Flexible structure for mask, and method and apparatus for evaluating performance of a mask in use
摘要:
A respiratory mask includes a frame and a flexible structure provided to the frame and adapted to engage a patient's face. The flexible structure includes a chamber filled with a first gel and a second gel that is relatively harder than the first gel. A ratio of height of the first gel to the second gel in a lip region is in the range of about 0.25 to about 0.6.
