ABSTRACT:
A shielded needle assembly includes an elongate needle having a pointed distal end, a proximal end and a passageway therethrough. The assembly further includes a hub having an opening for receiving the needle so that said distal end of said needle projects outwardly, and has elements for releasably mounting the hub on a fluid handling device. The assembly has a shield having an open end, a closed end, a sidewall having a slot extending from the open end toward the closed end, and an arm extending radially outwardly at the open end opposite the slot. The shield has a first position at which the needle is exposed for use and a second position at which the shield substantially obstructs access to the needle. The slot provides clearance for the needle. A mounting rotatably holds the shield onto the hub. The mounting has a first pivot for pivotally attaching the shield to the mounting at the arm. The mounting further includes a second pivot having activating elements pivotally attached for interacting with the arm so that movement of the activating elements about the second pivot by the user causes movement of the shield from the first position toward the second position.
