2. Specifications and Parts name

2-1. Principles of operation

This probe and the ultrasound diagnostic instrument enable image diagnosis using ultrasonic waves. These

instruments operate under the principles described below.

(1) W hen an electric pulse signal is applied from the transmitter to the transducer of the probe, the transducer

operates by converting electrical vibrations to mechanical vibration energy for emitting pulse-shaped

ultrasonic waves into the body part contacting the transducer or into liquid or other medium.

(2) The emitted ultrasonic waves are reflected by boundaries with different acoustic characteristics (acoustic

impedance) within the body.

(3) The transducer is also used to receive reflected ultrasonic waves. The transducer vibrates mechanically due

to the received ultrasonic vibrations and uses an electro-mechanical conversion operation to convert the

received mechanical vibrations to electric energy. The received echo is also converted to electric signals

and a brightness modulation operation is used to convert the electric pulses to shades of brightness for

forming an image.

4-4. Precautions when performing puncture operations

Warning

Carefully read the usage precautions in the documentation supplied with the puncture adapter.

Be sure that the preparations for use are completed before using.

Puncturing must be performed by a skilled doctor.

Improper puncturing can injure the patient. Puncturing operations must be performed by a doctor

who fully understands the characteristics of ultrasound diagnostics and who is skilled and has a

thorough knowledge of puncture operations under an ultrasound guide.

The puncture adapter must be properly mounted on the probe during use.

Puncturing with the puncture adapter improperly mounted or the puncture adapter uninstalled can

result in the puncture adapter coming off during puncturing or puncturing of an unintended body

part, causing injury to the patient. For details about the puncture adapter mounting procedure, see the

documentation supplied with the puncture adapter.

Be sure that the puncture adapter and the needle are sterilized before use.

Use of unsterilized items can cause an infection. For details concerning the puncture adapter

sterilization procedure, see the documentation supplied with the puncture adapter.

For the acoustic medium, use sterilized physiological saline.

Using an unsterilized ultrasound medium can cause an infection on the patient.

Use a compatible puncture needle size.

Use of a puncture needle that is not a compatible size can result in the puncture adapter coming off

during puncturing or puncturing of an unintended body part, causing injury to the patient. For the

compatible puncture needle sizes, see the documentation supplied with the puncture adapter.

Always use a straight needle.

Puncturing of an unintended body part can cause injury to the patient.

During the puncture operation, display a suitable puncture guide line on the screen of the ultrasound

diagnostic instrument.

Puncturing of an unintended body part can cause injury to the patient. Display the puncture guide

line on the screen referring to the documentation supplied with the ultrasound diagnostic instrument,

to use it as an aid in determining the puncturing direction.

Constantly check the safety in the needle insertion direction using the needle echo rendered by the

ultrasonic wave.

A bent puncturing needle can result in puncturing of an unintended body part and cause injury to

the patient.

Check that no other organs lie in the puncture path.

If another organ lies in the puncture path, an unintended body part can be punctured and cause injury

to the patient. Before puncturing, carefully check the body parts and constantly confirm the needle

echo during the operation.

Do not try to forcibly perform operations.

If excessive force is applied in a direction other than the insertion direction of the puncturing needle,

the puncturing needle can come off the guide line, resulting in puncturing of an unintended body

part, causing injury to the patient.
