Rigid needle shield

摘要

A rigid needle shield for covering a distal end of a syringe is provided. The rigid needle shield includes an elongated flexible member connected to a sidewall of the rigid needle shield for moving the rigid needle shield between a first relaxed position and a second flexed position. When in the first relaxed position, the elongated flexible member is substantially within the rigid needle shield. However, when the elongated flexible member is moved to the second flexed position, the elongated flexible member extends beyond a proximal end of the rigid needle shield to engage a needle hub or a shoulder of the syringe to move the rigid needle shield distally relative to the syringe.

1. A rigid needle shield comprising:
an open proximal end; a closed distal end; a sidewall extending between the open proximal end and the closed distal end forming an elongated chamber therein; and an elongated flexible member having:
a first end connected to the rigid needle shield,a second end slidably connected to the needle shield proximate the open proximal end, anda middle portion extending between the first end and the second end and being deflectable to move the elongated flexible member between a first relaxed position and a second flexed position,wherein the middle portion is convex and bows outwardly from the sidewall when in the first relaxed position, and wherein the second end is within the elongated chamber in the first relaxed position and extends beyond the open proximal end in the second flexed position.
