Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Medical catheters are prone to positional shifts leading to infections, and current methods for securing and monitoring their position involve multiple devices, which are cumbersome and require radiographic imaging, exposing patients to radiation and increasing costs.

Innovation Solution

A single device with an adhesive film, base, hinge, and cover forms a secure housing for the catheter, incorporating a positional shift indicator to alert healthcare providers of any shifts without radiographic studies, providing antimicrobial protection and securement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate devices are used to secure and monitor catheters, then catheter security and monitoring functions are provided, but device complexity and ease of operation deteriorate due to the need to manage multiple devices

Engineering Contradiction:

Improvecatheter security and monitoring functionsVSAvoidnumber of devices

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate devices (securement device and monitoring device) into a single integrated catheter securement and monitoring device. The housing contains both the securement mechanism with adhesive film and the monitoring indicator system, eliminating the need for multiple separate devices while providing both catheter security and positional shift detection functions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single integrated device performs multiple functions: it secures the catheter to the patient's body using adhesive film, provides antimicrobial protection through the cover, and monitors catheter position using the indicator visible through the window. This multi-functional design replaces multiple specialized devices with one universal solution.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If radiographic imaging is used to assess catheter positional changes, then positional accuracy is improved, but patient radiation exposure and cost increase

Engineering Contradiction:

Improvecatheter position assessment accuracyVSAvoidradiation exposure

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical/radiographic imaging system with a simple visual indicator system. The catheter position is monitored through a mechanical indicator mechanism that moves in response to catheter displacement, which can be observed directly through a window in the housing, eliminating the need for radiographic imaging.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses a simple, inexpensive visual indicator mechanism instead of expensive radiographic imaging. The indicator is a passive mechanical element that provides continuous monitoring without requiring expensive equipment or exposing patients to radiation, making it a cost-effective alternative.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Object-affected harmful factors

If the cover is designed to completely enclose the catheter, then antimicrobial protection is improved, but ease of catheter insertion and operation worsens

Engineering Contradiction:

Improveinfection protectionVSAvoidcatheter insertion ease

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent designs the cover and housing to be assembled around the catheter before final securement. The catheter is first inserted through the housing, then the cover is placed over it to provide antimicrobial protection. This preliminary assembly allows easy catheter insertion while ensuring complete enclosure for infection protection.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device is divided into separate components (housing, cover, adhesive film) that can be assembled in a logical sequence. The catheter passes through the housing first, then the cover is attached to provide enclosure. This segmented design facilitates easy catheter insertion while achieving complete antimicrobial protection.

Inventive Principle:

Principle #1Segmentation

AI summary

A device for securing and monitoring movement of a catheter includes a film having an adhesive disposed on a body-facing surface for securing the film to a body. The device also includes a base mounted on the film, the base comprising a first portion of a guide channel for receiving the catheter. A cover is coupled to the base via a hinge, the cover comprising a second portion of the guide channel, the cover further comprising a rounded portion extending from a distal end of the cover, wherein in the closed configuration, the catheter is completely enclosed by the rounded portion and the first and second portions of the guide channel. The device also includes a positional shift indicator fixedly attached to the catheter and configured to indicate positional shifts by the catheter within the guide channel.
