HIGH FLOW INSUFFLATION UNIT UHI-3
5.6 Automatic exhaust
This product, when combined with the UES-40 or the SonoSurg-G2 via aeration
cable MAJ-877, can exhaust fumes and mist generated in the body cavity by
synchronizing the ultrasonic or high frequency output and the exhaust function.
• When using the automatic exhaust, also refer to the
instruction manual of the UES-40 or the SonoSurg-G2.
Incorrect usage or equipment connection may compromise
the functionality and performance of this feature and could
lead to equipment damage and/or patient injury.
• Confirm that the suction tube is securely attached. If the
suction tube becomes disconnected, CO
2
discharge will not
be possible. In this case, further supply of CO
2
gas will
increase the abdominal pressure.
When the pedal of the foot switch for UES-40 (MAJ-1258) or SonoSurg-G2
(MAJ-51) is pressed, the exhaust function of the UHI-3 is activated to exhaust
fumes and mist. After the pedal is released, the exhaust function continues
operating for about 5 seconds. When the UHI-3 is set to stop mode, its flow
setting is LOW or abdominal pressure is below 3 mmHg, this function is
disabled.
• When the abdominal pressure exceeds the set pressure by
5 mmHg, the excessive pressure warning lamp will light and
an alarm will sound.
• High-frequency output is performed under the assumption
that only the insufflation tube is inserted into the patient after
the first trocar is inserted (therefore, no suction tube is
connected). In this case, select the LOW flow setting or press
the STOP switch to temporarily disable the automatic
exhaust function.
