Avaliação de bolsas plásticas utilizadas para acondicionamento de sangue e hemocomponentes.

Abstract

This research has the objective the physical chemical, morphological and structural evaluation of Polyvinyl Chloride (PVC) bags for blood filling and hemocomponentes. The samples from national and imported blood bags used for this research were selected through ANVISA database from blood bags regularly released by that. The PVC blood bags were characterized by Fourier transform Infrared (FTIR), X-ray Diffraction (XRD), optical microscopy (OM), scanning electron microscopy (SEM), energy dispersed spectroscopy X-ray (EDS), Atomic Force Microscopy (AFM) and Mechanical Testing. The analyses were performed on Biomaterial development and evaluation lab (CERTBIO). On Fourier transform Infrared (FTIR) it was observed that all components show chemical similarity. On XRD was noticed that the samples have showed a semi crystalline characteristics. On OM and SEM it was noticed that the sample has a smooth side and other with sprinkles on surface. ON EDS assay it was observed conformity on chemical compounds identified as well as on their strength. It demonstrates that blood bags follow the same composition criteria. Based on mechanical tests results for both manufacturers, the blood bags without anticoagulant showed less deformation compared to blood bags with anticoagulant. All bags showed viscoelastic material behavior. Thus, we can conclude that all characterization tests used in this study were relevant to assessing the quality of the bags that are used as containers of blood and its components existing on the market, considering the general and specific requirements established in rules and regulations.
