3D printing lets hospitals make ventilator substitutes with common equipment

Materialise 3D Prints Non-Invasive PEEP Masks to Alleviate Ventilator Shortage

Many hospitals around the world currently have an alarming shortage of mechanical ventilators, which they can use to treat COVID-19 patients. Responding to this crisis, Belgian 3D printing company Materialise has developed a 3D-printable device that transforms standard equipment available in the majority of hospitals into a mask that can help coronavirus patients get the oxygen they desperately need into their lungs. The company’s smart solution promises to create high positive pressure in patients’ lungs without the use of a traditional ventilator.

“The 3D-printed connector converts this standard equipment into a non-invasive PEEP mask that can be connected to [an] oxygen supply to facilitate breathing for coronavirus patients,” Bram Smits, external communication manager for Materialise, told Digital Trends. “This solution gives patients an extended period of time before mechanical ventilators are required for treatment, and helps transition them off ventilators earlier, freeing up these devices for patients in critical need. By using standard medical equipment, including a non-invasive ventilation (NIV) mask, a filter, and a PEEP valve, the solution is simple and familiar to use for medical professionals.”

Like many 3D printing companies and professionals, the folks at Materialise say they were spurred into action by their realization that additive manufacturing can help right now in a way that few other industries can.

“We looked at various routes, including printing parts for ventilators and printing protective mouth masks,” Smits continued. “We contacted clinicians to better understand what the medical need of the patients was. In these conversations, we understood that the need was to have a solution for patients that need more oxygen and positive pressure before they need to be intubated — and this in a way that the medical staff was protected as well, avoiding air contamination as much as [possible].”

Creating their solution — including prototyping, testing, and iterating — took just a single week. Of course, while 3D printing makes it fast to create medical devices, it’s still crucial that they comply with regulations to ensure safety of patients and caregivers. Currently, the team at Materialise is supporting a clinical trial to put the technology through its paces.

As to what this means for patients, Smits said, “We hope to have it tested, registered, and available on the market by mid-April.”

3D printers are finally affordable. Here are the best models under $500
anycubic photon review 3d printer xxl 2

The 3D printing market has seen quite a few changes over the last few years. In just the span of a decade, the barrier to entry has dropped from well over several thousand dollars to under $200 in some cases. However, all entry and mid-level printers are not made equal. We have a few suggestions for prospective buyers and other information regarding alternatives not found on this list.

To some veterans of the 3D printing scene, this list may seem like it lacks a few of the most commonly recommended printers for newcomers. This is by design. Our list only considers printers with tested components from proven, reliable vendors. That's why we chose the Monoprice MP Mini v2 as our top pick--it's reliable and easy to use. We have avoided any printer with a frame primarily made from interlocking acrylic pieces and anything historically unreliable.

Hit takers: The cutting-edge engineering making football helmets safer than ever
helmet engineering

Football helmets aren’t what they once were. And, while most of the time that turn of phrase is used to describe how things used to be better in the good old days, in this case, it’s certainly not.

Helmets are, in some senses, the most crucial bit of protective gear football players wear on the gridiron. Over the years, they’ve evolved from the leatherhead shell of yore to take advantage of breakthroughs on the material science front. Today’s big four helmet makers include the legacy brands Schutt and Riddell, in addition to comparative newcomers like VICIS and Xenith.
