Pentax EG-1840
Pentax · Model EG-1840
Video Gastroscope The Pentax 40 Series Endoscopes feature "fully brushable" internal channels. With the Pentax original detachable distal cap, this series offers the ability to remove the distal air/water and water jet nozzles to pass a cleaning brush through each internal channel. All lumen surfaces - including the air/water, biopsy/suction and water jet systems - are completely accessible for mechanical cleaning with brushes. With infection control and proper reprocessing always an issue, this series maximizes the decontamination process and minimizes the need to service clogged channels. Channel Diameter 2.0mm Insertion Tube Diameter 6.0mm Working Length 1050mm) Angulation Up/Down Right/Left 210/120 120/120 Angle of View 120°.
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.
Fails the leak test
HighSymptoms: The manual or automated leak test fails; bubbles from the bending section, insertion tube, or a channel port.
Root cause: A pinhole in the bending-rubber, a channel breach, or a damaged distal cap - fluid invasion risk.
Poor or lost image
HighSymptoms: Blurred, dark, spotty, half-image or no image; colour cast that will not white-balance.
Root cause: Fluid invasion into the CCD / fibre bundle, a broken image bundle, or lens-surface damage / adhesive fog.
Angulation / bending-section fault
MediumSymptoms: Up/down or left/right angulation is loose, will not hold, over-tight, or limited range.
Root cause: Stretched or broken angulation wires, a worn brake, or bending-section damage.
Channel blockage / air-water or suction fault
MediumSymptoms: Poor suction, no or weak air / water, will not pass a cleaning brush.
Root cause: Debris or a kink in the channel, a worn air/water or suction valve seat, or a crushed channel.
Light-guide / connector fault
MediumSymptoms: Dim or no illumination from the scope with a known-good light source.
Root cause: Broken light-guide fibres or a damaged light-guide connector.

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: Fails the leak test
- Repeat the leak test, watching where bubbles originate (bending section, insertion tube, channels).
- Confirm the leak tester / connector itself holds pressure.
- Quarantine the scope immediately - do not reprocess a leaking scope in fluid.
- Send for channel / bending-section repair.
- Re-leak-test and re-image after repair before returning to service.
Symptom: Poor or lost image
- Confirm the processor, light source and monitor with a known-good scope.
- Inspect the distal lens for scratches, chips or adhesive fog.
- Check for fluid droplets behind the lens (invasion).
- White-balance and check all channels.
- Send for image-bundle / CCD repair if the fault is in the scope.
