The BLOOD/FLUID WARMER (Biegler BW-685S) is inadequate for rapid and massive transfusions in trauma and maternal haemorrhage.Hypothermia constitutes one of lethal triad in trauma management and massive transfusion.

The Ranger Fluid Warming unit is capable of administering warmed IV fluid and blood at a very rapid rate (30,000 mL/hr). Current mortality analysis indicates that normothermia is not adequately maintained in these critical situations with standard catalogue items.


A mains electricity (AC-powered) device designed for heating of blood products or intravenous (IV) solutions, typically from about 4ºC to near body temperature (i.e. 35 to 40 ºC) before infusion, through the conduction of heat.

The device includes a surface heat exchanger for the conduction of heat to the infusion blood/fluid via a disposable tubing set.

The warmer is used to minimize adverse thermal reactions in the patient.

It is mounted with a clamp on an infusion stand under the infusion bag or on a normed rail. It does not infuse blood/fluid.

Precautions for Use

The length of the tube between the device and the patient must be at least 40 cm, and the tube must not be stretched.

The ambient operating temperature must be in the range of 10° – 30 °C.


Cleaning and disinfection:

  • Use a soft cloth with a water-soluble, non-aggressive cleaning agent or a special cleaning agent for plastics
  • For disinfection, only use a 0.25 % detergent-disinfectant solution for sufaces (i.e. 20 ml = 1 sachet = 1 stroke of dosing pump for 8 litres water)
  • Do not disinfect the device with steam (i.e. in autoclaves), hot air or thermochemical cleaning solutions

Periodic inspections:

Must be carried out at least every 12 months

  • checking the warm-up period
  • checking the control temperature
  • checking the low temperature information signal
  • checking the high temperature alarm
  • visual check of general condition
  • electrical safety
  • visual check of general condition (TubeFlow)
  • checking the control temperature (TubeFlow)
  • Over temperature control (TubeFlow)

Refer to the user manual for more details on how to carry out the checks mentioned above.
