Dual chamber internal by-pass syringe assembly |
摘要 |
<p>A syringe assembly comprising an elongated hollow tubular barrel having a discharge opening at one end and a radially inwardly directed circumferentially extending rib in the inner peripheral surface of said barrel divides the barrel into a first medicament chamber on one side of said rib and a second diluent chamber on the opposite side of said rib. A by-pass stopper engages interiorly of the barrel and has a circumferentially extending exterior sealing surface of a predetermined diameter greater then the diameter of the rib to provide a seal between the chambers when engaged therewith. The by-pass stopper has at least one axially extending flow path on at least one side of the sealing surface providing fluid communication between the chambers when the by-pass stopper is displaced axially relative to the rib and the rib is aligned with the flow passage way.</p> |
