Cleaning / disinfection and sterilisation
Basics
Efficient cleaning / disinfection is an essential requirement for effective sterilisation of the handle.
Within the scope of responsibility for the sterility of the products it should be noted that only sufficiently
validated equipment and product specific processes are used for cleaning / disinfection and that the vali-
dated parameters are complied with in every cycle.
In addition, the hospital / clinic hygiene regulations must be observed.
Cleaning / disinfection
Cleaning and disinfection must be carried out immediately after use.
A mechanised process (disinfector) should be used for cleaning / disinfection. The efficiency of the proc-
ess used must be recognised and validated in principle (e.g. listed under disinfectants and disinfection
procedures tested and recognised by Robert-Koch-Institute / DGHM).
When using other procedures (e.g. a manual procedure), proof and process efficiency in principle must
be provided within the scope of validation.
Proof in principle of the suitability of the handles for efficient cleaning / disinfection was provided using a
cyclic cleaning system (Netsch-Bellmed T-600-IUDT/AN, programme 2 for small parts; code B).
It is not allowed to use agents / disinfectants, which contain the following substances, as these may
cause changes in the material:
- High-concentration organic and inorganic acids
- Chlorinated hydrocarbons
- 2-ethoxyethanol
When cleaning / disinfecting, the following procedures must be followed:
Process Time (sec.)
Zone 1 Pre-rinse, external, cold, 10 – 15°C 45
Washing, acidic, external 35°C 120
Draining time 10
Re-rinse, external approx. 80°C *10
Draining time *15
Re-rinse, external approx. 80°C *15
Draining time 15
Zone 2 Washing, alkaline, external, 93°C 135
Draining time 10
Re-rinse, external, acidic, 90°C 10
Draining time 15
Re-rinse, external 90°C 15
Draining time 15
Zone 3 Drying, external 100 – 120°C 200
Zone 4 Drying, external 100 – 120°C 200
Door open / close & transport 60
(sluice discharge)
Cycle time overall ca. 290
≈5 minutes
* When occupying the disinfection zone (washing zone 2), the re-rinse and draining times will depend on
the respective objects being washed therein!
