ABSTRACT:
A flexible container for medical fluid including a flexible housing with an adapter secured to the housing for connecting an outlet to a complementary inlet of another container sealed by a stopper having an outlet connected to an inlet and disposed to serve as a conduit for fluid flow, with a movable member sealing the inlet and having a flexible body for controlling flow by the extent to which the flexible body is buckled and the removal of flex restores the seal; the stopper can take the form of a flow control device with an inlet for fluid and a slotted movable member sealing the inlet and closing the slot, with the unsealing of the inlet and the opening of the slot permitting the passage of fluid to an outlet, advantageously through a cannula that is surrounded by the opened slot and extends to the outlet; 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 allow the flow of fluid.
