摘　　要：超声波在介质内传播时,会使介质质点受到交变压力,对组织内物质和微小的细胞结构形成一种摩擦的作用。该作用引起细胞功能的改变,改善血液和淋巴循环,增强细胞膜的弥散过程,从而改善新陈代谢,提高组织再生能力,具有重要的医学意义。本文提供了一种基于脉搏信号控制的智能超声波理疗装置及其实现方法,通过脉搏波信号的采集和处理,实现超声效应与人体心血管系统共振,提高超声波的治疗效益。在治疗中,本系统能够对超声输出功率进行实时监控和调整,避免在使用过程中出现谐振频率不稳定,确保了系统的稳定和高效。While ultrasonic wave propagating in the medium, the medium particle fall under alternating pressure, which forming a friction role in the organization of substances and micro cell structures. This effects cause cell function change, improve blood and lymph circulation, enhance the diffusion process of the cell membrane, thereby improving the metabolism and enhancing tissue regeneration ability, which consequently has important medical significance. This paper provides an intelligent ultrasonic physiotherapy device based on pulse signal and its implementation method. By this means, it realizes the resonance of the effect of ultrasound and the human cardiovascular system, which boosts the benefit of ultrasonic treatment. In the treatment, the system could accomplishes real-time monitoring and adjusts the output of ultrasonic power, to avoid resonance frequency instability in the process, which ensures the stability and efficient of the whole system.
