  • Patent number: 5549587
    Abstract: An ostomy bag having a liquid-gas separation device includes a separator disposed within a flexible film pouch used as an ostomy bag. The separator is made of an absorbent material to collect liquids and separate these components from any gas entering the ostomy bag through the stomal opening thereof. The separator is spaced from a filter incorporated in the ostomy bag to further enhance gas-liquid separation. The separator may be disposed in the bag in an attached or unattached configuration. A perforated wall may be included within the flexible film pouch to minimize clogging of the separator by solids so as to improve and gas-liquid separation. An absorbent pad covers the filter to absorb any fluid surging over the separation and flowing through the filter.
