Who are we? 

TeamOSV was started in March 2020 in response to the COVID-19 global pandemic. Our vision was to build a team to design and develop an Emergency Field Ventilator (EFV), initially under the name Open Source Ventilator Ireland. In response to increasing needs and shortages, TeamOSV expanded and adapted. TeamOSV now stands at over 3,000 volunteers working on not only the EFV but also over 40 more open-source solutions related to COVID-19.

These projects span from low-tech DIY and 3D printed face shields to high-tech thermal cameras. They also include societal movements including the processing, collection and delivery of crucial PPE for front-line staff. TeamOSV is now a multidisciplinary team of engineers, designers, makers, and medical practitioners working on developing novel low-resource interventions through online collaboration. 

Our goal is to connect ambitious volunteers, teams and organisation in the fight to produce open-source solutions to Covid-19 related issues. 


OSV Ireland was formed by Colin Keogh, Conall Laverty and David Pollard as an Irish response to Covid-19 inspired by the many Opensource Facebook Groups that were established in March 2020. In a matter of hours, a core team of volunteers assembled to start rapidly building an open-source intervention to develop emergency field ventilators. Over a matter of days, the world took notice of our efforts, and a huge volume of amazing volunteers signed up to join TeamOSV and the fight against Covid-19. 

It quickly became clear that not just Ventilators would be needed, but also a range of other concepts including PPE, Face Shields, Tracking Apps, Educational Guides and other solutions. OSVX was spun out of OSV by Gillian Berry and Róisín Lyons, who led the collection, structuring and identification of requirements from frontline staff. This group has been leading the way in open source innovation facilitating a huge amount of impact with a number of partners around Ireland.
