Document Type and Number:
Japanese Patent JPH06509733
Kind Code:
A
Abstract:
An extracorporeal blood oxygenation device having a sealed casing containing a bundle comprised of a plurality of gas permeable tubes for efficient gas transfer. The bundle is woven from tubes having at least two different sizes, at least the smaller diameter tubes being gas permeable. The tubes are relatively non-thrombogenic and are open at each end to an enclosed annular chamber having attached input and output fittings. Oxygen-rich gas flows into one annular chamber through an input fitting before flowing through the gas permeable tubes. Venous blood to be oxygenated is introduced into the sealed casing directly into the center of the bundle for dispersement radially outward through the bundle and across the gas permeable tubes wherein the blood comes in contact with the membrane surface of the gas permeable tubes and exchanges carbon dioxide for oxygen across that surface before being collected from around the perimeter of the bundle for return to the patient.
