4-6. Puncturing precautions
Warning
Carefully read the usage precautions in the documentation supplied with the needle guide bracket.
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 ultrasonic diagnostics and who is skilled and has a
thorough knowledge of puncture operations under an ultrasonic guide.
The needle guide bracket must be properly mounted on the probe during use.
Puncturing with the needle guide bracket improperly mounted or the needle guide bracket uninstalled
can result in the needle guide bracket coming off during puncturing or puncturing of an unintended
body part, causing injury to the patient. For details about the needle guide bracket mounting procedure,
see the documentation supplied with the needle guide bracket.
Equipment that contacts the patient during puncturing must be sterilized.
Use of unsterilized items can cause an infection. For details concerning the equipment sterilization
procedure, see the documentation supplied with the equipment.
For the acoustic medium, use sterilized acoustic medium.
Using an acoustic 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 puncturing of an unintended body
part, causing injury to the patient.
For the compatible puncture needle sizes, see the documentation supplied with the needle guide
bracket.
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 puncture 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.
Before using a needle cannula with the needle guide bracket as a guide, first check that the cannula
moves smoothly through the bracket without causing any damage on the surface of the cannula and
then operate with caution.
If the cannula does not move smoothly or is forced to bend when inserted in or pulled out of the
needle guide bracket, it may damage the insulation membrane covering the cannula and may cause
burns to the tissue exposed to the damaged area of the cannula.
When puncturing, be sure to wear sterilized medical gloves.
Puncturing with the bare hands can expose the operator or patient to a risk of infection.
For details about the reuse and disposal of puncturing needles, follow the instructions in the
documentation supplied with the puncturing needles.
Reuse of puncturing needles that are not reusable or improper disposal could result in an infection.
