ABSTRACT:
The present invention is directed to a shieldable needle device. The shieldable needle device includes a housing, a needle cannula, a tip guard and an elongated flexibly resilient drive mechanism. The housing includes a longitudinal slot that extends along a wall of the housing. The drive mechanism is bent within the housing and includes a first end which extends through the longitudinal slot and a second end which is anchored to the tip guard. Upon movement of the first end along the longitudinal slot, the second end extends and moves the tip guard from a retracted position to an extended position thereby protectively surrounding a tip of the needle cannula.
