Sealed Urine Collection Device with Shielding Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional urine collection methods are inefficient, prone to spills, and result in environmental pollution, with urine samples often collected in excess, causing discomfort and lowering working efficiency in laboratory settings, and the process is not sanitary due to staining of containers and equipment.
Innovation Solution
A disposable sealed body fluid retention device comprising a fluid storage tube, a fluid-taking piece with a guiding and air exhaust passage, a shielding body to prevent spills, and a plug part for sealing, allowing for safe and sanitary collection and transfer of urine without staining the outer container walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional paper cups are used for urine collection, then subjects can easily collect urine samples, but the samples are prone to spills and environmental pollution
Solution Approach 1:
The patent introduces a protective cover as an intermediary component that wraps around the paper cup. This cover acts as a barrier between the urine sample and the external environment, preventing spills and contamination while allowing the subject to easily collect urine in the paper cup underneath. The cover is designed to fit over the cup opening and secure the sample during handling and transport to the laboratory.
2Quantity of substance
If urine samples are collected in excess volume, then complete analysis can be performed, but working environment comfortability deteriorates
Solution Approach 1:
The protective cover serves as a sealed intermediary that contains the urine sample within the paper cup. By covering the cup opening, it prevents urine vapor and odors from escaping into the laboratory environment, thus maintaining working comfortability while allowing adequate sample volume to be collected for complete analysis.
Solution Approach 2:
The protective cover creates a sealed, isolated environment around the urine sample. This sealed space acts as an inert barrier that prevents interaction between the urine vapor and the laboratory air, effectively containing odors and maintaining a comfortable working atmosphere while preserving the sample for analysis.
3Productivity
If urine is transferred to test tubes, then samples can be analyzed, but the outer wall of test tubes gets stained requiring re-transfer
Solution Approach 1:
The protective cover acts as an intermediary transfer mechanism that enables direct, clean transfer of urine samples from the paper cup to the test tube. The cover can be designed with an integrated spout or opening that aligns with the test tube, allowing urine to flow directly into the tube without contacting the outer walls, thus maintaining container cleanliness and eliminating the need for re-transfer.
4Quantity of substance
If multiple urine samples are disposed side by side in the laboratory, then all samples can be processed, but large space is occupied
Solution Approach 1:
The protective cover is designed to fit snugly over the paper cup, creating a compact nested structure. This nested design allows multiple covered samples to be stacked or arranged more efficiently in the laboratory space, reducing the area occupied by each sample while maintaining the protective function. The covers can also be designed to interlock or stack vertically, maximizing space utilization.
