Abstract

Systems and methods of controlling the flow of fluid from infusion pumps, such as pumps utilizing an electrokinetic engine, are discussed. In particular, a closed loop control technique can be utilized to regulate movement of a non-mechanically-driven moveable partition, which can be used to drive the flow of an infusion fluid. For example, one or more fluid shot amounts can be delivered by the infusion pump. One or more measured amounts can be determined for the fluid shot amount(s). An average measured amount can be calculated from the measured amounts, and a correction factor can be calculated using the average measured amount and an expected shot amount. Subsequently, a fluid shot amount can be delivered base upon the correction factor. Variations of this method, and systems for implementing the method, or portions thereof, are also discussed.
