Abstract
An infuser apparatus for the delivery of fluid at accurate and controlled rates of flow comprising a housing, a deformable member, inlet means and outlet means. Fluid is introduced through the inlet means forcing the deformable member to bend away from its normal position and to generate a pressure force against the fluid introduced. When the outlet means is opened, the fluid is expelled by means of the deformable member returning to its normal position. The infuser apparatus may expel the fluid at either a constant or at a varied and controlled rate depending on the configuration of the deformable member. Further, multiple infusers may be coupled together in a fluid delivery system.
