A patient interface includes a sealing arrangement adapted to provide an effective seal with the patient's nose, an inlet conduit arrangement adapted to deliver breathable gas to the sealing arrangement, and a cover that substantially encloses the sealing arrangement and/or the inlet conduit arrangement.

Delivery of respiratory therapy

A headgear for use with a mask includes a first strap being configured to engage a back of a patient's head and extend on either side of the patient's parietal bone behind the patient's ears and assume, in use, a substantially circular or oval shape. At least a portion of the first strap is substantially inextensible. The headgear also includes at least one second strap configured to removably connect the first strap to the mask. The second strap may be more extensible than the first strap. At least a portion of the first strap is self-supporting such that the headgear maintains a three dimensional shape when not in use. The substantially inextensible portion of the first strap is constructed to resiliently return to a predetermined shape when not in use. The arcuate region includes a first portion that may be arranged to align substantially parallel with a top of the patient's head and a second portion being arranged to align substantially to a rear surface of the patient's head.

Headgear for masks

A flexible patient interface structure includes a posterior portion with at least one thin flexible membrane configured to form a seal with the patient's face in use. A wall thickness of the posterior portion is varied. An anterior portion of the flexible patient interface forms a chamber with the posterior portion and has a central gas washout vent region. A wall thickness of the anterior portion is thicker at the central gas washout vent region than at other adjacent regions. First and second laterally extending protrusions are configured to receive the breathable gas from an air delivery tube or air delivery tube connector. The central gas washout vent region is located between the first and second laterally extending protrusions and comprises an array of vent openings. Each of the first and second laterally extending protrusions terminates at a distal end that is furthest from the other laterally extending protrusion.

Respiratory mask

A patient interface is configured to deliver pressurized breathable gas to a patient's airways and includes a flexible cushion forming at least a portion of a plenum chamber. A pair of flexible receptacles are integrally formed with the flexible cushion and are formed on opposite lateral sides of the flexible cushion. Each flexible receptacle includes an inner wall that forms an opening configured to receive an air delivery tube and an outer wall that is radially offset from the inner wall. The outer wall extends laterally beyond the inner wall on a posterior side of the flexible receptacle and does not extend laterally beyond the inner wall on an anterior side of the flexible receptacle. The patient interface further includes a gas washout vent, a support structure that is attached to and is more rigid than the flexible cushion, and a pair of headgear connectors located on opposing lateral sides of the support structure.

A respiratory mask for continuous positive airway pressure treatment includes a cushion adapted to be positioned against the face of a patient. The cushion is configured in a gasket arrangement around an entrance to the airways of the patient. The cushion is constructed from a polyurethane foam and has a thickness of greater than about 5 mm.

An air delivery system for providing a supply of air from a source of air at positive pressure to an interfacing structure located at the entrance to the airways of a patient includes a manifold adapted to connect with the supply of positive air pressure and at least one tube connected to the manifold and adapted to deliver the supply of air to the interfacing structure. Each tube is structured to allow movement between an open phase in which the tube allows the passage of air and a collapsed phase in which the tube is collapsed. Each tube is structured such that weight of a typical patient's head against bedding apparel is sufficient to collapse the tube from the open phase to the collapsed phase.

Delivery of respiratory therapy using conduits with varying wall thicknesses

A respiratory mask for use with a patient, and that is suited for use with children, includes a flexible cushion arranged to interface with and deliver air to the patient's nose. The cushion has a tube connection portion at one or both sides adjacent the patient's nares, the tube connection portion being arranged to connect to an air delivery tube. This location, plus the very low profile of the mask, allows a patient (e.g. an infant) to sleep on their face more comfortably. A more rigid support structure adjacent the cushion is provided to stabilize the cushion and prevent it from collapsing. Headgear is also provided and arranged for releasable attachment to the support structure.

A patient interface assembly is configured to deliver pressurized gas to the patient's airways. The patient interface assembly includes a patient interface structure that is configured to sealingly engage the patient's face. The patient interface includes a receptacle. The patient interface assembly further includes headgear configured to support the patient interface structure on the patient's head. The headgear includes a clip that is receivable by the receptacle. The receptacle and the clip together form a multiple stage connection arrangement in which each of the multiple stages corresponds to an interlocked position of the clip in the receptacle. Each stage is associated with a corresponding range of headgear tension.

Headgear tensioning for respiratory mask

A cushion for a patient interface includes two or more bladders arranged in concentric relation. Each of the bladders includes a face-contacting portion adapted to engage the patient's face, and each of the bladders is adapted to be pressurized independently from one another. At least one of the bladders is an active bladder that is pressurized to at least a sealing pressure to form a continuous seal with the patient's face in use.
