Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods of securing catheters to patients using tape are cumbersome, prone to causing infections, and lead to motion-related complications like phlebitis and catheter migration, while also requiring frequent changes that can excoriate the skin and leave adhesive residue.
Innovation Solution
A securement device with a base and foldable securement arms that cradle the catheter, featuring an adhesive surface protected by a release layer, and a transparent cover to securely attach to the patient's skin without tape, allowing for easy monitoring of the catheterization site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive tape is used to secure the catheter to the patient, then the catheter can be held in position, but the tape can retain dirt or contaminant particles leading to infection
Solution Approach 1:
The securement device is divided into distinct functional segments: a base member with adhesive portion for skin attachment, a cradle portion for catheter support, and securement arms for stabilization. This segmentation allows each component to perform its specific function while minimizing contaminant retention areas, as the structured design reduces crevices where dirt can accumulate compared to traditional tape applications.
Solution Approach 2:
The transparent cover member acts as an intermediary barrier between the external environment and the catheterization site. It protects the site from contaminants while allowing visual observation, thereby reducing infection risk without compromising catheter stability. The cover creates a controlled interface that prevents direct contact between contaminants and the securement components.
2Reliability
If adhesive tape is used to secure the catheter, then the catheter can be held in position, but catheter motion is not limited leading to motion related complications
Solution Approach 1:
The securement device segments the stabilization function into multiple components: the base member provides anchor points, the cradle portion supports the catheter body, and the securement arms actively limit motion. This multi-component approach provides comprehensive motion restriction in multiple directions, preventing phlebitis and catheter migration more effectively than single-layer tape.
Solution Approach 2:
Different portions of the device provide different types of constraint: the adhesive base provides fixed attachment to skin, the cradle provides gentle support and positioning, and the securement arms provide active motion limitation. This localized functional differentiation ensures appropriate constraint at each interaction point with the catheter, minimizing motion-related complications.
3Adaptability or versatility
If adhesive tape is frequently removed and reapplied, then the catheter can be repositioned or replaced, but the skin can be excoriated and adhesive residue can build up
Solution Approach 1:
The securement device is designed as a disposable component that can be easily removed and replaced. The entire device including base, cradle, and securement arms can be discarded after a single use, eliminating the cumulative skin damage and adhesive residue problems associated with repeated tape applications. The low cost of the disposable device makes frequent replacement practical without harming patient skin.
Solution Approach 2:
The device enables easy discarding of the securement components after use, with the catheter itself being recovered and reused. The disposable securement device is discarded to prevent skin excoriation and adhesive residue buildup, while maintaining the ability to reposition or replace the catheter as clinically needed.
4Reliability
If a securement device with multiple components is used, then catheter stability is improved, but device complexity increases
Solution Approach 1:
Multiple functional components (adhesive base, cradle, securement arms, and transparent cover) are merged into a single integrated device structure. The components are pre-assembled during manufacturing as one unit, simplifying the application process for clinicians while maintaining all the stabilization benefits of the multi-component design. This merging reduces the complexity of assembly and ensures proper positioning of all elements.
Solution Approach 2:
The securement device performs multiple functions within a single integrated structure: the base provides adhesive attachment, the cradle supports the catheter, the securement arms limit motion, and the transparent cover protects the site while allowing observation. This multi-functionality reduces the need for separate components and simplifies the overall system while achieving comprehensive catheter stabilization.

AI summary
A securement device for securing a catheter to a patient is provided. The securement device includes a base including a support member and at least one securement arm extending away from the support member. The support member defines a cradle portion, the cradle portion of the support member being configured to receive at least, a portion, of a catheter. The at least one securement arm being movable over the cradle portion to a position to secure a catheter within the cradle portion. The securement device further includes a cover member configured to be received over the base and dimensioned to secure the base to a patient.
