Abstract

A ventilation interface and system is described which can be adapted to be connected to a source of ventilation. The ventilation interface and system may include variable exhaust ports. The ventilation interface system may optionally include feed tubes, y-connector, tube holder, and headgear.

Claims

1. A nasal ventilation interface comprising:

a cannula connectable to a source of ventilation gas via at least one ventilation connectors;

at least one reservoir flange coupled to the ventilation connectors and in close proximity with at least one nasal insert;

at least one seal portion positioned on a distal end of the at least one nasal insert;

a central reservoir between the at least one reservoir flange and the nasal insert;

at least one exhaust flange coupled to the central reservoir; and

an exhaust port configured having an adjustable aperture.

2. The ventilation interface according to claim 1, wherein an adjustable dial is configured to adjust the adjustable aperture.

3. The ventilation interface according to claim 1, wherein the adjustable dial is configured with at least one flow setting.

4. The ventilation interface according to claim 3, wherein the flowing setting is ultra low velocity.

5. The ventilation interface according to claim 3, wherein the flow setting is low velocity.

6. The ventilation interface according to claim 3, wherein the flow setting medium velocity.

7. The ventilation interface according to claim 3, wherein the flow setting is medium plus velocity.

8. The ventilation interface according to claim 3, wherein the flow setting is high velocity.

9. The ventilation interface according to claim 1 wherein the dial mechanism is substantially round.

10. The ventilation interface according to claim 1 wherein the dial mechanism is detachable from the ventilation interface.

11. The ventilation interface according to claim 1 wherein the dial mechanism integrated with the ventilation interface.

12. The nasal ventilation interface according to claim 1 wherein the dial mechanism is made from at least one of rubber, plastic silicone, polyethylene or polyurethane.

13. An adjustable dial interface configured to be attachable to a nasal cannula comprising:

a substantially round dial with a variable aperture wherein the substantially round dial is configured with an elongated handle positioned substantially perpendicular to the dial; and

wherein variable aperture increases when the dial is turned in a first direction and the variable aperture decreases when the dial is turned in a second direction.

14. The adjustable dial interface configured to be attachable to a nasal cannula according to claim 14 wherein the substantially round dial mechanism is configured to snap into an exhaust port.

15. The adjustable dial interface configured to be attachable to a nasal cannula according to claim 14 wherein the substantially round dial mechanism is configured to be held into an exhaust port by friction.

16. The adjustable dial interface configured to be attachable to a nasal cannula according to claim 14 wherein the adjustable dial interface is made from at least one of rubber, plastic silicone, polyethylene or polyurethane.

17. An adjustable dial interface configured to be attachable to a nasal cannula comprising:

a substantially round dial with at least one flow velocity openings including a flow velocity cut out;

wherein when the substantially round dial is rotated direction at least one of the flow velocity openings holes pass over the flow velocity cut out.

18. The adjustable dial interface configured to be attachable to a nasal cannula according to claim 17 wherein the substantially round dial mechanism is configured to snap into an exhaust port.

19. The adjustable dial interface configured to be attachable to a nasal cannula according to claim 17 wherein the substantially round dial mechanism is configured be held in an exhaust port by friction.

20. The adjustable dial interface configured to be attachable to a nasal cannula according to claim 17 wherein the adjustable dial interface is made from at least one of rubber, plastic silicone, polyethylene or polyurethane.
