摘要
目的为全方位监测心电信号并弥补单一导联心电检测的不足,设计并实现了一种基于无线能量传输技术的植入式三路心电遥测系统。方法系统由无线能量传输设备供能,植入式微型电子胶囊检测心电信号,数据记录仪无线接收数据并由数据处理软件处理。直流供电下分别采用模拟心电信号、正弦信号、方波信号通过模拟实验验证了系统的性能。无线供能下信号线屏蔽后并埋在猪肉中进行体外实验。结果模拟实验胶囊能够采集三种信号,体外实验测得有噪声的信号波形。结论直流供电下胶囊正常工作,无线供能下猪肉对磁场有一定程度的屏蔽作用。
Objective In order to monitor ECG signals comprehensively and remedy the defects of single ECG detection, an implantable three-lead ECG radio telemetry system based on wireless power transmission technology is designed and achieved. Methods The wireless power transmission device supplies energy for the system, the implantable miniature electronic capsule detects ECG signals, and the detected data are received by the data logger wirelessly and processed by the processing software. In the simulation experiment, simulated ECG signals, sine-wave signals and square-wave signals are used to prove the performance of the system respectively under DC power supply. In the experiment in vitro, the signal lines are shielded and buried in the pork under the wireless power supply. Results The three types of signals can be detected in the simulation experiment and the signal wave with noise is detected. Conclusions The capsule works properly under DC power supply. Pork has a certain degree of shielding effect of magnetic field under wireless power supply.
