Abstract

Se describen métodos de obtención de vendajes para heridas que incluyen los pasos de proveer una solución de un polímero biocompatible soluble en agua o hinchable en agua disuelto en un solvente para el polímero, proveer un sustrato de tela que tiene una primera superficie y una segunda superficie opuesta a la primera superficie, teniendo dicha tela propiedades efectivas para utilizar como hemostato y conteniendo fibras preparadas a partir de un polímero biocompatible, poner en contacto el sustrato de tela con la solución de polímero en condiciones efectivas para distribuir la solución de polímero en forma sustancialmente homogénea sobre la primera y segunda superficies y a través del sustrato de tela, transferir el sustrato de tela que tiene la solución de polímero distribuida en forma sustancialmente homogénea a través de la misma a una unidad de liofilización en condiciones efectivas para mantener la distribución homogénea sobre y a lo largo del sustrato, y liofilizar la tela que tiene la solución de polímero distribuida a través de la misma, proveyendo por ello una matriz polimérica porosa distribuida en forma sustancialmente homogénea sobre la primera y segunda superficies y a través de la tela, estando la matriz elaborada con el polímero liofilizado soluble en agua o hinchable en agua.
