Compressible Urine Collection Casing for Comfortable External Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urinary collection methods, such as urinary catheters and bed pans, are uncomfortable, prone to complications, and pose hygiene issues for individuals with limited mobility or incontinence, particularly affecting elderly females who are bedbound.
Innovation Solution
A fluid collection device with a compressible casing and porous material that can be elastically deformable, positioned in the pubic region to collect and transport urine, utilizing a fluid conduit and suction device for efficient fluid extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If urinary catheters are used to collect urine, then urine collection is achieved, but discomfort and infections occur
Solution Approach 1:
The device divides the urine collection function into separate components: an external compressible casing that collects urine from the pubic region, and a suction device that actively removes urine. This segmentation eliminates the need for internal catheters that cause discomfort and infections while maintaining reliable urine collection.
Solution Approach 2:
The compressible casing acts as an intermediary between the body and the suction device. It collects urine externally and transfers it to the suction device for removal, eliminating direct contact between catheters and the urinary tract, thereby preventing infections and discomfort.
2Reliability
If bed pans are used for toileting, then urine collection is achieved, but spills and hygiene issues occur
Solution Approach 1:
The suction device continuously or periodically removes urine from the compressible casing, preventing accumulation and potential spills. This continuous action maintains hygiene by ensuring urine is promptly transported away, eliminating the spill risks associated with bed pans.
3Ease of operation
If the casing is made compressible for comfort, then ease of operation is improved, but structural strength may be reduced
Solution Approach 1:
The casing is constructed from compressible material that can elastically deform to conform to the pubic region, providing comfort and ease of operation. The flexible shell maintains sufficient structural integrity to contain urine while adapting to body contours, resolving the contradiction between comfort and strength.
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 provides a comfortable and hygienic solution for urine collection, minimizing leakage and discomfort, and allows for reliable retention and transport of urine without absorption, suitable for individuals with limited mobility.
Implementation Method 1
The casing can include or otherwise be formed of a compressible material which is elastically deformable when the fluid collection device is disposed in a pubic region of a female user
Implementation Method 2
The fluid collection device includes a porous material disposed within the internal volume and in fluid communication with the opening

AI summary
A device suitable for collecting and transporting urine away from the body of a person including a casing defining an internal volume and an opening. The casing can include a compressible material which is elastically deformable when the device is disposed in a pubic region of a female user. The device can include a porous material disposed within the internal volume and in fluid communication with the opening. The porous material can wick, draw, or direct fluid, such as urine, away from the pubic region of the female user and into the internal volume. The device can include a fluid conduit disposed within the internal volume and enabling extraction of fluid from the internal volume. The device can include a fluid impermeable housing disposed within the internal volume and adhered or otherwise affixed to the casing.
