Ostomy Pouch with Interconnecting Tube for Oral Intake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ostomates with a percutaneous endoscopic gastrostomy (PEG) tube and esophagus stoma face challenges in consuming food and liquids orally, as anything ingested is immediately discarded through the stoma, limiting their ability to taste and hydrate effectively, and existing ostomy pouches are impractical for everyday use.
Innovation Solution
A system comprising an ostomy pouch with an inlet connected to the esophagus stoma and an outlet connected to an interconnecting tube, which in turn connects to the PEG tube, allowing matter consumed orally to flow into the stomach, enabling ostomates to taste and hydrate while wearing the pouch under clothing without drawing attention to their condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an ostomy pouch is used to collect saliva and discarded matter, then the stoma is managed, but the ability to taste and hydrate orally is lost
Solution Approach 1:
The system segments the ostomy pouch into two functional zones: an upper collection area for saliva and discarded matter, and a lower delivery area for hydrating matter. This segmentation allows the pouch to simultaneously manage stoma waste collection and deliver oral intake to the stomach through the PEG tube, resolving the contradiction between stoma management and oral intake capability.
Solution Approach 2:
The PEG tube acts as an intermediary component that connects the modified ostomy pouch to the stomach. It serves as a dual-purpose conduit: allowing passage of hydrating matter from the pouch to the stomach while maintaining the stoma's function for saliva collection. This intermediary enables both stoma management and oral hydration to occur simultaneously.
2Ease of operation
If a traditional ostomy pouch is used, then stoma waste is collected, but the device is impractical for everyday use and draws attention
Solution Approach 1:
The ostomy pouch is designed with multi-functionality to serve both traditional waste collection and new hydrating matter delivery functions. By incorporating a PEG tube connection and creating distinct upper and lower compartments, the pouch becomes a universal device that handles both saliva/discarded matter collection and oral intake delivery, making it practical for everyday use while maintaining discretion.
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
Enables ostomates to taste and hydrate by allowing ingested liquids and small particulate foods to enter the stomach, improving their quality of life by providing a practical and discreet solution for fluid and nutrient intake.
Implementation Method 1
when the person is in an upright position and the pouch inlet is fixed to the stoma with a major portion of the pouch extending downward, the outlet of the pouch is located below the inlet

AI summary
For a person who has a percutaneous endoscopic gastrostomy (“PEG”) tube and an esophagus stoma, a method for using an ostomy pouch is provided, where inlet of the ostomy pouch is connected to the esophagus stoma and an outlet connected to one end of an interconnecting tube. An opposing end of the interconnecting tube is connected to the PEG tube, so that when the person consumes matter by mouth, the matter flows out the stoma, through the ostomy pouch, the interconnecting tube and the PEG tube, and into the stomach.
