5.3. Treatment of medical instruments
- The instruments may not be placed on the tank bottom. The basket avoids damages
at the instruments and at the tank bottom. Do not staple instruments, overloading
reduces the cleaning efficiency. Pliers and scissors must be opened completely or
detached, if necessary. Instruments must be completely covered with cleaning liquid,
air has to escape from cavities and hoses.
- When disinfecting and cleaning contaminated medical instruments in ultrasonic baths,
the hygienic safety is important after the treatment. In case of improper and irregular
disinfection and cleaning a micro-biological contamination is possible caused by
settlement of microorganism, especially at the tank rim or in the drain section. Cross
infection might be a result. Therefore, the tank and housing surfaces must be regularly
disinfected and cleaned.
According to the hygienic plan the user must carry out regular disinfection and
cleaning with a surface disinfecting agent certified by DGHM*, or another efficiently
classified agent.
