Präsentationen "Dialyse"
Im Modul Artificial Organs II, Master-Studiengang Medizintechnik, haben die Studierenden das Themenfeld "Dialyse" von den medizinischen Grundlagen über die technischen Umsetzungen bishin zu ethischen Fragestellungen kennengelernt. Dabei haben sie sich die Inhalte in Form von Expertenpuzzles angeleitet erarbeitet und in einem interprofessionellen Seminar mit dem FB7 Wirtschaftwissenschaften, Prof. Dr. Basak ethisch diskutiert. Als ein Zwischenergebnis wurden Videos erstellt, um das Prinzip "Dialyse" verständlich und fachlich korrekt zu vermitteln. Diese wurden von den Studierenden des Moduls Business Ethics (Prof. Dr. Basak Canboy, FB7 Wirtschaftswissenschaften) als Vorbereitung zu den Ethik-Sessions genutzt. Hier sind 2 der erstellten Videos zu sehen:

Recording on the heart valve test stand of the cardiotechnology laboratory, Biocor heart valve, 72bpm.
Flow behaviour on a mechanical heart valve (BSMS/K2). The recording was made on the heart valve test stand of the cardiotechnology laboratory using the PIV (Particle Image Velocimetry) measuring system.
Mechanische Herzklappe
Aufnahme am Herzklappenteststand des Kardiotechnik Labors, Herzklappe SJM, 72bpm.
Drive unit of the heart valve test stand using a linear motor. The cylinder and ventricular chamber are filled with fluid.
3D print of an aorta with aortic root. Layer thickness 0.2mm (min. 0.05mm possible), printing time approx. 8 hours.
ECG SPO Tansmitter / Display of measured values and measurement curves / A development of the cardiotechnology laboratory at FH Aachen. Further information here.
ECG isolation measuring amplifier with Arduino microcontroller and TFT touchscreen. Insulation voltage greater than 5.3 kV (patient protection). Construction of the electronic circuit during practical training in medical technology / cardiotechnology as part of the Pacemaker Project.
In the "ECG simulator" practical course, we want to build a simple 1-channel ECG simulator and simulate it using the LTspice circuit simulation software. This is a very inexpensive circuit, component costs less than €5, in which integrated standard components such as the NE555 timer component and two digital logic components from the CMOS 4000 series are used. With a suitable external wiring of the components with R-C elements, an almost signal-faithful sinus rhythm with 60 bpm can be generated. The beat frequency can be increased to 120 bpm using a changeover switch.
As part of a student project (K1 funding), a functional axial blood pump model was successfully developed. The pump is driven by a self-designed brushless DC motor (BLDC). The six windings (A+/A-/B+/B-/C+/C-) on the stator of the motor were wound by hand. The rotor blades were produced using 3D printing and are equipped with permanent magnets. Transferring electrical energy to the rotor inside the motor is not necessary with this configuration. The motor is controlled by an electronic 3-phase commutation, which also realises the speed control. The motor controller used for this purpose requires three Hall sensors (HA/HB/HC) for rotor position detection, which are positioned at 120° intervals on the stator. The axial blood pump is equipped with a magnetic bearing on the right-hand side.
