12-10 Probes and Biopsy
Contacts otherwise sterile tissue or blood: These transducers are considered critical and
include all intraoperative transducers. These transducers must be cleaned with an
appropriate cleaner after each use, followed by a sterilization process.
Cleaning
Please refer to the instructions in the manual and follow your hospital policy and procedures
for cleaning.
1. Wear a pair of gloves to prevent infection.
2. Disconnect the ultrasound probe from the ultrasound system. If the sheath is used, take off
the sheath and discard it.
3. Wipe away the ultrasound gel or other dirt on the surface of the probe by using a piece of
disposable lint-free soft cloth or tissue.
4. 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.
5. Immerse the ultrasound probe fully in the cleaning solvent for at least 1 minute or a period
specified by the manufacturer.
6. Wipe and wash the probe surface gently by using a piece of lint-free soft cloth or soft
sponge until no dirt is visible. When necessary, wash the locating groove of the needle-
guided bracket and other items by using disposable cotton swabs. Avoid using a brush to
wash the lens because it may damage the probe.
7. 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 dirt and cleaning solvent.
Repeat the operation twice.
8. Dry the probe by wiping with a piece of disposable lint-free soft cloth or tissue. Do not dry
the probe by heating.
9. Inspect the probe. If visible dirt still exists, repeat the preceding steps to wash the probe
until it is all clean.
10. 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.
Low-level disinfection of a non-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 low-level disinfectant. If you use a wet wipe
for disinfection, refer to the wiping method specified by the supplier and the wiping
duration specified in the operator's manual provided by the manufacturer. If you use a
disinfectant spray, spray the disinfectant on a piece of disposable lint-free soft cloth and
wipe the probe. For details about the wiping duration, see the operator's manual provided
by the manufacturer.
4. Wipe away the residual disinfectant on the probe by using a piece of lint-free soft cloth
