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 of the need to create a Ventilator solution for the scarcity plaguing our society worldwide. I contacted Jeremias Almada from Argentina who by that time had presented an Ambu solution and a Cad Design. The idea was interesting but needed improvements.

Since then we tried to establish some development and community standards and evolved the project several times.

❗❗DISCLAIMER

PROJECT STATUS: We still need validation with health regulatory institutions and compliance with clinical requirements.

PLEASE DO NOT USE ONLY TIRE-CHAMBER, ENCASE THE the inner part of the TireChamber with a foodbag like ZIPLOCK or any material with compliance to contact with food.

⚠️ WE DO NOT YET GUARANTEE THE OPERATION OF THIS MACHINE | THIS MACHINE IS FOR EMERGENCY and HEALTH SYSTEM COLLAPSE SCENARIOS

Main Goal

Design, Build, Validate and Supply a reliable Ventilation Medical Equipment for people/regions/countries in difficult economical situations with a component- and mechanical-agnostic philosophy. (This is why we didn't continue putting efforts into the projects being developed by other teams, who have a different society and economic 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, Bellows 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.

The technical features are still being decided, the ventilator has not been validated yet.
