摘要
提出了基于嵌入式系统的便携式三叉神经疼痛射频治疗仪的设计方案。实现了预检、脉冲射频治疗以及连续射频治疗的功能,并通过触摸屏以及液晶显示的图形用户界面进行操作。同时根据系统特点采用改进的分段PID温度控制算法,温度精度小于1℃,满足临床应用的要求。
A design of miniature radiofrequency device based on embedded system for the treatment of trigeminal neuralgia is proposed. The functions of pre-therapy stimulation,pulsed therapy and continuous therapy are accomplished. The Graphic User Interface and touch panel facilitate the operation. Meanwhile, modified PID algorithm for temperature control is adopted, reaching precision of 1 ℃ , and that can meet the demand of clinic.
