1. A needle shield assembly for use with a needle assembly including a needle cannula having a proximal end, a distal end and a lumen therethrough, and a hub having an outer surface further comprising a plurality of radial projections and a plurality of hub splines extending radially from the hub, an open proximal end spaced from the radial projections and the hub splines including a cavity therein and a distal end attached to the proximal end of the needle cannula so that the lumen is in fluid communication with the cavity, the needle shield assembly comprising:
an elongate needle shield comprising a shield portion, a hub connection portion and a bridge portion including a living hinge having a thickness, the bridge portion joining the hub connection portion and the shield portion, the hub connection portion comprising a receiving ring having a diameter sized to frictionally receive the hub outer surface when the needle assembly is inserted through the receiving ring and a flange extending from the receiving ring defining a top planar surface and a bottom surface, the hub being rotatable within the receiving ring, a cylindrical wall extension having an inner surface with splines that are configured to cooperate with hub splines on a needle hub when a needle hub is engaged with the cylindrical wall extension, wherein the hub splines and the splines are configured to create a tactile or perceptible click during each rotation as the hub splines and the splines engage and disengage each other as the hub is rotated with respect to the shield portion, the shield portion having two side walls defining a longitudinal opening and a back wall between the side walls defining a recess having an interior surface, the shield portion configured to pivot from an open position in which the needle cannula is exposed, to a closed needle protecting position in which the distal end of the needle cannula is within the longitudinal opening of the shield.
