24-Hour Urine Container With Vacuum Vial Bottom Draw-Off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional urine collection containers face difficulties in efficiently drawing off residual urine from the bottom, leading to impractical pouring operations that risk contamination and spilling.
Innovation Solution
A container design featuring a cup body with a vacuum vial system that allows direct drawing off of residual urine from the bottom without pouring, using a tube and fluidic coupling means to create pressure difference for efficient urine transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional pouring method is used to draw off residual urine, then the container structure remains simple, but the operation becomes impractical and risks contamination
Solution Approach 1:
The patent implements a nested structure where a cup body is inserted into the container, and a vacuum vial is inserted into the cup body. The tube extends from the cup body bottom to reach the container bottom, allowing residual urine to be drawn off through the nested components without requiring the container itself to be complex.
Solution Approach 2:
The patent introduces intermediary components (cup body, vacuum vial, tube) that mediate between the container and the urine sampling process. These intermediaries enable efficient drawing off of residual urine while keeping the main container structure relatively simple.
2Reliability
If pouring operation is used to transfer residual urine, then no additional drawing off mechanism is needed, but spilling and contamination risk increases
Solution Approach 1:
The patent uses a vacuum vial that creates a pressure difference to draw off urine through the tube. This pneumatic mechanism eliminates the need for manual pouring operations, preventing spilling and contamination while maintaining controlled and reliable urine transfer.
3Productivity
If a pump system is used to draw off urine as in US2006/0277670, then residual urine can be efficiently removed, but the device complexity and production cost increase
Solution Approach 1:
The patent employs a self-service mechanism where the vacuum vial automatically creates the necessary pressure difference to draw off urine without requiring an external pump system. The tube is passively positioned to reach the container bottom, and the system self-regulates through the vacuum effect, eliminating complex pumping infrastructure.
Solution Approach 2:
The patent extracts the essential function of urine removal from complex pump systems and implements it through a simplified vacuum-based mechanism. By taking out only the necessary drawing off capability and implementing it through the vacuum vial and tube assembly, the system achieves efficient residual urine removal without the complexity of full pump systems.

AI summary
The present invention relates to a container for the collection of urine over a period of 24 hours, the inner volume of which is defined by a bottom wall (11), a perimetral wall (12) and a top wall (13). The container comprises at least a first access mouth (21) made on the aforesaid top wall (13) or perimetral wall (12). The invention is characterised by the fact of comprising means for drawing off the urine collected in the container, which are firmly associated to, said first access mouth (21).
