Abstract
A mask interface for a respiratory mask, in which the mask interface comprises a resilient mask housing at least partially formed from a textile and being configured to deform under pressure from an external force, such as when being pressed against a pillow, and to substantially return to its original shape either automatically or by manipulation by a user.
Claims25
A mask interface configured to deliver breathing gas to a user, the mask interface comprising:
- a seal comprising a gas inlet configured to seal against a face of the user;
- and
- a 3-dimensional mask housing directly or indirectly attached to the seal, wherein breathing gas within the 3-dimensional mask housing passes through the gas inlet of the seal to reach the user, wherein the 3-dimensional mask housing comprises:
- at least one gas inlet opening that permits breathing gas to enter the 3-dimensional mask housing,
- at least one fabric portion, and
- a flexible, resilient support structure configured to at least partially retain a shape of the 3-dimensional mask housing, the flexible, resilient support structure comprising a plurality of support members each comprising a first end and a second end, wherein the second end of each of the plurality of support members is a free end;
- wherein an airtight coating or layer is provided on an internal surface of the at least one fabric portion of the 3-dimensional mask housing in use such that the at least one fabric portion defines at least a portion of an airtight positive pressure chamber of the 3-dimensional mask housing.
