Claim Text:
1. A safety needle assembly comprising: a hub; a needle fixed to said hub, said needle having a distal end, formed for insertion into a patient, and a proximal end; a shield; a tab; a spring disposed between said shield and said hub configured to bias said shield distally relative to said hub; and a clip disposed between said hub and said shield, said clip having a notch formed thereon shaped to permit passage therethrough of said tab, wherein said clip is axially fixed relative to one of said hub or said shield and is rotatable with respect to said one of said hub or shield that said clip is axially fixed relative to; wherein said clip and said tab are engaged to form a first locked state and releasably retain said shield in the first locked state against the biasing force of said spring wherein the interengagement of the clip and the tab limits distal movement of said shield relative to said hub; wherein in said first locked state: said shield is movable proximally relative to said hub; and said notch is spaced from said tab; wherein said clip and said tab are relatively displaceable to align said notch with said tab and release said shield from said first locked state, thereby allowing said shield to move distally, relative to said hub, to a second shielded state; and wherein, in said second shielded state, said distal end of said needle is covered by said shield.
