摘要：
One embodiment is directed to a safety syringe system, comprising: an off-the-shelf syringe assembly comprising a syringe body and a plunger tip； a needle assembly removably coupleable to the distal end of the syringe body such that 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 of the plunger tip to a final insertion state and release of an associated manual insertion load, the plunger tip may be proximally withdrawn, pulling the retractable needle proximally relative to the needle housing to a safe locked and retracted state wherein it is no longer exposed for injection.
