4-6. Precautions when performing puncture operations
Warning
Carefully read the usage precautions in the documentation supplied with the puncture guide tube.
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 guide tube must be properly mounted on the probe during use.
Puncturing with the puncture guide tube improperly mounted or the puncture guide tube uninstalled
can result in the puncture guide tube coming off during puncturing or puncturing of an unintended
body part, causing injury to the patient. For details about the puncture guide tube mounting procedure,
see the documentation supplied with the puncture guide tube.
Be sure that the puncture guide tube and the needle are sterilized before use.
Use of unsterilized items can cause an infection. For details concerning the puncture guide tube
sterilization procedure, see the documentation supplied with the puncture guide tube.
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 guide tube 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 guide tube.
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 guideline on the screen of the ultrasound
diagnostic instrument.
Puncturing of an unintended body part can cause injury to the patient. Display the puncture guideline
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 guideline, resulting in puncturing of an unintended body
part, causing injury to the patient.
Caution
Handle the needle carefully to ensure that the probe or puncture guide tube is not damaged.
Using a probe or puncture guide tube that has been damaged by a needle can result in an injury to
the operator or patient.
