摘要
本文主要介绍透射式脉搏血氧饱和度(Oxygen Saturation,SpO2)的检测方法,在分析SpO2模拟仪设计原理的基础上,阐述了SpO2模拟仪校准装置的功能和使用方法,并对校准装置的基本性能进行了实验验证。实验结果表明,SpO2模拟仪校准装置不仅具备很好的测量重复性和稳定性,对目前在用的SpO2模拟仪也具有普遍适用性。校准装置同时具备高灵敏度和智能化的特点,并预留了充分的功能扩展空间以满足SpO2模拟仪技术发展带来的计量需求。
In this paper,we introduced the detection method of transmittance oximetry,and the function and application method of the pulse oximeter simulator calibration equipment based on the analysis of the design principle of pulse oximeter simulator. Meanwhile,the basic performance of this calibration equipment was also experimentally verified.Experimental results indicated that the pulse oximeter simulator calibration equipment not only had good repeatability and stability during measurement, but also had universal applicability for various pulse oximeter simulators currently in use.The calibration equipment has the characteristics of high sensitivity and intelligence,and has reserved sufficient functional expansion space to meet the metrological requirements brought by the technology development of pulse oxi meter simulators.
