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.
Claims31
A method for cleaning a colon, comprising:
- inserting a fluid supply pipe into an anal canal opening at least 150 cm into the colon while a proximal end of the fluid supply pipe remains outside the colon;
- supplying fluid to the proximal end of the fluid supply pipe as a mix of liquid segments cyclically alternating with gas segments to be supplied to the colon, wherein said mix of liquid segments cyclically alternating with gas segments includes at least two liquid segments and at least two gas segments located in said fluid supply pipe simultaneously;
- wherein each of the gas segments is compressed in volume between a pair of liquid segments while traveling along the fluid supply pipe;
- wherein said supplying including supplying the mix of alternating liquid and gas segments in sequences in the fluid supply pipe;
- and
- producing pulsed shockwaves of gas segments exiting a distal end of the fluid supply pipe.

A device for cleaning a body cavity comprising:
- a fluid supply pipe, sized for insertion up to at least 170 cm into a body orifice leading to the body cavity while a proximal end of the fluid supply pipe remains outside the body;
- and
- a mixing workstation, fluidically coupled to a proximal side of the fluid supply pipe, and configured to supply fluid for delivery to a segment of the body cavity being cleaned at a distal end of the fluid supply pipe, when the fluid supply pipe is inserted into the body cavity;
- wherein the mixing workstation is configured to generate the flow of supplied fluid as liquid segments cyclically alternating with gas segments, including at least two liquid segments and at least two gas segments located in said fluid supply pipe simultaneously, wherein the mixing workstation is configured to supply the gas segments under compression;
- and
- wherein said mixing workstation is configured to generate the simultaneous flow of the at least two liquid segments and at least two gas segments in sequence in the fluid supply pipe.
3 more elements
A method of cleaning a colon segment of a patient, the method comprising:
- administering into the colon segment a pressurized mixture of gas segments cyclically alternating with liquidd segments, wherein the cyclically alternating gas and liquid segments include at least two liquid segments and at least two gas segments located in the fluid supply pipe simultaneously, wherein the gas segments are compressed in volume while traveling along supply pipe, and wherein said administering includes supplying the mixture of alternating liquid and gas segments in sequence;
- the administering including;
- transferring energy from the pressurized mixture to break down fecal matter in the colon segment, and
- increasing pressure in said colon segment with the administered pressurized mixture;
- sensing the increasing pressure, using a sensor in communication with a controller;
- and
- reducing the increased pressure, in response to commmunication from the sensor, by removal of a portion of the pressurized mixture under control of the controller.
