AN OXYGENATOR FOR OXYGENATING AN ORGANIC FLUID IN AN EXTRACORPOREAL CIRCUIT

摘要

The oxygenator (1 ) for oxygenating blood during extracorporeal circulation comprises: a box-like body (2) defining therein an oxygenation chamber (3) which has an inlet (7) for the organic fluid to be oxygenated and an outlet (8) for the oxygenated organic fluid; at least one oxygen exchanging unit (4) for exchanging oxygen with said organic fluid, which is arranged in said oxygenation chamber (3) and comprises at least two windings of hollow fibers (6) made from a hydrophobic and gas-permeable microporous membrane which are designed to be lapped by transverse flows of said fluid to be oxygenated and to have oxygen or a mixture of oxygen flowing therethrough, said oxygenator comprising at least one three-dimensional frame (9) which is designed to be accommodated in said oxygenation chamber (3) and defines at least two corresponding housing compartments (1 2) for accommodating said at least two windings (6) in peripherally compressed fashion.
