Summary:To provide a system and method for drug delivery with a safety syringe.SOLUTION: One embodiment is directed to a system for injection, comprising: a syringe body defining an interior medicine chamber; a stopper member configured to be inserted into the interior medicine chamber to contain medicine within the medicine chamber; a plunger member configured to be manually manipulated to insert the stopper member relative to the syringe body; a needle having proximal and distal ends, the proximal end comprising an anchoring geometry configured to be at least partially penetrated into the stopper member, so that, upon retraction of the stopper member, the needle is pulled proximally along with the stopper so as to be at least partially contained within the interior medicine chamber; and an energy-storing member operatively coupled between the stopper member and the syringe body, the energy-storing member configured to facilitate retraction of the stopper member relative to the syringe body.SELECTED DRAWING: Figure 6A 【課題】安全注射器を用いた薬品送達のためのシステムおよび方法を提供すること。【解決手段】一実施形態は、内部薬品チャンバを画定する注射器本体と、内部薬品チャンバの中に挿入され、薬品チャンバ内に薬品を封じ込めるよう構成されるストッパ部材と、ストッパ部材を注射器本体に対して挿入するために手動で操作されるよう構成されるプランジャ部材と、近位および遠位端を有する針であって、近位端は、ストッパ部材の中に少なくとも部分的に穿通させられるように構成される係留幾何学形状を備え、それによって、ストッパ部材の後退時、針は、ストッパとともに近位に引っぱられ、内部薬品チャンバ内に少なくとも部分的に含まれる、針と、ストッパ部材と注射器本体との間に動作可能に結合されるエネルギー貯蔵部材であって、注射器本体に対するストッパ部材の後退を促進するよう構成される、エネルギー貯蔵部材とを備える、注射のためのシステムに関する。【選択図】図6A
