Rectal Catheter Coupling System for Intestinal Irrigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intestinal irrigation devices are inefficient, hygienic, and dignifying, as they often soil the patient and surroundings, are time-consuming, and require balloons for maintaining catheter placement, leading to discomfort and leakage issues.
Innovation Solution
A novel intestinal irrigation device featuring a rectal catheter with a dimensionally stable structure and a waste collection bag with a coupling system that allows for secure fluid communication and easy disposal, eliminating the need for balloons and minimizing leakage and soiling, with a design that facilitates easy use and manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional transanal irrigation device with an inflatable balloon is used to maintain catheter placement, then the catheter can be fixed inside the rectum, but the patient and surroundings get soiled with irrigated matter and unpleasant smells
Solution Approach 1:
The patent removes the balloon component from the catheter assembly. Instead of using a balloon to maintain catheter placement, the invention uses a collection bag with a coupling part that directly receives the catheter, eliminating the source of soiling and unpleasant smells while maintaining catheter stability through the coupling mechanism
Solution Approach 2:
The patent employs a disposable collection bag with a coupling part that is discarded after a single use. This disposable approach prevents the spread of contamination, eliminates the need for cleaning and sterilization, and ensures that each procedure uses a fresh, clean device, thereby preventing soiling and unpleasant smells while maintaining reliable catheter placement
2Quantity of substance
If a conventional irrigation device with bedpan or absorbent matter is used, then evacuation can be collected, but the procedure is time-consuming and requires washing afterwards
Solution Approach 1:
The patent merges the collection function and the containment function into a single integrated collection bag with a coupling part. The coupling part directly receives the catheter and seals the connection, eliminating the need for separate bedpans or absorbent matter and subsequent cleaning procedures, thereby reducing overall procedure time while maintaining effective evacuation collection
Solution Approach 2:
The disposable collection bag with coupling part is discarded after single use, eliminating the need for washing and sterilization of reusable components. This disposable approach significantly reduces the time required for cleanup and preparation of equipment for the next procedure while maintaining effective evacuation collection
3Ease of manufacture
If a rectal catheter without dimensionally stable structure is used, then the device is simpler to manufacture, but peristaltic movements cause catheter collapse leading to leakage
Solution Approach 1:
The patent applies dimensionally stable structure specifically to the portion of the catheter that is inserted into the rectum and subjected to peristaltic movements. This localized reinforcement ensures the catheter maintains its shape and prevents leakage during bowel movements, while the rest of the catheter and the collection bag can remain simple and easy to manufacture

AI summary
An intestinal irrigation device that includes a waste collection bag and a rectal catheter. The rectal catheter has a first end for coupling with the waste collection bag and a free end for insertion into the rectum, while the waste collection bag has a first wall circumferentially united with an opposing second wall and an inlet opening for irrigated waste. The inlet opening has a first coupling part for coupling the rectal catheter into fluid communication with the bag, and the bag has a second coupling part inside it for mating the first coupling part. The device provides a time saving alternative to known devices, and no odor emissions and unpleasant smell is recognized during the irrigation procedure.
