Abstract
An oxygen delivery conduit for supplying oxygen continuously under pressure (above atmospheric pressure) to a patient wearing a nasal cannula that prevents occlusion or pinching of the oxygen tube sections supplying the oxygen to insure a continuous oxygen supply to the patient. First and second oxygen supply tube sections rotate relative to each other freely while sealed to prevent crimping, pinching or occlusion of the tubing. The rotatable coupling includes roller or ball bearings mounted in a sealed, non-lubricated bearing structure in a coupling housing.
