FutureMed ASTOTHERM PLUS
FutureMed · Model ASTOTHERM PLUS
Fast, easy setup, requiring no special priming. Astotherm Plus warms up in less than a minute. A visual temperature display lets you monitor fluid temperature. Astotherm Plus has 3 independent safety alarms and a circuit shut-off to eliminate the risk of overheated fluid reaching the patient. The economical Astotube extension set costs significantly less than disposable sets required for other fluid warmer, making it practical to provide the benefits of warmed fluids to more patients while savings hundreds or thousands of dollars each year. Astotherm Plus can be disconnected from the IV line without interrupting the flow of fluids to the patient. Astotherm's dry-heat surface is mess-free and can be wiped clean in seconds.
Key tips
- ·Never skip temperature-accuracy verification to save time - it's the one check that directly prevents burns.
- ·Hose/blanket connector wear is the most common real fault and the easiest to miss on a quick visual check.
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.
Fluid / blood not reaching target temperature
HighSymptoms: Output below target, low-temperature alarm, slow warm-up.
Root cause: Heater plate(s) or the heater-control circuit, or a temperature-sensor fault.
Over-temperature alarm / shutdown
HighSymptoms: The unit disables heating with an over-temperature condition (protects against haemolysis).
Root cause: Sensor or control fault driving the heater high, or an extreme flow-rate change.
Air-detector / bubble-trap alarm (rapid infusers)
MediumSymptoms: Air-in-line alarm, flow stops.
Root cause: Air in the set, an improperly primed set, or an air-detector fault.
Disposable-set detection / fitting fault
MediumSymptoms: Set not detected, will not clamp / seat, leaks at the warming chamber.
Root cause: Worn set-detection switch or chamber fitting.
Flow / pressure fault (rapid infusers)
MediumSymptoms: Cannot reach set flow, pressure alarm.
Root cause: Pump / roller fault or an occlusion.

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.
- ·Hose / blanket connector inspection
- ·Temperature-accuracy verification
- ·Annual electrical safety test
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: Fluid / blood / blanket not reaching target temperature
- Confirm the correct programme / set for the fluid type and flow rate.
- Check both heater plates (or the water bath) warm evenly.
- Verify the output temperature against an independent reference at a representative flow.
- Replace the temperature sensor if it disagrees.
- Replace the heater plate / control assembly if output is still low.
Symptom: Over-temperature alarm / shutdown
- Let the unit cool and restart.
- Compare the displayed temperature to an independent reference.
- Check for an extreme flow-rate change during use (fluid warmers).
- Replace the temperature sensor / control board as isolated.
- Confirm stable control across the range before returning to service.
Symptom: Low airflow / blower fault (forced-air) or low water flow (water blanket)
- Replace the intake / HEPA filter (forced-air) or top up and de-air the reservoir (water).
- Check the hose for kinks or splits and confirm the correct blanket type.
- Inspect the blower / circulation pump and impeller.
- Replace the blower / pump if flow is still low.
- Confirm delivered air / water temperature and flow after repair.
