Abstract

In accordance with at least one exemplary embodiment, a ventilation system for providing gas under a first pressure to the nose of a user and second pressure to the mouth of a user is disclosed. A ventilation system can include a flow generator that can be connected to a gas supply tube. The gas supply tube can be in fluid communication with a ventilation interface. At least a portion of the gas supply tube can have a divider within the channel of the tube forming a nasal passageway and an oral passageway. A nasal breathing chamber and an oral breathing chamber can be defined in the ventilation interface. The nasal breathing chamber can be in fluid communication with the nasal passageway. The oral breathing chamber can be in fluid communication with the oral passageway.

Claims

1. A ventilation system comprising:

a ventilation mask having a plurality of breathing chambers;

a gas supply tube, wherein the gas supply tube is in fluid communication with the ventilation mask.

2. The ventilation system of claim 1, wherein the plurality of breathing chambers include a nasal breathing chamber and an oral breathing chamber;

wherein the ventilation mask includes a nasal breathing interface and an oral breathing interface; and

wherein the nasal breathing interface is in fluid communication with the nasal breathing chamber and the oral breathing interface is in fluid communication with the oral breathing chamber.

3. The ventilation system of claim 1, wherein the gas supply tube has a plurality of channels;

and

wherein at least one of the plurality of channels is in fluid communication with at least one of the plurality of breathing chambers.

4. The ventilation system of claim 3, wherein the gas supply tube has at least one divider that runs substantially the full length of the gas supply tube.

5. The ventilation system of claim 2, wherein the gas supply tube has a plurality of channels;

wherein at least one of the plurality of channels is in fluid communication with at least one of the plurality of breathing chambers; and

wherein the plurality of channels includes an oral channel and a nasal channel, wherein the oral channel is in fluid communication with the oral breathing chamber and the nasal channel is in fluid communication with the nasal breathing chamber.

6. The ventilation system of claim 3, wherein at least one of the plurality of channels includes a valve, which adjusts the fluid flow through the channel.

7. The ventilation system of claim 1, wherein at least one of the plurality of breathing chambers includes a valve, which adjusts the fluid flow from the gas supply tube to at least one of the plurality of chambers.

8. The ventilation system of claim 3, wherein at least one of the plurality of breathing chambers includes a valve, which adjusts the fluid flow from at least one of the plurality of channels to at least one of the plurality of chambers.

9. The ventilation system of claim 2, wherein the oral breathing chamber and the nasal breathing chamber each include a valve, which adjusts the fluid flow into the oral breathing chamber and the nasal breathing chamber.

10. The ventilation system of claim 2, wherein the ventilation mask includes a dividing wall that provides a substantially airtight seal between the nasal breathing chamber and the oral breathing chamber.

11. The ventilation system of claim 2, wherein the ventilation mask is adapted to enclose a mouth and a nose of a user.

12. The ventilation system of claim 2, wherein the nasal interface includes nasal prongs that are adapted to enter at least one of the nostrils of a user.

13. The ventilation system of claim 1, further comprising:

a flow generator, wherein the flow generator is in fluid communication with the gas supply tube.

14. A ventilation mask comprising:

a plurality of breathing chambers, wherein the plurality of breathing chambers include a nasal breathing chamber and an oral breathing chamber;

wherein the ventilation mask includes a nasal breathing interface and an oral breathing interface; and

wherein the nasal breathing interface is in fluid communication with the nasal breathing chamber and the oral breathing interface is in fluid communication with the oral breathing chamber.

15. The ventilation mask of claim 14, further comprising:

a shell, wherein the shell includes an inlet port adapted to receive a gas supply tube.

16. The ventilation mask of claim 15, wherein at least one of the plurality of breathing chambers includes a valve, which adjusts the fluid flow entering the inlet port.

17. The ventilation mask of claim 14, further comprising:

a dividing wall that provides a substantially airtight seal between the nasal breathing chamber and the oral breathing chamber.

18. The ventilation mask of claim 14, wherein the ventilation mask is adapted to enclose a mouth and a nose of a user.

19. The ventilation mask of claim 14, wherein the nasal interface includes nasal prongs that are adapted to enter at least one of the nostrils of a user.

20. The ventilation mask of claim 14, wherein the oral breathing chamber and the nasal breathing chamber each include a valve, which adjusts the fluid flow into the oral breathing chamber and the nasal breathing chamber.
