Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reduced-pressure treatment systems for subcutaneous tissue sites face limitations in effectively applying and managing reduced pressure, particularly in promoting tissue growth and healing, especially in complex tissue conditions such as bone fractures and osteoporosis.
Innovation Solution
A system comprising a manifold with multiple conduits, each having apertures for fluid communication with a reduced-pressure source, allowing for the delivery of reduced pressure to a subcutaneous tissue site, along with a secondary conduit forming an interior space for fluid communication and purging functions, enhancing the application and management of reduced pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single conduit is used to apply reduced pressure, then the device complexity is low, but the effectiveness of tissue growth promotion and healing is insufficient
Solution Approach 1:
The manifold is divided into multiple conduits (first conduit for reduced pressure delivery, second conduit for fluid delivery, third conduit for exudate removal) that can be independently configured and positioned. Each conduit serves a specific function in the tissue treatment process, allowing optimized placement and function while maintaining manageable complexity through modular design
Solution Approach 2:
The manifold structure integrates multiple functions into a single device: applying reduced pressure via first conduit, delivering therapeutic fluids via second conduit, and removing exudates via third conduit. This multi-functional approach enhances treatment effectiveness while consolidating what could be separate devices into one integrated manifold system
2Duration of action of stationary object
If reduced pressure is applied continuously, then tissue growth is consistently promoted, but exudates and bacteria accumulate requiring frequent system purging
Solution Approach 1:
The reduced pressure application operates continuously through the first conduit to consistently promote tissue growth and healing. The continuous negative pressure maintains optimal conditions for tissue regeneration throughout the treatment period
Solution Approach 2:
The third conduit is specifically designed to extract and remove harmful exudates and bacteria from the treatment site. This separate extraction pathway prevents accumulation of harmful substances while allowing the reduced pressure therapy to continue uninterrupted, effectively separating the therapeutic function from the waste removal function
3Adaptability or versatility
If multiple conduits are integrated in a single manifold, then fluid communication and purging functions are enhanced, but the manufacturing complexity increases
Solution Approach 1:
The manifold structure employs a nested configuration where conduits are positioned concentrically or in closely integrated arrangements. The first, second, and third conduits are arranged to share common pathways and connection points, allowing complex multi-conduit functionality to be achieved through space-efficient nesting rather than separate discrete components
Solution Approach 2:
Multiple conduit functions are merged into a single integrated manifold body that provides common mounting, sealing, and connection infrastructure. The manifold combines reduced pressure delivery, fluid injection, and exudate removal capabilities in one manufactured component, reducing the number of separate parts and assembly steps required
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively accelerates tissue growth, promotes healing, and improves bone density by consistently and variably delivering reduced pressure, facilitating the removal of exudates and bacteria, and stimulating tissue growth for wound healing and tissue transplantation.
