Abstract
A tracheal tube assembly includes an outer cannula configured to be positioned in a patient airway and an inner cannula configured to be disposed inside the outer cannula. The tracheal tube assembly further includes a flange member secured about the outer cannula, and a connector coupled to a proximal end of the outer cannula. The connector is configured to provide a view of the inner cannula, and the inner cannula and the connector form a contiguous passageway for exchanging fluid with the patient airway in operation.
