Tritube, Ventinova’s completely new and innovative small bore endotracheal tube, now available for you!


With an outer diameter of only 4.4mm OD, Tritube is an ultra-thin ventilation tube intended to be used for obtaining endotracheal access to the airway and ventilating an adult patient with EVA technology (Expiratory Ventilation Assistance).




Tritube can be used together with Ventrain, the manual small lumen ventilator, and has three lumens:

  1. ventilation lumen – with Murphy eye and an inner diameter smaller than 3mm
  2. cuff lumen – to inflate and deflate the high volume low pressure cuff
  3. intratracheal pressure measurement lumen – for continuous intratracheal pressure measurements


The combination of Tritube and Ventrain provides a solution for anesthesiologists and surgeons in the field of upper airway surgery and oral surgery, providing:

  • easy access to the airway;
  • effective ventilation;
  • a secured airway;
  • a hygienic and clear sight for the surgeon;
  • a spacious surgical site.


Clinical use of the Tritube in difficult airway scenarios is demonstrated from the University hospital, Rigshospitalet, in Copenhagen. Find video below:

Small Lumen Ventilation

Small Lumen Ventilation

The unique and proprietary Expiratory Ventilation Assistance technology, also known as EVA, actively induces expiration. EVA shortens expiration time, increases the achievable minute volume and reduces the risk of air trapping.
