Stryker AHTO
Stryker · Model AHTO
Cordless console alleviates clutter in the OR. Tubing offered with disposable or reusable tip attachments. Self-priming system. Instant activation upon insertion of cassette tube sets. Simple installation and disposal improves OR efficiency.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
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.
Distension pressure not maintained or overshoots
HighSymptoms: Set pressure sags or spikes, poor distension, pressure alarms.
Root cause: Inflow pump rollers, a pressure-sensor fault, or a tubing-set fault.
Fluid-deficit / weigh-scale fault (FluidSafe)
HighSymptoms: Deficit reads implausibly or will not tare, alarm at the wrong volume.
Root cause: Weigh scale / load cell out of calibration, or bags not hung freely.
Weak outflow / suction
MediumSymptoms: Poor clearance of the cavity, fluid backs up.
Root cause: Vacuum / outflow pump, canister seal, or tubing occlusion.
Tubing-set / cassette recognition fault
MediumSymptoms: System will not prime or recognise the disposable set.
Root cause: Cassette mis-seated or a set-detect sensor 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.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
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.
- 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.
