RESUMO
The work explored the DEHP migration parameters in PVC infusion in clinic,based on the previous research on the test model of DEHP migrated from PVC infusion,to assess the safety of PVC infusion.The leaching solution samples in different conditions were evaluated by analysis of the DEHP in leaching solution using GC-MS under simulated clinical transfusion way.The release behavior of DEHP was significantly affected by the storage time,storage temperature,surrounding temperature,dripping speed,sterilization process,volume of the leaching solution,and the property of the leaching solution.

As we all know, DEHP is seriously harmful to human health and consequently has been acquired critical attention. DEHP is able to migrate from PVC medical devices for the non-chemically bound to PVC, thus contact with user and patient. The DEHP migration is influenced by various parameters. In order to assess the security of PVC-tubes medical devices scientifically of DEHP migration, we develop an experimental model by analyzing the parameters comprehensively and systematically, taking into account the clinical practices. For example, assessing the security of DEHP migration from infusion sets by utilizing this model.
