Цель работы — исследовать возможность моделирования физиологического здорового состояния и состояния сердечной недостаточности в стенде, моделирующем большой круг кровообращения, а также в стенде сердечно-сосудистой системы с имплантируемым аппаратом вспомогательного кровообращения.
С развитием медицины и технологий альтернативой пересадке сердца на терминальных стадиях сердечной недостаточности становится установка аппаратов вспомогательного кровообращения (АВК), поддерживающих насосную функцию сердца. Для разработки, совершенствования и проведения испытаний АВК разработан стенд сердечно-сосудистой системы, позволяющий воспроизводить различные состояния физиологической сердечно-сосудистой системы.
Для различных видов исследований существует возможность использования стенда в нескольких конфигурациях: стенд большого круга кровообращения, стенд сердечно-сосудистой системы, стенд большого круга кровообращения с подключением системы вспомогательного кровообращения, стенд сердечно-сосудистой системы с подключением системы вспомогательного кровообращения.
С учётом того, что проблема сердечной недостаточности в первую очередь связана в левым желудочком, было принято решение исследовать возможность моделирования физиологических параметров в стенде, моделирующем большой круг кровообращения. были проведены исследования: принципа пропорциональности изменения объема и давления; закона Франка-Старлинга зависимости силы сокращения от силы растяжения сердечной мышцы; принципа сопротивления кровеносной системы потоку крови.
В стенде сердечно-сосудистой системы были проведены исследования интеграции в систему: АВК левого желудочка; АВК правого желудочка; АВК левого и правого желудочков одновременно.
Результаты исследований показали, что стенд сердечно-сосудистой системы позволяет моделировать физиологические параметры и может быть использован для проведения доклинических испытаний АВК. Полученные в ходе работы результаты будут являться основой для проведения дальнейших исследований в области проектирования стендов сердечно-сосудистой системы и проведения испытаний АВК.

Abstract
Study of the problems of modeling of physiological parameters in the stands of the cardiovascular system

Amount: * Home * pattern * table, * source.
Keywords: STAND OF CARDIOVASCULAR SYSTEM SIMULATION physiological parameters LAW Starling, heart failure, aPPARATUS circulatory support
Objective - to explore the possibility of modeling physiological health status and condition of heart failure in the stand, simulating the systemic circulation, as well as the stand of the cardiovascular system with an implantable device circulatory support.
with the development of medicine and technology alternative to a heart transplant in the terminal stages of heart failure becomes installation circulatory support devices (AVC) supporting the pumping function of the heart. In order to develop, improve and conduct AVK tests designed stand of the cardiovascular system, allows you to play a variety of state of the physiological cardiovascular system.
For different types of research it is possible to use the stand in several configurations: stand the systemic circulation, stand the cardiovascular system, stand large circulation connecting auxiliary circulatory system, the stand of the cardiovascular system with a connection system circulatory support.
Given the fact that the problem of heart failure is primarily due to the left ventricle, it was decided to explore the possibility of modeling of physiological parameters in the stand, simulating the systemic circulation . studies were carried out: the principle of proportionality of the change in volume and pressure; Frank-Starling law, depending on the force of contraction of the stretching force of the heart muscle; . Resistance principle of the circulatory system of blood flow
integration studies have been conducted in the stand of the cardiovascular system in: AVK left ventricle; AVK right ventricle; AVK left and right ventricles simultaneously.
The results showed that the stand of the cardiovascular system can simulate the physiological parameters and can be used for preclinical testing of AVC. The findings of the results of work will be the basis for further research in the field of design stands the cardiovascular system and of the AVK tests.
