Abstract
CAPAZ DE ABSORBER SANGRE Y FLUIDOS BASADOS EN SANGRE TENIENDO UNA ESTRUCTURA DE ESPUMA POLIMERICA NO IONICA, HIDROFILA Y FLEXIBLE DE CELDAS ABIERTAS INTERCONECTADAS CON UN NUMERO PROMEDIO DE TAMANO ENTRE 20um y 180um; Y UN NUMERO PROMEDIO DE TAMANO DE CAVIDAD ENTRE 4um y 180um; DONDE LA ESTRUCTURA DE ESPUMA SE CARACTERIZA POR: I) LA CAPACIDAD DE FILTRAR FLUIDO MENSTRUAL ARTIFICIAL VERTICALMENTE A UNA ALTURA DE 5cm EN MENOS DE 60 MINUTOS; II) UN AREA DE SUPERFICIE ESPECIFICA DE CAPILARIDAD EN EL ORDEN DE 0,0080m/cm3 ENTRE 0,040m/cm3; III) UNA RESISTENCIA A LA DESVIACION POR COMPRESION ENTRE 5% Y 95% CUANDO SE MIDE BAJO UNA PRESION LIMITANTE DE 0,74psi A 31�C DESPUES DE 15 MINUTOS;IV) UNA CAPACIDAD LIBRE ABSORBENTE ENTRE 20g/g y 125g/g; V) APROXIMADAMENTE 2% DE SALES RESIDUALES HIDRATABLES. UNA ALMOHADILLA CATAMENIAL COMPUESTA DE: a) UNA LAMINA SUPERIOR PERMEABLE AL FLUIDO; b) UNA LAMINA INFERIOR; Y c) UN NUCLEO ABSORBENTE COLOCADO ENTRE LA LAMINA SUPERIOR Y LA LAMINA INFERIOR Y LA REGION DE DESCARGA DEL FLUIDO. SE UTILIZA EN ARTICULOS ABSORBENTES DESECHABLESABLE TO ABSORB BLOOD AND BLOOD BASED FLUIDS HAVING A NON-IONIC, HYDROPHILIC AND FLEXIBLE OPEN CELL FOAM STRUCTURE INTERCONNECTED WITH AN AVERAGE NUMBER OF SIZES BETWEEN 20um and 180um; AND AN AVERAGE NUMBER OF CAVITY SIZE BETWEEN 4um and 180um; WHERE THE FOAM STRUCTURE IS CHARACTERIZED BY: I) THE CAPACITY TO FILTER ARTIFICIAL MENSTRUAL FLUID VERTICALLY AT A HEIGHT OF 5cm IN LESS THAN 60 MINUTES; II) A SPECIFIC SURFACE AREA OF CAPILLARITY IN THE ORDER OF 0.0080m / cm3 BETWEEN 0.040m / cm3; III) A COMPRESSION DEVIATION RESISTANCE BETWEEN 5% AND 95% WHEN MEASURED UNDER A LIMITING PRESSURE OF 0.74psi AT 31�C AFTER 15 MINUTES; IV) AN ABSORBENT FREE CAPACITY BETWEEN 20g / g and 125g / g; V) APPROXIMATELY 2% OF HYDRATABLE RESIDUAL SALTS. A CATAMENIAL PILLOW COMPOSED OF: a) A FLUID PERMEABLE UPPER SHEET; b) A LOWER SHEET; AND c) AN ABSORBENT NUCLEUS PLACED BETWEEN THE UPPER SHEET AND THE LOWER SHEET AND THE FLUID DISCHARGE REGION. IT IS USED IN DISPOSABLE ABSORBENT ITEMS
