Patent ID: 8628497

Claim:
A needle assembly comprising: a needle tip guard comprising: a proximal base defining an opening dimensioned for passage of a needle therethrough; first and second clamp members extending from the proximal base and defining an internal cavity, each of the first and second clamp members having an inner surface including a protrusion extending into the internal cavity and a distal end supporting a clamp arm, the clamp arms being supported for movement between an open position and a closed position; and a finger tab extending from the proximal base and including a contacting portion for engagement by a user; and a needle dimensioned for insertion through the proximal base and clamp members, the needle having a needle cannula including a distal portion having at least one indentation dimensioned to receive the protrusion of the clamp members, the needle cannula of the needle being positionable between the clamp members to retain the clamp arms in the open position, whereby receipt of the protrusions within the at least one indentation of the needle upon retraction of the distal portion of the needle within the internal cavity of the clamp members allows the clamp arms to move to the closed position.
