Description
本発明は安全な注射針構造に関するものであり、注射針による不測の傷害の危険を軽減する。特に、ハブ内に注射針型カニューレ(套管)が組込まれている安全な注射針構造に関するものである。
注射針は、通常、人体又は動物に物質を注入するため、又は抽出するためのどちらかに使用される。このような注射針は一般に使い捨て型であり一回だけの使用で破棄される。
注射針の使い捨てによる、或いは、注射針の操作に起因して発生する問題点は注射針型カニューレの鋭利な先端によって傷つけられるという潜在的な危険性である。このような事故は注射針が患者の皮膚を貫いた後に発生した場合には特に深刻である。注射針型カニューレがその時に汚染されている可能性があり、それによって肝炎やHIVのような病気を広める場合があるからである。
ハブに取り付けられている回転可能なカム部材は少なくとも一つのカムを備え、このカムは保護筒の内側面に設けられているカム曲線で誘導される。保護筒はハブと保護筒の間に挿入されているスプリングによって遠端部側方向に押されている。カム曲線は、注入が行われた後に保護筒が第一の位置に戻る際に、阻止位置にカムを固定するように用いられる。
それ故、先行技術による安全な注射針構造の不都合面を克服した安全な注射針構造を提供することが本発明の目的であり、特に、より少ない部品数で構成され、これらの部品に対し極端に厳しい許容誤差を求めない安全な注射針構造を提供することが本発明の目的である。
先ず、「遠端部」という文言は本安全な注射針構造の患者に挿入される側の終端部を意味し、他方、「近端部」という文言は注入器に結合される側の終端部を意味することを定義しておくことが便利であろう。
