Medtronic HysteroLux
Medtronic · Model HysteroLux
Fluid management system for hysteroscopic procedures. With a touchscreen user interface, improved operation settings and rapid response to changes in intrauterine pressure, the HysteroLux™ system offers a next generation solution for hysteroscopic procedures. The HysteroLux™ system enables continuous, real-time monitoring of fluid deficit when its scale is in use. And it reduces the risk of fluid overload by continuously monitoring fluid volume deficit with ±6 percent accuracy.
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.
Intrauterine pressure not maintained or overshoots
HighSymptoms: Pressure sags or spikes vs the set point, poor distension, pressure alarms.
Root cause: Inflow peristaltic pump rollers, pressure transducer drift, or a tubing-set fault.
Fluid deficit inaccurate / scale fault
HighSymptoms: Deficit reads implausibly, jumps, or will not tare; outside the +/-6% spec.
Root cause: Weigh scale / load cell out of calibration, bags not hung freely, or a tare error.
Weak outflow / suction
MediumSymptoms: Poor clearance of the cavity, fluid backs up.
Root cause: Vacuum pump, canister seal, or outflow tubing occlusion.
Tubing-set / cassette recognition fault
MediumSymptoms: System will not recognise or prime the disposable set.
Root cause: Cassette mis-seated or a set-detect sensor fault.
Touchscreen / control fault
LowSymptoms: Unresponsive or erratic touchscreen.
Root cause: Display or controller fault.

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: Pressure will not hold at set point
- Fit a fresh tubing set and re-prime.
- Confirm inflow and outflow lines are not kinked or clamped.
- Check the inflow pump rollers for wear.
- Verify the pressure transducer against a reference if tooling allows.
- Replace the pump roller assembly or transducer as found.
Symptom: Fluid deficit reading looks wrong
- Confirm all inflow and outflow bags/canisters hang freely on the scale.
- Tare with the system at rest and no load change.
- Hang a known reference weight and confirm the reading.
- Recalibrate the scale per the service manual.
- Replace the load cell if it will not calibrate.
