Method of measuring the fluidity of liquids for medical and pharmaceutical purposes, and apparatus for performing the method

摘要

A method and apparatus for determining the fluidity of a liquid such as blood or serum having the steps of drawing the liquid from the source through a capillary tube measuring cell into a reservoir unit and returning the liquid back through the tube at a constant flow velocity while measurements are made. The pressure difference between the ends of the capillary tube are directly related to the viscosity of the liquid.
