Abstract

cushion assembly for a patient interface that includes an elastomeric seal-forming portion with a dome-shaped superior region (3180A), a saddle-shaped superior region, and a saddle-shaped inferior region (3180G). First (3180E) and second (3180D) support regions extend between the dome shaped region (3180A) and saddle-shaped region (3180G). The first support region has a consistent wall thickness, preferably 2 mm, that is greater than the thickness of the dome-shaped superior and the saddle-shaped inferior. The wall thickness in the second support region (3180D) decreases away from the first support region, preferably from 2 to 1.3mm. The mask may further include a third support region (3180F), a compliant region (3180C) and a flap that borders the saddle-shaped superior region (3180B) near a tie (3110) that may be used to connect seal regions closer to the nose to the support regions.

Claims (13)

1. A cushion assembly for a patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to a patient's airways including at least entrance of the patient's nares, wherein the patient interface is configured to maintain a therapy pressure in a range of about 4 cmH20 to about 30 cmH20 above ambient air pressure in use, throughout the patient's respiratory cycle, while the patient is sleeping, to ameliorate sleep disordered breathing, the cushion assembly comprising: an elastomeric seal-forming portion shaped to be bisected by a sagittal plane that includes a line tangent to the elastomeric seal-forming portion at a superior tangent point and an inferior tangent point; and a tie with at least one end attached to the elastomeric seal-forming portion, wherein the elastomeric seal-forming portion comprises: a dome-shaped superior region that straddles the sagittal plane in the vicinity of the superior tangent point, a saddle-shaped superior region that straddles the sagittal plane in the vicinity of the superior tangent point, a saddle-shaped inferior region that straddles the sagittal plane and includes the inferior tangent point, 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, a second support region adjacent the first support region that is between the saddle-shaped inferior region and 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, and a flap portion that borders the saddle-shaped superior region and extends from a location where the tie is attached to the elastomeric seal-forming portion.
2. The cushion assembly of claim 1, wherein the elastomeric wall thickness of the second support region at the proximal side is the same as the elastomeric wall thickness of the first support region.
3. The cushion assembly of any one of claims 1 to 2, wherein the elastomeric seal- forming portion further comprises a third support region adjacent the second support region, the second support region being bounded by the third support region at the distal side.
4. The cushion assembly of claim 3, wherein the elastomeric wall thickness of the third support region is the same as the elastomeric wall thickness at the distal side of the second support region.
5. The cushion assembly of any one of claims 1 to 4, wherein the elastomeric wall thickness in the saddle-shaped superior region is less than the elastomeric wall thickness in the dome-shaped superior region.
6. The cushion assembly of any one of claims 1 to 5, wherein the elastomeric seal- forming portion further comprises a compliant region bounded by the second support region and the saddle-shaped superior region.
7. The cushion assembly of claim 6, wherein the elastomeric wall thickness in the compliant region is greater than the elastomeric wall thickness of the saddle-shaped superior region and the elastomeric wall thickness of the dome-shaped superior region.
8. The cushion assembly of any one of claims 6 to 7, wherein the elastomeric wall thickness in the compliant region is less than the elastomeric wall thickness of the first support region.
9. The cushion assembly of any one of claims 6 to 8, wherein the elastomeric wall thickness in the flap portion is less than the elastomeric wall thickness in the compliant region.
10. The cushion assembly of any one of claims 1 to 9, wherein the flap portion is configured to move independently of the tie.
11. The cushion assembly of any one of claims 1 to 10, wherein the elastomeric seal- forming portion is dome-shaped at the superior tangent point.
12. A patient interface comprising: the cushion assembly of any one of claims 1 to 11; a rigid shell removably connected to the cushion assembly; and headgear removably attached to the rigid shell.
13. A CPAP system comprising: the patient interface of claim 12; a flow generator configured to pressurize a flow of gas; and an air delivery tube configured to deliver the pressurized gas to the patient interface.
