Syringe Adapter Large Bore High Viscosity Medication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing syringe systems struggle with efficiently withdrawing and administering high-viscosity medications due to difficulty in flow and lack of leverage, leading to prolonged withdrawal times and increased physical effort, which can result in frustration and reduced medication effectiveness.
Innovation Solution
A syringe adapter with a large diameter opening at the distal end and a tapered interior surface, designed for use with pistol-grip or tab-handled syringes, facilitates the withdrawal of high-viscosity medications and provides improved leverage for injection, allowing for easier administration by connecting to the syringe using a Luer-type lock or slip connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional syringe system is used to withdraw high-viscosity medication, then the syringe structure is simple, but the withdrawal time is prolonged and physical effort is increased
Solution Approach 1:
The syringe system is segmented into three functional components: a large-bore adapter for withdrawal, a syringe barrel for containment, and a needle for injection. This segmentation allows each component to be optimized for its specific function, with the adapter providing a large opening for rapid withdrawal of high-viscosity medication while the needle handles the injection task.
Solution Approach 2:
The large-bore adapter serves as an intermediary component between the medication container and the syringe barrel. It facilitates the withdrawal of high-viscosity medication by providing a large opening that reduces resistance, then transfers the medication to the syringe for administration.
2Ease of operation
If a standard syringe is used for high-viscosity medication, then the structure is simple, but leverage for injection is insufficient
Solution Approach 1:
The injection function is separated from the withdrawal function. The adapter-syringe-needle assembly allows the user to apply leverage at the syringe handle while the needle delivers the medication, providing mechanical advantage for injecting high-viscosity substances without complicating the overall system.
3Productivity
If a small opening is used in the syringe tip, then the structure is simple, but flow of high-viscosity medication is restricted
Solution Approach 1:
Different parts of the system have different opening sizes optimized for their specific functions. The adapter has a large opening (0.0625 inches or greater) for rapid withdrawal, while the needle has a smaller opening appropriate for injection. This local differentiation of quality allows high flow rate during withdrawal while maintaining injection capability.
4Loss of time
If a large-bore adapter is used for withdrawal, then withdrawal efficiency is improved, but the system becomes more complex
Solution Approach 1:
The adapter is designed to be universally compatible with standard syringes using Luer connections, allowing it to work with existing syringe barrels and needles. This multi-functionality reduces the need for entirely new equipment while providing the benefits of large-bore withdrawal capability.

AI summary
Apparatus for use with medication in fluid form, which is particularly beneficial for medications having a relatively high viscosity. The disclosed syringe adapter has an opening that is relatively large, as compared to a conventional needle, and thus affixing the disclosed syringe adapter to a syringe improves syringeability of higher-viscosity medications. When the disclosed syringe adapter is affixed to a pistol-grip or tab-handled syringe, the medication withdrawn into the pistol-grip syringe can be more easily administered from the syringe barrel. In some embodiments, the syringe adapter will be replaced with a needle prior to injecting the medication, while in some other embodiments, the needle is affixed to the in-place syringe adapter for the injection. In yet other embodiments, the needle is affixed to a needle holder that, in turn, is affixed to the in-place syringe adapter for the injection.
