Abstract
The present invention provides in some embodiments, an endotracheal tube with subglottic secretion suction and a detachable suction line. The endotracheal tube is an elongate tube having an outer wall defining an elongate central lumen and an elongate suction lumen. An inflatable cuff is attached near a distal end of the elongate tube. The shoulder of the inflatable cuff is inverted in order to increase the diameter of the cuff from its distal end to its proximal end. The endotracheal tube also includes a connector to couple the suction lumen to a source of suction to remove subglottic secretions from the area above the cuff.
