Apparatus for the repetitive delivery and discharge of substances for medical therapy, and methods for the production of a stool continency by intermittent colon lavage through a permanently placed, trans-anal occlusion or access catheter

摘要

The invention relates to a device and a method for carrying out a lavage-like, repetitive supply and discharge of a rinsing, cleaning or other therapeutically active substance, in particular in the context of an irrigating emptying of the colon of a patient, wherein the device is a bag - Has / hose unit with combined rinsing and collecting function, which has at least one flußrichtende function, which excludes the immediate return of already derived in the bag rinsing fluid to the patient, and also allows in the bag, the deposition of shaped portions of the already derived rinsing liquid The combination of the bag or tube unit according to the invention with an atraumatic, trans-anally placed catheter unit which preferably seals the anal canal by means of a dumbbell-shaped balloon component makes possible, in particular, large-volume enemas, which almost completely allow complete draining or lavage of the colon without it comes out of the anus during the inlet to the leakage of irrigation fluid. The atraumatic placement of the catheter assembly also allows the catheter to be left in the patient rectum upon completion of the lavage, and removed only after complete evacuation of the colon, thereby avoiding contamination of the patient by subsequent defecation. If the catheter unit is permanently trans-anally positioned, it can be used for an intermittent emptying or lavage, which keeps the descending colon or rectum of stool free, thus allowing the state of a quasi-continence. In the interval between flushes, the catheter assembly placed in the anus ensures a continuous sealing of the anus. It is then completed with a particularly easily built, foil-like, degassing and / or sekretsammelnden element. The connection of the flushing bag / tube unit and the final, degassing units is made by an atraumatic, flat collapsible connector unit, which avoids the formation of pressure points.
