DEVICE FOR THE REPETITIVE SUPPLY AND DRAINING OF SUBSTANCES FOR MEDICAL THERAPY, AND SYSTEM AND METHOD FOR PRODUCING FAECAL CONTINENCE BY INTERMITTENT COLON LAVAGE BY MEANS OF A PERMANENTLY PLACED TRANS-ANAL OCCLUDING OR ACCESS CATHETER

摘要

The invention relates to a device, a system and a method for carrying out a lavage-like, repetitive supply and draining of a flushing, cleaning or other therapeutically active substance, in particular in the context of an evacuation by irrigation of a patient's colon. The device has a bag unit or bag/hose unit which has a combined flushing and collecting function and also at least one flow-directing function which prevents flushing liquid which has already been drained into the bag from flowing back towards the patient. The invention also relates to the combination of the bag unit or bag/hose unit with a catheter unit which can be placed in position in a permanent and atraumatic manner, is positioned trans-anally, seals off the anal canal, preferably by means of a dumbbell-shaped balloon component, and can be left in the patient's rectum, preferably after lavage is complete.
