VALVING RESPIRATORY GAS PATHWAY WITH CATHETER BALLOON Russian patent published in 2016 - IPC A61M16/20 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to medical equipment. Respiratory valve device comprises a catheter balloon, configured for being disposed in a respiratory gas pathway and valving said respiratory gas pathway so that said catheter balloon occludes said respiratory gas pathway when inflated allows air flow through said respiratory gas pathway when deflated. Connector comprises nozzle. Catheter balloon is disposed around said connector and said nozzle, and is sealed by fluid relative to said connector with help of a bushing. Base is configured to be arranged above said catheter balloon inside said respiratory gas pathway. Connector protrudes from said base. Pumping of said catheter balloon is performed by air flow, fed via said gas connection, said connector base, said connector and leaving nozzle. Connector base has an aerodynamic shape so that when air flow passes through said respiratory gas pathway in said direction from bushing towards said base and through it, said connector base provides low resistance to said air flow. Disclosed is a respiratory system including a valve, and a method valving a respiratory system.

EFFECT: technical result is providing valving by means of a catheter balloon.
