摘要： 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.

摘要： A patient interface assembly is configured to deliver pressurized respiratory gas to a patient's airways. The patient interface assembly includes a cushion configured to sealingly engage the patient's face, a plenum base supporting the cushion, and a positioning and stabilizing structure configured to support the cushion and the plenum base on the patient's face. The positioning and stabilizing structure includes a stiffened portion. The patient interface assembly further includes a removable sleeve. The stiffened portion of the positioning and stabilizing structure is inserted into the removable sleeve. The removable sleeve is configured to be secured to the stiffened portion of the positioning and stabilizing structure by inserting a projection into a side cutout, and the stiffened portion of the positioning and stabilizing structure is prevented from sliding out of the removable sleeve when the projection is received within the side cutout.
