8.1
Cleaning and disinfection
8.1.1
General
Performed by hygiene specialist staff
Cleaning and disinfection of the surgical lights may only be performed by a hygiene
specialist or a person instructed by the hygiene specialist.
Only use recommended cleaning agents
and disinfectants
For cleaning and disinfection you should only use agents and chemicals tested by and
approved by Trumpf Medical with regard to their material compatibility in
accordance with Chapter 8.1.3, page 41. If an agent is not included on the list it
should not be used as otherwise functional components could be changed or
damaged.
Basic cleaning before disinfection
Thorough cleaning of visible dirt, e.g. by body fluids, must be performed before the
actual disinfection.
• Cleaning may not involve sharp, pointed or abrasive objects or scouring agents or
agents containing material with abrasive effects, as this might damage the
surfaces.
Damaged surfaces can be penetrated and destroyed by chemical
substances.
• Only soft brushes and mild detergents or cleaning disinfectants may be used to
remove strong and persistent dirt. Disinfection may start after no more visible
dirt can be found.
Only use wipe-over disinfection
Use the wipe-over method only for disinfection. Disinfection by UV irradiation or
steaming is not permissible.
Warranty claim
Failure to comply with cleaning or disinfection requirements will render
any warranty claim void. No warranty is accepted for damage which is
due to the use of unsuitable cleaning agents or disinfectants.
---------------------------------------------------------------------------------------
The warranty applies only to undamaged surfaces!
8.1.2
Wipe-over disinfection
Wipe-over disinfection is used to disinfect the light head and the support arm system.
The light head may only be cleaned and disinfected when it is cold.
Only wipe with a damp cloth
For cleaning and disinfection, wipe the device components only with a damp but not
wet cloth. Wiping should apply only a thin film of liquid and after wiping only a thin
coherent film of moisture should remain. From the microbiological point of view, this
moisture film is entirely sufficient. Liquid should not pool on the surface.
Avoid the build-up of a coating
If too much liquid is applied to the surface during disinfection, residues will be left on
the product. To prevent the build-up of a coating of disinfectant residues, regular
cleaning with a mild all-purpose cleaner is necessary.
Cleaning to be carried out at least monthly
The regularity of cleaning will depend on the frequency of disinfection but must be at
least once a month.
Only clean the surgical light with a damp but not wet cloth.
Cleaning procedure
1. All poles of the operating lamp must be disconnected from the power supply
and secured against switching on.
2. Allow the light head to cool down. Only clean or disinfect the light head when it
is cold.
