Abstract
A system for continuously supplying supplemental therapeutic oxygen to a patient to enhance atmospheric breathing comprising an oxygen supply source for continuously supplying low pressure low volume oxygen to a patient at relatively low pressures and relatively low flow rates to supplement normal atmospheric breathing; flexible oxygen supply tube devices for supplying oxygen from said oxygen supply source to the patient; and a continuous one-piece constant diameter flexible elongated tracheal tube member having a continuous constant diameter passage extending therethrough and being flexible when inserted into an operative position within the trachea to provide therein an intermediate curved side wall portion extending between a proximate end side wall portion having an unrestricted inlet opening therein located posterior of the neck of a patient and a straight distal side wall portion located in the trachea and extending downwardly therein and having an unrestricted distal end outlet opening located in upwardly spaced relationship to the bronchial tubes of the patient.
