MOSCOW, November 21. Siberian Federal University scientists have created a system for continuous monitoring of the heart, blood vessels, lungs and a number of other body systems. According to them, a matchbox-sized device that has no analogues allows for detailed visualization of the condition of organs. The results were published in the journal Biomedical Engineering.
Scientists from Siberian Federal University (SFU) have created a high-precision portable multifunctional device for continuous monitoring of the functional state of the body. Daily monitoring is a method of continuous monitoring of the performance of the heart and other organs using a portable recorder that the patient carries with him.
Such an analysis, according to experts, can be very useful both in prevention and in the diagnosis and treatment of various cardiac and other pathologies, which today requires research in clinical settings and the work of highly qualified personnel. In addition, the analysis is limited due to the size and cost of the devices.
The device created at Siberian Federal University allows, without the help of x-rays, to visualize in detail a number of key systems of the body and detect foci of pathologies in them. One of the priority, but far from the only application of the new system is the prevention of consequences of COVID-19, the authors reported.
The new biotester, which can be produced from Russian-made components, has a relatively low cost and miniature dimensions — 7x50x70 mm. According to the creators, there are no similar systems in the world today.

“We supplemented the electrocardiosignals, traditional for daily monitoring, reflecting conductivity indicators of the nervous system of the heart, with data from other sensors — a phonocardiogram, which reports the work of the muscular system of the heart, and a recording of lung sounds, which allow us to study the bronchial system and the degree of damage to the lungs,” said the professor Department of Instrument Engineering and Nanoelectronics, Institute of Engineering Physics and Radioelectronics, SibFU Gennady Aldonin.

During the diagnostic process, the user is not limited in any way; even active sports activity does not interfere with the operation of the device, the creators emphasized. To display monitoring data, the biotester communicates with a smartphone or computer using Bluetooth, WI-FI and cellular networks.
“To assess the state of the body’s systems, we used the wavelet transform method, based on the analysis of wavelet spectra of biosignals. It makes it possible to identify all branches of bionetworks and “see” the conducting nervous system of the heart, the circulatory system from the heart to the vessels, bronchial and other biosystems, and there are also heterogeneous defects in them,” Aldonin explained.
The joint analysis of these parameters, according to scientists, also makes it possible to indirectly record blood pressure, changes in blood viscosity from sugar (in diabetes) and prothrombins in the blood and a number of other characteristics of the body.
The research team has successfully completed testing of prototypes and in the future, based on the proposed development, they intend to implement a non-invasive coronagraphy system, which will allow prompt diagnosis of early signs of ischemia and other heart diseases.
The research was carried out with the support of the Russian Foundation for Basic Research grant No. 19-37-90072.
