Terumo Sarns 8000
Terumo · Model Sarns 8000
Modular design Four or five pump base Roller or centrifugal pumps Arterial and cardioplegia monitors for temperature, pressures and timers Battery module Electronic venous occluder Pulse mode Communications module for data acquisition.
Key tips
- ·Never defeat or bypass a return-electrode monitoring (REM) alarm to finish a case - it's a direct burn risk.
- ·Verify OR table battery backup - a table that loses power mid-procedure is a real, documented incident type.
- ·Track surgical light lamp-hours rather than waiting for failure - a sudden failure mid-case is avoidable.
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.

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.
- ·Pre-case functional check
- ·Electrosurgical return-electrode cable inspection
- ·Table hydraulic / mechanical inspection
- ·Annual electrical safety test and 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: 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.

Terumo Cardiovascular Systems (Terumo CVS) received complaints from our Affiliate, Terumo Dubai that the safety monitors were tripping off. Terumo CVS' investigation determined that 8 monitors were manufactured with an underrated circuit breaker due to an error where an associate pulled an underrated circuit breaker from an incorrect inventory location. Since this time, inventory locations hav
- RECALL
False Alarms: The air sensor may malfunction and trigger false alarms, and may continue to alarm thus preventing the device from being reset.
- RECALL
The hand crank may crack in the bearing/shaft area due to a manufacturing defect. (Note: Some of the hand cranks subject to this recall were shipped as replacements for hand cranks recalled in the Summer of 2006.)
- RECALL
Roller Pump: Due to a circuit board malfunction the roller pumps may stop during use without displaying an error message, may stop during use with an overspeed error posted on the local display, or may fail to start/restart resulting in the pump(s) being non-functional.
