Title
(EN) MOUTHPIECE AND NEBULIZER HAVING A MOUTHPIECE
(FR) EMBOUT BUCCAL ET NÉBULISEUR COMPRENANT UN EMBOUT BUCCAL
Abstract
(EN)
The present disclosure relates to a mouthpiece (40) for delivering an aerosol supplied by a nebulizer (100) to a user, the mouthpiece (40) comprising a body (46) defining a fluid path (47) from an inlet port (41) connectable to the nebulizer (100) to an inhalation opening (42) to be received in the mouth of a user and a filter (30). The filter (30) has a filter base (31) in fluid communication with the fluid path (47), a filter top (33) detachably connected to the filter base (31) and a filter material (32) provided between the filter base (31) and the filter top (33). The filter top (33) has an exhalation opening (36) cooperating with a one-way valve (39) allowing exhaustion of fluid from the fluid path (47) through the filter material (32) to the outside of the mouthpiece upon exhalation of a patient through the inhalation opening (42). The body (46) and the filter base (31) are an integrated one-piece unit so as to provide for an easy to handle and comfortable mouthpiece (40).
(FR)
La présente invention concerne un embout buccal (40) pour administrer un aérosol fourni par un nébuliseur (100) à un·e utilisateur·trice, l’embout buccal (40) comprenant un corps (46) définissant un trajet de liquide (47) d'un orifice d’entrée (41) pouvant être relié au nébuliseur (100) à une ouverture d’inhalation (42) à recevoir dans la bouche d’un·e utilisateur·trice et un filtre (30). Le filtre (30) présente une base de filtre (31) en communication fluidique avec le trajet de liquide (47), un sommet de filtre (33) relié de manière détachable à la base de filtre (31) et un matériau de filtre (32) disposé entre la base de filtre (31) et le sommet de filtre (33). Le sommet de filtre (33) présente une ouverture d’expiration (36) coopérant avec une valve unidirectionnelle (39) permettant l’échappement de liquide depuis le trajet de liquide (47) à travers le matériau de filtre (32) vers l’extérieur de l’embout buccal lors de l’expiration d’un·e patient·e à travers l’ouverture d’inhalation (42). Le corps (46) et la base de filtre (31) se trouvent dans une unité monobloc intégrée afin de fournir un embout buccal (40) facile à manipuler et confortable.
