Application Scope, Operation Conditions, Safety and Cautions
1-5
i) For instructions on probe disinfection and protection, follow the description in 4.2.9;
j) It is prohibited to scan eyes with the probe. Keep the acoustic power as low as
reasonably achievable (ALARA). Scan the body only in a period required for making
the diagnosis, rather than scan the body for a long time. An extended scan might
result in harm to personal health. Provided that clinical indications are required, the
system operator shall be fully acquainted with acoustic output or be accessible to
relevant thermal index. Pay special attention to minimize exposed acoustic power and
exposure period when used on an embryo or a fetus. The endocavity probe, when
exposed in the air and noticeable heat from the probe itself, should not be applied to
endocavity exam;
k) To ensure safety, only qualified ultrasound coupling gel compliant to relevant
standards shall be applied;
l) During examination, in case images are interfered by an AC noise ( the power supply
to the system is from the adapter ) due to the patient, put a shield sheet between the
body and the bed as shown in Fig.1-1, and connect the sheet to the equipotential
terminal of the main unit. The hum-hum interference noise can be eliminated;
m) The system operator should not touch any tangible metal parts of any electronic
device in the patient environment and the patient at the same time;
n) The system does not provide special protection functions or measures for use with
high frequency surgery equipment. The user should be cautious of such application;
o) Shut down the system in correct procedures, otherwise it might result in system data
loss or system failure;
p) Except for the USB port, do not disconnect the system or any other peripheral device
(e.g. a printer) from any plug before the system is turned off, otherwise it may result in
system damage or electric shock;
q) The system is not intended for use with a defibrillator;
r) The system shall not be applied to cardiology directly;
