  • Irrigation system
    Patent number: 8231589
    Abstract: An irrigation system includes a control unit and a pump integrated with the control unit. The control unit includes an adjustment knob attached to a major surface of the control unit, a first conduit extending from a side of the control unit to a reservoir that is configured to contain a volume of irrigation liquid, and a second conduit extending from the side of the control unit to an anal probe that is inflatable for fixation of the anal probe within a user. The adjustment knob has a first setting that is selectable to inflate a cuff of the anal probe and a second setting that is selectable to allow the pump to pump gas into the reservoir and thereby transfer the irrigation liquid from the reservoir through the inflated anal probe.
