Transparent Adhesive Securement Device for Hemodialysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing securement devices in the medical field are opaque, making it difficult for healthcare providers to visualize the insertion site, and are not easily adjustable, which complicates procedures like hemodialysis and can be abrasive to the skin.
Innovation Solution
A transparent securement device assembly with a non-adhesive substrate and strategically applied adhesive, featuring apertures and perforations to allow for easy adjustment and minimal skin irritation, comprising a transparent adhesive layer and a removable layer with specific adhesive sections and perforations for securement and dressing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If opaque securement devices are used, then securement strength is improved, but visualization of the insertion site deteriorates
Solution Approach 1:
The securement device uses a transparent adhesive layer that allows visualization of the insertion site while maintaining adhesive properties only in specific regions. The adhesive layer is transparent in the area covering the insertion site to enable visualization, while having adhesive functionality in other areas to provide securement strength.
2Adaptability or versatility
If tape is removed and reapplied for adjustment, then securement adjustment is achieved, but skin irritation worsens
Solution Approach 1:
The securement device is divided into a removable layer with perforations and an adhesive layer. The removable layer can be separated into sections along the perforations, allowing adjustment of the securement device without completely removing it from the skin. This reduces skin irritation by minimizing repeated removal and reapplication.
3Reliability
If adhesive is applied to entire surfaces, then securement reliability is improved, but ease of adjustment deteriorates
Solution Approach 1:
The adhesive layer has adhesive properties localized to specific regions rather than covering the entire surface. This allows the securement device to maintain reliable adhesion where needed while having non-adhesive regions that facilitate adjustment and removal.
4Illumination intensity
If transparent adhesive layer with selective adhesive application is used, then visualization of insertion site is improved, but manufacturing complexity worsens
Solution Approach 1:
The manufacturing process controls the adhesive properties of the transparent layer by varying adhesive application parameters. The transparent adhesive layer is applied with controlled adhesive content or adhesive pattern, allowing selective adhesion while maintaining transparency. This can be achieved through controlled adhesive dispensing or by using adhesive materials with spatially varying properties.
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
Enables clear visualization of the insertion site, facilitates easy adjustment of the securement device without removing the tape, and minimizes skin irritation during medical procedures like hemodialysis, improving procedural efficiency and patient comfort.
Implementation Method 1
a transparent adhesive layer and a removable layer secured to the bottom surface of the adhesive layer with at least a portion of the adhesive layer extending beyond the removable layer
