5.2
Treatment of contaminated parts in the ultrasonic transducer, vessels
and accessories pertaining to the medical
fi
eld
When working with ultrasonic homogenisers, the sonicating parts, vessels and other accessories
(e.g. stands, mounting tools) could become contaminated with microorganisms or toxicological
agents and lead e.g. to cross-infections. Disinfection and/or cleaning is required.
In the event of incorrect or irregular disinfection and cleaning, contamination is possible, especially
at the connecting points (e.g. between titanium plate and standard horn) and at the sound-emitting
surfaces (see chapter 5.1 , Wear).
Therefore, the sonicating parts (such as the standard or booster horn, micro tips or tapered tips,
and titanium plates), vessels and accessories should be disinfected and cleaned after every use,
and dismounted for this purpose if necessary.
In the event of toxic contamination, the applicable regulations and provisions of BGR 250/TRBA
250 are especially to be observed.
The disinfection and cleaning should be performed regularly by the operator, if applicable in
accordance with the hygiene plan and using a VAH-certi
fi
ed or other effective surface disinfectant.
Note:
Additional information and provisions locally applicable at the user's/operator's site must be
observed.
5.3
Warehousing / storage
During extended periods without use, the homogeniser should be stored in a cool, dry place.
The ultrasonic transducer should be covered in order to protect the electronics from outside
contamination.
