Abstract

The fluid transfer device of the present invention is used for example, to provide access to a vacuum tube which is sealed with a stopper. The device has a cylindrical body with a top wall portion and first and second conduits fixed and extending therethrough. The first, or pouring conduit, and second, or pressure equilibrating conduit, extend generally in a parallel manner above and below the top wall portion, and their respective bottom portions are contained within the body of the hollow device. The pair of conduits are constructed and arranged within the body of the device to pierce and enter through the stopper of the sealed container to permit the delivery of fluid. Further, the device has a structure that can be easily and economically manufactured for disposable use.
