| Outline of Final Research Achievements |
Centrifugal blood pumps with a magnetic bearing system have many advantages such as, 1)low hemolysis; the gaps between pump housing and impeller can be controlled so that, grinding down of erythrocytes can be minimized, 2)high durability of pump elements; without wearing of bearing and/or shaft, 3)antithrombogenicity; shear stresses of platelets can be controlled.
In this study, we developed a miniature centrifugal blood pump which has non-contact magnetic bearing system for the aim to apply to pediatric mechanical circulatory support.In order to assist the pediatric blood circulation, the prototype pump had an impeller diameter of 48 mm with 6 straight banes, and the inner diameter of pump housing was 49 mm. The impeller was supported with a 2 degree of freedom magnetic bearing system and was magnetically coupled to the external motor driver.The fluid dynamic performances and hemocompatibility of the pump was evaluated comparing with contact bearing type pump and clinically used pump.
