It will cause hidden trouble on clinical application if the uroflowmeter is out of control. This paper introduces a scheme of uroflowmeter calibration device based on digital signal processor (DSP) and gear pump and shows studies of its feasibility. According to the research plan, we analyzed its stability, repeatability and linearity by building a testing system and carried out experiments on it. The flow test system is composed of DSP, gear pump and other components. The test results showed that the system could produce a stable water flow with high precision of repeated measurement and different flow rate. The test system can calibrate the urine flow rate well within the range of 9~50 mL/s which has clinical significance, and the flow error is less than 1%, which meets the technical requirements of the calibration apparatus. The research scheme of uroflowmeter calibration device on DSP and gear pump is feasible.
