OpenVent - 3D printable (C)O2 sensor tube and housing

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> Respiratory ventilators, depending on type and operation mode, require a set of different sensors, including typically CO2 and O2 sensors. Without additional measures, the sensors are directly exposed to the humidity and viruses in the exhaled air. If the sensors are not sealed with the tube, the housing may be used to seal the module. The bottom part of the housing includes pins to hold the sensor PCB in place. More about the electronics, sensors and software are covered in our GitHub pages. <strong>This design is typically being used in conjunction with our open source BVM ventilator or our open source CPAP ventilator. Please check those designs as well.</strong>
