| 20080302365 | Respiratory Mask - A respiratory mask having a shell and a cushion that is adhered to a user's face is sufficiently rigid to provide dimensional stability and a constant volume between the respiratory mask and the user's face, while also being comfortable and conformable to a user's individual facial features. The respiratory mask may cover the nose, the mouth, or both of the user and is useful for respiratory therapies including sleep apnea. The respiratory mask may have a quick release mechanism such as a pull tab that tears a portion of the mask when pulled to allow access to the user's breathing passage or a pull string embedded in the adhesive that breaks the seal between the adhesive and the user's face when pulled. | 12-11-2008 |
