发明名称 SAFETY SYRINGE
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tip to a final insertion state and release of an associated manual insertion load, the plunger tip may be proximally withdrawn, pulling the retractable needle proximally relative to the needle housing to a safe locked and retracted state wherein it is no longer exposed for injection.

主权项 1. A safety syringe system, comprising: a. an off-the-shelf syringe assembly comprising a syringe body forming a fluid reservoir and having proximal and distal ends and a plunger tip positioned within the fluid reservoir in a configuration such that medicinal fluid may be contained within the fluid reservoir; b. a needle assembly removably coupleable to the distal end of the syringe body such that the 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 c. 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tip to a final insertion state and release of an associated manual insertion load, the plunger tip may be proximally withdrawn, pulling the retractable needle proximally relative to the needle housing to a retracted state wherein a distal tip of the needle becomes mechanically locked into an encapsulated configuration wherein it is no longer exposed for injection.
