医推拿和血液动力学

目的建立血液动力学模型研究解释中医推拿摆动类手法(gun法和振法)的机制。方法用脉动血流通过有轴向运动缓变狭窄血管的模型模拟（gun）法，控制血流的基本方程是Navier-Stokes方程．用组织压动态变化对毛细血管和组织物质交换产生影响的模型模拟振法．毛细血管血流服从Stokes方程。边界条件满足Starling定律，组织压随振法发生动态变化。结果实试（gun）法时，动脉血流速发生变化，平均血流量增加；实施振法时，毛细血管内血液表观粘度减少。结论以上结果可用以解释中医推拿摆动类手法(gun法和振法)的”活血化瘀”机制，

Chinese Traditional Medical Massage and Hemodynamics

Objective To present a hemodynamics model to explain the mechanism of Chinese Traditional Medical Massage (CTMM) Swing manipulation (Rolling manipulation and Vibrating manipulation). Methods Pulsatile blood flow through an artery with mild stenosis moving axially is studied for modeling Rolling manipulation. Blood flow is governed by Navier-Stokes equations. The effect of dynamical variation of tissue pressure on exchange between capillary and tissue is investigated for Vibrating manipulation. The governing equation of blood flow in capillary is Stocks equation with boundary condition of Starling law. The tissue hydraulic pressure changes with Vibrating manipulation. Results Blood velocities change and average flow rate through the artery increases for the rolling manipulation model ; and a reduction of blood apparent viscosity in capillary is showed for the Vibrating manipulation . Conclusion The results could be used to explain the hemodynamics principle of CTMM Swing manipulation : removing blood stasis and promoting blood circulation .
