Patent

CA 2676248

A displaceable valved stopper is disclosed which partitions a conventional syringe into proximal and distal chambers to provide a multi-chamber, mixing syringe assembly. Also the valved stopper and a valve assembly are disclosed for use in a single conventional syringe to provide dual chamber mixing plus a disparate and sequentially dispensed flush. Incorporated in the valve assembly is another valved stopper and a separator which filters out gas from liquid being dispensed through the valve assembly. A syringe plunger communicates through fluid in a more proximal chamber to force displacement of the valved stopper and valve assembly for both mixing and dispensing.

L'invention concerne un dispositif d'arrêt à soupape déplaçable séparant une seringue classique en chambres proximale et distale pour fournir un ensemble de seringue de mélange à multiples chambres. En outre, le dispositif d'arrêt à soupape et un ensemble de soupape sont décrits pour une utilisation dans une seringue classique unique pour fournir un mélange à deux chambres plus un rinçage disparate et distribué de façon séquentielle. Incorporé dans l'ensemble de soupape se trouve un autre dispositif d'arrêt à soupape et un séparateur filtrant le gaz à partir d'un liquide distribué à travers l'ensemble de soupape. Un piston de seringue communique à travers le fluide dans une chambre plus proximale pour forcer le déplacement de l'ensemble dispositif d'arrêt à soupape et soupape à la fois pour le mélange et la distribution.
