  • Publication number: 20230355906
    Abstract: A cushion assembly for a patient interface includes an elastomeric seal-forming portion that includes a dome-shaped superior region and a saddle-shaped inferior region. The elastomeric sealing portion further includes a first support region extending from the saddle-shaped inferior region to the dome-shaped superior region, the first support region having a consistent elastomeric wall thickness that is greater than the elastomeric wall thickness of the dome-shaped superior region and the saddle-shaped inferior region. In addition, the seal-forming portion include a second support region adjacent the first support region that extends from the saddle-shaped inferior region to the dome-shaped superior region, the second support region being bounded by the first support region on a proximal side and having a distal side opposite the proximal side, the elastomeric wall thickness in the second support region increases from the distal side to the proximal side.

  • Publication number: 20230338686
    Abstract: One form of the present technology includes a sealing structure to seal against a user's face around the user's airways. The sealing structure includes a flap or membrane that extends inward towards the user's airways and includes a structure that prevents an inner boundary of the flap or membrane from being blown outwards (e.g., folded backwards upon itself) due to internal pressurization.

  • Publication number: 20230338690
    Abstract: A cushion assembly for a patient interface including an elastomeric seal-forming structure that is shaped to be bisected by a sagittal plane having a line that is tangent to the elastomeric seal-forming structure at a superior tangent point and at an inferior tangent point. A saddle-shaped superior region of the elastomeric seal-forming structure straddles the sagittal plane and includes the superior tangent point. The elastomeric seal-forming structure transitions in a cylinder-shaped superior region from the saddle-shaped region to a dome-shaped superior region offset from the sagittal plane. In addition, an elastomeric wall thickness of the elastomeric seal-forming structure is greater in the cylinder-shaped superior region than in the saddle-shaped superior region and the dome-shaped superior region.

  • Patent number: 11707590
    Abstract: A cushion assembly for a patient interface includes an elastomeric seal-forming portion with a dome-shaped superior region that is intersected by the sagittal plane in the vicinity of a superior tangent point. The seal-forming portion further including a saddle-shaped inferior region that is intersected by the sagittal plane and includes an inferior tangent point. A first support region is located on one side of the sagittal plane between the inferior region and the superior region, the exterior surface of the elastomeric seal forming portion at the first support region being cylinder-shaped and/or saddle-shaped. In addition, a blowout prevention system is configured to counter a force acting on the unsupported edge of the elastomeric seal-forming portion due to a pressure within the chamber, the blowout prevention system being attached to the elastomeric seal-forming portion at the first support region of the elastomeric seal-forming portion.
