There are a few main different styles of fluid warmers:
In-line: Room temperature (or colder) fluid flows through a device that heats it up as it passes through.
- Easiest to use, no preheating of IV bag required.
- Smallest footprint.
- Consistent temperature delivered.
- Likely harder to assemble. May have more individual parts to source.
- Most sophisticated and challenging to design and test.
Surface Heater: The IV bag sits on a warming surface that maintains the desired temperature.
- Simplest design, likely easiest to 3D print and assemble.
- Easy to verify correct operation.
- Once an IV bag is removed the temperature gradually drops as fluid is being administered.
- Larger footprint.
Oven: Fully enclosed unit that heats through ambient air.
- Easy to self-monitor
- Easier to scale up for more bags heating at once.
- Once an IV bag is removed the temperature gradually drop as fluid is being administered.
- Largest footprint.
