Abstract
A mask to administer breathable gas to a user may include a body structure having a connection opening to connect to a line device to deliver the breathable gas; a sealing lip device to seal against the user's face, the sealing lip device joined to the body structure, and the sealing lip device having an upper bridge portion structured to cross the bridge of the user's nose in use, a pair of side portions structured to be positioned along corresponding side surfaces of the user's nose in use, and a lower bridge portion structured to cross the user's upper lip or chin region in use; and a pair of beadlike gel cushions, each positioned in a corresponding one of the side portions.
Claims24
A mask to administer breathable gas to a user, the mask comprising:
- a body structure having a connection opening to connect to a line device to deliver the breathable gas;
- a sealing lip device configured to seal against the user's face, the sealing lip device joined to the body structure, and the sealing lip device having an upper bridge portion configured to cross the bridge of the user's nose in use, a pair of side portions configured to be positioned along corresponding side surfaces of the user's nose in use, and a lower bridge portion configured to cross the user's upper lip or chin region in use;
- and
- a pair of elongated gel cushions, each of the pair of elongated gel cushions positioned in a corresponding one of the pair of side portions.
A breathing mask device for administering a breathable gas, the breathing mask device comprising:
- a body structure having a connection opening to connect to a line device to deliver the breathable gas;
- a sealing lip device joined to the body structure;
- a breathing mask interior defined at least in part by the body structure and the sealing lip device;
- a gel structure joined to the body structure, the gel structure configured to at least intermittently and partially transmit retention forces acting on the body structure to the user's face area, the gel structure further comprising an elastically deformable receiving wall and a gel receiving chamber formed at least in part by the elastically deformable receiving wall and the body structure;
- and
- a gel material within the gel receiving chamber,
- wherein the gel receiving chamber forms a bracing bead portion that extends between the body structure of the breathing mask device and the sealing lip device of the breathing mask device, and wherein the body structure is constructed of a first material and the elastically deformable receiving wall is constructed of a second material, the first material and the second material being different materials.
