Abstract
A safety needle assembly has a needle hub and a needle cannula projecting from the hub. Wings project transversely from the hub to facilitate manipulation and positioning of the needle assembly. A shield is hingedly attached to the needle hub and can be rotated from a first position where the needle cannula is exposed to a second position where the needle cannula is shielded. At least one latch may be disposed on the shield for secure locked engagement with the hub, the wings and/or the tubing extending from the hub. A spring may also be provided for propelling the shield into the second position.
