- 1A14 Computational Design and Assessment of a Miniature Axial Flow Blood Pump Placed at Aortic Root
抄録
A miniature axial flow blood pump that can be implanted at aortic root has been developed at Tokai University. In this study, a new impeller model for this axial flow pump was designed and the performance was numerically investigated. The pump has a rotor with three impeller blades. The span and axial length of the impeller blade are 1.15 mm and 13.9 mm, respectively. The inlet and outlet angles of each blade tip are 20.8° and 43.1°, respectively. The computational model of the pump placed in a tube with a diameter of 23 mm, which modeled an aortic root, was constructed and the blood flow was numerically calculated using a computational fluid dynamics (CFD) software. The pump performance predicted from the CFD results showed that the pump enables full support of left heart function at a rotational speed of 21000 rpm and that the partial support at 18000 rpm has potential to reduce the left ventricular load enough.
