Labial Fluid Collection Structure for Secure External Urine Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid collection devices, such as bed pans and urinary catheters, are uncomfortable, prone to hygiene issues, and can cause infections, making them unsuitable for individuals with limited mobility or restricted travel conditions.
Innovation Solution
A fluid collection device with a fluid impermeable barrier and a fluid permeable body having a protruding portion designed to fit between the labia, which includes a conduit for removing fluids, and can be secured using adhesive flaps, straps, or geometric means to maintain position during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bed pans are used for fluid collection, then fluid collection capability is provided, but discomfort and hygiene issues occur
Solution Approach 1:
The device divides the fluid collection function into separate components: an external collection chamber positioned between the labia, a protruding portion that interfaces with the urethra, and a conduit for fluid removal. This segmentation allows each component to be optimized for its specific function while maintaining overall hygiene and comfort
Solution Approach 2:
The protruding portion acts as an intermediary element between the urethra and the collection chamber. It is sized and shaped to fit between the labia and engage with the urethra, serving as a mediator that enables fluid collection without direct contact between the collection chamber and the urethra, thereby improving hygiene
2Reliability
If urinary catheters are used for fluid collection, then fluid collection capability is provided, but discomfort, pain, and infections occur
Solution Approach 1:
The invention extracts the collection chamber from the body interior and positions it externally between the labia. Only the minimal necessary protruding portion interfaces with the urethra, while the main collection function occurs externally. This extraction eliminates the need for deep insertion and reduces infection risk
Solution Approach 2:
Instead of inserting a collection device into the body as with traditional catheters, this invention inverts the approach by positioning the collection chamber externally and having fluid flow outward to the collection point. This reversal eliminates internal foreign body presence and associated complications
3Ease of operation
If a protruding portion is designed to fit between labia for securement, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The protruding portion is designed with specific local qualities - being sized and shaped to fit between the labia - while the rest of the device maintains a simpler structure. This localized specialization provides securement without requiring complex mechanisms throughout the entire device
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 while minimizing discomfort and reducing the risk of infections, providing a hygienic and comfortable solution for individuals with mobility impairments.
Implementation Method 1
a fluid permeable body positioned at least partially within the chamber to extend across at least a portion of the opening and configured to allows fluid to move away from the opening
Implementation Method 2
a vacuum source fluidly connected to the fluid storage container, the vacuum source being configured to provide vacuum force into the chamber via the fluid storage container and the conduit

AI summary
Examples relate to systems, devices, and methods utilizing means for securing a protruding portion of a fluid permeable body disposed between a wearer's labia in position during use. The protruding portion is formed from fluid permeable material that allows urine or other fluids to pass therethrough. The fluid permeable body is disposed at least partially within a fluid impermeable barrier to prevent leakage of the fluid. The fluid is removed through a conduit disposed in a chamber within the fluid impermeable barrier.
