HIGH FLOW INSUFFLATION UNIT UHI-4
Supply pressure indications • Five steps by LEDs.
5: above 4.5 MPa
4: 3.5 – 4.4 MPa
3: 2.5 – 3.4 MPa
2: 1.5 – 2.4 MPa
1: 0.1 – 1.4 MPa
Alarm:
• When the cylinder pressure is lower than
2.5 MPa, an intermittent guidance sound
(1 second) will sound.
• When the cylinder pressure is lower than
1.5 MPa, an guidance sound will sound again.
• When the cylinder pressure is below 0.1 MPa,
CO
2
insufflation will stop, the cylinder pressure
indicator will light yellow and an intermittent alarm
(3 second) will sound.

insufflation
• Automatic suction/relief/smoke evacuation
(optional)
Cylinder pressure, flow rate indicators

Settings, cylinder pressure, and volume displayed.
Selection of the cavity mode • Select the cavity mode.
• “NORMAL” cavity mode for endoscopic
observation and treatment of the abdominal
cavity.
• “SMALL” cavity mode for observation and
treatment of the small cavity
(Example: colon (rectum)).
Cavity pressure control When cavity pressure reaches the set pressure
level, insufflation will stop. When cavity pressure
drops below the set pressure level, insufflation will
start.
