Automation of a test bench for measuring blood damage in heart pumps
The goal is to automate testing of blood damage in heart pumps. The project includes Investigating electrical conductivity of blood and changes with blood damage and building and validating new automated test bench with commerical heart pumps.
Keywords: Heart pumps, blood pumps, Zurich Heart, Biomedical engineering, Medical application, Medicine, in vitro testing, product development, prototyping
Testing of blood damage is a crucial step in the development of next generation blood pumps. The tests are usually performed with recirculating animal blood in the laboratoy. Blood damage is currently assessed by measuring the change in color of the blood plasma. Many sample preparation steps limit the total number of samples that can be taken by the experimenter. Recent research indicates that electrical conductivity measurements could be a much easier and automatable way to observe relative changes of blood damage. In this project this new approach should be explored and compared to the current gold standard.
