A respiratory mask assembly includes a respiratory mask including a mask shell and a mask cushion, a forehead support adjustably coupled to the mask, and an angular adjustment member. The forehead support includes a joining member provided to the mask shell and a cushion frame pivotally mounted to the joining member. The cushion frame is adapted to be selectively locked against pivotal movement in at least three predetermined angular positions relative to the joining member by a tongue and slot arrangement. The angular adjustment member allows relative angular adjustment between the cushion frame and the joining member. The angular adjustment member includes a pair of flexible arms that are adapted to be flexed towards one another to disengage the tongue from a respective one of the slots, and releasing the flexible arms allows the flexible arms to resiliently flex away from one another to engage the tongue and the respective slot.

Forehead support for facial mask

A cushion comprises a substantially triangularly shaped frame from which extends a membrane. The membrane is spaced away from the rim of the frame, and its outer surface is of substantially the same shape as the rim. The seal forming portion thus contacts both the surface of the wearer's nose and a portion of the wearer's face. The shape of the seal forming portion is particularly suited to effectively seal the difficult region of the facial contour that is the crease between the sides of the nose and the face.

Mask and mask cushion therefor

A patient interface for use with the administration of CPAP therapy to a patient, comprising: a body for connection with a supply of pressurized breathable gas pressurized above ambient; and a compliant patient contacting element to communicate the pressurized gas to at least the patient's nasal passages, the element including a multilayered cushioning interface, the interface comprising an interior layer and an exterior layer being provided in spaced relation to the interior layer, the exterior layer being elastically and resiliently movable towards and away the interior layer in use. Along at least a portion of the perimeter of the exterior layer, a surface of the exterior layer is deformable from the spaced relation to abut against and contact against a surface of the interior layer in dependence at least in part on a deformation force applied to the exterior layer.

Patient interface

A full-face cushion comprises a frame and a membrane. The membrane has an aperture into which the wearer's nose is received. The membrane is spaced away from the frame. Respective notches receive the bridge of the wearer's nose. The wearer's nose and lips are received through the aperture into the chamber within the mask body. The seal forming portion thus contacts both the surface of the wearer's nose and a portion of the wearer's face in the region between the bottom lip and the chin, and around the sides and over the bridge of the nose.

Full-face mask and mask cushion therefor

A mask for use with the administration of CPAP therapy includes a mask body for connection with a supply of breathable gas pressurized above ambient; and a compliant patient contacting element including a multilayered cushioning interface. The interface has an interior layer and an exterior layer provided in spaced relation to the interior layer when the mask is not in use. The exterior layer is elastically and resiliently movable towards and away the interior layer in use. Only the exterior layer forms a contacting seal with the patient in use.

Mask

A cushion includes a substantially triangularly shaped frame from which extends a membrane. The frame has a scalloped edge by which the cushion is affixed to a mask body. The membrane has an aperture into which the wearer's nose is received. The membrane is spaced away from the rim of the frame. The wearer's nose is received through the aperture into the chamber within the mask body. The shape of the seal forming portion is particularly suited to effectively seal the difficult region of the facial contour that is the crease between the sides of the nose and the face.

Cushion and mask therefor

A respiratory mask assembly includes a respiratory mask and a forehead support secured to the mask via a joining member. The forehead support includes a cushion frame pivotably mounted to the joining member so as to be pivotably movable relative to the mask when the cushion frame is secured to the mask. At least one cushion is mounted on the cushion frame. A finger-operated adjustment control member is provided to the cushion frame. The finger-operated adjustment control member is manually manipulable to adjust a position of the cushion frame relative to the joining member along a predetermined path generally towards and away from the patient's forehead.

The present invention discloses an adjustable forehead support for a nasal or full-face mask wherein the forehead support may be adjusted for the different shapes and sizes of a facial profile. The forehead support utilizes a dual-arm system that adjusts the position of the forehead support vis-&#xe1;-vis the mask and/or airflow tube. The angle of the mask to the face may be adjusted with the present invention.

A full-face cushion (B) comprises a substantially triangularly shaped frame () from which extends a membrane (). The frame () has a scalloped edge () by which the cushion (B) is affixed to a mask body () to form a full-face mask (B). The membrane () has an aperture () into which the wearer's nose is received. The member () is spaced away from the rim () of the frame (), and its outer surface () is of substantially the same shape as the rim (). Respective notches () receive the bridge of the wearer's nose. The wearer's nose and lips are received through the aperture () into the chamber within the mask body ().

The shape of the seal forming portion () is particularly suited to effectively seal the difficult region of the facial contour that is the crease between the sides of the nose and the face.

A forehead support adapted to be secured to a respiratory mask includes a joining member for securing to the mask and a cushion frame pivotally mounted to the joining member. The cushion frame is adapted to locate one or more forehead cushions. The cushion frame is adapted to pivot relative to the joining member. The cushion frame is selectively lockable at two or more predetermined angular positions relative to the joining member.
