Abstract

The disposable oxygenator is for use in an extracorporeal blood circuit and provides for blood from the patient to be oxygenated as it passes through the centre of a tubular sparger (22) 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 heat exchanger tubing (40). The heat exchanger is wound as a flat coil with all connections outside of the oxygenator body. A silicone-coated sponge (54) 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 (82).
