Abstract

A mask assembly for delivering breathable gas to a patient may include a patient interface structured to engage the patient's face and provide a seal, a headgear arrangement to support the patient interface in a desired position on the patient's face, and an audio unit provided to at least one of the patient interface and the headgear arrangement. The audio unit may be operable to selectively generate at least one sound.

First claim

What is claimed is:

1. A mask assembly for delivering breathable gas to a patient, comprising:
a patient interface structured to engage the patient's face and provide a seal;
a headgear arrangement to support the patient interface in a desired position on the patient's face; and
an audio unit provided to at least one of the patient interface and the headgear arrangement, the audio unit operable to selectively generate at least one sound, wherein the audio unit is controlled based on at least one monitored parameter of the patient associated with a sleep state of the patient.

2. The mask assembly according to claim 1 , wherein the audio unit is incorporated into the headgear arrangement adjacent the ears of the patient.

3. The mask assembly according to claim 1 , further comprising a control unit provided to at least one of the patient interface and the headgear arrangement, the control unit operable to control operation of the audio unit.

4. The mask assembly according to claim 3 , wherein the control unit is further operable to adjust one or more parameters of a flow generator configured to deliver the breathable gas to the mask assembly.

5. The mask assembly according to claim 1 , further comprising an aromatic unit provided to at least one of the patient interface and the headgear arrangement, the aromatic unit operable to selectively release at least one aroma.

6. The mask assembly according to claim 5 , wherein the aromatic unit is controlled based on at least one monitored parameter of the patient.

7. The mask assembly according to claim 5 , further comprising a control unit provided to at least one of the patient interface and the headgear arrangement, the control unit operable to control operation of the aromatic unit.

8. The mask assembly according to claim 7 , wherein the control unit is further operable to adjust one or more parameters of a flow generator configured to deliver the breathable gas to the mask assembly.

9. The mask assembly according to claim 1 , further comprising a projection unit provided to at least one of the patient interface and the headgear arrangement, the projection unit operable to project an image onto a surface adjacent the mask assembly.

10. The mask assembly according to claim 9 , wherein the projection unit is controlled based on at least one monitored parameter of the patient.

11. The mask assembly according to claim 9 , further comprising a control unit provided to at least one of the patient interface and the headgear arrangement, the control unit operable to control operation of the projection unit.

12. The mask assembly according to claim 11 , wherein the control unit is further operable to adjust one or more parameters of a flow generator configured to deliver the breathable gas to the mask assembly.

13. The mask assembly according to claim 1 , wherein the audio unit includes an earphone.

14. The mask assembly according to claim 1 , wherein the at least one monitored parameter of the patient includes volume of the patient's breathing.

15. The mask assembly according to claim 1 , further comprising a controller configured to control the audio unit to vary a volume of the audio unit based on the patient's sleep state for at least a portion of a sleep duration.

16. A mask assembly for delivering breathable gas to a patient, comprising:
a patient interface structured to engage the patient's face and provide a seal;
a headgear arrangement to support the patient interface in a desired position on the patient's face; and
a projection unit provided to at least one of the patient interface and the headgear arrangement, the projection unit operable to project an image onto a surface; and a controller configured to control the projection unit based on at least one monitored parameter of the patient associated with a sleep state of the patient.

17. The mask assembly according to claim 16 , further comprising an audio unit provided to at least one of the patient interface and the headgear arrangement.

18. The mask assembly according to claim 17 , wherein the audio unit is controlled based on the at least one monitored parameter of the patient.

19. The mask assembly according to claim 17 , wherein the controller is configured to control the audio unit to vary a volume of the audio unit based on a patient's sleep state for at least a portion of patient's sleep.

20. A mask assembly for delivering breathable gas to a patient, comprising:
an audio unit operable to selectively generate sound;
a patient interface structured to engage the patient's face and provide a seal, the patient interface including the audio unit;
a headgear arrangement to support the patient interface in a desired position on the patient's face, wherein the audio unit is disposed in the patient interface; and a controller configured to control the audio unit based on at least one monitored parameter of the patient associated with a sleep state of the patient.

21. The mask assembly according to claim 20 , wherein the controller is configured to control the audio unit to vary a volume of the generated sound based on the patient's sleep state for at least a portion of patient's sleep.

22. The mask assembly according to claim 20 , wherein the controller configured to control the audio unit to vary a volume of the generated sound based on the at least one monitored parameter of the patient.
