Description
Claims (12)
- 自動注射デバイスであって:
遠位端および近位端を有するハウジングと;
該ハウジングの中に配置された薬剤カートリッジと;
針を含むニードルユニットであって、ハウジングの遠位端に配置されているニードルユニットと;
ハウジングの近位端に配置されたボタンであって、ボタンが初期位置から押し下げ位置まで押されたときに、カートリッジに直接作用してカートリッジをニードルユニットまで動かし、それによって針をカートリッジと流体連結するように構成されるボタンと;
薬剤をカートリッジから送り出して針に通すように変位可能なプランジャと;
プランジャを変位させるためのプランジャ機構と;
スリーブが針を覆い隠す第1の位置と、針がスリーブの端部から露出する第2の位置との間で、デバイスの長手方向軸に沿って変位可能であるスリーブであって、該スリーブが第1の位置から第2の位置まで動くとプランジャ機構をトリガするように構成されているスリーブと
を含む、前記自動注射デバイス。 - ボタンは、ボタンが初期位置から押し下げ位置まで押されるとプランジャ機構とカートリッジを同時に動かすように構成される、請求項1に記載の注射デバイス。
- スリーブは、ボタンが第1の位置にあるときに、プランジャ機構から軸方向に離間され、ボタンは、該ボタンが初期位置から押し下げ位置まで押されるとプランジャ機構を動かしてスリーブと当接関係になるように構成される、請求項2に記載の注射デバイス。
- プランジャ機構は、付勢部材およびカラーを含み、カラーは、付勢部材がカラーによって所定の位置にロックされるロック位置と、付勢部材がプランジャを自由に変位させるロック解除位置との間で長手方向軸のまわりに回転可能であり;スリーブは、該スリーブが第1の位置から第2の位置まで動くとカラーを回転させるように構成される、請求項1~3のいずれか1項に記載の注射デバイス。
- スリーブは、ボタンが押し下げ位置にあるときにカラーに当接する、請求項4に記載の注射デバイス。
- ボタンが初期位置にあるときにスリーブの変位を防止するように構成されたロッキング機構をさらに備える、請求項5に記載の注射デバイス。
- ロッキング機構は、デバイスの壁から垂下するフックを含む、請求項6に記載の注射デバイス。
- フックは、ボタンが初期位置にあるときにスリーブに当接して、スリーブがハウジングに対して動かないようにする、請求項7に記載の注射デバイス。
- ボタンは、初期位置から押し下げ位置まで動くときにフックに作用して、該フックがスリーブまたはカラーとの当接関係から脱して変位するように構成される、請求項7または請求項8に記載の注射デバイス。
- ボタンが初期位置にあるときに、ボタンに設けられた止め具は、ハウジングの縁部から離間されており;止め具と縁部の間に延びる安全クリップがボタンの動きを防止するために設けられており、その結果、安全クリップを除去しなければ、ボタンを押すことができない、請求項1~9のいずれか1項に記載の注射デバイス。
- ボタンは、デバイスの壁のL形スロットを通って延びる突起を備え、それにより、ボタンが初期位置にあるとき、突起は、長手方向軸に垂直に伸びるL形スロットの第1の部分に位置しており、ボタンが初期位置から押し下げ位置まで動くことを防止し、ボタンは回転可能であるので、ボタンは回転されて突起が、長手方向軸に平行に延びるスロットの第2の部分と位置合わせされ、ボタンが押し下げ位置まで動くことを可能にすることができる、請求項1~9のいずれか1項に記載の注射デバイス。
- 薬剤カートリッジ内に薬剤のリザーバをさらに含む、請求項1~11のいずれか1項に記載の注射デバイス。
