3637 Conical Spiral Groove Bearingを持つ血液ポンプの研究(G05-4 流体機械・医療機器,G05 流体工学)  [in Japanese] 3637 Study of Centrifugal Blood Pump using Conical Spiral Groove Bearings  [in Japanese]

A hydro dynamic centrifugal blood pump was developed using a Conical Spiral Groove Bearing (CSGB) is developed, whose geometry was determined based on a preliminary test. As the result of the preliminary test for the optimum groove shape, groove depth and number ware set to be 210μm, and 10, respectively. The performance test of the pump with CSGB showed the pump head H=2.5m (180mmHg) and flow rate Q=3.5L/min at rotational speed 3000 min^<-1>.
