Abstract
An oxygen supply, hood for administering oxygen to a patient, departs from the enclosed masks and enlarged, open face shields, of the prior art by being formed as a unitary shell with a central dome, forming an open bottom, mixing chamber extending outwardly above the level of the mouth. The incoming oxygen forms a whirlpool, or vortex, within the chamber which mixes oxygen with moist exhaled air and permits the moist oxygen to also reach the mouth. The shell is firmly affixed by a recess over the bridge of the nose, by a strap across the upper lip and by a pair of integral wings, extending along the cheek bones to a band around the head. The gas delivery tube, within the mixing chamber extends under the nostrils, and along the upper lip of the patient. The gas discharge nozzles on the tube are directed only upwardly and outwardly, away from the nose and mouth, toward the inside face of the front wall of the shell.
