6-14 z.one ultra and z.one ultra sp OPERATOR MANUAL

■

Prolonged pressure on the esophagus by the tip of the transducer may lead to

a pressure necrosis phenomenon. Thus, in monitoring applications, the tip

should be removed from the esophagus wall when you are not scanning by

releasing it in the neutral position. If continuous monitoring is required, the

transducer tip should often be repositioned.

■

Whenever active scanning is not desired 'freeze' the image and release the

deflection control.

■

Position the array so that good acoustical contact is made. Before rotating the

array, actuate the friction ('brake') on the up/down movement. If this is not

done, rotating the array can mean loss of acoustical contact.

TEE – Care and Maintenance

NOTE: The following sections are for TEE transducer maintenance only.

See “Transducer Maintenance” on page 14-20 for information on maintaining,

cleaning, and disinfecting all other ZONARE transducers.

Inspecting

Transducer

WARNING: Regularly check transducer for signs of wear or damage. Inspect

transducers at least weekly for the following problems:

■

Cracks in case or transducer face.

■

Cuts or gouges on any part of the transducer, case, cable, and connector.

■

Cracks in the lens material on the transducer face.

■

Any cracks or damage to the transducer connector.

■

Proper mechanical operation of the transducer. Rotate the scan plane with the

push-buttons on the handle. Make sure that the rotation is smooth for all scan

planes. Deflect the tip in both anterior/posterior and left/right direction using

the deflection control wheel on the handle. Make sure the deflection operates

smoothly.

■

Anterior/posterior and/or left/right deflection, which may, after prolonged use,

develop an unwanted amount of free play. In that case, contact the service

organization to readjust the tip deflection of the transducer. In this way, the risk

of “buckling” or “U-turning” of the transducer in the esophagus is minimized.

WARNING: Inspect the transducer connector pins for any damage that might

interrupt signal flow through the connection. Be sure to check pins before

connecting transducer to the

ZONARE ultrasound system (see Figure 6-3 on

page 6-3). If pins are recessed, do not use the transducer and call ZONARE

Technical Support.
