Multi-Ampoule Antiseptic Applicator With Retractable Actuators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antiseptic applicators lack the ability for users to independently control the rupture of multiple ampoules and have a profile that makes it difficult to reach all areas of a patient, especially when actuators increase the overall size.
Innovation Solution
An applicator assembly with a container and multiple ampoules that allows independent fracture and release of liquids using actuators, featuring a design that reduces the profile when actuators are in a second position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple ampoules are included in the applicator assembly, then the versatility and controlled release capability are improved, but the device complexity increases
Solution Approach 1:
The applicator assembly is segmented into multiple independent ampoules, each capable of being fractured and releasing its contents independently. This segmentation allows the user to control the release of each ampoule separately, providing versatility in dosing and application while maintaining a relatively simple overall device structure.
2Ease of operation
If actuators are added to enable independent fracture of ampoules, then the ease of operation is improved, but the length of the applicator increases
Solution Approach 1:
The actuators are designed to be nested within or integrated into the container structure. When not in use, the actuators are positioned inside the container housing, minimizing the overall length of the applicator. When actuation is required, the actuators extend or move to engage the ampoules, providing ease of operation without permanently increasing the applicator's length.
3Ease of operation
If the actuator is positioned to fracture ampoules, then the ease of operation is improved, but the profile of the applicator increases making it difficult to reach all areas
Solution Approach 1:
The actuator is designed with dynamic positioning capability, allowing it to move between a retracted position (when not in use) and an extended position (when actuation is required). This dynamic design enables the applicator to maintain a compact profile for reaching difficult areas while still providing easy access to the fracture mechanism when needed.

AI summary
An applicator assembly includes a plurality of ampoules formed of a frangible material and containing liquid to be applied, a container having a proximal end, a distal end, and an interior portion defining a chamber adapted to receive the plurality of ampoules, an application member attached to the distal end of the container; and at least one actuator projecting from the container, wherein the at least one actuator is actuatable to independently fracture the plurality of ampoules, thereby independently releasing the liquid into the application member. The at least one actuator may be moveable from a first position to a second position, the applicator having a smaller profile when the actuator is in the second position than when the actuator is in the first position.
