Summary: | To provide a system for mixing drug products and injecting.SOLUTION: A system includes a syringe body 34, proximal and distal stopper members 32 and 36 disposed in the syringe body, a plunger member, and a needle hub assembly coupled to a distal needle interface of the syringe body. The proximal and distal stopper members form a proximal drug chamber 40 therebetween and a distal drug chamber 42 between the distal stopper member and a distal end of the syringe body. The plunger member includes a needle retention structure, an energy-storage member, and an energy-storage member latching member, all disposed in a plunger interior. First and second sizes of the respective proximal and distal drug chambers can be modified by movement of the proximal and distal stopper members relative to the syringe body.SELECTED DRAWING: Figure 6-1
【課題】医薬品を混合し注射するシステムを提供する。【解決手段】注射器本体34と、注射器本体内に配置された近位および遠位ストッパ部材32、36と、プランジャ部材と、注射器本体の遠位ニードルインタフェースに結合されたニードルハブアセンブリを具えるシステム。近位および遠位ストッパ部材は、それらの間および遠位ストッパ部材と注射器本体の遠位端との間の遠位薬剤チャンバ42との間に近位薬剤チャンバ40を形成する。プランジャ部材は、ニードル保持構造と、エネルギー貯蔵部材と、エネルギー貯蔵部材ラッチ部材とを具え、これらはすべてプランジャ内部に配置されている。近位および遠位薬剤チャンバのそれぞれの第1および第2のサイズは、注射器本体に対する近位および遠位ストッパ部材の移動によって変えることができる。【選択図】図6-1 |
