  1. Fluid/blood warmer for treating roadside trauma Submitted by Name: Mark McEwen, Anne-Louise Smith Affiliation: CED Collaborator National association (if exists): SMBE, Society of Medical & Biological Engineering Location: Adelaide, South Australia E-mail address for contact: anne-louise.smith@sa.gov.au

  2. Country Estimates in BriefPlease fill the statistics you can find Global CE / HTM Success Stories

  3. Country's Health Technology ProgramFluid/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. Global CE / HTM Success Stories

  4. Country's Health Technology ProgramNext 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 Global CE / HTM Success Stories

  5. 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 Global CE / HTM Success Stories
