Fujinon EG-250WR5
Fujinon · Model EG-250WR5
EG-250WR5 combines high resolution imaging - a 410K-pixel CCD is contained within the narrow distal end - with an ultra-wide 140 ° field of view to produce images of outstanding accuracy and detail. It allows better observation of minute blood vessels as well as excellent imaging in routine examinations. The slimmer 9.4mm diameter eases insertion and facilitates more extreme angulation. The channel has a 2.8mm diameter.
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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Insertion tube / bending wear
HighSymptoms: Stiff angulation, image artifacts.
Root cause: Repeat flexing / reprocessing.
Leak (water ingress)
HighSymptoms: Fogging, failed leak test.
Root cause: Damaged outer sheath.
Image sensor / CCD fault
HighSymptoms: No/poor image, color error.
Root cause: Sensor or cable failure.
Channel blockage
MediumSymptoms: Poor suction / irrigation.
Root cause: Debris in working channel.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Insertion tube / bending wear
- Confirm the presentation - typically stiff angulation, image artifacts - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: repeat flexing / reprocessing.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the angulation cable / mesh per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
