The invention relates to an oxygenator with a housing wall, defining a housing chamber with a blood inlet and a blood outlet, a gas inlet and a gas outlet, and also with a heating element which is arranged in the oxygenator between the blood inlet and blood outlet in order to control the temperature of the blood flowing through the housing chamber. The oxygenator also comprises an electric connection and the heating element has an electric resistor which is designed as a wire. The invention also relates to a method for controlling the heat emission at the heating element of an oxygenator by measuring the flow of blood through the oxygenator and the power of a pump influencing the flow, with the heating power being adjusted in accordance therewith.
1-28. (canceled)
An oxygenator (10) with a housing wall (11), defining a housing chamber (12) with a blood inlet (2), a blood outlet (3), a gas inlet (4) and a gas outlet (5), a heating element (13) which has an electric resistor (14) and is arranged in the oxygenator between the blood inlet (2) and blood outlet (3) in order to control the temperature of the blood flowing through the housing chamber (12), an electric connection (15, 16) and a temperature control device (25), wherein the heating element (13) delivers a different heating power at different locations in the housing chamber (12).
A method for controlling the heat emission at a heating element (13) of an oxygenator (10), in which the flow rate of blood through the oxygenator (10) or the power of a pump influencing the flow rate are measured and the heating power is adjusted on this basis.
