Emergency Ventilator: Medtronic Design Review

Medtronic has generously published their ventilator design. I'm going to review the documentation and see what insights I can glean. Come and join me, offer your insight, and let's learn about one of the most important machines that humans can build over the next few months.

It looks like this is covered in US Patent - US 2010/0189744A1. Everything lines up pretty close to what Charlie is saying. I think they are using the word 'turbine' but from the wording in the patent, it is electrically driven. Probably PWM.

In any rate, Great Job! I appreciate you going over this in detail.

If there's a fan propelled by a motor, you usually call it a pump or a compressor, not a turbine. A turbine is a device to extract (& not inject) energy from a fluid stream. But for some reason the ventilator people use the word turbine to describe compressors. Unless it's an actual turbine run off a compressed air line, of course.

Hello, great video, someone has information or specifications of the "Oxygen Solenoid Valve"

Did anyone have luck finding the turbine ?

Did medtronic remove the design from their website? The page is unavailable if I try it now.

Remember kids, the legal mambojambo is really hard and if you are working with open source ventilator project, watching or looking or refering to MEdronics designs (documents) may contaminate your project and Medtronic can sue you. :( The license is only for duration of this pandemic.

Good idea to not follow the path most followed by others.
