Sieved/ fenestrated tracheostomy tubes. Tracheostomy tubes with completely unblocked. cuff and tracheostomy tubes without cuff

How does it work?
A special feature of this speaking valve is the closed basic position of the silicone membrane
The membrane only opens briefly during inspiration and reacts to even very weak inhalation
Afterwards it automatically returns to the
tightly sealed basic position without exhalation
pressure (expiration pressure) being required
(an extremely short shutting time);
phonation therefore does not require any build up of expiration pressure
