Abstract

769,786. Blood oxygenating apparatus. SVENSKA AKTIEBOLAGET GASACCUMULATOR. June 6, 1955 [June 4, 1954], No. 16176/55. Class 81(2) Blood oxygenating apparatus comprises a rotatable cylinder of perforate material, on the surface of which the blood is spread in the presence of an oxygen-containing gas. Blood is received from the patient through a tube 1 and passes over a porous tube 14 through which oxygen is forced from a tube 12. Bubbles of excess oxygen and any foam generated are removed in a filter 3 of wool or chips of an inert plastic and the blood passes into the lower part of a container 5 in which a cylinder 6 of perforated plastic material is rotated, so that the blood is carried over its surface. The container 5 may be supplied with a mixture of oxygen and nitrous oxide, the latter serving to assist the absorption of oxygen by the blood. Finally the blood passes through a filter 7. similar to the filter 3, and is returned to the body, through tube 10, by a pump 9. By means of a valve 13, controlled by a pressure-responsive diaphragm 16, the rate of supply of oxygen may be determined by the rate of flow of blood around the apparatus.
