MULTI-VALVE MANIFOLD FOR DRUG INFUSION SYSTEMS

摘要

A multiple inlet manifold (20) for mixing and transporting therethrough flui ds under pressure comprising a manifold body including a plurality of valve inlets (25) and a single outlet (23), a mixin g chamber (32) provided between the valve inlets (25) and the outlet (23), and a flexible membrane (28) disposed between the valve inlets (25) and the outlet (23) to retain the valve inlets (25) normally closed at selected levels of fluid pressure. Fluid flow under pressure opens a valve inlet (25) to enable fluid flow in- to the mixing chamber (32).
