OpenVent - 3D printable measurement tubes

thingiverse

During the Corona (COVID-19) pandemic it became obvious that a lack of medical equipment can cause a severe impact. Often, also simple equipment and designs can be helpful as long as no professional equipment is available. This repository contains generic information about <strong>an open-source ventilator device</strong>. Main purpose of this project is to build a ventilator when no professional and medical equipment is available. Easy to assemble and available components are used with a clear focus on simplicity, availability and scalability. This project started as part of the <strong>#WirvsVirus Hackathon of the German government</strong> and is intensively being worked on since, including exchange with medical experts. The work is also a selected project in the <strong>give-a-breath-challenge </strong> and <strong>The Global Hack</strong>. <em>Please check the full disclaimer as well before proceeding:</em> The material and documentation here is provided with no warranties explicit or implied.

This thing represents a further extension / variant based on our evolved design A1. Further extensions and upgrades will be posted here as well. Please check those, too. <strong>General concept</strong> A printed tube is used to measure differential pressure with two pressure sensors DPS368 from Infineon. Different configurations are shared - we focus on the simple tube with two different diameters (22 and 8mm). <strong>This design is currently used in our BVM ventilator design.</strong>
