NOTE: 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.
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. Repeat the cleaning and disinfection process
before the next use.
