3. Global CE / HTM Success Stories
Country's Health Technology Program Fluid/blood warmer for roadside trauma
Retrieval patients are often in shock, hypotensive and hypothermic (<37ºC). Treatment requires rapid restoration of blood volume with transfusion of donor blood and/or clear fluids.
The Transfusion Service clinicians determined there was a need for trauma/retrieval patients to receive these fluids at close to body temperature to reduce the risk of hypothermia.
There is approximately 0.51ºC temperature drop per litre of 4ºC fluid infused into a 70 kg patient starting at 37ºC
No devices could be found to meet the need so a device was developed by Biomedical Engineering.

4. Country's Health Technology Program Next Steps for Success Story
The Intravenous Fluid/Blood Warmer was developed
Uses latent heat of fusion as an energy source.
Initial validation was performed to ensure heating is adequate for infusion whilst non injurious to red cell products (results published BMC Emergency Medicine)
Useful requirements
Blood: Warm at least 2 units from 4ºC to >30ºC at flow rate of 50 mL/min with single device
Gelofusine (fluid): Warm at least 1L from 20ºC to >30ºC at flow rate of 150 mL/min with single device
Device: Convenient size, weight and volume No external power source required, stable over range of temperatures, long life, reliable and fast acting heat
