Abstract
A patient interface to provide breathable gas to a patient, comprising: a plenum chamber assembly, comprising: a nasal plenum chamber at least partly defining an upper gas chamber; an oral plenum chamber at least partly defining a lower gas chamber; and a decoupling structure at least partly connecting the nasal plenum chamber and the oral plenum chamber and at least party defining a flow path; a top plate including at least one connection feature configured to releasably retain a first portion of a positioning and stabilising structure; and a faceplate configured to releasably retain a second portion of a positioning and stabilising structure.
Claims30
A patient interface to provide breathable gas to a patient, comprising:
- a cushion assembly, comprising:
- a nasal cushion having a concave shape between a first lateral side and a second lateral side to receive and seal against an inferior periphery of the patient's nose, the nasal cushion including a nasal opening configured to direct breathable gas to the patient's nares in use;
- an oral cushion configured to contact and seal against the patient's face surrounding the patient's mouth, the oral cushion including an oral opening configured to direct breathable gas to the patient's mouth in use;
- and
- a plenum chamber including a nasal portion and an oral portion, and the plenum chamber, the nasal cushion, and the oral cushion at least partly forming a gas chamber;
- an anti-asphyxiation valve;
- a positioning and stabilizing structure including a pair of upper side straps, a pair of lower side straps, and a rear portion, the pair of upper side straps and the pair of lower side straps extending from the rear portion;
- and
- a unitary plate member removably connected to the cushion assembly, the unitary plate member including a connection port configured to be connected to an air delivery tube, the connection port being configured to receive breathable gas from the air delivery tube and direct breathable gas into the cushion assembly for breathing by the patient during use, the unitary plate member including an upper portion and a lower portion, and the upper portion of the unitary plate member contacting the nasal portion of the plenum chamber to support the nasal cushion against the patient's face in use,
- wherein the nasal portion of the plenum chamber includes an anterior side and lateral sides that extend posteriorly from the anterior side, the anterior side and the lateral sides including a depressed region, and
- wherein the upper portion of the unitary plate member is shaped and dimensioned to complement a lower surface of the depressed region along the anterior side and lateral sides of the nasal portion of the plenum chamber when the unitary plate member is removably connected to the cushion assembly.

- a cushion assembly, comprising:
- a nasal plenum chamber portion including a nasal cushion having a concave shape between a first lateral side and a second lateral side to receive and seal against an inferior periphery of the patient's nose, the nasal cushion including a nasal opening configured to direct breathable gas to the patient's nares in use;
- and
- an oral plenum chamber portion including an oral cushion configured to contact and seal against the patient's face surrounding the patient's mouth, the oral cushion including an oral opening configured to direct breathable gas to the patient's mouth in use,
- an anti-asphyxiation valve;
- a positioning and stabilizing structure including upper straps, lower straps, and a rear portion, the upper straps and the lower straps extending from the rear portion;
- and
- a faceplate having a connection port configured to be connected to an air delivery tube, the connection port being configured to receive breathable gas from the air delivery tube and direct breathable gas into the cushion assembly for breathing by the patient during use;
- a top plate;
- and
- a connection portion that joins the top plate and the faceplate to form a unitary structure that is removably connected to the cushion assembly, wherein the top plate contacts the nasal plenum chamber portion to support the nasal cushion against the patient's face in use,
- wherein the nasal portion of the plenum chamber includes an anterior side and lateral sides that extend in a posterior direction relative to the patient from the anterior side, the nasal portion of the plenum chamber including a depressed region that extends across the anterior side and the lateral sides, and
- wherein the top plate is shaped and dimensioned to complement a lower surface of the depressed region across the anterior side and lateral sides of the nasal plenum chamber portion when the unitary structure is removably connected to the cushion assembly.
