Embodiment Construction

[0045] figure 1 The oxygenator 1 shown in has a blood inlet 2 and a blood outlet 3 . For supplying gas, a gas inlet 4 and a gas outlet 5 are provided. In the heat exchanger, hollow fibers through which water passes are arranged in the radially inner region, and semipermeable hollow fibers through which gas passes are arranged in the radially outer region. Thus, heating by means of water entering at the water inlet 8 and leaving at the water outlet 9 takes place radially inside, whereas in the radially outside region 7 gas exchange takes place. For a more detailed explanation of this type of oxygenator, reference is made to EP 765 683 B1.

[0046] exist figure 2 In the oxygenator shown schematically in , the main design is substantially retained and the water inlet 8, water outlet 9 and hollow fibers through which water passes are omitted. The oxygenator 10 has a housing wall 11 which surrounds a housing chamber 12 . Such as figure 1 As shown in , this housing chamber 12...

Abstract

The present invention relates to an oxygenator having a housing wall defining a housing chamber with a blood inlet and a blood outlet, a gas inlet and a gas outlet, and the oxygenator also has a heating element, the The heating element is disposed in the oxygenator between the blood inlet and the blood outlet to control the temperature of blood flowing through the housing chamber. The oxygenator also includes electrical connections, and the heating element has a resistor designed as a wire. The invention also relates to a method for controlling heat emission at a heating element of an oxygenator by measuring the flow of blood through said oxygenator and the power of a pump influencing said flow and adjusting the heating power accordingly.

Description

technical field [0001] The present invention relates to an oxygenator having a housing wall defining a housing chamber having a blood inlet, a blood outlet, a gas inlet and a gas outlet, and having a heating element, the A heating element is disposed in the oxygenator between the blood inlet and blood outlet to control the temperature of blood flowing through the housing chamber. Background technique [0002] Oxygenators are medical gas exchangers primarily used during cardiopulmonary therapy lasting several days or during surgery. Another application is eg dialysis. In addition to gas exchange, these oxygenators generally also offer the possibility to control the temperature of the blood flowing through the housing chamber of the oxygenator. The blood is typically heated in the oxygenator because the temperature of the blood in the extracorporeal circuit (ie, outside the patient's body) decreases over time and lowers the patient's body temperature. In addition to this he...
