SAFETY SYRINGE

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.

1. A safety syringe system, comprising:
a. a syringe body forming a fluid reservoir and having proximal and distal ends; b. a plunger tip positioned within the fluid reservoir in a configuration such that medicinal fluid may be contained within the fluid reservoir; c. 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 d. 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.
