A device assembly designed for automated or semi-automated irrigation, washing, and evacuation of debris from the colon. It typically consists of a mains electricity (AC-powered) electromechanical unit that includes a pump for infusion of non-medicated fluids (e.g., saline), an extractor (frequently using vacuum), and controls for the temperature and the rate of infusion (e.g., using a nozzle) and withdrawal of the liquid; the system is coupled to dedicated handpieces and/or to disposable catheters introduced through the rectum. It is intended to be used by a healthcare provider in a clinical setting to remove damaged tissue and/or debris (e.g., faeces, foreign objects).
