Solution Overview

Problem

Current catheter securement devices fail to provide effective and comfortable securement for extended use in patients, as they often dislodge and require complex application and removal processes, lacking atraumatic and user-friendly features.

Innovation Solution

A flexible universal catheter securement device with a base and cover attached at a longitudinal articulation point, featuring adhesive foam padding and optional hook and loop material, which allows for securement by mechanical and adhesive forces, preventing dislodgement and facilitating easy application and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a securement device is made soft and pliable with a low profile, then patient comfort and safety are improved, but the device may fail to provide effective catheter securement and prevent dislodgement

Engineering Contradiction:

Improvepatient comfort and traumaVSAvoidcatheter securement effectiveness

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The securement device combines multiple materials with different properties: a flexible base material for comfort and low profile, adhesive foam padding for securement, and hook and loop material for mechanical attachment. This composite approach allows the device to simultaneously provide patient comfort and effective catheter securement.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The device is divided into distinct functional components: a base portion for adherence to skin, a cover portion for securing the catheter, adhesive foam padding for additional attachment, and hook and loop material for mechanical fastening. Each segment performs a specific function, allowing the overall device to meet multiple requirements simultaneously.

Inventive Principle:

Principle #1Segmentation

2Reliability

If a securement device provides strong mechanical securement to prevent dislodgement, then catheter stability is improved, but the device becomes less soft and pliable, affecting patient comfort

Engineering Contradiction:

Improvecatheter securement effectivenessVSAvoidpatient comfort and trauma

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Different portions of the device have different mechanical properties optimized for their specific functions. The base and cover use flexible materials for comfort, while the adhesive foam and hook and loop materials provide localized strong attachment where needed. This spatial differentiation of material properties allows simultaneous achievement of comfort and securement.

Inventive Principle:

Principle #3Local quality

3Reliability

If a securement device uses complex application and removal processes, then securement effectiveness may be improved, but user-friendliness and ease of application are reduced

Engineering Contradiction:

Improvecatheter securement effectivenessVSAvoidease of application and removal

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The hook and loop material enables the cover to attach and detach through simple mechanical interlocking without requiring complex procedures. The adhesive foam padding provides self-adhering securement that simplifies application. These features allow healthcare providers to quickly apply and remove the device while maintaining effective catheter securement.

Inventive Principle:

Principle #25Self-service

AI summary

The present invention pertains to a flexible universal catheter securement device for use with, e.g. Foley catheters and other catheters. The flexible universal catheter securement device preferably comprises a cover attached to a base at a longitudinal articulation point. The cover has a top cover surface and a bottom cover surface and the bottom cover surface has an adhesive foam padding. The base has a top base surface and a bottom base surface and the top base surface has an adhesive foam padding. The articulation point is foldable such that the cover can be placed on the base. The base and the cover preferably have a centerline and the articulation point is offset there from. The base further comprises a catheter placement axis and the longitudinal articulation point is located parallel to the catheter placement axis. The cover preferably has less surface area than the base.
