Abstract:
A universal Luer coupling comprising:a body having a generally frustoconical male part having an axis and a first diameter and a second diameter smaller than said first diameter and axially spaced from said first diameter, said body terminating in an end adjacent said second diameter, said body having a pair of locking elements spaced radially from said male part and having inclined surfaces facing generally away from said second diameter and toward said first diameter;a female hub having an axis and an opening through one end of the hub for receiving said male part, said hub including a pair of flanges about said hub projecting outwardly therefrom at generally diametrically opposed sides of said hub, said hub being receivable about said male part with the smaller diameter of said male part disposed within said hub and the axes of said male part and said hub lying generally coincident with one another;said locking elements comprising a pair of substantially diametrically opposed, axially extending legs terminating in generally circumferentially extending flanges carrying said inclined surfaces, each flange of each said locking element having a distal end, the distal end of each flange of said locking element being spaced circumferentially from an adjacent axial extending leg of another of said locking elements a distance enabling a hub flange to pass therebetween upon said hub being receivable about said male part;said hub flanges engaging along said inclined surfaces and, in response to relative rotation of said hub and said male part in a first direction, causing said hub to advance toward said large diameter of said male part thereby to tightly engage said hub and said male part to one another.
