Detekce úniku krve při nitrožilních zákrocích

Abstract

This thesis tries to find a possible solution to the problem, resulting in exceptional cases in intraaortic balloon counterpulsation. After analyzing the problem and finding a worthy solution for detecting small concentrations of blood mixed with water content in the transparent tube in the first two chapters, optoelectronic detection method is chosen. This principle is described in the third part, which can be considered as the know-how of the entire thesis, 7 complex experimental measurements verified the accuracy. In this section selected the best optoelectronic couple is selected, the ideal setting and the algorithm are chosen to evaluate the content in the tube. The final chapter is a self-designed device, called INKE1, which is able to identify repeatedly the contents in the hose from the air, water and up to 0.1% of blood in the water.
