Abstract
An oxygenator has a housing provided with a blood inlet and a blood outlet, a bundled aggregate of a multiplicity of gas-exchange membranes, and a gas inlet and a gas outlet independently formed outside opposite bundle end parts of the bundled membrane aggregate, the bundled membrane aggregate being stowed within the housing in such a manner as to partition a gas flow path for communication between the gas inlet and gas outlet and a blood flow path for communication between the blood inlet and blood outlet from each other, which oxygenator is characterized by the fact that the bundled membrane aggregate is provided in or near the gas outlet with a device for thermally insulating or heating the gas emanating from the gas outlet.
