Abstract:
1. A safety IV catheter assembly comprising: a catheter assembly including a catheter hub and a catheter tube, the catheter hub defining a cavity; a needle assembly including a needle hub and a needle, the needle having an enlarged diameter portion and a needle tip; and a needle guard assembly including a needle guard having a body portion including a proximal wall defining a guard bore and first and second legs extending distally from the proximal wall and defining a recess, at least one of the legs having a radially extending portion, the first and second legs being movable from an unguarded position wherein the needle is positioned between the first and second legs and a guarded position wherein the radially extending portion is positioned distally of the needle tip to obstruct distal movement of the needle, the needle guard assembly further including a bushing defining a bushing bore dimensioned to be slidably positioned about the needle within the recess at a location proximally of the enlarged diameter portion, an inner diameter of the bore of the bushing being smaller than the outer diameter of the enlarged diameter portion of the needle to prevent passage of the enlarged diameter portion of the needle through the bushing bore, wherein the outer diameter of the bushing is greater than the inner diameter of the guard bore to prevent withdrawal of the needle through the guard bore.
