Abstract
A needle safety apparatus is disclosed which includes an inner bearing disposed within an outer bearing. The inner bearing is moveable to extend telescopically in a first interior space defined by the outer bearing. A second interior space is defined by the inner bearing, while extendable linkage segments connect the hub to the inner bearing. A hub retains the proximal end of a needle, while the distal end of the needle extends through the second interior space. A wedging portion is movable with the inner bearing and pivots to secure the distal end of the needle within the second interior space when the distal end of the needle is retracted therethrough. A latch may be formed in the outer bearing to obstruct the first interior space and prevent the inner bearing from retracting therethrough.
