  • Multi-chamber, sequential dose dispensing syringe
    Patent number: 7048720
    Abstract: A valve assembly is disclosed which partitions a conventional syringe into proximal and distal chambers to provide a multi-chamber, sequentially dispensing syringe apparatus. Incorporated in the valve assembly is a valved stopper having a valve (e.g. a slit valve) and a separator which filters out gas from liquid being dispensed through the valve assembly. A syringe plunger communicates through fluid in the proximal chamber to force displacement of the valve assembly. The valve is actuated by differential pressure of a force greater than the valve assembly displacement force. The valve assembly may be made from two parts: (1) a valved stopper (may be molded from basic syringe plunger material); (2) a separator (may be injection molded from syringe barrel material).
