摘要
设计了一款术后康复理疗仪,以生物安全型高频信号源为理疗信号,在深层进行电能与生物热能的转换。该理疗仪由电极、高频生物安全型信号源、嵌入式微控制器和电源组成。采用WinCE操作系统,应用分级式脉宽控制算法对信号频率与强度进行智能控制。测试表明,该理疗仪电磁兼容性好,安全性高,理疗效果明显。
This paper introduces a physiotherapeutic instrument which adapts to postoperative rehabilitation. It is based on the biological secure high frequency signal that converts electrical energy to biological energy under deep skin. This physiotherapeutic in- strument is mainly composed of electrode, high biological safety signal source, embedded micro controller and power. It employs WinCE operating system, applying hierarchical pulse-width control algorithm to control the frequency and strength of the signal in- telligently. Test results show that it has perfect EMC, high-security and high-efficlency.
