- Estimation of Hemolysis within Continuous Flow Blood Pump by Computational Fluid Dynamics Analysis
抄録
The successful use of a continuous flow blood pump depends on the degree of blood trauma. A major cause of blood trauma is the mechanical stress acting on the corpuscles passing through the pump, hi this study, assuming that the red blood cells passed along the streamlines, a blood damage index was calculated based on the changes in shear stress with time along streamlines starting from entrance plane of the pump. Indices of hemolysis should be estimated by analysis under the same operating conditions (i.e. flow rate and pressure head) to compare the hemolysis levels of different pumps The preliminary analyses for deriving the rotational speed conditions obtaining 5L/min of flow rate and 100mmHg pressure head, and final analysis for estimating the hemolysis index were automated. This estimation method of hemolysis is a useful tool for design modification of blood pumps.
