Abstract
An interface for positive pressure therapy includes a mask assembly. The mask assembly can include a mask seal that is adapted to underlie the nose. The mask seal extends up the lateral sides of the nose. The mask seal has a primary seal below the nose and a secondary seal alongside the nose. The mask seal can include a rolling hinge that permits one portion of the mask seal to deform relative to another portion of the mask seal. In one configuration, the portion of the mask seal that underlies the nose is configured to deform relative to a lower portion of the mask seal.
