Patient Bed Pressure Injury Monitoring via Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring patients in beds to prevent pressure injuries are not targeted enough, leading to inefficient resource allocation and potential unnecessary movement of patients.
Innovation Solution
A computer-implemented method and system that analyzes images of patients in beds to predict pressure scores for specific contact regions, providing targeted indications for patient or caregiver action to reduce pressure injury risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general monitoring of all patients is performed, then pressure injury prevention coverage is improved, but resource allocation efficiency deteriorates
Solution Approach 1:
The system applies different monitoring intensities and interventions to different body regions based on their specific pressure injury risk characteristics. High-risk areas such as sacrum, heels, and occiput receive focused monitoring and earlier intervention, while lower-risk areas receive standard monitoring, thereby optimizing resource allocation while maintaining comprehensive prevention coverage.
Solution Approach 2:
The system dynamically adjusts monitoring parameters such as pressure thresholds, monitoring frequency, and alert sensitivity based on individual patient risk factors, body composition, and real-time pressure measurements. This allows the system to maintain high prevention coverage while adapting resource consumption to actual patient needs rather than applying uniform monitoring to all patients.
2Stress or pressure
If frequent patient movement is performed, then pressure distribution is improved, but patient comfort and potential harm deteriorate
Solution Approach 1:
The system performs preliminary assessment of pressure distribution patterns and predicts future pressure injury risks before actual injury occurs. By identifying high-risk contact regions in advance, the system can prompt targeted position changes or interventions only when and where needed, rather than requiring frequent universal patient movement, thereby maintaining good pressure distribution while minimizing unnecessary disturbance to patients.
Solution Approach 2:
The system continuously monitors pressure distribution and provides real-time feedback to caregivers and patients. When pressure in specific high-risk areas approaches dangerous thresholds, the system generates alerts prompting localized position adjustments. This feedback mechanism ensures adequate pressure redistribution while allowing patients to remain in comfortable positions longer, reducing unnecessary movement-related harm.

AI summary
A computer-implemented method for targeted monitoring of a patient in a bed comprises: receiving an image of the bed; predicting, based on a posture of the patient in the image, a pressure score for one or more contact regions between the patient and the bed; and providing an indication of the pressure score for the one or more contact regions.
