ドップラーOCTを用いた振動平板流れにおける高分子血液モデルの流動特性

Biological and macromolecular flows are multilayered flows, and microcirculation exhibits complex flow characteristics due to erythrocyte deformation. In addition, erythrocyte deformability is reduced by various diseases. A method for evaluating erythrocyte deformability is to image the shape change from the viscous stress generated by the velocity gradient between two walls of a vibrating plate. The purpose of this study is to tomographically detect flow characteristics using Doppler Optical Coherence Tomography. The velocity distribution between the oscillating plates was tomographically visualized for a flow with a blood cell concentration equivalent to that of a living body. The results showed that the shear velocity decreased as the shear rate increased, and the shear velocity was visualized as a shear-slicing behavior.
