| 20090126739 | Interchangeable Mask Assembly - A system of breathing arrangements for delivering breathable gas to a patient includes at least first and second cushion components, e.g., full-face, nasal, nasal prongs, nose tip, and/or a combination of any of the above, including a nasal or full-face cushion and nasal prongs/nozzles combination, etc., that are different from one another in at least one aspect, and a common frame assembly configured to support each of the first and second cushion components. Various embodiments are directed to a full-face or nasal mask used with a frame having lateral connector portions having a stiffening member. The mask assembly may include a nose height adjustment device for the height of the cushion, or a cushion adjustment member by which the position of the cushion may be adjusted relative to the frame. The mask assembly may include a chin strap assembly. | 05-21-2009 |
| 20090205662 | Method and apparatus for improving cpap patient compliance - A method of operating a device for treating sleep disordered breathing (SDB), wherein the device provides continuous positive airway pressure during sleep, includes applying a treatment pressure to a patient, monitoring the patient for speech output, generating a signal in response to detected speech of the patient, and, in response to the signal, reducing the treatment pressure applied to the patient. | 08-20-2009 |
| 20090217929 | Delivery of Respiratory Therapy - 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. | 09-03-2009 |
| 20090277452 | Mask System - 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. | 11-12-2009 |
| 20090293875 | Acclimatization therapy for first time cpap and niv users - A method of acclimatizing a user to provide continuous positive airway pressure (CPAP) therapy, including operating a device for treating sleep disordered breathing (SDB) during successive treatment sessions, wherein the device provides continuous positive airway pressure during sleep, includes determining a clinically-derived full therapeutic pressure, applying a sub-therapeutic treatment pressure for the duration of a first session, obtaining responses to a series of pre-programmed patient and/or bed partner feedback questions before the start of a second session, and, based on the responses, either incrementally increasing the treatment pressure for the second session if the responses indicate that the patient is adjusting to therapy, or maintaining the treatment pressure for the second session if the responses do not indicate that the patient is adjusting to therapy. | 12-03-2009 |
| 20090320851 | NASAL PRONGS FOR MASK SYSTEM - A nasal prong for sealing with a nasal passage of a patient includes a head portion structured to seal and/or sealingly communicate with the patient's nasal passage and a column or stalk structured to interconnect the head portion with a base. The nasal prong is structured to redirect air flow direction, diffuse air flow or create turbulence, and/or orient a prong orifice in order to reduce and/or eliminate air jetting effects. | 12-31-2009 |
| 20100018534 | DELIVERY OF RESPIRATORY THERAPY - 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. | 01-28-2010 |
| 20100024811 | Bladder Cushion, Forehead Cushion, Headgear Straps, Headgear Cap and/or Chinstrap - 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. | 02-04-2010 |
| 20100132716 | Nasal assembly - A nasal assembly includes a patient interface including a hollow body that defines an air chamber and a pair of nozzles supported by the hollow body. Each nozzle includes a conical tip structured to sealingly communicate with a respective nasal passage of a patient's nose in use. Headgear is provided to the patient interface so as to maintain the patient interface in a desired position on the patient's face in use. The hollow body is bendable to adjust a position of the nozzles in use. | 06-03-2010 |
| 20100236549 | Elbow assembly - 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. | 09-23-2010 |
| 20100236552 | Cpap Systems - 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. | 09-23-2010 |
| 20110088699 | CUSHIONING STRUCTURE - A cushion assembly for use with a respiratory mask includes a bladder filled with the combination of a gel having a first indentation hardness and a gel having a second indentation hardness. | 04-21-2011 |
