<p>A device (20) for the removal and replacement of a needle shield (21) having distal end (22), an open proximal end (23) and a side wall (25) therebetween having an outside surface (27) includes a housing (28) having a proximal end (29) and a distal end (31). The housing includes a bore (32) therein beginning at the proximal end. A threaded portion (33) is provided in the housing along the bore and accessible through the bore. The threaded structure is spaced from the proximal end of the housing and is capable of engaging and holding the outside surface of a needle shield which is placed into the bore through the proximal end of the housing and rotated in a direction to advance the needle shield distally along the threaded structure. <IMAGE></p> |
