## Abstract

A patient interface system includes a patient interface device, a conduit coupled to the patient interface device, and a gas supply assembly. The gas supply assembly includes a body portion having a first end, a second end disposed opposite and distal from the first end, a lower segment, and an upper segment attached to the lower segment. The first end includes a first coupling portion coupled to the patient interface device. The second end includes a second coupling portion coupled to the conduit. The upper segment and the lower segment together form an air channel extending between the first coupling portion and the second coupling portion. The first end is configured to be substantially disposed on the patient's forehead. The second end is configured to position the conduit away from the patient's face.
