基于51的医学中频治疗仪的设计
|
摘要
为了解决众多上班族和中老年人群体不断饱受慢性疾病危害的问题,设计并实现一套医学中频治疗仪系统。系统由按键模块、显示模块、模数转换(DAC)模块、放大模块、电源模块和微处理器控制模块组成,能够输出多种医学调制中频电脉冲。系统采用51单片机作为控制模块,按照经皮神经电刺激镇痛原理,实现组合输出调制中频电脉冲的功能;并根据用户自身的反应情况,实现治疗电脉冲频率、强度和时间的调节功能。系统中设计的多级滤波电路,对电脉冲整个调制和输出过程进行滤波和校正,确保医学调制电脉冲输出的准确性。最终调试结果表明,该医学中频治疗仪输出的治疗电脉冲与电疗规范脉冲基本一致,能够为慢性疾病防治起到参考作用。
In order to solve the problem that many of the workers and the elderly continue to suffer from the chronic diseases,an intermediate frequency therapeutic apparatus system was designed and implemented.The system consists of a key module,a display module,a DAC module,an amplifying module,a power supply module and a microprocessor control module,and can output a variety of modulated IF pulses.The system uses 51 single-chip microcomputer as the control module,according to the principle of percutaneous nerve stimulation analgesia,the function can be achieved to output modulation IF pulses combined.On the basis of the user's own reaction,the regulation function of the electric pulse frequency,intensity and time was achieved.A multistage filter circuit was designed to filter and correct the entire process that ensures the accuracy of the modulated IF pulses' output.The final debugging result shows that the system's pulses were basically consistent with the standard IF pulses,and can serve as a reference for the prevention and treatment of chronic diseases.
