Vortex Mixing Fluid-Directing Member for Automatic Injector Premixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic injectors that store therapeutic agents in solid form require manual premixing and shaking, which increases administration time, making them unsuitable for rapid delivery in emergency situations.
Innovation Solution
The integration of a fluid-directing member within the injector that creates a vortex, enhancing the mixing of the liquid and dry components, allowing for immediate and effective dissolution of the therapeutic agent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the therapeutic agent is stored in solid form to improve stability and shelf-life, then the therapeutic agent stability is improved, but manual premixing and shaking are required which increases administration time
Solution Approach 1:
The device performs preliminary action by automatically mixing the solid therapeutic agent with liquid immediately before injection through a mechanical agitation mechanism, eliminating the need for manual premixing and shaking by the user while maintaining the stability benefits of solid storage
Solution Approach 2:
The device performs self-service by incorporating an automatic mixing mechanism that agitates and mixes the solid therapeutic agent with liquid component without requiring external manual intervention, thereby reducing administration time while preserving formulation stability
2Productivity
If manual shaking is required to expedite dissolution, then the mixing speed is improved, but the device complexity and user operation difficulty increase
Solution Approach 1:
The device performs self-service by incorporating an automatic mixing mechanism that agitates and mixes the solid therapeutic agent with liquid component without requiring external manual intervention, thereby reducing administration time while preserving formulation stability
Solution Approach 2:
The device replaces the manual mechanical shaking action with an automated mechanical agitation system that performs the mixing function automatically, improving mixing speed while eliminating the need for user manual operation
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
This design enables faster and more complete dissolution of the dry therapeutic agent, ensuring quicker and more effective delivery of the therapeutic agent, even in emergency situations.
Implementation Method 1
By introducing a 'fluid-directing member' that causes the liquid component to form a vortex, mixing of the liquid component with the dry component is improved

AI summary
An automatic injector separately stores liquid and dry components in respective compartments. When the injector is activated, a fluid-directing member between the liquid and dry compartments causes the liquid component to form a vortex as the liquid flows into the dry compartment. This allows the two components to combine more thoroughly and quickly to form a liquid solution that is delivered to an injection site.
