4-8. 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 ultrasonic guide.
Clean, disinfect and sterilize before using the equipment.
Perform proper cleaning, disinfection and sterilization after use.
Otherwise, there is a risk of infection. Note that the equipment is not sterilized at the factory.
Before using the equipment first, be sure to clean, disinfect and sterilize it.
When puncturing, be sure to wear sterilized medical gloves.
Puncturing with the bare hands can expose the patient or operator to a risk of infection.
This puncture guide tube is used by attaching it to the probe and following the instructions in this
manual.
By attaching it improperly to the probe or performing puncture operations without attaching it to the
probe can result in the puncture guide tube coming off during puncturing or puncturing an unin-
tended body part. For details on the attachment procedure, see section 4-4 "Attaching of the punc-
ture guide tube".
For the ultrasound medium, use sterilized physiological saline solution.
Using an unsterilized ultrasound 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 puncture
guide tube.
Using when the gauge sizes of the puncture needle and puncture guide tube 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 details on the puncture needle diameters that can be used in the puncture guide tube supplied
with the probe, refer to section 2-2-2"Specifications of the puncture guide tube". For details on the
puncture needle diameters that can be used in optional puncture guide tubes, see the documentation
supplied with the puncture guide tube.
Use sterilized puncture needles.
Otherwise, an infection can occur.
Do not use needles were bent.
It can result in puncturing of an unintended body part causing 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 documentation supplied with the ultrasound diagnostic instrument,
to use it as an aid in determining the puncturing direction.
