DEVICE FOR SATURATION OF BLOOD WITH OXYGEN

摘要

An oxygenator primarily for human blood has a stator with a cavity partly defined by a first substantially flat wall and a peripheral wall and has a rotor with a second substantially flat wall facing the first wall. On their facing sides both walls have supports highly permeable to gas. Both supports are covered by gas-permeable, hydrophobic membranes between them defining a passage for liquid extending from near the center of the cavity to near the peripheral wall. Gas is conducted through the supports and membranes on the stator and on the rotor. Blood is supplied through the stator to the cavity near the center thereof and, without an external pump, is impelled to flow through the passage and out an outlet in the peripheral wall, the membranes having irregularities or vanes acting as centrifugal impellers.
