• The user must check the
Laryvox
®
Hands-Free Valve
for completeness,
absence of damage and proper functioning of the product each time before
inserting it again ➊!
•
To prevent injury, it is advisable to first connect the speaking valve to the
tracheostomy tube and then to insert the tracheostomy tube with attached
speaking valve into the tracheostoma. Otherwise, excessive pressure could
be exerted on the mucous membranes via the cannula tube when the
speaking valve is snapped into place.
• You should adjust the speaking valve before attaching it and set the opening
thickness of the valve disc by turning it ➋. The further the valve is opened,
the more air can be inhaled. However, the exhalation pressure necessary to
close the valve while speaking is then also greater. For normal respiration and
normal physical activity, it is therefore recommended that you set the valve
such that sufficient air can flow in, but without opening the valve completely. It
is recommended that you open the valve to the maximum only for strenuous
physical and sporting activities, in which your breathing becomes deeper.
• After you have adjusted the valve disc to the desired opening thickness,
insert the speaking valve together with the insertion ring, which can be seen
on the small circumferential retaining bead, into the 22 mm adapter of the
cannula ➌.
• If special base plates are used for adhesion (e.g. LARYVOX
®
Tape), first
fasten the base plate according to the instructions.
• Then carefully insert the
LARYVOX
®
Hands-Free Valve
into the retaining
ring of the ➍ base plate, so that a secure connection is established.
• If you are using a
LARYVOX
®
Hands-Free Valve
for TrachiNaze
®
and
LARYVOX
®
Hands-Free Valve
Combi HME, now insert the additional filter
➎ / ➏.
• The retaining bead ensures that the speaking valve will be seated stably.
• The strap (
LARYVOX
®
Hands-Free Valve
Low Resistance version) serves
as a spacer to prevent restriction of breathing by clothing or the like. It is not
suitable as a handle for positioning the speaking valve.
IX. Service Life
• The service life of the
LARYVOX
®
Hands-Free Valve
is influenced by many
factors. Thus, the composition of secretions, conscientious cleaning and
other aspects can be of decisive significance.
• The
LARYVOX
®
Hands-Free Valve
has an expected life of twelve month
when carefully treated. After that, the product must be replaced.
• A speaking valve showing damage of any kind, even if only minor, must be
replaced immediately.
• Speaking valves that are presently not being used should be stored in a dry
environment in a clean plastic container, protected from dust, sunlight and/
or heat.
