One of the biggest immediate problems that coronavirus is causing is the massive number of people who require intensive care and oxygenation in order to live through the infection long enough for their antibodies to fight it. This means that the only way to save lives at this point – beyond prevention – is to have as many working reanimation machines as possible. And when they break down, maybe 3D printing can help.
Christian Fracassi, founder and CEO of Isinnova, an Italian engineering startup, heard the call for help last Friday. The hospital in Chiari, in the Brescia area of northern Italy where the coronavirus pandemic has hit hard, urgently needed valves for its respirators in order to keep patients who required oxygen alive. The manufacturer couldn’t provide them quickly enough and the hospital was desperate.
Fracassi immediately started tinkering with his engineers to reverse-engineer a 3D-printed version of the official part. Called a venturi valve, it connects to a patient’s face mask to deliver oxygen at a fixed concentration. The valves need to be replaced for each patient.
By Saturday evening, Fracassi had a prototype, and, the next day, he brought it to the Chiari hospital for testing. “They told us, ‘It’s good. It works. We need 100,’” says Fracassi, who is 36 and holds a Ph.d. in materials science with a focus on polymers. “We printed 100 of them on Sunday, and we gave all the pieces to the hospital. They are working very well.”
