HIGH FLOW INSUFFLATION UNIT UHI-3
• Should blood, etc., back flow into the insufflation tube, make
sure that it does not enter the UHI-3. Should any body fluids
enter the UHI-3, immediately terminate its use and contact
Olympus.
• When a filter is used with the device, backward flow of body
fluids (e.g. blood) may clog the filter. If body fluids flow
backward, stop insufflation immediately and replace the filter
with a new one.
When a filter is used with the device, connect the insufflation
tube to the UHI-3 as described in “Connecting an insufflation
tube (MAJ-590, MH-397)” on page 30.

Relief mode
• 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. In these
cases, 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.
