ProjectApollo

This Github repository contains Designs/docs/software/PCB for Project Apollo (open source oxygen concentrator)

For more context behind the history/goals/motivation for this project please see our coverage in Helpful Engineering blog:

Update: check out our presentation at RespiCon 2021!

Apollo v2 build instructions

Why

  • Ventilators need oxygen! (typical FiO2 0.4 … 0.9)
  • Oxygen generation is a big problem in developing countries.
    • No established infrastructure.
    • Oxygen bottles are expensive
  • People are already looking at alternative (local) ways for producing oxygen

What

  • Goal of the Apollo prototype = enabling people around the world to build the prototype as fast as possible
  • Focus = Simplicity and speed of build
  • Final goal = Enable people to iterate and publish their own designs in the community

How

  • Follow the published build documentation
  • Buy/source the materials (check out the BOM)
  • Build the prototype
  • Validate O2 concentration and flow. Use a good O2 and flow sensor.
  • Think about risk analysis and assessment: template for Apollo-derived design
  • Document and iterate your own design. Publish your findings to the community!

Target

  • Output medical grade Oxygen ideally at 93%
  • Flow rate of 1-20 liters per minute (5 l/m being standard for oxygen therapy)
