Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricants used in syringes, such as silicone and hydrocarbon oils, are difficult to detect and analyze, leading to challenges in testing, property determination, and quality control, particularly in syringes and medical device stoppers, due to issues like low layer thickness, rapid detection, and migration.
Innovation Solution
A colorized oil comprising silicone or hydrocarbon oils combined with fluorescent acrylic compositions or ultraviolet dyes that fluoresce at specific wavelengths, allowing for improved detection and analysis through imaging systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lubricants (silicone or hydrocarbon oils) are used in syringes, then lubrication function is provided, but detection and analysis become difficult
Solution Approach 1:
The patent applies colorization compounds to the lubricant oil to enable visual detection. The oil is formulated with dyes or fluorescent materials that provide distinct coloration, allowing easy observation of the lubricant layer thickness, distribution, and behavior during syringe operation. This resolves the detection difficulty while preserving the lubrication function.
Solution Approach 2:
The patent introduces colorization compounds as intermediary substances that do not interfere with the lubrication mechanism but enable detection. These compounds act as mediators between the lubricant and detection systems (visual inspection, imaging systems), allowing quality control without compromising the oil's lubricating properties.
2Productivity
If thin layers of lubricant are applied to syringe surfaces, then lubrication efficiency is improved, but detection becomes more difficult
Solution Approach 1:
The colorization compounds provide high-contrast visual indication that enhances the visibility of thin lubricant layers. Even when applied as thin films for optimal lubrication efficiency, the colored or fluorescent markers ensure the layers remain detectable through visual inspection or imaging systems, resolving the contradiction between thin-layer efficiency and detectability.
3Difficulty of detecting and measuring
If fluorescent acrylic compositions or ultraviolet dyes are added to oils, then visibility and detection are enhanced, but formulation complexity increases
Solution Approach 1:
The patent modifies the chemical composition parameters of the lubricant by incorporating fluorescent acrylic compositions or ultraviolet dyes at specific concentrations. These parameter changes enable enhanced visibility and detection capabilities while maintaining compatibility with the base oil and syringe materials, achieving improved detectability without excessive formulation complexity.
