5.8 Ultrasonic probe check before and after operation
Before and after ultrasonic diagnosis to check if there are any exceptionally on the surface of the
probe or cable jacket, such as peeling, cracks, bulge, or if the acoustic lens is reliable, cleaned or
disinfected.
5.9 Main unit check before and after operation
5.9.1 Inspection before start-up
Check the following items before starting the machine:
1. The temperature, humidity and atmospheric pressure shall meet the requirement of operation
conditions.
2. No condensation occurs.
3. No distortion, damage or contamination on system and peripheral. Clean the parts as specified
in relevant sections, if the contaminant is present.
4. Check the control panel, LCD screen and enclosure to ensure they are in good working
condition and free of abnormity (such as cracks and loosened screws).
5. No damage on cable (such as power cable), and hard up on its connection.
6. Check probe and its cable to ensure they are free of abnormity (such as scuffing, drop-off or
contamination). If the contaminant is present, clean the contaminated objects as specified in
relevant sections.
7. See to it that there are no foreign objects on the control panel (Remove the object if any).
8. No barriers around the intake of equipment.
9. See to it that whether probe has been cleaned, disinfected; else dispose it as specified in
relevant sections.
10. Check all the ports of the machine for possible damage or blockage.
11. Clean the field and environment.
5.9.2 Inspection after start-up
Check the following items after starting the machine:
1. No abnormal voice, strange smell and overheating appear.
2. Check the machine to ensure a normal start-up: The power indication light is on; startup
picture is shown on the screen, and then the machine will automatically enter B mode.
3. Check the acoustic lens for abnormal heat when the probe is in use. This can be done by hand
touching the probe to feel the temperature of the lens.
4. Check the image to ensure trouble-free display (no excessive noise or flicker).
5. Check the control panel to ensure normal operation condition.
6. Check the instrument to ensure that the phenomenon of too high local temperature will not
appear.
5.10 System reset
In case of abnormal screen display or not work for system operation, try to restart the system by
turning on/off the power.
Attention:
Thoroughly clean the coupling gel on the probe surface each time after
ultrasonic operation, or the coupling gel may become hardened on the acoustic lens of the
probe, deteriorating quality of image.
Attention:
If the overheat acoustic lens is placed on the patient’s skin, heat injury may
occur.
