Wound Dressing Sensor Display for Real-Time Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound dressings lack a direct and easy method to provide status information on wound healing and dressing saturation, making it difficult to determine when to replace them, especially in cases of unforeseen complications like 'gel blocking' and high local moisture content.
Innovation Solution
A wound dressing with integrated sensors and a display that receives and presents data on moisture, temperature, pressure, and pH levels, allowing for timely indication of saturation and potential complications, thereby facilitating informed decision-making on dressing replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wound dressing is used to cover a wound, then the wound is protected from further harm and can heal, but there is no direct method to monitor wound status and dressing saturation
Solution Approach 1:
The patent incorporates sensors that continuously monitor wound conditions (moisture, temperature, pH) and provide real-time feedback through a display interface. This feedback mechanism allows users to monitor wound status and dressing saturation levels without removing the dressing, resolving the information loss problem while maintaining wound protection.
Solution Approach 2:
The patent introduces an intermediary sensing system between the wound and the user. Sensors act as mediators that detect physiological parameters and transmit this information to the user interface, enabling indirect monitoring of wound status without direct exposure to the wound environment.
2Object-affected harmful factors
If a wound dressing is applied to absorb exudate, then the wound is protected from leakage, but it becomes difficult to determine when replacement is needed
Solution Approach 1:
The patent employs moisture sensors that provide real-time feedback on exudate absorption levels. The display interface shows the current saturation status, allowing users to immediately determine when the dressing needs replacement without having to physically assess the wound or guess based on time elapsed.
Solution Approach 2:
The patent replaces manual mechanical assessment (visual inspection, physical touch) with electronic sensing systems. Sensors electronically detect moisture levels and transmit this data to the display, eliminating the need for users to physically examine the dressing or wound to determine saturation status.
3Measurement precision
If a wound dressing monitors multiple parameters (moisture, temperature, pressure, pH), then comprehensive wound status is achieved, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional sensing system where multiple sensors work together to provide comprehensive wound monitoring. The integrated design allows a single system to measure moisture, temperature, pressure, and pH levels, achieving high measurement precision without requiring separate independent monitoring devices for each parameter.
