Benefits of technology

The system reduces the number of flushing cycles, prevents intestinal perforation, and maintains continuous evacuation, ensuring quasi-continence by keeping the colon and rectum clear of feces, minimizing patient soiling and allowing for intermittent lavage over several hours.

Problems solved by technology

However, the previously known design of flushing systems for colorectal irrigation is unsatisfactory in many respects.
The unguaranteed option of long-term positioning of the catheter in the rectum which precludes trauma is problematic in clinical use in this respect, since even though the intestinal contents are mobilized by the irrigation, they are frequently only evacuated in many subsequent fractions following the irrigation.
In addition, when the cycle is repeated multiple times, irrigation liquid increasingly gets into higher sections of the colon, which leads to a further delay in eliminating the mobilized intestinal contents.

Embodiment Construction

[0042]In the context of the invention, FIG. 1 shows an exemplary, single-chamber flushing catheter system 1 for the flow-direction-separated, feces-separating supply of liquid in the patient's rectum or colon as well as for draining mobilized intestinal contents. Located at the forward end of the catheter is a preferably flat, toroidal retention balloon 2, which forms a large-lumen central opening 3 having a diameter of preferably 15 to 30 mm for the intra-rectal reception of liquid or flowable stool. Attached to the anchor balloon towards the proximal is a thin-walled, preferably flatly collapsible tubular film element 4 that integrates two parallel running lumens and connects the part of the device inside the patient to the flushing and collecting bag 5 situated outside of the patient. The lumen 4b supplying the irrigation liquid has a relatively smaller diameter, which reduces or throttles the flow of supplied irrigation liquid in order to prevent irritations from inflow that is ...

Abstract

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.
