Abstract
An oxygenation device for use with extracorporeal blood circulation is disclosed. The device includes an oxygenator housing having a blood inlet end cap having a blood inlet opening, a blood outlet end cap having a blood outlet opening, and a gas collector housing between the blood inlet opening and the blood outlet opening. The gas collector housing defines a gas compartment having a gas inlet chamber with a gas inlet port and a gas outlet chamber with a gas outlet port. Heating devices are disposed against the gas collector housing and include a first heating device in the gas inlet chamber and a second heating device in the gas outlet chamber. During operation of the oxygenation device, the heating devices heat the gas compartment.
