摘　　要：针对目前使用最为广泛的双光束投射式脉搏血氧仪提出一种基于生物组织光学特性的光传输模型,进而设计一种脉搏血氧仪校准装置,包括装置整体结构、模拟手指、光源驱动电路等。依据JJF 1542-2015《血氧饱和度模拟仪校准规范》进行实验验证,结果表明,采用该方法设计的脉搏血氧仪校准装置具有结构简单、示值准确的特点。Aiming at the most widely used dual-beam projection pulse oximeter,a light transmission model based on the optical characteristics of biological tissue is proposed,and then a pulse oximeter calibration device is designed,including the overall structure of the device,analog finger,light source drive circuit,etc.According to the JJF 1542-2015"Blood Oxygen Saturation Simulator Calibration Specification"for experimental verification,the results show that the pulse oximeter calibration device designed by this method has the characteristics of simple structure and accurate indication.
