NEEDLE SHIELD ASSEMBLY HAVING A SINGLE-USE CANNULA LOCK

摘要

A needle shield assembly having a single-use cannula lock of the present inventi on includes a needle cannula having a proximal end, a distal end and a lumen theret hrough. A hub includes a proximal end for connection to a fluid transfer device and a dist al end connected to the proximal end of the needle cannula. A collar is rotationally c onnected to the hub so that the collar can be rotated around the hub. An elongate needle cov er removably engages the hub and covers the needle cannula. An elongate needle shi eld having a proximal end and a distal end is hingedly connected, through its proxim al end, to the collar. The needle shield includes two sidewalls defining a longitudinal ope ning and a back wall between said side walls defining a recess having an interior surface. The needle shield is capable of pivoting from an open position wherein the needle cannula i s exposed, to a closed needle protecting position wherein at least part of the needle cannu la is within the longitudinal opening of the needle shield. The needle shield assembly furthe r includes structure for preventing the needle shield from pivoting into the closed positio n unless the needle cover is removed, and structure for locking the needle shield in the clos ed needle protecting position when the needle shield is pivoted into the closed position T he structure for locking traps the needle cannula in the longitudinal opening of the needle s hield.
