thermoplastics and silicone.
Lung emphysema, asthma and other pulmonary
diseases, which affect lung capacity, are contraindica-
tions for breath-controlled automatic speech valves.
Patients suffering from such diseases should only use
the Provox
®
by their physician that the benefits of the device clearly
outweigh the risk of its use.
The stoma size and the condition of the peristomal
skin may be factors contraindicating the use of the de-
vice and its required accessories. A stoma, which is too
small can limit the inhaled airflow and thereby lead to
too low a tidal volume. Hypersensitive skin may make
it impossible to attach the valve properly.
Warnings
Always assemble the device (HME cassette and valve
unit) before use. Using not properly assembled or single
device components may increase the risk of aspiration
of these components or device fragments, e.g. of lose
magnets in the case of a speech valve unit defect. Us-
ing the Provox
the valve unit may lead to aspiration of the cassette
or parts of it.
If the connection between the speech valve
unit and HME cassette becomes loose during use
or removal of the device, the HME cassette must be
removed from the tracheostoma only by removing the
complete Adhesive base plate from the skin. No other
manipulation must be done in such situation, in order
not to increase any risk of aspiration.
Excessive coughing-up of mucus may suddenly
block or nearly block your airway. Make sure you
always have the possibility to remove the device quickly
from your tracheostoma if needed.

the physiologically needed HME features, damages the
valve due to direct mucus contact and increases risks for
the user, including the risk of incidental loss of small
device parts and the risk of aspiration.
Do NOT reuse the foam, e.g. by washing out.
Doing so eliminates the calcium chloride needed for a
sufficient humidity exchange and can increase the risk
of infection.
Do NOT wear the Provox
