A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a front surface and a rear surface, opposite the front surface, and adapted in use to face the patient. The frame defines an inner wall and an outer wall extending from the rear surface, the inner and outer walls being spaced to define a channel therebetween. A cushion is removably attachable to the frame such that the cushion and frame are repeatably engagable with and disengageable from one another. The cushion includes a side wall to be inserted into the channel of the frame, the side wall having a first interlocking surface that engages a second interlocking surface provided in the channel when the cushion and frame are engaged with one another. The first and second interlocking surfaces interlock with one another to removably attach the cushion to the frame.

A method for treating a breathing condition includes providing a face strip having an adhesive layer and a mesh layer disposed on the adhesive layer and applying the adhesive layer to a mouth of a patient diagnosed with a breathing condition comprising at least one of a dry mouth, a sore throat, nasal congestion, or hypoxia. The method further includes covering the patient's mouth with the face strip and providing resistance from the face strip at the patient's mouth, and increasing nasal respiration with the face strip. The face strip reduces or prevents the incidence of the breathing condition.

A system for aligning a patient interface for use in delivering a flow of a breathing gas to the airway of a patient with an adhesive arrangement that is structured to secure the patient interface to the patient. The system includes a base that is structured to be disposed on a surface, the base having a central member protruding upward from the base to a contoured surface. The central member includes a pair of protruding alignment elements that extend further upward from the contoured surface and which are sized and structured to engage apertures in both of the adhesive arrangement and the patient interface in a manner which aligns such components with each other.

A conduit for delivering a supply of gas under a positive pressure includes a conduit wall having a first conduit end and a second conduit end. The first conduit end is adapted to be attached to the supply of gas. The conduit wall is deformable between (a) an open condition in which the conduit wall defines a conduit passage along which the supply of gas can travel between the first conduit end to the second conduit end, and (b) a collapsed condition in which the conduit wall substantially collapses the conduit passage.

A mask is disclosed that has a gas outlet which is quiet and provides for a diffused outlet flow of gases. The outlet is preferably a slot formed between a hollow body and cover over said hollow body. The mask also preferably extends and seals under a user's chin in use.

A cushion tension assembly for a respiratory interface device is provided. Cushion tension assembly includes an adjustment assembly and a number of tension members. Each tension member is operatively coupled to the adjustment assembly and is operatively coupled to the cushion body. In this configuration, the adjustment assembly is structured to move cushion body between a first configuration in which the cushion body provides a generally continuous seal, and a second configuration in which the cushion body provides a more complete seal.

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.

A mask is disclosed that has a gas outlet which is quiet and provides for a diffused outlet flow of gases. The outlet is preferably a slot formed between a hollow body and cover over said hollow body. The mask also preferably extends and seals under a user's chin in use.

A mask system for use between a patient and device to deliver a breathable gas to the patient includes a mouth cushion, a pair of nasal prongs, an elbow, and a headgear assembly. The mouth cushion is structured to sealingly engage around an exterior of a patient's mouth in use, and the pair of nasal prongs are structured to sealingly communicate with nasal passages of a patient's nose in use. The elbow delivers breathable gas to the patient. The headgear assembly maintains the mouth cushion and the nasal prongs in a desired position on the patient's face. The headgear assembly provides a substantially round crown strap that cups the parietal bone and occipital bone of the patient's head in use.

The present disclosure relates to an oxygen mask comprising: a mask body defining a cavity configured to be positioned over the mouth and nose of a patient, an oxygen port formed on the upper half of the mask body, an annular aperture formed on the mask body, and at least one vent port formed on the mask body, wherein each vent port is formed on the bottom half of the mask body in a manner that patient's exhaled gases are directed towards the vent port.
