摘　　要：为满足脉搏血氧仪类医疗器械电磁兼容(EMC)测试的特殊要求,该研究设计了一种气动式血氧饱和度模拟器。该模拟器设计了一种可放置于电波暗室内的专用无源模拟手指和气囊,并通过气路与暗室外的控制主机连接,可在主机控制下产生模拟的脉搏血氧信号。经与常规电子式血氧饱和度模拟器的EMC比对测试,证明该气动式血氧饱和度模拟器可有效消除模拟器引入产生的影响。In order to meet the special requirements of electromagnetic compatibility(EMC)testing of pulse oximeter medical devices,a pneumatic oxygen saturation simulator was designed in this paper.A dedicated passive analog finger and airbag that can be placed in an anechoic chamber were designed in the simulator,connecting to the control host outside the anechoic chamber through the air path,which can generate the simulated pulse oxygen signal under the control of the host.Through the EMC comparison test with the conventional electronic oxygen saturation simulator,it was confirmed that the pneumatic oxygen saturation simulator can effectively eliminate the impact of the introduction of the simulator.
