  • Patent number: 5304163
    Abstract: The device of the present invention includes a flexible container having an administration port and a flexible tube extending therefrom. The administration port includes an access membrane through which a spiked cannula can be inserted to gain access to the interior of the flexible container. The flexible tube contains a frangible or breakaway valve therein. Permanently secured to the end of the flexible tube is a sheath having a substantially circular base and an open-ended skirt including an inner surface depending from the base. The skirt includes a plurality of inwardly projecting bumps intermittently spaced around the inner surface to sealingly engage a standard drug vial. A sharp cannula is mounted within the skirt to pierce the stopper of the standard drug vial to establish fluid communication between the cannula and the interior of the drug vial. A peelable closure is provided covering the skirt opening prior to use to maintain a sterile condition of the device.
