Antimicrobial Catheter Securement Device with Positional Shift Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical catheters pose risks of infection and positional shifts, and current solutions require multiple devices, which are cumbersome and inefficient, and often necessitate costly and risky radiographic imaging for positional verification.
Innovation Solution
A single device with antimicrobial adhesive and a securement system using a film with a hinge mechanism that secures the catheter, providing a guide channel and positional shift indicators to prevent movement and alert healthcare providers without radiographic studies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple devices are used to address catheter associated problems, then comprehensive protection is achieved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple previously separate devices into a single integrated catheter management device. The securement device includes an adhesive film with antimicrobial properties, a securement foundation, a securement cover, and a hinge member, all integrated into one unit that provides securement, antimicrobial protection, and positional verification functions simultaneously.
Solution Approach 2:
The single device performs multiple functions: it secures the catheter to prevent dislodgement, provides antimicrobial protection at the insertion site, and enables positional verification through radiopaque indicators. This multi-functional design eliminates the need for multiple separate devices while comprehensive protection is maintained.
2Measurement precision
If radiographic imaging is used to verify catheter position, then measurement precision is achieved, but patient exposure to radiation and cost increase
Solution Approach 1:
The patent introduces radiopaque indicators as an intermediary that enables positional verification without direct radiographic imaging. These indicators are embedded in the adhesive film and securement components, allowing healthcare providers to assess catheter position through visual inspection of the indicators' position relative to anatomical landmarks, thereby eliminating the need for repeated radiographic studies.
Solution Approach 2:
The patent replaces the mechanical/radiographic verification system with a visual indicator system. Instead of using radiographic imaging to verify catheter position, the device uses radiopaque materials that can be seen through the skin and securement components, allowing positional assessment through simple visual inspection or single imaging rather than repeated radiographic studies.
3Strength
If adhesive is applied to secure the film to the body, then securement strength is improved, but risk of infection increases
Solution Approach 1:
The patent uses a composite adhesive material that combines securing properties with antimicrobial properties. The adhesive film includes an adhesive layer with antimicrobial agents embedded within it, creating a composite material that simultaneously provides strong securement and protection against infection at the catheter insertion site.
Solution Approach 2:
The patent converts the potential harm of adhesive application (infection risk) into a benefit by incorporating antimicrobial properties into the adhesive itself. The adhesive not only secures the device firmly to the skin but also actively prevents infection, turning a previously harmful function into a beneficial one.

Data Source
AI summary
An antimicrobial, securement, and position verification device for medical catheters is disclosed. A film, medical grade adhesive, and antimicrobial substance disposed on the medical grade adhesive operate in conjunction to secure the device to the patient's skin and to prevent infections. The catheter is secured by guide channels in the foundation and securement cover through the use of one or more adhesives impregnated with antimicrobial substances. The device further comprises catheter position alert media and indicators configured to indicate any unintentional positional changes.
