APPARATUS AND METHOD FOR EXTRACORPOREAL BLOOD OXYGENATION.

摘要

the device (10) for extracorporeal oxygenation of blood with a hermetically sealed housing (12) containing a beam composed of a plurality of gas permeable tubes (42), which allows for an efficient transfer of gas. the tube bundle is woven from at least two different sizes, at least the smaller diameter tubes being gas permeable.the tubes (42) are relatively non thrombogenic and are open at each end to a closed annular chamber (56, 58) which are attached to inlet and outlet connections (18, 20, 22, 24). the oxygen rich gas flows into an annular chamber (56) through an inlet connection (20) to flow through the gas permeable tubes (42).we introduced the blood veins to ventilate in the airtight housing, directly in the center of the beam, in order to have a radial beam through the external separation and the gas permeable tubes (42), in which the blood comes in contact with the surface of a member a tube (42) is gas permeable.and the exchange of carbon dioxide with oxygen in the surface, to be collected around the perimeter of the beam in order to return to the patient.
