Pneumatic Fluid Collection Device with Segmented Gas Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid collection devices, such as bed pans and urinary catheters, face issues like discomfort, spills, hygiene concerns, and the risk of urinary tract infections, and are not suitable for individuals with limited mobility or those requiring fluid collection for monitoring purposes.
Innovation Solution
A fluid collection device with a fluid impermeable barrier and a channel extending between an inlet and an outlet, where the inlet is connected to a gas source and the outlet is connected to a fluid storage container, allowing gas flow to suction fluids into the channel and direct them towards the storage container, preventing contamination and damage to the gas source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If urinary catheters are used to collect fluids, then fluid collection is achieved, but discomfort and risk of urinary tract infections increase
Solution Approach 1:
The device divides the fluid collection system into separate functional components: an external collection chamber positioned away from the urethra, a separate gas flow channel, and a distinct fluid transfer mechanism. This segmentation eliminates the need for a catheter to remain in the urethra, reducing discomfort and infection risk while maintaining reliable fluid collection capability
Solution Approach 2:
The device introduces gas flow as an intermediary mechanism to transfer fluid from the collection chamber to the storage container. This intermediary approach allows fluid removal without requiring a catheter to stay inserted in the urethra, thereby reducing discomfort and infection risk while maintaining effective fluid collection
2Reliability
If bed pans are used for fluid collection, then fluid collection is achieved, but spills and hygiene issues occur
Solution Approach 1:
The device uses pneumatic principles by introducing gas flow through a channel to actively draw fluid from the collection chamber and transport it to the storage container. This controlled gas-driven fluid transfer eliminates spills and maintains hygiene by providing a closed, controlled fluid transfer path rather than manual pouring or gravity-dependent drainage
Solution Approach 2:
Gas flow serves as an intermediary medium that transfers fluid from the collection chamber to the storage container in a controlled manner. This intermediary mechanism prevents direct contact and potential spills, improving hygiene while maintaining reliable fluid collection
3Productivity
If a vacuum source is used to suction fluids, then fluid collection efficiency is improved, but the gas source becomes contaminated and damaged
Solution Approach 1:
The device introduces a fluid transfer channel as an intermediary component between the collection chamber and the gas source. This channel allows gas to flow through and create suction for efficient fluid collection, while the channel structure prevents direct contact between the gas source and collected fluid, eliminating contamination and damage risks
Solution Approach 2:
The system is segmented into distinct zones: a collection chamber for fluid accumulation, a transfer channel for gas flow and fluid removal, and a separate storage container. This segmentation allows the gas source to drive fluid collection efficiently through the channel while being physically isolated from the fluid, preventing contamination and damage
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 solution effectively collects fluids without causing discomfort or contamination, is suitable for environments without a vacuum source, and reduces the risk of urinary tract infections, providing a hygienic and efficient method for fluid collection.
Implementation Method 1
flowing gas from an inlet to an outlet of a channel of the fluid collection device that is effective to suction the fluids into the channel from the chamber

AI summary
In an embodiment, a fluid collection device includes a fluid impermeable barrier that at least partially defines a chamber. The fluid impermeable barrier also defines an opening extending therethrough that is configured to be positioned adjacent to a female urethra or have a male urethra positioned therethrough. The fluid collection device also includes a channel extending between an inlet and outlet thereof. The inlet is configured to be in fluid communication with a gas source and the outlet is configured to be in fluid communication with a fluid storage container. The outlet is positioned downstream from the inlet. The channel also defines at least one aperture or passageway therein that allows an interior of the channel to be in fluid communication with the rest of the chamber.
