HIGH FLOW INSUFFLATION UNIT UHI-4
5.12 Steps after use
• When disconnecting the high-pressure hose from the gas
supply port on the rear panel and the CO
2
cylinder, be sure to
close the CO
2
cylinder valve and exhaust CO
2
remaining in
the instrument. Otherwise, a large amount of gas will jet out
of the instrument.
When disconnecting the high-pressure hose from the CO
2
gas inlet and CO
2
cylinder, ensure that the CO
2
cylinder
valve is closed, then release any residual CO
2
remaining
inside the high flow insufflation unit. The gushed
high-concentration CO
2
is hazardous and may cause
difficulty in breathing if inhaled.
• If blood and body fluid penetrate inside the insufflation tube
that is connected to the high-flow insufflation unit, be careful
not to bring the insufflation tube at a higher level than the
CO
2
feed port of the insufflation unit when disconnecting the
tube from the veress needle or trocar. Otherwise, the blood
and body fluid may enter the insufflation unit and
contaminate it.
• Stop insufflation from this instrument before disconnecting
the insufflation tube. Otherwise, since the insufflation does
not stop automatically, the CO
2
cylinder will become empty
and the indoor CO
2
level will increase.
• Increase in the indoor CO
2
level may exert unfavorable
effects on the operation staff. Be sure to ventilate the
operating room sufficiently.
• When unplugging the transducer plug or power cord plug,
always hold and pull the plug section. Pulling the cord may
result in an internal wire disconnection.
• After use, always inspect the high flow insufflation unit and
accessories to confirm that they are not damaged. Do not
use the ultrasonic generator or an accessory if it is damaged.
