Olympus UHI-2
Olympus · Model UHI-2
Powerful 35 L/min. insufflations The UHI-3 features a powerful 35 L/min. high flow gas-supply. It can quickly respond to gas leakages to return to the preset pressure level Automatic relief When abdominal pressure becomes too high, a warning lamp and an alarm are activated, and a pinch valve on the suction tube opens automatically to release excess pressure Low noise design Noise is kept especially low through an innovative mechanism in the electromagnetic valve 3 main flow settings You can quickly set flow rate to programmed Low, Medium or High mode Check critical data at a glance Actual and preset pressures are displayed simultaneously. You can easily monitor necessary information, while remaining focused on what you are doing Connectable to medical gas pipeline The UHI-3 unique pressure control mechanism let you connect it to your hospital medical gas pipeline, eliminating the need for handling heavy, inconvenient gas cylinders Other advantages include. Built-in smoke evacuation feature smoothly removes smoke and mist while clearing the operative view, resulting in clear, concise and focussed surgery. Powerful 35ltMin flow. 3 flow rate settings of Low, Med and High. Audible and visual pressure warnings for added safety. Large, easy-to-read front display panel for clear and easy monitoring of variations. 3 Way CO2 adaptor available allowing 2 gas bottles to be connected and switched between intra-operatively.
Key tips
- ·A failed leak test means the scope does not get reprocessed or used - send it for repair, full stop.
- ·A shortened reprocessing cycle is a real infection-control failure, not a minor deviation - follow AAMI ST91 exactly.
- ·Track light-source lamp-hours against the manufacturer's limit rather than running to failure.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Will not reach or hold set intra-abdominal pressure
HighSymptoms: Pressure alarm, insufflation stops, cannot maintain pneumoperitoneum, high-flow alarm.
Root cause: CO2 supply low, a leak in the tubing / trocar, a solenoid / valve fault, or a pressure-sensor fault.
Poor video image
HighSymptoms: Noisy, dark, discoloured or out-of-focus image, dropouts, no image.
Root cause: Camera head / coupler fault, a camera-cable fault, or a CCU / video-processor fault.
White-balance / colour fault
MediumSymptoms: Cannot white-balance, persistent colour cast.
Root cause: Camera head sensor drift, a dirty coupler, or the light source colour temperature.
Gas heater fault (if fitted)
LowSymptoms: Gas delivered cold, heater alarm.
Root cause: Heating element or its sensor in the heated tubing / unit.
Output / connector fault
LowSymptoms: Signal only on one output, connector damage, HD/SDI dropout.
Root cause: Worn video output connector or an output board fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Leak testing before each reprocessing cycle
- ·Scope reprocessing per AAMI ST91
- ·Light source lamp-hour tracking
- ·Annual full PM
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Will not hold set pressure
- Confirm the CO2 cylinder / supply is not empty and is at pressure.
- Leak-test the tubing set and all trocar / stopcock connections.
- Run the insufflator's self-test / calibration.
- Check the solenoid and pressure sensor per the service manual.
- Replace the tubing set; refer the valve block or sensor if the fault persists.
Symptom: Poor video image
- Clean and re-white-balance; inspect the scope lens / coupler.
- Swap the camera head and cable to isolate head vs CCU.
- Check the light cable and lamp hours.
- Try a second monitor / output cable.
- Replace the camera head or refer the CCU as isolated.
