Artificial heart on the principle of gas accumulators
Kunický, Ondřej ; Fialová, Simona (referee) ; Pochylý, František (advisor)
The diploma thesis deals with the design of an artificial heart based on the principle of gas accumulators. The introductory part describes the anatomy and physiology of the human cardiovascular system, mechanical heart replacement and the basic properties of pneumatic mechanisms. Furthermore, there is shown the procedure of pneumatic circuit design and its simulation in the program Simulink. The experimental part contains verification of the functionality of the pneumatic circuit, designed the positive displacement pump, and the measured characteristics of both ventricles. The last part of the work deals with the reduction possibilities of dimensions and weight of the whole mechanism. There is also included computational modelling of the pneumatic circuit using helium as a working medium.

Modification of a blood pump as a heart replacement
Simandl, Mirek ; Fialová, Simona (referee) ; Pochylý, František (advisor)
The master’s thesis deals optimization of regenerative pump and axial pump with ring motors that are designed as a heart replacement. Analysis of the koncepts is performed which were made in previous master’s thesis. There is created a new design of construction and hydraulition with using flat motors based on the analysis. The compact assembly of two impeller was formulated that replaced left and right heart and it served as a function of heart replacement. A functional model of the pump is created, there is measured characteristics of impeller and results are compared with CFD analysis. The design requirements some parts of the axial pump are added and it’s deviced feasibility analysis.
