Abstract
A mask system including a frame module and a cushion module provided to the frame module and adapted to form a seal with the patient's face. The cushion module includes a main body defining a breathing chamber and adapted to interface with the frame module and a cushion adapted to form a seal with the patient's face. The main body and the cushion are comolded with one another.
Claims18
A mask system for delivery of a flow of breathable gas at a continuously positive pressure to an entrance of a patient's airways, wherein the mask system is configured to maintain a therapy pressure in a range of about 2-30 cmH2O while the patient is sleeping to ameliorate sleep disordered breathing, the mask system comprising:
- a frame forming a breathing chamber pressurizable to the therapy pressure, the frame including an inlet opening structured to receive the flow of breathable gas at the therapy pressure for breathing by the patient;
- a cushion provided to the frame, the cushion constructed and arranged to form a seal with a patient's nose and/or mouth;
- a forehead support extending from a base of the frame positioned inferior the inlet opening;
- and
- a movement region provided at the base of the frame to couple the forehead support to the base of the frame, whereby the forehead support is coupled to the frame by the movement region only at the base of the frame, the movement region structured and arranged to allow automatic self-adjustment of the frame relative to the forehead support.

- a movement region structured and arranged to allow automatic self-adjustment of the frame relative to the forehead support;
- and
- headgear to maintain the mask system in position on a patient's head, wherein the forehead support comprises a pair of upper headgear connectors adapted to connect to upper headgear straps of the headgear,
- wherein the movement region is structured and arranged to maintain the seal of the cushion without the use of lower headgear straps.
