Syringe Adapter for High-Viscosity Medication Withdrawal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing syringes struggle with efficiently withdrawing and administering high-viscosity medications due to difficulty in syringeability, leading to increased time and effort, potential leakage, and equipment breakdowns during injection.
Innovation Solution
A syringe adapter with a large diameter opening at the distal end and a Luer-type connection, designed for use with pistol-grip or tab-handled syringes, facilitates the withdrawal of high-viscosity medications from containers and allows for easy injection by replacing the adapter with a needle after withdrawal, improving leverage and reducing syringeability issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a standard syringe is used to withdraw high-viscosity medication, then the syringe structure is simple, but the withdrawal efficiency is low and time-consuming
Solution Approach 1:
The device is divided into two functional components: a syringe adapter for efficient withdrawal of high-viscosity medication and a needle for injection. This segmentation allows each component to be optimized for its specific function, with the adapter featuring a large opening for high-speed withdrawal and the needle providing precise injection capability.
Solution Approach 2:
The syringe adapter acts as an intermediary device between the medication container and the syringe. It features a large opening that facilitates efficient withdrawal of high-viscosity medications by reducing resistance during the withdrawal process, thereby significantly decreasing the time required for medication transfer.
2Strength
If a standard syringe is used for injection, then the structure is simple, but user leverage is insufficient leading to equipment failure
Solution Approach 1:
The syringe adapter is designed with a pistol-grip configuration that provides dynamic leverage advantages during the injection process. The ergonomic handle and angled structure allow users to apply force more effectively, reducing the likelihood of equipment failure when injecting high-viscosity medications that require significant injection force.
3Ease of operation
If a small opening is used in the syringe, then the structure is simple, but syringeability of high-viscosity medication is poor
Solution Approach 1:
The syringe adapter features a significantly enlarged opening diameter compared to standard syringes. This parameter change directly addresses the syringeability problem by reducing flow resistance and allowing high-viscosity medications to be drawn into the syringe more easily and quickly, despite the increased structural complexity of the adapter component.

AI summary
Improved 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. Some embodiments feature a lateral extension that prevents inserting the syringe adapter too far into a medicine bottle, and some embodiments feature a component that assists in firmly grasping. 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.
