HOLLOW YARN MEMBRANE TYPE ARTIFICIAL LUNG
Document Type and Number:
Japanese Patent JPS60193469
Kind Code:
A
Abstract:
A blood oxygenator comprising a housing generally in the form of a box and bundles of hollow fibers of semipermeable membrane set therein for effecting gas exchange therethrough. In this blood oxygenator, each end of each bundle of hollow fibers of semipermeable membrane is secured together by potting material in such a way as to allow their open ends to communicate separately with a gas inlet and a gas outlet; the space around the bundles of hollow fibers of semipermeable membrane communicates with a blood inlet and a blood outlet; the blood-gas contact chamber within the housing is divided into a plurality of compartments with the interposition of blood flow channels narrowed by baffles; and the bundle of hollow fibers of semipermeable membrane is disposed in the contact chamber so as to be substantially parallel to the baffles. This blood oxygenator has high oxygen and carbon dioxide exchange rates per unit area of membrane, causes little channeling of the blood and gas, exhibits only a small pressure loss in the flow of blood, and is easy to manufacture.
