1A11 モノピボット遠心血液ポンプのインペラ形状に関する諸検討

Abstract

The impeller geometry of the centrifugal blood pump affects the pressure flow characteristics, the rotational characteristic of the impeller, and the hemocompatibility of the pump. Therefore, several geometrical parameters of the impeller were summarized, and the effect of those parameters on those pump characteristics were considered for better designed blood pump. The impeller diameter, the vane geometry, the shroud geometry, and the washing way about the bearing or the seal were considered. Also, the impeller geometry was reconsidered about the design adaptation to the monopivot centrifugal blood pump.
