Multi-site Wound Pressure Monitoring with Segmented Conduits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reduced pressure treatment systems for multiple tissue sites lack effective monitoring, leading to potential variations in pressure that can go unnoticed, causing detrimental effects such as delayed healing or graft failure, as only one conduit is typically monitored for pressure at a time.
Innovation Solution
A system that includes a reduced-pressure source, pressure management module, conduits for delivering and sensing pressure at multiple tissue sites, with each site having a sensing conduit and delivery conduit associated with it, allowing for real-time monitoring and adjustment of pressure to ensure consistent treatment across all sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single conduit is used to deliver reduced pressure to multiple tissue sites, then the device complexity is reduced, but the measurement precision of pressure at each tissue site deteriorates
Solution Approach 1:
The system divides the pressure delivery and monitoring function into separate segments: one conduit is dedicated for pressure delivery to multiple tissue sites, while separate sensing conduits are placed at each tissue site for independent pressure monitoring. This segmentation allows the single delivery conduit to maintain low complexity while the distributed sensing conduits enable precise local pressure measurement at each site.
2Measurement precision
If separate conduits are used for each tissue site, then the measurement precision of pressure at each site is improved, but the device complexity increases
Solution Approach 1:
The pressure delivery conduit serves multiple functions: it delivers reduced pressure to multiple tissue sites simultaneously and acts as a common distribution system. The sensing conduits, while separate for measurement precision, are designed with universal connection interfaces to the pressure management module, allowing standardized monitoring across all sites without proportionally increasing system complexity.
3Device complexity
If pressure is monitored at only one tissue site, then the device complexity is reduced, but the reliability of treatment across all sites deteriorates
Solution Approach 1:
The system implements feedback monitoring by placing sensing conduits at each tissue site that continuously measure local pressure and transmit data to the pressure management module. The module compares measured pressures against target pressure ranges and provides real-time feedback, automatically adjusting pressure delivery to maintain consistent treatment across all sites, thereby ensuring treatment reliability.
4Reliability
If real-time pressure monitoring is implemented at multiple sites, then the reliability of treatment is improved, but the device complexity increases
Solution Approach 1:
The system merges all sensing conduits into a single integrated pressure management module that consolidates data from multiple tissue sites. The module provides unified pressure regulation and monitoring capabilities, allowing multiple sensing points to be managed through a centralized control system rather than requiring separate control mechanisms for each site, thus reducing overall system complexity while maintaining reliable multi-site monitoring.
