摘　　要：为了保证除颤能量发生器释放能量的准确性、可溯性和可比性,并为医疗设备生产企业和各级医疗设备检测机构开展注册检验、计量溯源等提供可靠的仪器,采用信号处理的时域分析方法研究除颤能量发生器的电路关键参数。首先分析除颤器电路并简化放电回路模型,采用Matlab仿真RC、RLC放电回路,探究除颤器的电感、电容和电压参数。其次选择医用除颤仪的电路关键参数同仿真得到的结果进行对比分析和定量评价,最后对外部阻抗的改变而影响测量的准确性进行实验测定。结果表明:除颤能量发生器电路关键参数的研究符合理论分析与客观实际情况,为医用除颤仪器的设计和电路特性的匹配提供了新的研究思路。In order to ensure the accuracy of the defibrillation energy generator to release energy,traceability and comparability,provide reliable instruments for medical equipment manufacturing enterprises and medical equipment inspection agencies to carry out the registration inspection,measurement traceability and so on,the paper uses the time domain analysis for signal processing to study the circuit key parameters. Firstly,defibrillation energy generator circuit is analyed,and the model of the discharge circuit is simplified. Matlab is used to simulate RC and RLC discharge circuit.Parameters of inductance,capacitance and voltage are Analyed. Secondly,the key circuit parameters of medical defibrillator are comparative analyzed and quantitative evaluated by simulation results. Finally, the accuracy measurement is completed by external impedance changed. The results show that studying on the defibrillation energy generator circuit key parameters accords with theoretical analysis and actual situation. It provides new ideas for medical defibrillation instrument.
