3.6
Manual cleaning/disinfection
►
Prior to manual disinfecting, allow water to drip off for a sufficient length of time to prevent dilution of the dis-
infecting solution.
►
After manual cleaning/disinfection, check visible surfaces visually for residues.
►
Repeat the cleaning/disinfection process if necessary.
3.6.1
Manual cleaning with immersion disinfection
D–W:
Drinking water
FD–W: Fully desalinated water (demineralized, microbiological, at least of drinking water quality)
RT:
Room temperature
*Recommended: BBraun Stabimed fresh
►
Note the information on appropriate cleaning brushes and disposable syringes, see Validated cleaning and dis-
infection procedure.
Phase I
►
Fully immerse the product in the cleaning/disinfectant for at least 15 min. Ensure that all accessible surfaces are
moistened.
►
Clean the product with a suitable cleaning brush in the solution until all discernible residues have been removed
from the surface.
►
If applicable, brush through non-visible surfaces with an appropriate cleaning brush for at least 1 min.
►
Mobilize non-rigid components, such as set screws, links, etc. during cleaning.
►
Thoroughly rinse through these components with the cleaning disinfectant solution (at least five times), using a
disposable syringe.
Phase II
►
Rinse/flush the product thoroughly (all accessible surfaces) under running water.
►
Mobilize non-rigid components, such as set screws, joints, etc. during rinsing.
►
Drain any remaining water fully.
Phase III
►
Fully immerse the product in the disinfectant solution.
►
Mobilize non-rigid components, such as set screws, joints, etc. during rinsing.
►
Rinse lumens at least 5 times at the beginning of the exposure time using an appropriate disposable syringe.
Ensure that all accessible surfaces are moistened.
Phase IV
►
Rinse/flush the product thoroughly (all accessible surfaces).
►
Mobilize non-rigid components, such as set screws, joints, etc. during final rinse.
►
Rinse lumens with an appropriate disposable syringe at least five times.
►
Drain any remaining water fully.
Phase V
►
Dry the product in the drying phase with suitable equipment (e.g. cloth, compressed air), see Validated cleaning
and disinfection procedure.
3.6.2

surfaces are immersed and acoustic shadows are avoided.
►
Clean the product with a suitable cleaning brush in the solution until all discernible residues have been removed
from the surface.
►
If applicable, brush through non-visible surfaces with an appropriate cleaning brush for at least 1 min.
►
Mobilize non-rigid components, such as set screws, links, etc. during cleaning.
►
Thoroughly rinse through these components with the cleaning disinfectant solution (at least five times), using a
disposable syringe.

►
Rinse lumens at least five times at the beginning of the exposure time with an appropriate disposable syringe.
Ensure that all accessible surfaces are moistened.
Phase IV
►
Rinse/flush the product thoroughly (all accessible surfaces) under running water.
►
Mobilize non-rigid components, such as set screws, joints, etc. during final rinse.
►
Rinse lumens with an appropriate disposable syringe at least five times.
►
Drain any remaining water fully.
Phase V
►
Dry the product in the drying phase with suitable equipment (e.g. cloth, compressed air), see Validated cleaning
and disinfection procedure.
3.7
Mechanical cleaning/disinfection
Note
The cleaning and disinfection device must be of tested and approved effectiveness (e.g. FDA approval or CE mark
according to DIN EN ISO 15883).
Note
The cleaning and disinfection device used for processing must be serviced and checked at regular intervals.
3.7.1
Mechanical alkaline cleaning and thermal disinfection
►
Process the implant in its system storage device.
►
Place the implants on a tray that is suitable for cleaning (avoiding rinsing blind spots and damage).
Machine type: single-chamber cleaning/disinfecting machine without ultrasound
D–W:
Drinking water
FD–W: Fully desalinated water (demineralized, microbiological, at least of drinking water quality)
*Recommended: BBraun Helimatic Cleaner alkaline
►
Check visible surfaces for residues after mechanical cleaning/disinfecting.
3.8
Mechanical cleaning/disinfection with manual pre-cleaning
Note
The cleaning and disinfection device must be of tested and approved effectiveness (e.g. FDA approval or CE mark
according to DIN EN ISO 15883).
Note
The cleaning and disinfection device used for processing must be serviced and checked at regular intervals.
