Pneumatic and Control of Pneumatic Ballistic Shock Wave Therapeutic Instrument

针对气压弹道式冲击波治疗仪的结构及用途,本文基于气压弹道式冲击波治疗仪工作原理,对体外冲击波治疗仪控制系统进行设计。给出了气压弹道式体外冲击波的工作原理,采用气动回路作为体外冲击波治疗仪动力系统,该系统由气动控制回路和单片机构成,同时采用STC89C51单片机对气动回路的激发压力和频率进行控制,实现了治疗仪工作频率可在1~10 Hz内任意设定,对于不同病症,每次疗程冲击次数可动态调整和实时显示;利用压力施压指示器装置,根据患者症状和治疗部位施加不同的压力,得到相应的冲击波能量,拓展了应用范围,进一步提高治疗效果,该系统方案简单,操作方便,成本较低。该研究对体外病症治疗具有较高的应用价值。

According to the structure and application of pneumatic ballistic shock wave therapy instrument,the control system of extracorporeal shock wave therapy instrument is designed based on the working principle of pneumatic ballistic shock wave therapy instrument.The working principle of pneumatic ballistic extracorporeal shock wave is given,and the pneumatic circuit is used as the dynamic system of extracorporeal shock wave therapy instrument.The system is composed of pneumatic control circuit and single chip microcomputer,and the excitation pressure and frequency of pneumatic circuit are controlled by STC89C51 single chip microcomputer.The operating frequency of the therapeutic instrument can be set arbitrarily within 1~10 Hz.For different diseases,the impact times of each course can be dynamically adjusted and displayed in real time The pressure indicator device is used to apply different pressure according to the symptoms and treatment site of the patients,to obtain the corresponding shock wave energy,to expand the scope of application,and to further improve the therapeutic effect.The system is simple,easy to operate and low in cost.This study has high application value for the treatment of disease in vitro.
