Patient interface device with customizable cushion

A cushion assembly for a patient interface device, the cushion assembly comprising:

• a cushion member including a first side structured to engage a patient's face, and a second side disposed opposite the first side;
• a plurality of plate members, the plate members being spaced apart from one another, thereby forming a groove in the cushion member between adjacent plate members;
• an adjustment mechanism for adjusting the position of the plate members, thereby changing the shape of the cushion member to generally conform to the patient's face, wherein the adjustment mechanism comprises a number of connecting members each connecting a plurality of the plate members together and including a securing mechanism, wherein the connecting members are adjustable to move the plate members, thereby changing the spacing of the groove disposed therebetween;
• and wherein the securing mechanism secures the connecting member and the corresponding plate members in the desired position;
• and
• a generally rigid center piece disposed in the interior of the cushion member,
• wherein the cushion member further includes a perimeter and a sealing flap disposed on the first side of the cushion member proximate the perimeter,
• wherein the plate members are directly coupled to the sealing flap to form an outer adjustment ring that generally extends around the center piece,
• wherein a second groove is formed between the center piece and the outer adjustment ring;
• and
• wherein the adjustment mechanism comprises a number of adjustment assemblies each extending between the center piece and a corresponding one of the plate members.
