Предложенный вариант крыльчатки ротора включает как набор из основных лопастей, формирующих большую долю напора, так и дополнительных укороченных. В данном исследовании проанализированы условия эксплуатации центробежного насоса в терапии с применением аппаратов ЭКМО при давлении 350 мм рт. ст. и расходе 5 л/мин. Произведены расчеты параметров потока жидкости, характеризующих вероятностный уровень гемолиза. Основным результатом создания новой модели РК было получение большей площади зон касательных напряжений со значениями менее 10 Па, снижение времени экспозиции и индекса гемолиза. Комбинация лопастей демонстрирует лучшую характеристику эксплуатации, чем оригинальная конструкция, что подтверждается как математическими, так и стендовыми испытаниями разработанных экспериментальных моделей с применением донорской крови.</p></abstract><trans-abstract xml:lang="en"><p>This study focuses on the evaluation of a modernized impeller for the RotaFlow centrifugal pump (Maquet, Germany), carried out as part of efforts to design a domestic counterpart. The proposed impeller features a combination of primary elongated blades, responsible for generating the majority of pressure, and secondary shortened blades. The investigation examined pump performance under extracorporeal membrane oxygenation (ECMO) therapy conditions at a pressure of 350 mmHg and flow rate of 5 L/min. Computational analyses were conducted to evaluate fluid flow parameters associated with hemolysis risk. The optimized impeller demonstrated a significant increase in low tangential stress zones (&lt;10 Pa), reduced exposure time, and a lower hemolysis index. Comparative mathematical modeling and bench testing with donor blood confirmed the improved hemodynamic performance of the redesigned impeller over the original configuration.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>индекс гемолиза</kwd><kwd>центробежный насос</kwd><kwd>касательные напряжения</kwd><kwd>рабочее колесо</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hemolysis index</kwd><kwd>centrifugal pump</kwd><kwd>tangential stresses</kwd><kwd>impeller</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Itkin GP, Bychnev AS, Kuleshov AP et al.
