Catheter Securement Retainer for Angle Adjustment and Tube Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing catheter assemblies, such as using adhesives or sutures, are time-consuming, increase infection risk, and fail to prevent catheter rotation or manage extension tubes effectively.
Innovation Solution
A securement device with anchor pads and retainers that include adhesive surfaces for skin attachment, features to inhibit wing movement, and mechanisms to adjust catheter angle and secure extension tubes, along with bracelet-based securement options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesives are used to secure the catheter assembly, then the catheter can be fixed to the patient, but the catheter rotation is not prevented and adjustment of catheter angle is not allowed
Solution Approach 1:
The retainer device incorporates a movable retainer arm that can rotate relative to the base plate, allowing dynamic adjustment of the catheter angle while maintaining secure fixation. This dynamic mechanism enables the catheter to be positioned at different angles without compromising the adhesive bonding or allowing rotation of the catheter assembly itself.
2Reliability
If sutures are used to secure the catheter assembly, then the catheter can be fixed to the patient, but the time to secure the catheter increases and infection risk increases
Solution Approach 1:
The retainer device replaces the mechanical suture system with an adhesive-based fixation system enhanced by a retainer arm. The adhesive provides immediate bonding without the need for needle insertion and thread tying, significantly reducing the time required for catheter securing while maintaining reliable fixation and eliminating the infection risk associated with suture insertion.
3Reliability
If current adhesives are used to secure the catheter assembly, then the catheter can be fixed, but the extension tube is not managed
Solution Approach 1:
The retainer device integrates multiple functions into a single unit: the base plate provides adhesive bonding for catheter fixation, the retainer arm provides mechanical retention and angle adjustment, and the extension tube management feature secures the extension tube alongside the catheter. This multi-functional design simultaneously addresses catheter fixation and extension tube management without requiring separate devices.

AI summary
A securement device for securing a catheter assembly may include one or more anchor pads having an adhesive surface. The securement device may include a retainer positioned on the one or more anchor pads. The retainer may include one or more retaining edges configured to contact a wing of the catheter assembly. The retainer may include a catheter angle adjuster. The securement device may include an extension tube securement element disposed on the one or more anchor pads. Another securement device for securing a catheter assembly may include a bracelet configured to wrap around a wrist of a patient. Another securement device for securing a catheter assembly may include a retainer having a bottom cover and a top cover hingedly coupled to the bottom cover. When the top cover is in the closed position, the retainer may secure the catheter assembly between the top cover and the bottom cover.
