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 full-face cushion for a patient interface that delivers breathable gas to a patient includes a frame connector adapted to engage the cushion with a mask frame. A clip is provided to maintain the cushion to the frame. The clip includes clip portions that connect to the frame with a snap-fit.

Cushion and cushion to frame assembly mechanism for patient interface

A forehead support for a patient interface used in the treatment of sleep disordered breathing, includes a support post provided to a frame and a pair of arms extending from the support post. At least one of the pair of arms is adapted to rotate relative to the support post about an axis that extends transverse to the support post.

Forehead support for a patient interface

Mask system includes frame, cushion, cushion clip, swivel elbow, headgear and/or headgear clips configured for use in a clinical or hospital environment. One or more components of the mask system configured to promote single patient use, for example, by providing an age indicator and/or preventing disassembly and/or cleaning.

Mask system

An elbow assembly for a mask assembly includes an anti-asphyxia valve (AAV) assembly that may take the form of a box-like frame work, a drop-in arrangement, or a slot-in arrangement. In each case, the AAV assembly may include a flap element which is movable so as to either direct ambient gas/air to the elbow assembly and thus the patient using the mask assembly, or to allow the passage of pressurized gas to the patient.

Anti-asphyxia valve assembly for respirator mask

A cushion for a patient interface includes an outer membrane providing a sealing structure adapted to form a seal with the patient's face in use and an underlying membrane generally spaced away from the outer membrane. The underlying membrane provides a support structure for the outer membrane. The outer membrane and the underlying membrane each have an inner edge which defines an aperture to receive the patient's nose in use. The underlying membrane is segmented along its inner edge.

Cushion for a patient interface

A full-face cushion for a patient interface that delivers breathable gas to a patient includes a frame connector adapted to attach the cushion to a mask frame and an interface provided to the frame connector. The interface is constructed of foam and defines a cushion cavity. The interface includes a foam contact surface adapted to interface or contact with surfaces of the patient's face in use.

A mask assembly includes a forehead support having a base provided to a frame and at least one, and preferably two upwardly extending support arms. The arms define a fixed or an adjustable included angle that is preferably less than 180&#xb0; and, in the range of about 100&#xb0;-150&#xb0;. The arms can be attached either directly to headgear straps, or the arms can be connected to headgear straps via clips.
