Multiport IV Delivery Device with Rotating Outlet and Anti-Reflux Valves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IV infusion devices fail to effectively reduce or eliminate the risk of infection, particle infusion, and air infusion during the administration of multiple time-sensitive medications, particularly in anesthesia delivery, due to the need for frequent port disinfection and multiple connections, which increases the risk of contamination and infection.
Innovation Solution
The development of multi-port, multi-formulation IV delivery devices with anti-reflux valves, filters, and a rotating outlet port that allows for simultaneous delivery of multiple medications without disconnecting syringes, reducing the need for frequent port disinfection and minimizing the risk of contamination through self-priming and minimal dead volume design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple connections and frequent port disinfection are performed to deliver multiple medications, then medication delivery capability is improved, but the risk of infection and contamination increases
Solution Approach 1:
The device divides the medication delivery system into multiple independent inlet ports (at least two), each capable of receiving separate medications simultaneously. This segmentation allows multiple medications to be delivered through a single connected device without requiring repeated connections and disconnections to the IV line, thereby reducing contamination risk while maintaining versatile medication delivery capability
Solution Approach 2:
The device acts as an intermediary component between multiple medication sources and the IV line. By providing multiple inlet ports that converge into a single outlet connected to the IV line, it eliminates the need for frequent disconnections and reconnections, thereby reducing the risk of infection and contamination while enabling simultaneous delivery of multiple medications
2Reliability
If anti-reflux valves and filters are added to reduce infection and particle infusion risk, then patient safety is improved, but device complexity increases
Solution Approach 1:
The device combines multiple safety functions into a single integrated unit: anti-reflux valves are integrated into the inlet ports to prevent backflow, filters are built into the system to trap particles, and the overall structure merges these components into one cohesive device that maintains patient safety while avoiding the need for multiple separate components
Solution Approach 2:
The device performs multiple functions simultaneously within a single structure: it delivers multiple medications through separate inlet ports, prevents backflow through integrated anti-reflux valves, filters particles through built-in filtration, and connects to the IV line through a single outlet. This multi-functionality improves patient safety without proportionally increasing device complexity
3Ease of operation
If a rotating outlet port with gear and pawl mechanism is used to allow rotation without loosening, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The outlet port incorporates a dynamic rotation mechanism with a gear and pawl that allows the port to rotate freely for positioning while maintaining a secure connection to the IV line. The gear-pawl mechanism enables controlled movement without compromising connection integrity, improving ease of operation during medication administration
4Object-affected harmful factors
If minimal dead space design is implemented to reduce contamination risk, then infection risk is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The device design extracts and eliminates unnecessary internal volumes and dead spaces from the medication flow path. By carefully designing the internal geometry to minimize stagnant areas where contamination could occur, the device reduces infection risk while the precision manufacturing ensures that these minimal dead spaces do not compromise medication delivery accuracy
