ABSTRACT:
A flow control device with an inlet for fluid and a slit movable member having an oval shape before sealing the inlet at a cam interface and closing the slit. The unsealing of the inlet and the opening of the slit permits the passage of fluid therethrough. The movable member extends by a channel, which can be open or closed, between the inlet and an outlet and has a portion which is expandable laterally. A member external to the flow control device, such as the tip of a Luer taper, can activate the moveable member by depressing it to open the slit and allow the flow of fluid.
