Patient Visualization System for Pressure Injury Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer pressure monitors are inadequate in providing real-time, electronic delivery and display of actionable data to effectively prevent pressure injuries, as they do not adequately empower medical staff to identify and respond to critical pressure injury situations, especially due to insufficient tracking and monitoring of pressure and body positioning.
Innovation Solution
A patient visualization system that includes a processor communicatively coupled to a pressure sensor device, which receives and analyzes pressure sensor data to calculate pressure experienced by body areas over time, displays interventions, and provides graphical representations of pressure history and repositioning data to caregivers, enabling proactive offloading decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional pressure monitoring methods are used, then device complexity is reduced, but measurement precision and information completeness deteriorate
Solution Approach 1:
The pressure monitoring system is segmented into multiple independent pressure sensors distributed across the support surface, each measuring pressure at specific locations. This segmentation allows for precise localized pressure measurement while keeping each sensor unit simple and manageable.
Solution Approach 2:
A processor acts as an intermediary between the pressure sensors and the user interface, collecting data from multiple sensors, calculating body area pressure over time, and presenting processed information to caregivers. This intermediary layer manages the complexity of data aggregation and analysis.
2Loss of information
If real-time pressure tracking and visualization is implemented, then information completeness is improved, but device complexity increases
Solution Approach 1:
The system provides continuous feedback to caregivers through a user interface that displays pressure history, current pressure status, and visual representations of body areas at risk. This feedback loop enables proactive intervention by presenting actionable information about pressure exposure over time.
Solution Approach 2:
The system adds the time dimension to pressure monitoring by calculating and displaying pressure experienced by body areas over specified periods. This temporal dimension transforms static pressure readings into dynamic pressure history data, enabling trend analysis and predictive prevention.
3Reliability
If comprehensive pressure monitoring and intervention tracking are implemented, then reliability of pressure injury prevention is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically performs data collection, processing, and analysis without requiring manual intervention. Pressure sensors continuously monitor and the processor automatically calculates body area pressure and generates visualizations, reducing the operational burden on caregivers while maintaining high reliability.
Solution Approach 2:
The system performs preliminary analysis of pressure data to identify potential pressure injury risks before they manifest as actual injuries. By calculating pressure exposure over time and providing early warnings, the system enables proactive prevention rather than reactive treatment.

AI summary
A patient visualization system having a processor, communicatively coupled to a pressure sensor device to periodically receive pressure sensor data experienced by a subject at locations on the pressure sensor device. The processor programmed to receive input indicative of an intervention resulting in a pressure lowering of a body area of the subject during a first high-pressure situation at a first time; and responsive to determining a second high-pressure situation at the body area of the subject at a second time later than the first time, display an indication of the input of the intervention in connection with the first high-pressure situation.
