Respiratory devices
First Claim
1. A nasal respiratory device adapted to be secured at least partially over a subject'"'"'s nose comprising:
- a nasal mask body configured to be secured at least partially over the subject'"'"'s nose without covering the subject'"'"'s mouth;
an airflow resistor coupled to the nasal mask body and configured to increase the resistance to air exhaled through the device more than the resistance to air inhaled through the device; and
a holdfast comprising one or more straps configured to secure the nasal mask body at least partially over the subject'"'"'s nose.

Abstract
Described here are devices for altering the flow of air in a respiratory cavity such as the mouth and nostrils of the nose. These methods and devices may be useful for affecting a physiologic benefit in patients suffering from a variety of medical diseases, particularly those that may benefit from “pursed-lip” breathing and non-invasive ventilation, such as COPD, heart failure, sleep apnea, and other medical disorders. The devices are typically removable devices that may be placed over or in a respiratory cavity to increase resistance to airflow within the respiratory cavity. Resistance to expiration may be selectively increased relative to inspiration. Removable oral and removable nasal devices are described. Oral and nasal devices that filter inhaled airflow of debris and allergens are also provided. A nasal device that increases patency of the nares is also provided.

12. A nasal respiratory device adapted to be secured in communication with a subject'"'"'s nasal cavity comprising:
-
a nasal mask body configured to fit at least partly over the subject'"'"'s nose without covering the subject'"'"'s mouth, the nasal mask body having an opening configured to communicate with the nasal cavity; an airflow resistor in communication with the opening and configured to increase the resistance to air exhaled through the opening to be more than the resistance to air inhaled through the opening; and a holdfast comprising one or more straps. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of inhibiting exhalation through the nose more than inhalation through the nose, the method comprising:
-
placing a nasal mask at least partially over the subject'"'"'s nose, wherein the nasal mask comprises a nasal mask body and an airflow resistor coupled to the nasal mask body that is configured to increase the resistance to air exhaled through the nasal mask more than the resistance to air inhaled through the nasal mask; and securing the nasal mask at least partially over the subject'"'"'s nose without covering the subject'"'"'s mouth. - View Dependent Claims (24, 25, 26, 27)
