At the Samara State Medical University of the Russian Ministry of Health, together with leading engineers of the Samara National Research University named after Academician SP. Koroleva created a device to simulate intra-arterial circulation. This was reported to socialbites.ca in the press service of the program “Priority 2030” of the Ministry of Education and Science of Russia.
“The device is a closed system that simulates an arterial vessel. The basis of the device for modeling intraarterial circulation is a glass tube of a rotameter with inlet and outlet ends (a device that determines the volumetric flow of gas or liquid per unit time). In this device, arterial blood flow under various rhythm conditions “We can also mimic plaque in a vein by attaching a special diaphragm,” Olga Germanova, author of the project and director of the International Center for Science and Education in Cardiovascular Pathology and Cardioimaging, told Gazeta. ” he said. Ru.
Flexible silicone tubes are attached to both sides of the rotameter and connected to an electric pump with various operating modes (imitation of pulse waves in a normal rhythm, extrasystole and atrial fibrillation). The authors add to this system an aqueous solution of glycerol diluted with water corresponding to the viscosity of the blood.
According to the expert, various indicators can be added to the model through a special valve, for example, stationery ink for coloring liquid flows or a pressure sensor.
It will be applied in the field of experimental cardiology and will help doctors to study the hemodynamics of arterial vessels with correct heart rhythm and arrhythmias.
“The experimental part is done to prove and objectively evaluate the hemodynamic patterns we obtained in the clinical part of the study. Sometimes it is experimentation that allows us to understand and explain ongoing processes, thanks to its visibility, ease of use, and repeatability. I am sure that interesting new discoveries await us that will be important for a better understanding of the circulatory system as a whole,” explains Germanova.
used to be a doctor discretion “Vaccination against hypertension”, in which one dose reduces pressure for six months.
