摘要
除颤过载恢复是心电电极的重要电性能,它的优劣直接影响到除颤后心电波形的检测和显示,进而影响对患者的抢救和治疗进程。文中开发了一种心电电极除颤过载性能测试系统,根据最新医药行业标准,基于C8051F340的硬件系统,通过USB协议进行数据传输,在LabVIEW的软件平台上,实现了对除颤恢复性能指标的检测(包括交流阻抗的测试)。系统采用良好的电隔离控制和检测,能精确控制测试过程中的充放电时间。实验结果表明,该系统能准确有效的测试电极对的除颤过载恢复性能,并具有安全、准确、操作简单等优点。
Defibrillation overload recovery performance is one of the most important electrical properties of ECG electrodes, which directly affects the ECG display after the patient is defibrillated, thereby affects the diagnosis and treatment of the patient. A defibrillation overload recovery performance test system for ECG electrodes was developed according to the latest pharmaceutical industry standards and based on the C8051 F340 hardware system. With USB protocol data transfer, the detection of defibrillation overload recovery performance parameters （ including AC imped- ance） is implemented on LabVIEW software platform. The system has good electrical isolation control, which can accurately operate the charging and discharging this system has good performance, and features time during test process automatically. Experiment result shows that safe, accurate and easy to operate.
