A full-face mask assembly includes a frame and a cushion provided to the frame. The cushion is adapted to form a seal around the patient's nose and mouth. A flexible lip is provided to an interior wall of the cushion. The flexible lip is adapted to engage the frame to provide a seal in use.

Cushion/frame sub-assembly connectable to outer frame

A cushion/frame assembly for a patient interface includes a cushion frame and a cushion. The cushion frame includes a cushion frame material, an annular wall portion having an opening that extends along a cushion frame longitudinal axis, and a projection extending radially with respect to the opening. The cushion frame is configured to snap fit with an outer frame having headgear attachment points and being configured to engage an inlet conduit. The cushion is connected to the cushion frame. The cushion is structured to form a seal with the patient and includes a cushion material that is more flexible than the cushion frame material.

Cushion/frame assembly for a patient interface

A cushion for a respiratory mask assembly includes a frame-connecting portion, a face-contacting portion, and a gusset portion disposed between and joining the frame-connecting and face-contacting portions. The gusset portion includes at least one perimetrical region which includes a laterally projecting exterior gusset section and a laterally projecting interior gusset section.

Respiratory masks with gusseted cushions

A patient interface includes a shell with a central opening configured to receive the pressurized flow of air, a foam cushion, and an elastomeric support portion that is attached to the shell, supports the foam cushion, and forms at least part of a chamber together with the shell and the foam cushion. The elastomeric support portion includes a side wall that forms a continuous perimeter around the chamber and a resiliently flexible lip that supports the foam cushion and extends from the side wall toward an interior of the chamber. The resiliently flexible lip has an outer perimeter that is anchored to the side wall and an unsupported inner perimeter. The foam cushion overhangs the inner perimeter of the resiliently flexible lip, and the shell is more rigid than the elastomeric support portion. In addition, the foam cushion is configured to directly contact and engage a portion of the patient's skin in use.

Mask and components thereof

Cushion to frame assembly mechanism

A cushion for a patient interface that delivers breathable gas to a patient includes a base wall structured to be connected to a frame, an underlying support cushion extending away from the base wall towards the patient's face in use, and a membrane provided to substantially cover at least a portion of the underlying cushion. The membrane is adapted to form a continuous seal on the patient's face. The underlying cushion has a spring-like connection with the base wall. The underlying cushion and/or base wall define a spring constant that varies along a length of the seal.

Cushion for patient interface

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.

Mask assembly

A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a cushion. The cushion has a non-face contacting portion structured to be connected to the frame, a face-contacting portion structured to engage the patient's face, and a central portion that interconnects the non-face contacting portion and the face contacting portion. The frame may be structured to allow a forehead support to assume multiple positions, to compensate for replacement cushions that may have a different profile, shape or size. The cushion is structured to compensate for variations in strap tension, treatment pressure and/or movement of the patient. Headgear may be provided with a strap assembly in which one or more straps is provided with selectively adjustable elasticity or extensibility that may be automatically changed in dependence of treatment pressure and/or treatment type.

Cushion for a respiratory mask assembly

A nasal prong () for sealing with a nasal passage of a patient includes a head portion () structured to seal and/or sealingly communicate with the patient's nasal passage and a column or stalk structured to interconnect the head portion with a base. The head portion () is configured to direct gas in use away from the septum and/or posteriorly relative to the nasal passage.

Nasal prongs for mask system

A patient interface assembly includes a cushion and frame assembly with a cushion portion and a frame portion that together form a breathing chamber. The frame portion includes an anterior aperture configured to receive the flow of breathable gas. Headgear includes a back portion, a pair of upper headgear straps extending from the back portion, and a pair of lower headgear straps. The patient interface assembly also includes a shroud in the form of a contoured plate. The shroud is removably mounted on the frame portion by way of a snap-fit connection and includes a pair of lower headgear connectors. The patient interface assembly also includes a forehead support extending from the shroud and having a free end with an upper headgear connector. The forehead support has a first curvature that curves in a first direction around an axis that is offset from the patient interface assembly and extends along a length of the forehead support.
