Operating the transvaginal probe
The transvaginal probe is an endocavity probe. For safe operation, please refer to “Care and maintenance” for correct
cleaning and disinfection.
The temperature at the tip of the probe is displayed on the monitoring screen. Temperatures above 43ºC are not al-
lowed. This also depends on the patient’s body temperature. If the temperature of probe tip exceeds 43º C, the probe
stops working immediately to protect the patient.
The transvaginal probe must be used with an FDA-approved condom or probe sheath. See the following instructions
for how to cover the probe with the condom:
CAUTION:
Some patients may have allergic reactions to natural rubber or medical devices that contain rubber. The
FDA suggests that the user ascertain these reactions in the patient and be prepared to treat these prior
to scanning.
Only water-soluble solutions or gel may be used. Petroleum- or mineral-oil-based materials may harm
the sheath.
When the transvaginal probe is activated outside the patient’s body, its acoustic output level should be
decreased to avoid any harmful interference with other equipment.
Operation procedure:
Put on medically sterile gloves. Take the condom out of its packaging. Unroll the condom. Put a little ultrasound gel into
the condom. Take the condom in one hand and put the probe head into the condom. Secure the condom on the end of
the probe handle. Confirm the integrity of the condom, and repeat the above steps for the condom if any damage is
found on it.

Cleaning and disinfecting TV and TR probes
We strongly recommend wearing gloves when cleaning and disinfecting endocavitary probes.
Before and after each exam, please clean the probe handle and disinfect the transvaginal and transrectal probes using
a liquid chemical germicide.
If the probe is contaminated with bodily fluids, you must disinfect the probe after cleaning. Regard all exami-
nation residues as potentially infectious and dispose of these accordingly.
CAUTION:
Since the probe is not waterproof, it must be disconnected from the system before cleaning or disinfec-
tion.
Before and after each exam, please clean the probe handle and disinfect the transvaginal and transrectal
probes using a liquid chemical germicide.
Cleaning
You can clean the transvaginal and transrectal probes with a soft cloth and remove all traces of coupling gel, then
rinse the probes under running water. Then wash the probe with mild soap in lukewarm water. Rub the probe as
needed and use a soft cloth to remove all visible residues from the surface of the transvaginal probe. Rinse the
probe with enough clean potable water to remove all visible soap residues, and let the probe air dry.
