El soporte per-absorbente 31 se dimensiona y se moldea para stancialmente sobre la herida lineal 12 y, si se a aplicación de área, el soporte de apósi sorbente 31 se dimensiona para acoplarse sustanci ea estimada de tejido subcutáneo dañado 20 au ilizarse un tamaño más grande o más pequeño en ireaciones . La capa super-absorbente 32 se icionalmente más adelante.
"Ventilable" como se utiliza^ en la gnifica permeable al gas. La capa seca
tilable restringida al fluido es análoga a la ñal desechable típico que se encuentra próxima a bebé.
El soporte de aposito super-absorben erable para distribuir la presión reducida a neal 12 y desarrollar fuerzas. El término "dis o se utiliza en la presente, se refiere en gen stancia o estructura que se proporciona para licar presión reducida a, suministrar fluidos a, uidos de, un sitio de tejido. Un material di cluye típicamente una pluralidad de canales o vía e se interconectan para mejorar la distribuci uidos proporcionados a y retirados de el área rededor del distribuidor.
El subsistema de sellado 60 incluye irúrgico 62, o miembro de sellado. El paño qui ede ser cualquier material que proporcione un se

Aunque los términos resión negativa" pueden utilizarse para des esión aplicada al sitio de tejido, la presión rea sitio de tejido puede ser mayor que la presión n ociada con un vacio completo. Consistente con el esente, un incremento en la presión reducida o cio se refiere típicamente a una reducción rela esión absoluta.
A fin de maximizar la movilidad y com ciente, la fuente de presión reducida 82 pue erador de presión reducida energizado por bate

La naturaleza super-absorbente del s ósito super-absorbente 31 permite la posib ilizar una fuente de presión reducida que no r cipiente de almacenamiento de fluido remoto debid porte de aposito super-absorbente 31 almacena el era efectiva. La capa super-absorbente 32 pued 0 mililitros de fluido o más. Al mismo tiempo, trada 38 mantiene el fluido alejado de la epider ciente de manera que puede evitarse la macera ente de presión reducida 82 se muestra con un cor batería 84. Un filtro de membrana intercalado, filtro hidrófobo u oleófobo, puede extenderse nducto o tubería de suministro de presión reduci ente de presión reducida 82.
una porción interior del subsistema de sellad ta modalidad particular, la interfaz de presión r extiende a través del paño quirúrgico 62 y porte de aposito super-absorbente 31.
En operación, el sistema de tratamiento ducida 10 puede aplicarse en la sala de operacion un procedimiento quirúrgico en el paciente o en ra parte.

Durante el tratamiento, se tiene cuidado irritación de la piel, tal como la formación d la epidermis 14 del paciente, debido al corte s rantez secundaria u otros efectos. Para ayudar a ritación de la piel, el reborde periférico ldearse o angularse o puede agregarse una ca tre el soporte de aposito super-absorbente idermis 14 del paciente.
Ahora con referencia a la Figura 2, se rte transversal esquemático despiezado de una por spositivo de aposito super-absorbente 130 para sistema de presión reducida para tratamiento d dispositivo de aposito super-absorbente 130 es
per-absorbente 132, una capa de entrada 138, y perior 144.
La capa de entrada biene una primera 0 y una segunda superficie 142 orientada hacia el capa de entrada 138 se destir.a a permitir que andone la herida lineal 112 en la epidermis 14 de pase a través de la capa de entrada 138, pero no la epidermis 114. En otras palabras, la capa 8 funciona para permitir de manera efectiva el fl dirección. Esta acción una via ayuda a ceración de la epidermis 11 . .a capa de entrada mbién a manejar o distribuir la presión redu rida lineal 112. La capa de entrada 138 puede d mo una capa seca ventilable. Pueden utiliza teriales para la capa de entrada 138 tales como drófilo no tejido.
La capa superior 144 tiene una primera
película de polietileno ayudará a que teen. En una modalidad alternativa, la capa su ede omitirse y utilizar solo un paño quirúr tener los fluidos dentro del dispositivo de após sorbente 130.
Puede agregarse una capa ventilable de icional sobre la primera superficie 146 de la cap 4 para funcionar como un filtro. La capa ven terfaz 194 cubre la abertura 149. La capa ven terfaz 194 permite el suministro de presión ita que las porciones de la capa super-abso tren a la interfaz de presión reducida, e.g., l presión reducida 92 de la Figura 1, que desca rte superior del dispositivo de aposito super-0.

A fin de permitir el uso de un ducida sin un recipiente remoto o con un recipie lativamente pequeño en un paciente humano, es dés chas aplicaciones quirúrgicas, producir la ca sorbente 132 operable para contener al menos 300 fluido. En algunas aplicaciones, adicionalmente seable proporcionar un material super-absorbe nducto de suministro de presión reducida (e.g., gura 1) entre el aposito super-absorbente 132 y presión reducida para contener el fluido adicion
