Ostomy Pouch Replacement Device With Segmented Absorbent Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy pouch replacement devices do not effectively collect, contain, and dispose of both urine and excrement, often requiring preassembly and not being customizable to individual stoma diameters, leading to potential leakage and infection risks during the replacement process.
Innovation Solution
A customizable ostomy pouch replacement device with a dual absorbency chamber and disposable waste receptacle, featuring an absorbent member with varying levels of absorbency and a superabsorbent polymer gel, along with a reusable alignment sleeve, cap, and collar stand for secure attachment and disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single absorbent material is used in existing ostomy pouch replacement devices, then the device structure is simple, but it cannot effectively absorb both urine and excrement with different absorbency requirements
Solution Approach 1:
The absorbent member is divided into a first absorbent portion and a second absorbent portion with different absorbency levels. The first portion (closer to stoma) has lower absorbency for urine, while the second portion (distal end) has higher absorbency for excrement. This segmentation allows each portion to be optimized for its specific function, effectively resolving the contradiction between reliability and device complexity.
Solution Approach 2:
Different regions of the absorbent member are assigned different absorbent properties. The first absorbent portion uses material with lower absorbency suitable for urine collection, while the second absorbent portion uses material with higher absorbency for excrement containment. This local differentiation of material properties enables the single absorbent member to effectively handle both types of waste without requiring multiple separate components.
2Ease of manufacture
If existing ostomy pouch replacement devices require preassembly, then manufacturing precision is improved, but ease of operation deteriorates as ostomates must perform complex assembly procedures
Solution Approach 1:
The device is designed to be pre-assembled during manufacturing with the absorbent member already positioned within the pouch body and skin barrier. This preliminary assembly eliminates the need for ostomates to perform complex assembly procedures at home, while still maintaining manufacturing precision. The pre-assembled device can be directly applied to the skin, significantly improving ease of operation.
3Device complexity
If existing devices do not provide customizable fit for individual stoma diameters, then device complexity is reduced, but reliability deteriorates due to potential leakage
Solution Approach 1:
The device incorporates adjustable or flexible components that can adapt to different stoma diameters. The skin barrier and pouch body are designed with flexible materials and adjustable features that allow customization to fit individual stoma sizes while maintaining reliable sealing. This dynamic adaptability ensures leak-free performance across different users without significantly increasing device complexity.

AI summary
An ostomy pouch replacement device allows ostomates with a surgically created stoma to collect, contain and dispose of bodily fluids during hygienic maintenance. The device is customizable to each ostomate's unique stoma diameter and provides a disposable waste receptacle having a hollow absorbent section and a solid absorbent section for sanitary, discreet and odorless disposal of both urine and excrement. The disposable waste receptacle may include a super absorbent polymer powder that becomes a gel in the presence of liquid. The device preferably consists of a disposable waste receptacle that may be positioned over the stoma and includes an absorbent inner material for capturing waste, a cap or plug for scaling the device after use, and a collar stand for pressing an adhesive wafer to the skin and for holding the assembled device in an upright position.
