The present invention provides a respiratory device (1) for treating snoring comprising a main body portion (3) configured to enclose at least one external orifice of a patients upper airway to form an enclosed space communicating with the patients upper airway a check valve (7) disposed at the main body portion to allow a flow of inhaled gas to flow into the enclosed space and block a flow of exhaled gas from discharging out of the enclosed space an adjustable flow resistor (9) disposed at the main body portion to resist variably the flow of exhaled gas depending on an amplitude of the patients snoring a sensor unit (11) disposed at the main body portion and a control unit (13) disposed at the main body portion, the control unit being in electrical communication with the adjustable flow resistor and the sensor unit wherein the sensor unit is configured to detect a real-time pressure within the enclosed space, the control unit determines if the real-time pressure exceeds a preset pressure threshold and controls the adjustable flow resistor to reduce the flow resistance to the flow of exhaled gas if the real-time pressure exceeds the preset pressure threshold. The respiratory device according to the present invention may prevent an excess pressure from being accumulated in the respiratory device.La présente invention concerne un dispositif respiratoire (1) pour traiter un ronflement, comprenant une partie corps principal (3) configurée pour enfermer au moins un orifice externe des voies aériennes supérieures dun patient de façon à former un espace fermé communiquant avec les voies aériennes supérieures du patient un clapet de non-retour (7) disposé sur la partie corps principal pour permettre à un écoulement de gaz inhalé dentrer dans lespace fermé, et pour empêcher un écoulement de gaz expiré de sortir de lespace fermé une résistance à lécoulement ajustable (9) disposée sur la partie corps principal pour résister de façon variable à lécoulement de gaz expiré en fo
