摘要
为解决在建立快速心房起搏房颤模型时快速起搏系统对通信干扰、通信距离等问题,设计一种基于433MHz无线通信频率进行组建星型网络的低功耗可植入式起搏系统。该系统包括植入式起搏器、程控头和程控软件,起搏器由无线通信模块、起搏模块、心电采集模块、电源管理模块组成,程控头作为星型网络中间节点,经由上位机程控软件程控网络中的起搏器。介绍了系统各部分的硬件设计和软件流程,描述了该系统进行模拟实验和动物试验的结果,结果表明所设计系统和应用方法对快速心房起搏房颤模型是有效且可行的。
In order to solve the problem of communication interference and communication distance caused by the rapid pacing system when establishing the rapid atrial fibrillation model,a low-power implantable pacing system based on 433 MHz communication frequency to form a star network is designed.The system includes an implantable pacemaker,a programmer head,and programmer software.The pacemaker is composed of a wireless communication module,a pacing module,an ECG monitoring module,and a power management module.The programmer head acts as an intermediate node in the star network and is controlled by PC programmer software to program each pacemaker.This article introduces the hardware design and software flow of each part of the system,and describes the results of in vivo simulation and in vivo animal models of the system.The results show that the designed system and application method are effective and feasible for the rapid atrial pacing atrial fibrillation model.
