engineers use 3D printing hack to turn scuba masks into ventilators
sporting goods retailer decathlon is contributing to the fight against coronavirus by sending makeshift ventilators to hospitals in northern italy. the company has converted its line of snorkelling masks with the help of engineers from an italian research institute who used a 3D printing hack to transform the equipment.
the ventilators were developed with the help of engineers from the institute of studies for the integration of systems (ISINNOVA) in rome. the project was prompted by a request from the head physician of a hospital in gardone val trompina in the italian region of lombardy, one of the regions hit worst by the coronavirus, to address the ventilator shortage.
cristian fracassi and alessandro romaioli, engineers at ISINNOVA, had the idea of making masks out of decathlon‘s scuba equipment and in three hours, created a prototype for a 3D printed valve that successfully converted the gear into a ventilator mask. the pair then uploaded the means of converting the masks online, creating a video detailing the process which you can see above. it shows how other hospitals with access to a printer could make such a mask themselves.
in severe cases of COVID-19 a patient’s lungs become inflamed and filled with fluid which makes it difficult for them to breathe. in these cases a ventilator could mean the difference between life and death.

Its a ventilator, that can be connected to a pressurised oxygen supply or to a C-PAP (continuous positive air pressure) supply so making it easier for people to breath. (They also making the replacement valves for the respirators used in intensive care).

what about the masks that people use during spray painting? those masks have replaceable filters too and prevent toxic fumes and dangerous airborne particles from being inhaled
This seems to be a design for a filtering mask NOT A VENTILATOR! Others have made this point on here and the comments have been deleted. Please correct the misleading information.
Thank you
These could also be used for personal protection of seniors need to get out . Personal tanks and carts could be used .
Ventilators ? Look like respirators . Which one?
Use of pure copper filter into the mask it will prevent bacterial partials inside the mask,so there will be no need of intense bleaching the musk, for cleaning alcohol combined with vinegar can much safer disinfect the masks.
The research work has been done by other people days before. This is the full documentation about it.
