ABSTRACT:
A shielded needle assembly has an elongate needle with a proximal end, a distal end and a passageway therethrough. The assembly has a needle hub that has a proximal end, a distal end and an outside surface with an axial opening therethrough to receive and hold the needle with the distal end of the needle projecting distally axially. The assembly also has an elongate shield with a proximal end, a distal end and a sidewall with an elongate opening from its distal end to its proximal end. At least a section of the shield is substantially cylindrical and has an exterior surface. The shield is operable between an open position, where the needle is exposed for use by passage through the elongate opening, a closed position, where the shield substantially obstructs access to the needle, and a latched position, where the elongate opening is substantially obstructed and the shield is prevented from inadvertent movement to the open position. The assembly has a latch with an outwardly extending tab and a visual indication when the elongate opening is substantially obstructed. The assembly has a hinge including a mount for retaining the shield onto the needle hub. The shield is movable between the open position and the closed position over the needle by an off-axis pivotal movement about the hinge. The shield is latched and unlatched when in the closed position by a rotational movement of the latch with respect to the shield.
