Abstract
This application presents methods and devices for continuously cleaning a colon by at least partially filling a segment of the colon with liquid and agitating the fluid to dislodge matter adhering to the colon walls. Methods for automatic maintenance of liquid levels in the colon during continuous cleaning are taught.
Claims45
A device for continuously cleaning a colon comprising:
- a fluid input tube configured for insertion into an anal canal opening and for supplying fluid to a colon segment being cleaned remote from the anal canal opening;
- a material output tube through which liquid and fecal matter may be removed from the colon segment;
- and
- a controller configured to establish and maintain a condition while continuously cleaning, in which said colon segment being cleaned is mostly filled with a mixture of said liquid and said fecal matter;
- wherein said fluid input tube is configured to supply fluid to the colon segment while simultaneously allowing removal of liquid and fecal matter from the colon segments via said material output tube.

A method for cleaning a colon, comprising:
- from an anal canal opening, filling a volume of a segment of the colon remote from the anal canal opening with a liquid to be mostly full;
- agitating a mixture of said liquid and feces;
- inserting additional liquid into the colon segment while simultaneously removing said mixture from the colon segment to maintain a condition in which said colon segment is mostly full;
- and
- emptying said liquid from said segment.

A device for cleaning a colon segment remote from an anal canal opening comprising:
- a) a material output tube through which liquid and fecal matter may be removed, said tube extending from outside the colon to the colon segment;
- and
- b) a fluid flow pulsator configured for insertion into the anal canal opening which supplies alternating pulses of pressurized liquid alternating with pressurized gas, wherein a pressure of said gas is at least 0.2 atmospheres above a pressure of said liquid, and a rate of input of said liquid into the colon segment is at least 400 cc/min;
- wherein said pressure of said liquid is substantially equal to an ambient pressure of a liquid-fecal mixture inside the colon segment;
- and
- wherein the colon segment being cleaned is at least 60% filled with said liquid-fecal mixture.
