Open Source Ventilator

(1/11) > >>

Hi,
I just wanted to advertise this open source ventilator project:
https://gitlab.com/open-source-ventilator/OpenLung
I don't know if the situation will get so dire that this will be needed but the project revolves around using one of these hand operated ventilators and squeeze them in an automated way. The concept I am currently working on is the one named "Sucker Punch". 8)
As a lot of us are stuck at home this would be a very constructive use of your time and skills. :)

Blitzschnitzel:
OK I guess the "What did you buy today?" thread is more popular. :-\

What's wrong with dozens of actual designs in current use?
Are these devices likely to ever, even in the most dire of circumstances, be used? Whoever administers this DIY thing is open to so many malpractice lawsuits suits they might as well let the patient die.
Let's not invent hot water. It's much easier and faster to licence an existing design and crank up production of those.

They are 'life support ventilators' and tend to kill people if they malfunction. So the medical safety standards for them are pretty strong and add redundancy/complexity.
AvE used a couple 555 timers and solenoids, pressure regulators, gauges.

In Italy they are doing on the spot decisions about who gets to live and who has to die right now, because they lack ventilators. I think the normal rules don't apply anymore. This is a stop gap measure about making the cheapest and quickest to produce ventilator and in Africa they don't even have enough ventilators for the everyday needs. If I have to choose between maybe dyeing from a janky ventilator and definitely dyeing, I am going to choose the janky ventilator.

@floobydust
Yeah I've seen AvE's videos and that is a cool design but he claims that you can't administer oxygen to the hand pumps, which is simply not true.
