HIGH FLOW INSUFFLATION UNIT UHI-3
4.6
Inspection of UHI-3 operation when using a
veress needle/trocar
• If the tube obstruction alarm or the excessive pressure alarm
sounds, or if the abdominal pressure indication increases,
the veress needle or trocar is damaged or not compatible
with the UHI-3. Do not use incompatible veress needles or
trocars.
• If you suspect that the filter is damaged, remove the filter
from the insufflation tube, connect the insufflation tube
directly to the CO
2
gas feed connector and begin insufflation.
If the problem no longer exists, the filter is damaged; do not
use it. Replace it with a new filter.
1.
Connect the veress needle or trocar to the luer-lock connector attached to
the insufflation tube. Then connect the insufflation tube to the CO
2
insufflation connector on the UHI-3.
When a filter is used with the device, place the filter between the insufflation
tube and the filter connecting tube.
2.
Set the gas flow rate to LOW and press the start switch. Confirm that
insufflation is performed through repeated cycles of insufflation and pauses.
