A hollow cylinder designed to be inserted into an artificial opening made in the trachea (windpipe) during a tracheotomy to provide a patent airway. It is typically constructed of plastic and may include an inner cannula.
It is available in cuffed, uncuffed, and/or fenestrated versions, and in a variety of shapes and sizes to meet the individual needs of the patient. It is typically secured in position by a tracheostomy tube holder fastened around the patient’s neck. This is a single-use device.
