1. A colon cleaning device, comprising:

  • an evacuation conduit configured for maneuverability from an anal sphincter at the proximal end of a colon through the curves of a colon to the distal end of said colon, and having a distal receiving aperture configured to receive suction for drawing fecal material from at least a portion of said colon and into a lumen of the evacuation conduit while inserted to said colon; and

    a fluid supply channel, having a supply aperture positioned where a pressure differential between the supply aperture and the evacuation conduit lumen induced by the suction changes upon blockage of said receiving aperture; and

    wherein the supply aperture position is furthermore external to the evacuation conduit lumen, and near a bypass orifice which is separate from the receiving aperture and providing passage of fecal material from at least one other portion of said colon into the evacuation conduit lumen, into which bypass orifice the change in pressure differential elicits the drawing of fluid exiting said supply aperture, such that a pressure differential across said receiving aperture is reduced.
