HIGH FLOW INSUFFLATION UNIT UHI-3
−
If the insufflator emits a warning (warning light or alarm)
for intra-abdominal over-pressurization, quickly open the
stopcock or valve of the trocar.
In this event, reduce the amount of outflow from the laser
device, argon-enhanced coagulator, or other gas supply
device.
If use is continued while the alarm is sounding, there is a
risk of gas embolism due to intra-abdominal
over-pressurization.
• When relief mode is set to ON, the intra-abdominal gas will
flow backward into the equipment for relief through the
built-in valve. To prevent the internal surfaces of the
equipment from being contaminated, be sure to use a
disposable filter. When no filter is used, make sure relief
mode is set to OFF.
• When relief mode is set to ON, the relief function will operate
if an additional veress needle or trocar, etc. is inserted (due
to the momentarily high abdominal pressure). To disable the
relief function from activating, press the stop switch.
1.
Turn the power switch ON to check the status of the current relief mode. The
relief mode indicator lights when the relief mode is active. The default
setting is ON.
2.
To change the relief mode, turn on the POWER switch while pressing the
RESET switch. Continue pressing the RESET switch for several seconds to
change the relief mode.
3.
When relief mode is set to ON: When the abdominal pressure is 5 mmHg or
more above the set value, the gas is released through the internal channel
until the abdominal pressure readout reaches the desired setting.
4.
When relief mode is set to OFF: Gas release through the internal channel
does not work.
