Claims21

Dependent claims

A patient interface configured to deliver breathable gas to a patient, the patient interface comprising:

a sealing portion with a sealing surface, at least a portion of which is configured to seal against an underside of the patient's nose without engaging the patient's nasal bridge, a thickness of the sealing surface being varied so that the sealing surface is thicker on lateral sides of the sealing surface than at a central region of the sealing surface;
a support portion attached to an anterior side of the sealing portion;
a first connector located on a first lateral end of the support portion and configured to attach to a first connecting member of a headgear assembly;
a second connector located on a second lateral end of the support portion opposite the first lateral end, the second connector being configured to attach to a second connecting member of the headgear assembly;
and
an alignment indicator positioned on the support portion adjacent to the first connector in a location configured to align with a corresponding mark on the first connecting member of the headgear assembly,
wherein the first and second connectors have the same structure.

4 more elements

A patient interface configured to deliver breathable gas to a patient, the patient interface comprising:

a sealing portion configured to seal against a patient's face, at least part of the sealing portion being configured to seal against an underside of the patient's nose without engaging the patient's nasal bridge, the sealing portion comprising a nose tip engagement portion configured to engage a nose tip of the patient in use, an upper lip engagement portion configured to engage an upper lip of the patient in use, and a pair of nostril engagement portions configured to engage the patient's nostrils;
a support portion attached to an anterior side of the sealing portion, the support portion being more rigid than the sealing portion;
a first connector on a first lateral side of the patient interface and configured to attach to a first connecting member of a headgear assembly;
a second connector located on a second lateral side of the patient interface opposite the first lateral side, the second connector being configured to attach to a second connecting member of the headgear assembly;
and
an alignment indicator adjacent to the first connector in a location configured to align with a corresponding mark on a corresponding connecting member of the headgear assembly,
wherein the first and second connectors have the same structure,
wherein there is a gap between the support portion and the nose tip engagement portion that allows the nose tip engagement portion to be moved toward the support portion when the nose tip engagement portion is contacted by the patient's nose.
