Paper Abstract

The presented research concerns the determination of the pulse discharge volume of an extracorporeal pneumatic heart assist pump. The publication proposes a method for measuring the discharge volume based on the shape of the surface of the flaccid membrane, which is the pressing element of the pump. The membrane shape was obtained using image processing and analysis methods. The effectiveness of the proposed approach has been experimentally verified and confirmed by the authors. However, firm models of flaccid membranes were used in these studies. This work concerns the verification of the operation of the developed method of measuring the discharge volume in close-to-real conditions. For this purpose, an artificial heart chamber model was used along with a designed and produced measuring system. The article presents the laboratory station, the course of the experiment, obtained results and conclusions.
