MICRO-POROUS CONDUIT

摘要

A porous conduit may be suitable for use in treating a tissue site, and may include a central lumen and a porous wall positioned substantially concentric about the central lumen. The porous wall may have an open porous structure that may define a plurality of interconnected pores in fluid communication with one another. As part of a system, the porous conduit may be used with a manifold adapted to be positioned at a tissue site, a sealing drape adapted to cover the manifold to provide a sealed space relative to the tissue site, and a therapy device including a reduced-pressure source. The porous conduit may be disposed in the sealed space and in fluid communication between the sealed space and the reduced-pressure source.

1. A system for treating a tissue site, comprising:
a manifold adapted to be positioned proximate the tissue site; a sealing drape adapted to cover the manifold and the tissue site to provide a sealed space between the sealing drape and the tissue site; a porous conduit adapted to be in fluid communication with the manifold and the sealed space, comprising:
a central lumen,a first porous wall substantially concentric about the central lumen, wherein the first porous wall has an open porous structure defining a plurality of interconnected pores in fluid communication with one another,a barrier layer substantially concentric about the first porous wall, wherein the barrier layer is comprised of a non-porous material, anda second porous wall substantially concentric about the barrier layer, wherein the second porous wall has an open porous structure defining a plurality of interconnected pores in fluid communication with one another, and wherein the barrier layer substantially precludes fluid communication laterally between the first porous wall and the second porous wall; and a therapy device adapted to be in fluid communication with the porous conduit.
