医用电动止血带校准方法和不确定度评定

Calibration Method And Uncertainty Evaluation of Medical Electric Tourniquet

医用电动止血带属于手术室、急诊室、诊疗室设备,主要用于手术室供阻断人体肢体血流用。其中压力传感器是其计量溯源的主要内容。近年来,对医用电动止血带的校准需求越来越多,但目前并未有相关的研究。本文通过研究医用电动止血带的校准方法,并对其自动泄压功能、校准方法和校准进行不确定度评定,为医疗计量工作提供参考。

Medical electric tourniquet belongs to the operating room,emergency room,consultation room equip⁃ment,mainly used in the operating room for blocking the blood flow of human limbs.Pressure sensor is the main content of its metrological traceability.In recent years,there is an increasing demand for the calibration of medical electric tourniquet,but there is no relevant research at present.This paper studies the calibration method of medical electric tourniquet,and evaluates the uncertainty of its automatic pressure relief function,calibration method and calibration,so as to provide reference for medical metrology.
