Abstract

La surface du verre est modifiée en greffant chimiquement, au moyen de ponts moléculaires, des chaînes de polyamide-amine capables de former un complexe avec l'héparine et, en conséquence, de fixer celle-ci de manière stable, la surface du verre modifiée chimiquement de cette manière étant ensuite traitée avec une solution d'héparine. Ce procédé permet d'éliminer le caractère thrombogène du verre, le rendant ainsi propre, non seulement à la fabrication de récipients pour le sang ou le plasma, mais aussi à une utilisation comme élément constituant de prothèses artificielles ou de protections médico-chirurgicales.The surface of the glass is modified by chemically grafting, by means of molecular bridges, polyamide-amine chains capable of forming a complex with heparin and, consequently, of fixing the latter in a stable manner, the surface of the modified glass chemically in this manner then being treated with a heparin solution. This process makes it possible to eliminate the thrombogenic character of the glass, thus making it suitable, not only for the manufacture of blood or plasma containers, but also for use as a constituent element of artificial prostheses or medico-surgical protections.
