A mask assembly for treating sleep disorder including: a first frame including a first wall that at least partially delimits a breathing chamber, a second wall surrounding an opening through the first wall and defining a first substantially cylindrical surface surrounding the opening, the second wall extending from the first wall, the opening allowing the flow of pressurized gas to the breathing chamber; a second frame including a third wall defining a second substantially cylindrical surface, a fourth wall, a member extending toward a forehead support and two headgear attachment locations, the third wall extending from the fourth wall, the second cylindrical surface at least partially overlapping with the first cylindrical surface, and the second frame being configured to removably interlock with the first frame proximate the opening; and a cushion molded to the first frame and adapted to seal around at least a patient's nose.

Disclosed is a respiratory mask comprising a mask body and an articulated connection piece that can be connected to a respiratory tube. On the mask body, at least one exhalation gap is located in the vicinity of a connection that holds the articulated connection piece. Preferably, the exhalation gap terminates in an umbrella-shaped outflow channel that runs away from the patient. Preferably, at least two components of the respiratory mask are interconnected without play.

A cushion for use with patient therapy may include a face contacting element having at least one portion including at least a first gel and a skin portion containing the first gel. The skin portion may be silicone based. The face contacting element may be substantially triangular, and at least one of the cheek regions and the lower region of the triangular face contacting element may include a concave section that curves inwardly towards the breathing chamber. The cushion may include first and second gels having one or more properties that are different from one another.

A face mask assembly (FMA) for supplying breathable gas to a wearer. The face mask assembly (FMA) includes a mask frame including a support, a facial cushion attached to the mask frame, and a forehead support. The forehead support includes a forehead cushion assembly and an adjustment knob operatively coupled to the forehead cushion assembly. The adjustment knob is threadably engaged with the forehead cushion assembly such that turning movement of the adjustment knob causes the mask frame to be moved between retracted and extended positions with respect to the forehead cushion assembly.

A breathing mask (200, 200. 200). The breathing mask (200, 200. 200) comprises: a frame (210, 210); a forehead support frame (230) which is connected to the frame (210, 210) pivotally to allow the forehead support frame (230) to shift toward the forehead (100) of a patient or shift away from the forehead (100) of the patient; and an adjusting member (220, 220, 220) which is connected to the frame (210, 210) rotatably and has an adjusting slope. The forehead support frame (230) has a joining part (235, 235) in contact with the adjusting slope so that the forehead support frame (230) is driven to rotate pivotally through the rotation of the adjusting member (220, 220, 220). Through the matching between the adjusting slope and the joining part (235, 235), the breathing mask (200, 200. 200) converts the rotation of the adjusting member (220, 220, 220) to the shifting of the forehead support frame (230); and through rotating the adjusting member (220, 220, 220), the height of the forehead support frame (230) relative to the forehead (100) of the patient can be adjusted. When the breathing mask is used, the forehead support frame (230) can be shifted by rotating the adjusting member (220, 220, 220) with a single hand, so that the patient can find the most comfortable position according to own feelings without help from others conveniently. The breathing mask is simple in structure and comprises a few parts; therefore, the manufacture process is simple, and the manufacture cost is low.

A breathing mask arrangement includes a mask frame, a sealing structure provided to the mask frame and adapted to form a seal with a patient's face, and a forehead support device movably mounted to the mask frame for adjustable movement with respect to the mask frame. The sealing structure is movably mounted to the mask frame for adjustable movement with respect to the mask frame, and the adjustable movement of the sealing structure is independent of the adjustable movement of the forehead support device.

A system for delivering a pressurized flow of breathable gas to a patient includes a patient interface configured to contact the patient's head. The patient interface has a frame and a cushion supported by the frame. The cushion is configured to sealingly connect the patient interface to the patient's face and form a chamber between the frame and the patient's face. The patient interface also has an inlet port in the frame to receive the pressurized flow of breathable gas. The system further includes a flow generator mounted on the patient interface. The flow generator is configured to generate the pressurized flow, capable of creating a pressure of about 2-40 cm H.sub.2O in the chamber. A flow generator housing houses the flow generator and is configured to reduce a transmission of vibration and/or noise generated by the flow generator to the patient interface. At least one support arm extends from the flow generator housing to the frame of the patient interface. The at least one support arm is connected to the frame of the patient interface by a soft joint.

Disclosed is a device for respiration which comprises at least of one body that delimits an inner chamber from an outer chamber, a region for sealing the device against parts of the face of a patient, fastening elements for positioning the device on the patient's head and a connection for supplying respiratory gas. The device is equipped with an actuator, which when adjusted, changes the distance of at least one part of the device from at least one part of the body of the patient.

A respiratory mask assembly for delivering breathable gas to a patient includes a frame to support one of at least first and second compliant patient interfaces and a forehead support adjustably mounted to the frame. The forehead support is structured and configured to be moved between a first position for use with the first patient interface and a second position relative to the frame for use with a second patient interface, whereby the forehead support maintains a horizontal offset distance with the first and second patient interfaces which is substantially constant.

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.
