Solution Overview
Problem
Existing tissue treatment systems, particularly those utilizing negative-pressure therapy, lack effective mechanisms to enhance tissue growth and wound healing through macrostrain application and fluid management.
Innovation Solution
The introduction of a dressing interface that generates macrostrain at the tissue site via flanges or flaps under negative pressure, combined with a manifold for fluid distribution and a system for instillation therapy, which includes a macrostrain device and a sealing member to apply controlled negative pressure and fluid delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If negative-pressure therapy is applied to a tissue site, then tissue growth and wound healing are enhanced, but the existing systems lack effective mechanisms for macrostrain application and fluid management
Solution Approach 1:
The patent combines negative-pressure therapy with macrostrain application by integrating a bolster body with flanges that can be coupled to a dressing interface. This merging allows the system to simultaneously provide negative pressure for tissue growth enhancement and macrostrain through the flange mechanism, resolving the contradiction by unifying previously separate functions into a single integrated device.
Solution Approach 2:
The bolster body device is designed to perform multiple functions: it provides negative-pressure therapy, applies macrostrain through its flanges, and facilitates fluid management through integration with the dressing interface. This multi-functionality addresses the technical contradiction by making a single device capable of handling multiple therapeutic requirements without increasing overall system complexity.
2Productivity
If flanges or flaps are used to generate macrostrain under negative pressure, then tissue development is promoted, but the device structure becomes more complex
Solution Approach 1:
The bolster body is segmented into distinct functional components: a main body portion and detachable flanges. This segmentation allows the macrostrain-generating flanges to be separated from the negative-pressure delivery system, simplifying the overall structure while maintaining the ability to promote tissue development through macrostrain application.
Solution Approach 2:
The flanges are designed to be movable relative to the bolster body, allowing dynamic adjustment during use. This dynamic capability enables the flanges to generate macrostrain as needed while maintaining a relatively simple structure, as the complexity is introduced only when and where needed during the therapeutic process rather than being permanently integrated.
3Reliability
If a sealing member is added to apply controlled negative pressure and fluid delivery, then therapy effectiveness is improved, but the system complexity increases
Solution Approach 1:
The sealing member acts as an intermediary component between the bolster body and the dressing interface. It provides a controlled interface for negative pressure application and fluid delivery without requiring direct integration of complex mechanisms into the main device structure. This intermediary approach improves therapy effectiveness while minimizing the increase in overall system complexity.
