Swivel IV Catheter Support Pads for Joint Flexion Patency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing and stabilizing intravenous catheters often cause discomfort and skin irritation due to the use of adhesive tapes or straps, and they fail to maintain patency of the catheter when joints are flexed, leading to occlusion and reduced therapy effectiveness.
Innovation Solution
A medical device with dual pad members and a swivel mechanism that stabilizes the catheter by distributing pressure and allowing joint movement, using layers of low-friction and high-density materials to maintain patency without direct attachment to the catheter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If adhesive tapes or straps are used to secure intravenous catheters, then the catheter is stabilized, but patient discomfort and skin irritation increase
Solution Approach 1:
The patent introduces a securement device with a cover and pad members as an intermediary between the catheter and the patient's skin. The cover swivels upon the catheter while pad members extend outward to distribute pressure, preventing direct contact between adhesive elements and the skin, thus eliminating skin irritation while maintaining catheter stability.
Solution Approach 2:
The patent changes the physical parameters of the securement device by using a swivel mechanism that allows rotational movement and pad members with specific density gradients (higher density near the cover, lower density toward the skin). This enables the device to adapt to joint movements while distributing pressure evenly, maintaining stability without causing discomfort.
2Stability of the object's composition
If traditional securing methods are used, then the catheter is fixed in place, but patency is lost when joints are flexed due to occlusion
Solution Approach 1:
The patent employs a dynamic securement device where the cover can swivel upon the catheter and pad members can compress and deform. This dynamic structure allows the device to accommodate joint flexion and extension movements while maintaining constant pressure distribution around the catheter, preventing occlusion and ensuring continuous patency during patient movement.
Solution Approach 2:
The securement device is segmented into a cover portion that interfaces with the catheter and pad members that interface with the patient's body. This segmentation allows independent movement of each component - the cover swivels with catheter movement while pad members distribute pressure independently, maintaining patency during joint flexion.
3Reliability
If rigid securing devices are used to maintain catheter patency, then joint movement is restricted, but patient comfort and mobility are reduced
Solution Approach 1:
The patent uses flexible pad members made of compressible material that can deform and conform to joint movements. These flexible structures maintain constant contact and pressure distribution around the catheter while allowing full range of motion in the joint, ensuring patency without restricting mobility.
Solution Approach 2:
The securement device incorporates dynamic elements including a swivel mechanism that rotates with joint movement and flexible pad members that compress and expand. This dynamic design maintains catheter stability and patency while fully accommodating natural joint flexion and extension, preserving patient mobility.

AI summary
The intravenous therapy support device has a securement and a cover structured to swivel. Two elongated and resilient pad members extend outwardly from the cover. Each pad member has a low-friction fabric cover layer, a support layer, and a comfort layer. The support layer has a higher density than that of the comfort layer. Pad members are spaced apart and aligned parallel to each other to create a central elongated opening that accommodates the intravenous catheter. The cover swivels to align the central elongated opening with a longitudinal axis of the intravenous catheter. Securement of the device on a patient stabilizes the patency of the intravenous catheter to prevent occlusion.
