A shieldable needle device comprising: a needle cannula having a proximal end and a distal end ; a retainer member supporting the proximal end of the needle cannula, the retainer member movable between an open position and a retaining position; a tip guard axially movable with respect to the needle cannula from a first position adjacent the retainer member to a second position in which the tip guard shields the distal _end of the needle cannula ; a first drive member extendable between a biased position and an extended position for moving the tip guard from the first position to the second position, the first drive member having a proximal end connected to the retainer member and a distal end connected to the tip guard ; and a second drive member extendable between a biased position and an extended position for moving the tip guard from the first position to the second position, the second drive member having a proximal end connected to the retainer member and a distal end connected to the tip guard, wherein, with the retainer member in the 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, and characterized by , when the first drive member and the second drive member are each in the extended position, the first drive member , the second drive member , and the tip guard completely surround and shield the needle cannula . a needle cannula having a proximal end and a distal end ; a retainer member supporting the proximal end of the needle cannula, the retainer member movable between an open position and a retaining position; a tip guard axially movable with respect to the needle cannula from a first position adjacent the retainer member to a second position in which the tip guard shields the distal _end of the needle cannula ; a first drive member extendable between a biased position and an extended position for moving the tip guard from the first position to the second position, the first drive member having a proximal end connected to the retainer member and a distal end connected to the tip guard ; and a second drive member extendable between a biased position and an extended position for moving the tip guard from the first position to the second position, the second drive member having a proximal end connected to the retainer member and a distal end connected to the tip guard, wherein, with the retainer member in the 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, and characterized by , when the first drive member and the second drive member are each in the extended position, the first drive member , the second drive member , and the tip guard completely surround and shield the needle cannula . <EOS>
