A patient interface system is disclosed. The 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. 公开一种患者接口系统。本发明还公开一种用于将正压空气供给输送到患者气道的入口以治疗睡眠障碍呼吸的患者接口结构，包括：密封形成部，其适于在患者的鼻子的下侧形成密封；基底部，其连接到所述密封上并且在使用时位于邻近上唇处；以及弹性结构，其位于所述密封形成部和所述基底部之间，所述弹性结构在邻近上唇的一侧相对较硬以便使所述基底部旋转离开上唇。
