Title (EN) SPEAKING VALVE ASSEMBLIES AND TRACHEOSTOMY TUBE ASSEMBLIES
(FR) ENSEMBLES VALVULES PHONIQUES ET ENSEMBLES TUBES DE TRACHÉOTOMIE
Abstract:
(EN) A speaking valve assembly (2, 200) for fitting to the machine end (13) of a tracheostomy tube (1) has a one-way valve (23, 236) that allows inhalation but prevents exhalation. The assembly further includes a pressure relief arrangement that remains closed during normal respiration and vocalisation but opens when pressure in the assembly rises above a normal level. In one arrangement the pressure relief arrangement takes the form of a ball valve (30) with a ball (32) that is lifted away from an opening (31) by excess pressure but falls back to block the opening when pressure reduces. An alternative pressure arrangement has a slidable collar (226) that normally covers vent apertures (223) in a housing (220) of the assembly. When pressure in the assembly rises above a normal level the collar (226) is pushed out to expose the vent apertures (223) and allow air to escape.
(FR) Cette invention concerne un ensemble valvule phonique (2, 200) se fixant côté machine (13) d'un tube de trachéotomie (1) comportant un clapet unidirectionnel (23, 236) qui permet l'inhalation mais empêche l'exhalation. L'ensemble comprend en outre un agencement de décharge de pression qui reste fermé pendant une respiration et vocalisation normales mais s'ouvre quand la pression dans l'ensemble s'élève au-dessus d'un niveau normal. Selon un agencement, l'agencement de décharge de pression se présente sous la forme d'un clapet à bille (30) contenant une bille (32) qui est soulevée pour découvrir une ouverture (31) sous l'effet d'un excès de pression mais retombe pour bloquer l'ouverture quand la pression diminue. Un autre agencement pour la pression comprend un collier coulissant (226) qui normalement recouvre des ouvertures d'aération (223) dans un boîtier (220) de l'ensemble. Lorsque la pression dans l'ensemble s'élève au-dessus d'un niveau normal, le collier (226) est poussé pour exposer les ouvertures d'aération (223) et permettre à l'air de s'échapper.
