Abstract
A wearable device (8,60,70,86) structured to exert a contact pressure between the wearable device and a skin surface of a wearer, such as a patient interface device for delivering a flow of breathing gas to a patient, includes a first member (18,72,96), such as a faceplate member, structured to have a first pressure applied thereto, a contact member (14,74), such as a sealing cushion, structured to exert the contact pressure against the skin surface in response to the first pressure, and a support member (20,62,78) positioned between the first member and the contact member, the support member including a plurality of compression members (40,52,54,64,84), wherein each of the compression members is structured to buckle in response to a compression force having at least a first predetermined level being applied to the support member.
