The DURATWIX® LINGO is a tracheostomy tube that can be used by tracheostomised patients. In order to be able to use the speaking function of the DURATWIX® tracheostomy tube, an additional speaking valve which can be attached to the 15 mm connector on the inner cannulas or an additional replacement fenestrated inner cannula with speaking valve (REF 19841/19842) is required. These items may, if required, be ordered separately.
