The story of how it took one 23-year-old engineer a day to remake swimming masks into medical

It has been a month since the Peoples’ Friendship University of Russia joined the #мейкерыпротивковид (makers against Covid) movement and has been helping doctors and patients with 3D printing. Engineer Mark Dyachenko from the Center for Additive and Foreign Technologies of RUDN University used a 3D-printer to print 1,149 adapters for mask filters, which are used by doctors in more than 15 hospitals in Moscow.

At the beginning of the epidemic, when medical institutions faced a shortage of personal protective equipment in the “red zone”, in Italy they came up with a technology how to make a medical mask for doctors from a swimming mask. Decathlon company was ready to give diving masks to hospitals. However, to use these masks, it was necessary to attach a special filter requiring an adapter. At the same time, the masks were of different models each needing specially designed additional parts.

Regular manufacturing would have been long and expensive, because first it would have taken producing molds for thermoplastic machines for each part and each machine separately. RUDN University Institute of Innovative Engineering Technologies (IIIT) proposed using additive, SLS (selective laser sintering) technologies and printing parts on Farsoon SS403P industrial 3D printers (Prodways x 4500).

It took RUDN Additive and Edge Technologies Center just one day to launch the production of adapters of the required parameters from certified medical plastic. Work included setting the task for the 3D printer, printing and cooling of the parts themselves, extracting and cleaning. In a day, 400 adapters of the required parameters were printed, and after two days, the Blokhin Cancer Center and the Mukhin City Clinical Hospital received the first batches of adapters and got effective and comfortable masks. Since most employees are in lockdown, part of the industrial design and logistics work was done remotely. The entire production was performed by only one engineer-technologist of the Center —a 23-year-old Mark Dyachenko!

"We began to print adapters for diving masks when it became clear that doctors lacked personal respiratory tract protective equipment. The adapter is installed on the top of the mask, to which 1 or 2 filters are attached. Each printing round makes 400 adapters, as soon as I took out the printed parts, I immediately prepared and started a new print. While the machine was printing parts, I cleaned the finished product. To print adapters, we used special medical plastic, absolutely harmless to the human body. Due to lockdown the work became more complicated, but we were always in touch with colleagues using messengers. I know that the doctors were grateful to us, and the page of one of the charitable organizations had a post with photos of our adapters and a mention of my name" - Mark Dyachenko, engineer-technologist at RUDN Additive and Edge Technologies Center.

Now RUDN has already manufactured 1,149 filter adapters for 3 mask models. Every seventh swimming mask in Russia, has become a mask for the doctors’ protection thanks to the 3D production of the Peoples’ Friendship University of Russia. They are used in 15 medical institutions in Moscow and the Moscow region.

Engineers at the Institute of Innovative Engineering Technologies at RUDN University have begun manufacturing face shields fasteners and hose holders for lung ventilators — 290 holders are already made. University experts continue experiments to improve enhanced protection medical masks.

Reference:

During one month more than 15 medical institutions in Moscow and the Moscow Region received masks with filters adapters manufactured by RUDN University:

  • A. Vishnevsky hospital
  • Meditsina JSC (Academician Roytberg’s Clinic)
  • O.Mukhin Clinical Hospital
  • M.Vladimirsky hospital
  • I.Davydovsky State Clinical Hospital No. 23
  • State Clinical Hospital No. 52
  • N.Bauman State Clinical Hospital № 29
  • V.Veresaev State Clinical Hospital No. 81
  • Hospital for War Veterans No. 2
  • Hospital for War Veterans No. 3
  • Mozhaisk Central District Hospital
  • N. Blokhin Cancer Center
  • A.Vishnevsky Surgery Hospital
  • Center for Family Planning and Reproduction
  • Russian Railways Central Clinical Hospital

Biologists from RUDN University discovered the secret of flaxseed oil with long shelf life

Biologists from RUDN University working together with their colleagues from the Institute of Molecular Biology of the Russian Academy of Sciences and the Institute of Flax studied the genes that determine the fatty acid composition in flaxseed oil and identified polymorphisms in six of them. The team also found out what gene variations could extend the shelf life of flaxseed oil. This data can be used to improve the genetic selection of new flax breeds. The results were published in the BMC Plant Biology journal.

Dentists from RUDN University Presented a New Classification of Root Canal Shape Changes

Individual characteristics of the shape and cross-section of the root canal are one of the main issues for dentists. When treating a root canal, a doctor needs to properly clean it, fill it, and carry out a rebuilding procedure so that a canal is sealed. The first stage of endodontic treatment requires detailed knowledge of root canal anatomy. A team of dentists from RUDN University studied and classified various changes in root canal shapes. The new classification will help doctors avoid diagnostic errors, better select their tools, and treat patients more efficiently.

A chemist from RUDN developed a green catalyst for pharmaceutical and industrial chemistr

Many production facilities (e.g. plastic manufacturers, pharma companies, and others) use nanocatalysts that contain palladium—an expensive component that is not sustainably produced. A chemist from RUDN University found a way to reduce palladium consumption and to make its manufacture more eco-friendly. He developed a catalyst based on a substance that comes from plant waste. Using his invention, manufacturers could cut palladium consumption in half. Moreover, new catalysts can be reused multiple times without any decrease in efficiency.
