面向术前焦虑症的低频理疗仪研制
|
摘要
本文基于经皮穴位低频电刺激的镇静效应和医学机理研制了一台面向术前焦虑症的智能音乐低频脉冲理疗仪。硬件部分以ATmega128单片机作为主控芯片,设计了刺激主电路、电源电路、音乐播放、低通滤波器、外围电路。软件部分设计了正弦脉宽调制波形输出、DA转换限流、液晶显示、音频解码等多个程序。相关测试实验和初步的临床观察表明,该仪器输出波形平缓,频率变化衔接流畅,具有良好的缓解术前焦虑的疗效。
Based on the medical mechanism and sedative effect of transcutaneous electrical acupoint stimulation, a smart music low frequency pulse physiotherapy instrument to relieve preoperative anxiety was designed. ATmega128 was used as the main control chip in the hardware part. Excitive main circuit, power supply circuit, music player, low-pass filter and peripheral circuit were designed. In the software part, procedures such as sine pulse width modulation waveform output, DA conversion current limiting, LCD display, audio decoding etc. were designed. The relevant test experiments and preliminary clinical observations show that the instrument output waveform is gentle, the frequency change is fluent, and it has a good effect on relieving preoperative anxiety.
