Summary:A shieldable needle device (12) with a needle cannula (28), a hub (44) supporting the needle cannula, and a tip guard (24) axially movable along the needle cannula where, upon transition, the tip guard protectively surrounds the distal end (42) of the needle cannula. The needle device includes a pair of wings (60) extending laterally from opposing sides of the tip guard and connected to the hub. The pair of wings are transitionable between a first position and a second position, wherein transition of the pair of wings advances the tip guard from a proximal position to a shielding distal position. The wings include protrusions (66) which cause the longitudinal axis of the needle cannula to become offset from the opening (52) of the tip guard during advancement of the tip guard preventing the needle cannula from being reinserted through the tip guard after the tip guard has been transitioned to the distal position.
