Abstract:
1. A method of manufacturing a safety syringe, comprising the steps of: a) molding a one piece syringe having a syringe barrel, a needle hub extending from a distal portion of said syringe barrel, a circumferential wall that forms a distal end that is a part of said distal portion surrounding at least one portion of said needle hub so that an annular space extending away from the syringe barrel into open space separates said distal end and said needle hub, and a collar reception mechanism at the distal portion of said syringe barrel proximate to said distal end; b) mounting a needle from said needle hub; c) providing a collar having pivotably attached thereto a needle protection housing; and d) mating said collar to said collar reception mechanism by press fitting said collar past said distal end of said syringe barrel; wherein said annular space enables said distal end to compress toward said needle hub to facilitate the mating of said collar to said collar reception mechanism; and wherein said housing is pivotable to a position along the longitudinal axis of said syringe for covering said needle mounted from said needle hub of said syringe.
