Forhead gas supply assembly for a patient interface system

A gas supply assembly for a patient interface system, the patient interface system including a patient interface device and a conduit for delivering a flow of breathing gas from a flow generating device to an airway of a patient, the gas supply assembly comprising:

• 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 including a first coupling portion structured to be coupled to the patient interface device, the second end including a second coupling portion structured to be coupled to the conduit, wherein the upper segment and the lower segment together form an air channel extending between the first coupling portion and the second coupling portion, wherein the first end is configured to be substantially disposed on the patient's forehead, and wherein the second end is configured to position the conduit away from the patient's face,
• a fluid coupling device having an inlet end and an outlet end, wherein the inlet end of the fluid coupling device is coupled to the conduit and the outlet end of the fluid coupling device is coupled to the second coupling portion,
• wherein the conduit has a diameter, and wherein the body portion including the air channel formed therein has a thickness which is substantially less than the diameter of the conduit such that the gas supply assembly has a low-profile relative to the patient's face, and wherein the fluid coupling device is an elbow.
