Venipuncture Base Plate Assembly with Variable Angle Adapter
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 undesired catheter movement and improper insertion angles, necessitating unscheduled restarts and posing risks to patients and healthcare workers.
Innovation Solution
A venipuncture base plate assembly with a retention clip and patient interface platform that allows for secure attachment of catheters at variable angles, using an adapter with a retention clip and a base pad with adhesive for stable fixation, reducing catheter movement and enabling adjustable insertion angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surgical tape is used to secure the catheter to the skin, then the catheter can be attached to the skin surface, but micro-movement of the catheter occurs leading to complications such as phlebitis, infiltration, extravasations, dislodgement, disconnection, and infection
Solution Approach 1:
The device divides the catheter securing function into multiple components: a base plate for skin attachment, a retention clip for catheter clamping, and a positioning mechanism for angle control. Each component performs a specific function, collectively providing stable catheter fixation without the micro-movement problems of tape alone.
Solution Approach 2:
The base plate acts as an intermediary between the skin and the catheter retention system. It provides a stable foundation that distributes attachment forces, preventing the micro-movement that occurs when tape directly contacts the catheter and skin without a rigid backing structure.
2Adaptability or versatility
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 or flesh surrounding the vein leading to complications such as phlebitis
Solution Approach 1:
The device incorporates a dynamic positioning mechanism that allows the catheter to be secured at multiple variable angles relative to the skin surface. This enables adaptation to different anatomical sites and tissue depths while maintaining proper vein alignment, resolving the contradiction between uniformity and adaptability.
Solution Approach 2:
The device allows changing the insertion angle parameter based on the specific anatomical site and patient anatomy. By providing adjustable angle options, the system optimizes the insertion angle for each situation rather than using a fixed uniform angle, preventing complications like phlebitis.
3Ease of manufacture
If surgical tape is used to secure the catheter, then attachment to the skin is achieved, but tape is not designed to secure a catheter resulting in undesired movement and necessitating unscheduled catheter restarts
Solution Approach 1:
The base plate serves multiple functions: it provides skin attachment surface, structural support for the retention clip, and angle positioning capability. This multi-functional design replaces the inadequate single-function tape with a comprehensive securing system that addresses all aspects of catheter stabilization.
Solution Approach 2:
The device appears to be a disposable single-use system that provides reliable catheter securement for the duration of IV therapy. By designing a complete securement system as a disposable unit, it eliminates the need for repeated catheter restarts that would occur with inadequate tape securing, improving overall reliability despite the added complexity.
