摘　　要：医用电动洗胃机流量量值的准确性对患者洗胃效果起到关键影响作用,针对电动洗胃机双向非稳流液体流量测量模型开展校准方法研究,研制医用电动洗胃机检测装置将流量量值溯源于质量和时间,解决了临床医疗机构、厂家和计量检测单位不便于现场校准电动洗胃机的问题。实验结果表明,校准装置流量测量范围为50~3000 mL/min,压力测量范围为-60~90 kPa,满足医用电动洗胃机关键参数溯源要求。The accuracy of the flow value of the medical electric gastric lavage machine plays a key role in the gastric lavage effect of the patient.The calibration method of the electric gastric lavage machine is developed for the two⁃way unsteady liquid flow measurement model,and the calibration device of the medical electric gastric lavage machine is developed to reduce the flow volume.The value is traceable to quality and time,which solves the problem that it is not easy for clinical medical institutions,manufacturers and measurement and testing units to calibrate electric gastric lavage machines on site.The experimental results show that the flow measurement range of the calibration device is 50~3000 mL/min,and the pressure measurement range is-60~90 kPa,which meets the traceability requirements of the key parameters of the medical electric gastric lavage machine.
