One-Time Priming IV Extension Set with Flow Reversal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional IV extension sets require time-consuming and inefficient priming processes, where each tubing branch must be individually connected to a syringe to remove air bubbles, leading to potential contamination and incorrect medication dosages.
Innovation Solution
A one-time priming IV extension set design that allows simultaneous priming of all tubing branches by connecting a syringe to one branch, using a slide clamp to reverse priming fluid flow through the system, and incorporating air venting membranes to prevent bubble accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each tubing branch is individually connected to a syringe for priming, then air bubbles can be removed from each branch, but the priming process becomes time-consuming and inefficient
Solution Approach 1:
The patent combines multiple tubing branches into a common fluid pathway that allows a single syringe to prime all branches simultaneously. The multi-lumen connector and Y-connector design enable one priming fluid source to flow through multiple tubings at once, eliminating the need to connect and prime each branch separately.
Solution Approach 2:
The patent creates a universal priming system where a single syringe connection point can service multiple tubing branches. The common fluid pathway and multi-lumen connector allow one priming operation to perform the function of what would otherwise require multiple separate priming operations for each branch.
2Productivity
If multiple syringes are used to prime each tubing branch simultaneously, then priming time is reduced, but device complexity and contamination risk increase
Solution Approach 1:
The patent merges multiple tubing branches into a common fluid pathway with a single syringe connection point. This consolidation allows one syringe to prime all branches simultaneously through the multi-lumen connector and Y-connector design, reducing device complexity while maintaining high priming speed.
Solution Approach 2:
The patent segments the fluid pathway into distinct lumens within a single connector assembly. The multi-lumen connector contains separate channels for different tubing branches, allowing one syringe to independently prime each branch through internal segmentation rather than requiring multiple external syringe connections.
3Adaptability or versatility
If traditional IV extension set design is used, then multiple medications can be delivered independently, but priming requires individual connection to each branch
Solution Approach 1:
The patent creates a universal connector design that maintains the ability to deliver multiple medications independently through separate tubing branches while providing a single universal priming access point. The multi-lumen connector and Y-connector enable one syringe to prime all branches without compromising the independent medication delivery capability.
Solution Approach 2:
The patent combines multiple medication delivery pathways into a single priming interface. The common fluid pathway with multi-lumen connector merges the priming function for all branches into one operation, while the separate tubing branches remain intact for independent medication administration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design significantly reduces priming time, prevents air bubble entrapment, and minimizes contamination risks, ensuring accurate medication delivery and patient safety.
Implementation Method 1
The slide clamp may be configured to restrict fluid flow between the proximal and distal ends of the outlet tubing in a closed configuration to cause priming fluid flowing into the outlet tubing via the multi-tubing connector to reverse direction and flow into the at least one secondary inlet tubing via the primary multi-tubing connector.

AI summary
A multi-tubing intravenous (IV) extension set may include an outlet tubing fluidly coupled to a primary multi-tubing connector at one end and fluidly coupled to a vascular device at an opposite end, and a primary inlet tubing having a proximal end with an adapter for connection to a syringe containing a priming or a medicinal fluid, and a distal end coupled to the primary multi-tubing connector. The IV extension set may further include at least one secondary inlet tubing with a proximal end having an adapter for receiving a medicinal fluid and a distal end selectively fluidly coupled to the primary multi-tubing connector. A slide clamp may be positioned on the outlet tubing to restrict flow between the proximal and distal ends of the outlet tubing and cause priming fluid flowing into the outlet tubing via the multi-tubing connector to reverse direction into the at least one secondary inlet tubing.
