Apparatus for accomplishing irrigation of the colon and/or other intestinal portions through a stoma including an established path of fluid flow of irrigating liquid from a supply container through a feeding tube into a stoma cone or like structure and further including a peristaltic action monitoring device disposed within the path of fluid flow of irrigating fluid which is structured to indicate, through visual observation, the establishment of peristaltic action in the intestine which tends to reverse the direction of flow of the irrigating fluid and provides proper indication when the flow of the irrigating fluid to the intestine or colon should be stopped.
