Cobe Brat 2
Cobe · Model Brat 2
Dedicated processing keys to start processing quickly and easily. Built-in reservoir holder eliminates the need for additional holder. Flat, clear lid with safety lock provides visibility of the bowl and a flat writing surface. Smaller profile fits well in any size operating room. Storage area for additional supplies. Three position wheel locking mechanism maximizes mobility. Easy to load disposables snap correctly into place without hassle. Automatic re-pack feature removes excessive plasma free hemoglobin and ensures proper bowl filling. Patented Baylor Bowl provides a high hematocrit and fast processing.
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.
Roller / centrifugal pump fault
HighSymptoms: A pump will not run at set flow, speed unstable, occlusion out of adjustment, flow-probe error.
Root cause: Worn roller-pump raceway / rollers, a centrifugal drive-motor / coupling fault, or a flow-probe fault.
Console / control-module fault
HighSymptoms: A pump module unresponsive, display errors, module not recognised by the console.
Root cause: Module electronics or the console-to-module link.
Battery / UPS fault
HighSymptoms: Short back-up run time, will not transfer cleanly on a power interruption.
Root cause: Aged battery / UPS pack.
Pressure / level / bubble-monitoring fault
MediumSymptoms: Pressure, reservoir-level or bubble-detector alarms implausible or not triggering.
Root cause: Transducer, level-sensor, or bubble-detector fault.
Heater-cooler / temperature fault
MediumSymptoms: Blood / cardioplegia temperature not tracking, heater-cooler alarm, flow fault.
Root cause: Heater-cooler pump / refrigeration or a temperature-probe 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: A pump will not run correctly
- Move the function to a spare pump module / mast position to isolate module vs console.
- Check the roller occlusion setting and inspect the raceway / rollers (roller pumps).
- Check the centrifugal drive coupling and flow probe.
- Verify flow against an independent flow probe.
- Replace the roller kit or drive components as isolated; a CPB console must pass a full functional check before clinical use.
Symptom: Monitoring alarm implausible or not triggering
- Verify each pressure channel against a reference.
- Test the level and bubble detectors per the service procedure.
- Reseat the sensor connectors.
- Calibrate the pressure channels.
- Replace a sensor that fails its functional test - these are safety systems.
