Abstract

The present invention discloses 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 of a patient's nares and to an entrance of the patient's mouth, wherein the patient interface 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 a patient's respiratory cycle, while the patient is sleeping, to ameliorate sleep disordered breathing; said patient interface comprising: a plenum chamber at least partially forming a cavity pressurisable to a therapeutic pressure of at least 6 cmH2O above ambient air pressure, said plenum chamber including at least one plenum chamber inlet port sized and structured to receive a flow of air at the therapeutic pressure for breathing by a patient; and a seal-forming structure comprising a textile membrane constructed and arranged to form a seal with a region of the patient's face surrounding the entrance to the patient's nares and the entrance to the patient's mouth, the seal-forming structure comprising: a nasal portion configured to at least partially surround the entrance to the patient's nares, and an oral portion configured to at least partially surround the entrance to the patient's mouth, wherein said textile membrane has at least one hole such that the flow of air at said therapeutic pressure is delivered to at least an entrance to the patient's nares and/or the patient's mouth, the seal-forming structure constructed and arranged to maintain said therapeutic pressure in the cavity throughout the patient's respiratory cycle in use, wherein the textile membrane includes a three-dimensional shape having multiple curvatures, wherein the seal-forming structure further includes a flexible support structure for holding the textile membrane in the three-dimensional shape.
