Beschreibung
Zusammenfassung:	The invention relates to a biodegradable non-woven material containing (i) at least one polymer for inducing primary haemostasis, (ii) at least one non-proteinogenic, water-soluble secondary haemostasis activator having a low molecular weight, and (iii) at least one non-proteinogenic, water-soluble fibrinolysis inhibitor having a low molecular weight. The invention also relates to a method for producing a biodegradable non-woven material, wherein (i) a fluidised raw fibre material is placed in a container, optionally along with additives, (ii) the container is set in rotation, (iii) the fluidised raw fibre material is discharged from the container by means of centrifugal forces, as a result of which fibres or filaments are formed, and (iv) a biodegradable non-woven material is formed from the fibres or filaments. The invention also relates to the use of such a biodegradable non-woven material as a local haemostatic agent. L'invention concerne un non-tissé biodégradable, contenant (i) au moins un polymère destiné à induire l'hémostase primaire, (ii) au moins un activateur de l'hémostase secondaire non protéinogène, de faible masse moléculaire et soluble dans l'eau, et (iii) au moins un inhibiteur de la fibrinolyse non protéinogène, de faible masse moléculaire et soluble dans l'eau. L'invention concerne également un procédé de fabrication d'un non-tissé biodégradable dans lequel (i) un matériau brut fibreux fluidisé est introduit dans un récipient, le cas échéant avec des additifs, (ii) le récipient est mis en rotation, (iii) le matériau brut fibreux fluidisé est extrait du récipient sous l'action de forces centrifuges, formant ainsi des fibres ou des filaments, et (iv) un non-tissé biodégradable est formé à partir de ces fibres ou filaments. L'invention concerne en outre l'utilisation d'un tel non-tissé biodégradable comme hémostyptique local.
