摘要:
A shieldable needle device (12) including a drive member (28, 30) is disclosed. The drive member is extendable between a biased position and an extended position for moving a tip guard (24) from an first position to a second position in which the tip guard shields a distal end (34) of a needle cannula 20). The shieldable needle device includes a pair of wings (66, 68) extending laterally from opposing sides of a hub (22) that are movable between a laterally extending position and a dorsal position. With the wings in the dorsal position a gap (150) is formed between the hub and the pair of wings, in said dorsal position the wings retain the drive member in the biased position thereby maintaining the tip guard in the first position. Movement of the wings from the dorsal position to the laterally extending position releases retainment of the drive member. A second drive member may be included.
