Abstract
This invention relates to tracheostomy tubes and particularly to a tracheostomy tube construction and a system incorporating a talking tracheostomy tube. A pneumatic vibrator is provided for generating sonic vibrations. A tracheostomy tube includes a main airway and secondary airway. The secondary airway extends generally along the main airway for a substantial portion of its length. Furthermore there is an entryway to the secondary airway outside the entrance of the tracheostomy tube into a tracheostomy. And an exit from the secondary airway adjacent its end remote from the entryway. A source of compressed air is coupled to the pneumatic vibrator and the pneumatic vibrator coupled to the entryway to supply air containing sonic vibrations to permit the wearer of the tracheostomy tube to articulate audibly comprehensible speech.
