Title
(EN) AIR MANAGEMENT DEVICE FOR DIALYSIS MACHINES
(FR) DISPOSITIF DE GESTION DE L’AIR POUR MACHINES DE DIALYSE
Abstract
(EN)
A dialysis system may include a dialysis machine (e.g., a peritoneal dialysis machine or a hemodialysis machine) for transferring a liquid to a patient via tubing. The dialysis system may include an air management device for filtering out air content from the liquid prior to transferring to the patient. The air management device may be a connector cap for use in a peritoneal dialysis system during a priming process. Alternatively, the air management device may be a drip chamber for use in a hemodialysis system. The air management device may include a vent. In addition, the air management device may include a movable element for sealing the vent. In addition, and/or alternatively, the air management device may include a reservoir for receiving an overflow of liquid.
(FR)
La présente invention concerne un système de dialyse qui peut comprendre une machine de dialyse (par exemple une machine de dialyse péritonéale ou une machine d’hémodialyse) pour transférer un liquide vers un patient par l’intermédiaire d’une tubulure. Le système de dialyse peut comprendre un dispositif de gestion de l’air pour filtrer à l’extérieur le contenu d’air du liquide avant le transfert au patient. Le dispositif de gestion de l’air peut être un capuchon de connecteur pour l’utilisation dans un système de dialyse péritonéale pendant un processus d’amorçage. En variante, le dispositif de gestion de l'’air peut être une chambre de goutte-à-goutte pour l’utilisation dans un système d’hémodialyse. Le dispositif de gestion de l’air peut comprendre un orifice de ventilation. De plus, le dispositif de gestion de l’air peut comprendre un élément mobile pour fermer hermétiquement l’orifice de ventilation. De plus, et/ou en variante, le dispositif de gestion de l’air peut comprendre un réservoir de réception d'un trop-plein de liquide.
