A COVID-19 breakthrough using $2 of 3D-printed plastic? These volunteers made it happen

TORONTO // MAY 7, 2020  — A volunteer team of 3D printer enthusiasts have made a vital contribution in the fight against COVID-19, helping to bring to reality an original design for a connector that enables a life-saving ventilator to be safely shared between multiple patients. Working with the research team at Toronto’s University Health Network, the results have been published this week in Critical Care Explorations, a peer-reviewed journal. The open-source design has been made available for 3D printing worldwide. 

Working at the Toronto Tool Library Makerspace near Queen and Spadina, the volunteers have also developed and delivered hundreds of protective face shields and mask tension relief bands to support front-line health workers.

The ventilator connector, fabricated from a 3D-printed connector part and a jar from Dollarama, went through more than 100 hours of thorough testing at UHN to ensure it meets hospital standards for safety and durability. The innovation went from idea to final design over a weekend, then thorough testing and into real-life use in less than two weeks — a process that normally takes 18 months. It’s a testament to the team’s dedication and to the need for rapid response in this unprecedented time. 

The team has formed a larger group working on production of PPE for senior home facilities and support workers. They continue to develop other essential devices that are currently in shortage and may be used in response to COVID-19.
