    摘要: A retractable tube for use in a respiratory apparatus for delivering a pressurized flow of breathable gas to a patient has an internal diameter of about 30 mm or less, a weight of about 500 g/m or less, and an unextended length of about 2 m or less. The retractable tube includes a portion that is extensible in a range of about 40%-400% in response to force applied to the tube, and the extensible portion is configured to return the tube to its unextended length in the absence of force applied to the tube. A respiratory apparatus for delivering a flow of pressurized breathable gas includes a flow generator to generate the flow and a patient interface to deliver the flow to the patient's airways. The flow generator and the patient interface are connected by a retractable tube. A method of delivering a flow of pressurized breathable gas includes connecting the flow generator and the patient interface using a retractable tube.

    摘要: 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.
