Abstract

As a fundamental equipment for studying blood flow in microcirculation, the inclined centrifuge microscope enables us to measure frictional characteristics of cells moving on a plate in a medium under the effect of inclined centrifugal force. Specifically, this paper deals with measurement for red blood cells moving on a glass plate in plasma. First, accuracy of the manual measurement of cell velocity through the microscope was confirmed in comparison with the image processing method. Measurement was then performed confirming frictional characteristics of red blood cells were properly modeled as the sum of the Coulomb friction with friction coefficient of 0.206 and the linear viscous friction applied on a simplified circular disk with a plasma layer of thickness of 0.176 μm in the present condition.
