What do we currently need?
Our project depends on your solidarity
This project from the beginning was based on solidarity, we have the support of friends, companies, neighbors, family members, co-workers. We have reached a point where it is necessary to expand the initial idea, to accelerate the development and scale of the project. We must do it this way in view of the PANDEMIC situation of society.
Our team has members on 5 continents and in more than 20 countries. We are already giving our most precious resource, which is our time and our knowledge, but time and knowledge only bring wisdom, not solutions, and we currently need a medical solution in respirators / ventilators.
We need to carry out medical / clinical tests, so we intend to purchase buy (you can also donate these materials if you have them) - If you have medical facilities willing to help please contact us on the GreenLink Bello
Oxygen Sensors (for clinical validation of the O² mixture)
Pressure sensors (for validation, not for the device itself)
Flow Sensors (also for validation)
Raw Material and Tools for the MarkII Version
Acrylics (6mm and 3mm sheets)
Windshield Wiper Motors
CNC Laser Cutting Machine
Filament printing material (Petg / PLA)
If you can donate these materials please contact us directly here! DONATE MATERIAL
This was the first prototype of OpenVentilator
This project never got off the ground. But this was only possible because many donated their work time, effort and mainly material to prove that this model would not move.
The Open Source Respirator or Ventilator Project, as you want to call it, is a project that emerged on March 9, 2020, ten days before the initial initiative to join forces with a team.
Our first intuition was that Pandemic would spread quickly not only in our country of origin but also in the world. The only idea that could be scaled to the pace of the pandemic was an Open Source ventilator project.
On March 19, we contacted Jeremias Almada, who had presented some sketches of an "Ambu Pusher" project in a Facebook group CoronaVirus Rapid Supplies.
More Spartan prototypes v.0.0.2
We eliminated the movement of the lever, developed our own diversion valve with 3D printer. We made a system with greater volumetric control and mainly precision. The real Spartan model begins to emerge. Our expenses are already starting to be a big part of the problem to develop the prototypes. It was with this v.0.0.2 that we made the first tests in a simulator.
We started to see the first results, but adjustments are still needed. We make available the first plans for reproduction attempts to happen worldwide in order to streamline prototyping and minimize errors
Although still very homemade, the respirator is placed in a pulmonary simulation device, kindly provided by Samtronic, a company specialized in the validation of respirators and similar equipment.
We passed the first tests
The device used as a simulator is a Michigan Instruments, which was used together with the prototype to simulate various types of complacency and volumetry. As well as maximum pressure curves. To learn more about the results SEE THE TESTS
The project undergoes changes in terms of security and structure
Allocation of the diversion valve within the equipment and away from the patient
Improvements in volumetric adjustment tables and scales
Equipment assembly documentation improvements
Validation of test results with Pulmonologists and Intensivists
Increased rigidity and durability of the equipment structure
Bellows system improvements
Improvments on the Gantry system
The last version so far
So far the best and most reproducible emergency ventilator/respirator
Valves specially allocated for easy maintenance. Acrylic or stainless steel structure. Reliable and robust. A truly warrior and spartan system
