2. Clean the probe thoroughly in accordance with the cleaning procedure before disinfection.
3. Disinfect the probe by using an appropriate low-level disinfectant. Follow the disinfection
agent manufacturer’s instructions for preparation and use of the disinfectant.
4. If you use a wet wipe for disinfection, wipe all the surface of the probe according to the
wiping duration specified in the operator's manual provided by the manufacturer. If you
use a disinfectant spray, spray the disinfectant directly on the surface of the probe or
spray the disinfectant on a piece of disposable lint-free soft cloth and wipe the probe
according to the wiping duration in the operator's manual provided by the manufacturer.
5. Wipe away the residual disinfectant on the probe by using a piece of lint-free soft cloth
soaked with distilled water. Wipe three times. Or rinse the probe thoroughly by using a
large amount of distilled or softened water (about 2 gallons) at room temperature.
6. Dry the probe by wiping with a piece of disposable lint-free soft cloth. Do not dry the probe
by heating.
7. Check whether the probe has defects such as peeling, rifts, bumps, cracks, or liquid spill.
If such defects exist, the probe has reached the end of its service life. In this case, stop
using it and contact the Mindray service department.
8. Store the probe in a cool, clean and dry environment. And repeat the cleaning and
disinfection process before the next use.
Observe the graph here carefully to perform disinfection. Do not spray the strain
relief on the connector end or the connector.
High-level disinfection of a semi-critical probe
1. Wear a pair of gloves to prevent infection.
2. Clean the probe thoroughly in accordance with the cleaning procedure before disinfection.
3. Disinfect the probe by using an appropriate high-level disinfectant. For how to use a high-
level disinfectant, see the operator's manual provided by the manufacturer. Prepare a
disinfectant by using sterile distilled or softened water when necessary.
4. Immerse the probe head partially in the disinfectant and shake the probe appropriately to
remove any bubbles on the probe surface. For details about the probe immersion
duration, see the operator's manual provided by the manufacturer.
5. Rinse the probe thoroughly by using a large amount of distilled or softened water (about
2 gallons) at room temperature for about 30s to remove the residual disinfectant. Repeat
the operation twice.
