The invention relates to an antibacterial agent comprising, as active product, a haemostatic contact tissue with an acid pH combined with povidone iodine, the haemostatic contact tissue being regenerated or non-regenerated oxidized cellulose. It also relates to a device used for active protection of incision margins and incorporating such an antibacterial agent. The applicant has now demonstrated surprisingly that the combination of regenerated or non-regenerated oxidized cellulose with povidone iodine provided a degree of bacterial inhibition superior to simple use of regenerated or non-regenerated oxidized cellulose on its own or of povidone iodine on its own. This therefore represents a synergistic effect, which yields a novel agent that is both a very powerful haemostatic and also very powerful antibacterial substance.
L'invention concerne un agent antibactérien comportant comme produit actif un tissu hémostatique de contact ayant un pH acide combiné à de la polyvidone iodée, le tissu hémostatique de contact étant de la cellulose oxydée régénérée ou non ré-générée. Elle concerne également un dispositif de protection actif des berges d'incision intégrant un tel un agent antibactérien. Le demandeur a maintenant mis en évidence de manière surprenante que la combinaison de cellulose oxydée régénérée ou non régénérée avec de la polyvidone iodée donnait une inhibition bactérienne supérieure à la simple utilisation de la cellulose oxydée régénérée ou non régénérée isolée ou de la polyvidone iodée isolée. Il s'agit donc d'un effet synergique qui aboutit à la constitution d'un nouvel agent à la fois hémostatique et antibactérien très puissant.
