The present invention relates generally to apparatus and methods used in trans-tracheal oxygen therapy to permit a micro-tracheal catheter to be inserted into the throat, so that breathing efficiency may be enhanced through the introduction of a continuous stream of oxygen directly into the patient's lungs. More particularly, this invention relates to an adapter for use on the outer end of the micro-tracheal catheter to connect the micro-tracheal catheter to an oxygen source through an oxygen supply hub while simultaneously and selectively permitting the introduction of a saline solution or other material into the patient's lungs through a second material supply hub. During the introduction of solution into the lungs, no oxygen is lost, and the stream of oxygen remains continuous.
