4.1 Sterilisable handle

For an additional charge, the KaWe examination light can be equipped
with the sterilisable handle sleeve 8. The removable handle sleeve
can be steam sterilised and must be cleaned, disinfected and sterilised
before the first and each subsequent use.
To be sterilised, the handle sleeve must be removed:
• To remove the sterilisable handle sleeve 8, press and hold down the
locking mechanism V and pull the handle sleeve off in a downward
motion.
• Put the handle sleeve 8 back on by pushing it back on with a twist-
ing motion until the locking mechanism V clicks securely.
During an examination, the handles often become unsterile.
Therefore, ensure that additional replacement handles are kept at
hand.
Cleaning/Disinfection and Sterilisation
Basics
Effective cleaning and disinfection are key requirements for effective
sterilisation of the handle. The responsibility for the sterility of these
products includes ensuring that only sufficiently-validated equipment
and product-specific processes are used for cleaning/disinfection and
that the validated parameters are complied with during every cycle. In
addition, the hospital / clinic hygiene regulations must be observed.
Note: The national board requirements (norms and directives) for
hygiene and disinfection must be followed.
Cleaning / disinfection
Cleaning and disinfection must take place immediately after use.
A mechanical sterilisation procedure should be used for cleaning /
disinfection. Only procedures with proven effectiveness may be used
(e.g. those listed under disinfectants and disinfection procedures that
are tested and recognised by Robert-Koch-Institute / DGHM) and they
must always have already been previously validated. When using other
procedures (such as manual cleaning), proof of the effectiveness of the
procedure must be given as part of the validation. The principle proof
of the suitability of the handles for efficient cleaning / disinfection was
carried out using a cyclic cleaning system (Netsch-Bellmed T-600-
IUDT/AN, programme 2 for small parts; code B).
Agents / disinfectants containing the following substances may not be
V
used as these may cause changes in the material:
• High-concentration organic and inorganic acids
• Chlorinated hydrocarbons
• 2-ethoxyethanol
When cleaning and disinfecting, the following procedures
must be followed:
