Information on care, cleaning and disinfection
All Riester ri-scope ®
instrument heads can be cleaned on the
outside with a moist cloth. Furthermore, the following disinfec-
tants can be used: Aldehydes (formaldehyde, glutaraldehyde,
aldehyde fission products) or tensides. All parts of instruments
with the exception of the swivel lens, magnifying glass and the
cover glass can also be disinfected with alcohols. When using
these substances it is absolutely essential to follow the instruc-
tions of the manufacturer. A soft and, as far as possible, lint-free
cloth or cotton bud can be used as an auxiliary aid for cleaning or
disinfection.
Attention
Never place the instrument heads in liquid. Take care that no
liquid enters inside the casing.
a) Sterilisation
According to the current school of thought (Test Centre for Me-
dical Devices in Tübingen), sterilisation is only prescribed in the
case of operative procedures.
b) Reusable ear specula
Although sterilisation is not necessary as described in a), it is
nevertheless possible. The reusable ear specula can be sterilised
at 134°C and 10 minutes retention time in a steam sterilizer.
