Needle-Free Syringe Tip for Container Membrane Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing syringes cause needle-stick injuries and require additional components for drawing up medicines from containers, leading to increased material consumption and environmental impact.
Innovation Solution
A syringe system with a modified tip designed to penetrate containers without needles, incorporating a barrel, plunger, and integrated locking mechanisms, allowing direct access to substances without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a blunt needle is used to draw up medicine from a container, then the injection can be made, but needle-stick injuries occur
Solution Approach 1:
The invention removes the needle component entirely from the syringe system. The syringe tip is modified to have a beveled end that can directly penetrate the flexible membrane of medicine containers without requiring a separate needle, thereby eliminating needle-stick injuries while maintaining injection capability.
Solution Approach 2:
The syringe tip is designed to perform multiple functions: it can penetrate flexible membranes of various container types (vials, IV bags), draw up medicines, and deliver injections. This multi-functional design replaces the need for separate needles while maintaining all necessary injection capabilities.
2Adaptability or versatility
If additional components (needles, adapters) are used to draw up medicines from containers, then the syringe can access various container types, but material consumption and costs increase
Solution Approach 1:
The syringe tip incorporates a beveled end design that can directly penetrate the flexible membranes of various container types including vials and IV bags. This universal design eliminates the need for multiple specialized components (needles, adapters, piercers) while maintaining compatibility with different container types, thereby reducing material consumption and costs.
Solution Approach 2:
The invention merges the functions of the syringe tip and needle into a single integrated component. The beveled tip performs both the penetration function previously requiring separate needles and the fluid transfer function, eliminating the need for additional components and reducing overall material consumption.
3Adaptability or versatility
If additional components are used for drawing up medicines, then the syringe can access substances in various containers, but device complexity increases
Solution Approach 1:
The invention extracts and removes the separate needle component from the syringe system. The syringe tip itself is modified with a beveled end to perform the penetration function, reducing the number of components from multiple separate parts (syringe, needle, adapter) to a simpler integrated unit.
Solution Approach 2:
The invention combines the penetration function and fluid transfer function into a single integrated syringe tip with a beveled end. This merging of functions eliminates the need for separate needles and adapters, reducing device complexity while maintaining the ability to access substances in various containers.

AI summary
Disclosed here are syringe assemblies that include a modified syringe tip to penetrate a subject to obtain or administer a substance. The syringe system consists of a syringe body with or without a modified syringe tip with a standard or modified plunger. The modified syringe tip or modified plunger protrusion can penetrate a subject, such as the skin of a patient or a membrane on sealing a container containing medicine, or a seal of an empty vial.
