智能电疗仪的设计与制作摘要在医疗器械领域里,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。根据目前电疗治疗仪现状与不足,研制一种新型便携式智能电疗仪。该电疗仪采用电疗的机理,选用美国ATMEL公司的低功耗的AT89S52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。为实现上述目的,本设计采取以下设计方案:电路部分选用ATMEL公司的AT89S52单片机为控制核心,具有键盘扫描、治疗时间及治疗强度显示、D/A转换和两路波形信号放大输出等功能。该电疗仪的12种不同的治疗波形通过对若干种低频频率的脉冲进行调制获得。治疗时间由用户在治疗前自行设定,范围为0~40分钟。在治疗过程中,治疗电信号的强度由用户根据自身的反应情况进行相应的调节,范围为0~50档。该电疗仪的电刺激信号通过两个外接配件作用于人体,外接配件为治疗专用电极。

Abstract
In the field of medical equipment, electrotherapy equipment development have been greatly, but some of Miriam electrotherapy treatment deficiencies made it difficult to be widely used. Therapeutic apparatus according to the present status of electrotherapy and inadequacies of the development of a new type of portable intelligent instrument electrotherapy. The instrument used electrotherapy electrotherapy mechanism, selection of the United States ATMEL's the AT89S52 low-power single-chip microcomputer to control the core, with the keyboard scanning, data showed the changing intensity and frequency of pulse output functions. Electrotherapy treatment through the portable intelligent instrument design, to explore a development of portable medical equipment smart ideas and for the development of other therapeutic equipment designed to provide a reference. To achieve the above objectives, the design of the following designs: partial circuit ATMEL Corporation AT89S52 selected for the control of single-chip core, with the keyboard scanning, treatment time and treatment intensity display, D / A conversion and two-way wave output signal amplification and other functions . The 12 kinds of electrotherapy instrument waveforms of different treatment on certain types of low-frequency pulse frequency modulation was carried out. Treatment time by the user to set pre-treatment, the range of 0 ~ 40 minutes. In the course of treatment, treatment intensity signal by the user according to their response to the necessary adjustments, the range of 0 ~ 50 files. The instrument electrotherapy stimulation signal through two external accessory role in the human body, external parts for the treatment of special electrodes.
