    摘要: A twist valve for use in a fluid delivery system is provided for selectively allowing fluid flow and blocking fluid flow therethrough. The twist valve is in communication with a pre-filled flexible container and includes a proximal part and a distal part each having a fluid inlet and a fluid outlet. The proximal and distal parts are equipped with cylindrical helical surfaces which allow them to move toward or away from each other when a twisting force is applied to them. The fluid outlet of the proximal part is blocked with a stopper in the distal part when the twist valve is in the closed position, and is unblocked by the stopper when the twist valve is in the open position.
