4. Inner cannula
A swivel connector is integrated in the insert of
DURATWIX
®
tracheostomy tubes with inner
cannulas: The inner cannula is securely fixed in place in the outer cannula by just a slight turn
in clockwise direction (in inserted condition from the patient's point of view) and without exerting
much pressure.
The inner cannulas differ in colouring according to their respective lengths. The standard-length
inner cannulas are transparent, the inner cannulas of the short versions are tinted in different
colours. Inner cannulas with fenestration can be recognized by the turquoise connector.
The inner cannulas are, depending on specification, either equipped with a standard attachment
or permanently connected to particular adapters/connectors, or they can be connected to
detachable accessories such as for instance speaking valves.
The inner cannulas can easily be removed from the outer cannula, thus allowing the air supply
to be increased quickly if necessary (for instance in case of dyspnoea).
Inner cannulas must never be used without outer cannula but must always be affixed to the
outer cannula.
The DURATWIX
®
tracheostomy tube series was designed as a modular system, i.e. for every
tracheostomy tube delivered as standard with inner cannula you can later on order further fitting
inner cannulas.
DURATWIX
®
inner cannulas have a labelling that indicates their size.
Caution!
Inner cannulae with a white-coloured cannula tube are radiopaque and facilitate x-ray
visualisation and positional control. Inner cannulae with a transparent cannula tube, on
the other hand, cannot be depicted on an x-ray.
4.1 Speaking valves
Tracheostomy tubes with speaking valve (LINGO/PHON) are used after tracheotomy with a
complete or partially retained larynx and enable the user to speak.
Some DURATWIX
®
inner cannulas (REF 19841/REF 19842) have a speaking valve attached
to the inner cannula.
The
HUMIDOPHONE
®
speaking valve or the
COMBIPHON
®
speaking valve are also available.
These can be used by tracheotomised patients who for instance use a perforated tracheostomy
tube (with inner cannula) with 22 mm combi-adapter.
In tracheostomy tubes with silicone speaking valve, the speaking valve can be detached
from the inner cannula by pulling it off.
5. Decannulation plug
The decannulation plug is included in delivery of the tracheostomy tubes with speaking valve
and may only be used by tracheotomised patients who have retained their larynx. It may only be
inserted under supervision by a doctor/physician. It allows the tracheostomy tube to be sealed
and the air supply to be interrupted for a short time and helps the patient train to regain control
of breathing via mouth/nose.
CAUTION!
Contraindicated in laryngectomised patients and patients with chronic obstructive
pulmonary disease (COPD)! In such cases, the decannulation plug must not under any
circumstances be inserted!
The decannulation plug must never under any circumstances be used when the
tracheostomy tube is in sealed condition! The decannulation plug may only be used with
perforated outer cannula without inner cannula.
CAUTION!
A decannulation plug is enclosed with the tracheostomy tubes with speaking valve for
the purpose of preparing for possible decannulation following temporary tracheotomy.
The plug can be used to block the air supply via the tracheostomy tube for a short time
so that the patient can get used to breathing via mouth/nose again. Decannulation may
only be carried out under medical supervision. The plug may only be inserted upon
instruction by the doctor/physician. There is a risk of suffocation! Please also make sure
you observe the description of indications provided with the respective product variants/
specifications!
CAUTION!
Make sure to read all accompanying product information, instructions for use, indications
and contraindications. Discuss use of the product with your doctor/physician before first
use.
