• Repeated sterilization may degrade the safety and performance of the
needle-guided bracket. Before use, please check whether the needle-
guided bracket has defects such as deformation and rusting. If such
defects exist, the bracket has reached the end of its service life. In this
case, stop using it and contact the Mindray service department.
• It is recommended to use immersion sterilization for plastic needle-guided
brackets and high-pressure steam sterilization for metal needle-guided
brackets.
• For detailed operations about the cleaning solvent, sterilant and high-
temperature steam sterilizer, see the respective operator’s manuals
provided by the manufacturer.
NOTE:
Disposable components are packaged sterile and are single-use only. Do not use if integrity of
packaging is violated or if expiration date has passed. Please use the disposable components
compliant with the relevant local regulations.
Cleaning
Perform the following procedure:
1.
Wear a pair of gloves to prevent infection.
2. After use, immerse the needle-guided bracket in distilled water immediately to prevent dirt
from drying. Wipe the entire surface of the needle-guided bracket by using a piece of
disposable lint-free soft cloth to remove coarse dirt.
3. Prepare a cleaning solvent (enzymatic or neutral pH detergent, e.g., liquinox, MetriZyme) by
using distilled or softened water in accordance with the operator’s manual provided by the
manufacturer.
4. Detach all the detachable parts of the needle-guided bracket and immerse the needle-guided
bracket and all its parts fully in the cleaning solvent for at least 1 minute or a period specified
by the manufacturer.
5. Immerse the needle-guided bracket and all its parts fully in the cleaning solvent. Wipe and
wash the surface and connecting parts of the needle-guided bracket gently by using a soft
brush until no dirt is visible. Place the needle-guided bracket inside an ultrasonic cleaner and
perform ultrasonic cleaning for 3–5 minutes.
6. Rinse the needle-guided bracket thoroughly by using a large amount of distilled or softened
water (about 2 gallons) at room temperature for about 30 s to remove the residual dirt and
cleaning solvent. Repeat the operation twice.
7. Wipe away the water on the needle-guided bracket by using a piece of disposable lint-free soft
cloth.
8. Inspect the needle-guided bracket. If visible dirt still exists, repeat the preceding steps to wash
the bracket until it is all clean.
Sterilization with a sterilant
Perform the following procedure:
1.
Wear a pair of gloves to prevent infection.
2. Clean thoroughly in accordance with the cleaning procedure before sterilization.
