Visit Duration Control System for ICU Stress Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current visiting policies in intensive care units (ICUs) and for young mothers do not effectively quantify or manage physiological stress caused by prolonged visits, which can endanger the health of patients or mothers due to lack of scientifically accepted methods for measuring arousal and stress.
Innovation Solution
A visit duration control system that uses sensors to monitor physiological parameters such as skin conductance and heart rate variability, with a processor to determine cumulative stress levels and issue warning signals when thresholds are exceeded, integrated into wearable devices or separate monitoring systems to manage visit duration and prevent excessive stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If unrestricted visitation is implemented in ICU, then family support and patient comfort are improved, but physiological stress and health risks to patients increase
Solution Approach 1:
The system continuously monitors physiological parameters (heart rate, skin conductance, temperature) and provides real-time feedback about stress levels to healthcare providers, enabling dynamic adjustment of visitation policies based on actual patient response rather than fixed restrictions
Solution Approach 2:
The system changes the state of visitation control from static (restricted/unrestricted) to dynamic by monitoring physiological parameters and adjusting visitation recommendations based on real-time stress level measurements
2Ease of operation
If prolonged visits are allowed to young mothers, then social support and emotional well-being are improved, but physiological stress and recovery complications increase
Solution Approach 1:
The system establishes baseline physiological parameters before visits begin and sets predetermined stress thresholds in advance, allowing proactive management of visit duration before harmful stress levels are reached
Solution Approach 2:
Real-time monitoring of physiological parameters during visits provides continuous feedback to both mothers and visitors about stress levels, enabling informed decisions about visit continuation or termination
3Reliability
If physiological stress monitoring is implemented, then patient health protection is improved, but device complexity and measurement requirements increase
Solution Approach 1:
The system uses standard, multi-functional physiological sensors already common in healthcare settings (heart rate monitors, skin conductance sensors) rather than specialized equipment, reducing complexity while maintaining health protection capabilities
Solution Approach 2:
The processor acts as an intermediary that simplifies complex physiological data into actionable stress level indicators and recommendations, bridging the gap between complex measurements and simple clinical decisions

AI summary
A visit duration control system comprises a sensor (10) for sensing one or more physiological parameters of a person over time allowing the quantification of stress load of said person, a visit detector (20) for indicating the start of a third party's visit to said person, a processor (30) for determining said person's stress load from said one or more physiological parameters during said third party's visit and a signaling unit (40) for issuing a warning signal if said stress load exceeds a predetermined level.
