Abstract
An infusion pump is disclosed in which a canister of compressed gas is regulated to provide a continuous source of pressure to one or more compressible fluid sources. Valves on the outlets of the sources prevent fluid from escaping except when the valves are opened. The valves are opened by solenoids which are selectively activated to open the valves.
