Ostomy Pouch Replacement Device with Dual Absorbent Chambers
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 waste receptacle, featuring an absorbent member with varying levels of absorbency and a superabsorbent polymer powder, along with an optional alignment sleeve, cap, and collar stand, allowing for easy positioning and secure containment of waste without preassembly, ensuring sanitary and discreet disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single absorbent material is used in the receptacle, then the device structure is simple, but it cannot effectively collect and contain both urine and excrement
Solution Approach 1:
The receptacle is divided into two separate chambers: a first chamber containing a first absorbent material optimized for urine absorption, and a second chamber containing a second absorbent material optimized for excrement absorption. This segmentation allows each chamber to be tailored for specific waste types, effectively collecting and containing both urine and excrement while maintaining reasonable structural complexity.
Solution Approach 2:
Different absorbent materials are placed in different locations within the receptacle based on the specific absorption requirements for different waste types. The first absorbent material in the first chamber has properties optimized for liquid urine absorption, while the second absorbent material in the second chamber has properties optimized for solid excrement absorption, creating local quality variations that enhance overall functionality.
2Productivity
If preassembly of the ostomy appliance is required, then the replacement process is faster, but the device cannot be customizable to individual stoma diameters
Solution Approach 1:
The device incorporates an adjustable alignment sleeve that can be customized to fit different stoma diameters. The sleeve includes multiple positioning options or adjustable features that allow the user to adapt the device to their specific stoma size before attaching the ostomy appliance, thereby maintaining both customization capability and replacement efficiency.
Solution Approach 2:
The receptacle design serves multiple functions: it acts as both the waste collection container and the alignment guide for the stoma. By integrating the alignment sleeve and absorbent chambers into a single universal component, the device eliminates the need for separate preassembly steps while still allowing customization to individual stoma diameters.
3Ease of operation
If the absorbent material is applied directly to the stoma, then the device is simple to use, but waste matter can leak onto the surrounding skin
Solution Approach 1:
The absorbent member is nested within the receptacle structure, which itself is positioned over the stoma. The receptacle acts as a containing structure that holds the absorbent material in place, preventing waste matter from leaking onto the surrounding skin while maintaining ease of application. The alignment sleeve further nests within the receptacle to ensure proper positioning.
Solution Approach 2:
The receptacle is positioned over the stoma before the ostomy appliance is fully attached, creating a preliminary barrier that prevents waste matter from contacting the surrounding skin during the replacement process. This prior cushioning ensures that even if leakage occurs during application, the waste is contained within the receptacle rather than spreading to the skin.
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 device effectively collects and contains both urine and excrement, providing ostomates with ample time for skin preparation and secure attachment, reducing leakage and infection risks, while allowing for customizable and sanitary disposal.

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 sealing 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.
