Forehead support adjuster for a mask, wherein the forehead support adjuster comprises at least a forehead support, consisting of support arm and cushion holder, a connection element, a rail with at least one guide groove, and a slide element, and wherein the slide element has at least one slide plate, at least one tenon and a guide element, wherein the at least one tenon is mounted rotatably and slidably in the at least one guide groove of the rail, and wherein the slide element is movably connected to the support arm. The forehead support adjuster is configured such that a movement of the slide element along the rail leads to a pivoting of the forehead support about at least one pivot axis D.

A patient interface includes a seal forming portion, a pad, and a cushion. The seal forming portion may have a base surface and a plurality of fibers fixed to and extending away from the base surface for contacting a patient's skin. The cushion may have at least along a portion of the circumference a first structure having an elongate section joined with at least one end section oriented substantially perpendicular or at an angle to the elongate section. A first end A of the elongate section may be connected or connectable to a frame member. The end section may be provided at an opposing second end B of the elongate section. The pad may have a resilient foam material layer with the seal forming portion. The pad may be adapted to be connected to the cushion.

An apparatus for providing a pressurised flow of breathable gas to the airways of a patient includes a pivotable outlet port structured and arranged to connect to an air delivery tube configured to pass the pressurised flow of breathable gas to a patient interface. The pivotable outlet port is able to pivot about at least one axis.

A mask system including a frame module and a cushion module provided to the frame module and adapted to form a seal with the patient's face. The cushion module includes a main body defining a breathing chamber and adapted to interface with the frame module and a cushion adapted to form a seal with the patient's face. The main body and the cushion are comolded with one another.

An elbow assembly for use in a respiratory mask, which includes an elbow, an inlet port, an exhaust port, and a baffle separating the inlet port from the exhaust port. A mask assembly includes a cushion comprising at least one gusset and an aperture for connection to the elbow assembly.

A patient interface device includes a support structure, a pivot arm pivotably coupled to the support structure and structured to pivot about an axis, a patient coupling member, such as a mask or a forehead support, coupled to the pivot arm, and a cam wheel rotateably coupled to the support structure and engaging the pivot arm, wherein rotation of the cam wheel relative to the support structure and the pivot arm causes the pivot arm to pivot about the axis and the patient coupling member to move either forward or backward along a path of movement. Also, an alternative patient interface device includes a cam wheel rotatable about a cushion member that changes a position of a main body portion of the cushion member relative to a headgear frame member of the patient interface device.

Disclosed is a method of forming at least a portion of a mask (4) that is structured to engage at least a portion of the face of a patient (52). The method can be generally stated as including employing at least a portion of a data set (74) that is stored on a machine-readable storage medium (72) and that is representative of the shape of at least a portion of the face in generating a configuration for an cushion element (24) of the mask. The cushion element is structured to extend from a support (20) of the mask and to have an engagement end (50) bopposite the support that corresponds with the shape of the at least portion of the face. The method can be generally stated as further including subjecting a workpiece (78) to a formation operation to cause at least a portion of the workpiece to be formed into the cushion element having the engagement end.

A respiratory mask assembly for delivering breathable gas to a patient includes a frame and an elbow assembly. The frame has a front surface and a rear surface adapted in use to face the patient. The frame includes a main body providing an aperture therethrough for the introduction of breathable gas into a nasal breathing cavity. The elbow assembly is swivelably coupled to the front surface of the frame. The elbow assembly includes a swivel elbow that defines an intake port and an exhaust port separated from the intake port using a baffle. The elbow assembly includes an end portion that interfaces with the aperture of the frame.

A mask assembly includes a mask frame including a lower portion and a neck extending from the lower portion, a cushion provided to the mask frame and adapted to contact a patient's face, a forehead support assembly provided to the neck of the mask frame, the forehead support assembly including a forehead support and a forehead pad provided to the forehead support, and an elbow assembly provided to the mask frame. The neck includes a pair of side walls spaced apart from one another along an entire length of the neck, the side walls providing an open space therebetween along the entire length of the neck that opens towards a front side of the mask assembly. The pair of side walls comprise an upper converging section wherein the pair of side walls converge towards one another in a downward direction.

A respiratory mask assembly including a frame and a cushion provided to the frame. The cushion including a non-face contacting portion removably attached to the frame and a face-contacting portion adapted to engage a patient's face. The face-contacting portion includes a side wall, a rim extending from the side wall and curving inwardly into a cavity of the cushion, and a membrane substantially surrounding the rim and including an inside surface spaced from an outside surface of the rim. The cushion includes a gusset portion extending radially outwardly from the side wall of the face-contacting portion and a reinforcing ring between the gusset portion and the face-contacting portion. The reinforcing ring is constructed and arranged to act as a stiffening hoop to reduce the tendency of the cushion to expand when under pressure.
