Table 1 Name of each part and its explanation

Name Explanation

Ultrasound radiation part Ultrasound is radiated from this part. The electronic

linear transducer is integrated underneath this part.

Front mark The side of the circular mark corresponds to the side of

the orientation mark on the image.

Transducer center mark This is the mark for the center of the transducer.

Transducer position mark This is the mark for the edge of the transducer.

Probe tip This part is gripped during operation.

Cable Cable transfers electric input/output signals.

Connector The connector is the part which connects the probe and

the ultrasound diagnostic instrument.

Caution

Do not pull, bend, twist, or apply excessive force to the cable.

The probe may malfunction due to cable disconnection.

Do not subject the ultrasonic radiation part to hard impact.

The impact may cause damage to the transducer, and that results in noise or no echo in the image.

In most cases, the ultrasonic radiation part itself is not damaged because the part is made of elastic

material.

3. Preparations before use

This chapter describes preparations needed to use the probe safely. Please prepare the probe prior to each use by

following the instructions below.

3-1. Visual check

Visually check the probe tip, ultrasonic radiation part, cable, and connector.

If any holes, indentations, abrasion, cracks, deformation, looseness, discoloration, or other abnormalities are found, do

not use the probe.

3-2. Conrmation of cleaning, disinfection, and sterilization

Conrm that the probe is certainly cleaned, disinfected, and sterilized. The degree of reprocessing depends on the

intended use. Please refer to the separate instruction manual “Cleaning, Disinfection and Sterilization“ for cleaning,

disinfection, and sterilization procedure.

3-3. Operation check

Connect the probe to the ultrasound diagnostic instrument and check that the displayed scan type and frequency

correspond to those of the probe. Check also that there is no abnormality in the image.

Remark: Please refer to the documentation supplied with the ultrasound diagnostic instrument for how to connect the

probe and information displayed on the monitor.

If the probe is operated in still air, brightness on the top of the image may be non uniform, but this does not

affect the performance of the probe.

Warning

Make preparations prior to each use.

The operator and the patient may be injured if the equipment has any abnormality.

If any abnormality is found in the equipment, stop using it and contact our ofce written on the back

cover.

Caution

Do not use the probe if the displayed scan type and frequency do not correspond to those of the probe.

Incorrect acoustic output can result in burns or other injuries to the patient. Contact our ofce written

on the back cover.
