3D intensive care: anesthesia and ventilators have become safer in Russia

Roszdravnadzor has registered a new line of anesthesia and respiratory devices and ventilators adapted specifically for Russian clinics and protected from failures. The "Cedar" and "Willow" series devices are designed to replace their foreign counterparts in hospitals. The equipment has been developed taking into account the real working conditions of domestic clinics and is deeply adapted to our standards, from compatibility with anesthetics to resistance to pressure fluctuations in gas lines. Experts note that the import substitution of such equipment is a matter of the stability of the healthcare system. At the same time, consumables, sensors, maintenance, calibration and software updates are needed for its operation, experts told "Izvestia".

New anesthesia machines and ventilation systems

Russian scientists have presented several new developments in the field of intensive care equipment, told "Izvestia" at Sechenov University. The domestic line of anesthesia and respiratory devices and artificial lung ventilation devices, created by the university in cooperation with the manufacturer of medical equipment NPO "RMed", received registration certificates from Roszdravnadzor.

These are devices of the "Cedar" series, designed to provide anesthesia and maintain breathing during operations. They provide accurate delivery of anesthetics, ventilation of the lungs in basic modes and monitoring of a wide range of indicators. The equipment is suitable for adults and children, including newborns.

""""Roszdravnadzor" also registered Iva series ventilators — models "Iva I30" and "Iva I50". The first one is designed for respiratory support and can be used in intensive care units, intensive care units and during patient transportation, experts said. The second is a more complex system designed for adults and children. Its field of application is intensive care, intensive care, operating rooms, as well as transportation within and between clinics.

Prescription for independence: the main medical breakthroughs of the Russian Federation in recent years

Russian scientists are actively creating unique technologies and drugs

The development of medical equipment took about two years. They took foreign solutions as a basis, the university said. During the reengineering, the team improved imported medical products and adapted them to the conditions of Russian clinics. In particular, she expanded the compatibility of devices with modern domestic and foreign inhalation anesthetics, ensured stable and safe operation with various types of respiratory circuits common in hospitals, improved the graphical interface and increased the resistance of devices to fluctuations in the parameters of centralized gas lines.

—Sechenov University became the first among medical universities in the Russian Federation to implement a project to reengineer complex medical devices for mass production," said Alexander Kulish, Director of the Biomedicine Science and Technology Park at the First Moscow State Medical University. — Such equipment is in high demand today not only in our country, but also abroad.

The university's leading engineers worked with doctors to improve the characteristics of anesthesia and respiratory devices and ventilators, he said. The participation of clinicians, the end users of medical equipment, has made the devices more convenient for Russian doctors.

Reengineering of medical equipment in Russia

According to Alexander Zorin, CEO of NPO "RMed", localization ensures a full cycle of production, assembly, configuration and testing of devices in our country.

— All key stages of the production cycle — from the installation of printed circuit boards and housing elements to calibration, output control and serial production — are implemented on the production site of our company and partner sites. Within three years, we plan to fully switch to domestic components manufactured in the Russian Federation," he said.

The safety of medical equipment of this class depends on the accuracy of the measuring circuit and the predictable behavior of the device in non-ideal conditions. ""The accuracy of the delivery of anesthetics and respiratory mixture, the depth of monitoring, the logic of alarms and the operation of protective mechanisms against excessive pressure are important," Marina Chumakova, a leading market expert at NTI "Helsnet", told Izvestia.

— But the key here is that the developers separately note the stable operation with different types of respiratory circuits, compatibility with modern inhalation anesthetics. It is these factors that in everyday practice can most often take equipment beyond the normal mode," the expert noted.

It is suitable for people with metal implants and can be used at the bedside of bedridden patients.

""Cedar" and "Willow" product lines are the first time that a medical university has brought the reengineering of complex life—supporting equipment to serial production, and this is why the project is interesting to the market," said Andrey Vilensky, Director of the Center for Rehabilitation and Neurotechnology at RTU MIREA, CEO of the "STC Meditex" company.

— Ventilators and anaesthetic and respiratory equipment are life-support equipment: its failure or unavailability directly threatens the patient's life, so there is no right to make mistakes or pause. Own production of such products is not a matter of economy, but of the sustainability of the healthcare system. At the same time, it should be borne in mind that the device, as a rule, has been working in the clinic for seven to 10 years, and all this time it needs supplies, sensors, service, calibration and software updates," he noted.

The developers claim increased resistance of the devices to fluctuations in the parameters of centralized gas pipelines. This is an important characteristic: the equipment must maintain the set ventilation parameters over the entire operating range of oxygen pressure and operate safely in case of deviations. In hospitals with worn-out gas systems, such a safety margin may be more important for the patient than having an additional ventilation mode, the specialist noted.

In the future, the specialists plan to expand the range of medical equipment and products for reengineering and localization of production. In the future, they intend to switch completely to Russian components, which should ensure stable supplies and reduce dependence on imports.
