中文摘要: 为了提高肺功能测量值的准确性,减少临床呼吸疾病的错误诊断,采用精确控制的模拟肺装置对肺功能测量进行校准。简要介绍模拟肺装置的基本结构、工作原理、气体的计算方法、工作模式。采用模拟肺装置对肺功能仪进行校准测试的实验方法,肺功能仪的流量线性和工作模式进行了测试,分析了肺功能仪在各种工作模式下的体积误差。被校准的肺功能仪的流量线性、肺活量、用力肺活量的体积误差小于3.5%,静息通气量误差小于2%,最大通气量误差小于10.5%。通过对测试数据的分析和说明,被校准的肺功能仪测试值在ATS和ERS的标准范围内,达到对肺功能仪进行校准的目的。实验研究为模拟肺装置的广泛运用提供参考依据,首次在国内为肺功能仪的质量控制和计量校准提供量值溯源。

Abstract:In order to improve the measurement accuracy of pulmonary function and reduce clinical diagnosis errors of respiratory diseases,the precision controlled lung simulator was used for pulmonary lung function measurement calibration. The lung simulation device’s basic structure and principle, the method of calculating gas volume, and work mode were described. The volume errors on flow linearity and all kinds of work mode was studied. The spirometer was calibrated by the lung simulator and its volume relative errors were less than 3.5% for the flow linearity and vital capacity and forced vital capacity, less than 2% for minute ventilation and less than 10.5% for maximum voluntary ventilation. Based on the test data and the analysis, calibrated pulmonary function test values were within the ATS and ERS standards, and this reaches on calibration purposes for the spirometer. Experimental study of lung simulator application provides reference for the extensive use of lung simulation devices. It is the first time in domestic metrology to provide quality control, measurement calibration and traceability for the spirometer device.
