CAPACITOR DETECTION FOR IV PUMP TUBE CALIBRATION

WIPO Patent Application WO/2020/012419

A3

A system and method for calibrating an IV pump infusion system tube comprises a fluid source, an infusion system comprising, an IV pump, a drive unit, a chamber with known constant volume, a control unit, and IV tubing with a known inner diameter tolerance, and a set of conductive plates. The system administers medicinal fluid, calculates the flow rate of the medicinal fluid in the chamber by measuring the time the capacitance level of the medicinal fluid changes from a capacitance level corresponding to a first (initial) position to a capacitance level corresponding to a second (filled) position, compares the calculated flow rate with a set flow rate of the IV pump input in the control unit prior to infusion, and adjusts the IV pump and flow rate based on the compared deviations for more accurate delivery to a patient. This configuration may therefore provide a more precise delivery rate.
