  • Transtracheal catheter system and method
    Patent number: 5297546
    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 upwar
    Type: Grant
    Filed: September 4, 1990
    Date of Patent: March 29, 1994
