rator and tracheostomy tube to facilitate insertion.
Insert the obturator and the tube into the trachea through the
tracheostoma. Then remove the obturator immediately, insert an
inner cannula and block the cuff (as per chapter 8.3, item 4).
If necessary, a size 07 – 10 white obturator can also be used in
combination with a Seldinger wire Ø 1.27 ± 0.04 mm. The recan-
nulation tube is suitable for all sizes.
9. Handling
9.1 Changing the Inner Cannulas
If viscous secretion collects in the inner cannula and cannot be
suctioned, thus impeding airflow, replace the inner cannula with
a new or cleaned inner cannula.
To remove the inner cannula, turn the 15 mm connector of the
inner cannula anticlockwise (C).
Once a new inner cannula has been inserted into the outer can-
nula, turn the 15 mm connector clockwise until it locks into place,
i.e. the markings are aligned with each other (C).
Inner cannulas with grooved low profile connectors function in
the same way.
9.2 Fenestrated Tracheostomy Tubes
Unfenestrated inner cannulas have white 15 mm connectors and
are used, for example, during mechanical ventilation.
To allow the patient to speak, insert a fenestrated inner cannula
(blue 15 mm connector or blue grooved low profile connector)
in the fenestrated outer cannula and unblock the cuff. Insert a
speaking valve on the 15 mm connector of the inner cannula.
Follow the instructions for use of the respective speaking valve.
The inner cannula REF 401 (not supplied) has an integrated
speaking valve.The valve allows air to enter the trachea through
the tube on inspiration; on expiration, the valve closes and the
air flows alongside the tube, as well as through the fenestration,
through the larynx into the upper respiratory tract, which allows
vocalisation.
If there is an urge to cough or possible breathing difficulties, the
REF 401 valve leaflets can be folded back and the patient can
breathe unimpeded.
CAUTION: Speaking valves must only be used in patients who
are awake and can breathe spontaneously. When a speaking
