摘要:
A safety needle assembly is provided herein having a hub; a needle fixed to the hub; a shield; a tab; a spring disposed between the shield and the hub configured to bias the shield distally; and, a clip disposed between the hub and the shield, the clip having a notch formed thereon shaped to permit passage therethrough of the tab. The clip and the tab releasably retain the shield in a first locked state against the biasing force of the spring thereby limiting distal movement of the shield relative to the hub; yet, in the first locked state, the shield is movable proximally relative to the hub. In the first locked state, the notch is spaced from the tab. The clip and the tab are relatively displaceable so as to align the notch with the tab and release the shield from the first locked state thereby allowing the shield to move distally, relative to the hub, to a second shielded state. In the second shielded state, the distal end of the needle is covered by the shield. Advantageously, with the subject invention, a passive safety needle assembly may be provided which requires few parts and is reliable.
