Abstract

A nasal cannula apparatus supported by a headband is disclosed for use by sleeping and by those desiring a comfortable arrangement. A pair of cannula tubes, having a connection to a supply of the gas to be administered, is led to a cannula junction supported by a headband. One tube of the pair extends on each side of the head of the wearer. The cannula junction may be positioned within the headband where the headband is tubular. In this case the tubes would extend through the headband. At the cannula junction the tubes may merely be secured, or they may terminate to sockets in the junction. From the cannula junction the tubes, or new separable tube ends, descend on either side of the wearer's nose and against the wearer's face, as directed by grooves in the cannula junction. The tubes are then curved more than 180 degrees to provide a biased grip to the ala of the nostrils, and then recurve a lesser amount so that the tube ends are not against the nostril tissues.
