摘要
本工作建立了组织压动态变化对毛细血管－组织交换影响的模型，数值计算了由于组织压动态变化时的渗透率ＦＲ，渗透因子ＦＦ和毛细血管内血液表观粘度μ，并和静态组织压情况进行了比较。结果表明由于组织压动态变化，使得这些重要的血液动力学参数均随之发生动态变化。在一般静态情况下，血液表观粘度将沿毛细血管增加，并保持在一个较高值。而在动态情况下，只要组织压动态变化幅度适当，那么在一定的时相内，血液表观粘度保持在一个较低值不再升高。这是中医推拿滚法和振法活血化瘀血液动力学机制的一个合理解释。
A model of effect of dynamical variation of tissue pressure on exchange between capillary and tissue has been presented in this paper. Filtration rate FR filtration factor FF and apparent viscosity μ of blood in capillary were got by using numerical calculation and compared with those in static condition. The results showed these important parameters varied dynamically with dynamical variation of tissue pressure. In general static condition blood apparent viscosity will increase along capillary tube then keeps in a higher level but in dynamic condition blood apparent viscosity will keep in a lower level not rise during some phase just if amplitude of dynamical variation of tissue pressure is in a suitable range. This is a reasonable explanation for Hemodynamics Mechanism of Chinese massage 'huoxuehuayu'.
