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.

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

Conclusions and Action Plan
• Clinical trial in progress
– Patients receiving planned blood transfusions
– No adverse effect on patients or blood test results
• Useability trial
– Emergency Department & Intensive Care Unit nurses using
the warmer, to determine the best operating method and most
effective instructions
• Commercialisation
– The device has been
licensed to a
specialist plastics
fabricator, partnering
with an IV set
manufacturer
– Production scheduled
when trials completed
