Fluid Collection Barrier With Adhesive Base to Prevent Slippage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid collection devices, such as bed pans and urinary catheters, are uncomfortable, prone to discomfort, and can cause hygiene issues, urinary tract infections, and may slip from the gluteal cleft, rendering them ineffective for individuals with limited mobility or impaired mobility.
Innovation Solution
A fluid collection device with a fluid impermeable barrier and a fluid permeable body, featuring a second outer surface portion with enhanced adhesive strength, tack, or lower surface roughness to secure within the gluteal cleft, and a composition including silicone or TPE with oil, combined with a conduit for vacuum-assisted fluid removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fluid collection devices (bed pans, urinary catheters) are used, then fluid collection function is provided, but user comfort and hygiene deteriorate due to discomfort, pain, and infection risks
Solution Approach 1:
The device is segmented into distinct functional zones: a fluid collection chamber, a base securement area with adhesive properties, and a fluid permeable body with wicking capability. This segmentation allows each zone to optimize its specific function while collectively providing comfortable and hygienic fluid collection
Solution Approach 2:
The fluid permeable body is made of porous or wicking material that allows fluid to pass through from the collection chamber to the external environment. This porous structure enables passive fluid removal without requiring catheters, thereby eliminating infection risks associated with urinary tract catheterization
2Ease of operation
If the device is designed to be lightweight and simple, then ease of use improves, but securement reliability deteriorates causing slippage from the gluteal cleft
Solution Approach 1:
The base of the device features a localized securement area with enhanced adhesive properties, specifically designed to interact with the gluteal cleft anatomy. This localized quality enhancement provides reliable securement without requiring the entire device to be complex or heavy
Solution Approach 2:
The device incorporates composite material properties, combining a flexible fluid collection chamber with a base material that has superior adhesive characteristics. This composite approach allows the device to maintain simplicity and lightness while achieving reliable securement through the specialized base material
3Reliability
If the device uses materials with high adhesive strength, then securement reliability improves, but material complexity and manufacturing difficulty increase
Solution Approach 1:
High adhesive strength is applied locally only to the base securement area that contacts the gluteal cleft, rather than throughout the entire device. This localized application of enhanced material properties achieves reliable securement while keeping the rest of the device simple and easy to manufacture
Solution Approach 2:
The adhesive properties of the base material are optimized by adjusting material parameters such as tackiness and surface roughness. By carefully controlling these material parameters within specific ranges, the device achieves reliable securement using standard manufacturing processes without requiring complex or exotic materials
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 removes fluids, including urine, while minimizing discomfort and preventing slippage, thereby improving hygiene and user comfort.
Implementation Method 1
The fluid permeable body is positioned at least partially within the chamber to extend across at least a portion of the opening and configured to wick fluid away from the opening
Implementation Method 2
a second end region distal to the first end region and including a second outer surface portion having more adhesive strength than the first outer surface portion

AI summary
Example fluid impermeable barriers of fluid collection devices and methods of forming a fluid impermeable barrier of a fluid collection device. The fluid impermeable barrier includes an inner surface at least partially defining a chamber, a first end region defining an aperture extending therethrough and including a first outer surface portion, and a second end region distal to the first end region and including a second outer surface portion having more adhesive strength than the first outer surface portion. The fluid impermeable barrier also defines an opening extending longitudinally along the fluid impermeable barrier and configured to be positioned adjacent to a female urethra.
