Title:
軸受およびシールの無い血液ポンプ
Document Type and Number:
Japanese Patent JP3657010
Kind Code:
B2
Abstract:
A pump for transferring fragile and aggressive liquids such as human blood and comprising a pumping chamber along with a pair of fluid inlet ports arranged in oppositely disposed relationship on the chamber, and one or more outlet ports arranged transversely and medially of the inlet ports. A rotor is positioned within the pumping chamber having a dual-conical configuration converging toward opposed polar end regions and with an axis of rotation extending between the polar regions. The rotor includes magnets which are arranged at radially spaced locations and with a magnetic drive positioned to deliver rotational driving energy to the rotor. The sole support for the rotor are the hydrodynamic forces acting upon the rotor during its operation, with the rotor body having a relative density of between 10% and 90% of the relative density of the fluid being pumped.
