Venipuncture Site Protector with Segmented Catheter Stabilizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing intravenous catheters are inadequate, leading to complications such as phlebitis, infiltration, extravasations, dislodgement, disconnection, and infection due to unwanted movement, necessitating unscheduled catheter restarts and exposing healthcare workers to risks.
Innovation Solution
A venipuncture site protector with a securement and cover that includes a slotted partitioned body member with internal walls to securely capture the catheter and tubing, preventing movement through frictional engagement and adhesive securing, thereby reducing complications and unscheduled restarts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If surgical tape is used to secure the intravenous catheter to the skin, then the catheter can be fixed in place, but micro-movement of the catheter occurs which leads to complications such as phlebitis, infiltration, extravasations, dislodgement, disconnection, and infection
Solution Approach 1:
The device divides the catheter securement function into separate components: a securement member with adhesive for skin attachment, and a catheter stabilizing member that provides structural support and frictional engagement. This segmentation allows each component to optimize its specific function without the compromises of a single integrated solution.
Solution Approach 2:
The catheter stabilizing member acts as an intermediary between the skin-attached securement and the catheter itself. It provides a stable interface that prevents micro-movement while allowing the catheter to remain securely positioned in the vein without direct adhesive contact.
2Ease of operation
If a uniform angle of insertion is used for all IV sites, then the insertion process is simplified, but improper insertion angle occurs at sites with varying tissue amounts leading to complications such as phlebitis
Solution Approach 1:
The device allows for dynamic adjustment of insertion angle by providing a flexible catheter path and adjustable securement positioning. The catheter can be inserted at the optimal angle for each specific anatomical site, and the device adapts to maintain proper positioning rather than enforcing a rigid uniform angle.
3Reliability
If the catheter is left unsecured to avoid movement, then movement-related complications are reduced, but dislodgement and disconnection occur more frequently
Solution Approach 1:
The catheter stabilizing member functions as a flexible protective structure that conforms to the patient's anatomy while providing securement. This flexible shell approach allows the catheter to be held firmly in place without rigid constraints that could cause dislodgement, preventing both excessive movement and complete disconnection.

AI summary
A venipuncture site protector that includes a securement and a cover mounted to said securement. The cover includes a proximal end having a front wall with a tube receiving slot. The cover also includes a distal end having an arch that forms an opening that lies on a vertical plane that is substantially perpendicular to the securement.
