Grundlagen der Quantenmechanik,two of the cases, weaning could not be performed because of continued bleeding, and the other patient is still alive. No gross findings of thrombus formation were observed in any of the cases, except for a thin circular thrombus at the junction of the connectors and the sack of the blood pump.commute 发表于 2025-3-28 01:21:15
Blood material interactions: Ex vivo investigations of polyurethanesaluation of up to ten different materials simultaneously. Deposition of radiolabeled platelets and fibrinogen is quantified and used as a measure of thrombogenicity. The canine ex vivo experiment has been implemented in investigations of the roles of many aspects of polymer surface chemistry in platDebark 发表于 2025-3-28 05:03:37
Mechanical properties of segmented polyether polyurethanes for blood pump applications, and 5 Hz) on the fatigue properties of Biomer and Toyobo TM5 polyurethanes were studied to obtain basic data for the design of artificial heart pumps and for the development of accelerated endurance test methods..The mechanical properties of these materials deteriorated more significantly followin雪崩 发表于 2025-3-28 09:31:55
Effect of segment structure on fatigue behavior of segmented polyurethaneureas in pseudobiological ey means of differential scanning calorimetry. After immersing in a lipid solution, the specimen showed a weight increase due to sorption of lipids. Acceleration of lipid sorption was observed under cyclic straining. Dynamic viscoelastic measurements revealed that the disordered hard segment lost itsGNAW 发表于 2025-3-28 13:44:24
