Abstract
A device for oxygenating blood in an extracorporeal circuit includes a first structure suitable to delimit a portion of space-containing capillaries made of microporous membrane. The capillaries convey oxygen and are wet externally by blood flowing through a portion of space between an intake connector, which is connected to a venous line of the extracorporeal circuit, and a delivery connector. The device includes a second structure monolithically connected and contiguous to the first structure. The second structure is suitable to contain blood filtration means that divide the portion of space delimited thereby into a blood distribution chamber, provided with an air vent and connected to the delivery connector of the first structure, and a blood collection chamber provided with a delivery connector connected to the arterial line of the extracorporeal circuit.
