Peristaltic pump control via USB interface
Balogh, Jaroslav ; Chmelař, Milan (referee) ; Čech, Petr (advisor)
The purpose of this bachelor’s thesis is to practical realization of connection between peristaltic pump Rainin Dynamax RP-1 and PC, using USB interface. Integrated circuit device FT232R has been used in USB-RS422 converter, due to modified RS422 interface, which the pump RP-1 uses. There was also developed software for pump’s remote controll. RP-1’s functions can be driven from remote side or eventually automatized with this software. This work is based on semestral thesis and in future can be used in another aplications with RS422 or with RP-1 pump. Department of Biomedical Engineering, attached to FEEC, Brno University of Technology, will use this remote controll in analysis of DNA.

Possibilities of controlling the output characteristics of the peristaltic pump
Odehnal, Martin ; Formánek, Martin (referee) ; Jagoš, Jiří (advisor)
This bachelor's thesis deals with the possibilities of controlling the output characteristics of a peristaltic pump. First, the peristaltic pumps themselves, their design and principles of operation are analyzed. Furthermore, their applications and a description of their use in biomedical applications are described. The main part of this review describes the output characteristics of a peristaltic pump with a follow-up chapter devoted to the possibilities of their control. Here, the options are divided according to their nature into three groups: software, hardware and their combinations. The possibility of variable speed control during the cycle belongs to the category of software control and its implementation is performed in the practical part of this work. This option was chosen due to its universal use, both in the elimination and modulation of pulsation. As part of the work, different schemes were designed that allow variable control of the rotor speed of the stepper motor during one revolution in four modes according to the choice of speed profile.

Dialysis pump
Švagera, Roman ; Rudolf, Pavel (referee) ; Fialová, Simona (advisor)
Dialysis is still very important treatment process today which needs to be constantly improved. This thesis focuses on the development of a pump for dialysis units, specifically on the pressure pulsations reduction in the rotary peristaltic pump. Using experiments, the problem of peristaltic pumps is explained. With the computational modelling there are proposed design modifications leading to the pressure pulsations reduction.

Peristaltic Pump Controll Unit
Charvát, Jakub ; Kopečný, Lukáš (referee) ; Ligocki, Adam (advisor)
The work deals with the problematic of peristaltic pumps and it collects theoretical background information of this topic. The primary goal of the work is the implementation of peristaltic pump and the implementation of protection against equipment damage by overpressure. The overpressure evaluation system in this thesiss on the principle of current measurement of the motor pump. In this work, this premise is successfully tested and applied to the device. Another goal of this work is to create a desktop application that will monitor and control the pump. he data between the application and the device were successfully transfered by the MQTT communication protocol. The communication between the computer and the pump has been tested successfully.

Peristaltic pump
Burda, Radim ; Fialová, Simona (referee) ; Pochylý, František (advisor)
Cílem této diplomové práce je navrhnout peristaltické čerpadlo pro hemodialýzu s ohledem na minimalizaci tlakových pulzací. Pomocí analytické analýzy je navržen nový koncept redukce tlakových pulzací, který využívá zrychlení k navýšení tlaku v prostoru mezi válečky. Fungování peristaltického čerpadla je simulováno pomocí programu Ansys Fluent pro získání lepší představy o proudění v čerpadle. Souběžně s návrhem nového konceptu bylo navrženo více tradiční čerpadlo, které bylo následně vyrobeno a experimentálně odzkoušeno. Data získaná z experimentu mohou být dále použita pro nový koncept.

DESIGN OF AUTOMATIC PIPETTING HEAD ON THE PRINCIPLE OF PERISTALTIC PUMP
Čížek, Petr ; Lang, Stanislav (referee) ; Matoušek, Radomil (advisor)
The aim of this diploma thesis is to design and create a prototype of automatic pipetting head that will be useful for pipetting in laboratories after attaching it to a robotic manipulator. In the beginning, a research about various types of automatic pipetting heads was made followed by a device design and component analysis. The prototype was made using 3D printing method and it utilises a peristaltic pump, Arduino microcontroller and Bluetooth interface. A measurement of repeatability and dispensing accuracy was made on the finished device. The results are evaluated in the conclusion.

Automatic Dosing Unit for Pool Chemistry
Kejík, Jan ; Štůsek, Martin (referee) ; Zeman, Kryštof (advisor)
The objective of this thesis was to design and construct the dosing unit for pool chemistry with the features of common available equipments, but with lower acquisition costs compared to these equipments. The initial part of this thesis describes the requirements for water quality in the pools and the principles of its sustaining. The next section describes the ESP32 microcontroller, which was selected because of sufficient computation power and memory resources and RF connectivity capability. Furthermore, the pH, ORP probes and temperature sensors for measurement of the pool water quality are described in this section. Lastly, sensor convertors, power supplies, pump controls circuit and display interface are described here. The key section of the thesis is the design description which consists of hardware, mechanical and software section. It starts by the description of the printed circuit board with a description of diagram. In the section followed is described and illustrated mechanical design of the box for this dosing equipment. It is my own design made by 3D print. The last design section deals with software consisting of three different kinds of software: display software, ESP32 microcontroller firmware written in C/C++ and HTML code of the webside. This description is focused especially on the firmware architecture of the processor ESP32 related to consecutive part including description of a local user interface as well as a web application. The resulting device was developed to the state with matured well tested user interfaces. However, the controls algorithms of pH and ORP were tested only in simulated conditions. Therefore the testing in real pool for verification of the firmware and reliability should be done in the next steps.

Ballo, Igor ; Marcián, Petr (referee) ; Jagoš, Jiří (advisor)
The focus of this thesis is the design of a peristaltic pump and its subsequent manufacturing using 3D printer. The design was based on a detailed study of constructions of peristaltic pumps focused mainly on applications in biomechanics, from which was proposed an experiment for better understanding the torque required for the pump to operate properly. From this design a prototype was made, the results of experiments brought a new perspective on other designs of peristaltic pumps made by a 3D printer.
