SYRINGE SYSTEM ACCOMMODATING SEPARATE PREFILLED BARRELS FOR TWO CONSTITUENTS

摘要

A prefilled, two-constituent system is provided with first and second containers or barrels. The first barrel includes a first chamber having a dispensing end or delivery en d. The delivery end defines a dispensing passage or delivery passage communicating through the delivery end to accommodate the dispensing of fluid from the first chamber. A movable seal or reciprocab le stopper is slidably disposed in the first chamber, and a first constituent is provided in the first chamber between the delivery end and the stopper. A second container or barrel is sized to be disposed in the first barrel and has a discharge end defining a discharge passage communicating through t he discharge end to accommodate the discharge of fluid from the second barrel. A plunger is slidably disposed within the second barrel. A liquid second constituent is provided in the second barrel between the discharge end and the plunger. The first barrel stopper and the second barrel discharg e end are engageable directly or indirectly to cooperatively define a coupling accommodating the flow of the liquid second constituent from the second barrel into the first chamber of the first barre l as the second barrel moves outwardly relative to the first chamber.
