Abstract:
1. A medical needle shield apparatus comprising: a needle hub; a needle disposed within said needle hub; said needle hub having a lumen and a magnifier section for viewing fluid flashback exiting said needle through the lumen, the lumen including a reduced constant diameter at the magnifier section and an increased diameter outside of the magnifier section; at least one shield being extensible from a retracted position to an extended position to enclose a distal end of said needle; and a binding member disposed within said at least one shield and defining binding surfaces that form an aperture configured for slidable receipt of the needle between the retracted position and the extended position, wherein the binding surfaces are configured to rotate in the same direction into a binding position such that the binding surfaces engage the needle to prevent slidable movement of the at least one shield in the extended position and wherein the binding member includes a drag inducing member that generates a drag force that facilitates rotation of the binding surfaces into the binding position.
