Abstract
Embodiments of the present invention utilize a closed-loop feedback control system to ensure accurate drug delivery. This control system may, for example, utilize a flow sensor to measure the volume of delivery and an intelligent control algorithm to anticipate and compensate for overdoses and underdoses. Feedback control systems in accordance herewith can be applied to any piston- or plunger-driven pump system utilizing sensors that measure flow directly or indirectly. In some embodiments, adjustments are made during a “priming” stage when liquid is pumped through the internal fluid path but does not exit the pump.
