В современной кардиохирургии для обеспечения частичной или полной, постоянной или временной замены функции сердца применяются системы поддержки, имеющие размеры, требующие проведения серьезной хирургической операции. Для обеспечения малой инвазивности требуется существенно уменьшить размеры имплантируемой части системы, что позволит вводить эти устройства через бедренную артерию.</p></sec><sec><title>Цель работы</title><p>Цель работы.

На основе анализа технологии применения системы поддержки кровообращения (МСПК) разработан ее состав, принцип работы, спроектированы основные ее узлы и элементы. При проектировании микронасоса как узла, определяющего массогабаритные параметры всей системы, используются численные и экспериментальные методы оптимизации его проточной части из условия минимизации травмы крови и тромбообразования. При разработке системы смазки и охлаждения решалась термодинамическая задача по обеспечению отвода тепла. Электронный блок управления разработан на основании накопленного опыта проектирования и эксплуатации блоков управления клинически применяемых систем вспомогательного кровообращения.</p></sec><sec><title>Результаты</title><p>Результаты. Спроектирован микронасос диаметром 6,5 мм и длиной 43 мм с требуемыми гемо- и гидродинамическими параметрами, обеспечивающий минимальную травму и тромбообразование. Определены основные параметры и спроектированы узлы и элементы МСПК (электроприводы, система смазки и охлаждения). Разработан состав и принцип работы электронного блока управления (ЭБУ), который представляет собой микропроцессорную систему управления МСПК с обратной связью. Встроенное программное обеспечение ЭБУ позволяет управлять частотой вращения электроприводов микронасоса и насоса подачи охлаждающей жидкости в требуемом диапазоне, измерять, отображать, регистрировать режимные параметры работы МСПК, а также осуществлять контроль их работы в требуемых диапазонах, обмениваться данными между ЭБУ и компьютером.</p></sec><sec><title>Заключение</title><p>Заключение.

Support systems currently used in modern cardiac surgery to provide partial or complete, permanent or temporary replacement of cardiac function are frequently characterized by large dimensions, thus requiring major surgical interventions. Low invasiveness can be ensured by reducing the size of the implanted part of such systems, allowing these devices to be inserted through the femoral artery.</p></sec><sec><title>Aim</title><p>Aim. Development of a minimally invasive micropump system to support blood circulation.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Based on the analysis of implementation of micropump circulatory support systems (MCSS), the configuration, operational principles and main components of such a system were determined. When designing a micropump, as a unit defining the weight and size parameters of the entire system, numerical and experimental methods were used to optimize its flow path based on the condition of minimizing blood injury and thrombus formation. The lubrication and cooling system was developed by solving the thermodynamic problem of heat removal. The electronic control unit was developed on the basis of accumulated experience in the design and operation of control units for circulatory support systems.</p></sec><sec><title>Results</title><p>Results. A micropump with a diameter of 6.5 mm and a length of 43 mm with the required hydro- and hemodynamic parameters was designed. The device ensures minimal trauma and thrombus formation. The main MCSS parameters, as well as its main components (electric drives, lubrication and cooling systems), were defined. The configuration and operational principles of the electronic control unit (ECU), consisting in a microprocessor-based control system with feedback, were developed. The ECU built-in software manages the rotational speed of the electric drives of the micropump and coolant supply pump in the required range. In addition, the software is used to measure, display and register the MCSS operational parameters, as well as to monitor their operation in the required ranges and to exchange data between the ECU and the PC.</p></sec><sec><title>Conclusion</title><p>Conclusion. All the necessary documentation for the MCSS nodes and components was prepared. These nodes and components ensure the hydro- and hemodynamic parameters required for the use of the developed minimally invasive micropump system. Future work will address the stages of MCSS assembly and debugging.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>поддержка кровообращения</kwd><kwd>проектирование</kwd><kwd>микронасос</kwd><kwd>электронный блок управления</kwd><kwd>система смазки и охлаждения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>circulatory support</kwd><kwd>design</kwd><kwd>micropump</kwd><kwd>electronic control unit</kwd><kwd>lubrication and cooling system</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке ФГБУ "Фонд содействия инновациям" (договор № 3052ГС1/44987 от 04 июня 2019 г.).</funding-statement><funding-statement xml:lang="en">The work was supported by the FSBI Innovation Promotion Fund (Agreement No. 3052GS1/44987 dated June 04, 2019).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Иткин Г.
