面向术前焦虑症的低频理疗仪研制
Design of Low-Frequency Therapy Instrument for Preoperative Anxiety
摘要
Abstract
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.关键词
