Adhesive Sensor Strip Layout for Continuous SSI Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for monitoring surgical site infections (SSIs) are imprecise and cumbersome, and integrating sensors into medical dressings complicates disposal and increases costs due to the need for hazardous waste management.
Innovation Solution
An adhesive sensor strip with a longitudinal extension larger than its lateral extension, comprising sensors for infection monitoring, is used in conjunction with a separate medical dressing, allowing precise sensor placement and prolonged use without interfering with wound healing, and facilitating easy data transmission and dressing changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are integrated into medical dressings, then infection monitoring capability is improved, but disposal complexity increases due to hazardous waste classification
Solution Approach 1:
The system is divided into two independent parts: a reusable sensor strip containing all electronic components and sensors, and a separate disposable medical dressing. This segmentation allows the sensor strip to be reused across multiple patients while only the dressing is discarded, eliminating hazardous waste issues while maintaining continuous monitoring capability.
Solution Approach 2:
The electronic components and sensors are extracted from the medical dressing and placed on a separate adhesive sensor strip. This extraction removes the hazardous elements from the disposable dressing, allowing the dressing to be treated as regular medical waste while the sensor strip is reused and properly managed.
2Reliability
If sensors are integrated into medical dressings, then infection monitoring capability is improved, but manufacturing cost increases
Solution Approach 1:
By separating the expensive sensor strip from the disposable dressing, the system allows bulk manufacturing and reuse of the sensor component, amortizing its cost over multiple uses. The dressing can be manufactured more simply and cheaply without electronic components, reducing overall manufacturing costs.
3Reliability
If sensors are integrated into medical dressings, then continuous monitoring is improved, but sensor placement precision becomes more difficult
Solution Approach 1:
The sensor strip is designed as a separate, flexible component that can be precisely positioned on the skin before the dressing is applied. This allows medical personnel to optimize sensor placement on the sensor strip itself, which then adheres to the skin in the correct position, ensuring accurate monitoring without interfering with wound healing.
4Duration of action of moving object
If sensors remain on skin for prolonged time, then monitoring continuity is improved, but patient discomfort increases
Solution Approach 1:
The sensor strip is designed as a thin, flexible, adhesive component that can remain on the skin for extended periods without causing irritation. The separate dressing can be changed regularly for hygiene while the sensor strip remains in place, providing continuous monitoring without prolonged discomfort from a single dressing change.
