摘要：
One embodiment is directed to a system for injecting, 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 such that upon retraction of the stopper member, the needle is pulled proximally along with the stopper 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.
