Wound Dressing pH Sensor System for Infection Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound monitoring systems do not effectively monitor the status of wounds and wound dressings without removing the dressings, leading to unnecessary changes and potential infections, as they fail to provide real-time data on pH levels and other vital signs.
Innovation Solution
A system comprising a wound dressing with integrated sensing devices, including a pH meter, network interface hardware, and a controller that determines if an infection is likely by analyzing pH level changes over time and alerts healthcare providers through a network interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If wound dressings are frequently changed to monitor wound status, then wound status can be checked, but heat loss increases and infection risk increases
Solution Approach 1:
The patent replaces the mechanical action of removing dressings to visually inspect wounds with electronic sensing devices that measure pH levels, temperature, and moisture content. These sensors transmit data wirelessly to healthcare providers, allowing continuous monitoring without physical disturbance to the wound-dressing system.
Solution Approach 2:
The patent introduces sensing devices as intermediaries between the wound and the healthcare provider. These devices are integrated into the dressing and act as mediators that collect wound status data (pH, temperature, moisture) and transmit it externally, eliminating the need for direct visual inspection that requires dressing removal.
2Loss of information
If wound dressings are frequently changed to monitor wound status, then wound status can be checked, but infection risk increases
Solution Approach 1:
The patent replaces the mechanical action of removing dressings to visually inspect wounds with electronic sensing devices that measure pH levels, temperature, and moisture content. These sensors transmit data wirelessly to healthcare providers, allowing continuous monitoring without physical disturbance to the wound-dressing system.
Solution Approach 2:
The patent enables continuous monitoring of wound status through integrated sensors that operate throughout the entire dressing wear period. This continuous data collection allows healthcare providers to detect infection signs (such as pH changes) in real-time without interrupting the protective function of the dressing.
3Reliability
If sensing devices are integrated into wound dressings to monitor pH levels, then infection detection improves, but device complexity increases
Solution Approach 1:
The patent integrates multiple sensing functions (pH measurement, temperature sensing, moisture detection) into a single dressing system. The controller processes multiple types of data from different sensors to comprehensively assess wound status and detect infection signs, making the system multi-functional rather than requiring separate devices for each parameter.
Solution Approach 2:
The patent combines the sensing devices, controller, and communication components into an integrated unit that is incorporated within the dressing structure. This merging of components simplifies the overall system architecture compared to using separate monitoring devices, while still providing comprehensive wound status monitoring capabilities.

AI summary
A system for monitoring a wound includes a wound dressing configured to cover a wound surface of the wound, one or more sensing devices attached to the wound dressing, a network interface hardware, and a controller. The controller includes one or more processors, and one or more memory modules storing computer readable and executable instructions. The controller receives data measured by the one or more sensing devices, determines whether an infection is likely to occur based on the data measured by the one or more sensing devices, and outputs an alert, through the network interface hardware, in response to determining that the infection is likely to occur.
