HIGH FLOW INSUFFLATION UNIT UHI-3
UHI-3 main unit
Item
Specification
Applicable gas
• CO
2
gas for medical use.
• Connection to gas cylinder via the Olympus
cylinder hose (PIN) for UHI-3 (MAJ-1080)
• Connection to medical gas pipeline via the
Olympus medical gas pipeline adaptor for UHI-3
(MAJ-1084 (NIST), MAJ-1085 (DISS))
• Pressure range of medical gas pipeline
–upper limit: according to ISO 7396 (1400 kPa)
–lower limit: 343.2 kPa (3.5 kgf/cm
2
)
• Hose for medical gas pipeline is required to
comply with ISO 5359 (NIST or DISS)
Supply pressure indications
• Five steps by LEDs.
5: above 4.5 MPa
4: 3.5 to 4.4 MPa
3: 2.5 to 3.4 MPa
2: 1.5 to 2.4 MPa
1: 0.5 to 1.4 MPa
Alarm:
• When the cylinder pressure is lower than
2.4 MPa, an intermittent alarm (1 second) will
sound.
• Whenever the cylinder pressure drops 0.5 MPa,
an intermittent alarm (1 second) will sound.
• When the cylinder pressure is 0 MPa, CO
2
insufflation will stop, the cylinder pressure
indicator will light red and an intermittent alarm
(3 second) will sound.
