  • Patent number: 5705251
    Abstract: A multi-layered structure having improved liquid barrier properties is provided. The multi-layered structure includes a porous hydrophobic layer and a spacing layer adjacent to and in juxtaposition with the porous hydrophobic layer. The function of the spacing layer is to provide sufficient channels for a liquid while supporting all or substantially all of a compressive pressure exerted against the spacing layer. As such, when the spacing layer is contacted with a liquid, such as water, saline or a bodily fluid such as blood, and subjected to a compressive pressure, of at least 2 psi, applied generally perpendicularly to the spacing layer, the channels are available within the bulk of the spacing layer for such liquid to flow therein or therebetween, while all or substantially all of the compressive pressure is supported by the spacing layer. In this way, the liquid in contact with the spacing layer flows into these channels without passing through the porous hydrophobic layer.
