Detector of bubbles in blood
Foltýn, Vojtěch ; Sekora, Jiří (referee) ; Rozman, Jiří (advisor)
ABSTRAKT This thesis is the theoretical part deals with various ways of cleansing the blood, with a focus on hem dialysis. Describes the technical solution and monitor the dialysis flow diagram of blood and dialysate. The paper describes various solutions to detect bubbles in the blood and their advantages and disadvantages. Based on the best method of detection are designed detector bubbles. Working in the practical part contains a proposal detector set for venous diameter of 20 mm. Equipment to detect bubbles allows for connection to a blood pump discontinue its activities. Output works are drawing diagrams, printed circuit board design and implementation of graphs circuits.

Design of Dialysis Machine
Zdvihalová, Markéta ; Tvarůžek, Martin (referee) ; Křenek, Ladislav (advisor)
The main aim of this master’s thesis is design of dialysis machine. This thesis should demonstrate author’s creative thinking and creativity. This design has to satisfy the general technical, ergonomic and design assumptions, but it should be designed with modern technology. The aim is also to show the ability to move an object from the field of functionality to the field od aesthetic, ergonimics and practicality.

Design of Dialysis Machine
Zagidullina, Siumbel ; Paliatka, Peter (referee) ; Sládek, Josef (advisor)
The topic of this diploma thesis is the design of a device for dialysis, which is intended for medical institutions. During this thesis existing products were analyzed from the design and technical side. Also was achieved an understanding of the problem of existing dialysis devices. The result is a new conceptual solution with an emphasis on creating clean forms of equipment and taking into ergonomic, technical and aesthetic requirements.

Measurements of permeability of dialysis membranes
Veselá, Martina ; Jiřík, Radovan (referee) ; Kolářová, Jana (advisor)
Familiarization with dialysis theoretical principles and determination of dialysis membrane permeability with the help of experimentally assembled apparatus is the aim of this bachelor thesis. The introduction part deals with basic knowledge concerning treatment with dialysis and its current quality. There continues a chapter stating an overview of dialysis membranes different types and main characteristics of individual materials, which the membranes were made of and which they are produced now. Theoretical preparation for the practical part of the thesis clarifies the basic notions, principals and processes connected with the mass transfer through dialysis membranes and dialysis. Further on, theoretical process is described and phrased how to determine dialysis membranes permeability in a laboratory scale in an experimental way. Two possible configurations of experimental apparatus are illustrated with block schemes working either in a non-stationary or a stationary regime of measurement. The basis to determine membrane permeability is sampling in specified time intervals from blood and dialyze side and spectrophotometric detection of samples concentration. The practical part itself is preceded with the process with collected samples analysis. Then, it is followed with relations derivation for mass transfer coefficient calculation. Concentration progress on blood and dialyze side with non-stationary way of measurement is modelled in Simulink programme. The practical part of the thesis uses the mentioned above theoretical knowledge and assumptions and it realises concrete measurements in non-stationary regime. Evaluating part of the thesis documents the obtained results and assesses them with the help of derived equations. The whole process of measurement including obtained results is evaluated and discussed in the final part.
