法推拿形成运动狭窄血管内血液流量分析

FLUX ANALYSIS OF AN ARTERY WITH A MOVING STENOSIS FORCED BY ROLLING MANIPULATION

目的 研究中医(扌衮)法推拿活血化淤,促进血液循环的血液动力学机制。方法 研究中医(扌衮)法推拿形成的运动狭窄血管内的血液动力学。通过数值求解线化的Navier-Stokes方程,讨论不同的作用力水平渗透系数、不同的最大狭窄度以及不同的手法频率对血液流量影响。结果 较大的水平渗透系数、较快的手法频率和较小的最大狭窄度将使得血液流量的增加。结论 (扌衮)法推拿增大动脉血流量是多种因素共同作用的结果,这与正确的(扌衮)法推拿手法可以促进血液循环相吻合。

Objective Investigate the hemodynamical mechanism that rolling manipulation can promote blood circulation. Methods Hemodynamics in an artery with a moving stenosis forced by rolling manipulation has been investigated. By solving linearized N - S equations, varies of factors contributing to the flow rate have been discussed, including different Horizontal Penetration Parameters, different Maximal Stenosis Degrees and different Manipulation Frequencies. Results Larger Horizontal Penetration Parameter, faster Manipulation Frequency and smaller Maximal Stenosis Degree will make the flow increase. Conclusion The promition of the arterial blood flow rate by rolling manipulation depends on seceral factors, it agrees with the fact that appropriate rolling manipulation can promote blood circulation.
