Fecal Collection Interface Assembly for Pressure Sore Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fecal collection systems are inadequate for individuals with limited or impaired mobility, as they often require complex installation, pose discomfort, and risk pressure sores due to prolonged contact with the skin.
Innovation Solution
A fecal collection system comprising a user interface assembly with an adhesive sheet, a drainage conduit, and a collection reservoir, designed for easy application and removal, with features like one-way valves and quick-connect couplers to minimize skin contact and facilitate periodic replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the collection system remains continuously coupled to the user's skin, then fecal collection efficiency is improved, but the risk of pressure sores and skin discomfort increases
Solution Approach 1:
The collection system is divided into separable components: the user interface assembly that contacts the skin and the collection reservoir that collects feces. This segmentation allows the skin-contact portion to be removed periodically for skin relief while maintaining collection capability, thus reducing pressure sores while preserving collection efficiency.
Solution Approach 2:
The system enables periodic detachment and reattachment of the user interface assembly from the skin. This periodic action provides skin relief to prevent pressure sores while maintaining overall collection efficiency through systematic reattachment after brief removal periods.
2Measurement precision
If the system requires frequent detachment for monitoring, then diagnostic monitoring is improved, but collection continuity and user comfort deteriorate
Solution Approach 1:
The collection reservoir incorporates visual indicators such as color-coded markings or transparent sections that allow fecal volume and characteristics to be monitored without complete system removal. This enables diagnostic monitoring while maintaining collection continuity and user comfort.
Solution Approach 2:
The drainage conduit acts as an intermediary element that can be independently accessed or replaced without removing the entire system from the user. This allows monitoring and maintenance actions without disrupting overall collection continuity.
3Reliability
If complex installation procedures are used, then collection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The user interface assembly is pre-prepared with adhesive surfaces and alignment features before application. This preliminary preparation ensures reliable attachment while simplifying the actual installation process, as users only need to apply pre-configured components rather than assemble complex structures during installation.
Solution Approach 2:
The system incorporates flexible and adjustable components that can be easily positioned and secured during installation. The dynamic nature of the assembly process allows for simple user-friendly installation while maintaining reliable collection performance through proper positioning and secure attachment.

AI summary
In an example, a fecal collection system includes a user interface assembly, a drainage conduit, and a collection reservoir. The user interface assembly includes a user interface and an applicator. The user interface has a proximal side and a distal side. The proximal side is configured to couple to skin of a user. The applicator is coupled to the distal side of the user interface. The applicator is removable from the user interface while the user interface is coupled to the user. The drainage conduit extends between a proximal end and a distal end. The proximal end is configured to couple to the distal side of the user interface. The drainage conduit defines a lumen configured to guide feces from the proximal end to the distal end. The collection reservoir coupled to the distal end of the drainage conduit.
