Multi-Chamber Ampoule with Inversion Mixing for Wound Polymers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ampoules made of glass limit the type of contents that can be stored, as some chemical mixtures require mixing of multiple chemicals, which is difficult to achieve in a secure and efficient manner, especially in uncontrolled environments like battlefields or traumatic situations.
Innovation Solution
A novel ampoule design featuring a container with multiple chambers for storing different chemicals, a cap with a mixing member, and a tab-seal that can be removed to allow the contents to mix and exit, enabling polymerization reactions to occur on-site for wound treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass ampoules are used to store chemical mixtures, then sterility and stability of contents are maintained, but the ability to mix chemicals in uncontrolled environments is limited
Solution Approach 1:
The ampoule is divided into multiple separate chambers, each containing a different chemical component. This segmentation allows the chemicals to be stored separately in a sterile, stable environment while enabling easy mixing in the field by simply inverting the ampoule to allow the chemicals to mix through the narrow opening.
Solution Approach 2:
Multiple chambers are nested within the single ampoule structure, with each chamber containing a different chemical. The nested design allows multiple chemicals to be stored in a compact, sterile container while enabling their combination through simple inversion, eliminating the need for external mixing equipment.
2Reliability
If multiple separate ampoules are used to store different chemicals, then each chemical can be stored sterily, but additional apparatus and secure facilities are required for mixing
Solution Approach 1:
Multiple chemical storage chambers are merged into a single integrated ampoule structure. This consolidation eliminates the need for multiple separate ampoules and external mixing apparatus, as the chemicals can be mixed directly within the single ampoule by simple inversion, reducing overall device complexity while maintaining sterility.
Solution Approach 2:
The single ampoule structure serves multiple functions: it stores multiple chemicals separately, maintains sterility, and enables mixing through inversion. This multi-functionality eliminates the need for separate storage containers and mixing equipment, reducing the overall system complexity.
3Manufacturing precision
If chemicals are mixed before administration in a secure environment, then accurate mixture is achieved, but the ability to treat wounds in battlefield or traumatic situations is limited
Solution Approach 1:
The chemicals are pre-loaded into separate chambers within the ampoule in controlled manufacturing conditions, ensuring accurate formulation. The design then enables easy mixing in the field through simple inversion, bridging the gap between controlled manufacturing and field deployment without requiring secure facilities at the point of use.

AI summary
There is disclosed a wound treatment system having an ampoule with at least two chambers for housing a first and second-containing elastomer component respectively. The ampoule is closed at one end and is sealed at the other end via a tab-seal. Once the tab-seal is removed, a cap is secured to the anterior end of the ampoule via engagement members. The cap is configured with a mixing member found in a channel that runs the length of the cap. As a user applies a lateral force to the ampoule, the first and second-containing elastomer components are mixed by the mixing member to form a skin treatment composition that is applied to the skin of a user for treating a burn, a wound, a scar or a keloid.
