Abstract
Fluid coupling devices are disclosed for use in receptacles such as receptacles on surgical aspiration equipment for selectively connecting a fluid conduit in the receptacle with a flow passage formed through a coupling device. The coupling devices in accordance with the invention comprise a spindle member which is non-rotatably held in the receptacle and a body member rotatably mounted on the spindle member for movement between an open position in which communication is established between the flow conduit in the receptacle and the flow passage in the coupling device, and a closed position disconnecting the conduit from the flow passage. The body member has a cam insert member with a through bore for connecting the flow conduit with the flow passage. The spindle member is formed with a cam surface for urging the cam insert member outwardly when it is moved into registration with the flow conduit in the receptacle so that an annular sealing lip on the outer surface of the cam insert member is compressed around the flow conduit to form an effective seal. In one embodiment of the invention the flow passage through the coupling device is formed through the body member and in another embodiment of the invention the flow passage through the coupling device is formed axially through the spindle member.
