Catheter Securement via Integrated Adhesive Strips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing intravenous catheters to patients are cumbersome and time-consuming, often requiring both hands of the clinician or a second assistant to apply adhesive strips after catheterization.
Innovation Solution
An intravenous catheter assembly with integrated adhesive strips or straps on a securement platform, featuring a non-adhesive backing for protection during insertion and a foldable configuration to reduce size, allowing for temporary securement without hindering catheter insertion and enabling easy adjustment post-catheterization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive strips are applied after catheterization using separate hands or assistants, then securement is achieved, but procedural time and complexity increase
Solution Approach 1:
The adhesive strip is integrated directly onto the catheter hub, merging the securement function with the catheter assembly itself. This eliminates the need for separate application steps by different hands or assistants, allowing single-handed catheterization and securement while reducing procedural time and complexity
2Reliability
If adhesive strips are applied after catheterization, then securement is achieved, but the process becomes cumbersome and complex
Solution Approach 1:
The adhesive strip is integrated directly onto the catheter hub, merging the securement function with the catheter assembly itself. This simplifies the overall device and process by eliminating separate securement components and steps, reducing procedural complexity while maintaining securement reliability
Solution Approach 2:
The integrated adhesive strip on the catheter hub enables the catheter to be self-securing. The clinician can apply the adhesive strip immediately after insertion using the same hand, making the securement process inherent to the catheter application itself rather than a separate cumbersome procedure
3Ease of operation
If adhesive strips are integrated on the catheter adapter, then one-handed securement is enabled, but adhesive properties must be protected during insertion
Solution Approach 1:
A protective coating is applied to the adhesive strip before catheterization to prevent premature activation. The clinician removes this protective layer immediately before applying the adhesive strip to the skin, ensuring the adhesive properties are protected during insertion and handling while enabling easy one-handed application at the point of use
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
Facilitates efficient and one-handed securement of the catheter assembly to the patient, reducing procedural time and complexity while maintaining the adhesive properties until final securement.
Implementation Method 1
an adhesive strip applied to the underside of the securement platform... so as to form a bond with the skin of a patient

AI summary
An intravenous catheter device is provided which includes an integrated adhesive strip whereby to secure the catheter adapter to the skin of a patient following catheterization. Some aspects of the present invention further comprise an adhesive strap that is coupled to the catheter adapter of a catheter assembly. One end of the adhesive strap is removed from the catheter adapter and wrapped around a body part or surface of the patient, and secured back to the catheter adapter. Thus, the catheter assembly is secured to the patient via the adhesive strap.
