Abstract
Apparatus for delivering and scavenging anesthesia gas for a patient. A lower elongate piece forming a nose cannula for delivering gas, is removably secured generally parallel and immediately adjacent to an upper elongate piece for scavenging gas. The upper piece extends over a lower portion of the patient's nose, and has a plurality of openings disposed on a lower surface thereof, directed downward towards the patient's mouth. Both ends of the lower and upper pieces are provided with barbs for receiving corresponding supply and exhaust hoses at one end. Barbs at the other end are sealed by an end cap. A strap secures the apparatus on the patient's head. Thus the apparatus can be advantageously used with hoses on only one side of the face, thereby allowing the user to work with minimal obstruction on the opposite side of the face.
