A blood oxygenator is provided with a preformed defoaming member of open-cell sponge material of synthetic plastic disposed in the defoaming chamber in series between the oxygenating chamber and the blood reservoir chamber of the oxygenator. Spaces are provided between the defoaming member and the upper and lower walls of the defoaming chamber to produce a reduced resistance to the flow of gas and blood. A fine mesh filter and funnel are connected to the defoaming chamber to gently transfer and filter blood flowing to the reservoir.
