Development of Artificial Ventricles for Modeling the Cardiovascular System

Resumo

The article presents the results of development and experimental studies of artificial ventricles used for modeling the cardiovascular system. The ventricle is divided into two hemispheres separated by a membrane, ensuring the necessary level of contractility of the artificial ventricle and separating its hydraulic and pneumatic components. The study considered two versions of the ventricle, with mechanical check valves (Vesta Trading, Shcherbinka, Moscow, Russia) and bicuspid artificial valves (ZAO NPP MedEng, Penza, Russia) as aortic and mitral valves. The designed ventricles were compared with a reference, which was represented by a Medos VAD membranous artificial ventricle (Medos Medizintechnik AG, Stolberg, Germany).
