Abstract

See full text

A flexible patient interface structure includes a posterior portion with at least one thin flexible membrane configured to form a seal with the patient's face in use. A wall thickness of the posterior portion is varied. An anterior portion of the flexible patient interface forms a chamber with the posterior portion and has a central gas washout vent region. A wall thickness of the anterior portion is thicker at the central gas washout vent region than at other adjacent regions. First and second laterally extending protrusions are configured to receive the breathable gas from an air delivery tube or air delivery tube connector. The central gas washout vent region is located between the first and second laterally extending protrusions and comprises an array of vent openings. Each of the first and second laterally extending protrusions terminates at a distal end that is furthest from the other laterally extending protrusion.
