Abstract
A membrane blood oxygenator-blood heat exchanger combination including a gas exchange section of multi-layer structure having alternate layers of rectangular polymer membranes and rectangular mesh spacers forming alternate gas channels and gas exchange blood channels between the membranes, said gas and blood channels being generally perpendicular to each other; a heat exchange section having a multi-layer structure having alternate layers of metal sheets and rectangular mesh spacers forming alternate heat exchange blood channels and water channels, said blood and water channels being perpendicular to each other, said heat exchange blood channels being an extension of the gas exchange blood channels and having equal blood flow sectional area to said gas exchange blood channels.
