HIGH FLOW INSUFFLATION UNIT UHI-3
• Position the patient port of the insufflator and as much of the
associated tubing as is practical above the insufflation site,
so that any patient fluids inadvertently entering the tubing do
not drain back into the insufflator via gravity.
• Always keep the gas cylinder in the upright position. Fasten
the cylinder to a wall or another stable structure to prevent it
from toppling. If the gas cylinder is placed horizontally or in
an inclined position, liquefied CO
2
may be transmitted into
the insufflation channel inside the UHI-3 and normal
insufflation may become impossible.
• 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 an 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 himself.
−
If the insufflator emits a warning (warning light or alarm)
for intra-abdominal over-pressurization, quickly open the
stopcock or valve of the trocar.
Then, reduce the amount of outflow from the laser device,
argon-enhanced coagulator, or other gas supply device.
If use is continued while the alarm sounds, there is a risk
of gas embolism due to intra-abdominal
over-pressurization.
