

CAUTION: Devices containing latex may cause severe allergic reaction in latex

sensitive individuals. Refer to FDA's March 29, 1991, “Medical Alert on Latex

Products.”

■

Place the biteguard on the gastroscope prior to transducer insertion for easy

placement in the patient's mouth. The biteguard can also be placed in the

patient's mouth before inserting the gastroscope and transducer.

WARNING: The use of a biteguard is mandatory. Failure to use the biteguard may

result in damage to the transducer, which could result in a safety hazard. Damage

to the transducer due to biting is not covered by the transducer's warranty.

■

Apply a sufficient amount of water-soluble acoustic coupling gel on the

transducer tip.

CAUTION: Only use water-soluble acoustic coupling gel. Other coupling gels

containing ingredients like ethanol, mineral oil, iodine, lotions, lanolin, aloe vera,

or methyl or ethyl parabenzoic acid can cause transducer damage.

■

If used, place the latex sheath over the gastroscope shaft up to but not

covering the handle. Rub the tip carefully to ensure that all air bubbles have

been removed from the transducer's tip. In addition to the gel on the acoustic

window, apply a sufficient amount of acoustic coupling gel on the outside of the

sheath at the tip of the transducer.

CAUTION: Do not exert force on the acoustic window area.

Patient

Selection

There are some considerations in patient selection for safe use of the transducer:

■

Any history of esophageal disease, problems with swallowing, or reasons for

not accommodating the transducer must be considered as well as the possible

effects of other therapies the patient is undergoing concurrently.

■

Patients with dentures should remove them before the procedure.

■

The P8-3TEE transducer should not be used on children.

Deflection and

Scan Plane

Rotation

Control

■

The control handle has two wheels for deflecting the TEE tip. The handle is

designed for one-hand operation of deflection and rotation of the

TEE tip.

■

The smaller lower wheel is used to control the transducer Left/Right tip

deflection (see

Figure 6-8). The larger wheel on top of the handle is used to

control the transducer Anterior/Posterior tip deflection. Both wheels have a

friction lock and freely moving mode.

■

In the locked mode, the movement of the deflection wheel is restrained. This is

used to hold the tip in a certain position.

• A metallic ring around the body of the handle, which clicks ON/OFF, controls

the lock of the Right/Left tip deflection.

• A shifting bar in the larger knob controls the lock of the Anterior/Posterior

tip deflection.

• On the side of the control handle are two buttons used for rotating the scan

plane counterclockwise and clockwise between 0° and 180°.
