A device assembly designed for automated or semi-automated irrigation, washing, and evacuation of debris (e.g., toxic substances) from the stomach. It typically consists of a mains electricity (AC-powered) electromechanical unit that includes a pump for infusion of non-medicated liquid (e.g., saline); an extractor (frequently using vacuum) and controls for liquid temperature/pressure and rate of liquid infusion/withdrawal; and bags for the irrigation solution and waste. Most systems can deliver charcoal to the stomach for absorption of toxic substances; they are mainly used in emergency departments and for cleaning/evacuation of the stomach before some endoscopic and/or surgical procedures.
