Abstract

interface for sealed delivery of a flow of air at a continuously positive pressure to an entrance to the airways of a patient, comprising a positioning and stabilising structure to maintain a seal-forming structure in contact with the patient's face; the structure including a pair of rigidizer arms connected to respective sides of a plenum chamber, each rigidizer arm being surrounded by a respective rigidizer arm cover (3310) to cushion the patient’s face against the rigidizer arm; a pair of side straps (3301) configured to extend along respective sides of the patient’s face between the patient’s eye and ear when the patient interface is worn. Each side strap is connected to an end portion of a corresponding one of the rigidizer arm covers such that, in use, the corresponding rigidizer arm does not extend along a portion of the patient’s face between the patient’s eye and ear; a posterior portion connected to the side straps and including a crown strap (3307) and a rear strap (3305), wherein each of the rigidizer arm covers, the side straps, the crown strap and the rear strap comprises a textile material, wherein the side straps comprise a different textile material than the crown strap and/or the rear strap, and wherein the side straps have increased stretchability as compared to the crown strap and/or the rear strap. The disclosed positioning and stabilising structure acts to cushion the patient's face against rigidiser arms that aid with sealed delivery of air, thus providing enhanced comfort.

Claims (18)

1. A patient ace for sealed ry of a flow of air at positive pressure with respect to ambient air pressure to an entrance to the airways of a patient including at least the nares of the patient, wherein the patient ace is configured to maintain a therapy pressure in a range of about 4 cmH2O to about 30 cmH2O above ambient air pressure in use, hout the patient’s respiratory cycle, while the patient is sleeping, to ameliorate sleep disordered breathing, said patient ace comprising: a plenum chamber at least partially forming a ing chamber pressurisable to a therapeutic pressure above ambient air pressure, said plenum r including a plenum chamber inlet sized and structured to receive a flow of air at the therapeutic pressure for breathing by a t; a seal-forming structure constructed and arranged to form a seal with a region of the patient’s face surrounding an entrance to the patient’s airways, said sealforming structure having an opening formed therein such that the flow of air at said therapeutic pressure is delivered to at least an entrance to the patient’s nares; and a positioning and stabilizing structure to maintain the seal-forming structure in sealing contact with the patient’s face, the positioning and izing structure including: a pair of rigidizer arms connected to respective sides of the plenum chamber, each zer arm being surrounded by a respective rigidizer arm cover to cushion the patient’s face against the rigidizer arm; a pair of side straps configured to extend along respective sides of the patient’s face between the patient’s eye and ear when the patient interface is worn, each side strap being connected to an end portion of a corresponding one of the rigidizer arm covers such that, in use, the corresponding rigidizer arm does not extend along a portion of the patient’s face disposed between the patient’s eye and ear; and a posterior portion connected to the side straps and including a crown strap and a rear strap, the crown strap being configured to extend over or nt to a crown of the patient’s head in use, the rear strap being ured to extend around a rear portion of the patients’ head in use, wherein each of the rigidizer arm covers, the side straps, the crown strap and the rear strap ses a textile material, wherein the side straps comprise a different e material than the crown strap and/or the rear strap, and wherein the side straps have increased stretchability as compared to the crown strap and/or the rear strap.

6. The patient interface of any one of claims 1 to 5, wherein the seal-forming structure comprises a textile ne configured to seal t the patient’s face in
7. The patient ace of claim 6, wherein the textile membrane is stretchable.
8. The patient interface of any one of claims 6 and 7, wherein the sealforming structure includes a cushioning layer arranged such that the textile membrane covers the cushioning layer in use.
9. The patient interface of claim 8, wherein the ning layer comprises spacer fabric.
10. The patient ace of any one of claims 6 to 9, wherein the seal-forming structure includes a foam interior portion that, in use, provides support to the textile membrane.
11. The patient interface of any one of claims 1 to 10, further comprising a vent to, in use, expel exhaust gases to here.
12. The patient interface of claim 11, wherein the vent is disposed on the plenum chamber.
13. The patient interface of any one of claims 11 and 12, wherein the vent comprises a spacer fabric mesh.
14. The patient interface of any one of claims 1 to 13, further comprising a connection port formed in the plenum r for connection with a supply air circuit.
15. The patient interface of claim 14, n the connection port comprises an overmolded ring configured to engage a connector on the supply air circuit to connect the supply air circuit to the plenum chamber.
16. The t interface of any one of claims 1 to 15, wherein each of the rigidizer arm covers, the side straps, the crown strap and the rear strap comprises a knitted textile material.
17. The patient interface of any one of claims 6 to 10, wherein when the textile membrane is in sealing engagement with the patient’s face during use, the textile membrane is ured to inflate upon pressurization of the breathing chamber.
18. The patient interface of any one of claims 1 to 17, wherein the sealforming structure is ucted and arranged to form a seal with an underside of the patient’s nose.
