Cincinnati Sub-Zero Blanketrol III
Cincinnati Sub-Zero · Model Blanketrol III
Preset-Variable and Programmable Variable Gradient temperature selection is available in both heating and cooling mode which allows for rapid or gradual patient temperature management control. A new feature, SMART mode, associated with the term gradient setting is to have the ability for the BIII to adjust the gradient temperature settings of 5°C should you not reach your desired patient temperature within 30 minutes. The Blanketrol III continues to monitor and adjust temperature every 30 minutes until your desired patient temperature is reached.
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.
Heater / element fault
MediumSymptoms: No heat, overheat alarm.
Root cause: Element or thermal fuse failure.
Temperature sensor drift
MediumSymptoms: Setpoint error, alarm.
Root cause: Sensor aging.
Fan / airflow failure
LowSymptoms: Uneven warming, hotspot.
Root cause: Blower wear.

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: Heater / element fault
- Confirm the presentation - typically no heat, overheat alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: element or thermal fuse 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 / thermal fuse 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.
Symptom: Fan / airflow failure
- Confirm the presentation - typically uneven warming, hotspot - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: blower wear.
- 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 blower fan 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.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Warnings statements have been added- exceeding 40 degree C for extended periods may cause tissue damage. Additionally, a caution was added and clarifications were made regarding the use of the Automatic modes
- RECALL
The incorrect voltage component was placed into the device during manufacturing. This may make the device unable to maintain patient temperature during cooling mode. The device will continue to indicate that the unit is cooling because the compressor will continue to run, however water in the reservoir will begin to return to ambient temperature. The actual water temperature will be displayed but
- RECALL
During a label review it was discovered that both the Blanketrol III Operations (57201-N) & Operations & Technical (56201-Q) manuals had verbiage added back into the manual during ECN M111-4260 (released 12/29/2011) which was previously removed for clarification of the intended use and subsequent 501(K) approval.
- RECALL
During a customer inquiry regarding a beta version of the Bill Data Export Software, Model USB-127, it was discovered that the wrong software version was released to a customer.
- RECALL
The suspect hyper-hypothermia device systems sold to physicians for research and/or the treatment of AIDS or Cancer patients, were not appropriately cleared by the FDA prior to distribution.
- RECALL
The firm initiated this recall due to changes that have been made to the Blanketrol III Model 233 device's Operation and Operation/Technical Service Manuals, in order to stay in compliance with labeling regulations.
