Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing negative-pressure wound therapy (NPWT) and instillation therapy systems are customized to varying wound types, leading to high equipment and training costs due to the need for diverse controllers, operator interfaces, and communication interfaces, which lack standardization.
Innovation Solution
A system for wirelessly controlling a dressing interface that integrates sensors within the dressing to measure pressure, temperature, and pH, allowing for standardized operation and communication with a central controller, enabling accurate monitoring and control of negative-pressure therapy and instillation therapy across different wound types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If diverse customized NPWT systems are used for different wound types, then treatment effectiveness is improved, but equipment cost and training cost increase significantly
Solution Approach 1:
The patent implements a universal controller that can interface with multiple types of wound dressings through automatic detection. The controller uses RFID tags and communication interfaces to identify dressing type and automatically configure appropriate therapy parameters, allowing one controller to serve multiple wound treatment functions without requiring separate specialized equipment for each wound type
Solution Approach 2:
The system automatically adjusts therapy parameters such as negative pressure levels, instillation volumes, and treatment durations based on the detected wound dressing type. The controller modifies operational parameters dynamically to match the specific requirements of different wound conditions while using the same hardware platform
2Device complexity
If standardized controllers and interfaces are implemented across all NPWT systems, then equipment cost and training cost are reduced, but the ability to customize treatment for specific wound types may be compromised
Solution Approach 1:
The wound dressing includes an embedded RFID tag that automatically provides identification and configuration information to the controller. The system performs self-configuration by reading the RFID tag data and automatically setting appropriate therapy parameters, eliminating the need for manual customization while maintaining treatment specificity
Solution Approach 2:
The controller continuously monitors therapy parameters and dressing status through communication interfaces, receiving feedback from the wound dressing about its type, condition, and treatment progress. This feedback loop enables the standardized controller to automatically adjust settings to match the specific wound treatment requirements
3Reliability
If multiple specialized communication interfaces are used for different dressings, then precise control for each wound type is achieved, but system complexity and integration difficulty increase
Solution Approach 1:
The controller employs a universal communication interface that can detect and communicate with various types of wound dressings through a single standardized connection. The interface automatically identifies the dressing type and establishes appropriate communication protocols, eliminating the need for multiple specialized interfaces while maintaining precise control capabilities
