Stomal Diverter Device with Inflatable Balloon Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ostomy procedures face complications such as leaks, skin irritation, and infections due to the direct attachment of colostomy bags to stoma sites, necessitating an alternative mechanism for collecting fecal matter that improves patient quality of life.
Innovation Solution
A stomal diverter device comprising a catheter with inflatable balloons for anchoring, a stoma rod with adhesive pads for secure attachment, and a bracket for locking the device to the abdomen, allowing for controlled collection and diversion of bodily fluids, reducing complications associated with traditional colostomy bag attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a colostomy bag is directly attached to the stoma site with adhesive, then waste collection is achieved, but skin irritation and leaks occur at the attachment site
Solution Approach 1:
The patent introduces a stomal diverter device as an intermediary component between the stoma and the colostomy bag. This device includes a catheter with tubes that can be inserted into the stoma, a stoma rod that secures to the abdominal wall, and a bracket that locks the components together. This intermediary mechanism eliminates direct adhesive attachment to the stoma site, thereby preventing skin irritation while maintaining reliable waste collection through the drain tube that connects to the colostomy bag.
2Stability of the object's composition
If the stoma is secured to the abdominal wall to prevent withdrawal, then stoma positioning is maintained, but complications such as leaks and infection can still occur
Solution Approach 1:
The stomal diverter device serves as an intermediary system that maintains stoma positioning stability through the stoma rod secured to the abdominal wall and the bracket locking mechanism, while simultaneously preventing leaks and infection by providing a controlled access pathway through the catheter tubes. The device allows for sterile insertion and secure connection to the colostomy bag, reducing the risk of contamination compared to direct adhesive attachment.
3Ease of manufacture
If traditional colostomy bag attachment is used, then waste collection is simple, but patient quality of life is reduced due to complications
Solution Approach 1:
While the stomal diverter device adds components compared to direct attachment, it ultimately simplifies the overall waste collection process by providing a secure, complication-free pathway. The device maintains simplicity through its modular design where the catheter, stoma rod, and bracket work together as an integrated system that is easier to manage long-term than dealing with adhesive-related complications. The drain tube provides straightforward connection to the colostomy bag.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The stomal diverter device effectively secures the stoma, prevents leaks and skin irritation, and allows for obstructing waste flow when needed, enhancing the quality of life for patients by providing a more reliable and comfortable ostomy management system.
Implementation Method 1
The lower surface of the stoma rod includes an adhesive pad configured to attach the stoma rod to the abdomen of the patient.
Implementation Method 2
The inflatable balloon is configured to anchor the first tube to the first body vessel in the inflated position.

AI summary
A stomal diverter device includes a catheter, a stoma rod, and a bracket. The catheter includes a first tube having an open end, a second tube spaced from the first tube having a closed end, and a drain tube. The stoma rod is positioned between the first and second tubes and includes structure to releasably attach the stoma rod to the abdomen of the patient. The bracket is supported on the catheter and the stoma rod and defines a locking feature that is configured to engage a mating feature of the stoma rod to secure the catheter between the stoma rod and the bracket.
