| 中文摘要 | 经皮能量传输(TET)在近年临床实践中暴露出严重的热伤害风险,引发了多例病人烫伤及大规模的设备召回。针对该问题,该文将体外发射功率调整与体内充电功率调整相结合,提出外环温度控制、内环功率控制的双闭环能量传输方案。根据植入线圈的接收功率调整体外发射功率,确保植入设备接收的能量恰好满足后端电池充电所需,维持稳定能量传输并避免额外功耗及发热;根据植入设备温度调整体内电池充电功率,改变设备的功率需求及发热量,避免热伤害。通过离体、活体实验,验证控制方案的有效性。结果表明,双闭环系统在保障温度安全的同时实现了快速的能量传输,为相关植入式医疗设备提供了一套安全有效的能源解决方案。; Thermal hazards caused by transcutaneous energy transmission(TET)have resulted in skin burns and led to a global recall of rechargeable neuromodulation devices in recent clinical practice.This paper presents a double closed-loop TET scheme consisting of an outer temperature control loop and an inner received power control loop.The transmit power from the external coils is adjusted according to the received power from the implanted coils to charge the implanted battery while maintaining stable energy transmissions.The charging power for the battery is adjusted according to the implant temperature to control the heat production and prevent overheating.In vitro and in vivo experiments verify the safety and efficiency of the TET controller which provides a viable solution for charging implantable medical devices. |
