The Oxygen and Ventilator System Initiative (OVSI) is an international collaboration that seeks to advance and influence affordable, life-saving oxygen treatments.Our Approach
The OVSI team would like to extend its heartfelt (not to mention lungfelt) thanks to Arkema for supplying another drum of Zeolite. This has come at a crucial time for the project because supplies from the previous shipment were running low, and if these had been exhausted it would have stopped the vital prototype testing that is now going ahead in Bahir Dar and Cambridge.Read more
The OVSI Oxygen Concentrator produces almost pure oxygen from the air readily available around us. It eliminates the need for pressurised oxygen canisters and complicated hospital supply lines, reducing the need for trained personnel and enhancing overall safety.Learn More
The OVSI Ventilator is designed for a range of uses required in intensive care units. It works both with and without intubation – it is easy to adjust its settings either way. The ventilator design has been made available through Open Source.Learn More
Great things happen when a good team comes together. After working 3500 miles apart for so long, the OVSI oxygen concentrator engineering teams from the UK and Ethiopia finally had the opportunity to work together physically, and the results were really encouraging.
The team in Bahir Dar has been making excellent progress throughout the Spring months. The design and milling for the PCB board that will integrate with the Arduino Mega and run the sensors, valves, displays, LEDs and power supply is almost complete, and a prototype frame structure has been designed, printed and machined using SOLIDWORKS. The design and manufacture of a sound proof box that will be used to house the Concentrator prototype has also been finalised.
The OVSI team led an exciting online seminar as part of the Cambridge Festival. Attendees were treated to interviews with Kobus Preller, an intensivist at Addenbrooke's Hospital and clinical advisor to OVSI, and with Mark Fryer of Cambridge Compressors, one of OVSI’s industrial partners. We also got a peek into the facilities and faces behind the Bahir Dar Institute of Technology (BiT) with a video put together using footage filmed during the Cambridge team’s visit to Bahir Dar in March.
