Catheter Stabilization System with Segmented Anchor Pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for stabilizing medical catheters and tubing on patients using tape are prone to contamination, leading to potential infections and require frequent changes, which can disrupt the stabilization and expose the insertion site to dirt and foreign objects.
Innovation Solution
A stabilization system comprising an anchor pad with a retainer and dressing that secures medical articles, such as catheter extension sets, to the patient's skin, preventing transverse movement while maintaining fluid flow and allowing for easy disconnection without removing the anchor pad, thus minimizing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If tape is used to secure the catheter to the patient, then the catheter is stabilized and movement is restricted, but the insertion site becomes exposed to contaminants and dirt, leading to potential infections
Solution Approach 1:
The device divides the stabilization function into separate components: an anchor pad with adhesive for securing the catheter, and a removable dressing for protecting the insertion site. This segmentation allows each component to perform its specific function optimally without compromising the other.
Solution Approach 2:
The adhesive anchor pad acts as an intermediary between the catheter and the patient's skin, providing secure stabilization while the removable dressing serves as an intermediary protective layer that shields the insertion site from contaminants, preventing direct exposure to harmful factors.
2Stability of the object's composition
If tape is used to stabilize the catheter, then movement is restricted, but frequent tape changes are required which disrupt stabilization and expose the insertion site
Solution Approach 1:
The adhesive anchor pad is designed as a disposable component that remains in place for the duration of catheter use, eliminating the need for repeated tape changes. The removable dressing can be changed without disturbing the anchor pad, reducing the frequency of interventions.
Solution Approach 2:
The adhesive anchor pad is applied in advance to secure the catheter, establishing long-lasting stabilization before the catheter use period begins. This preliminary action eliminates the need for repeated stabilization adjustments during the treatment period.
3Object-affected harmful factors
If tape is applied over the insertion site to protect it, then contamination is reduced, but the catheter stabilization is compromised and movement is not effectively restricted
Solution Approach 1:
The device separates the protection function (removable dressing) from the stabilization function (adhesive anchor pad with retainer). The anchor pad with its retainer structure provides effective catheter restraint, while the dressing independently provides contamination protection without interfering with stabilization.
Solution Approach 2:
The anchor pad combines multiple functions: adhesive attachment to skin, retainer structure for mechanical stabilization of the catheter, and support for the removable dressing. This merging of functions ensures both effective stabilization and protection are achieved simultaneously.
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 system effectively stabilizes medical articles on the patient, reduces contamination risks, and allows for easy maintenance without disrupting the catheter's position, thereby enhancing patient safety and reducing infection risks.
Implementation Method 1
At least a portion of a surface of the anchor pad is covered by an adhesive for attachment to a patient's skin

AI summary
A medical article, such as a connector fitting or extension set, is stabilized on a patient with a retainer and a dressing integrally attached to an anchor pad supporting the retainer. The connector fitting or extension set may be integrally formed with the retainer. The connector fitting or extension set may comprise a spin nut configured to secure to a catheter hub having a catheter connected thereto. One or more of the anchor pad, dressing, and catheter may comprise an antibacterial or antimicrobial agent.
