摘要：
Disclosed is a CPAP breathing mask system with a headgear and cushion module and a seal and frame module that provide a better air-tight seal between the mask and the user&rsquo；s face. The cushion and headgear module includes a one piece construction having an outer fabric layer and an inner cushioning layer encapsulated within the outer fabric layer. The cushion and headgear module includes a cushion region adapted to define a breathing chamber and form a seal with the patient&rsquo；s face and a headgear region including straps adapted to maintain the cushion region in position on the patient&rsquo；s face in use. The outer fabric layer and the inner cushioning layer in the cushion region are positioned about or around the patient&rsquo；s airways to define the breathing chamber and form the seal around the patient&rsquo；s airways. A tube connector is provided to the cushion region and adapted to communicate with air delivery tubing. The cushion region includes a first softer layer of foam and a second harder layer of foam and at least a portion of the cushion region is coated or otherwise sealed to create an air impermeable seal. The cushion and headgear module is cut by ultrasonic die cutting to provide the cushion and headgear module with substantially rounded edges. The cushion region includes a structural component to provide structural stiffness and support to the inner cushioning layer.
