The Decathlon diving mask transformed into a respirator with a 3D print

Cristian Fracassi a construction engineer architect with a doctorate in materials engineering and a master's degree in economics; the CEO of Isinnova, a company that "develops ideas and helps companies and individuals in realizing or improving their projects", and jumped a few days ago to the honors of the chronoche for having conceived and 3D printed a valve necessary for the respirators of the Mellini di Chiari hospital.

The idea turned out to be positive, the hospital tested the first sterilized and hand-made pieces, with holes of less than a millimeter and after a few hours from the press ten patients were breathing thanks to the Isinnova valves. The team is producing hundreds of them, without receiving anything in return from Mellini et al Corriere della Sera the company said: We don't care about money. If needed, we could also make them for other hospitals. The printers do not turn off despite a few phone calls to the lawyers' vitriol: a fairly complicated affair: the company that produces the valves accused us of copying the product. Our lawyers will take care of it.

After the idea of ​​the 3D printed valve, the idea of ​​transforming the Decathlon snorkeling mask into a hospital C-PAP mask for sub-intensive therapy was born from the company of Fracassi, a component that, apparently, is missing in this moment in Italian hospitals.

Fracassi tells a Business Insider Italy that Lidea came to a former primary, Dr. Renato Favero, the qiale after reading 3D valves, contacted us and said: I have the idea of ​​transforming a diving mask into a fan. Can you give me a hand? He gave us three hours of anatomy lesson and then he said to you.

a prototype was created and the fitting was called "Charlotte valve. Decathlon – the creator, manufacturer and distributor of the Easybreath snorkeling mask – also liked the idea and the latter decided to collaborate by providing the CAD drawing of the identified mask. In this way it was possible to study the mask thoroughly, to prepare modifications and to design the new component for the connection to the respirator that can already be printed in 3D.

The prototype of the diving mask with respirator is already being tested at the Chiari hospital and has been shown to be working properly. The mask can be connected directly to oxygen via the wall outlet, making the respirator superfluous. Not a replacement for the pulmonary ventilator, Fracassi spiea, but it can be used in emergency rooms, where patients remain for three days waiting for a bed. Thanks to this mask, they can now wait for a bed while staying under oxygen and without polluting the environment.

Fracassi further explains that anyone can print it freely, provided it is not used for commercial purposes. The valve (here you can find more details and the files that can be downloaded) has been patented "to avoid any speculation on the price of the component" but the patent "will remain free for all hospitals in need to use".

Isinnova reiterates that neither the mask nor the valve connection are certified and their use subordinate to a situation of mandatory need. Use by the patient subject to acceptance of the use of a non-certified biomedical device, through a signed declaration. Healthcare facilities in difficulty can purchase the Decathlon mask and agree with 3d printers who make the piece and can supply it.
