从生物流体力学角度探讨脉象机制

Discussion on pulse mechanism from the perspective of biological fluid mechanics

脉诊是中医四诊的重要组成部分,其形成机制十分复杂,如何客观、规范的表达脉象形成是脉诊客观化发展亟待解决的问题。生物流体力学是多学科的综合与交叉,可客观反映人体循环系统的各项参数指标,从本角度探讨循环系统中桡动脉的形成机制是适合脉诊客观化研究的方法和途径。文章从多学科视角总结古今医学对脉象机制的认识,首次从生物流体力学角度系统阐述并解析脉象形成机制,以脉搏波、血液流动、血管壁运动及边界条件为纲解读脉象形成机制,为中医脉诊的客观化研究提供新的思路与方法。

Pulse diagnosis is an important part of the four diagnoses of traditional Chinese medicine. Its formation mechanism is very complex. How to express the pulse formation objectively and normatively is an urgent problem to be solved. Biohydrodynamics is a multi-disciplinary synthesis and crossover, which can objectively reflect the parameters of the human circulatory system. From this point of view, the formation mechanism of the radial artery in the circulatory system is a suitable method and approach for the objective study of pulse diagnosis. This paper summarizes the understanding of pulse mechanism in ancient and modern medicine from a multi-disciplinary perspective. It is the first time to systematically explain and analyze the mechanism of pulse formation from the perspective of biomechanics. The pulse wave, blood flow, vascular wall motion and boundary conditions are taken as the outline to interpret the mechanism of pulse formation, which provides new ideas and methods for the objectification of pulse diagnosis in traditional Chinese medicine.
