Smiths Medical Level 1 H-1200
Smiths Medical · Model Level 1 H-1200
• Rigid pressure chambers accommodate standard blood and crystalloid bags providing a constant 300mmHg pressure for rapid infusion • On/Off toggle switch used to quickly and easily pressurize chambers • Aluminum heat exchanger, that transfers heat 1000 times faster than plastic, and the counter current 42°C circulating water bath, ensure patients receive normothermic blood and I.V. fluids • Additional level of safety with the integrated Air Detector/Clamp that detects the presence of air in blood and crystalloid, alerts clinicians, and automatically stops the flow and allows quick removal of air without disconnecting from the patient or changing disposables.
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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Heating element / cartridge fault
HighSymptoms: No heat, or overheat alarm.
Root cause: Heater element or thermal cutoff failure.
Temperature sensor drift
MediumSymptoms: Delivered fluid temperature out of set range.
Root cause: Inline/probe sensor aging or miscalibration.
Air-in-line detector fault
HighSymptoms: False or missed air-in-line alerts.
Root cause: Air detector sensor drift or dirty optics.
Disposable tubing set leak / seating fault
MediumSymptoms: Fluid leak, or won't prime.
Root cause: Worn cassette/tubing seat or cracked fitting.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Heating element / cartridge fault
- Confirm the presentation - typically no heat, or overheat alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: heater element or thermal cutoff failure.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the heating element / plate per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
