Publication number: 20200100717Abstract: A shieldable needle device including a drive member is disclosed. The drive member is extendable between a biased position and an extended position for moving a tip guard from an first position to a second position in which the tip guard shields a distal end of the needle cannula. The shieldable needle device includes a pair of wings extending laterally from opposing sides of the hub that are movable between a laterally extending position and a dorsal position. With the wings in the 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.Type: ApplicationFiled: December 3, 2019Publication date: April 2, 2020Inventor: Bradley M. Wilkinson
