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.

[ I claim:] [1.] A needle-less Luer actuated medical connector having a longitudinal axis, said connector comprising:A) a valve housing having a fluid flow passage therein aligned with said longitudinal axis, a valve seat therein, an open end for receiving a compressible valve element and a connection end for connecting said connector to a fluid flow line aligned with said longitudinal axis;B) a valve actuator having a fluid flow passage therein aligned with said longitudinal axis of said connector, a valve compressing end wall received in said open end of said housing, and a fluid flow passage extending through said end wall, said valve actuator being mounted in said open end of said housing for rotation about said longitudinal axis with respect to said housing;C) a resilient valve element compressed between said valve seat and said valve compressing end of said actuator, said valve element having a fluid passageway therethrough extending from an axially aligned opening on a first side of said valve element to an off-center positioned opening on an opposite side of said valve element; said off-center positioned opening of said fluid passageway in said valve element being aligned with one of (1) an off-center positioned end of said flow passageway in said valve actuator or (2) an off-center positioned end of said flow passageway in said housing when said actuator is rotated relative to said housing to open said valve and said off-center positioned end of said valve passageway being circumfrentially displaced from (1) said off-center positioned end of said flow passageway in said valve actuator or (2) said off-center positioned end of said flow passageway in said housing when said actuator is rotated relative to said housing to close the valve;D) means connecting said valve element to said housing to prevent relative rotation between said valve element and said housing;E) positioning means on said actuator and said housing to hold said actuator in either a valve open position or in a valve closed position relative to said housing; andF) restraining means on said housing and on said actuator for restraining relative axial movement therebetween while permitting relative rotation therebetween.
