Abstract
An IV infusion method and apparatus includes a plurality of fluid pumps mounted within a portable support housing and coupled to an IV tube. Each separate fluid pump is adapted to deliver fluid at a substantially constant delivery pressure predetermined by the characteristics of the pump. Each fluid pump includes an elastomeric membrane stretched into its region of nonlinear elasticity over a contour surface. Check valves located between the pumps and the IV tube control sequential dispensing of fluids from the pumps. The method and apparatus are especially adapted to a SASH process.
