1、 1 毕业设计（论文） 脉搏测试仪的设计 The Pulse test instruments design 2 摘要摘要 人体的脉搏所呈现给医生的各方面信息，能反映出人体心血管系统以及各项 生理状况。在过去，人们大都靠自己的手、眼去感知脉搏，靠经验去观察病人的 情况，但是却易受医生主观方面的种种因素影响到正常的观察。进入近代，随着 电子工程学科的发展。脉搏的检测便交给了仪器，经过不断完善。心律的检测不 再受医生主观方面的影响，从而变的更加稳定可靠。 我们采用红外透射式传感器和 MSP430 单片机设计了一种简单有效的心电采 集测量系统。通过红外光电透射式传感器，把生物电信号传送到放大器，由于
2、生 物电信号比较微弱，信号还需要经过二次放大，放大后的信号进过 A/D 转换由 MSP430 单片机采集。心律波形可以在液晶屏上显示，也可通过串口传送到个人 计算机。 最后选用了一个上位机程序， 可以为医生提供病人的远程诊断参考数据。 经实物验证，我们的设计实现了脉搏测试仪的基本功能，与市场销售的便携 式脉搏监测仪对比后发现误差在3%以内。符合设计要求。 关键字关键字：单片机 MSP430，红外透射式传感器，上位机。 3 Abstract The pulse of the human body are presented to the doctors various aspects infor

4、modern times, with the development of electronic engineering discipline.Pulse detection to the instrument, through continuously improve.Rhythm of the test is no longer affected by the doctor subjective aspect, and become more stable and reliable. We adopt the infrared transmission type sensor and MSP430 single chip microcomputer to design a kind of simple and effective ecg collection and measurement system.By referring to clamp type sensor, the biological electrical signals sent to the ampl
