Abstract
Systems and methods for cleaning a colon or other portion of an intestine include optional use of sensors to detect conditions of blockage of flow of materials within an evacuation channel used to remove fecal material from the body; and devices and methods for purging such blockages from the evacuation channel.
Claims18
A colonoscope add-on system comprising:
- at least one bidirectional pressure source operable to supply distally directed pressure or proximally directed pressure;
- an add-on tube assembly comprising at least a first channel and a second channel in which flow is independently controlled by supplying pressure from said at least one bidirectional pressure source;
- and
- a controller configured to coordinate operation of said first channel and said second channel by selecting any one of the following operation modes:
- (a) a mode in which distally directed pressure is supplied through said first channel for purging and/or irrigating, and proximally directed pressure is supplied through said second channel for evacuating matter from the colon;
- (b) a mode in which distally directed pressure is supplied through said second channel for purging and/or irrigating, and proximally directed pressure is supplied through said first channel for evacuating matter from the colon;
- and
- (c) a mode in which proximally directed pressure is supplied through both said first channel and said second channel for evacuating matter from the colon at a higher rate.
A method of operating an add-on tube assembly used with a colonoscope, the add-on tube assembly comprising at least first and second channels in which flow is independently controlled, the method comprising:
- introducing said add-on tube assembly alongside a colonoscope insertion tube into a colon;
- controlling, via a controller, an operation mode of said first channel and said second channel, said operation mode selected from any one of the following operation modes:
- (a) a mode in which distally directed pressure is supplied through said first channel for purging and/or irrigating, and proximally directed pressure is supplied through said second channel for evacuating matter from the colon;
- (b) a mode in which distally directed pressure is supplied through said second channel for purging and/or irrigating, and proximally directed pressure is supplied through said first channel for evacuating matter from the colon;
- and
- (c) a mode in which proximally directed pressure is supplied through both said first channel and said second channel for evacuating matter from the colon at a higher rate.
