摘　　要：为了改善常规电刺激治疗仪刺激参数不规范、采用被动治疗模式疗效不佳等缺陷,设计开发了以微处理器为核心的听视觉生物反馈式功能性电刺激仪。借助语音信号和可视化信号提示,促使训练者能主动参与训练;创新地实现了刺激电流实时监测和调节功能,便于医生根据患者病情设置刺激强度;采用可编程式触摸屏人机交互方式,使治疗参数准确量化。通过测试可知:该仪器实现了刺激参数的无级调节、显示和量化,有利于不同参数下的疗效评价对照,提高了电刺激的准确性和可重复性。In order to improve the conventional stimulator with non-standard parameters and poor efficacy using the passive mode of the treatment,the stimulator employing an audio-visual feedback is developed based on the microprocessor technolo- gy.With the reminder of both voice and visualization signal, trainers can take the initiative to participate in training and try his best to generate a weak electromyographic signal.The real-time monitoring and regulating function for the stimulating cur- rent is innovatively achieved.Through the above function, it＇s easy for doctors to set up the stimulating intensity according to different patients.In the newly designed stimulator, programmable interactive way using touch-screen is employed so that the treatment parameters can be accurately quantified and set up.The test shows that treatment parameters have achieved step- less adjustment,display and accurately quantification.It＇s beneficial to contrast the efficacy under different parameters and im- prove the accuracy and repeatability of the stimulator.
