Abstract:
A patient interface device includes an elastomeric contacting portion that is structured to directly engage the skin of the user. The contacting portion has an engineered surface that includes a plurality of non-random, predesigned surface features designed to reduce friction and improve user comfort. In one implementation, the pitch between each immediately adjacent pair of the surface features is less than or equal to a predetermined maximum pitch value, and the height of each of the surface features is less than or equal to a predetermined maximum height value.
