A patient interface has a single loop head strap and a mask for covering at least the nostrils of the user. The single loop head strap extends from the mask at either end. A short length of supple conduit is coupled to the mask by a swivel or ball joint to allow rotation of the conduit relative to the mask through different angles and orientations.

Frame with supporting arms and length adjustable strap

A sealing interface includes an inner cushion and an outer sheath. The outer sheath substantially seals against the facial contours of the user. The inner cushion and the outer sheath each have a nasal bridge region, left and right cheek regions and either one of an upper lip region or a chin region. In use these regions are aligned with the corresponding nasal bridge region, left and right cheek regions and either the upper lip region or the chin region of a user. The inner cushion includes a hinged region. The hinged region is adapted to flex substantially independently of the inner cushion cheek regions.

Respiratory mask sealing interface

A breathing assistance apparatus for use with delivery of respiratory gases to a patient includes a patient interface, having a body section adapted to cover the nose, or nose and mouth of a patient and a sealing interface. The sealing interface includes at least an outer sealing member. The outer sealing member is adapted to attach to the body section in a sealing manner and has a substantially thin section in at least its nasal bridge region. The thin section is substantially thinner than the rest of the outer sealing member. The patient interface includes a mask body and a seal assembly. The seal assembly includes a flexible seal, and a rigid seal clip, the seal assembly being removably attached to the mask body via the rigid seal clip. The mask body and rigid seal clip are profiled to match the contours of a user's face so that the seal has a substantially constant wall depth.

Breathing assistance apparatus

Breathing assistance apparatus for treating sleep apnoea can include nasal interfaces for the supply of respiratory gases, but most particularly positive pressure gases are described. The nasal interfaces may include various forms of nasal pillows or nasal plugs. Associated elements, such as manifolds or housings to hold or secure the pillows or plugs or headgear, can be included.

The invention relates to a method of determining water level in a humidifier chamber that is part of a humidified gases delivery apparatus and system. The method comprising the steps of delivering power to a heater plate, varying the power delivered to the heater plate, measuring the rate of change of temperature and determining the level of water based on the heating characteristics of the volume of water within the chamber, in particular determining the level of water within the chamber based on the rate of change of temperature and the supplied power.

Humidified gases delivery apparatus and methods for controlling same

A mask assembly for use as part of an apparatus for supplying a flow of respiratory gases to a user is disclosed. The mask assembly includes a mask body having an inlet through which said flow of respiratory gases are provided to the interior of said mask body. A mask seal assembly comprising a seal of flexible material and a clip of rigid material is attached to the body. The seal has a first side and a second side. The first side of the seal is shaped to approximately match the contours of a user's face and in use substantially seal against a user's face. The second side is attached to the clip. The clip provides an interface extending substantially the full perimeter or periphery of the mask seal assembly for releasably attaching the mask seal assembly to the mask body. The clip comprises a bridging portion spanning outwards from the perimeter or periphery of the mask body to space at least a portion of the second side of the seal outwards from the perimeter or periphery of the mask body.

A breathing assistance apparatus is designed for use with delivery of respiratory gases to a patient. The breathing assistance apparatus includes a patient interface, having a body section adapted to cover the nose, or nose and mouth of a patient and a sealing interface. The sealing interface includes at least an outer sealing member. The outer sealing member () is adapted to attach to the body section in a sealing manner and has a substantially thin section () in at least its nasal bridge region. The thin section is substantially thinner than the rest of the outer sealing member.

An oral appliance includes an upper arched frame, an upper moldable tray coupled to the upper arched frame, a lower arched frame, and a lower moldable tray coupled to the lower arched frame. The upper arched frame includes a first tab and a second tab being positioned, with respect to each other, on opposite sides of a plane substantially bisecting the upper arched frame. The lower arched frame includes a third tab extending from the lower arched frame.

Oral appliance

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.

Mask

In one embodiment, a nasal cannula is shaped to fit within a user's nares, where the nasal cannula includes at least one prong allowing high flow delivery of humidified gases and creates positive airway pressure in the patient's airway. The prongs have angled ends such that, in use, gases flowing through the prongs are directed to the user's nasal passages. The nasal cannula body is partially swivelling and preferably has a ball joint connector. In another embodiment the nasal cannula may have at least one flared end prong that preferably seals within a patient's nare.

A respiratory interface, such as a mouthpiece, having a vestibular shield overlapping a user's teeth and gums, a gases passageway extending through the vestibular shield allowing for the passage of the gases through mouthpiece and an extra oral seal associated with the gases passageway, wherein the passageway in use causes gases to be diffused when exiting from the gases passageway. Mouthpiece may have an adjustment mechanism to alter distance between the vestibular shield and the extra-oral seal. The interface may include an elbow having a vent.
