摘要：
A patient interface device includes a cushion member having a main body portion having a surface structured to engage a face of a patient. A frame member is coupled to the cushion member, and a fluid coupling conduit is coupled to the frame member. An engagement member is coupled to the cushion member and a rotatable cam wheel is disposed between the frame member and the engagement member. Rotation of the cam wheel changes a position of the main body portion relative to the frame member. The cushion member includes a flexible portion adjacent the main body portion, and the cam wheel is rotatable about the flexible portion, such that rotation of the cam wheel about the flexible portion causes the flexible portion to deflect thereby moving the cushion member relative to the frame member.
