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 the needle assembly comprises a needle housing member removably coupled to the retractable needle and also removably coupled to a needle cover, the needle cover providing a relatively large geometric guiding surface for aligning a proximal end of the retractable needle as it is guided into fluidic contact with the fluid reservoir of the syringe body.
