<p>An improved eyeglass frame (30) and nasal cannula assembly for inconspicuously administering oxygen or other gases into the nostrils of a patient having repiratory ailments. The eyeglass frame (30) has a pair of grooves (38 and 38') 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 (40) fitted in these grooves (38' and 40). The nasal portion (10) of each of the cannula tubes (40) is adapted for insertion in one nostril of the patient's nose while the end of the free portion of each cannula tube (40) is connectable to a portable or stationary source of oxygen or other gas to be administered to the patient. The lower end (14) of the nasal portion (10) is shaped for retention in the user'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 (10) of the cannula tube (40), including the shaped lower end (14), is replaceable. To improve comfort and retention of the lower end (14) of the nasal portion (10) in the user's nostril, the groove (34 and 34') in the nosepiece of the eyeglass frame (30) is shaped to redirect the lower end (14) of the nasal portion (10) downwardly and inwardly toward the nostril. The overall appearance of the eyeglass frame (30) is substantially identical to that of a conventional eyeglass frame and all but a small portion of the cannula tubes (40) are hidden from view.</p> |
