Abstract: Provided is a system for dispensing fluid. The system includes a housing defining a chamber; an inflatable bag disposed in the chamber and adapted to contain a fluid, the bag being in fluid communication with a flow path for flow of the fluid out of the bag; and a pressure source for inflating the bag to force the fluid from the bag to the flow path at a controlled rate. The bag inflates against an inner surface of the housing such that, prior to the bag being fully inflated, the fluid contained in the bag is forced from the bag at the controlled rate.

Abstract: The present invention includes methods and apparatuses for operating and controlling AOD pumps (10, 10?, 10?, 100, 460, 580, 740) and other pumps.

Abstract: The present disclosure provides a spring controlled valve including a spring being movable between an expanded position wherein coils of the spring are spaced apart from one another thereby permitting gas flow through the valve and a compressed position wherein the coils are in contact with one another thereby substantially preventing gas flow through the valve.
