人体血压测量是医学电子学教学实验的重要组成部分,基于LabVIEW的虚拟仪器应用于教学实验是对传统教学方法的一种改革,利用信号调理电路和LabVIEW构建一个人体血压信号的采集和处理系统可使学生对血压信号乃至其它人体生理信号有全面、直观的了解。通过血压波形的显示、文件操作、信号及频谱分析等实验表明LabVIEW进入实验教学对学生了解和掌握虚拟仪器这一先进的测量技术,提高学生的学习积极性是很有帮助的。
Human blood pressure measurement is an important part of medical electronics teaching experiment. The application of virtual instrument based on LabVIEW in teaching experiment is a reform of traditional teaching methods. The system of signal conditioning and LabVIEW can be used to build a human blood pressure signal acquisition and processing system. So that students have a comprehensive and intuitive understanding of blood pressure signals and even other physiological signals. Experiments on the display of blood pressure waveform, file operation, signal and spectrum analysis show that LabVIEW into experimental teaching is very helpful for students to understand and master the advanced measurement technology of virtual instrument and improve their learning enthusiasm.
