面向脉诊客观化的脉搏传感器研究综述

Research review on pulse sensors for pulse diagnosis objectification

脉诊客观化是利用现代仪器和设备,客观记录脉象信息、提出分析方法与参数指标,并结合中医脉象信息量化原理服务中医病证辨识的过程。由于脉搏信号质量直接影响脉象分析的方法和结果,脉诊客观化研究的重要内容是脉象信息的采集和处理,关键在于脉搏传感器的选择。本文从脉诊客观化的国内外研究进程以及目前所面临的客观化标准不统一、无法广泛应用于临床等问题出发,列举分析了压力式、光电容积式、光纤式传感器等几种典型的脉搏传感器及其在脉搏监测系统中的应用现状。本文重点介绍了脉诊仪的柔性、面阵式压力传感器,及其在多位点脉搏检测性能上的优势,并展望了脉搏传感器的发展方向及应用领域,为中医脉诊传感器及客观化的进一步研究提供了新的思路。

Objectification of pulse diagnosis is a process of combining the quantitative principle in traditional Chinese medicine(TCM)to objectively record pulse information,propose analysis methods,and serve for the disease and syndrome identification,by using advanced instruments and equipment.Since the quality of pulse signal directly affects the method and result of pulse analysis,the important content of objectification research of pulse diagnosis is the collection and processing of pulse information,and the key lies in the selection of pulse sensor.Starting from the research progress of the objectification of pulse diagnosis at home and abroad,and the problems that the objectification standards are not unified and can not be widely used in clinical practice,this paper lists and analyzes several typical pulse sensors such as pressure type,photoelectric volumetric type and optical fiber type sensors,and their application status in pulse monitoring system.This paper emphasizingly introduces the flexible and planar pressure sensors of pulse instrument,and its advantages in the performance of multi-site pulse detection,and prospects the development direction and application fields of pulse sensor,which provides a new idea for the further study of pulse sensor and objectification of traditional Chinese medicine.
