Patent abstract
A nasal cannula that combines extremely flexible tubing and a novel vee-shaped nosepiece that fits the contour of the face and provides a stable footing and is self-righting because more than half its weight is below the tubing attachment points. Gas delivery prongs are molded at an angle relative to the body to direct gas into the center of the nostrils. The tubing is made from ultra-high molecular weight PVC resin with hardness between 40 and 75 Shore A.
