基于间歇脉冲快速充气的空气波按摩装置控制系统的研究

Research on control system of air wave massage device based on intermittent pulse rapid inflation

本系统根据空气波原理,利用气囊内空气压强的变化对肢体组织进行按摩,起到加速静脉血流速度的作用,适用于辅助治疗和消除肢体淋巴水肿等症状。系统主要由气体压缩单元、传感器单元、控制核心单元、电磁阀、微型气泵、电源、触摸屏、配套气囊及管路组成。控制核心单元通过软件程序控制微型气泵和电磁阀,令气体压缩单元压缩空气,达到预定压力后,向配套气囊快速充气、放气,达到按摩下肢的目的。触摸屏可以设定治疗时间、预定气囊压力、显示气囊的实时压力等。该系统对偏瘫、截瘫、瘫痪患者的肢体按摩和康复都有功效。

According to the principle of air wave,the change of air pressure in the air bag is used to massage the limb tissue.The massage accelerate the speed of venous blood flow.It is suitable for the treatment and elimination of limb lymphedema and other symptoms.The system is mainly composed of gas compression unit,sensor unit,control core unit,solenoid valve,micro air pump,power supply,touch screen,supporting air bag and pipeline.The control core unit controls the micro air pump and the solenoid valve through software program to make the gas compression unit compress air.When the preset pressure is reached,the air bag is quickly inflated and deflated to achieve the purpose of massaging the lower limbs.The touch screen can set the treatment time,preset air bag pressure,display the real-time air bag pressure,etc.The system is effective for limb massage and rehabilitation of hemiplegia,paraplegia and paralyzed patients.
