The mask cushion may be integrated with or coupled to a mask frame. The mask cushion typically includes an inner cushion component. The mask cushion also includes a patient facial-contact side portion with a chamber and a barrier to form the chamber that may be flexible. The chamber may serve as an outer layer with respect to the inner cushion component. The chamber may be partially or completely filled with a gas, fluid or gel. The inner cushion may be formed with a soft flexible material such as an elastomer or foam, etc. The barrier may be a membrane and may also be soft flexible material.

The textile tube includes an inner and outer layer that are joined along seams to form an air chamber or passageway. The textile tube can be pre-shaped so that the textile tube resiliently returns to a pre-determined shape prior to the introduction of pressurized air.

Abstract: An apparatus for humidifying a flow of pressurised, breathable air includes varying a first pressure of the flow of breathable gas to vary a level of thermal engagement between the conductive portion of the reservoir and the heater plate, varying a height of the variable portion varies a level of thermal engagement between the conductive portion of the reservoir and the heater plate, use of a humidifier reservoir base component with a maximum water capacity substantially equal to the predetermined maximum volume of water of the humidifier reservoir or the use of intersecting inlet and outlet axes.

Abstract: A patient interface for treating sleep disorder breathing includes a headgear tube that provides support for the seal forming structure. The headgear tube includes a patient-contacting portion and a non-patient contacting portion that are joined along seams to form a gas passageway. The headgear tube may comprise a textile material and/or a foam material. Portions of the headgear tube may be imparted with greater rigidity than other portions.

Abstract: A mask system and an air delivery conduit for use in the treatment of respiratory disorders. The air delivery conduit may comprise a textile having an airtight arrangement. A support structure may be provided to the conduit to provide form.

Abstract: A patient interface structure includes a cushion configured to sealingly engage the patient’s face and a front that is more rigid than the cushion. The cushion includes a forward opening, a rearward opening that is opposite the forward opening and a continuous sealing surface. The continuous sealing surface has a mouth sealing portion configured to seal around the patient’s mouth and a nasal sealing portion configured to seal around both of the patient’s nasal airways. The front plate includes an air inlet configured to both receive the pressurized respiratory gas and secure headgear to the patient interface structure. In addition, the nasal sealing portion includes at least one aperture that is separate from the rearward opening. Also, the front plate, the mouth sealing portion and the nasal sealing portion together form a common chamber.

Abstract: A mask system includes a frame adapted to attach headgear, a sealing arrangement releasably connectable to the frame, and an elbow provided to the sealing arrangement and adapted to be connected to an air delivery tube that delivers breathable gas to the patient. The sealing arrangement defines a breathing chamber and is adapted to form a seal with the patient's face. The sealing arrangement includes structure to establish a positive connection with the frame and with the elbow.

Abstract: A patient interface for delivering breathable gas to a patient includes a sealing portion adapted to form a seal with the patient and a support portion to which the sealing portion is mounted. A first headgear chord is connected to a first side of the support portion, and a second headgear chord connected to a second side of the support portion. Headgear is adapted to connect to the first and second headgear chords to secure the support portion to a head of the patient. At least one adjustment device on the support portion is adapted to selectively move the first and second headgear chords to tighten or loosen the headgear.

Abstract: Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The seal-forming structure may be constructed and arranged to form a seal with a region of the patients face surrounding an entrance to the patients airways for sealed delivery of a flow of air at a therapeutic pressure of at least 4 cmH2O with respect to ambient air pressure throughout the patients respiratory cycle in use. The positioning and stabilising structure may comprise a front hoop arranged to contact, in use, at least a region of the patients head superior to an otobasion superior of the patients head and a rear strap.

Abstract: A headgear or headgear segments are manufactured to shape thereby producing little or no waste material. Such headgear or headgear segments (components) may comprise a unitary, substantially seamless structure. Techniques such as knitting, braiding, crocheting, and 3D printing may be used to produce the headgear. As a result, the manufacturing process may have reduced steps, the amount of material waste may be reduced, and there are virtually no seams in the headgear between adjoining sections, thereby resulting in headgear with enhanced comfort.

Abstract: A patient interface assembly includes a flexible cushion with a nares sealing portion configured to sealingly engage the patient's nares and a mouth sealing portion configured to seal around the patient's mouth. A cushion clip is attached to the flexible cushion, forms at least part of a plenum chamber with the flexible cushion, and is more rigid than the flexible cushion. A frame is attached to the cushion clip, is more rigid than the flexible cushion. A superior portion of the frame extends beyond the mouth sealing portion in the superior direction to overlap at least a part of the pair of lateral nares engagement portions of the nares sealing portion. At least a part of the nares sealing portion of the flexible cushion is decoupled from both the cushion clip and the superior portion of the frame that overlaps the nares sealing portion so that the lateral nares engagement portions are movable independently of the frame and the cushion clip.
