Abstract:
A mask for delivery of respiratory therapy to a patient may include one or more of the following improvements: rigidizer provided to headgear strap, locking clip/clip receptacle headgear connection, keyed headgear buckles, lotion dispenser on frame, rotatable prongs to adjust orientation, alignment indicators provided to prong, cushion and/or frame, chin flap with bellows arrangement, vent holes positioned away from gas entry port, and vent holes to direct washout gas at an angle.
Abstract:
A breathing apparatus includes components, including, but not limited to, a flow generator, a patient interface, and a delivery conduit. A connector for connecting components of the breathing apparatus includes a male connector, including a recess, extending from a first component, and a female connector, including a lever pivotally connected thereto, extending from a second component. A switch indicates a connection state of the connector. The switch includes a ring provided in an end of the first or second component and the ring includes a projection extending through an aperture in the end of the first or second component. The projection is movable between a first position and a second position to indicate the state of the connector.
Abstract:
A method and apparatus for humidifying breathable gas provided to a user includes providing a breathable gas, producing moisture or water derived from ambient environmental surroundings, e.g., via condensation and/or dehumidified air, and directing the breathable gas along an air flow path. The air flow path optionally includes access to at least a portion of the moisture or water for increased humidification of the breathable gas, for delivery to the user.
Abstract:
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.
Abstract:
A mask assembly for delivering breathable gas to a patient may include a patient interface structured to engage the patient's face and provide a seal, a headgear arrangement to support the patient interface in a desired position on the patient's face, and an audio unit provided to at least one of the patient interface and the headgear arrangement. The audio unit may be operable to selectively generate at least one sound.
Abstract:
A CPAP system includes a flow generator, a patient interface, an air delivery conduit that interconnects the flow generator and the patient interface, and a packaging arrangement including at least one storage facilitating member to allow storage of the air delivery conduit. The at least one storage facilitating member may be provided to the flow generator, a cradle, and/or the air delivery conduit.
Abstract:
An adapter for use with a flow generator includes a conduit attachable to the outlet of the flow generator and an identifying element supported by the conduit and providing an identifying feature unique to a specific peripheral component attachable to the flow generator. The identifying feature is communicatable to the flow generator so that appropriate operating parameters of the flow generator may be automatically selected by the flow generator to coordinate with the specific peripheral component.
Abstract:
A comfortable low-leak mask assembly for use with Non-Invasive Positive Pressure Ventilation (NIPPV) is provided to improve patient compliance and/or treatment. The mask system may include headgear having straps that are substantially inextensible and/or micro-adjustable; and/or a mask and/or cushion that includes various structures to allow enhanced/tailored sealing and/or fit at selected locations on the patient's face.
Abstract:
A continuous positive air pressure (“CPAP”) or ventilator system includes a mask and an air flow generator. The air flow generator is mounted or provided to the mask's wearer. In one embodiment, air flow generator is mounted on the mask.
Abstract:
Methods and/or apparatuses for treating sleep-disordered breathing (SDB) are provided. In particular, systems and/or methods are provided which may temporarily boost the pressure of a supply of breathable gas provided by an AutoSet device for the treatment of hypopnea. In certain example embodiments, a supply of breathable is provided to patients to treat apneas and/or hypopneas. The presence and/or absence of apneas and/or hypopneas are detected (e.g. by monitoring the Apnea-Hypopnea Index). When hypopnea events are detected, the pressure of the supply of breathable gas temporarily is increased above the Pcrit and/or CPAP levels, at least during patient inspiration. When the hypopnea events are normalized, the pressure is reduced. In certain example embodiments, the pressure will not be increased when a non-hypopnea event is detected at the same time as a hypopnea event.
