A respiratory valve device that adaptively adjusts resistance based on secretion status

Abstract

The application discloses a respiratory valve device capable of adaptively adjusting resistance based on secretion state, and relates to the technical field of medical respiratory valves.The application comprises a respiratory valve body, the bottom of which is connected with a liquid discharge pipeline, the liquid discharge pipeline is provided with an anti-backflow component, the bottom is fixed with a fixing disc, the bottom of the fixing disc is rotationally connected with a conversion disc, and a collecting bottle is detachably installed in a plurality of installation grooves in the bottom of the conversion disc; the conversion disc is driven to rotate by a worm and a worm wheel, and an internal flow guide channel is provided and penetrates the collecting bottle; the anti-backflow component comprises a fixing rod, a lifting plate, a first elastic member and a conical valve core, and can realize automatic opening and closing of the anti-backflow function; a guide rail component is arranged between the fixing disc and the conversion disc; and the collecting component realizes elastic locking and electrically-controlled unlocking through a limiting block, a second elastic member, an electromagnetic plate and a permanent magnet plate. The application can realize online rotation of the collecting container under a continuous ventilation state, avoid interruption of ventilation and invasion of pollutants, prevent backflow of secretions, and is convenient to disassemble and assemble and reliable in positioning.
