According to the Federal Service for State Statistics, cardiovascular diseases (CVD) rank first in the mortality structure in the Russian Federation. Auxiliary circulatory devices (ACD) are various mechanical systems that help the heart maintain adequate blood flow and improve the overall condition of patients with CVD. In order to assess the characteristics and safety of ACD systems, it is necessary to conduct complex tests on special stands simulating the human organism. Evaluation of the applicability of thermoanemometric fluid flow measurements in hydrodynamic simulation stands of cardiac activity. The developed measuring unit, which is part of the hydrodynamic bench, is able to carry out volume flow measurements at the level of serial samples of rotary flowmeters. With the help of such stands it is possible to study the influence of various factors on the work of the heart and vessels, as well as to test new methods of diagnosis and treatment of cardiovascular diseases. The experimental results obtained in the article are of great practical importance for the creation of a biotechnical system for studying the efficiency of artificial circulatory devices.
