Abstract
UN MATERIAL ABSORBENTE POROSO QUE CONTIENE UN POLIMERO ABSORBENTE INSOLUBLE E HINCHABLE EN AGUA. EL MATERIAL ABSORBENTE CONTIENE UN POLIETER O UN POLICATION UNIDO AL POLIMERO ABSORBENTE QUE PERMITE UN ANGULO DE CONTACTO CON LA SANGRE EN UNA SUPERFICIE DEL MATERIAL ABSORBENTE DE 0 A 40 GRADOS, APROXIMADAMENTE. DEBIDO A SU HUMECTABILIDAD MEJORADA CON LIQUIDOS, ASI COMO A SU ESTRUCTURA POROSA, EL MATERIAL ABSORBENTE PUEDE PROPORCIONAR UNA MAYOR ABSORCION DE LIQUIDOS Y, EN ESPECIAL, DE SANGRE.
