摘　　要：目的:研究基于数字信号处理(DSP)和齿轮泵的称重式尿流率计校准装置在临床应用中的可行性。方法:以DSP和齿轮泵为主体设计尿流率计校准装置,选用加拿大LABORIE的94-R01-BT尿流率计和荷兰MMS的PE10尿流率计,分别对尿流率计校准装置进行直线校准和曲线较准,比较其输出结果与尿流率计输出结果的一致性。结果:LABORIE尿流率计输出结果与校准装置相差较大,MMS尿流率计输出结果与校准装置相符。结论:所设计的尿流率计校准装置达到设计要求,可以应用于临床对尿流率计进行校准。Objective To research the feasibility in clinical application of weighing typeuroflowmeter calibration device based on DSP and the gear pump. Methods： With DSP andthe gear pump as the core conducted calibration device, we use the device in two urine flowrate meter-LABORIE and MMS for clinical trials, conduct linear and curve calibrations, andtest the data consistency between calibration device and the urine flow meter. Results： Datafrom LABORIE exist difference with calibration device while MMS is in accordance with it.Conclusion： The uroflowmeter calibration device has met the design requirements, and it canapply in clinical calibration.
