Abstract

A patient interface that reliably and comfortably seals a user'"'"'s face by providing an oral-nasal mask that includes an integrated nasal interface. The patient interface includes a seal member having an oral cushion portion configured to surround the user'"'"'s mouth and a nasal interface portion that provides an interface with the user'"'"'s nose. The seal member, including the oral cushion portion and the nasal interface portion, is a unitary member. Finally, the nasal interface portion remains below the bridge of the nose.

Claims

1. A patient interface comprising:

a seal member adapted to contact a face of a user to provide a sealed interface with such a user, wherein the seal member comprises;

(1) an oral cushion portion adapted to provide a sealed interface with such a user, wherein a sealing of the oral cushion portion at least partially surrounds a mouth of such a user, and

(2) a nasal interface portion integral with the oral cushion portion, wherein the nasal interface portion is adapted to contact at least a portion of a nose of such as user below a bridge of the nose to provide a sealed interface with a surface of such a user proximate to the nares of such a user.

2. The patient interface of claim 1, wherein the nasal interface portion comprises a protrusion that extends from the oral cushion portion, and wherein the protrusion is sized and configured that the protrusion is bounded at its upper extremity by a lower end of a nose of such a user.

3. The patient interface of claim 1, wherein the nasal interface portion comprises is a nasal cup or a pair of nasal pillows.

4. The patient interface of claim 1, wherein the nasal interface portion comprises is a pair of nasal pillows, and wherein the nasal pillows both have a generally concave exterior shape.

5. The patient interface of claim 1, wherein the oral cushion portion includes a first end portion, a second end portion adapted to contact a surface of a user, and a wall extending between the first end portion and the second end portion.

6. The patient interface of claim 5, wherein a pleat is defined in the wall.

7. The patient interface of claim 5, wherein a chamber is defined by the oral cushion portion, and wherein the second end portion includes a distal edge portion that extends generally toward the chamber.

8. The patient interface of claim 1, wherein the oral cushion portion comprises a bladder having an interior.

9. The patient interface of claim 8, wherein the interior of the bladder is gas-filled or gel-filled.

10. The patient interface of claim 8, wherein the interior of the bladder is gas-filled and further comprising a valve for controlling inflation of the gas-filled interior.

11. The patient interface of claim 1, wherein a first opening is defined in the oral cushion portion to provide a seal around such a user'"'"'s mouth and a second opening is defined in the nasal interface portion to provide a seal around at least one of such a user'"'"'s nares.

12. The patient interface of claim 1, wherein the oral cushion portion is generally oval shaped.

13. The patient interface of claim 1, further comprising a reinforcing member associated with the oral cushion portion, the nasal interface portion, or both to provide structural support for an associated portion of the seal member.

14. The patient interface of claim 1, further comprising a faceplate, wherein the seal member is coupled to the faceplate.

15. The patient interface of claim 14, further comprising means for attaching the seal member to the faceplate.

16. The patient interface of claim 1, further comprising a headgear coupled to the faceplate.

17. The patient interface of claim 15, further comprising means for attaching the headgear to the faceplate.

18. The patient interface of claim 1, wherein the faceplate includes a headgear attachment element.

19. The patient interface of claim 1, further comprising a patient circuit connector rotatably attached to the shell.
