Furthermore, 3D cad file is free to download and available for everyone! (link and sources at the end) Valve is free to print and use!
Additional infos: the valve is designed to work with Decathlon mask. This "home made" ventilator mask has been tested at Como hospital, due to lack of medical masks, and it works fine!! The photo has been uploaded yesterday, by Como's hospital doctors.
The valve is easy to make since everyone who has a 3D printer can make it at home/studio and supply hospitals that need it. It's also easy to assemble: in fact video tutorial are available on the inventor's - Cristian Fracassi - website. To know how this exactly works, watch the simple short video on the website!
Modified masks help breathing patients with mild symptomps.
Please, if you know your local hospital has limited stocks of masks, consider to propose managers this solution. It may save several lives!
Little clarification: Cristian patented the valve only to avoid makers could make profit on it! He shared CADs just because he wanted this valve to be free forever!
Clarification n2: Cristian's printable valve is designed SPECIFICALLY for Decathlon (which gave him mask's CAD designs for free) masks. That's why I named the brand! I'm not in the position to suggest this product to go scuba or snorkeling for 2 reasons: I have no experience at all about and I'm not interested it their underwater functioning. I just want people to know that it can be used in hospital to help patients breathing!
Clarification n3: these masks has been designed in collaboration with Dr. Renato Favero, former head physician of the Gardone Valtrompia Hospital, and tested on healty volunteers, monitored by doctors, before be applied to patients!
UPDATE: some of you asked how to supply italian hospitals with 3D printed valves. If you are a MAKER and want to help hospitals, you can go to Cristian Fracassi's site and leave your contacts info! Hospital in need will contact you to find together a way to supply 3D printed valves!!!

Disclaimer: I'm not related in ANYWAY with Cristian Fracassi or Decathlon. This is no ads. I just think this may help A LOT of people. As you can see from my profile I'm kinda a lurker on Reddit: been here since years, but almost never posted something.
GOLD UPDATE: whoever gave me gold, I thank you. BUT please don't give me gold anymore. Instead, consider to donate that amount of money to any italian hospital of your choice from this list: https://italianonprofit.it/donazioni-coronavirus/ . Money will go directly into hospital's bank account.
So that is not a ventilator, that seems to just be a way to give oxygen to the patient.
A ventilator is a machine that moves the air in and out of lungs. And they can create a lot of issues. This is because normally, like right now as we are sitting and browsing reddit instead, our lungs work on negative pressure. Your chest cavity expands in volume, decreasing the pressure which draws air in from the outside.
A ventilator changes this to a positive pressure system, it is pushing air into your lungs. With these severe ARDS(acute respiratory distress syndrome) patients breathing has basically become too difficult to do unassisted, and often doctors will preemptively intubate them and put them on a ventilator.
This mask appears to be helping minimize the spread of COVID19 in hospital, which is a serious problem. For patients who don’t require intubation/ventilator support but do still require supplemental oxygen there is the issue that the two common ways we give supplemental oxygen (nasal cannula and a non rebreather mask) can sort of aerosolize the virus and spread it in the area.
So this mask is still helpful (or at least it appears to be) but this is NOT a ventilator.
Edit: ARDS is ACUTE respiratory distress syndrome, not adult respiratory distress syndrome.
Edit 2: I am most likely wrong, that is probably a BPAP mask which connects to a non-invasive ventilator. There are smarter people below in the comments, read what they have to say.

@Decathlon said an hour ago that they don't have confirmation of a perfectly working solution yet.
(Not wanting to discredit, kill the mood or anything, just though it was better to share this, these kind of projects really are awesome.)
