An interactive mechanical simulation of the cardiovascular system facilitates measuring cardiovascular function and disorders.
As part of the TRANSFORM initiative, we developed a model representing the hydraulic simulation of the cardiovascular system that has the technical capability to replicate various clinical scenarios. The model was used as part of the mandatory course “Praktikum Alterung II” for med students in the 4th semester of med studies at the JKU. Student feedback of the course is consistently positive. We are currently searching for funding opportunities to reproduce the enhanced prototype (in at least two versions) to use permanently for courses taught at the Faculty of Medicine.
A Description of the Model.
The cardiac model is based on the publication ‘A Hydraulic Model of Cardiovascular Physiology and Pathophysiology Embedded into a Computer-based Teaching System for Student Training in Laboratory Courses’, opens an external URL in a new window and is simulated by means of a linear motor and flexible membrane. The Windkessel aortic function is simulated by means of a flexible bellow which can be adjusted, and a needle valve is used to simulate the peripheral resistance. By manipulating the motor, the aorta, the peripheral resistance, and the heart valves, the model is capable of simulating various pathophysiological states. Based on its practical applications, we were able to adapt the model to create additional options for use, including kidney function simulation and expanded vascular function. The enhanced model is now being tested and, once testing is completed, the results are expected to be published in medical journals.

Course.
The first prototype was used as part of the physiology course ‘Praktikum Alterung II’ at the JKU on June 20, 2024. Over 200 students attended this mandatory course. Under the supervision of tutors and instructors, small groups of 15 to 30 students used the model for an hour for practice purposes. The groups were presented with various pathological scenarios, including systolic and diastolic heart failure, central and peripheral hypertension, and aortic valve disease. The students analyzed the respective clinical conditions and subsequently demonstrated these conditions by using the model.
