SYSTEM AND RESPIRATORY DEVICE FOR SUPPORTING POSITIVE PRESSURE IN PATIENTS' RESPIRATORY WAYS Russian patent published in 2014 - IPC A61M16/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. System for supporting positive pressure in patient's respiratory ways, when patient is breathing, contains respiratory device, made with possibility of controlling gas mixture flow between surrounding atmosphere and, at least, one external orifice of patient's respiratory ways. Respiratory device has first resistance to flow of gas mixture, flowing from surrounding atmosphere into patient's respiratory ways through respiratory device, and second resistance to flow of gas mixture, flowing from patient's respiratory ways into surrounding atmosphere through respiratory device. First resistance is less than second resistance, so that during inhalation gas mixture flows from surrounding atmosphere into patient's respiratory ways through respiratory device without delay. During exhalation second resistance of respiratory device to gas mixture, flowing from patient's respiratory ways into surrounding atmosphere, increases pressure inside patient's respiratory ways. Increased pressure supports patient's respiratory ways. Pressure generator is made with possibility to form flow of compressed respiratory mixture and providing additional support of patient's respiratory ways and is connected with case of respiratory device through contour, which gas mixture channel forms between respiratory device and pressure generator, by which flow of compressed respiratory mixture is supplied from pressure generator into patient's respiratory ways through respiratory device. First resistance constitutes less than approximately 0.025 cm of H₂O with flow consumption 30 l/min. Second version of system, which is different in constructive implementation, is disclosed.

EFFECT: providing treatment of sleeping disorders due to creation of resistance to exhalation.
