| 20090000623 | Reinforcing Member for a Patient Interface - A patient interface includes a frame, a cushion, and a reinforcing member. The cushion has a non-face-contacting portion connected to the frame and a face-contacting portion adapted to engage the patient's face in use. The face-contacting portion includes a side wall and a flexible membrane extending from the side wall. The reinforcing member is provided to at least a portion of an interior and/or exterior surface of the side wall of the cushion. The reinforcing member provides reinforcement to the side wall of the cushion to at least limit lateral expansion of the cushion in use. The reinforcing member may have a stiffness that is selectively varied along its length. | 01-01-2009 |
| 20090151729 | Nasal Assembly - A nasal assembly for delivering breathable gas to a patient includes a frame having lateral connector, a cushion with a pair of nozzles, and a clip to secure the cushion to the frame. The frame includes a vent channel and a plurality of vent holes. The frame/cushion includes structure (lugs/cut outs) to prevent the assembly of an unvented frame with an unvented cushion, for safety purposes. The frame includes cored portions that interface with corner lugs provided on the cushion. A patient interface includes a frame, a cushion (nasal mask, nasal-oro mask, nozzles, etc.) and a vent assembly including a pattern of vent holes including at least two rows. | 06-18-2009 |
| 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 |
| 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 |
| 20100043796 | SYSTEMS FOR REDUCING EXHALATION PRESSURE IN A MASK SYSTEM - An apparatus for improving patient comfort during CPAP therapy includes a venting arrangement arranged to reduce expiratory pressure. A mask system for providing CPAP therapy to a patient includes a mask; a flow generator to provide a flow of pressurised breathable gas; a tube to connect the mask to the flow generator; and a venting arrangement arranged to reduce expiratory pressure. | 02-25-2010 |
| 20100313891 | RESPIRATORY MASK - 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. | 12-16-2010 |
| 20100326445 | INTERFACE INCLUDING A FOAM CUSHIONING ELEMENT - A respiratory mask assembly includes a frame having a channel and a cushioning element including a clip portion adapted for interference seal and retention in the channel. The cushioning element includes an interfacing portion constructed from foam and having a wider width than the clip portion. | 12-30-2010 |
| 20110000492 | FOAM RESPIRATORY MASK - A patient interface for delivering breathable gas to a patient includes a foam interfacing portion adapted to provide a nasal interface to contact under and around the patient's nose in use and including an orifice adapted to surround both the patient's nares in use, and a positioning and stabilizing structure to support the foam interfacing portion in an operative position on the patient's face. The positioning and stabilizing structure is structured to provide a range of rotational, axial, and/or lateral movement to the foam interfacing portion while maintaining a sufficient interface and resisting the application of tube drag and/or headgear tension to the foam interfacing portion. | 01-06-2011 |
| 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 |
| 20110146684 | FOAM-BASED INTERFACING STRUCTURE METHOD AND APPARATUS - A cushioning component for use with a mask is constructed of foam material. A patient contacting surface, that is adapted to contact a patient, in use, has a rounded cross sectional profile and a base surface opposed to the patient contacting surface. | 06-23-2011 |
