摘要：
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.
