利用光纤传感器的脉象仪研究

本文叙述了所研制的脉象仪的原理、结构和实验结果。用特殊设计的光纤位移传感器作为脉象传感器。将它放在待测的脉动部位,它将感受脉象,并将此脉象信息传递给传感器的反射膜。反射膜随脉象产生不同角度的倾斜,从而改变进入接收光纤的光信号。此光信号的变化将反映脉象信息。携带脉象信息的光信号经光电探测器转换为电信号,又经放大、滤波、整形之后在显示器上显示脉象图。分析脉象图的频率、幅度及其规律性,并通过与典型病人的脉象图比较,便可诊断病人的疾病性质和病情。初步实测表明,该脉象仪具有精度高、结构简单、使用方便等特点,为中医诊断客观化和科学化提供了一种新的有效的手段和方法。

EXPERIMENTAL STUDY OF ARTERIAL PULSE DETECTOR WITH OPTIC FIBER SENSOR

This paper proposes a new arterial pulse detector using optic fiber sensor, and describes the theory, experimental set-up and experimental results of the apparatus. The optic fiber sensor is the detecting part that can detect the arterial pulses. The optical signal of the arterial pulses will be transformed into electrical signal. After signal processing, the image of arterial pulses is displayed on an oscilloscope.
