METHOD FOR DETERMINING ABSOLUTE AND EFFECTIVE BLOOD VISCOSITY

摘要

A method is provided for detecting interactions in the circulating blood of a living being caused by external factors by analyzing the viscosity of the living being's circulating blood. The method utilizes a viscosity measuring system that monitors the change in height (h1, h2) of two, oppositely-moving, columns of blood (r1, r2) from the circulating blood and, given the dimensions of a capillary tube (52) through which the blood flows, determines the viscosity over a range of shear rates. Two viscosity profiles are generated over different shear rate ranges. The method utilizes the relationship of these two viscosity profiles to detect the interactions in the circulating blood of a living being caused by the external factors. The blood columns can then be pivoted clockwise for measuring platelet aggregation and red blood cell deformability. A method/apparatus for determining the yield stress of blood is discussed. Also, a method for determining the effects of drugs designed to treat a condition of the living being is discussed.
