A needle shield assembly of the present invention includes a needle cannula having a proximal end, a distal end and a lumen therethrough. A hub having a proximal end for connecting to a medical instrument and a distal end connected to the proximal end of the needle cannula is provided. A base member is connected to the hub. An elongate needle shield includes a proximal end hingedly connected to the base member, a distal end and a longitudinal axis therebetween. The needle shield includes a longitudinal opening therein. The needle shield is capable of rotating from a first position exposing at least the distal end of the needle cannula and a second position wherein the needle cannula is within the longitudinal opening of the needle shield. A sleeve having a longitudinal slot is rotatably connected to the needle shield. The sleeve is capable of rotating about the needle shield to an open position where the longitudinal slot in the sleeve and the longitudinal opening in the needle shield are sufficiently aligned to allow passage of the needle cannula so that the needle shield can be rotated from the first position to the second position. The sleeve is rotatable about the needle shield, to a position which blocks the longitudinal opening of the needle shield. Color safety indicator means for visually indicating the sleeve is rotated to a position which blocks the longitudinal opening of the needle shield is provided. <IMAGE> |
