Abstract：To solve the problems of low efficiency, low detection accuracy, temperature deviation and data batch processing in the manual calibration process of medical infusion pump, an infusion pump automatic calibration scheme based on indirect flow method was proposed. The volume of the specific glass tube segment was calibrated through experiments to obtain the cumulative flow volume, and the accumulative time was obtained by measuring the time of filling the calibrated volume when the infusion pump was automatically calibrated. Thus a dual-channel medical infusion pump automatic calibration system was designed, which can perform error and repeatability analysis and uncertainty evaluation of the measurement results and give a calibration report. The verification experiment shows that the relative error of the automatic calibration system can reach less than 2%, meeting the requirements of 5% of the relevant specifications. The system can repeatedly measure the accuracy of the same infusion pump at different flow rates, which can also use dual channels to simultaneously perform flow calibration tests on multiple infusion pumps, as well as to calibrate the blocking alarm condition of the infusion pump.
