Patent ID: 7837659

Claim:
A needle assembly comprising a male luer fitting having an exterior side wall extending from a distal end to a proximal end; a female luer fitting having a body including an outside surface, a distal end, a proximal end and a passageway therethrough, the passageway having a frusto-conically shaped portion with an interior surface and a diameter for receiving the male luer fitting, the interior surface having a recess; a cannula connected to the distal end of the body of the female luer fitting the cannula being in fluid communication with the passageway; and a soft, resilient member positioned in the recess and bounding the passageway, wherein the diameter of passageway is smaller where it is bounded by the soft, resilient member and the soft resilient member forms an engagement surface such that, upon insertion of the male luer fitting into the passageway, the soft, resilient member surrounds the exterior side wall of the male luer fitting and the soft, resilient member and a portion of the interior surface of the passageway distal to the soft, resilient member both frictionally engage the exterior side wall of the male luer fitting; the body of the female luer fitting having at least one channel extending from the recess to the outer surface, the soft, resilient member extending into the channel; wherein the soft, resilient member is softer than the body of the female luer fitting.
