Abstract: A syringe needle shield (10) and a method of using the syringe needle shield (10) that is configured to enclose a needle el (4) of a syringe (2), the syringe needle shield (10) comprising a proximal end (20) providing access to an inner cavity (50), a distal end (22) including a flange (30), and an outer surface (24) including a plurality of ribs (40) disposed adjacent to the flange (30), each of the plurality of ribs (40) including a substantially flat surface (42) and a concave surface (44), wherein the substantially flat surface (42) is adjacent to the concave surface (44).

Abstract: A syringe assembly includes a syringe barrel (12) having a proximal end and a distal end, a needle hub (20) supporting the needle and coupled to the distal end of the syringe barrel (12). A connecting member (46, 102, 156) is positioned on the syringe barrel for sliding between a first position where the needle is exposed and a second position covering at least a portion of the needle. The connecting member (46, 102, 156) is configured for connecting to a container (50) and supporting the container when said needle is advanced to pierce a septum (90) in said container. In another embodiment, a syringe assembly includes a syringe barrel and an adapter (222, 282, 322) coupled to the distal end of the syringe barrel (12). The adapter (222, 282, 322) is movable between a first position to expose a first portion of the needle (22) having a first length, and a second position to cover the distal end of the syringe barrel to expose a second portion of the needle having a second length.
