[Experimental study of the relationship of the level of blood hemolysis and the design of artificial heart valves].

Abstract

The paper deals with experimental studies into the level of hemolysis that accompanies the performance of artificial cardiac valves (ACV). The studies were conducted by two ways. The first study determined the level of hemolysis when artificial cardiac valves worked and donor blood performed. The second one was that a polymer was added to the model physiological fluid, the degree of hemolysis was determined by the changes occurring in the time of relaxation of elastic stress in the model fluid samples taken during tests. The experiments showed polyethylene oxide break-down to be the most accurately modelling process of hemolysis.
