摘　　要：设计了1种可以进行调幅、调频控制的磁刺激治疗仪。采用MAX038信号发生器产生正弦信号,经过OPA549进行功率放大,通过单片机控制刺激时间、信号幅度和频率,并应用六位数码管显示信号幅值、频率、时间等参数。采用Ansoft有限元分析软件对磁场探头进行了磁场仿真,为磁刺激器治疗强度的设定提供了理论依据和参考标准。A magnetic stimulation instrument is desighed, whose amplitude and frequency can be adjusted. The MAX038 chip outputs the sine signal, whose power will be amplified by OPA549. The single chip eontrolls the work time, amplitude and frequency. There are six seven-segment numeric displays for displaying the stimulation parameters of amplitude, frequency and work time. Ansoft is used to simulate the magnetic field of stimulating electrode, which provides theory basis and reference standard for the adjusting treatment of the power of magnetic stimulation instrument.
