Abstract: A patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways comprising: a cushion member that includes a retaining structure and a seal-forming structure permanently connected to the retaining structure; a frame member attachable to the retaining structure; and a positioning and stabilising structure attachable to the frame member.

Abstract: A vent adaptor for a for a respiratory pressure therapy (RPT) system, the vent adaptor comprising: a vent assembly comprising: a vent housing defining a central orifice for the flow of pressurized gas to pass through the vent assembly from the delivery conduit to the patient interface, the vent housing having an annular surface around the central orifice, and the annular surface having a plurality of holes to discharge pressurized gas to atmosphere; and a membrane positioned adjacent to the annular surface; a heat and moisture exchanger (HME); and a diffusing member.

Abstract: A fluid connector between patient interface and a respiratory therapy device and a vent adaptor for a respiratory pressure therapy system. The fluid connector comprising two parts, the first of which includes a seal and a latching portion and the second a complementary latching portion configured to engage the former to provide a fluid flow patch between the two parts. The vent adaptor comprising a vent assembly comprising a vent housing and an annular plate including an array of holes to discharge the pressurised gas to atmosphere and an deformable membrane which presses against the annular plate.

Abstract: A vent assembly for a respiratory pressure therapy (RPT) system. The vent assembly may include a vent housing having a first orifice configured to receive the flow of pressurized gas from the RPT device and the vent housing having a plurality of holes to discharge pressurized gas to atmosphere; a vent housing connector having a second orifice configured to direct the flow of pressurized gas to the patient interface; and a heat and moisture exchanger (HME) comprising an HME housing and an HME material within the HME housing, wherein the vent housing and the vent housing connector are configured to be connected to, at least in part, form a cavity, and wherein the HME is positioned in the cavity when the vent assembly is assembled.

Abstract: A vent system for use during respiratory therapy with a flow of pressurized gas may provide a continuous vent flow of gas. The vent system may include a vent housing having an outer wall; an inner wall, the inner wall defining an inlet for the flow of gas; and a base positioned between the outer wall and the inner wall, the base having at least one first orifice and at least one second orifice. The vent system may include a membrane, the membrane being shaped and dimensioned such that the membrane does not cover the at least one first orifice to allow the vent flow through the at least one first orifice, and the membrane being shaped and dimensioned such that in a first position the membrane is positioned over the at least one second orifice to allow the vent flow through the at least one second orifice.

Abstract: A patient interface includes a frame assembly (16100) including connectors operatively attachable to headgear, a cushion assembly (16175) including a shell (161800) and a seal-forming structure (16200) structured to form a seal with the patient's nose and/or mouth, and an air delivery connector (16600). The cushion assembly and air delivery connector are structured to releasably connect to the frame assembly independently of each other. A static face seal and separate static diametric seal between the shell (161800) and frame (16100). A dynamic face seal and separate dynamic diametric seal between the air delivery connector (16600) and frame (16100). Separate claims (FIG. 6) to a frame assembly (16100) with upper headgear connector arms (16134) including at least one slot (6146) (claim 17) or flexible portions (claim 22) to form hinges structured and arranged to conform to varying facial profiles.
