに関するものである。
エイズ、肝炎などの病気が一般の人たちの間で増加している。これらの病気の出現は、シリンジアセンブリの使用中における不慮の針刺しを防止することに対する要望を増大させた。多くの従来の装置は、不慮の針刺しを軽減するために自己引き込み針を有する。
本開示の目的の1つは、選択的に接続可能な注入アセンブリと引き込みアセンブリとを有する自動注入及び引き込みシリンジを提供することである。
図面、特に、図1〜図3を参照すると、本開示に従うシリンジ10の典型的な実施形態が示されている。シリンジ10は、注入アセンブリ12、薬剤カートリッジ14、及び引き込みアセンブリ16を有する。
