Modular Syringe Manifold for Fluid Injector Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical fluid injection systems restrict user mobility and simplicity, requiring users to remain close to the injector assembly while filling syringes, which limits workflow and user experience.
Innovation Solution
A syringe manifold system with a modular design featuring upper, middle, and lower body members, including fluid conducting elements, check valves, and floating disc valves, allowing for fluid communication between syringes and fluid containers, enabling easy filling and connection to fluid delivery devices, and allowing users to move freely during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional injector design with controller located on the face of the injector assembly is used, then the user can monitor and control the injection, but the user must remain within arms-length of the injector assembly which limits mobility
Solution Approach 1:
The controller is separated from the injector assembly and placed on a handheld device, allowing the user to control and monitor the injection remotely while maintaining mobility throughout the treatment room
Solution Approach 2:
A wireless communication system acts as an intermediary between the injector assembly and the handheld controller, enabling remote operation without requiring the user to be physically close to the injector
2Productivity
If fluid containers are inverted and hung on an adjacent IV stand for filling syringes, then the filling process can be performed, but the user must remain close to the injector assembly which restricts workflow
Solution Approach 1:
The fluid delivery system is divided into separate modular components including the injector assembly, handheld controller, and fluid containers, allowing the user to move freely between these components during the procedure
Solution Approach 2:
The system allows the user to independently access and fill syringes from fluid containers while maintaining the ability to monitor and control the injection remotely through the handheld device, eliminating the need to remain stationed at the injector assembly
3Measurement precision
If a fixed volume and rate of injection is programmed into the electronic control system, then precise delivery of contrast and saline is achieved, but the system requires complex programming and monitoring at the injector assembly
Solution Approach 1:
The handheld controller serves as an intermediary interface between the user and the electronic control system, providing a simplified method to program and adjust injection parameters while maintaining precise control through wireless communication with the injector assembly
Solution Approach 2:
The control interface is replicated on the handheld device, allowing the user to access and modify injection parameters remotely without needing to interact with the physical controls on the injector assembly

Function Achieved in This Case
Enhances user experience by enabling free movement during fluid injection procedures, simplifies the filling process, and improves workflow efficiency by allowing multi-patient use and quick refilling of syringes from multi-dose containers.
Implementation Method 1
The manifold assembly includes a floating disc valve configured to permit fluid flow from the at least one syringe to the patient line and prevent backflow
Implementation Method 2
The manifold assembly includes a check valve configured to permit fluid flow from the at least one fluid container to the at least one syringe
