  • Patent number: 6050983
    Abstract: A colostomy container that is worn by individuals who are in need of a means of passing feces and urine. The container isolates flatus from fecal matter and is capable of containing both excrement elements in separate chambers. Particularly, the stool is collected in a bottom chamber that is disposable, and a spring actuated ball check prohibits reverse flow of fecal matter back into the stoma. The flatus is collected in a top chamber where it is deodorized with a graphite filter and vented. The center of the container is insulated with foam to reduce noise resulting from waste products exiting the stoma and entering the container.
