Adhesive devices and methods for improving breathing and/or sleep using such devices

A method for improving breathing of a PAP user, comprising:

• placing a nasal mask for a PAP device over a user's nose;
• applying an adhesive layer of a membrane over the user's mouth to prevent breathing through the user's mouth, the membrane comprising a one-way valve therein covering one or more openings;
• activating the PAP device, wherein activating the PAP device creates a positive pressure within the user's mouth that substantially seals the one-way valve to prevent flow through the one or more openings;
• and
• inhaling to generate a predetermined negative pressure within the user's mouth, thereby causing the one-way valve to open and allow air to pass through the one or more openings into the user's mouth,
• wherein the membrane is stretchable to allow the user to open the mouth until the one-way valve no longer covers the one or more openings to allow the user to inhale and exhale, and wherein the membrane is biased to resiliently close, thereby covering the one or more openings with the one-way valve when the user relaxes the mouth.

A method for improving nasal breathing, comprising:

• applying an adhesive layer of a membrane over a user's mouth with the user's lips pressed together, the membrane comprising a one-way valve therein covering one or more openings, and wherein positive pressure within the user's mouth substantially seals the one-way valve to prevent flow through the one or more openings;
• sleeping with the membrane over the user's mouth to inhibit breathing through the user's mouth;
• and
• inhaling to generate a predetermined negative pressure within the user's mouth, thereby causing the one-way valve to open and allow air to pass through the one or more openings into the user's mouth,
• wherein the membrane is stretchable to allow the user to open the mouth until the one-way valve no longer covers the one or more openings to allow the user to inhale and exhale, and wherein the membrane is biased to resiliently close, thereby covering the one or more openings with the one-way valve when the user relaxes the mouth.
