Abstract:
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 (301), monitoring the patient for speech output (304), 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 (305).
Abstract:
A method of operating a device for treating sleep disordered breathing (SDB), wherein the device provides continuous positive airway pressure during sleep, includes determining whether treatment pressure at the patient interface is below a desired value (301), in response to the determining, increasing pressure generated by the flow generator (302), in response to the increasing, making a determination that the increase in flow generator pressure has resulted in less than a desired increase in treatment pressure at the patient interface (303), and in response to the determination, reducing or inhibiting further increase of the flow generator pressure (304, 306).
Abstract:
A CPAP or other ventilation system includes a mask (10), a flow generator (12), a positive or high pressure line (14) to provide positive or high pressure air from the flow generator (12) to the mask (10) and a vacuum or return line (16) provided to actively extract exhaled gas from the breathing chamber and/or the air delivery conduit of the mask (10). The vacuum or return line (16) includes a vent outlet preferably positioned remote from the mask (10).
Abstract:
A cushion assembly (700) for use with a respiratory mask includes a bladder (715) filled with the combination of a gel (740) having a first indentation hardness and a gel (750) having a second indentation hardness.
Abstract:
A patient interface includes at least one sub-component of headgear, headgear clips, frame, venting, forehead support, cushion, and elbow assembly constructed of TPE or the combination of a textile and polymer.
Abstract:
A patient interface (10) includes a sealing arrangement (20) adapted to provide an effective seal with the patient's nose, an inlet conduit arrangement (30) adapted to deliver breathable gas to the sealing arrangement (20), and a cover (40) that substantially encloses the sealing arrangement (20) and/or the inlet conduit arrangement (30).
Abstract:
A nasal assembly (10) includes a patient interface (12) including a hollow body (18) that defines an air chamber and a pair of nozzles (20) supported by the hollow body (18). Each nozzle (20) includes a conical tip (28) structured to sealingly communicate with a respective nasal passage of a patient's nose in use. Headgear (16) is provided to the patient interface (12) so as to maintain the patient interface (12) in a desired position on the patient's face in use. The hollow body (18) is bendable to adjust a position of the nozzles (20) 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 (14) to allow storage of the air delivery conduit. The at least one storage facilitating member (14) may be provided to the flow generator, a cradle (10), and/or the air delivery conduit.
Abstract:
A connector system (10) for use with an apparatus (12) that delivers a supply of pressurized breathable air to a patient includes an air delivery conduit (20) including an auxiliary conduit (22). The air delivery conduit (20) and auxiliary conduit (22) have a first end and a second end. A connector (30) is provided to at least one of the first and second ends. The connector (30) includes an inner tubular wall (34) and an outer tubular wall (36) surrounding the inner tubular wall (34) and being concentric with the inner tubular wall (34). The inner and outer tubular walls (34, 36) define first and second passages (38, 40) that are isolated from one another. One of the first and second passages (38, 40) is configured to communicate with the air delivery conduit (20) and the other of the first and second passages (38, 40) is configured to communicate with the auxiliary conduit (22).
Abstract:
A respiratory mask for continuous positive airway pressure treatment includes a cushion (80) adapted to be positioned against the face of a patient. The cushion (80) is configured in a gasket arrangement around an entrance to the airways of the patient. The cushion (80) is constructed from a polyurethane foam and has a thickness of greater than about 5 mm.
