13-12 Probes and Biopsy
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.
NOTE:
Observe the graph here carefully to immerse the transducer. Only soak parts of the
transducer below the strain relief.
Sterilization of a critical probe
For intra-operative transducers, they have to be thoroughly cleaned and sterilized after
completing each examination.
1. Wear a pair of gloves to prevent infection.
2. Clean the probe thoroughly in accordance with the cleaning procedure before sterilization.
3. Sterilize the probe by using an appropriate sterilant. MINDRAY recommended the
following solution to sterilize the probe. For how to use the sterilant, see the operator's
manual provided by the manufacturer. Prepare a sterilant by using sterile water when
necessary.
Refer to the instructions provided by the chemical manufacturer concerning
concentration of the sterilization solution, method of sterilization and dilution and
cautions during use.
Do not soak the transducer connector or the cable near it into water or any solution.
Follow local regulations when selecting and using the sterilization solution.
4. Immerse the probe head partially in the sterilant 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 sterile distilled water (about 2
gallons) at room temperature for about 30s to remove the residual disinfectant. Repeat
the operation twice. Or, follow the rinsing method recommended by the manufacturer of
the sterilant to rinse the probe.
6. Dry the probe by wiping with a piece of sterile 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
sterilizing process before the next use.
