Drug Injector Adapter for Needle Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drug delivery systems using needles can cause injection phobia and generate medical waste, while needleless systems lack the ability to incorporate needles as needed.
Innovation Solution
A drug injector adapter that is attachable to and detachable from a needleless drug injector, featuring a fixing portion, coupling portion, and sealing portions to securely connect a needle, allowing for the delivery of drugs through a tightly sealed flow passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a needleless drug injector is used, then patient comfort is improved and medical waste is reduced, but the ability to deliver drugs via needle injection is lost
Solution Approach 1:
The adapter enables dynamic reconfiguration of the drug delivery system, allowing users to switch between needleless and needle-based injection modes as needed. The adapter can be attached to convert a needleless injector into a needle-compatible device, and detached to restore the needleless configuration, providing flexible adaptation to different clinical requirements
Solution Approach 2:
The adapter serves as an intermediary component that bridges the needleless injector and needle assembly. It includes a coupling portion with a coupling groove that receives the needle, and a flow passage that connects the injector's flow passage to the needle's flow passage, enabling fluid communication while maintaining the ability to operate in both needleless and needle modes
2Productivity
If a needle-based drug delivery system is used, then accurate and efficient drug administration is achieved, but patient comfort deteriorates and medical waste increases
Solution Approach 1:
The system allows dynamic switching between needle and needleless modes based on clinical needs. The adapter can be attached when needle-based injection is required for accurate and efficient drug administration, and removed when needleless injection is sufficient, enabling flexible optimization of both treatment efficacy and patient comfort
Solution Approach 2:
The adapter design allows for selective use and disposal of needles while recovering and reusing the expensive injector device. The adapter can be detached and the needle removed, allowing the injector to be reused for subsequent needleless injections, thereby reducing medical waste and cost
3Adaptability or versatility
If an adapter is added to enable needle coupling, then versatility is improved, but device complexity increases
Solution Approach 1:
The adapter merges multiple functions into a single integrated component: it includes a fixing portion that attaches to the injector, a coupling portion that receives the needle, sealing portions that ensure fluid-tight connections, and a flow passage that enables drug flow. This consolidation achieves versatility without excessive complexity
Solution Approach 2:
The adapter is designed as a universal interface that can be attached to needleless injectors to enable needle-based injection. The coupling groove and sealing mechanisms are designed to work with standard needle configurations, providing multi-functional capability while maintaining relatively simple structure
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
Enables the conversion of a needleless drug injector to a needle-based system, allowing for flexible drug delivery options and reducing waste by allowing various needles to be coupled, addressing the limitations of both needle and needleless systems.
Implementation Method 1
a first sealing portion configured to allow the fixing portion to come into close contact with the drug injector
Implementation Method 2
the first sealing portion may be formed of an elastic material
Implementation Method 3
the adapter housing may comprise a second sealing portion that is in close contact with the delivery flow passage of the drug injector adapter and the flow passage of the needle to connect them in a tightly sealed state
