The reusable tip or small tip is the part that is inserted into the patient’s mouth during scanning. The tip is reusable for a limited number of times. The tip needs to be cleaned and sterilized between patients to avoid cross-contamination.
1. Reusable Tip & Small Tip
1.1.Cleaning and Disinfection
- Clean the tip immediately after use with soap water and a brush. We recommend using a mild dishwashing liquid. Make sure the mirror of the tip is completely clean and stain-free after cleaning. If the mirror appears stained or foggy, repeat the cleaning process and rinse thoroughly with water. Dry the mirror carefully with a paper towel.
1.2.Disinfection
- Disinfect the tip with Caviwipes according to the following conditions. Please refer to the Caviwipes instruction manual for proper use.
◼ Caviwipes: Disinfect for 3 minutes and dry for 5 minutes
◼ Caviwipes-1: Disinfect for 1 minute and dry for 5 minutes
◼ Caviwipes-2: Disinfect for 2 minutes and dry for 5 minutes
- The tip should be cleaned manually using a disinfecting solution. After cleaning and disinfecting, inspect the mirror inside the tip to ensure there aren’t any stains or smudges.
- Repeat the cleaning and disinfection process if necessary. Carefully dry the mirror using a paper towel.
1.3.Sterilization
Autoclave Sterilization
- Insert the tip into a paper sterilization pouch and seal it, making sure that it is airtight. Use either a self-adhesive or heat-sealed pouch.
-
Sterilize the wrapped tip in an autoclave with the following conditions:
[i600, i700, i700 wireless tip]
◼ Sterilize for 30 minutes at 121°C (249.8°F) at gravity type and dry for 15 minutes.
◼ Sterilize for 10 minutes at 135°C (275°F) at gravity type and dry for 30 minutes.
◼ Sterilize for 4 minutes at 134°C (273.2°F) at pre-vacuum type and dry for 20 minutes.
[i500 tip]
◼ Sterilize for 30 minutes at 121°C (249.8°F) at gravity type and dry for 15 minutes.
- Use an autoclave program that dries the wrapped tip before opening the autoclave.
- i600, i700, i700 wireless Scanner tips can be re-sterilized up to 150 times(i500 scanner tips can be re-sterilized up to 50 times) and thereafter must be disposed of as described in the disposal section.
- Autoclave times and temperatures may vary depending on the autoclave type and manufacturer. For this reason, it may not be able to meet the maximum number of times. Please refer to the user’s manual of the autoclave manufacturer you are using to determine whether the required conditions are met.
Cold Sterilization
- Disinfect the tip for 45 to 60 minutes with Wavicide-01. Please refer to the Wavicide-01 Solution instruction manual for proper use.
- Remove the tip from the used solution and rinse thoroughly after cleaning and sterilization.
- Use a sterilized and non-abrasive cloth to dry the mirror and the tip gently.
⚠️Caution
- The mirror found in the tip is a delicate optical component that should be handled with care to ensure optimal scan quality. Be careful not to scratch or smudge it as any damage or blemishes may affect the data acquired.
- Make sure to always wrap the tip before autoclaving. If you autoclave an exposed tip, it will cause stains on the mirror, which cannot be removed. Check the autoclave manual for more information.
- Tips that have been cleaned, disinfected, and sterilized must remain sterile until they are used on the patient.
- Medit is not responsible for any damage, such as distortion of the tip, that occurs during cleaning, disinfection, or sterilization operations that are not following the guidelines above.
1.4 Disposal
⚠️Caution
- The scanner tip must be sterilized before disposal. Sterilize the tip as described in the section “1.3.Sterilization”.
- Dispose of the scanner tip as you would any other clinical waste.
- Other components are designed to conform with the following directives:
RoHS, Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment. (2011/65/EU)
WEEE, Waste Electrical and Electronic Equipment Directive. (2012/19/EU)
2. Mirror
The presence of impurities or smudges on the tip mirror may lead to poor scan quality and an overall poor scanning experience.
In such situations, clean the mirror following the steps below:
① Disconnect the scanner tip from the handpiece.
② Pour alcohol on a clean cloth or cotton-tipped swab and wipe the mirror. Make sure to use alcohol that is free of impurities or it may stain the mirror. You can use either ethanol or propanol (ethyl-/propyl alcohol).
③ Wipe the mirror dry using a dry, lint-free cloth.
④ Make sure the mirror is free of dust and fibers. Repeat the cleaning process as necessary.
3. Handpiece
After treatment, clean and disinfect all other surfaces of the handpiece except for the scanner front (optical window) and end (air vent hole). Cleaning and disinfecting must be done with the device turned off. Use the device only after it is completely
dry.
The recommended cleaning and disinfecting solution is denatured alcohol (ethyl alcohol or ethanol) – typically 60 – 70% Alc/Vol.
The general cleaning and disinfecting procedures are as follows:
① Turn off the device using the power button.
② Unplug all the cables from the wireless hub.
③ Clean the optical window on the front end of the handpiece.
◼ The optical window must be gently wiped with a cotton or soft cloth moistened with alcohol.
◼ Do not clean the optical window by pouring alcohol or cleaning solution directly into the optical window, it may seep inside the handpiece and cause a malfunction.
◼ Do not wipe by hand or apply excessive force.
◼ Medit is not responsible for any damage or malfunction that occurs during cleaning that does not follow the guidelines above.
④ Put the cover on the front of the handpiece after cleaning the optical window.
⑤ Pour the disinfectant onto a soft, lint-free, and non-abrasive cloth.
⑥ Wipe the scanner surface with the cloth.
⑦ Dry the surface with a clean, dry, lint-free, and non-abrasive cloth.
⚠️Caution
- Do not clean the handpiece when the device is turned on as the fluid may enter the scanner and cause malfunction.
- Use the device after it is completely dry.
- Chemical cracks may appear if improper cleaning and disinfecting solutions are used during cleaning.
4. Other Components
- Pour the cleaning and disinfecting solution onto a soft, lint-free, and non-abrasive cloth.
- Wipe the component surface with the cloth.
- Dry the surface with a clean, dry, lint-free, and non-abrasive cloth.
⚠️Caution
- Chemical cracks may appear if improper cleaning and disinfecting solutions are used during cleaning.
