    摘要： 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 inner bearing to obstruct the first interior space and prevent the inner bearing from retracting therethrough.

    摘要： A medical needle shield apparatus is provided that includes a needle hub having an outer needle cannula extending therefrom. An inner needle is disposed for slidable movement with the outer needle cannula. At least one shield is extensible from a retracted position to an extended position to enclose a distal end of the inner needle. The shield includes a binding member disposed within the shield and defines binding surfaces that form an aperture configured for slidable receipt of the inner needle. The binding member includes at least one drag inducing member that engages the inner needle during slidable receipt to create a drag force. The drag force facilitates rotation of the binding member such that the binding surfaces engage the inner needle to prevent slidable movement. The binding member further includes a needle communicating surface extending therefrom that is engageable with the inner needle to prevent rotation of the binding member. A retainer extends transversely from the needle communicating surface for releasable engagement with the needle hub.
