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 nasal respiratory device to be worn when sleeping, the device comprising:

a flexible and substantially flat body configured to secure at least partially over both of a subject'"'"'s nostrils, wherein the body includes a valve region and a holdfast region;

wherein the valve region is configured to inhibit exhalation through the nostrils more than inhalation through the nostrils; and

further

wherein the holdfast region is configured to adhesively secure the device around a subject'"'"'s nostrils.

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

3. The device of claim 1, wherein the valve region comprises a plurality of flap valves.

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

5. The device of claim 1, further wherein the valve region comprises a flap valve layer adjacent to a flap valve limiter layer.

6. The device of claim 1, wherein the holdfast region surrounds the airflow resistor.

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

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

9. The device of claim 1, wherein the adhesive holdfast region comprises a substrate and a biocompatible adhesive.

10. The device of claim 1, wherein the body is substantially elongate.

11. The device of claim 1, wherein an outer perimeter of the body includes an inwardly curving region.

12. The device of claim 1, further comprising a removable protective cover layer covering at least part of the holdfast region.
