Visualization of cavitation occurring in an artificial cardio-pulmonary device blood circuit

Abstract

Cavitation occurring in an artificial cardio-pulmonary device blood circuit is reported with a cause of hemolysis. In this study, it is intended to visualize cavitation occurring in an artificial cardio-pulmonary device blood circuit. Visualize cavitation by observing luminescence of the luminol by cavitation. After having circulated luminol solution in a blood circuit, we let a blood circuit occlude using some forceps. Occurring air and luminescence were recorded by using a digital single-lens reflex camera. As a result, we were able to observe the bubbles, but was not able to observe the luminescence. However, it was the experiment using the sonoreactor and was able to observe luminescence in flow. Because luminescence was not observed as for the bubbles occurred in the blood circuit, it was suggested that we did not have energy like acoustic cavitation.
