To manually disinfect the individual parts, place them in the ready-to-use
disinfectant solution (instrument disinfection agent). All of the parts must
be fully covered by the disinfectant, and they must be free from bubbles.
After the dwell time, the disinfectant must be completely rinsed off using
demineralized water. Afterwards, the parts must be dried thoroughly.
Once manual disinfection is complete, check the parts for visible residual
contamination. If necessary, repeat the manual cleaning and disinfection
process.
With regard to material compatibility, suitable cleaning agents and
disinfectants are instrument disinfection agents that use alcohol and
aldehydes as the active ingredient, such as gigasept
®
ff from Schülke &
Mayr. The efficacy of the disinfectant that is used must be proven.
Products based on the following are not suitable because they could
possibly damage materials:
- Highly alkaline solutions
- Petroleum or acetone
- Oxygen-releasing or chlorine-releasing compounds
- Halogen-releasing compounds
- Phenols and their derivatives
- Amines and their derivatives
- Strong organic acids
Products listed in the most current version of the DGHM list published by
the Deutsche Gesellschaft für Hygiene und Mikrobiologie (German
Society of Hygiene and Microbiology) (mhp-Verlag, Wiesbaden) are
recommended for users in the Federal Republic of Germany.
11.5 Cleaning and disinfection of device surfaces
Use ready-to-use disinfectant solution to disinfect the surfaces of the
device. Completely wipe down the surfaces using the wiping cloth. The
wiping cloth should only be moist.
When using wipe disinfection, ensure that no liquid enters the device. Liquid ingress
can impair the operation of the device and thereby pose a risk to the patient.
