Another open source ventilator, in Danish. https://www.dr.dk/nyheder/regionale/nordjylland/danske-forskere-har-brugt-blot-14-dage-paa-lave-en-simpel-respirator |

So did we give up on this? FWIW, if anyone can deliver a hardware prototype, I'd have a go at writing the software. I've no experience with medical, but have worked in other safety critical areas. Edit: The main code for the Medtronics PB560 runs to 53,000 SLOC. That's around 135 programmer-months, a little over 12 years of effort. I hope that gives some useful perspective... Edit2: sorry I miscounted. There are nearer 96,000 lines of code. So double that timescale! (excluding blank, comment only lines but including C source this time :)) |

At SEAT car factory in Martorell in Spain they needed one week to setup a production of 300 devices per day. They are using on stock wiper motors plus SMPS blocks to operate rubber ventilation bags. The device has about 110 parts. Volume per cycle can be adjusted mechanically, speed gets adjusted by supply voltage. Apparently medical doctors preferred something that doesn't need supervision. Don't know how they control the exhaust valve and i did not read about backup batteries. That virus changes everything. https://www.seat-mediacenter.com/newspage/allnews/company/2020/From-making-cars-to-ventilators.html Regards, Dieter |
