Title (EN) RESPIRATORY HUMIDIFICATION SYSTEM
(FR) SYSTÈME D'HUMIDIFICATION RESPIRATOIRE
Abstract:
(EN) A system provides warm, humidified gas to a patient via a patient interface. Horizontal connections can be used between the humidification chamber and conduit. To reduce the likelihood of condensate flowing back to the humidification chamber, or dead space or gases recirculation regions occurring within the gases flow path, a raised portion is positioned inside of the flow path to improve flow characteristics and to provide a barrier for condensate back flow. The raised portion also reduces the amount of condensate that is formed in the system and provides better flow characteristics for sensing purposes.
(FR) L'invention concerne un système administrant un gaz chaud, humidifié à un patient par l'intermédiaire d'une interface de patient. Des liaisons horizontales peuvent être utilisées entre la chambre d'humidification et le conduit. En vue de réduire la probabilité d'un écoulement en retour de condensat vers la chambre d'humidification ou de la création d'un espace mort ou de régions de recirculation de gaz dans le trajet d'écoulement des gaz, une partie relevée est disposée à l'intérieur du trajet d'écoulement pour améliorer les caractéristiques d'écoulement et pour fournir une barrière contre l'écoulement en retour de condensat. La partie relevée réduit également la quantité de condensat qui est formée dans le système et fournit de meilleures caractéristiques d'écoulement à des fins de détection.
