CA 2211759

Apparatus for generating positive pressure breathing air for patients suffering from obstructive sleep apnea including a nasal assembly comprising plural tube segments each fitted with a nostril engagement member to engage the interior walls and lower edge tissue of the nostril thereby providing both an air-tight seal as well as retention of the apparatus to the patient's nose. No other head retention gear or straps are required. A stress-relieving assembly is provided to interconnect one or more tubes from the nasal assembly to the source of pressurized air. A family of nostril engagement members may be provided to achieve a proper nostril fit. The engagement members may be angled to conform with ordinary nostril divergence.

Cette invention concerne un appareil d'assistance respiratoire fournissant de l'air sous pression aux patients qui souffrent d'apnée obstructive du sommeil. Il comporte un masque nasal dont les tubes s'insèrent de façon étanche dans les narines du patient en prenant appui sur les parois intérieures et le bord inférieur des narines qui assurent en même temps leur maintien en place. Aucun autre moyen, sangle ou autre, n'est nécessaire pour maintenir l'appareil en place. Un dispositif d'interconnection des tubes à effet d'absorption des efforts est prévu entre le masque nasal et la source d'air sous pression. L'appareil peut être assorti de toute une série d'adaptateurs nasaux pour un ajustement approprié. Ces adaptateurs peuvent être coudés pour se conformer aux narines normalement divergentes.
