Ostomy Collar Drape and Barrier for Enhanced Seal Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy appliances often struggle to maintain a sufficient seal around the stoma, leading to leakage and irritation of the peristomal skin, particularly due to anatomical variations such as sunken stomas or skin folds.
Innovation Solution
The use of a collar drape and a barrier, which can be used separately or in combination with an ostomy appliance, to enhance the seal around the stoma. The collar drape is an adhesive assembly with an elastic, stretchable material that generates compressive forces to improve the seal, while the barrier provides a secure adhesive surface for the ostomy appliance to adhere to, reducing direct contact with the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base is made to adhere directly to the skin, then the seal should be secure, but the skin becomes irritated or inflamed due to contact with ostomy output
Solution Approach 1:
The patent introduces a collar drape as an intermediary component between the base and the skin. The collar drape includes an adhesive layer that secures to the skin and a fluid-impermeable layer that prevents contact between ostomy output and the skin, while the base seals to the collar drape rather than directly to the skin. This mediator protects the skin from harmful factors while maintaining seal security.
2Reliability
If the base is made larger to improve sealing, then the seal should be better, but the device complexity and skin exposure increase
Solution Approach 1:
The patent divides the sealing system into separate functional components: the base provides the primary seal, the collar drape provides skin protection and additional sealing, and the barrier provides reinforcement. This segmentation allows each component to be optimized for its specific function without requiring a single oversized base, reducing overall device complexity while maintaining effective sealing.
3Reliability
If the collar drape is made more elastic to accommodate anatomical variations, then the seal should be better, but the material strength may be reduced
Solution Approach 1:
The collar drape is constructed as a composite material system with an elastic stretchable flexible material providing adaptability to anatomical variations, reinforced by a non-stretchable reinforcing layer that maintains structural strength. The adhesive layer provides secure attachment. This composite structure allows the collar drape to simultaneously achieve high elasticity for seal adaptability and sufficient strength for durable use.
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 combination of the collar drape and barrier significantly reduces the potential for leakage and irritation by creating a more secure seal around the stoma, improving comfort and skin health for ostomy wearers.
Implementation Method 1
The adhesive assembly comprises an elastic stretchable flexible material which generates compressive forces when stretched

AI summary
A collar drape and a barrier are disclosed which can be used with an ostomy appliance to form an enhanced seal with a wearer's stoma. The collar drape comprises a collar drape body defining a collar drape opening sized to be equal to or slightly smaller than an outer diameter of the neck of the ostomy appliance. The barrier comprises a barrier base defining a barrier opening spaced from a perimeter of said barrier. The barrier base is formed from a material to which said ostomy appliance flange can be removable adhered. The barrier base defines a perimeter greater than a perimeter of a flange of the ostomy appliance.
