PATIENT INTERFACE DEVICE WITH TILT ANGLE ADJUSTING MECHANISM

摘要

A patient interface device (8) includes a cushion assembly (16) including a nasal cushion member (20), and a frame assembly (14) having frame member (48) having a first arm (54A) and a second arm (54B). The cushion assembly is rotatably coupled to the first and second arm such that the cushion assembly rotates with respect to the frame assembly about an axis extending through the first arm and the second arm. In addition, the frame assembly includes a drive mechanism (50) received and held by the frame member, the drive mechanism being operatively coupled to the cushion assembly such that actuation of the drive mechanism changes a tilt angle of the cushion assembly relative to the frame assembly.
