Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antimicrobial materials used in healthcare, such as those containing silver or chlorhexidine, face issues with leaching and environmental toxicity, and there is a need for effective antimicrobial compounds that can maintain microbial control on surfaces like luer locks without entering the bloodstream.
Innovation Solution
A covalently bound antimicrobial compound, such as chlorhexidine, is integrated into a polymeric material to form an antiseptic polymeric material that can be contacted with luer locks, providing antimicrobial properties without leaching into the bloodstream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silver or chlorhexidine is used as antimicrobial agent in fabrics, then antimicrobial efficacy is improved, but the agent leaches out during washing and over time causing toxicity and environmental harm
Solution Approach 1:
The patent changes the chemical state of the antimicrobial agent from free/loose form to covalently bound form. Specifically, chlorhexidine is covalently bonded to the polymer fabric through chemical reactions that create stable bonds, fundamentally changing how the agent interacts with the fabric structure and prevents leaching while maintaining antimicrobial activity.
Solution Approach 2:
The patent creates a composite material system where chlorhexidine molecules are chemically integrated with polymer fibers. This composite structure combines the antimicrobial properties of chlorhexidine with the structural integrity of the fabric, resulting in a material where the active agent becomes an intrinsic part of the fabric matrix rather than a surface coating.
2Reliability
If antimicrobial compound is applied to luer lock surface, then microbial control is improved, but the compound may enter intravenous line and be exposed to patient bloodstream
Solution Approach 1:
The patent changes the physical state and binding characteristics of the antimicrobial compound on the luer lock surface. By covalently bonding chlorhexidine to the polymer material of the luer lock, the compound transitions from a free, mobile state to a fixed, bound state that prevents migration into the intravenous line while maintaining surface antimicrobial activity.
Solution Approach 2:
The patent uses the polymer material of the luer lock as an intermediary carrier. The covalently bound chlorhexidine on the polymer surface acts as a controlled interface that provides antimicrobial protection without allowing direct transfer of the compound to the intravenous line or patient bloodstream.
3Reliability
If existing antimicrobial materials are used, then some microbial protection is achieved, but they are ineffective at eliminating airborne microorganisms
Solution Approach 1:
The patent changes the chemical structure and binding characteristics of the antimicrobial agent to enhance its effectiveness against a broader range of microorganisms including airborne pathogens. The covalent bonding of chlorhexidine to the polymer matrix creates a sustained-release effect and maintains consistent antimicrobial activity on the surface, which is particularly effective against airborne microorganisms that contact the surface.

AI summary
An antiseptic polymeric material, wherein an antimicrobial compound is covalently bonded to the material, and the material is used for contacting with a luer lock. The antiseptic polymeric material may help disinfect or prevent any further microbial contamination to the luer lock, wherein the use of a covalently bound antimicrobial compound may also reduce any risk of having the antimicrobial compound entering the intravenous line and being exposed to the patient bloodstream. Preferably, the antiseptic polymeric material may be used in the healthcare industry for disinfection, the suppression of, reduction in and/or maintenance of the microbial load on a surface of the luer lock.
