The cleaning, disinfection and sterilization of optical ber is as follow.
Unless otherwise stated, they will be hereinafter referred to as “products”.
Warnings
The use of strong detergent and disinfectant (alkaline pH>9 or acid
pH <5) will reduce the life span of products. And in such cases, the
manufacturer takes no responsibility.
This device shall not be exposed to high temperature above 138℃.
Processing limit

6
The pro ducts have been designed for a large number of sterilization
cycles.
The materials used in manufacture were selected accordingly. However
with every renewed preparation for use, thermal and chemical stresses
will result in ageing of the products. The maximum number of
sterilizations for optical ber is 500 times.
6.1 Initial processing
6.1.1 Processing principles
It is only possible to carry out eective sterilization after the completion
of eective cleaning and disinfection. Please ensure that, as part of your
responsibility for the sterility of products during use, only suciently
validated equipment and product-specific procedures are used for
cleaning/disinfection and sterilization, and that the validated parameters
are adhered to during every cycle.
Please also observe the applicable legal requirements in your country as
well as the hygiene regulations of the hospital or clinic,especially with
regard to the additional requirements for the inactivation of prions.
6.1.2 Post-operative treatment
The post-operative treatment must be carried out immediately, no later
than 30 minutes after the completion of the operation. The steps are as
follows:
1. Remove the optical ber from the Curing light Device,and rinse away
the dirt on the surface of product with pure water (or distilled water/
deionized water);

7
2. Dry the product with a clean, soft cloth and place it in a clean tray.
Notes
a) The water used here must be pure water, distilled water or deionized
water.
6.2 Preparation before cleaning
Steps
Tools: tray, soft brush, clean and dry soft cloth Remove optical fiber
from main unit and put it into the clean tray.
Use a clean soft brush to carefully brush the optical ber until the dirt
on surface is not visible. Then use soft cloth to dry the optical ber and
put them into a clean tray. The cleaning agent can be pure water, distilled
water or deionized water.
6.3 Cleaning
The cleaning should be performed no later than 24 hours after the
operation.
The cleaning can be divided into automated cleaning and manual
cleaning. Automated cleaning is preferred if conditions permit.
6.3.1 Automated cleaning

It is recommended to use a washer-disinfector in accordance with EN
ISO15883. For the specific procedure, please refer to the automated
disinfection section in the next section “Disinfection”.
Notes
a) The cleaning agent does not have to be pure water. It can be distilled
water, deionized water or multi-enzyme. But please ensure that the
selected cleaning agent is compatible with the product.
b) In washing stage, the water temperature should not exceed 45 °C,
otherwise the protein will solidify and it would be dicult to remove.
c) After cleaning, the chemical residue should be less than 10mg / L.
6.4 Disinfection
Disinfection must be performed no later than 2 hours after the cleaning
phase.
Automated disinfection is preferred if conditions permit.
