  • Patent number: 9033944
    Abstract: An ostomy pouch apparatus including a first and second sheets of flexible sheet material having perimeter edge portions and respective broad surface portions, the first and second sheets joined at the perimeter edge portions to form a pouch having an interior portion between the first and second sheets. The apparatus includes a waste admitting opening on the broad surface portion of the first sheet for admitting and subsequently removing a waste holding bag disposed within the interior portion of the pouch, and a coupling disposed about the waste admitting opening for connecting to a flange secured to a waste releasing opening on a patient.

  • Patent number: 5423782
    Abstract: A disposable ostomy bag liner apparatus including a unitary flexible bag having a main body portion, a tapered portion, a narrowed portion and a flange portion. The tapered portion is disposed adjacent the main body portion and together, the main body portion and tapered portion define an interior portion of the bag for receiving and hold intestinal waste material. The narrowed portion is disposed adjacent the tapered portion and is for holding the bag in place during insertion of the bag in an opening of a bag flange of a conventional ostomy bag. The narrowed portion defines a mouth opening in the bag for admitting intestinal waste material into the interior portion. The flange portion is adjacent the narrowed portion, and cooperates with the bag flange to secure and seal the liner to an ostomy flange on the patient.
