HIGH FLOW INSUFFLATION UNIT UHI-3
10.
The insufflation flow rate will diminish as the abdominal pressure
approaches the set pressure.
11.
To change the abdominal pressure setting during insufflation, adjust the
abdominal pressure control switches.
12.
To disconnect the insufflation tube and temporarily stop insufflation, press
the stop switch. To start insufflation again, press the start switch.

• To prevent gas embolism caused by intra-abdominal
over-pressurization from the combined use of an insufflator
and a laser device, argon-enhanced coagulator or other gas
supply devices, carefully read and understand the following
before using.
−
When performing laparoscopy using the insufflator and a
laser device, argon-enhanced coagulator or other gas
supply devices simultaneously, both instruments become
a source of supply for gas. Accordingly, the desired
pressure in the abdomen is reached in a shorter time than
when a pneumoperitoneum device is used alone. Be
careful that the abdomen does not become
over-pressurized.
The laser device, argon-enhanced coagulator and other
gas supply devices are not equipped to monitor the
abdominal pressure (automatic termination of insufflation,
warning light or alarm). Although the insufflator is
equipped with these functions, it does not always prevent
gas embolism inasmuch as this depends on the patient
and the condition of the infected area. We ask that the
physicians make a suitable judgment from a professional
standpoint.
