摘　　要：血液透析机是模拟人体肾功能,纠正体内电解质与维持酸碱度平衡的一组体外平衡装置,其相关参数测量结果的质量控制直接关系到患者的身体健康。本文通过GUM法对血液透析机电导率示值误差、温度示值误差、静脉压示值误差、流量示值误差的测量结果进行不确定度来源分析,并利用贝塞尔公式法、极差法和经验法等对相关参数的测量结果进行不确定度评定。Hemodialysis machines are a group of external balance devices that simulate human renal function,correct electrolytes in the body,and maintain acid-base balance.The quality control of the measurement results of their related parameters is directly related to the life and health of patients.This article uses the GUM method to analyze the sources of uncertainty in the measurement results of electrical conductivity indication error,temperature indication error,venous pressure indication error,and flow indication error of hemodialysis machines,and uses the Bessel formula method to analyze the sources of uncertainty.The range method and empirical method are used to evaluate the uncertainty.
