UHI-4 Insufflator Quick Reference Guide
Insufflator Controls Cavity Modes
Flow Rates
There are two cavity modes Normal and Small which regulate the pressure and flow rates.
The are three flow settings:
Note: The cavity mode cannot be changed once insufflation has started, if required stop
insufflation and then change mode.
Warning: when using a Veress needle always use the LOW flow mode as insufflation in other
modes is dangerous because the cavity pressure may exceed the set pressure.

Cavity mode Setting pressure range Note
NORMAL 3 - 25 mmHg
(0.4 - 3.3 kPa)
To increase the pressure from 20
to 21 mmHg, keep pressing “+”
for at least three seconds

(0.4 - 2.0 kPa)

Smoke Evacuation Smoke Evacuation
Use the MAJ-1939 foot switch for smoke evacuation. The smoke and mist generated inside the
cavity can be exhausted while maintaining the cavity pressure.
• In the sterile field cut the luer lock end of the tubing (WA95007A) and connect to a ULPA
filter, attach to a secondary port and open the tap.
• Attach the thinner diameter tubing into the green suction pinch valve on the UHI-4.
When used in combination with the
Olympus MAJ-1939 foot switch,
pressing the appropriate switch allows
this instrument to execute insufflation into
and suction from the cavity simultaneously
to exhaust and remove the generated
smoke and mist while maintaining the
cavity pressure constant. The flow can
be adjusted using the toggle button.
Note: Smoke evacuation will not work if:
• The flow rate on the insufflator is set to LOW
• When the high flow insufflation unit is in the gas flow stop mode.
• When this instrument is in the excessive pressure caution status.
• When this instrument is in the tube obstruction caution status.
Note: If the patient is a child whose cavity volume is small, the cavity pressure will fluctuate
greatly. Do not use the smoke evacuation function in such cases.
• Attach the blue end of the suction tubing to the suction device and activate suction on
this device.

Low or no pressure
• Check insufflation tubing connected to insufflator, switched on and tap on port turned on.
• Check gas level and that gas cylinder is turned on Increase flow rate or pressure.
Excessive pressure alarm continuously sounds
• The high pressure alarm will sound if the patient anaesthetics are no longer effective,
consult the anaesthetist.
Smoke Evacuation does not work
• Check the smoke evacuation speed is not set to OFF.
• The flow rate on the insufflator is set to MEDIUM or HIGH
