Catheter Fixation Kit with Velcro Patches and Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for fixing ECMO catheter tubes, such as adhesive plasters and straps, cause skin damage and fail to provide adequate security, leading to a high risk of catheter dislocation, which is critical and potentially fatal.
Innovation Solution
A set comprising two adhesive patches with Velcro functional areas, a first fixing element forming a loop around the catheter lumens, and a adjustable fixing strap with integrated Velcro elements for secure, skin-friendly fixation without additional headbands, ensuring the catheter tube is securely positioned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ordinary adhesive plasters and fixation tapes are used to fix ECMO catheter tubes, then the fixation method is simple and easy to apply, but the fixation security is inadequate and skin damage occurs
Solution Approach 1:
The fixation system is divided into multiple functional components: adhesive plasters for skin attachment, Velcro fasteners for adjustable securing, and fixation elements for catheter containment. This segmentation allows each component to perform its specific function optimally while working together to provide both ease of application and high fixation security.
Solution Approach 2:
The fixation system combines multiple materials with different properties: adhesive materials for skin bonding, Velcro materials for adjustable fastening, and flexible yet secure fixation elements. This composite approach enables the system to be both easy to apply and highly reliable in maintaining catheter position.
2Reliability
If additional headbands are used to prevent fixation slipping, then the fixation security is improved, but patient comfort deteriorates due to pressure on the crown area
Solution Approach 1:
The harmful headband component that causes pressure on the crown area is completely removed from the fixation system. Instead, the invention uses adhesive plasters positioned on suitable skin areas and a fixation strap that can be adjusted to provide secure fixation without requiring pressure on sensitive areas of the head.
Solution Approach 2:
The fixation strap acts as an intermediary element that distributes the securing force across a larger area and to more suitable locations on the head, avoiding direct pressure on the crown area while still providing the necessary fixation security to prevent slipping.
3Reliability
If fixation materials are applied tightly to ensure security, then the fixation reliability is improved, but skin damage occurs due to excessive pressure
Solution Approach 1:
The fixation system applies pressure locally at specific points through adhesive plasters and fixation elements, rather than distributing tight pressure across large areas of skin. This allows secure fixation to be achieved through targeted local attachment points while leaving the surrounding skin areas free from excessive pressure and damage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure, comfortable, and effective fixation of double-lumen catheter tubes, minimizing the risk of dislocation while maintaining patient safety and comfort, eliminating the need for additional fixation elements like headbands.
Implementation Method 1
The first side has an adhesive, by means of which the patch can be fixed to a patient's skin
Implementation Method 2
The second side of the first patch is equipped with a Velcro functional area
