An interface for positive pressure therapy includes a mask assembly, a headgear assembly and a connection port assembly. The mask assembly comprises a seal member that has an upper portion movably connected to an integrated lower portion, wherein the upper portion rolls during hinging movement of the upper portion relative to the lower portion. The headgear assembly allows connection to the mask assembly in a direction substantially normal to a direction of strap tension. The connection port assembly includes a swivel elbow with a valve member that controls flow through a port that opens toward the user. The valve member is provided with a tapered bead that helps prevent the valve member from sticking in a given position. Also, a connector for connecting a respiratory tube to an elbow connector. 本文披露了种用于正压治疗的接口，所述接口包括面罩组件、头戴具组件和连接端口组件。所述面罩组件包括密封构件，所述密封构件具有可移动地连接到集成下部部分的上部部分，其中所述上部部分在所述上部部分相对于所述下部部分铰接移动期间转动。所述头戴具组件允许在基本上垂直于带条张紧方向的方向上连接至所述面罩组件。所述连接端口组件包括具有阀门构件的旋转弯管，所述阀门构件控制穿过朝向用户开口的端口的流动。所述阀门构件设置有锥形珠缘，所述锥形珠缘有助于
