ABSTRACT:
An adapter has a cannula to deliver a drug to the interior of a vial. The vial contains a plunger that has a penetratable self-sealing rubber diaphragm, as is common. The adapter comprises a barrel adapted to fit over and telescope onto the vial, with a cannula rigidly mounted axially in the barrel and long enough to reach the bottom of the vial after penetrating the rubber diaphragm. The barrel incorporates fins that stabilize the cannula axially. Cover plugs are provided to close both the barrel and the vial before use. When the covers are removed and the barrel s fitted down over the vial, the cannula projects beyond the fins to penetrate the plunger and push the plunger to the bottom of the vial. The long barrel and the rigidly maintained cannula insure that the cannula cannot contact the inner wall of the vial.
