摘要： 为探索中医脉象的形成与人体循环系统及血管生理参数之间的联系,在心血管双弹性腔模型基础上,借助Simulink仿真外周阻力、血管顺应性、血液流动惯性变化对脉波图时域特性的影响规律,并利用中医脉象模拟系统,通过改变血液粘度、血管弹性、外周阻力及取脉压力,实测和验证Simulink仿真结果,建立心血管生理参数与理论模型之间的联系。实验结果表明,血液粘度变化对外周血管阻力有一定影响,血管弹性与顺应性直接相关,同时脉诊的取脉过程也会对血液惯性造成影响,继而改变输出波形。该成果为中医脉诊在动脉硬化、高血粘等疾病早期客观化诊断领域提供了理论支持。

Abstract: In order to explore the relationship between formation of pulse condition and body’s vascular physiological parameters,which is based on models of cardiovascular dual elastic Chambers,this paper takes advantage of Simulink to simulate the influences of peripheral resistance,arterial compliance and the inertia flow of blood on the pulse wave graph’s time-domain features.With the traditional Chinese medicine pulse simulation system,a simulation experiment,which changes blood viscosity,vascular elasticity,peripheral resistance and pressure to gain pulse,is further designed to test and verify Simulink results and also establishes a connection between the physiological parameter and the theoretical model.The study shows that the change of blood viscosity has an effect on peripheral resistance and the vascular elasticity is closely related to arterial compliance.Meanwhile,the pulse-taken process has an effect on output waveform which means it is related to the inertia flow of blood.The research results provide theoretical support for TCM early objective diagnosis of diseases such as arteriosclerosis and hyper viscosity of blood.
