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.
Claims33
An interface for use in providing positive pressure respiratory therapy, the interface comprising:
- a mask assembly comprising a mask seal and a mask base, the mask assembly configured to be fully positioned lower than a bridge of a nose of a face of a user and the mask assembly configured to provide an exposed tip of the nose of the user;
- the mask base comprising a central portion and a pair of wings sweeping rearwardly of the central portion, an opening for a connector being formed on the mask base in the central portion;
- the mask seal being connected to the mask base, the mask seal comprising at least one oral opening on a lower portion and at least one nasal opening on an upper portion, the at least one oral opening being positioned opposite of the opening for the connector and the at least one nasal opening being positioned between the opening for the connector and the at least one oral opening in a front to back direction;
- and
- the mask seal comprising a first paddle and a second paddle, an upper support surface being positioned between the first paddle and the second paddle such that an upwardly-open valley is defined by the first paddle, the upper support surface and the second paddle, at least a portion of the at least one nasal opening being positioned on the upper support surface within the valley;
- wherein the mask seal further comprises a rolling hinge positioned between an upper surface of the mask base and the upper support surface, which permits the upper portion of the mask seal to deform downwardly relative to the lower portion of the mask seal such that it rolls over and onto an outer surface of the mask seal.
