A shieldable needle device (12) including a first drive member (28) and a second drive member (30) is disclosed. The two drive members 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 retainer member (26) supporting the proximal end of the needle cannula, the retainer member being movable between an open position and a retaining position. The retainer member retains the first drive member and the second drive member in the biased position thereby maintaining the tip guard in the first position, and movement of the retainer member from the retaining position to the open position releases retainment of the first drive member and the second drive member thereby allowing the first drive member and the second drive member to transition to the extended position and move the tip guard from the first position to the second position.
