7.4 Ultrasound bath (optional)
All products must be opened, dismantled and any cavities rinsed through.
Place products in the screen basket in such a way that overlaps and contact between products are
avoided. Add cleaning agent to the water and adjust the temperature of the solution in line with the
cleaning agent manufacturer's instructions.
The cleaning in the ultrasound bath should be at 35-40 kHz, 5 minutes at least.
Subsequently rinse products including all cavities before cleaning and disinfection.
Medicine products which are possessing a bad ultrasound transmission, e.g. soft material are not
usable for the ultrasound bath.
7.5 Manual cleaning
7.6 Mechanical cleaning
On the basis of international standards (EN ISO 15883) and national directives, only validated
machine cleaning and disinfection methods may be used. For the mechanical cleaning we
recommend a standard program.
Only completely deminieralized water should be used for cleaning, neutralisation and rinsing, in
accordance with the „Guidance Complied by the DGKH (Germany Society for Hospital Hygiene),
DGSV (German Society for Sterile Supply) and AKI (Working Group on Instrument Reprocessing) for
the Validation and Routine Monitoring of Automated Cleaning and Thermal Disinfection Processes for
Medical Devices as well as Advice on Selecting Washer-
Disinfectors“ (which refers to DIN EN ISO
15883-1 Point 6.4.2)
Flexible (complex) products with invisible surfaces have to be pre-cleaned manually before
mechanical cleaning.
We recommend for all push shafts, -and pipe shafts instruments and instruments whose surfaces are
on top of each others during the cleaning (f.e. bone forceps and gouge forceps) a manually pre-
cleaning for an optimal cleaning result without residues
To validate cleaning in an ultrasonic bath, the test items were ultrasonically treated in
Neodisher Mediclean forte 0,5 % for 5 minutes.
Since mechanical processes can be standardizied, reproduced and therefore validated,
mechanical cleaning/disinfection should be preferred to manual processes.
Manual cleaning and disinfection process ist not validated and therefore needs to be
validated additionally by the end user.
