Title
(EN) METHOD AND APPARATUS FOR ADJUSTING RESPIRATORY MASK SEALING FORCE
(FR) PROCEDE ET APPAREIL POUR AJUSTER LA FORCE D'ETANCHEITE D'UN MASQUE RESPIRATOIRE
Abstract
(EN) A mask assembly includes a mask with an inflatable bladder (101). The internal pressure of the inflatable bladder (101) can be set to be higher than the delivered therapeutic pressure. The pressure offset may be constant, or it may vary over the range of therapeutic pressures. Thus, the force necessary to maintain a contact seal between the mask and the patient can be reduced, thereby providing a system that is more comfortable to the patient, which increases patient compliance.
(FR) Il est décrit un ensemble de masque qui comprend une vessie gonflable (101). La pression interne de la vessie gonflable (101) peut être définie de manière à être supérieure à la pression thérapeutique délivrée. La différence de pression peut être constante, ou elle peut varier dans la plage de pressions thérapeutiques. Par conséquent, la force nécessaire pour maintenir un joint d'étanchéité par contact entre le masque et le patient peut être réduite, de manière à produire un système qui est plus confortable pour le patient, qui augmente l'observance du patient.
