一种超声波冻疮治疗仪的研制

摘要

目的:研制一种超声波冻疮治疗仪,解决现有的临床冻疮治疗方法恢复效果不明显的问题.方法:基于超声波的热作用原理设计,以LPC1788微控制器为硬件电路核心,基于KEIL uvision4.0开发平台研制相应的配套软件.整个治疗仪由方波产生电路、升压电路、换能电路、液晶显示电路和电源电路构成.结果:利用该治疗仪连续治疗冻疮5～7 d就可以治愈,具有良好的治疗效果,无任何不良反应.结论:该治疗仪可靠性高、操控性强、适应范围广,无副作用,可以从一定程度上克服目前临床治疗冻疮方法的缺点,具有较好的应用前景.%Objective To develop an ultrasonic frostbite treatment instrument to enhance the efficiency of its treatment.Methods The instrument was designed with thermal effect of ultrasound,which used LPC1788 controller as the core of the hardware circuit.Corresponding software was developed based on KEIL uvision4.0 platform.The instrument was composed of the circuits for square wave generation,boosting,transduction,LCD and power source.Results Five-to-seven-day treatment by the instrument gained high efficacy,and no adverse response occurred.Conclusion The instrument has the characteristics of high reliability,strong controllability,wide adaptation and no side effects,and thus is worthy promoting practically for the clinical treatment of frostbite.
