A suction device for removing material from the trachea of a patient during ventilation comprising, a catheter having an internal lumen and opposed front and rear ends with the front end including a suction opening, front and rear couplings supporting the catheter and a protective sleeve normally enclosing the catheter and in turn connected to the front and rear couplings, the catheter is fixedly connected at its rear end to the rear coupling, the front coupling includes an internal seal for slidable receipt of the outer surface of the catheter. Thus, the catheter front end may be inserted into and withdrawn from the trachea of said patient. The rear coupling includes an irrigation port in turn communicating with the catheter lumen whereby lavage fluid may be injected into the port so as to wash the lumen and to directly irrigate the patient's trachea through said suction opening.
