Antiseptic Applicator With Sliding Container and Sealing Plug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antiseptic applicators require complex actuation mechanisms, often necessitating two hands and special handling, and can impede the free flow of antimicrobial solutions due to puncturing or frangible ampoule designs, leading to complications during shipping and use.
Innovation Solution
A compact, ergonomically designed antiseptic applicator with a mechanical stop and a sealing plug that allows one-handed actuation, featuring a sliding container with orifices that provide fluid communication only upon intentional release, enabling controlled release of the solution without premature discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a puncturing means or frangible ampoule is used to release the solution, then the solution can be released from the sealed container, but the flow of solution is impeded by the puncture spike or broken ampoule components
Solution Approach 1:
The invention removes the harmful puncture spike and frangible ampoule components from the system. Instead of using a puncturing means, the solution is released through a clean opening mechanism where the plunger simply pushes the solution through the needle-free nozzle, eliminating components that would impede flow.
Solution Approach 2:
The invention converts the potential harm of broken components impeding flow into a benefit by designing a system where the release mechanism itself (the plunger and nozzle assembly) is streamlined to promote free flow. The mechanical advantage of the plunger is used to create positive pressure that drives solution flow without any obstructing remnants.
2Reliability
If preventive measures are added to prevent inadvertent puncturing, then accidental discharge is reduced, but the device complexity and handling difficulty increase
Solution Approach 1:
The invention incorporates a safety feature where the plunger is pre-loaded in a retracted position and the needle-free nozzle is initially sealed or covered. The user must intentionally activate the device by pushing the plunger, which automatically breaks the seal and releases the solution. This preliminary safety configuration prevents accidental discharge while maintaining simple one-handed operation.
3Reliability
If a mechanical stop or retention mechanism is used to secure the container, then premature release is prevented, but the actuation mechanism becomes more complex
Solution Approach 1:
The invention uses a self-locking plunger mechanism where the plunger itself provides the retention function. The plunger is spring-loaded or mechanically biased to remain in a retracted, safe position until intentionally actuated. The user's pushing action on the plunger head automatically overcomes the retention force and initiates solution release, eliminating the need for separate mechanical stops or complex actuation mechanisms.

Function Achieved in This Case
Enables efficient, one-handed application of antimicrobial solutions without impediments to flow, reducing the risk of accidental discharge and simplifying handling and use, while maintaining effective sterilization capabilities.
Implementation Method 1
an interior of the container is placed in fluid communication with the application member by way of a fluid conduit that is formed through the plug from the container to the fluid chamber when the container is actuated toward the head portion to bring the one or more orifices into fluid communication with the container

AI summary
An applicator assembly includes a head portion having a proximal end, a distal end, and an interior portion defining a fluid chamber, a container slidably coupled to the head portion, a plug sealing an end of the container, an application member attached to the distal end, and one or more orifices formed through a surface of the plug, wherein the plug is mounted in the interior portion of the head portion and an interior of the container is placed in fluid communication with the application member by way of a fluid conduit that is formed through the plug from the container to the fluid chamber when the container is axially translated toward the head portion to bring the one or more orifices into fluid communication with the container.
