Flexible Catheter Securement Straps for Low-Profile Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing catheter securement devices are not adequately soft, pliable, and low-profile while effectively securing catheters to prevent dislodgement and ensuring user-friendly application and removal.
Innovation Solution
A flexible universal catheter securement device with a base and cover system that uses adhesive and mechanical resistance, featuring articulation points aligned with the catheter axis for securement, allowing longitudinal and lateral stabilization through straps or straps with Velcro material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional securement devices are used to prevent catheter dislodgement, then catheter stability is improved, but the device becomes rigid and traumatic to the patient
Solution Approach 1:
The securement device uses a flexible base made of soft, pliable material that conforms to the patient's skin and catheter shape, eliminating the need for rigid structures while maintaining securement effectiveness. The flexible construction prevents skin irritation and patient discomfort.
Solution Approach 2:
The device combines multiple materials with different properties: a flexible adhesive base for comfort and conformity, Velcro® straps for adjustable securement, and a semi-rigid cover for structural support. This composite approach achieves both patient comfort and reliable catheter stabilization.
2Reliability
If traditional securement devices are used to prevent catheter movement, then catheter stability is improved, but the device profile increases and becomes less comfortable
Solution Approach 1:
The flexible base and thin strap construction allow the device to maintain a low, flat profile that conforms to the patient's body contours, eliminating bulky components while providing effective securement through adhesive and mechanical resistance.
3Reliability
If traditional securement devices are used to secure catheters, then catheter stability is improved, but application and removal become difficult
Solution Approach 1:
The device is divided into separable components: an adhesive base that remains on the patient and removable straps that can be easily detached. This segmentation allows for simple application by attaching the base first, then securing the straps, and easy removal by detaching the straps without disturbing the adhesive base.
Solution Approach 2:
The Velcro® strap system allows for self-adjusting securement where the straps can be easily fastened and adjusted by the user or caregiver without requiring complex tools or procedures, facilitating quick application and removal.

AI summary
The present invention pertains to a flexible universal catheter securement device having a longitudinal axis perpendicular to a transverse axis. The securement device preferably secures catheters with a hub. The device has a lower base attached to an upper base having a first integral securement strap and a second integral securement strap. The lower base has an upper side and a lower side, each having an adhesive. When the first strap and second strap are in an open position, the straps extend longitudinally from the upper base at folding lines parallel to the transverse axis. The straps are preferably separated by a circular opening smaller than the outside diameter of the hub. Each strap has an inside edge, where the inside edge comprises a portion of the circular opening and the inside edge is longer than the outside edge of the strap.
