Patent ID: 8133207

Claim:
A device comprising: a needle cannula having proximal and distal ends; a hub supporting said proximal end of said needle cannula; a pair of wings extending laterally from the hub, said wings being bendable between a laterally extending position and a dorsal position; a shield axially movable along said needle cannula from a proximal position to a distal position; and a drive member extendable between a biased position and an extended position for moving said shield from said proximal position to said distal position, wherein said drive member is connected to said hub and connected to said shield, wherein said pair of wings retains said drive member in said biased position when in said dorsal position, thereby maintaining the shield in the proximal position, and wherein movement of said wings from said dorsal position toward said laterally extending position enables the wings to release said drive member and thereby enable the shield to extend from the proximal position toward the distal position.
