HIGH FLOW INSUFFLATION UNIT UHI-3
1.
Lamp for relief mode
This lamp lights when relief mode is activated.
2.
Set pressure indicator
This indicator shows the set pressure in green digits.
3.
Abdominal pressure indicator
This indicator shows the abdominal pressure in red digits.
4.
Warning lamp for excessive pressure
This lamp lights when abdominal pressure reaches 5 mmHg or more above
the set pressure.
5.
Set flow rate indicator
This indicator shows the set flow rate in green digits.
6.
Actual flow rate indicator
This indicator shows the actual flow rate in red digits.
7.
Warning lamp for tube obstruction
This lamp lights when insufflation tube is blocked or clogged, or when
insufflation is performed into an abnormally narrow cavity.
8.
Volume indicator
This indicator shows the volume of gas used.
9.

This graph shows the current flow rate.
10.
Lamp for flow mode indication
These lamps light when the corresponding flow mode is selected.
11.
Bar graph for abdominal pressure
Blinking green LEDs shows the set pressure. A green bar shows the
abdominal pressure. If abdominal pressure exceeds the set pressure, the
excess is displayed in red.
12.
Bar graph for supply pressure
This bar graph shows the pressure of the connected supply gas. When the
pressure is below 2.5 MPa, the alarm sounds. When the pressure is low and
the CO
2
gas is not insufflated, an alarm sounds and a red LED lights.
13.
