摘要：
595423 Disclosed is a mask assembly to supply breathable gas to a patient with adjustable forehead supports for improved comfort and sealing. The mask assembly comprises a mask frame； a cushion provided to the mask frame； and a forehead support. The forehead support comprises a frame connector extending from an upper portion of the mask frame and having an outer housing and an internal ring supported within the outer housing； an actuator disposed on the frame connector； and a forehead cushion support. The forehead cushion support comprises at least one forehead cushion support plate to carry at least one forehead cushion； and a tube having a distal end and a proximal end, the proximal end attached to the at least one forehead cushion support plate, the tube slidably attached to the frame connector along a linear adjustment path defined by the internal ring such that at least the distal end of the tube is enclosed within the housing in an extended position and a retracted position. At least two protrusions and at least two corresponding keyways are configured to prevent the tube from rotating about its longitudinal axis within the ring between the extended position and the retracted position. The actuator adjustably secures the tube to the frame connector along the linear adjustment path. Position markings are provided on the tube to indicate a position of the tube and include artwork formed by pad-printing, etching, laser-etching, and/or in-mold decoration.
