Title (EN) AIRWAY CLEARANCE SYSTEM
(FR) SYSTÈME DE DÉGAGEMENT DES VOIES RESPIRATOIRES
Abstract:
(EN) An airway clearance system includes a bladder, a negative pressure relief valve, a positive pressure relief valve, and a port. The bladder is moveable between an expanded state and a compressed state, and defines a first volume in the expanded state and a second volume in the compressed state. The second volume is less than the first volume. The negative pressure relief valve is in fluid communication with the bladder and configured to supply fluid to the bladder from an atmosphere surrounding the bladder. The positive pressure relief valve is in fluid communication with the bladder and configured to supply fluid to the atmosphere from the bladder. The port is in fluid communication with the bladder and configured to supply fluid from the bladder when the bladder moves to the compressed state and to supply fluid to the bladder when the bladder moves to the expanded state.
(FR) Un système de dégagement des voies respiratoires comprend une vessie, une soupape de dépression, une soupape de surpression, et un orifice. La vessie est mobile entre un état dilaté et un état comprimé, et définit un premier volume à l'état dilaté et un second volume à l'état comprimé. Le second volume est inférieur au premier volume. La soupape de dépression est en communication fluidique avec la vessie et configurée pour fournir un fluide à la vessie à partir d'une atmosphère entourant la vessie. La soupape de surpression est en communication fluidique avec la vessie et configurée pour fournir un fluide à l'atmosphère à partir de la vessie. L'orifice est en communication fluidique avec la vessie et configuré pour fournir du fluide à partir de la vessie lorsque la vessie se déplace vers l'état comprimé et pour fournir un fluide à la vessie lorsque la vessie se déplace vers l'état dilaté.
