We are current on the Stage of prototyping the MARK II version.

The Spartan Version has work well and we are trying to solve the problem on a global scale.

Several atempts to create a mechanical ventilator have been made in the last month all them not consideringthat 1.8Bi people live with less than 100 dollars a month. Fancy Solenoid Valves and Ambu-bags are not available in villages and country side towns in many places in the world.

To keep up with the project please join our github https://github.com/popsolutions/openventilator

This is how manifest:

OpenVentilator

Welcome to the OpenVentilator project. This is an OpenSource Ventilator / Mechanical Respirator for the Covid-19 Crisis.

This initiative as well as OpenLung was born on the Open Source COVID19 Medical Supplies Facebook Group by the awareness on creating a Ventilator solution for the scarcity plaguing our society world wide. I contacted Jeremias Almada from Argentina who by that time had presented an Ambu solution and a Cad Design. The idea was interseting but needed improvments

Since than we tryied to stablish some development and community standards and changed several times the project

Main Goal

Design, Build, Validate and Supply a reliable Ventilation Medical Equipment for people/regions/countries in dificult economical situations with a component and mechanical agnostic philosophy. (That's is why we didn't continued putting efforts on the projects being developed by other teams who have a different society and economical reality)

The equipment must have as few industrial parts as possible. If necessary, industrial parts must be easily accessible, even in small towns and villages.

The equipment should be built independent of the main motor or the ventilation tool (AmbuBag, Bellow etc) to increase modularity of the parts and resources

The equipment can be built with as few tools as possible, and even with the use of scrap to facilitate access to materials.

Thechnical features are still being decided, the ventilator has not being validated yet.

Risk Control

• PEEP Valve control between 1mm/h20 ~ 40mm/h20
• Mechanical Volumetric Ventilation Adjustment
• Contagion reduction by contaminated air
• Brazil Sanitary Regulations

Success Criteria

Validated Prototype (Looking for partners for testing on Lung Simulators)
