Abstract: A mask assembly adapted for use with a positive airway pressure device includes a mask frame, a cushion provided to the frame, a forehead support assembly, and a neck to connect the frame to the forehead support assembly. The neck includes at least one wall including a first edge and a second edge, wherein lower ends of the first edge and the second edge converge towards one another in an upward direction and upper ends of the first edge and second edge diverge from one another in an upward direction. The mask assembly is configured so that a relatively narrow portion of the neck overlies the bridge of the nose or is between the eyes of a user. The relatively narrow portion is a portion of the neck where a distance between the first edge and second edge is smallest.

Abstract: An elbow assembly for a mask system includes an elbow including a slot and a port, an anti-asphyxia valve adapted to be received within the slot and including a flap portion adapted to selectively close the port depending on the presence of pressurized gas, and a clip member to secure the anti-asphyxia valve to the elbow. The clip member includes a slot that is adapted to interlock with a protrusion provided to the anti-asphyxia valve.

Abstract: 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.

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: Systems and methods for selecting a mask system for a patient are provided. Certain example embodiments include generating 3D contours of patients and selecting mask systems based at least on these contours. These contours may be generated by using, for example, a cushion of translatable pins, a nasal cannular scanning device, and/or a shadow stereopsis sensor. Certain other example embodiments allow images and/or videos to be captured and optionally synchronized. Then, images of various mask systems may be overlaid to determine how well a mask system fits. In still other embodiments, a user can hold a transparency corresponding to a mask design in front of the patient's face to determine how well a mask system fits.

Abstract: A headgear assembly for a mask system includes a two-dimensional first headgear section and a two-dimensional second headgear section, wherein the two-dimensional first and second headgear sections are attached to one another to form a three-dimensional anatomically-shaped headgear assembly.

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 nasal mask assembly includes a relatively flexible cushion arrangement including a cushion that provides a breathing chamber and a face-contacting portion to form a seal around the patient's nose in use, an inlet tube supported by the cushion to deliver breathable gas into the breathing chamber for breathing by the patient, and three support members extending outwardly from the cushion. A relatively rigid frame is provided to a front side of the cushion arrangement. The frame includes three headgear attachment structures. Headgear includes three headgear straps engagable with the three support members and the three headgear attachment structures to maintain the cushion arrangement in a desired position on the patient's face.

Abstract: A mask system for use between a patient and a 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.

Abstract: Components of a CPAP or other patient ventilation apparatus have a remotely-readable identification tag encoded with component identification. data. The flow generator controller is programmed to receive data derived from the identification tag from a tag reader, and to adapt functions of the flow controller to coordinate with the component.
