Patent ID: 8777931

Claim:
A retractable luer lock system comprising: a male tubing fitting extending along a longitudinal axis and having a first internal bore and an end portion including a male plug, wherein the male tubing fitting comprises a plurality of flanges at the distal end thereof; a female tubing fitting having a second internal bore configured to receive the male plug; and a collar disposed about the male tubing fitting and positioned to slide freely along the longitudinal axis from a first position to a second position, wherein in the first position the male and female tubing fittings are unlocked with respect to each other such that the male plug is removably insertable into the second internal bore of the female tubing fitting and in the second position the male and female fittings are locked with respect to each other such that the male plug is prevented from being removed from the second internal bore of the female tubing fitting; wherein the collar includes an elastically deformable portion that deforms in order to slidably position the collar along the longitudinal axis from the first position to the second position, wherein the male tubing fitting includes a retention member that selectively retains the collar in the first position; wherein the elastically deformable portion includes a tapered lip, the tapered lip interfacing with the retention member to selectively retain the collar in the first position; wherein the elastically deformable portion includes slits that interrupt the tapered lip thereby allowing the tapered lip to deform outwardly from the longitudinal axis to slide the collar beyond the selective retainment of the retention member; and wherein an entire internal diameter of the tapered lip prevents the collar from moving over the plurality of flanges.
