届毕业生 毕业论文 题 目: 激光辅助治疗仪的设计 院系名称： 电气工程学院 专业班级： 学生姓名： 学 号： 指导教师： 教师职称： 讲 师 年 06 月 10 日 摘 要 近年来随着生活水平的提高，人们对健康的关注程度的逐渐增加，相应的对医疗设备的关注也得到进一步提高。该课题所研究的激光治疗法是一种非常安全的治疗方法。 该课题设计的激光治疗仪是一种医用器械，以AT89S52单片机为核心，采用5V电源供电，利用激光发射器件发射激光，作用于人体敏感部位，产生辅助治疗作用。利用按键对激光器发送的脉冲形式和时间进行控制，从而使末端激光器发射出最适宜身体接受的光波。为了解决治疗强度和治疗时间的问题，我们采用了四位LED数码管动态显示治疗时间，并设置了三个按键，一个用来控制治疗强度，也就是控制激光发射头高低电平的切换，两个按键用来控制治疗时间的加减。为了提醒使用者是否真的采取按键操作功能，我们设计了当有按键按下时蜂鸣器发出报警信号以确定是否采取该操作。利用C语言设计相应的软件实现其功能。 该课题设计的治疗仪以单片机为核心，完成了所需要的各项功能，具有结构简单、使用方便的特点。 关键词：单片机；激光治疗仪；LED Title Design of Laser Aid Treatment Instrument Abstract In recent years，along with the living standard’s enhancement, people’s attention to health gradually increases, correspondingly the attention to medical equipment also has further enhancements. The laser instrument which this topic studies is a very safe method of treatment auxiliary. As a kind of medical instrument, this laser treatment meter, in view of its design, AT89S52 was took monolithic integrated circuit as the core, and 5V power source was used for supplying power and laser transmission component for launching laser. It affects in the human body’ sensitive spot, and has the aid therapeutic action. The meter carries on the control to the pulse mode and time which the laser transmits, thus it makes the terminal laser to launch suitable light waves which the body accepts.In order to solve the problem that patient’s treatment time and intensity is different, we use four LED nixie light dynamic demonstration to demonstrate the treatment time, It has three pressed keys, two pressed keys are used for controlling the treatment time’s addition and subtraction, one for the treatment intensity and one used for treatment meters height level cut. In order to remind the curer of the treatment conclusion and to make the operation easy, this design uses the software to control pressed
