Catheter Securement Device Nose Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing catheter securement devices fail to effectively prevent kinking and undesired movement of catheters at the skin insertion site, leading to potential complications and discomfort for patients.
Innovation Solution
A securement device with a retainer system featuring a body, feet, and a nose that stabilizes the catheter hub and strain relief, incorporating adhesive anchor pads for attachment to the skin, and a channel to receive the catheter components, along with features to prevent rotation and kinking, such as pockets for nubs and a lock tab, ensuring secure yet removable retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing catheter securement devices are used, then the catheter can be retained externally, but kinking and undesired movement at the skin insertion site cannot be effectively prevented
Solution Approach 1:
The securement device is divided into distinct functional segments: a body portion for receiving the catheter hub, feet for stabilization, a nose for directional control, and adhesive anchor pads for secure attachment. Each segment addresses specific aspects of catheter stability, collectively preventing kinking and undesired movement while maintaining reliability.
2Reliability
If adhesive anchor pads are used to attach the securement device to the skin, then secure retention is achieved, but the device complexity increases
Solution Approach 1:
The patent combines multiple securement mechanisms into a single integrated device: the body portion with its channel and nose structure is merged with feet that have adhesive anchor pads. This unified structure achieves strong securement while avoiding the complexity of multiple separate components, as the adhesive pads are incorporated directly into the feet of the retainer body.
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 device effectively reduces kinking and undesired movement of catheters, maintaining a stable position and minimizing infection risk through antimicrobial dressings, thus enhancing patient comfort and securement.
Implementation Method 1
Adhesive anchor pads, in use, adhesively attach to the skin surface, to form the securement device

AI summary
A securement device configured to secure an external portion of a medical device to the skin surface of a patient after an internal portion of the device has been placed in the patient is disclosed. The securement device includes a retainer that is employed to securely retain the external portion of the medical device in place. The retainer is attached to a base, such as an adhesive pad that adhesively attaches to the skin surface. In one embodiment, therefore, a retainer comprises a body defining a channel configured to receive therein a portion of the medical device, and at least one foot extending from the body that is configured to stabilize the retainer with respect to a skin surface. The retainer body further includes a nose that is configured to deflect a portion of the external portion of the medical device toward the skin insertion site.
