Important Information — Please Read Before Use
HIGH FLOW INSUFFLATION UNIT UHI-3
• Other possible complications include CO
2
embolization,
hypothermia and carbonic acid irritation of the diaphragm.
Direct access of insufflated CO
2
gas to the vascular system
(e.g. through an open vessel in the intra-abdominal cavity, or
an improperly inserted veress needle) may result in gas
embolism.
• Operative procedures should only be performed with
insufflators capable of flow rates of at least 4 – 10 L/min.
Insufflators with lower maximum flow rates should only be
used for diagnostic procedures.
Before using a veress needle and trocar, inspect the items as
outlined in Section 4.6, “Inspection of UHI-3 operation when
using a veress needle/trocar”.
As defined by the international safety standard
(IEC 60601-1), medical electrical equipment is classified into
the following types: Type CF applied parts (the instrument
can safely be applied to any part of the body, including the
heart), and Type B/BF applied parts (the instrument can
safely be applied to any organ except the heart). Which part
of the body the endoscope or accessories can safely be
applied to depends on the classification of the equipment to
which the instruments are connected. Before beginning the
procedure, review the current leakage classification type of
each instrument that you will use for the procedure.
Classification types are clearly specified on the instruments
and in the instruments’ instruction manuals.
