Dry Break Fluid Container Ports for Hazardous Drug Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid containers with ports are unsafe for administering hazardous drugs as they lack mechanisms to prevent the release of hazardous liquids and vapors during connection and disconnection from syringes and patient sets, and are susceptible to contaminant entry during these processes.
Innovation Solution
The introduction of a dry break mechanism in fluid containers that forms a coupling with a second device to prevent the release of hazardous substances and contaminants, featuring a septum and adaptor body with a passage and ledge configuration to ensure secure sealing during connections and disconnections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional ports are used in fluid containers, then ease of operation is improved, but safety against hazardous substance release and contaminant entry deteriorates
Solution Approach 1:
The dry break mechanism acts as an intermediary between the port and external devices. It includes a self-sealing membrane that automatically seals when the port is disconnected, preventing hazardous substance release and contaminant entry while maintaining ease of connection and disconnection operations
2Ease of operation
If ports are designed for easy connection and disconnection, then ease of operation is improved, but prevention of hazardous substance release deteriorates
Solution Approach 1:
The dry break mechanism incorporates a self-sealing membrane that automatically seals the port when disconnected from external devices. This self-service feature prevents hazardous substance release without requiring additional manual sealing actions, maintaining ease of operation while eliminating harmful releases
3Ease of operation
If ports are designed for easy connection and disconnection, then ease of operation is improved, but prevention of contaminant entry deteriorates
Solution Approach 1:
The dry break mechanism serves as an intermediary barrier between the external environment and the fluid container interior. The self-sealing membrane automatically closes when disconnected, preventing contaminants from entering the container while allowing easy connection and disconnection operations
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
The dry break mechanism effectively prevents the release of hazardous aerosols into the environment and entry of contaminants into the container, ensuring safe handling and transfer of hazardous drugs.
Implementation Method 1
the port includes a membrane that fluidly separates the interior volume of the container body from the septum
Implementation Method 2
The dry break mechanism effectively prevents the release of hazardous aerosols into the environment and entry of contaminants into the container

AI summary
A fluid container has a container body defining an interior volume, a port providing access to the interior volume, and a dry break attached to the port for forming a dry break coupling with a second device. The fluid container can be part of a closed fluid transfer system that includes the fluid container and a closed system transfer device. The dry break on the fluid container defines a first passage in fluid communication with the port. A first septum seals the first passage. The closed system transfer device has a housing configured to receive at least a portion of the dry break. A carrier is movable in the housing. The carrier defines a second passage and includes a second septum that seals the second passage. A cannula is at least partially disposed in the second passage.
