It is important to clarify the relationship between the hemolysis and degree/area of surface roughness under blood shear fields. From our previous study using a rotational shear stressor, we have obtained that the increasing hemolysis was related to the increasing shear stress due to the surface roughness. However we have not yet measured the increasing shear stress amount with the stressor. In this study, we tried to quantify the shear stress level using 6.8 times higher viscous test blood with dextran solution in order to detect the increasing shear stress effectively using a torque sensor of the stressor. As a result, hemolysis caused by surface roughness under shear flow field did not depend on the homogeneously increasing shear stress, but on fluid environment near the surface roughness.
