Eastman Chemical is introducing Tritan copolyester used in blood management and blood therapy surgical instruments at the Medical Design & Manufacturing West (MD&M West) trade show in California.
Manufacturers can save their money and time by using Eastman Tritan copolyester in blood management and blood therapy surgical devices. This tough Tritan is resistant to chemicals and provides good durability and clarity to blood therapy instruments.
Eastman Tritan copolyester replacing polycarbonate (PC) in blood therapy instruments can reduce processing bottlenecks and enhance the yield while decreasing the overall cost of the system. Manufacturers, who use Tritan in their products, have the capacity of avoiding the secondary annealing phase needed to decrease the possible stress cracking problems, occurring due to PC. The robustness of Tritan is low strains and stress, which occur usually in secondary operations and decreased potential for devices that break in shipping.
Chemical resistance is a significant feature in Tritan copolyester that has allowed the instruments to stay functional and aesthetic after exposure to aggressive disinfectants, lipids and blood. Tritan maintains transparency like glass after the radiation of gamma or electron beam and ethylene oxide gas sterilization. Air bubbles, blood leakage and clotting can be easily identified by the healthcare practitioners, using the device clarity.
Various blood therapy devices, including surgical devices like bubble trap devices, cardioplegia filters, hematological filters, hematological reservoirs and oxygenators, may use Eastman’s Tritan copolyester. This copolyester can be ideally used for blood management devices like centrifugal devices or blood micro filters, blood separation cassettes.
