Introduction
It is important that you test the TEEx, TEExi,or TEExp transducer for punctures and tears in the waterproof
coating before every procedure. If any damage, irregularity, substandard functioning, or unsafe condition is
observed or suspected, do not use the transducer. Call FUJIFILM SonoSite or your local representative.

Testing for bite holes 3
Nederlands
The endoscope shaft has no electrically conducting surfaces and is covered with a layer of material that
permits neither fluids nor electricity to pass through it. Electrical safety is maintained for the transducer by
keeping this material intact. Punctures in this material, such as those resulting from bites or improper
handling, can result in fluids entering the endoscopic shaft and the patient being exposed to electrical
current. Each transducer is tested for electrical isolation and leakage current before it is shipped to a
customer.
Testing for bite holes
FUJIFILM SonoSite recommends testing the endoscopic shaft and the transducer array for bite holes after
every procedure. You should perform bite hole detection after cleaning the transducer, but before
disinfecting it, so you can identify punctures before exposing them to disinfectants which might leak inside
and damage the transducer.
Preparing for bite-hole testing
Test both the scan head and the endoscopic shaft separately for bite holes. You can use the same equipment
for both tests; however, the tester connection points are different for each test.
WARNING To avoid injury to the patient, do not use the transducer if the insulating
material has been punctured or otherwise compromised.
WARNING Take all necessary precautions to avoid contact with non-insulated parts that
have applied voltage.

4 Testing for bite holes
Assemble the following items for this 2-step test:
Water bath with a 5% saline solution (50g NaCl/1 liter water)
A conductor plate made of copper or aluminum with an area of at least 25 cm2 (one is included with bite
hole indicator kit)
Bite hole indicator with leads
Puncture test tool (included only with the TEExi and TEExp transducers)
Step 1 — Testing the transducer array (TEEx, TEExi, and TEExp)
To test the transducer array for bite holes or current leakage
Figure 1 Transducer array test setup
1After securing the controller so it does not fall into the water bath, immerse the scan head and endoscopic
shaft in liquid to above the 40 cm mark, but below the 90 cm mark.
2Connect the Bite hole indicator to the transducer connector and the conductor plate:
WARNING Do not immerse the controller, cable, or connector in any fluid.
Caution Do not allow the endoscopic shaft to contact the conductor plate. Doing so
could result in an inaccurate test result.

bIdentify the model of TEE transducer you are testing by checking the part number label on the
connector. The top line of the label will include the model name.
This information will be important in the next step.
Note Use the lead attached to the conductor plate. Do not submerge the indicator
clip.

cConnect the red leads to the knurled socket cap screws on the transducer connector as shown in
Figure 3. The configuration of the leads depends on the model of transducer you have. See step 2b to
determine your transducer model.

3On the Bite hole indicator, press
4Read the test result:
Leads - The leads are not connected correctly. Check the connections, and test again.
Fail - There was a bite hole detected in the transducer array. Stop the bite hole test procedure. Do not
use the transducer. For remediation steps, see “If the transducer fails the test” on page 10.
Pass - No bite holes were found.
All - If all of the lights are illuminated, the battery is low. Replace the battery.
If you are testing the TEEx transducer, proceed directly to “Step 3 — Cleaning the transducer (TEEx,
TEExi, and TEExp)” on page 9.
If you are testing the TEExi or TEExp transducer, continue with “Step 2 — Testing the endoscopic shaft
(TEExi and TEExp only)” on page 7.

Note Use the lead attached to the conductor plate. Do not submerge the indicator
clip.
Note Each clip should be attached separately to the puncture test tool.
