【摘要】 目的研究用于植入式医疗仪器的基于脉冲位置调制(PPM)方式的经皮无线双向通信解决方案。方法系统由植入体内的医疗仪器通信电路,体外应用程控器和掌上电脑PDA组成,植入体内的医疗仪器通信电路和程控器间的无线双向通信采用PPM脉冲调制方式。结果实现了植入体内的医疗仪器通信电路(钛壳封闭)和体外程控器间2英寸以上的无线通信距离,同时位置容差性较好。结论将PPM调制方式成功地应用于经皮无线通信系统,与ASK等调制方式相比,降低了植入体内的医疗仪器通信电路的功耗,通过天线共用设计减小了植入体内的医疗仪器通信电路体积。更多还原

【Abstract】 Objective To find out a PPM-based transcutaneous wireless bidirectional communication system for implantable medical device.Methods The wireless communication system included device implanted in the body,controller and PDA outside the body.Pulse position modulation(PPM) was used for the wireless bidirectional communication between device implanted in the body and controller outside the body.Results A PPM-based transcutaneous wireless communication system was realized.Its wireless bidirectional communication distance between device implanted in the body with titanium container and controller outside the body was over two inches.This system was with good position availability.Conclusion Pulse position modulation is successfully used for transcutaneous wireless communication system,and average power consumption for communication device implanted in the body is lowered greatly compared with ASK modulation method.At the same time,the volume of communication device implanted in the body is decreased for antenna common-using idea.更多还原
