Mechanical procedure
The first part of our reprocessing of KaVo instruments series was about general notes and preparatory steps for the reprocessing procedure. In this blog post we want to tell you the steps of the mechanical reprocessing procedure.
1. Pre-Cleaning
Brush off any residual cement, composite and blood under running tap water.
Accessories required:
- Tap water 30° C ± 5°C
- Medium-hard toothbrush
2. Cleaning and disinfection (external and internal)
KaVo recommends washer disinfectors in accordance with EN ISO 15883-1 that are operated with alkaline cleaning agents that have a pH value of max. 10. The validations were conducted with a Miele thermal disinfector using the VARIO-TD program, the cleaning agent "neodisher mediclean", the neutralisation agent "neodisher Z" and the rinse agent "neodisher mielclear".
- In order to ensure residual liquids do not damage the KaVo medical device, the interior and the exterior must be dried.
- Remove any residual liquids from the interior and exterior of the medical device using KaVo DRYspray.
- Oil the handpiece immediately after drying.
3. Lubrication
KaVo QUATTROcare PLUS 2124 A:
Care device for perfect and efficient care.
- Reprocess the medical product after every application, i.e. after every cleaning, disinfection and prior to every sterilisation
- Reprocess the head and base separately for instruments with changeable heads
- Optimum care, thanks to automatic, outlet-specific, metered dosing
- Integrated chuck-care program
- Compressed-air blasting of transmission system and spray channels, using purging function
- Basic device, complete with four treatment couplings
(1 x MULTIflex / 3 x INTRAmatic)
Mechanical chuck servicing:
KaVo recommends cleaning and servicing the chucking system once every week.
- Close the front door and press the chuck service button for at least three seconds until the spray canister control LED flashes three times consecutively. The device is in chuck service mode
- Take the chuck service coupling out and attach it to coupling service point 4 (on the far right)
- Position the chuck adapter on the MULTIflex coupling of the QUATTROcare PLUS
- Press the instrument, with the chuck to be serviced leading, against the tip of the chuck service coupling
- Position the tip of the spray nipple in the opening of the chuck
- Press the button of chuck servicing
4. Packaging
Oil residues must be removed from the instruments prior to packaging.
- The sterilization bag must be large enough for the instrument so that the packaging is not stretched
- Seal the medical device separately in a sterile pack
- Check the sealed seam of the packaging
5. Sterilisation
KaVo products bearing the sterilisation symbol can be sterilised in steam sterilisers (autoclaves) according to EN 13060/ISO 17665-1 and have a maximum temperature stability of up to 138°C.
Sterilisation parameters:
Steam steriliser with triple pre-vacuum: At least 3 minutes at 134°C - 1°C / + 4°C (observe the application area of the steam steriliser and the KaVo instructions for use)
- Remove contra-angle handpieces and turbines immediately after the completion of the sterilisation cycle from the steam steriliser
- Reprocessed medical devices must be stored in a dry, dark, cool room, protected from germs and dust, as far as possible
6. Documentation
The process is released in written from on the following basis:
- The correctness of the process sequence must be tested.
Sterilisation:
- The packaging must be subjected to a visual inspection
- It must be ensured that the sterile goods are correctly marked
- Process indicators must exhibit a complete colour change
- The correct batch documentation is a prerequisite for the release
- The release of the sterile goods must be documented
Putting the products back into clinical use
Directly prior to providing treatment, attach instruments and turbines onto the motor or MULTIflex coupling. Activate handpiece and let it run for a few seconds. Wipe off any escaping lubrication oil.
