4-7. Puncturing precautions
Warning
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 equipment must be cleaned, disinfected and sterilized before use.
Be sure to always properly clean, disinfect and sterilize after use.
Otherwise, an infection can occur. Note that the equipment is not sterilized when shipped from the
factory. Before using the equipment, be sure to clean, disinfect and sterilize it as required.
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.
This needle guide, the guard plate and the lock plate are used by attaching them to the probe and
following the instructions in this manual.
Attaching them improperly to the probe or performing puncture operations without attaching them
to the probe can result in the needle guide, the guard plate and the lock plate coming off during sur-
gery or in puncturing of an unintended body part. For details on the attachment procedure, see sec-
tion 4-2 "Attaching of the needle guide, the guard plate and the lock plate".
For the acoustic medium, use sterilized physiological saline solution.
Using an unsterilized acoustic medium can cause an infection on the patient.
Check that the gauge size of the puncture needle that is used matches the gauge size of the needle
guide.
Using when the gauge sizes of the puncture needle and the needle guide do not match can result in
puncturing of an unintended body part. Also, even if the gauge size is the same, the diameters may
vary between different puncture needle manufacturers and products.
For puncture needles diameters can be used for the needle guide, see section 2-2-2 "Specifications
of the needle guide".
Use sterilized puncture needles.
Otherwise, an infection can occur.
Do not use needles were bent.
Puncturing of an unintended body part causing an injury to the patient.
Be careful when handling the puncture needle.
Accidentally puncturing your hand or other body part can result in infection of the operator or
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 an injury to the patient. Display the puncture guide
line on the screen referring to the instruction manual supplied with the ultrasound diagnostic
instrument, use it as an aid in determining the puncturing direction.
Check beforehand any areas not displayed on the ultrasound image that are along the puncturing
path.
If other tissues are in the area not displayed on the ultrasound image, there is a risk of puncturing an
unintended body part and causing an injury to the patient.
