Problems solved by technology

[0006] A problem associated with ECLA therapy is that in order to generate adequate blood flow through the ECLA device, large blood vessels (veins and arteries) need to be cannulated and large catheters and tubes are required to transport the blood

Embodiment Construction

[0043] It is generally assumed that the patient's respiratory drive is primarily based on the CO2 content in the patient's blood, which in turn depends on the patient's alveolar ventilation and any extracorporeal removal of carbon dioxide from the patient's blood. Relying on this assumption, the present disclosure proposes the use of bioelectrical signals indicative of the patient's respiratory drive to control the operation of the ECLA device and thus the degree of extracorporeal removal of CO2 achieved by the ECLA device.

[0044] figure 1 A first exemplary embodiment of a system 1 for removing CO2 from the blood of a patient 3 is shown. System 1 is typically an intensive care system used to treat critically ill patients.

[0045] The system 1 includes a medical device 5, referred to herein as an extracorporeal lung assist (ECLA) device, for providing ECLA therapy to a patient 3 by performing extracorporeal removal of CO2 from the patient's blood. In some embodiments, the ...

Abstract

The present disclosure relates to a system (1) for carbon dioxide [CO<2>] removal from the circulatory system of a patient (3), comprising a medical device (5) for providing extracorporeal lung assist[ECLA] treatment to the patient (3) through extracorporeal removal of CO<2> from the patient's blood, at least one control unit (22A-22C) for controlling the operation of the medical device (5) so asto control a degree of CO<2> removal obtained by the ECLA treatment, and a bioelectric sensor (7) for detecting a bioelectric signal indicative of the patient's efforts to breathe. The at least one control unit (22A-22C) is configured to control the operation of the medical device (5) based on the detected bioelectric signal.

Description

technical field [0001] The present invention relates to the field of intensive care equipment for oxygenation of blood and removal of carbon dioxide (CO2) in critically ill patients. In particular, the present invention relates to a medical device for providing extracorporeal lung assist (ECLA) therapy to a patient by extracorporeal removal of CO2 from the patient's blood, and to a system comprising such a medical device. The invention also relates to a method for the extracorporeal removal of CO2 from the blood of a patient. Background technique [0002] Ventilators and medical devices for the extracorporeal removal of CO2 from human blood are well known examples of critical care equipment used to provide ventilation and sometimes circulatory support to patients with reduced lung function. [0003] Ventilators are used to provide respiratory therapy to a patient by supplying breathing gases containing oxygen to the patient's lungs, thereby allowing CO2 to be removed from a...
