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

thingiverse

During the COVID-19 pandemic, it became glaringly obvious that a lack of medical equipment can have a devastating impact. Often, even simple equipment and designs can be lifesavers when no professional gear is available. This repository contains general information about an open-source ventilator device. The primary goal of this project is to build a ventilator in situations where professional and medical equipment are scarce. Easy-to-assemble components are used with a clear focus on simplicity, availability, and scalability. This project began as part of the #WirvsVirus Hackathon of the German government and has been extensively worked on since, including collaboration with medical experts. The work is also a selected project in the give-a-breath-challenge and The Global Hack.

This design represents a further extension or variant based on our evolved design A1. Further extensions and upgrades will be posted here as well. Please review those too. General concept: 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 can be found on our GitHub pages. This design is typically used in conjunction with our open-source BVM ventilator or our open-source CPAP ventilator. Please review those designs as well.
