Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current catheter shields are inadequate in providing effective water resistance and hygiene, often causing skin irritation, failing to prevent moisture-induced infections, and are not comfortable for long-term use, leading to increased risks of nosocomial bloodstream infections.
Innovation Solution
A water-resistant catheter shield with a fluid-impermeable sleeve, multiple adhesive layers for secure attachment, and a moisture indicator to prevent water and bacterial contact, featuring a retention structure to keep the catheter in place and impregnated anti-infective layers to mitigate bacterial and fungal growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If current catheter shields are used, then the catheter entry site is covered, but water and contaminants can still contact the catheter, leading to skin irritation and infection risk
Solution Approach 1:
The shield is divided into multiple functional layers: a fluid-impermeable sleeve for water resistance, multiple adhesive layers for secure attachment, and impregnated anti-infective layers for microbial protection. Each layer performs a specific protective function, collectively providing comprehensive coverage against water and contaminants.
Solution Approach 2:
The shield combines multiple materials with different properties: a fluid-impermeable material for water resistance, adhesive materials for attachment, and anti-infective impregnated materials for microbial protection. This composite structure achieves protection against multiple harmful factors simultaneously.
2Object-affected harmful factors
If traditional catheter shields are used, then the catheter is covered, but they fail to prevent moisture-induced infections and cause skin irritation
Solution Approach 1:
The shield includes impregnated anti-infective layers that convert the potential harm of moisture contact into a beneficial antimicrobial effect. The anti-infective agents are released when moisture is present, actively preventing infection rather than merely blocking moisture.
Solution Approach 2:
The shield changes the chemical parameters of the protective layers by impregnating them with anti-infective agents. This transforms the physical barrier into an active chemical defense system that prevents microbial growth and reduces skin irritation risks.
3Object-affected harmful factors
If a fluid-impermeable sleeve with multiple adhesive layers is used, then water resistance is improved, but device complexity increases
Solution Approach 1:
Multiple functional layers (fluid-impermeable sleeve, adhesive layers, anti-infective layers) are merged into a single integrated shield structure. This combines water resistance, attachment security, and microbial protection into one device, reducing the need for multiple separate components.
Solution Approach 2:
The shield is designed as a multi-functional device that simultaneously provides water resistance, secure attachment through multiple adhesive layers, and microbial protection through impregnated anti-infective layers. Each layer serves multiple purposes, reducing overall device complexity.
