It is important to clarify the relationship between the hemolysis and degree 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 due to a problem of its torque sensor sensitivity. In this study, we used a cone-cylinder type rheometer with a highly sensitive torque sensor, and 3-time higher viscous test blood, assuming the increasing shear stress generation related to the roughness. As a result, higher torque was obtained for the viscous test blood, therefore, we consider that this rheometer can measure the torque value due to the surface roughness, which cause hemolysis under shear fields.
