Blood oxygenator of the membrane type in which a semi-permeable membrane (by which is meant a membrane that is permeable to gas but not to aqueous liquid) separates the blood from the oxygen but allows diffusion of oxygen into the blood and of carbon dioxide from the blood into the stream of gas; such blood oxygenator being characterized by a plurality of oxygen, water and blood units, each blood unit having a frame which together with semi-permeable membranes forms a blood cavity, the blood entering each such unit from one side, crossing the blood cavity and exiting on the other side, such blood units being isolated from the water units such that leakage of water into the blood units is precluded. Also applicable to oxygenators in which membranes of blood units are permeable to water and small molecules but not to large molecules or particles of the blood. |
