COVID-19 Response

3D Printing Ventilator Adapter

This project was initiated because of the possible shortage of medical ventilators during the COVID-19 pandemic. Several studies have shown that a single ventilator could be used for multiple patients simultaneously to meet disaster surge. We designed these ventilator adapters and used 3D printers to create them.

This project is not conducted to make a profit. We hope our hospitals never will need to have multiple patients share a single ventilator, but we must prepare for the worst. 

This webpage serves two purposes: To share the adapter designs, and to share the demand and supply information. Please contact us if:

  • You have a 3D printer and are willing to help with production.
  • You work in a hospital and need adapters.
  • You would like to contribute your design.
