调制中频生物电刺激的探讨与设计
发布时间：2018-11-17 10:59
【摘要】：由低频正弦调制的中频脉冲,不仅能克服中频脉冲治疗易被肌体所适应的缺点,而且还能使肌体所能承受的治疗阈值与治疗中的疼痛阈值明显分离。通过多方面分析得出,调制中频脉冲更适合作为治疗脉冲,而且较低频和中频脉冲有更好的治疗效果,同时综述了影响调制中频脉冲治疗效果的主要因素,如载波频率、调制方式、调制频率、调制幅度、调制波形等。最后设计了一个基于单片机的便携式调制中频电疗仪,经过周期性时间函数调幅的治疗机比原始的等幅输出脉冲的治疗机在克服肌体适应性方面有很大优势。
[Abstract]:If pulse modulated by low frequency sinusoidal can not only overcome the shortcomings of if pulse therapy which is easily adapted by the body, but also separate the treatment threshold which the body can bear from the pain threshold in the treatment. It is concluded that modulation of intermediate frequency pulse is more suitable for treatment pulse, and it has better therapeutic effect than low frequency and if pulse. At the same time, the main factors that affect the therapeutic effect of modulation if pulse, such as carrier frequency, are summarized. Modulation mode, modulation frequency, modulation amplitude, modulation waveform, etc. At last, a portable modulating medium frequency electrotherapy instrument based on single chip microcomputer is designed. The treatment machine with amplitude modulation of periodic time function has a great advantage in overcoming the adaptability of the body compared with the original one with equal amplitude output pulse.
