基于P89LPC935便携式智能电疗仪的设计

The Design of Portable Intelligent Electrotherapy Instrument Based on P89LPC935 Microcontroller

在医疗器械领域里,电疗器械有了较大的发展,但目前电疗治疗仪的一些不足之处使其很难得到推广使用。本论文介绍了目前电疗治疗仪现状与不足,据此研制了一种新型便携式智能电疗仪。该电疗仪采用电疗的机理,选用Philips公司的低功耗的P89LPC935单片机为控制核心,具有键盘扫描、数据显示和频率强度不断变化脉冲波形输出等功能。通过便携式智能电疗治疗仪的设计,探索出一条研制便携式智能医疗器械的思路,为开发其它理疗器械提供设计参考。

In medical instrument domain, the electrotherapy instruments have a bigger development. But, the deficiency of electrotherapy instruments prohibits their widespread use. The thesis introduces the actuality and the deficiency of electrotherapy instruments, so I design a new portable intelligent electrotherapy instrument. The electrotherapy instrument, based on electrotherapeutics mechanism, has Philips companies low cost single-chip microcontroller - P89LPC935 as control core, which has some function, such as keyboard scan, data display, wave output which has mutative frequency and intensity. Via the design of portable intelligent electrotherapeutics instrument, we want to explore train of thoughts to design portable intelligent medical instruments, offering design consult of other physical medicine instrument.
