HIGH FLOW INSUFFLATION UNIT UHI-3
3.4 Connecting the medical gas pipeline adaptor
(MAJ-1084/1085)
Using gases other than medical grade CO
2
may result in fire,
poisoning, complications, etc. In addition, oil, impurities, etc.,
may penetrate into the interior of the UHI-3 and impede
proper CO
2
gas insufflation.
• Connect the gas supply hose to the UHI-3 before connecting
it to the CO
2
gas connector. Otherwise, there is a danger of
significant gas leakage.
• Never lubricate the connecting sections of the UHI-3, the
adaptor and the medical gas pipeline with grease, oil, etc.
This could result in grease, oil, or other foreign matter
entering the UHI-3, impeding proper operation and
preventing proper insufflation of CO
2
gas.
• For proper insufflation of the CO
2
gas, confirm that the
pressure of medical gas pipeline is over 343.2 kPa
(3.5 kgf/cm
2
) and below than the upper limit given in
ISO 7396 (1400 kPa).
Use MAJ-1084 for NIST type fittings, and MAJ-1085 for DISS
type fittings. Do not use any other hoses than those
specified.
Olympus does not sell medical gas pipeline hoses. Use an
appropriate hose for the medical gas pipeline being used.
