As hospitals face an overload of Covid-19 sufferers struggling to breathe, modern medical employees are turning to snorkelling masks from sports activities shops to cease their lungs collapsing.
The concept began in Italy, the European nation worst-hit by the coronavirus pandemic, with hospitals in different nations taking notice and including their very own particular medical elements to make it work.
One such is the Erasme Hospital on the outskirts of Belgium’s capital Brussels. It’s connected to town’s ULB college — and thru it to a personal spin-off, Endo Instruments Therapeutics, whose know-how in 3D printing for medical use has proved invaluable.

“They are to be used for patients with severe respiratory problems. The aim is to avoid having to intubate the trachea of the patient and put them on a respirator,” stated Frederic Bonnier, a respiratory physiotherapist on the hospital who additionally teaches on the college.

He spearheaded the design of a custom-made valve that matches to the highest of full-face masks, the place the snorkel is supposed to go, permitting them to hook up with normal BiPAP (bilevel optimistic airway strain) machines that feed pressurised air into masks.
This helps stop the collapse of alveoli, lung air sacs wanted for the consumption of oxygen into our our bodies and the exhalation of carbon dioxide. Pneumonia introduced on by Covid-19 inflames the lung membrane and fills these sacs with liquid.
Cease-gap answer
Within the worst-case infections, sufferers need to be hooked as much as respirators in intensive-care items.
However respirators are in desperately brief provide worldwide due to the sheer variety of sufferers.

The snorkelling masks answer might be a stop-gap measure for sufferers on the point of intensive-care remedy however for whom no beds nor respirators can be found. Hospital masks for the less-intensive BiPAP machines are additionally missing.
Bonnier stated that from Monday, he might be testing 50 of the masks on sufferers.
They’re the identical model as these utilized by Italian medical doctors, donated by the French sportswear retailer Decathlon that has shops worldwide. The masks themselves are made in Italy.
He defined they had been way more comfy than the hospital ones that match over the nostril and mouth, biting into the pores and skin. However he cautioned they weren’t examined to medical requirements, which means they had been one-use solely, unable to be sterilised between sufferers.
The Italian design for the 3D-printed valve additionally wanted transforming.
“It seemed fairly complicated to make, pretty heavy, not very comfortable. So we had the idea to go a little further by thinking on it and developing our own connection part,” he stated.
The brand new plastic valve connectors have now been 3D-printed and are able to be examined.
Bonnier added that well being staff in Covid-19 wards might additionally use the masks for cover in opposition to the virus. However he fears the general public will begin panic-buying them, thereby depriving hospitals of a probably life-saving product.
He additionally stated that, even when the checks show conclusive, there have been nonetheless questions on what number of such masks might be made obtainable by sporting corporations, below what circumstances.
Retailer cautious
Studying of the emergency use being fabricated from its snorkelling masks, Decathlon expressed “interest” —but in addition prudence.
“At the moment we don’t have confirmation that these solutions really work,” it stated on its Twitter account.
“If we see successful try-outs, and these hospitals confirm to us that some tests work, then we’ll keep you informed. But in the meantime, beware of unsourced and unverified information spread on social media in recent days.”
