The faceplate portion has a main orifice and holes adjacent the main orifice. The device further includes a coupling conduit (6, 64, 164, 212) having an inlet end, an outlet end coupled to the inlet end, and a hood member having openings provided on an outer periphery thereof. The inlet end is structured to receive a flow of breathing gas. The outlet end is coupled to the main orifice to deliver the flow of breathing gas to the main conduit. The hood member surrounds the outlet end and is disposed over the holes such that exhalation gasses will through the holes and be captured by the hood member and directed through the openings.</p> |
