Figure 6-6. P8-3TEE Transducer
Intended Use The physician conducting the examination must exercise sound medical
judgement in the selection of patients for this transducer and be properly trained in
endoscopic techniques as prescribed by current medical practices. The P8-3
TEE
transducer is intended to be used on adult patients.
The TEE examination is performed to give the physician a more extensive
examination of the heart than could be obtained with standard transthoracic
imaging. The transducer is inserted into the esophagus or stomach of the patient
and is used to obtain 2-D, M-Mode, PW, CW, and Color Doppler images of the
heart.
WARNING: The P8-3TEE transducer should be used only by a qualified physician
who has received appropriate training in proper operation of the transducer and in
endoscopic techniques as dictated by current relevant medical practices.
Visual
Examination
Before use, visually examine and feel all portions of the transducer, especially the
gastroscope shaft and the flexible section at the distal end of the gastroscope.
Inspect the flexible section with the transducer deflection both straight and
deflected. There should be no discontinuities, bumps, dents, holes, abrasions,
bite-marks, or any other evidence of wear or damage found.
The hard plastic section at the distal end of the transducer should be smooth and
firmly attached to the gastroscope shaft.
The cable and the connector that attach the transducer to the ultrasound console
should be free from evidence of damage.
Check the proper mechanical operation of the transducer. Rotate the scan plane
with the push-buttons on the handle (see
“Transducer Scan Plane Rotation
Control” on page 6-11). Make sure the rotation is smooth for all scanplanes.
Deflect the tip in both anterior/posterior and left/right flexon using the deflection
control wheel on the handle (see
“Friction Lock Operation” on page 6-10). Make
sure the deflection operates smoothly.
