Abstract
An IV fluid delivery system for use in connection with a resilient, deformable tube, wherein pinching fingers occlude the tube and pumping fingers deform the tube (without occluding it) against a first pressure pad or support means in a pumping action, while restoring fingers urge the tube against a second pressure pad or support means to restore its cross-sectional shape, so as to improve the accuracy, consistency, and predictability of flow through the tube.
