ABSTRACT:
The oxygenator is used for arterializing blood during open heart surgery. The oxygenator is factory-assembled and sterilized and is of economic and efficient design so that it can serve as a throwaway unit. Blood from the patient is oxygenated as it passes through the center of a tubular sparger with porous walls which supplies oxygen bubbles of the optimum size. The foaming blood is delivered to the top of the main oxygenator body where it is distributed by gravity flow downward across the heat exchanger tubing. The heat exchanger is wound as a flat coil with all connections outside of the oxygenator body. A silicone-coated sponge is located below the heat exchanger so that downwardly flowing foaming blood is defoamed as it passes through the sponge. Carbon dioxide and other gases are vented, and liquid blood gravitates into a tapered arterial reservoir.
