  • Publication number: 20190290472
    Abstract: An ostomy appliance includes a pouch and a filter construction. The pouch is adapted to collect body waste and has a vent opening provided to allow gas to exit the pouch. The filter construction has a first foil layer secured to a second foil layer to form an enclosure, with a pre-filter inside of the enclosure. The first foil layer and the second foil layer are both liquid and gas impermeable. Multiple gas-inlet holes are formed through one or both of the first foil layer and the second foil layer. A gas-outlet is formed through the second foil layer in communication with the vent opening of the pouch. The filter construction is attached to the pouch only in an area immediately surrounding the vent opening such that a majority of the filter construction is substantially free-hanging relative to the pouch.

  • Patent number: 8905993
    Abstract: An anal irrigation system includes a tube attachable between an anal probe and a container, and a displaceable pump element. The container includes an exterior wall, an inner wall that defines an inside perimeter of the container, and a bridge piece connected between the exterior wall and the inner wall such that a reservoir space is formed between the exterior wall and the inner wall. The inside perimeter of the container provides a containment space within the container that is sized to contain the tube and the anal probe. An opening is formed in the container and communicates with the reservoir space. The reservoir space is configured to contain irrigation liquid. The displaceable pump element is located in the reservoir space, where the displaceable pump element is adapted to increase pressure in the irrigation liquid.

  • Patent number: 8608722
    Abstract: The present invention relates to a container for anal irrigation. In particular it relates to a rigid container which is easy to operate and which easily is transformed from a storage configuration to a ready-to-use configuration. In one aspect the invention relates to a container for an anal irrigation system. The anal irrigation system comprises an anal probe; a reservoir for holding an irrigation liquid (e.g. water); a pump mechanism for pumping a fluid (e.g. air) into the reservoir; and a liquid tube connecting the reservoir with the anal probe. The container comprises an outer chamber wall, defining at least partly the outer dimensions of the container and an inner chamber wall arranged within the outer chamber wall, said outer chamber wall and inner chamber wall defining the reservoir. This provides a reservoir having a small surface area when filled with irrigation liquid. Thus only a low pressure is necessary to evacuate the irrigation liquid from the reservoir and out through the anal probe.
