The Open-Source Design Movement fighting Covid-19




Welcome to #TeamOSV, the home for the design and development of rapid open-source solutions to real-life problems. 

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. 

We have a core developer team publishing open source designs with ongoing communication with medical professionals regarding needs requirements, testing and validation processes.

Our Projects

The problems posed by COVID-19 are varied, but information shows that the main issues are an urgent need for equipment, materials and support in treating this disease. 

During this time, the availability of respiratory support, ventilators, PPE and other technologies are required. Healthcare systems may be overwhelmed by these requirements, thus leading to shortages. This could be a significant issue in developing regions with less robust healthcare systems. 

We hope that our solutions will never be required and never be used in practice, however, if they are needed, we would like to have a range of prototyped, tested and medically validated solutions ready for emergency use globally. This group was established to utilize the public hive mind and the creativity of our volunteers to build an truely Open Source response to real-world emergency situations.

Project Philosophy

This project is truly Open-source in nature, with solutions developed for use worldwide and open from contributions from others.

  • Open source in nature so iterative and open for community involvement
  • Development of a Field Emergency Ventilator (FEV) to support medical practitioners
  • Development of other Frontline care requirements such as PPE, Applications and other medical tools.
  • Safety is paramount. These concepts are designed to reduce harm and risk of death. No potentially unsafe devices will be shared. Medical validation is a priority.
  • Supplies and materials will be locally sourced where available
  • The design(s) will be validated; validation will be documented and transparency will be made available to local health service.
  • Dissemination via Internet ( and GitLab.

Operational Assumptions

  • Regulatory bodies may waive clearance or reduce regulatory barriers for emergency interventions.
  • Traditional certified medical components and supplies used in ventilators will be in short supply.
  • Logistics will be impaired/disrupted. Non-medical supplies, manufacturing systems and components will be readily available globally.
