Abstract

La présente invention décrit un dispositif d'interface nasale sans sangles. Le dispositif est utilisé en association avec un dispositif de pression positive continue, un BIPAP, des ventilateurs ou tout autre dispositif approprié. Le dispositif comprend un corps doté d'un passage vers un tube de ventilation, de trous d'expiration, et d'un passage vers les tubes d'interface de narine. Les tubes d'interface de narine comprennent un élément d'interface nasale en matériau extensible et compressible de telle sorte que l'utilisateur peut comprimer l'élément, l'insérer dans l'extrémité de la narine et lui permettre de s'étendre pour maintenir le tube en place. En variante, les éléments d'interface nasale sont maintenus contre le bord externe des narines. Éventuellement, une jupe est incluse sur le côté externe de la narine pour aider à sceller les fuites d'air. Éventuellement, des volets sont inclus pour aider à maintenir le dispositif en place, tels que des volets latéraux, un volet avant, ou bien les deux. Le volet avant peut être capable d'adhérer au niveau de l'extérieur du nez et comprend éventuellement des bandes élastiques pour ouvrir le passage nasal. En variante, un couvercle nasal est collé au nez et des volets latéraux de fixation maintiennent le dispositif sur le couvercle nasal. Ainsi, le dispositif ne nécessite pas de sangles supplémentaires ou de dispositif cranio-cervical pour maintenir le dispositif en position de fonctionnement pendant le sommeil.
