Abstract
The present invention relates to a device for avoiding leakage from the mouth when nasally supplying a respiratory gas on a pressure level lying above ambient pressure. The device comprises a base body made from an elastomeric material and comprises an inner edge portion and an outer ring edge portion, wherein the two ring edge portions are coupled with each other via a web portion, and wherein furthermore the base body, in combination with the two ring edge portions and the web portion, is configured in such a manner that in the application position of the base body the latter defines a lip receiving area for receiving the lips of the user.

A mouth seal assembly for use with a nasal mask system supplying a respiratory gas on a pressure level lying above ambient pressure, comprising:
- a mouth seal formed from an elastomeric material, the mouth seal having a lip receiving area adapted to receive lips of a patient, the mouth seal being a solid member dimensioned to cover a mouth of the patient in use,
- wherein the mouth seal is adapted to suppress exhalation of air from the patient's mouth.
A mouth seal assembly for use with a nasal mask system supplying a respiratory gas on a pressure level lying above ambient pressure, comprising:
- a mouth seal formed from an elastomeric material, the mouth seal being a solid member dimensioned to cover a mouth of the patient;
- and
- a lift-off device being structured to deform the mouth seal upon application of tensile forces to the lift-off device to facilitate removal of the mouth seal from the mouth of the user.
A mouth seal assembly for use with a nasal mask system supplying a respiratory gas on a pressure level lying above ambient pressure, comprising:
- a mouth seal formed from an elastomeric material, the mouth seal having a an essentially elliptically and concavely bulged lip rest area, the mouth seal being a solid member dimensioned to cover a mouth of the patient in use,
- wherein the mouth seal does not include an aperture so as to completely suppress leak through the mouth seal.
