Ostomy Collecting Bag Insert for In-Place Peristomal Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ostomy appliances face issues with adhesive failure due to inadequate cleaning of the peristomal skin surface, which is exacerbated by aggressive stomal output and foul smells, making the appliance change process cumbersome and stressful, especially in public settings.
Innovation Solution
A collecting bag for ostomy appliances with an insert member featuring a penetrable zone and expandable design, allowing for in-situ cleaning of the peristomal skin surface using the old appliance, while maintaining it in place, and accommodating sudden gas bursts without detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the peristomal skin surface is thoroughly cleaned before applying a new ostomy appliance, then adhesive integrity is improved, but the cleaning process becomes cumbersome and time-consuming
Solution Approach 1:
The collecting bag is designed with an integrated cleaning system that includes a cleaning liquid reservoir and dispensing mechanism. The cleaning liquid is prepared and delivered directly to the peristomal skin surface through the bag structure, eliminating the need for separate cleaning steps. This preliminary preparation of cleaning resources within the appliance structure resolves the contradiction by making thorough cleaning quick and integrated into the appliance change process
Solution Approach 2:
The patent combines the collecting bag, cleaning liquid reservoir, and dispensing mechanism into a single integrated structure. The cleaning system is merged with the appliance itself, allowing cleaning to occur directly through the bag without requiring external water sources or separate cleaning materials. This merging resolves the contradiction by consolidating multiple functions into one streamlined system that maintains adhesive integrity while minimizing time loss
2Reliability
If access to water source and tissues is required for cleaning the peristomal skin surface, then cleaning effectiveness is improved, but convenience deteriorates especially in public settings
Solution Approach 1:
The collecting bag contains an integrated cleaning liquid reservoir and dispensing system that provides all cleaning resources self-contained within the appliance structure. The system delivers cleaning liquid directly to the peristomal skin surface through built-in dispensing mechanisms, eliminating the need for external water sources, tissues, or toilet paper. This self-service capability resolves the contradiction by making effective cleaning completely independent of external facilities, thereby maximizing convenience in public settings
Solution Approach 2:
The collecting bag is designed to perform multiple functions: waste collection, gas management, and integrated skin cleaning. The cleaning subsystem includes a reservoir, dispensing mechanism, and integrated application method that works independently of external facilities. This multi-functionality resolves the contradiction by making the appliance universally applicable in any setting, whether private or public, without compromising cleaning effectiveness or requiring additional resources
3Object-generated harmful factors
If the collecting bag is designed to expand to accommodate sudden gas bursts, then gas containment is improved, but the risk of adhesive detachment increases
Solution Approach 1:
The collecting bag is constructed with a multi-layer structure that includes an expandable body portion and a separate, reinforced adhesive interface. The bag body can expand independently to accommodate gas bursts, while the adhesive interface remains structurally separate and reinforced to maintain attachment. This segmentation resolves the contradiction by allowing the bag to expand for gas containment while keeping the adhesive bond intact and secure
Solution Approach 2:
The collecting bag incorporates pre-designed expansion zones and flexible structural elements that are prepared in advance to accommodate sudden gas bursts. These cushioning features are built into the bag structure before use, allowing the bag to expand smoothly without creating sudden stress spikes that could detach the adhesive. This beforehand cushioning resolves the contradiction by preparing the structure to handle gas bursts while maintaining adhesive integrity throughout the expansion process

AI summary
A collecting bag (20) for an ostomy appliance including an insert member which includes two layers (36, 38) of polymeric film located between a proximal wall (25a) and a distal wall (25b) of the collecting bag at least at a top half of the bag. One of the layers of polymeric film of the insert member comprises a penetrable or weakened zone (52) which is adapted to be penetrated by a conduit or similar by a means for delivering a cleaning liquid. The collecting bag makes it possible for a user to clean the peristomal skin surface or area with a cleaning liquid with the collecting bag still being attached to the user's body.
