The DURAVENT^® UNI LINGO PHON speaking cannula consists of an outer cannula and two inner cannulas, one of which has a push-on silver speaking valve. The speaking valve opens on inspiration and air can flow into the trachea. On exhalation, the silver valve closes and the air is directed towards the larynx for speaking. The inner cannula with a speaking valve features an oval opening, the so-called window.

The second inner cannula features a 15 mm connector, which enables the attachment of Heat and Moisture Exchangers (HMEs), so-called “artificial noses”.

The DURAVENT^® UNI LINGO PHON tracheostomy tube is also available as XL version.

Furthermore, a tube-holding strap is included in the scope of delivery.
