Building an full documented Open Source Ventilator for CoVid

Comment 2

Inspiration

I knew about the REESPIRATOR project about one moth ago. At that moment they where doing some animal test, but there were no information about how to replicate the project. During theese weeks many working groups were working in improving and documenting all the aspects (firmware, hardware,...) of the prototipe. Now ther is a lot of information to almost build and deploy some working prototipes versions.

What it does

The REES is a complete mechanical ventilator for all kind of uses in an medical emergency area. Actualy we are working on the presure control mode, but looking ahead for other two different control modes the machine can deal with. With the publised information it's possible to build the device with usual digital fabrication tools. All the patient side accesories are comercial and standard ones. As an open source project, bricolabs-rees-2020 is a branch made by the maker asociation Bricolabs, located in A Coruña, Spain.

How I built it

We are using the cutting files for building the machine. The software is being coded by a highly skiled team of engineers. For the pneumatics we are using standardsanitary devices. Once the information of the first release is completed the machine can be buidt in a few hours.

Challenges I ran into

The first challenge is to build and test a complete prototipe. This will be tested in mechanical lung, and animal models in this first phase. Working with a big group of teanmates is another important challenge, especilly with the special dificulties during this isolation days. In any case, the main challenge is building a complete set of information and documents so anyone inthe world can reproduce the equipment, and adapt it to the resources they have in hand. This project os not about building lots of units of a good product. It's about deploying enought reliable information so anyone in the world that need a ventilator can buildt a good product to solve their needs, related or not with the CoVid.

Accomplishments that I'm proud of

This weeks of developing solutions, and preparing information about the requirements and solutions adopted. Building a working prototipe (not completelly funcional at this moment)

What I learned

A lot about team workig and working pipeline. A lot about real time coding, EMI inmunity and a lot about mechanical respiration, medical needs,...

What's next for bricolabs-rees-2020

Completing the release 1 working prototipe. Complete and deploy the building instructions, mauals, software manuals,... Continue with the release 2 introducing new working modes and functions. Follow the prototipes and working groups that made a replica of the ventilator in the world. What kind of adaptations they do and how it's going with them.
