Study of diaphragm pump with linear motor
Čejka, Pavel ; Uttendorfský, Petr (referee) ; Pochylý, František (advisor)
The diploma thesis is aimed at the constructional design of diaphragm pumps with a linear motor. This pump is supposed to be used in medicine for pumping the blood or as an artificial heart. The basic facts, which are focused on the function of the heart and artificial heart, are mentioned in the first parts of the thesis. The next parts describe the diaphragm pumps and the constructional ways of their diaphragm fixation. Furthermore, the basic calculations, describing the function of the pump, are derived there. The basic parameters of the pump are also calculated. The thesis also contains the description of the body pump construction, whose working room is optimized by CFD calculation before the pump is manufactured. The final part of the thesis is concentrated on the measurement evaluation of produced pump model.

Design of a model of the human carotid artery based on an electrohydraulic analogy
Škrlová, Nikola ; Kohút, Jiří (referee) ; Jagoš, Jiří (advisor)
The carotid artery plays a crucial role in delivering blood to the cerebral system, which ensures the proper function of the human body. Mathematical models of the cardiovascular system have been proposed to understand vascular disease. The main aim of this study is to create mathematical model of the carotid artery, using an electrohydraulic analogy. The most basic or 0D modeling of cardiovascular system includes the two-element Windkessel model. Numerical modeling was carried out in the MATLAB environment. To make the model solvable, it was necessary to determine the initial flow parameters in the common carotid. It was necessary toadjust the resulting pressure curves on the common carotid to the ideal pressure range of a healthy person. A similar process was performed for the flow in the internal carotid. Then a comparison was made with the real measured flow curve. During the verification of the law of mass conservation of the flow, a 6% deviation was discovered. This discrepancy is attributed to the process of obtaining flow values from the equations assembled in Chapter 5, as well as the rounding error inherent in MATLAB itself. This breakthrough combination of science and medicine is primarily beneficial for doctors and patients who are dealing with the disease.
