Abstract
A fluid supply system for gas and sterile liquids consisting of a disposable sterile cartridge that is connected to gas and liquid sources and a common exhaust. The cartridge cooperates with a rotating bearing assembly which pumps the liquid through the system without ever contacting the liquid. The gas sources are provided with means for supplying the gas under pressure to the cartridge. A suitable control selects either the gas or liquid source and a pair of gauges monitor the flow rates of the fluids.
