Abstract
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 the patient’s airways, comprising a seal-forming structure comprising a membrane (3100) constructed from a first textile material and configured to contact the patient’s face and seal around at least the patient’s nares, the seal-forming structure having an opening (3101) configured to direct the flow of air to the entrance to the patient’s airways; a clip (3103) secured to the seal-forming structure and configured to releasably attached to the plenum chamber (now shown); and an intermediate clip connector (3104) joined at a first side to the seal-forming structure and joined at a second side opposite the first side to the clip.
Claims (23)
1. A patient interface for sealed delivery of a flow of air at a continuously positive pressure with t to ambient air pressure to an entrance to the patient’s airways including at least a patient’s nares, 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, throughout the patient’s respiratory cycle, while the t is ng, to ameliorate sleep disordered breathing, the patient interface comprising: a plenum chamber configured to be pressurised at a pressure above ambient pressure by the flow of air, the plenum chamber having a connection port configured to be connected to an air delivery tube to receive the flow of air; a seal-forming structure comprising a membrane constructed from a first textile material and configured to contact the patient’s face and seal around the entrance to the patient’s airways including at least the patient’s nares, the sealforming structure having an g configured to direct the flow of air to the entrance to the patient’s s including at least the t’s nares; and a clip releasably ed to the plenum chamber; an intermediate clip connector joined at a first side to the seal-forming structure and joined at a second side opposite the first side to the clip; a vent comprising a plurality of vent holes configured to wash out exhaled gas from the patient during use; and a positioning and stabilising structure configured to maintain the seal-forming structure in g contact with the patient’s face, the positioning and stabilising structure comprising at least one strap constructed from a second textile material. JAWS ref: 506108NZDIV3 ResMed Ref: P1135NZ4

16. The patient ace of any one of claims 14 to 15, wherein the orming structure is configured to inflate under internal pressure when the membrane is sealed against the t’s face.
17. The patient interface of any one of claims 1 to 16, wherein the second textile material is air-permeable.
18. The patient interface of any one of claims 1 to 17, n the vent is positioned on the plenum chamber.
19. The patient interface of any one of claims 1 to 18, wherein the seal-forming structure is a nasal cradle configured to seal around an inferior periphery of the patient’s nose and at or near the tip of the patient’s nose.
20. The t interface of any one of claims 1 to 19, wherein the seal-forming structure comprises nasal pillows, each of the nasal s being configured to seal with a respective naris of the nose of a patient.
21. The patient interface of any one of claims 1 to 20, wherein the seal-forming structure is configured to leave the patient’s mouth uncovered.
22. The patient interface of any one of claims 1 to 21, wherein the seal-forming structure is configured not to contact the bridge of the patient’s nose. JAWS ref: 506108NZDIV3 ResMed Ref: P1135NZ4
23. The patient ace of any one of claims 1 to 22, wherein the seal-forming structure further comprises a foam portion configured to support the membrane against the patient’s face in use.
