Abstract Using the principle of measuring the micro-flow rate of a fixed-volume piston cavity, based on the relationship between the piston displacement and the flow rate, the measurement model, theoretical calculation method, hardware design and corresponding software system of medical micro-flow are introduced. The micro-flow measurement technology can complete the calibration of medical infusion pump and injection pump in a short time. The experimental results show that the flow detector can measure the micro-flow rate from 1mL/h to 1500mL/h, and can not only respond to the micro-flow rate of 1mL/h quickly, but also the maximum allowable error of instantaneous flow rate is less than ±1%. The maximum allowable error of cumulative flow rate is less than ±1% when the volume of liquid in the injection chamber is larger than 5mL.
