The possibility of the hydrodynamic evaluation of bio-pumps with the use of a hybrid-digital model of the circulatory system

Abstract The paper presents a new prototype of a bio-pump which can support a failing heart; the bio-pump is powered by a skeletal muscle. The typical, mechanical system for circulatory support, need external power sources which are not comfortable for patients and cause infection risk. These advantages of biomechanical support systems show that this kind of support has to be developed. A hydrodynamic evaluation of the prototype was carried out with the use of a hybrid-digital model of the circulatory system. The constructed bio-pump prototype improves the values of pressure in the arterial system, eases volumetrically the left ventricle of the heart, and enhances the end-diastolic and end-systolic parameters of the left ventricle. The hybrid-digital model of the circulatory system is a useful tool for a non-invasive evaluation of the systems which can support the circulatory system.
