HemoTemp® II Blood Bag Indicators
Ensure Safe Blood Storage
HemoTemp® II indicators are advanced blood bag temperature indicators designed to monitor the time and temperature history of blood units. These liquid crystal temperature indicators provide both reversible and irreversible temperature monitoring, ensuring that blood storage conditions remain within the recommended safety range.
How HemoTemp® II Works
- Upon activation, the irreversible temperature indicator changes from blue to a non-blue color as the blood bag temperature increases over time.
- Once the blue color disappears, it does not revert—even if the blood unit is cooled again—ensuring an accurate record of temperature exposure.
- This feature helps blood banks and healthcare professionals track whether a blood unit has been stored within safe temperature conditions.
Why Choose HemoTemp® II for Blood Temperature Monitoring?
HemoTemp II indicators react to:
✔ Product temperature and time exposure
✔ Blood bag size/mass and heat transfer properties
✔ Real-time monitoring, similar to the blood bag’s sensitivity to temperature changes
Since these blood bag indicators attach to the outside of the blood unit, they provide a clear and visible status for easy monitoring by blood bank staff and hospital personnel. If a blood bag exceeds the recommended storage temperature, staff can take necessary actions to maintain blood quality and safety.
How to Read the HemoTemp® II Indicator
- TAN – Indicates a temperature in the lower portion of the range.
- GREEN – The blood bag temperature is within the acceptable mid-range.
- BLUE – The blood bag is in the higher portion of the temperature range.
- No visible numbers – The temperature is either above 9°C or below 1°C.
Note: HemoTemp® II indicators should be used as part of a comprehensive blood temperature monitoring program and not as the sole determinant of clinical acceptability.
