Abstract: 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.

Abstract: A patient interface device includes a support structure, a pivot arm pivotably coupled to the support structure and structured to pivot about an axis, a patient coupling member, such as a mask or a forehead support, coupled to the pivot arm, and a cam wheel rotateably coupled to the support structure and engaging the pivot arm, wherein rotation of the cam wheel relative to the support structure and the pivot arm causes the pivot arm to pivot about the axis and the patient coupling member to move either forward or backward along a path of movement. Also, an alternative patient interface device includes a cam wheel rotatable about a cushion member that changes a position of a main body portion of the cushion member relative to a headgear frame member of the patient interface device.
