Title
(EN) HUMIDIFIER WITH INGRESS PROTECTION FOR USE IN CPAP THERAPY
(FR) HUMIDIFICATEUR AVEC PROTECTION D'ENTRÉE DESTINÉ À ÊTRE UTILISÉ DANS UNE THÉRAPIE CPAP
Abstract
(EN)
An apparatus for use in humidifying a flow of treatment gas for a user includes: a housing; an inlet structured to receive the flow of treatment gas from a gas flow generator; an outlet structured to convey the flow of treatment gas to a patient interface device; a compartment defined in the housing, the compartment being structured to hold a volume of water therein; a primary valve disposed between the inlet and the compartment, the primary valve being structured to permit passage of the flow of treatment gas from the inlet to the compartment and to prevent passage of a fluid from the compartment to the inlet; and a secondary valve disposed between the compartment and the inlet which is structured to permit passage of a fluid from the compartment to the inlet and to prevent passage of the flow of treatment gas from the inlet to the compartment.

La présente invention concerne un appareil destiné à être utilisé pour humidifier un flux de gaz de traitement pour un utilisateur qui comprend : un boîtier ; une entrée structurée pour recevoir le flux de gaz de traitement provenant d'un générateur de flux de gaz ; une sortie structurée pour transporter le flux de gaz de traitement vers un dispositif d'interface patient ; un compartiment défini dans le boîtier, le compartiment étant structuré pour contenir un volume d'eau à l'intérieur de celui-ci ; une vanne primaire disposée entre l'entrée et le compartiment, la vanne primaire étant structurée pour permettre le passage du flux de gaz de traitement depuis l'entrée vers le compartiment et pour empêcher le passage d'un fluide du compartiment à l'entrée ; et une vanne secondaire disposée entre le compartiment et l'entrée qui est structurée pour permettre le passage d'un fluide du compartiment à l'entrée et pour empêcher le passage du flux de gaz de traitement de l'entrée au compartiment.
