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.

Abstract: An improved eyeglass frame and nasal cannula assembly for inconspicuously administering oxygen or other gases into the nostrils of a patient having respiratory ailments. The eyeglass frame has a pair of grooves in the rear surface of its front piece and a groove in the interior surface of each of its hinged temples. The nasal cannula assembly includes a pair of cannula tubes fitted in these grooves. The nasal portion of each of the cannula tubes is adapted for insertion in one nostril of the patient's nose while the end of the free portion of each cannula tube is connectable to a portable or stationary source of oxygen or other gas to be administered to the patient. The lower end of the nasal portion is adapted for retention in the use's nostril by a gentle gripping action of the ala of the nostril and also shaped for improved functioning and comfort. The entire nasal portion of the cannula tube, including the shaped lower end, is replaceable.

An eyeglass frame has a pair of grooves in the rear surface of its front piece and a groove in the interior surface of each of its hinged temples. A nasal cannula assembly comprising a pair of cannula tubes is fitted in the grooves. One end of each of the cannula tubes is adapted for insertion in one nostril of the patient's nose and the opposite end of each of the cannula tubes is connected to a portable source of supply of oxygen or another gas to be administered to the patient. The overall appearance of the eyeglass frame is substantially identical to that of a conventional eyeglass frame and all but a small portion of the cannula tubes are hidden from view.
