System for the extracorporeal elimination of carbon monoxide

A system for the extracorporeal elimination of carbon monoxide, comprising at least one pump and a gas exchange chamber which has an oxygen supply which is connected to an oxygen source via an oxygen supply line,

• wherein the at least one pump can be connected to the blood circulatory system of a person via a first tube section which can be connected to a cannula and is connected to the gas exchange chamber via a second tube section,
• wherein the system is arranged to perform a stepwise elimination of carbon monoxide via only one access to the blood circulatory system of the person by treating the blood portion by portion by repeatedly performing three operating modes,
• wherein the system is arranged to convey blood from the blood circulatory system of the person into the gas exchange chamber in a first operating mode and to convey blood from the gas exchange chamber back into the blood circulatory system of the person in a third operating mode, and
• wherein:
• a. the oxygen supply line comprises a first valve and a carbon monoxide discharge line of the gas exchange chamber comprises a second valve, each of which is controllable and by which the pressure within the gas exchange chamber and the flow of oxygen in the form of gas bubbles through the blood is controllable, and
• b. the system is configured, in a second operating mode, to contact blood in the gas exchange chamber with oxygen at a pressure elevated above atmospheric pressure, and
• c. in the second operating mode, a flow between the blood circulatory system of the person and the gas exchange chamber is preventable by a third valve in the first or second tube section or the at least one pump deactivated.
