Disinfection cabinet (high temperature and high pressure)
Scan tip sterilization for intraoral scanners under a high temperature and high pressure:
Please follow the instructions given below to ensure normal functionality of the intraoral scanner.
Cleaning steps:
1. Disconnect the power of the scanner, and pull the scanner tip off the scanner body.
2. Pre-clean the scanner tip with distilled water for 3 minutes to remove stains like the saliva or blood.
3. Brush the inside and the outside of the tip with enzyme surfactant for 3 minutes. Repeat the step for at least 2 times.
- When cleaning the inside of the tip, insert the sponge brush into the tip from both the front and rear ends, and move the brush lightly in tiny circles.
- When cleaning the outside of the tip, brush the surface back and forth lightly.
4. Rinse the tip thoroughly with distilled water for at least 3 minutes.
If there is any stain or fingerprint on the lens, repeat step 3 and 4.
Caution
Rinse the tip with distilled water every time and discard the used water. Do not reuse the water for rinsing or any other purpose.
6. Dry the scanner tip with a soft lint-free cloth, and put it in a well-ventilated place to ensure it’s totally dry, or put it in a dryer for 10 minutes.
7. Inspect the lens of the tip to make sure it is clean and free of damage.
Note：Before subjecting the scanner tip to high temperature and high pressure, make sure it is completely dry; otherwise, it may be damaged.
Reason: If we insert the entire tip into the liquid, immersing it, as written in the guide, but the result is an oxidation of the contacts on the scanner because the disinfectant liquid remains inside the TIP even if autoclaved, the bag keeps all the humidity inside and the result is that the contacts on the scanner then oxidize because they are moistened.
High temperature autoclave sterilization steps
1. Fill the scanner tip with medical gauze and seal it in the autoclave bag.
2. Put the wrapped scanner tip into a sterilizer for 30 minutes at 121°C under a relative pressure of 102.9kPa (or 4 minutes at 134°C under a relative pressure of 205.8kPa), and then dry it for 30 minutes.
Caution
After drying, cool the scanner tip to room temperature to avoid a scald.
3. Inspect the lens of the tip to make sure it is clean and free of damage.
4. If immediate use of the scanner tip is required, reconnect it; if not, store it with other dental instruments, and make sure it is totally dry.
Notes:
1. Daily-use tissues are not recommended due to residue left behind is hard to clean.
2. After cleaning, wipe the scan tip. Optic must be clean and dry.
3. Do not mix high-level disinfection and high-temperature sterilization in the same cleaning process. Then gently clean the scanning head to avoid residue of disinfectant and make sure the optic is clean.
