Abstract
Disclosed are irrigation systems and methods, which can be used for rectal/anal irrigation. One example system includes a reservoir for an irrigating liquid, a probe for arrangement in a user, tubing providing fluid communication between the reservoir and probe, and an electrical pump for indirectly pumping irrigation liquid from the reservoir to the probe through said tubing. The electrical pump is controllable to assume a plurality of predetermined flow rates. The system includes an electrically operable valve to continuously control a degree of openness of the tubing, a flow sensor to measure an actual flow rate of the irrigation liquid in the probe, and a controller to obtain a desired flow rate, and control the flow rate of the electric pump to one of the plurality of flow rates exceeding the desired flow rate, and to continuously regulate the electrically operable valve based on the measured actual flow rate.
