摘　　要：中频干扰电治疗仪治疗效果与干扰差频、调制幅度、调制频率有密切的关系.针对市场上治疗仪治疗方案单一的现状,本文提出频率、幅度可根据病人实际情况自由调节的治疗仪设计方案,并使用FPGA驱动的TFT显示界面,实时监控治疗仪运行情况和作用人体的电场变化,实现人机交流,方便操作.经改进的中频干扰电治疗仪,功能更加强大,治疗效果更佳,操作更加直观、简便.The curative effect of intermediate currency therapeutic unit is closed related with beat frequency, modulation am- plitude and modulation frequency. In view of the fact that the treatment of intermediate currency therapeutic unit is humdrum, this paper propose a method to improve the performance of this therapy apparatus. The frequency and amplitude can be regulated flexibly, and the equipment is equipped with TFTLCD. The electric field acted on human body can be monitored and man - machine communication is realized in time. The improved intermediate currency therapeutic unit is with complete functions and it can reach better treatment effect through simple operations.
