Description
薬剤送達機構は、針後退ロック73をさらに含む。針後退ロック73は、針後退ばね74と、後退保持要素75と、一対の後退ロッキング部材(図示せず)とを有する。針後退ロック73は、本発明の第1の実施形態の薬剤送達デバイス10の針後退ロック37に類似している。違いは、第2の実施形態の薬剤送達デバイス60の後退ロッキング部材は、ハウジング61の遠位部分16ではなく可撓性バッグ63に回転可能に取り付けられることである。したがって、針後退ロック73がロック状態にあるとき、ハウジング61の中心軸A-Aの方向における可撓性バッグ63の動きが対応それに対応した針62の変位を引き起こす。したがって、近位部分17が初期位置から準備完了位置へと動かされると、可撓性バッグ63およびプレート64は、遠位部分16の端壁19の方に向けて動き、針62も遠位部分16の端壁19の方に向けて動く。
