Integrated Medicine Mixing Interface for Leakage Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double hard interfaces with medicine mixing nozzles require a hose for connection, leading to increased leakage risks due to welding, material limitations at low temperatures, and complex installation processes.
Innovation Solution
An integrated medicine mixing interface with a medicine mixing nozzle and double hard interfaces, featuring a cross-shaped needle, annular rubber cushions, and a diaphragm for sealing, eliminates the need for a hose and easy-to-break handle, ensuring a simple structure and low cost while preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hose is used to connect the medicine mixing nozzle and medicine mixing interface, then the structure allows flexibility, but the number of welding portions increases leading to higher leakage probability
Solution Approach 1:
The patent removes the hose from the system entirely, extracting the problematic component that caused multiple welding portions and leakage risks. The medicine mixing nozzle is directly integrated with the medicine mixing interface, eliminating the intermediate hose connection and all associated welding joints.
Solution Approach 2:
The medicine mixing nozzle and medicine mixing interface are merged into a single integrated component. This consolidation eliminates the need for separate hose connections and multiple welding operations, reducing the system to fewer parts with fewer potential failure points.
2Ease of manufacture
If a hose is used for connection, then installation is possible, but the hose may break at welding portions at low temperatures due to material limitations
Solution Approach 1:
The hose is completely removed from the system, eliminating the material limitations associated with hose materials at low temperatures. By extracting this vulnerable component, the patent avoids the problem of hose brittleness and breakage in cold environments.
Solution Approach 2:
The integrated medicine mixing interface uses a composite structure combining rigid components (medicine mixing nozzle, interface body) with flexible sealing elements (rubber cushions). This composite approach provides both structural integrity and flexibility without relying on hose materials that fail at low temperatures.
3Ease of operation
If an easy-to-break handle is installed within the hose, then medicine mixing can be controlled, but the installation process becomes more complex and time-consuming
Solution Approach 1:
The easy-to-break handle is removed from the system. Instead of controlling medicine mixing through a breakable handle in a hose, the patent uses a diaphragm that is punctured by the medicine feeding needle to initiate flow, eliminating the need for the handle component entirely.
Solution Approach 2:
The diaphragm is pre-installed in a sealed position before use. The medicine feeding needle automatically punctures the diaphragm when inserted, initiating the medicine mixing process without requiring manual breaking of a handle or complex activation mechanisms.
4Ease of manufacture
If multiple welding portions are used for hose installation, then connection is achieved, but the probability of leakage at welding portions increases
Solution Approach 1:
The hose is extracted from the system, eliminating all welding portions associated with hose installation. The direct integration of the medicine mixing nozzle with the medicine mixing interface requires no intermediate welding operations.
Solution Approach 2:
The medicine mixing nozzle and medicine mixing interface are merged into one integrated component, eliminating the need for separate welding operations to join hose connections. This reduces the total number of welding portions to zero in the medicine mixing pathway.

AI summary
An integrated medicine mixing interface comprising a medicine mixing mouth (1), hard double interfaces (2) and a medicine feed needle (3). The hard double interfaces (2) comprise a base (21), a medicine mixing interface (22) and an infusion interface (23). The medicine mixing mouth (1) and the medicine mixing interface (22) are integrated. When using the integrated medicine mixing interface, it is only necessary to weld the base (21) to the bag body of a soft infusion bag (11) and integrate the medicine mixing mouth (1) with the medicine mixing interface on the hard double interfaces (2) without adopting a hose connection and an easily folding handle, which not only reduces hose installation location, but also avoids welding leakage brought about by hose welding defects. Moreover, the structure is simple and the costs are low.
