Abstract
A flow control device has an inlet, an outlet and a conduit connecting the inlet to the outlet enabling fluid flow from the inlet to the outlet. A movable head with a slot therethrough seals the inlet. The head is connected to elongated legs which are flexed when the head is moved out of the inlet, opening the slot, providing a return force for returning the head to its position sealing the inlet. Preferably, the slot is normally open and the inlet closes the slot when the head is in the inlet. Movement of the head out of the inlet opens the slot, permitting the passage of fluid through the head. A spring can bias the head toward the inlet, instead of the elongated legs. A member external to the flow control device, such as the tip of a Luer taper, can open the slot by depressing the head, allowing the flow of fluid through the device.
