3-3-1. Check preparation
(1) Required items
Tub (Depth of 20 cm or more)
Warm water 40°C (104°F)
Thermometer
Puncture guide tube MP-2452-G18 (standard configuration)
or others (user’s selection of the options)
Puncture needle Size: 18G (standard configuration) or others (depend on a user’s selection)
Length: up to 250 mm
(2) Setup procedure
1. Put warm water at 40°C (104°F) into the tub.
Use a thermometer to check the water temperature.
2. Refer to section 4-1 “Operation”, and attach the puncture guide tube to the probe,
and insert the puncture needle into the puncture guide tube.
Check that the puncture needle has no bending or other defects.
3. Connect the probe to the ultrasound diagnostic instrument.
Turn on the ultrasound diagnostic instrument to display the puncture guideline on the monitor screen.
Remarks: For details of the puncture guideline, refer to the instruction manual of the ultrasound diagnostic
instrument.
Caution
Use warm water at 40°C (104°F) in the check of the needle echo.
In the actual puncture operation, the needle echo and guideline may not match and this could result in
puncturing of an unintended body part. It is well-known that the acoustic characteristics of water at
40°C (104°F) are the most similar to those of the human body.
