3D Printed Ventilator Valve From Recent Covid-19 Coronavirus News News: Also got an explanation on how they work. They are a blend valve. The take oxygen from the top and push it into your mask. They suck in air as they pass so you don't get neat oxygen. The side tube acts as a bleed to adjust the amount. Also told to print one for every member of my family, chances are, if you turn up with one and they don't have any, they will let you use it. You may have seen it in the News about an Italian company 3D printing parts for live saving ventilators in hospitals. Well this is the part. Any idea how it works? I would love to know how we can test the quality of these parts before bagging them up.
