3-2 Examination

Clean and disinfect transducer. See “Cleaning and disinfecting” on page 4-1.
Contact FUJIFILM SonoSite or your local representative to report any damage or discrepancies.See
“Technical Support” on page 1-3.
Precautions
Techniques for introducing the TEExi transducer into the patient are beyond the scope of the user guide.
There are numerous medical texts and articles that thoroughly address this topic. Observe the following
precautionary measures when conducting an exam.

Maintaining an unobstructed airway is a prime consideration for all patients.

Prolonged pressure on the esophagus by the tip of the transducer may lead to a pressure necrosis
condition. Thus, in operating room monitoring applications, the tip should be removed from the esophagus
wall when not scanning, by releasing it in the neutral position. If continuous monitoring is required, the
transducer tip should be repositioned often.

Long term exposure to ultrasound should be minimized. Although there have never been any bioeffects
demonstrated at the acoustic output levels of the TEExi transducer, it is prudent to minimize patient
exposure to ultrasound according to the principle of ALARA (As Low As Reasonably Achievable). Please
see the ultrasound system user guide.

In consideration of the above two points, you should freeze the image, which turns off the power to the
transducer, and allow the endoscope deflection controls to be disengaged whenever active scanning is
not desired.

Proper patient preparation is essential for successful examinations. This includes restrictions on food and
liquid intake as well as a thorough explanation of the examination procedure and other instructions as the
particular situation warrants.

The use of a bite guard during all TEExi examinations is mandatory to protect the transducer from possible
damage.

The use of protective gloves during the examination is encouraged. Please see the U.S. Food and Drug
Administration’s Medical Alert on Latex Products (FDA 1991).
WARNINGS To avoid injury to the patient:

FUJIFILM SonoSite recommends performing the above procedures prior to
each exam.

Do not use the transducer if any metallic protrusions, holes, rough spots, cracks,
or dents are found.

If during the deflection test a sharp “U-turn” of the transducer tip is observed
(the transducer tip angle exceeds the maximum deflection angles), do not use
the transducer. Call FUJIFILM SonoSite or your local representative.

Some gels and sterilants can cause an allergic reaction in some individuals.
