Abstract

Whole-nose nasal respiratory devices and methods of making and using whole-nose nasal respiratory devices are described and illustrated herein. These devices are typically configured to be adhesively secured to a subject so that they engage both of the subject'"'"'s nostrils and allow airflow from both nostrils to communicate with an airflow resistor. The airflow resistor is configured so that it inhibits exhalation through the nostrils more than it inhibits inhalation through the nostrils.

Claims

1. A whole-nose nasal respiratory device, the device comprising:

an airflow resistor configured to inhibit exhalation through both nostrils more than inhalation through both nostrils; and

an adhesive holdfast configured to secure the device in communication with both of a subject'"'"'s nostrils.

2. The device of claim 1, wherein the airflow resistor comprises a flap valve.

3. The device of claim 1, wherein the airflow resistor comprises a plurality of flap valves.

4. The device of claim 1, wherein the adhesive holdfast is configured to secure the device at least partly over both of the subject'"'"'s nostrils so that the airflow resistor is positioned outside of the subject'"'"'s nostrils.

5. The device of claim 1, further comprising an opening through the device that is open to allow airflow during both exhalation and inhalation.

6. The device of claim 1, further wherein the airflow resistor comprises a flap valve layer and a flap valve limiter layer.

7. The device of claim 1, wherein the holdfast is configured as an elongated strip surrounding the airflow resistor.

8. The device of claim 1, wherein the resistance to expiration is between about 1 and about 250 cm H₂O/L/sec.

9. The device of claim 1, wherein the resistance to inhalation is between about 0.01 and about 5 cm H₂O/L/sec.

10. The device of claim 1, further comprising a frame in communication with an outer perimeter of the adhesive holdfast, wherein the frame is configured to support to the adhesive holdfast.

11. A whole-nose nasal respiratory device, the device comprising:

an airflow resistor configured to inhibit exhalation through both nostrils more than inhalation through both nostrils,

a flexible, adhesive holdfast surrounding the airflow resistor and configured to secure the airflow resistor in communication with both of the subject'"'"'s nostrils;

a frame in communication with an outer edge of the adhesive holdfast, wherein the frame is configured to support the adhesive holdfast; and

an opening through the device that is open to allow airflow through the device during both exhalation and inhalation.

12. The device of claim 11, wherein the adhesive holdfast comprises a substrate layer and a biocompatible adhesive.

13. The device of claim 11, wherein the airflow resistor comprises a flap valve layer adjacent to a flap valve limiter layer.

14. The device of claim 11, wherein the adhesive holdfast is substantially flat and elongate.

15. The device of claim 11, wherein outer perimeter of the adhesive holdfast includes an inwardly curving region.

16. The device of claim 11, further comprising a removable protective cover layer covering at least part of the adhesive holdfast.

17. The device of claim 11, wherein the resistance to expiration through the device is between about 1 and about 250 cm H₂O/L/sec and the resistance to inhalation through the device is between about 0.01 and about 5 cm H₂O/L/sec.

18. A whole-nose nasal respiratory device, the device comprising:

an elongate holdfast substrate layer comprising a biocompatible adhesive;

a flap valve layer comprising at least one flap valve, wherein the flap valve layer is at least partially surrounded by the elongate holdfast substrate layer;

a flap valve limiter layer adjacent to the flap valve layer and configured to limit the opening of the flap valve(s) so that the device inhibits exhalation more than inhalation through both nostrils;

wherein the whole-nose nasal respiratory device is configured to be substantially flat and flexible, and is further configured to be worn in communication with both of the subject'"'"'s nostrils.

19. The device of claim 18, further comprising at least one opening through the device that is configured to be open during both exhalation and inhalation.

20. The device of claim 18, further comprising a removable protective cover layer covering at least part of the biocompatible adhesive.

21. The device of claim 18, wherein the device is configured so that the resistance to expiration through the device is between about 1 and about 250 cm H₂O/L/sec.

22. The device of claim 18, wherein the device is further configured so that the resistance to inhalation through the device is between about 0.01 and about 5 cm H₂O/L/sec.

23. The device of claim 18, further comprising a frame in communication with an outer edge of the holdfast, wherein the frame is configured to support the holdfast.

24. A method of applying a whole-nose nasal respiratory device, the method comprising:

removing a protective covering layer from at least part of a whole-nose nasal respiratory device, wherein the whole-nose nasal respiratory device comprises an airflow resistor configured to inhibit exhalation through both nostrils more than inhalation through both nostrils and an adhesive holdfast configured to secure the device in communication with both of a subject'"'"'s nostrils; and

adhesively securing the holdfast of the nasal respiratory device at least partly over both of a subject'"'"'s nostrils.

25. The method of claim 24, wherein the step of adhesively securing the nasal respiratory device comprises sealing the adhesive holdfast of the nasal respiratory device to the subject'"'"'s nose.

26. The method of claim 24, wherein the step of removing the protective layer comprises unpeeling the protective layer from the whole-nose respiratory device.
