Abstract
Abstract The invention relates to a combination syringe and vial, each containing a separate chamber having an individual ingredient therein. The syringe and vial are assembled in interconnected relation to each other with the hub and cannula of the syringe extending within the vial in a manner to simultaneously support and seal the hub of the syringe with respect to a first closure in the vial and the distal portion of the cannula with respect to a second closure supported by the vial and in spaced-apart relation to the first closure, to maintain the respective chambers sealed off from each other. The first closure has a preformed axial bore extending entirely therethrough, and the second closure has a preformed axially extending channel therein. The dispensing of the ingredients occurs by displacing in a longitudinal direction the syringe and vial until the seal between the distal portion of the cannula and second closure is released, permitting movement of the plunger in the syringe to force the ingredient therein into the vial with resultant mixing of the two ingredients.
