ABSTRACT:
A blood oxygenator of the outside perfusion type using hollow fibers as the gas exchange membrane. In this blood oxygenator, a plurality of contact chambers each containing a bundle or bundles of hollow fibers for gas exchange use and communicating with a blood inlet and a blood outlet are disposed to make blood flow in multiple paths within a housing, and each bundle of hollow fibers is arranged so as to be substantially perpendicular to the direction of blood flow. In spite of its compact construction, this blood oxygenator has high oxygen and carbon dioxide exchange rates per unit of membrane even when used in the gas exchange of blood having high flow rate, exhibits only a small pressure loss, and causes little channeling of the blood and gas. Moreover, it is easy to manufacture because of its relatively simple structure.
