Description
Claims (13)
- 注射デバイスであって:
薬剤カートリッジを受け入れるためのハウジングと;
針を含む針ユニットと;
ハウジングの長手方向軸に沿って、第1のスリーブが針を隠す第1の位置から、針が第1のスリーブの端部から露出される第2の位置に摺動可能な第1のスリーブとを含み、該第1のスリーブは、針ユニットに係合するように構成され、それにより、使用中、第1の位置から第2の位置への第1のスリーブの移動により針ユニットが一次位置から二次位置に移動し、該二次位置で、針ユニットは、薬剤カートリッジが該デバイス内に受け入れられるときに薬剤カートリッジの端部に被さって位置し、
該デバイスは、第1のスリーブに対して嵌め込み式で移動するように配置された第2のスリーブをさらに含み、第1のスリーブは、該第1のスリーブが第1の位置にあるときに第2のスリーブから延び、
該デバイスは、薬剤カートリッジから薬剤を押し出すために変位可能なプランジャと、該デバイスの動作中にプランジャを変位させるためにトリガ可能なプランジャ機構とをさらに含み、第1のスリーブまたは第2のスリーブのいずれかは、長手方向軸に沿った変位中にプランジャをトリガするように構成される、
前記注射デバイス。 - 第1のスリーブが第1の位置から第2の位置に移動されるとき、第1のスリーブは針ユニットから係合解除され、それにより第1のスリーブが針ユニットとは独立して移動することを可能にする、請求項1に記載の注射デバイス。
- 第1のスリーブおよび第2のスリーブは、使用中、第1のスリーブが長手方向軸に沿って変位されるとき、および第1のスリーブの端部が第2のスリーブの端部と面一になるときに針ユニットが薬剤カートリッジに係合するように配置される、請求項1または2に記載の注射デバイス。
- 第1の位置から、針ユニットが薬剤カートリッジに係合する位置への第1のスリーブの動きの範囲全体にわたって、針が隠される、請求項3に記載の注射デバイス。
- 針ユニットが薬剤カートリッジに係合する位置から第2の位置への第1のスリーブの動きの範囲全体にわたって、第2のスリーブは、第1のスリーブと同時に移動して針を露出させる、請求項4に記載の注射デバイス。
- 第2のスリーブの動きに抵抗するためにばねが提供される、請求項1~5のいずれか1項に記載の注射デバイス。

- 針ユニットは突起を含み、変位可能なアームは、対応する開口部を含み、該開口部を通って該突起がアームを針ユニットに接続するように位置することが可能である、請求項7に記載の注射デバイス。
- 突起の形状は、使用中、針ユニットが薬剤カートリッジに対して位置する状態で、第1のスリーブのさらなる軸方向運動により該突起がアームを長手方向軸から離れるように変位させ、針ユニットとの係合を解除させるようなものである、請求項8に記載の注射デバイス。
- アームは、開口部の遠位に細長いスロットを含み、アームのさらなる軸方向運動中に突起用のトラックを提供する、請求項9に記載の注射デバイス。
- 変位可能なアームの端部にはクリップがさらに設けられ、該クリップは、第1のスリーブが第2の位置にあるときに薬剤カートリッジの縁部を越えてロックするように構成される、請求項10に記載の注射デバイス。
- アームには、細長いスロットと開口部とを含むアームの一部分がクリップとは独立して移動することを可能にするために境界部が設けられている、請求項11に記載の注射デバイス。
