Abstract:
1. Safety apparatus, comprising: a needle hub having a main body including a proximal portion and a distal portion, a needle extending from a distal end of said needle hub, said hub including a wall that extends orthogonally from the main body substantially at the junction where the proximal portion meets the distal portion; a collar having a proximal end rotatably mounted onto the distal portion of said needle hub so as to be rotatable about said needle hub, the wall at said hub providing a stop for the proximal end of said collar, said collar having a distal end and a second engage mechanism at the inner circumferential surface at the distal end; a housing pivotally connected to the proximal end of said collar; and a needle sheath having a proximal portion with a first engage mechanism at its outer circumferential surface, said first and second engage mechanisms fitted to each other when said sheath is fitted to the distal end of said collar, said proximal portion of said needle sheath being in contact engagement to said collar but not in contact with said needle hub for covering said needle extending from the distal end of said needle hub when said sheath is fitted to said collar and said first and second engage mechanisms are engaged to each other.
