The cushion-to-frame component includes a cushion side adapted to interface with the cushion component and a frame side adapted to interface with the mask frame. The cushion side includes a platform to engage and support the cushion component. The platform provides an engagement surface to engage the cushion component and inner and outer flanges provided to opposing ends of the platform to guide, support and/or retain the cushion component on the platform.

Abstract: A vent assembly is configured to discharge gas washout from a patient interface that is configured to receive a pressurized flow of breathable gas from a positive airway pressure device. The vent assembly includes a vent base configured to be attached to the patient interface and comprising a plurality of coplanar openings and a hydrophilic material positioned adjacent to the coplanar openings. The hydrophilic material is configured to wick water near the plurality of coplanar openings and/or capture moisture from a gas washout flow adjacent to the plurality of coplanar openings. In addition, the hydrophilic material is configured to release the accumulated moisture and/or water to the pressurized flow of breathable gas for breathing by the patient when the patient inhales.

The frame includes cored portions that interface with corner lugs provided on the cushion. A patient interface includes a frame, a cushion (nasal mask, nasal-oro mask, nozzles, etc.) and a vent assembly including a pattern of vent holes including at least two rows.

Abstract: A patient interface is configured to deliver a pressurized flow of respiratory gas to a patient's airways. The patient interface includes a cushion and shell assembly with a cushion portion mounted on a shell portion that is more rigid than the cushion portion. The cushion portion is configured to sealingly engage the patient's face and has a vent opening. The shell portion includes a plurality of headgear connectors. The patient interface further includes a gas washout vent assembly configured to be positioned within the vent opening of the cushion portion. The gas washout vent assembly includes a main body configured to be secured to the cushion portion, a porous body, and an outer cover with a plurality of openings. The main body at least partially houses the porous body and the outer cover.

Abstract: A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient's face.

Abstract: A nasal assembly for delivering breathable gas to a patient includes a frame having lateral connector, a cushion with a pair of nozzles, and a clip to secure the cushion to the frame. The frame includes a vent channel and a plurality of vent holes. The frame/cushion includes structure (lugs/cut outs) to prevent the assembly of an unvented frame with an unvented cushion, for safety purposes. The frame includes cored portions that interface with corner lugs provided on the cushion. A patient interface includes a frame, a cushion (nasal mask, nasal-oro mask, nozzles, etc.) and a vent assembly including a pattern of vent holes including at least two rows.

Abstract: A respiratory mask for continuous positive airway pressure treatment includes a cushion adapted to be positioned against the face of a patient. The cushion is configured in a gasket arrangement around an entrance to the airways of the patient. The cushion is constructed from a polyurethane foam and has a thickness of greater than about 5 mm.

Abstract: A vent arrangement is provided to a mask or associated conduit to discharge exhaled gas from the mask to atmosphere. The vent arrangement is structured to diffuse the exhaust vent flow to produce less air jetting, thereby increasing the comfort of the patient and their bed partner. For example, the vent arrangement may include one or more grill components and/or media constructed and arranged to diffuse vent flow.
