ABSTRACT:
A shieldable needle device is provided. The shieldable needle device includes a housing, a needle cannula, a tip guard and a flexibly resilient drive mechanism. The housing includes a first lateral extension and a second lateral extension which are interconnected at a rearward end to form a hub portion from which the needle cannula extends. The tip guard telescopes over the needle cannula from a retracted position to an extended position. The drive mechanism is attached to the tip guard and is bent or coiled within the housing between the first and second lateral extension and retained in the bent or coiled position. Upon release of the drive mechanism, the tip guard is moved from a retracted position to an extended position, thereby protectively surrounding a tip of the needle cannula.
