随着现代电子技术和医学科学的不断发展,生物医学测量仪器的种类也愈来愈多,可用仪器测量的生物体参数指标也日渐增多。生物体参数有生物电信号(如心电、脑电、肌电等)和生物非电信号(如呼吸、血压、脉搏等);在教学实验以及科研工作中,要直观地、准确地对生物体的呼吸进行观察和分析,可将非电信号的呼吸信号转换成电信号,经放大处 With the continuous development of modern electronic technology and medical science, there are more and more types of biomedical measuring instruments, and more and more organism parameters are measured by available instruments. Biological parameters of bioelectric signals (such as ECG, EEG, EMG, etc.) and biological non-electrical signals (such as breathing, blood pressure, pulse, etc.); teaching experiments and scientific research, to be intuitive and accurate for biological Body breathing observation and analysis, non-electrical signals can be converted into respiratory signals, amplified by the Department
