| Abstract: | In this research, polyurethane's hard segments modified ventricular assistant device of blood compatibility and toxicology characteristics were evaluated using hemolysis test,the dynamic cruor time test,the adhesion of blood platelet test, and systemic injection test. The results show modified polyurethane's is better in blood compatibility than that without modified polyurethane's, Modified polyurethane's does not have significant toxicology. |
