ABSTRACT:
A needle shield comprising an elongated tubular housing having a central bore, means at one end for detachably mounting the shield to the hub of a syringe assembly, and means defining an elongated generally cylindrical chamber in the end of the housing opposite the mounting means. An inner end communicates with the bore and an insert made of resilient impermeable pierceable material is snugly supported in the chamber. The chamber is of a diameter slightly greater than the diameter of the insert and includes a tapered wall portion at the inner end and has a section of smaller diameter than the insert to provide a tight generally hermetic sealing relation therewith. The wall of the chamber opposite the inner end is deformable to permit ease of assembly and deformation after insertion of the plug to firmly seat the plug in the chamber. The needle shield also includes a series of relief grooves in the exterior surface portion of the base of the housing which comprises the hub mounting portion to provide a degree of flexibility and ensure secure mounting even during expansion in autoclaving. The hub portion of the housing is also provided with a series of radially inwardly directed beads and ribs to provide sealing means between the hub of the needle shield and the needle hub.
