Containers for the storage of platelets are made using polyvinyl chloride plasticised with di, (2-ethyl hexyl) phthalate, n-butyryl, tri (n-hexyl) citrate and tri (2-ethyl hexyl) mellitate or using special poly olefins without plasticiser. Of these, the first two have disadvantages such as plasticiser leaching and impairment of platelet function. Polyolefin bags cannot be HF welded or steam sterilized. Mellitate plasticised bags can store platelets well for five days but they are not completely phthalate free. RESEARCH AND DEVELOPMENT: We have developed a new generation of containers made of PVC plasticised with the non DEHP, non aromatic plasticiser,1,2- Cyclohexanedicarboxylic acid, diisononyl ester (Hexamoll DINCH) which can store platelets without loss of function for at least six days.
The present studies show that DINCH plasticised PVC bags (TPL-167) are well suited for the storage of platelet concentrates for more than five days.
The present studies show that the PVC plasticised with the non phthalate, non aromatic, non toxic plasticiser DINCH is a viable alternative to other existing containers for the storage of platelets for more than five days.
储存血小板的容器是用邻苯二甲酸二(2-乙基己基)酯、正丁酰基、柠檬酸三(正己基)酯和偏苯三酸三(2-乙基己基)酯增塑的聚氯乙烯制成,或者使用不含增塑剂的特殊聚烯烃制成。其中,前两种有增塑剂浸出和血小板功能受损等缺点。聚烯烃袋不能进行高频焊接或蒸汽灭菌。偏苯三酸酯增塑袋可以将血小板储存五天,但它们并非完全不含邻苯二甲酸盐。
我们开发了新一代由用非邻苯二甲酸二(2-乙基己基)酯、非芳香族增塑剂1,2-环己烷二甲酸二异壬酯(Hexamoll DINCH)增塑的聚氯乙烯制成的容器,这种容器可以储存血小板至少六天而功能不丧失。
目前的研究表明,用Hexamoll DINCH增塑的聚氯乙烯袋(TPL-167)非常适合储存血小板浓缩物超过五天。
目前的研究表明,用非邻苯二甲酸、非芳香族、无毒增塑剂Hexamoll DINCH增塑的聚氯乙烯是储存血小板超过五天的其他现有容器的可行替代品。
