9. CLEANING AND DISINFECTION
- Cleaning is the first necessary step for any disinfection process. Rubbing with detergents and
surfactants and rinsing with water removes allows removing a considerable number of microorganisms.
If a surface is not cleaned first, the disinfection process cannot be successful.
The x-ray unit can be a source of cross-contamination between patients.
For this reason it should be disinfected on the outside every day after use.
If digital x-ray sensors are used, make sure that they are always used with disposable hygienic covers.
Use soft disposable paper towels to disinfect the x-ray unit. Do not use harsh products or soak in liquids.
It is recommended to use the specific medium-level disinfectant, STER 1 PLUS (CEFLA S.C.), which is compatible
with painted surfaces, plastic parts and unpainted metal surfaces. Alternatively, it is recommended to use products
that contain:
- 96% ethanol.
Concentration: maximum 30 g for every 100 g of disinfectant.
- Propanol.
Concentration: maximum 20 g for every 100 g of disinfectant.
- Combination of ethanol and propanol.
Concentration: the combination of the two should be maximum 40 g per 100 g of disinfectant.
Compatibility tests between plastics and the following products have been carried out with no negative
consequences:
- Incidin Spezial (Henkel Ecolab);
- Omnizid (Omnident);
- Plastisept (Alpro) (not tuberculocide as not an alcohol-based disinfectant);
- RelyOn Virkosept (DuPont);
- Green & Clean SK (Metasys) (not tuberculocide as not an alcohol-based disinfectant).
- Do not use products containing isopropyl alcohol (2-propanol, iso-propanol).
- Do not use products containing sodium hypochlorite (bleach).
- Do not use products containing phenols.
- Do not spray the selected products directly on the surfaces.
- Never combine products with each other or with liquids other than the products listed above.
- All products must be used as directed by the manufacturer.
- The recommended products have been tested: they are technically compatible with the device
materials.
- Damages to surfaces and materials due to the use of different products cannot be excluded even if they
are not included in the exceptions mentioned above.
Cleaning and disinfecting instructions.
Clean and disinfect with disposable soft, non-abrasive paper (avoid using recycled paper) or sterile gauze.
Do not use sponge cloths or, in any case, any material that can be reused.
- Turn off the device prior to cleaning and disinfecting the external parts.
- Never lubricate the pivot point of the x-ray head as proper operation of the locking system may be
compromised.
- All material used to clean and disinfect must be thrown away upon completing the procedure.
