The present invention provides an apparatus for introducing a reconstituted drug in a drug vial into a medical liquid while venting any gas within the vial to the atmosphere. The assembly includes a receptacle disposed in the middle of a fluid conduit for the medical fluid and which has an upper chamber and lower chamber. The assembly also has a cannula assembly which mounts upon and pierces a septum of the receptacle and also a pierceable stopper of the drug vial. The cannula assembly includes a pair of coaxial cannulas which pierce the stopper of the drug vial and establish a first flow path from the upper chamber to the drug vial and a second flow path from the drug vial to the lower chamber. The cannula assemble also includes a cannula that forms a vent passage in fluid communication with an upper portion of the vial, upon the piercing of the drug vial, with an end of the vent passage communicating with the atmosphere.

[ What is claimed is:] [1.] An apparatus for the delivery of a passively reconstituted beneficial agent contained in a vial into a medical liquid, comprising:first flow path adapted to introduce into the vial the medical liquid from a fluid conduit, the first flow path including an upper chamber of a receptacle disposed in the fluid conduit and an annular space coaxially extending from the upper chamber to an upper part of the vial at around a lower cannula hollow tube which is formed at the lower part of a cannula assembly along the central axis thereof, the cannula assembly extending from the bottom of the vial to a lower chamber of the receptacle when the cannula assembly has piercingly and sealingly been mounted on the receptacle for use;second flow path adapted to deliver the mixed solution containing the medical liquid and agent from the vial into the fluid conduit, the second flow path including the lower cannula hollow tube extending from an upper part of the vial to the receptacle lower chamber and the lower chamber; andvent passage means for the communication of the vial with the atmosphere, the vent passage including an upper cannula hollow tube which is formed at an upper part of the cannula assembly along the central axis thereof, and which extends from the bottom of the vial to the lower cannula hollow tube, a side cannula tube extending parallel to the lower hollow tube from an end part of the upper cannula hollow tube to a small chamber, which has a vent hole to the atmosphere, and which is intermittently disposed between the vial and the upper chamber, a hollow tube connecting the upper hollow tube and the side hollow tube, and the small chamber.
