Abstract: A nasal cannula assembly comprises a nasal cannula with nostril outlet prongs and a pair of oxygen inlets. A pair of oxygen feed tubes at their one ends are connected to the cannula inlets and at their other ends adapted for connection to an oxygen source. Each of the feed tubes have ear contact points intermediate their ends adapted to be looped over the user's ears. A hollow cylindrical cuff of a soft resilient material is mounted over and around each inlet tube and extends between the cannula and the ear contact point to protectively engage the user's nose, face, cheeks and ears to prevent irritation.
