Amidst the fight against the coronavirus, Rostec increases the output of its medical equipment. Since the beginning of the pandemic, the corporation has supplied a total of over 200,000 units of equipment essential for combating the virus. Rostec's holding companies produce resuscitation equipment, defibrillators, touchless thermometers and thermal vision cameras.
Prevention measures become particularly important for stopping the proliferation of COVID-19. They are helped by modern technologies and virus-eliminating devices. We present Rostec’s efficient developments, which help minimizing the probability of transmission of the coronavirus infection.
Foggy outlook for the virus: cold fogging disinfection arches
Cold fogging is one of the technologies used for premise disinfection. Such fog is essentially a disinfecting cloud, which consists of micro (up to 80 mkm) particles of treating liquid. This allows good dispersion of the active substance in less accessible spots.
The cold fogging treatment is effected by a special device, the generator. There are a number of generator types, which vary both in terms of their working principles and their mobility. For example, in the Liniya Zdorovya (Line of Health) set by Ruselectronics holding company, such devices are embedded in the arch. A disinfection arch is installed at the entrance to a premise and it takes it just a few seconds to disinfect one’s clothes and open skin areas using the cold fogging technology. The cold fog makes no harm to one's clothes, and is completely safe both for humans and animals. Up to 12 people per minute can pass through the arch.
During the pandemic, such cold fogging disinfection arches are extremely useful at entrances to various institutions, particularly, to airports and railway stations, hotels and restaurants. The new device is already being used at the Federal University of Crimea, as well as at a number of organization in the Nizhny Novgorod Region, including the territory of the historical complex of the Kremlin of Nizhny Novgorod. Ruselectronics prepares for new deliveries: the holding company announced its readiness to produce up to 50 sets per month, and to increase the production in case of high demand.
Corona gets red light: portable air sanitizers for taxi
Taxi rides become increasingly popular amidst the pandemic. Traveling by taxi is considered to be safer than using public transport. Doctors remind the simple rules to be observed both by passengers and by drivers to maximize their safety: wear masks and gloves, use hand sanitizers, and aerate the interior of the car often. One of the taxi services has recently equipped its cars with a gadget, which will help both passengers and drivers to feel safer. These are compact air sanitizers with ultraviolet diodes produced by Ruselectronics. The new product of the holding company is perfectly suitable for use in a car: the miniature gadget only weights 100 grams, measures about 10 x 4 cm, and can function continuously throughout the day.
The air passes through its sanitizing camera eliminating all dangerous bacteria and viruses due to the bactericidal effect of an ultraviolet diode, which emits waves of 270 nanometers.
Mini air sanitizers by Ruselectronics have already been supplied to 12 Russian cities. The gadgets are used by Vezet taxi service in Moscow, St. Petersburg, Novosibirsk, Yekaterinburg, Omsk, Volgograd, Ufa, Perm, Samara, Krasnodar, Kaluga and Sochi. When calling a taxi, the mobile application notifies the passenger that there is an UV air sanitizer functioning in the cabin.
Virus detector: a device to detect coronavirus in the air
In June 2020, Zverev plant in Krasnogorsk (a part of Shvabe holding company) performed the state acceptance test of a device intended to detect viruses in the air, including the coronavirus. Detector BIO was developed by the Gamaleya Research Institute of Epidemiology and Microbiology.
The automated device is capable of the simultaneous detection of up to 86 viruses and bacteria, as well as toxic substances. It takes Detector BIO 10 to 30 minutes on average, to analyze an air sample. The analysis uses two methods at once: the real-time polymerase chain reaction and the immunofluorescence method. This approach significantly increases the test accuracy.
The results are displayed on the monitor of a computer, which the device is connected to. If any toxins, bacteria or viruses are detected, the decision is made to perform a sanitizing treatment. The device can be used in a large variety of places of mass gathering of people, including railway stations, airports, and metro.
Catch and neutralize: a new generation of quartz lamps
Amidst the pandemic, the demand for portable and fixed bactericidal air sanitizers by POZIS (included in the contour of management of the Technodinamika holding company of Rostec Corporation) increased significantly. The Company has been successfully manufacturing these products since 2009. Since the start of this year, POZIS has increased its disinfecting equipment production more than seven times. The company saw a rise in demand for its air sanitizers, in particular, the ORB-2N POZIS, ORB-2P POZIS models.
The full name of the device is “wall-mounted bactericidal air sanitizer”. It treats air and surfaces with ultraviolet rays. The ultra-violet irradiation is contained within the device case, which differentiates the modern air sanitizers produced by POZIS from the old-generation quartz lamps. A modern air sanitizer does not need to be left alone to function: air sanitizing can be done in the presence of people. The device has the highest efficiency: up to 99.9% for premises of up to 100 cubic meters.
From a dangerous virus to benign molecules: photocatalysis-based air purification system
Photocatalytic filters, a new step in air purification, are able to combat 99% of bacteria and viruses, including the coronavirus. In such filters, the ultraviolet irradiation in a particular environment decomposes microorganisms into benign molecules of water and carbon dioxide.
One of the Russian producers of such air purifying systems is Ramensky Instrument Engineering Plant, part of KRET. The enterprise produces photocatalytic air purifiers of TIOKRAFT brand. They are suitable for installation not only in health care institutions and other immovable facilities, but also, for example, on airplanes or ships.
This is not the Concern’s only innovation in the photocalysis field; the KRET experts managed to embed photocatalytic filters into personal protective equipment. The Ramensky Instrument Engineering Plant has already produced a pilot batch of respirator masks using photocatalytic technology. The respirator is now on the testing phase, but in the future, the innovation may be able to efficiently protect individuals not only from the coronavirus, but also from all other microorganisms, including Koch's bacillus.
A suite of innovative clothe: new type of anti-virus coveralls
As early as May, Rostec’s Roshimzaschita started supplying protective suits for healthcare professionals, who are on the forefront of fighting COVID-19, to Russian regions. The coveralls are produced by KazhimNII (Kazan Chemical Research Institute), an enterprise specialized on developing and manufacturing unique customized protective suits.
The development holds a particular place in Roshimzaschita’s protective equipment line; rather a standard filtering suite, it is an isolating coverall made of innovative material, that is, Barier film tissue.
KazhimNII manufactures about 10,000 isolating coveralls per months, and plans to expand its production up to 20,000 items. Now, the suit is being tested for reusability. The tests show that a doctor can wear the coverall during, at least, five shifts, provided that the suit be disinfected after each shift. The manufacturer even expects to prove the possibility of a 10-time use. The coverall costs just over RUB 2,000. Therefore, its reusability would relieve health care institutions from additional costs amidst the complicated epidemiological situation.
