ABSTRACT:
This invention concerns an absorbent pad which is particularly useful for absorbing body fluids. The absorbent pad comprises a fluid-absorbent fibrous layer having a central portion and a peripheral portion, and a flexible fluid-pervious covering sheet for covering at least one side of the fibrous layer. A first wicking means is provided, conveniently by embossing, in the fibrous layer to conduct fluid outwardly from the central portion towards the peripheray of the fibrous layer. A second wicking means is in fluid conductivity with the first wicking means and conducts fluid from the first wicking means in a direction away from the first wicking means. Generally, the second wicking means conducts fluid around, but spaced from the periphery of the fibrous layer. A liquid-impervious, vapor permeable backing sheet can be provided. Helical or radial paths may be utilized for the wicking means.
