Abstract
An IV quick-connect/disconnect device is provided and generally comprises suitably molded single piece male and female connectors. The male connector has a male luer-lock on one end, one or more outwardly extending bayonet knobs on a middle portion and a reduced diameter second end which terminates in a resilient septum. The female connector has a female luer-lock on one end and a receiving cylinder with a bayonet cut out on the other; the luer-lock and the cylinder being separated by a wall through which a hollow needle extends that has been insert molded in the wall. The male and female connectors are mated by sliding the reduced diameter second end of the male connector into the receiving cylinder of the female connector, with the bayonet cutouts of the female connector serving as a track for the extended knobs of the male connector. The connectors are locked into place by bringing the male connector as far forward as possible, and then rotating the male connector such that extending knobs move past the restriction in the cutout and click (lock) into place.
