摘要：
One embodiment is directed to a safety syringe system, comprising a syringe body; a plunger tip positioned within the syringe body; a needle assembly removably coupleable to the distal end of the syringe body such that a medicinal fluid may be transferred through a retractable needle coupled to a needle housing comprising the needle assembly upon insertion of the plunger tip relative to the syringe body; and a plunger control assembly coupled to the plunger tip and configured to facilitate manual insertion of the plunger tip relative to the syringe body; wherein upon insertion and release of the plunger tip, a retraction load coupled between the syringe body and the plunger tip causes the plunger tip to be proximally withdrawn, pulling the retractable needle proximally relative to the needle housing to a safe locked and retracted state.
摘要（中）：
一个实施例涉及一种安全注射器系统，包括注射器主体; 位于注射器主体内的柱塞头; 针组件可拆卸地联接到注射器主体的远端，使得药液可以通过可插拔针转移，所述可缩回针在相对于注射器主体插入柱塞尖端时包括针组件的针壳体; 以及柱塞控制组件，其联接到所述柱塞末端并且被配置为便于所述柱塞尖端相对于所述注射器主体的手动插入; 其中在插入和释放柱塞尖端时，联接在注射器主体和柱塞尖端之间的缩回负载使得柱塞尖端向近端缩回，将可缩回的针相对于针壳向近侧拉动到安全的锁定和缩回状态。
