ABSTRACT:
A flexible, cylindrical endotracheal tube is disclosed employing an axially slidable, hollow, cylindrical connector concentrically mounted upon the outer surface of the endotracheal tube near its proximal end. The proximal tip of the endotracheal tube is provided with an annular flange having an outer diameter larger than the inner diameter of the hollow output section of the slidable connector and smaller than the inner diameter of the hollow input section of the connector. A breathing circuit connector may be attached to the hollow input section of the slidable connector for coupling to the hoses of a conventional anesthesiology machine. The slidable connector is axially positionable over the outer surface of the proximal end portion of the endotracheal tube without loss of the airtight seal. The annular, flanged tip of the endotracheal tube may pass into and through the bore of the breathing circuit connector during positioning of the slidable connector. The axial positioning of the slidable connector may occur before intubation, after intubation, or while the patient is in recovery.
