ABSTRACT:
A needle protection assembly has a needle hub with a proximal portion having two sets of spaced flanges and a distal portion having a number of arms for forming at least one catch and one slot. A collar with a needle protection housing has at its inner surface a number of protrusions fittable within the space defined by the two sets of flanges, when the collar is press-fitted to the needle hub, and a number of fingers that removably grasp a needle sheath that covers the needle extending from the needle hub. After the sheath is removed, the needle protection housing may be pivoted to cover the needle. Once the housing fully covers the needle, a spline inside the housing coacts against the catch at the needle hub to enable the needle hub to be removed from a syringe by rotating the housing.
