    摘要： Systems and methods relating to a face mask are described. An exemplar face mask includes: (i) a mask body including an interior side and an exterior side; (ii) inlet ports defined on the mask body; (iii) tubes designed to convey air flow or oxygen flow; (iv) tube transition features coupled to the tubes; (v) nasal prongs coupled to one of the tube transition features and designed to advance the air flow or the oxygen flow into nostrils; (vi) terminating features disposed around and for stabilizing the nasal prongs; and (vii) wherein either the tubes pass through the inlet ports such that portions of the tubes are present on the interior side or the tube transition features pass through the inlet ports such that portions of the tube transition features are present on the exterior side. An exhaust port and an exhaust tube remove exhaled air present inside the mask body.

    摘要： A gas-washout vent includes a housing with a first wall with one or more passages through the wall configured to provide fluid communication with a portion of the patient interface system exposed to a therapy pressure. The passages include respective first openings on a first surface of the first wall. The housing at least partially defines a second opening in communication with ambient atmosphere. A diffusing material is located at least partially within the housing to be adjacent the first surface. A surface of the diffusing material facing the first surface is spaced away from the first surface by a gap that extends to provide a fluid communication between all of the first openings and between all of the first openings and the second opening. The housing is configured so that air is prevented from flowing out of the housing at all areas directly opposite each of the first openings.

    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 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.
