Title
(EN) DEVICE AND METHOD FOR DEACTIVATING AIRBORNE PATHOGENS
(FR) DISPOSITIF ET PROCÉDÉ PERMETTANT DE DÉSACTIVER DES PATHOGÈNES EN SUSPENSION DANS L'AIR
Abstract
(EN) A breathing apparatus includes a first air pathway for receiving ambient air and channeling the air through a portion of the breathing apparatus, a heating section operatively coupled to the first air pathway and configured to elevate a temperature of the ambient air in the first air pathway to a first prescribed temperature, and a cooling section operatively coupled to the first air pathway and configured to reduce the temperature of the ambient air heated by the heating section to a second prescribed temperature, the second prescribed temperature lower than the first prescribed temperature. A breathing circuit is coupled to the first air pathway and configured to provide the cooled air to a user.
(FR) L'invention concerne un appareil respiratoire qui comprend un premier trajet d'air pour recevoir de l'air ambiant et pour canaliser l'air à travers une partie de l'appareil respiratoire, une section de chauffage couplée de manière fonctionnelle au premier trajet d'air et configurée pour élever une température de l'air ambiant dans le premier trajet d'air jusqu'à une première température prescrite, et une section de refroidissement couplée de manière fonctionnelle au premier trajet d'air et configurée pour réduire la température de l'air ambiant chauffé par la section de chauffage à une seconde température prescrite, la seconde température prescrite étant inférieure à la première température prescrite. Un circuit respiratoire est couplé au premier trajet d'air et configuré pour fournir l'air refroidi à un utilisateur.
