摘要:
The invention is directed to improved containers for pharmaceuticals and any tubing and tubing connectors associated therewith, particularly containers for pharmaceuticals which are irradiated, heated or otherwise subjected to increased pressure. In a preferred embodiment, the invention is directed to an improved container for use in a radioisotope generator, such as a rubidium-82 generator.

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.
