Description
図1を参照して、本発明に係るシリンジは、本実施形態ではピストル形状の無針注射器である注射器2のために用いられ、全体で符号1により示されている。注射器2は、そのほぼ中央部から下方に延びるハンドル3を有する本体部を備えている。本体部は、上部シリンダー5と下部シリンダー6とにより構成されている。その上部シリンダー5及び下部シリンダー6のそれぞれは、注射器2の残りの構成要素の大半を含んでいる。注射器2の構成要素のうち、大半のものは、上記米国特許第7357915号に記載されている注射器の構成要素と同一又は類似である。
図9〜図11を参照して、本発明の第2実施形態は、内側端部64に一対の弓形の耳部63を有する管状の本体部62を備えている。耳部63は、図12に示されている注射器2のバレル66の一端部67にシリンジ1を取り付けるためのバヨネットカップリング(bayonet coupling)に用いられている。バレル66の開放された一端部67は、耳部63を受け入れるための対向した一対の凹部68を内部に備えている。耳部63が凹部68に嵌め込まれた後、本体部62は、シリンジ1を着脱自在にバレル66内に固定するために回転させられる。本体部62が固定位置まで回転させられたときには、耳部63の外側端部の小さな突起部69は、バレル66の一端部67の切欠き70に嵌め込まれる。本発明の第1実施形態と同様に、本体部62の外側端部71は、ルアーコネクタ(luer connector)に用いるためのオリフィス72とネジが形成された凹部73とを有する。
本発明の第3実施形態(図16〜図18)において、プランジャー74の外側端部80は、略円錐状のヘッド部91の円筒状の内側端部を保持する円筒状の凹部90を備えている。ヘッド部91は、環状の溝部92(図16)を有しており、チャンバー95の略円錐状の排出端である端部94は、環状の突起部96を有している。本発明に係る第2実施形態に(図13〜図15)おけるヘッド部86の場合と同様に、プランジャー74が伸張させられるときに(図17)、ヘッド部91は、チャンバー95の端部94に詰め込まれる。突起部96は、ヘッド部91の溝部92に結合する。それゆえ、プランジャー74が後退させられるときに(図18)、ヘッド部91がチャンバー95の排出端である端部94に残され、残されたヘッド部91がオリフィス72を閉塞する。
図19〜図21を参照して、本発明に係る第4実施形態において、プランジャー74の外側端部80は、外側端部80から分離可能なヘッド部99を支える細径の円筒状の突起部98を備えている。このため、ヘッド部99は、その内側端部内に凹部100を備えている。注射時に、ヘッド部99の円錐状の先端部102は、薬剤のチャンバー105の円錐状の排出端である端部103に詰め込まれて、オリフィス72を封止する。
Claims (4)

前記保持部は、前記オリフィスの背後に位置し、該オリフィスに接続され、前記プランジャーの先細り形状の前記外側端部と同じ形状を有し、前記プランジャーが押し込まれて前記オリフィスまで到達したときに、前記プランジャーの先細り形状の前記外側端部と結合する前記チャンバーの先細り形状の排出端部と、前記チャンバーの前記排出端部に設けられた環状の突起部と、環状の前記突起部と係合したときに前記プランジャーの先細り形状の前記先端部が圧縮可能となるように、前記プランジャーの先細り形状の前記先端部に設けられた長手方向に延びているスロットと、前記プランジャーの先細り形状の前記外側端部に設けられ、前記突起部を受け入れる環状の溝部とを有し、
環状の前記溝部が、先細り形状の前記外側端部に破断可能エリアを構成することによって、前記プランジャーの先細り形状の前記外側端部が前記チャンバーの前記排出端部に詰め込まれた後に後退させられたときに、前記プランジャーの先細り形状の前記先端部が、前記破断可能エリアで破断されて前記チャンバーの前記排出端部に残され、前記オリフィスを完全に閉塞することを特徴とする使い捨てシリンジ。 - 請求項1に記載の使い捨てシリンジであって、
前記プランジャーの先細り形状の前記外側端部の直径は、前記チャンバーの先細り形状の前記排出端部の直径と比べて同一又は僅かに大きく形成されていることを特徴とする使い捨てシリンジ。 - 請求項1に記載の使い捨てシリンジであって、
前記シリンジの前記無針注射器のバレル内への移動を規制する環状のフランジを、管状の前記本体部の前記閉塞端部に備えていることを特徴とする使い捨てシリンジ。 - 請求項3に記載の使い捨てシリンジであって、
前記プランジャーは、環状の前記フランジの後方の大半で、長手方向の横断面が十字形であることを特徴とする使い捨てシリンジ。
