ABSTRACT:
To supply oxygen to blood and control its carbon dioxide content, the blood is pumped through a silicone rubber tube wound as a helix around an aluminum cylinder. In a typical use, water at 37.degree. C. is pumped through the cylinder to maintain the temperature constant and a gas containing 95% oxygen and 5% carbon dioxide is passed over the silicone rubber tube so that: (1) oxygen passes through the rubber silicone tube to enrich the blood in oxygen; and (2) carbon dioxide is exchanged through the silicone rubber tube between the blood and the outside gas.
