ABSTRACT:
A needle-less three part medical fluid flowline connector comprised of a relatively rotatable male Luer housing and a female Luer valve actuator includes a compressed elastomeric valve element having a fluid passageway therein which extends from an axially aligned end on one side of the valve element to an off-center positioned end on the other side of the valve element and avoids the use of a cannula and septum which is pierced during valve opening. Rotation of the compressible valve element with respect to the housing in which it is seated is prevented by interengaged fingers and grooves on the housing and valve element. Withdrawal of the valve actuator from the housing is prevented by a abutting radially extending surfaces and an annular bulge and groove on the actuator and housing respectively. An interengageable longitudinally extending finger and diametrically spaced grooves on the actuator and housing enable the user to readily position the valve in an open or closed position.
