Fluid Container Unit With Single Nozzle For Dual Drug Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of preparing and handling two bottles containing different drug solutions for sterilizing treatments is cumbersome and prone to errors, and requires two injection ports, which complicates the equipment design and reduces compactness.
Innovation Solution
A fluid container unit is designed with a parallel arrangement of two containers, integrated using a container coupling and a supply/discharge port opening mechanism, allowing simultaneous discharge through a single nozzle, enhancing fixing workability and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two bottles are unitized in parallel arrangement, then the two types of bottles can be fixed to the injection site without being mistaken and the two types of drug solutions can be simultaneously injected, but two injection ports must be provided on the injection side which becomes an inhibiting factor in making the fluid usage equipment compact
Solution Approach 1:
The patent merges two separate injection ports into a single injection port by providing a mixing chamber where both drug solutions are mixed before injection. The container coupling integrates the first and second containers with a common nozzle member, allowing both fluids to be supplied through one injection port rather than requiring two separate ports.
2Reliability
If two bottles are unitized in parallel arrangement, then the two types of bottles can be fixed to the injection site without being mistaken, but the two injection ports must be accurately aligned and fixed to the receiving ports which is a drawback in enhancing the fixing workability
Solution Approach 1:
The container coupling merges the discharge ports of both containers into a single common discharge port that connects to one injection port. This eliminates the need for accurate alignment of multiple injection ports while maintaining the reliability of preventing wrong bottle usage, as the parallel arrangement of containers is preserved but the injection interface is simplified.
3Adaptability or versatility
If two bottles are simply unitized in parallel arrangement, then the two types of bottles can be fixed to the injection site, but two injection ports must be provided which complicates the equipment design
Solution Approach 1:
The patent introduces a mixing chamber as an intermediary component between the two containers and the single injection port. The mixing chamber receives both drug solutions from the first and second containers, mixes them together, and then supplies the mixed solution through a single nozzle member to the injection site. This intermediary structure enables simultaneous injection capability while simplifying the injection site design.

AI summary
A fluid container unit including: a container coupling for coupling a supply/discharge port of a first container with a supply/discharge port of a second container; a single nozzle member having a nozzle tube; a connection cap having a first end for holding a base portion of the nozzle member and a second end for covering one side of the container coupling by fitting around an outer periphery thereof; an intermediate adaptor having a pair of pusher elements facing the first and the second supply/discharge ports, respectively; and a supply/discharge port opening mechanism for moving the intermediate adaptor toward the container coupling and opening the supply/discharge ports by the pusher elements. The pusher elements are movably held in a direction along a longitudinal axis of the nozzle tube in the connection cap.
