Abstract: A patient interface system for delivering a flow of breathable gas to a patient includes a patient interface structure configured to sealingly engage the face of the patient and a retaining element configured for application to the patient. The retaining element is configured to support the patient interface structure in sealing engagement with the face of the patient. The retaining element includes an adhesive and/or at least one strap. In addition, the patient interface structure is configured to be released from and re-engaged with the retaining element for re-positioning of the patient interface structure relative to the patient's face in a plurality of positions while the retaining element remains supported by the patient.

Abstract: A PAP system is adapted for treatment of respiratory disease or sleep disordered breathing and includes a headgear adapted for engaging a patient's head. The PAP system also includes a patient interface adapted to be secured to and sealed against a portion of the patient's face, in use, by the headgear. The PAP system further includes a flow generator adapted to be connected to the patient interface. The flow generator is adapted to be secured by a portion of the headgear to the patient's head. In addition, the flow generator includes a blower adapted to provide pressurised breathable gas to a patient through the patient interface. The blower is at least partially vibrationally isolated from the patient's head by at least one foam layer mounted within the flow generator to secure the blower. The at least one foam layer is adapted to reduce the amount of transmitted vibration received by the patient.

Abstract: A patient interface system for delivering a flow of breathable gas to a patient includes a patient interface structure configured to sealingly engage the patient's nares; a pair of strips configured to be connected to opposite sides of the patient interface structure; and adhesive configured to secure the patient interface structure in sealing engagement with the patient's nares. The adhesive may be provided on the strips, and the strips are configured to be adhered to sides of the patient's nose by the adhesive.

Abstract: Systems, devices and methods of use adapted for treatment of respiratory disease or sleep disordered breathing include a patient interface (10) adapted to be secured to and sealed against a portion of a patient's face, in use. A flow generator is adapted to be connected to the patient interface and to be secured by a portion of the patient's body. The flow generator includes a blower (50) adapted to provide pressurized breathable gas to a patient through the patient interface. The blower is adapted to be at least partially vibrationally isolated from the patient's body by at least one dampening system (49) or device. The dampening device or system is adapted to reduce the amount of transmitted vibration received by the patient. A PAP system includes a patient interface including sealing arrangement (30) adapted to form a seal with the patient's nose and/or mouth and headgear (40) to support the sealing arrangement in position on the patient's head.

Abstract: A patient interface system for delivery of a supply of air at positive pressure to the entrance of a patient's airways for treatment of sleep disordered breathing includes an air delivery tube connected to a flexible portion of a plenum; a vent structure having sufficient rigidity to support its own weight under gravity and/or not to block or fold under tube movement or tube drag; and a patient interface structure. The patient interface structure includes a seal forming structure arranged on a top portion of the plenum; and a seal positioning and stabilizing structure connected to a flexible portion of the plenum. The seal-forming structure is substantially decoupled from a tube drag force.

Abstract: A respiratory assistance component is disclosed that changes shape when an electrical charge is provided. The amount of electrical charge that is applied may be based on values, characteristics, or user controlled parameters of the respiratory assistance system. The component may be all or part of a patient interface, a tube, a flow generator, and/or a sleep mat.

Abstract: A patient interface system for delivering breathable gas to a patient includes a patient interface configured to sealingly engage the patient's face. A mechanism may be provided to ensure that an effective seal is maintained between the patient interface and the patient's face by preventing, reducing, minimizing or limiting effects of disruptive forces, such as tube drag, on the patient interface.

Abstract: A PAP system includes a PAP device to generate a supply of pressurized air, a patient interface adapted to form a seal with the patient's face, air delivery tubing to interconnect the patient interface and the PAP device, and a cover that substantially encloses at least a portion of the PAP device and a portion of the air delivery tubing. The cover allows the PAP device to be carried by and/or supported on the patient's head.

Abstract: An air delivery conduit (620) includes first (621) and second (622) conduit portions that cooperate to form the conduit, each conduit portion including an inner layer of a film laminate (650) that forms an interior surface of the conduit and an outer layer of a textile (655) that forms an exterior surface of the conduit.

Abstract: A headgear for use with a patient interface for delivering a flow of breathable gas to a patient includes at least a strap adapted to position the patient interface in sealing engagement with the patient's airways. The strap is constructed from an elastomer and a first side of the strap includes a first region on a portion of its surface that is textured to reduce friction with objects contacting the strap. A textured surface coating for a portion of an elastomer strap included in a headgear system is adapted to contact the skin of a patient, when in use, and the coating has a Ra value greater than zero. A vent for use with a patient interface for delivering a flow of breathable gas to a patient includes a plurality of rises and runs in a stepped arrangement; and a plurality of holes in the stepped arrangement for the venting of gas.

Abstract: A mask system and an air delivery conduit (200) for use in the treatment of respiratory disorders. The air delivery conduit (200) may comprise a textile (220) having an airtight arrangement. A support structure (240) may be provided to the conduit to provide form.

Abstract: A headgear for use with a patient interface for delivering a flow of breathable gas to a patient includes at least a strap (741) adapted to position the patient interface in sealing engagement with the patient's airways. The strap is constructed from an elastomer and a first side of the strap includes a first region (215) on a portion of its surface that is textured to reduce friction with objects contacting the strap. A textured surface coating for a portion of an elastomer strap included in a headgear system is adapted to contact the skin of a patient, when in use, and the coating has a Ra value greater than zero. A vent (500) for use with a patient interface for delivering a flow of breathable gas to a patient includes a plurality of rises (580) and runs (570) in a stepped arrangement; and a plurality of holes (510) in the stepped arrangement for the venting of gas.

Abstract: A PAP system adapted for treatment of respiratory disease or sleep disordered breathing includes headgear adapted to engage a patient's head, a patient interface adapted to be secured to and sealed against a portion of a patient's face, in use, by the headgear, a flow generator adapted to be connected to the patient interface, and wherein the flow generator is adapted to be secured by a portion of the headgear to the patient's head, and an outlet tube to interconnect the flow generator and the patient interface. The patient interface includes a frame and a sealing arrangement supported by the frame. The sealing arrangement includes a seal portion, a body portion, and an inlet tube in communication with the outlet tube. The frame and the outlet tube are constructed of a relatively rigid material.
