Trachie-Voice Speaking Valve, Insight Medical
It has a one-way mechanism that opens when the patient breathes in, allowing air into the airway via the tracheostomy. The valve closes on expiration allowing air to follow the normal route of expiration through the mouth and nose, instead of the tracheostomy, permitting speech.
