4.2 Preparing the probes for scanning
• An effective acoustic coupling does not require
inordinate pressure, but it does require coupling gel
and patient contact.
• Check the expiration date of the probe sheath and the
coupling gel. Never use expired probe sheath and
coupling gel.
• Latex or natural rubber contained inside medical
equipments or accessories can cause severe allergic
reactions in some individuals. It’s suggested by FDA
that the user should identify the latex-sensitive patients
and be prepared to treat allergic reactions promptly.
• Only water-soluble coupling gel should be applied to
the probe head surface. Avoid contact with the mineral
oil.
Put an adequate amount of coupling gel either on the probe head
(acoustic window) or the patient skin.
If disease transmission is a concern, use of the sterile probe
sheath is highly recommended. Refer to instructions below
to cover the probe surface with probe sheath.
Mounting biopsy guide (optional)
