CoVent-19 Challenge

Building a rapidly deployable, minimum viable mechanical ventilator for patients with COVID-19 related ventilator-dependent lung injury.
Winner Announced



The CoVent-19 Challenge is an open innovation 8-week Grand Challenge for engineers, innovators, designers, and makers. We will be launching the Challenge on the GrabCAD Challenges platform on April 1, 2020. We welcome all who are interested to join a two round challenge that aims to create CAD assemblies by May 1, 2020 (Round 1: General Admission) and functional prototypes demonstrating acceptable performance by June 1, 2020 (Round 2: Invitation Only).

Participants will be allowed to submit multiple designs during Round 1, and participants may choose to submit full system designs and/or modules/parts for other teams to integrate into their design. Design briefs, system requirements, detailed team instructions and background information on mechanical ventilation will be provided when we launch on April 1, 2020. Round 2 will be invite-only and invited teams will receive access to additional resources for finalizing their design and creating functional prototypes.

  • Launch: April 1, 2020
  • Round 1 (Open Entry): April 1, 2020 – May 1, 2020
    (The deadline for joining Round 1 is the submission deadline on May 1, 2020)
  • Round 2 (Invite Only Round): May 5-27, 2020
    (Teams will be invited to Round 2 by May 4, 2020)
  • Winning Design Announced: June 1, 2020

Anticipating the unmet need for mechanical ventilation to treat infected individuals with lung infection from COVID-19 is crucial to their battle with this virus and survival. The United States has the capacity to ventilate about 170,000 patients, while 960,000 patients are projected to require mechanical ventilators. Even with the addition of a hundred thousand more mechanical ventilators, we do not have the capacity to ventilate this many patients, forcing physicians to make the impossible decision— who receives mechanical ventilation to continue to fight COVID-19 and who will not. How might we increase the capacity of hospitals to provide mechanical ventilation to those infected?

Our answer will be rapidly deployable ventilators that we can use to close the gap between those in need and our actual resources in healthcare systems around the world.

CoVent-19 Challenge is an open innovation challenge to develop rapidly deployable solutions for the COVID-19 mechanical ventilator crisis. The Challenge will consist of a 2-round design challenge that aims to finalize CAD assemblies by May 1, 2020 and functional prototypes by May 27, 2020. CoVent-19 has convened panels of medical and technical experts who will guide requirements and design processes.

The general entry round, focused on initial designs, will run for four weeks, with a panel of judges selecting up to 20 finalists. Evaluation by judges of minimum-viable ventilator designs will assess safety, reliability, and manufacturability, while minimizing cost and complex software and electronics.

Finalist teams will work with medical and technical experts through a four-week invitation-only round to develop and test functional prototypes. Stratasys application engineers will provide 3D printing consulting and services to the finalists.

To ensure our ventilator solutions reach the infected people in need, we have partnered with manufacturing and global health experts who have experience in navigating world-wide crises.

How will the ventilator reach the people in need?

The CoVent-19 Challenge offers participants an unbeatable platform of resources to streamline the winning design through prototyping, safety and regulatory testing, manufacturing and distribution. Our partners have experience in manufacturing medical devices and navigating world-wide crises.

World-class leaders in respiratory physiology, critical care, and ventilator technology will form our expert medical and technical panels.  They will provide guidance to teams on the safety, clinical, and technical requirements.  Stratasys, the world leader in 3D manufacturing and prototyping, will co-host the design process and prototyping of designs.   Ximedica, with more than 30 years of expertise in medical device design and manufacturing, will align with regulatory agencies to take the winning device through the necessary safety and regulatory testing, thus ensuring compliance with national and international standards.  We are currently in discussions with manufacturers, distributors and the public sector to deliver the final winning ventilator around the world.

How will the CoVent-19 Challenge team support participants through the process?

Stratasys, GrabCAD and Valispace, are providing our participants free software for this challenge.

GrabCAD Workbench and GrabCAD Print offer cloud-based tools to collaborate on draft CAD designs that can be seamlessly 3D printed through our sponsor, Stratasys. During Round 2, invited teams will be supported with free rapid prototyping assistance.

Participants are also encouraged to work at a physical distance over Valispace. This software offers teams a platform to collaborate on requirements-driven hardware designs remotely, organize, and grow their projects throughout the creative process.

Participants will have access to GrabCAD Forums where they can send questions to our clinical and technical expert panels, including expert physicians on the frontlines of the COVID-19 pandemic and ventilatilator industry experts.


What sparked our initiative?

The first cases of COVID-19 in the United States hit close to home.  We saw issues other countries were struggling with, including the inability to provide invasive mechanical ventilation to all those in need.  As anesthesia doctors, we are experts at using ventilators to care for critically ill patients, and thus felt an immediate calling.

Why is mechanical ventilation so vital to surviving COVID-19?

COVID-19 can cause severe pneumonia (or lung infection).  When the infection is severe, the effort of breathing increases, making it difficult to supply oxygen to vital organs.  Patients may require extra breathing support from a mechanical ventilator, a machine that takes over the effort of breathing so that the lungs have time to heal.

How is your strategy different from large companies ramping up production of mechanical ventilators?

Although ramping up production will help address the deficit in mechanical ventilators around the world, the speed and severity of the COVID-19 pandemic require urgent solutions that be deployed globally, including in low-resource areas where standard mechanical ventilators may be challenging to obtain.  We aim to augment our existing resources in a rapid and fluid way that enables us to expand and contract our resources to match the clinical needs around the world.

How will increasing our current mechanical ventilation capacity impact the COVID-19 pandemic?

Each country has its own projected pandemic peak.  The CDC is predicting a peak in late April to May in the United States.  According to the Society of Critical Care Medicine, the United States has the capacity to ventilate about 170,000 patients at one time, while 960,000 patients are projected to require mechanical ventilators.  Even with the addition of a hundred thousand mechanical ventilators, we may not have the capacity to ventilate all those in need, forcing physicians to make the difficult decision–who receives mechanical ventilation to continue to fight COVID-19 and who will not.
