Solution Overview
Problem
Current medical devices used in infusion therapy face challenges in preventing pathogenic colonization and biofilm formation, particularly due to incompatibility of certain materials with anti-pathogenic coatings, leading to increased risk of bloodstream infections.
Innovation Solution
The method involves selectively coating non-critical surfaces of medical devices with anti-pathogenic materials, using a combination of chemical and mechanical bonds to ensure compatibility and effectiveness, while avoiding surfaces with critical dimensions that would be adversely affected by the coating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If anti-pathogenic coating is applied to all surfaces of the medical device, then pathogenic colonization is reduced, but critical device dimensions and functionality are adversely affected
Solution Approach 1:
The patent applies anti-pathogenic coating selectively only to non-critical surfaces of the medical device, specifically excluding surfaces with critical dimensions from coating. This localized application approach reduces pathogenic colonization on applicable surfaces while preserving the precise dimensional tolerances and functionality of critical surfaces that would be adversely affected by coating.
2Reliability
If anti-pathogenic coating is applied to critical surfaces, then pathogenic colonization is reduced, but device functionality and dimensional accuracy deteriorate
Solution Approach 1:
The patent identifies and distinguishes between critical and non-critical surfaces, applying the anti-pathogenic coating only to non-critical surfaces. This selective approach maintains the functional performance and operational ease of critical surfaces while still providing infection prevention benefits on the coated non-critical surfaces.
3Ease of operation
If selective coating of non-critical surfaces is implemented, then device functionality is maintained, but pathogenic colonization risk remains on uncoated surfaces
Solution Approach 1:
The patent modifies the approach by changing the parameter of coating coverage from comprehensive to selective, specifically targeting non-critical surfaces. This parameter change optimizes the balance between maintaining device functionality and reducing pathogenic colonization risk, acknowledging that complete coverage is not always feasible or desirable.
