FreeHands HME
The device is NOT MRI-compatible and must
NOT be worn during radiotherapy or x-ray.
Precautions
Handle the device with care.
Use only the recommended cleaning solutions/tab-
lets for cleaning and care. We recommend commercially
available denture cleaning tablets.
Never use oil-based detergents, boil or sterilize the
device, since this might destroy the valve.
For adjustment of the valve, i.e. the exchanging the
speech valve membrane or adjusting the cough valve
magnet, only use the Adjustment Kit (plastic forceps
and safety screwdriver) provided with the Provox
FreeHands HME
Adverse.Events
The patient should watch for any change in the stoma
tissue, the tissue around the voice prosthesis, increasing
difficulties in breathing, or similar symptoms. If any
of these symptoms or any other difficulties possibly
related to the use of the device occur, a clinician should
be consulted.
Some patients may experience a reaction to the
Provox
Adhesive. Discontinue use of Adhesive until
®
the reaction resolves. The use of Provox
(hydrocolloid) Adhesive, skin protection with Skin-
Prep
or wearing a LaryTube may reduce the risk of
™
such reactions.
Device.Lifetime.Expectation.
The HME should be replaced at least every 24 hours
or as often as needed when the HME is blocked by
mucous, etc.
Device ageing and long-term usage of the reus-
able valve unit may lead to improper valve function.
Symptoms for a worn-out Speech Valve Membrane can
include delayed closing and / or opening, air leaks and
increased closing sound. Symptoms for a defective valve
housing include mechanical defects and / or changes in
the cough-relief valve function.
Regular conditions provided, the Speech Valve
Membranes withstands a minimum of 6 months use,
and the valve housing of 12 months use. Proper han-
dling, cleaning and storage according to the instructions
further below are important factors to maintain the
device function.
Speech Valve Membranes for replacement are sepa-
rately available (REF 7713, 7714 and 7715).
