Abstract
The present invention is directed to a shieldable blood collection set and a needle assembly. The needle assembly includes a needle cannula having a puncture tip at a distal end, and a needle retraction mechanism including a hub portion at a proximal end which supports the needle cannula, a shield portion at a distal end, and an extendable member hingedly connected therebetween. The hub portion includes a lateral hub extension extending toward a distal end of the needle cannula, and the shield portion includes a lateral shield extension extending toward a proximal end of said needle cannula. Opposing lateral forces applied against the extendable member and an opposing lateral side of the needle retraction mechanism cause relative axial movement between the hub portion and the shield portion between a first sampling state with the puncture exposed, and a second shielded state with the puncture tip contained within the shield portion.
