Fluid warmers are important devices in medical facilities, but they can be difficult to get in developing areas. There is a high cost for this equipment (often thousands of dollars), and it can take a long time to obtain or replace. We’ve also seen that global issues like COVID-19 can cause serious supply chain issues on custom equipment.

The solution to these two hurdles would be a completely open source device that can be assembled by nearly anyone with easy to obtain and standard components. Any custom parts would ideally be 3D printed. This would allow the device to be largely built and assembled in the country it is to be used in. The device should be easy to assemble, without requiring any special skills or advanced tools (soldering, PCB production).

Aesthetics, user interface, and features will likely be simple in order to best accomplish the above requirements.

To reiterate, the most important metrics would be:

• -low cost
• -ease of component sourcing and manufacturing
• -short lead time
• -accurate and reliable temperature monitoring and regulation
