VUB engineers tackle imminent shortage of ventilation equipment

VUB engineers tackle imminent shortage of ventilation equipment

Prototype is ready and being tested

If the number of covid-19 patients in Belgium continues to rise, there may be a shortage of artificial respirators. A team of engineers at Vrije Universiteit Brussel’s FabLab Brussels has therefore started building and testing a simple ventilator. They started from a design by MIT, extended with sensors based on specifications from researchers at Johns Hopkins University and the UZ Brussel. Large-scale production is still premature. In the coming days and weeks, it will first have to be established whether the devices can actually be used in hospitals.

The engineers, led by Mark Runacres, professor of fluid mechanics and head of the FabLab Brussels, have adapted the design to the needs of covid-19 patients. In just a few days, they built a first prototype. “Speed is of great importance now,” explains Runacres. “Doctors on the front line don’t have time to exchange loose ideas with engineers. The FabLab team has therefore chosen not to talk but to build. Based on a working prototype, it is much quicker to decide whether the design is suitable for use in hospitals.”

The prototype was built in the FabLab Brussels by a team of staff, PhD students and students from VUB’s  engineering technology programme. They are part of a national and international network and are in direct contact with colleagues from academia and industry, who provide continuous feedback on the design and make suggestions for improvement. “That input is essential. Some companies have also made components available. In normal times they would probably be a bit reluctant, but now there is an awareness everywhere of the need to work together,” says Runacres.

The initiative fits in with the open-source philosophy that characterises the FabLab Brussels: if the prototype is found to be suitable, the plans for the design will be made publicly available, so that other labs can manufacture and improve the design. But in order to produce the volumes that may be needed, the FabLab needs support from industry. The response so far has been very positive.

About Press - Vrije Universiteit Brussel

Vrije Universiteit Brussel is an internationally oriented university in Brussels, the heart of Europe. By providing excellent research and education on a human scale, VUB wants to make an active and committed contribution to a better society.

The World Needs You

The Vrije Universiteit Brussel assumes its scientific and social responsibility with love and decisiveness. That’s why VUB launched the platform De Wereld Heeft Je Nodig – The World Needs You, which brings together ideas and actions based on six Ps. The first P stands for People, because that’s what it’s all about: giving people equal opportunities, prosperity, welfare, respect. Peace is about fighting injustice, big and small, in the world. Prosperity combats poverty and inequality. Planet stands for actions on biodiversity, climate, air quality, animal rights... With Partnership, VUB is looking for joint actions to make the world a better place. The sixth and last P is for Poincaré, the French philosopher Henri Poincaré, from whom VUB derives its motto that thinking should submit to nothing except the facts themselves. VUB is an ‘urban engaged university’, strongly anchored in Brussels and Europe and working according to the principles of free research.
