<p>A stoppered drug vial forms part of a drug delivery system which maintains the sterility of the drug in storage, dilution and use. A removable, pierceable diaphragram is placed over the stopper which seals the vial. The removable, pierceable diaphragm is held in place by attachment to a skirt member which encloses and is in frictional contact with the upper portion of the vial wall. Access to the drug in the vial may be obtained by either removing the diaphragm and the stopper or piercing the diaphragm and the stopper with a cannula.</p> |
