Patent ID: 8596271

Claim:
A patient interface device comprising: a support member sized and configured to span at least a portion of a patient's face while remaining below the patient's eyes responsive to the patient interface device being donned by such a patient, the support member having a coupling portion configured to continuously span from a first side of a patient's face on a first side of the patient's nose to a second, opposite side of the patient's face on a second, opposite side of the patient's nose responsive to the patient interface device being donned by such a patient; and a sealing assembly operatively coupled to the support member at the coupling portion in a manner wherein the sealing assembly is rotatable relative to the coupling portion about a longitudinal axis of the coupling portion or slideable relative to the coupling portion along the longitudinal axis of the coupling portion while remaining in fluid communication with an interior of the support member, wherein the support member defines a gas carrying conduit adapted to carry a flow of gas to the sealing assembly, wherein the support member is a single-piece unitary member and includes a conduit coupling portion adapted to be coupled to a patient circuit, and wherein the conduit coupling portion is provided at a first end of the support member on a first side of the coupling portion, and wherein an exhaust assembly is provided at a second end of the support member on a second side of the coupling portion such that a continuous flow of gas is maintained from the first end of the support member to the second end of the support member through the coupling portion.
