HIGH FLOW INSUFFLATION UNIT UHI-3
Abdominal
pressure
alarm
Excessive
pressure
• An alarm will sound and the warning lamp for
Excessive Pressure will light if the abdominal
pressure exceeds the set pressure by 5 mmHg or
more.
• If the condition described above continues for
10 seconds or more, suction will be activated.
Suction will stop when the abdominal pressure is
reduced to the set pressure.
Tube
obstruction
If the tube or filter is obstructed, or insufflation is
performed into an abnormally small cavity, e.g.
subcutaneously, insufflation will be interrupted and
the warning lamp for tube obstruction will light. The
alarm will sound until the obstruction is removed.
Relief mode When relief mode is set to ON (active) and the
abdominal pressure is 5 mmHg or more above the
set pressure, relief the gas through the internal
channel until the abdominal pressure readout
reaches the set pressure.
Flow rate control • As long as there is a difference between
abdominal pressure and the set pressure,
insufflation is performed at the set flow rate.
• As the abdominal pressure approaches the set
pressure, the flow rate is gradually decreased.
• When the abdominal pressure reaches the set
pressure, insufflation will stop.
Flow rate
indications
Setting
indications
Flow rate indicator: Green indication of the set
pressure.
Actual value
indication
Flow rate bar graph: Green indicates the CO
2
gas
flow (instantaneous flow rate).
(All LEDs up to instantaneous flow rate value will
light.)
Flow rate indicator: Red indicates the flow rate
value.
Flow rate
settings
3 flow setting
modes:
“HIGH” mode: 20 – 35 L/min
“MED” mode: 1.1 – 19 L/min
“LOW” mode: 0.1 – 1.0 L/min
Previous flow
rate setting is
retained.
When power is turned ON, “LOW” mode is
selected.
