Blood Pump Alarm Management via Color-Coded Visual Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional perfusion systems during cardiopulmonary bypass surgeries require manual and frequent adjustments by perfusionists to manage various parameters and alarm conditions, necessitating improved mechanisms for safer, more accurate, and quicker control of alarm conditions.
Innovation Solution
A user interface with a touch screen that displays color-coded alarm conditions and management icons, using red and yellow indicators to guide users in managing alarms, providing clear visual and auditory cues for alerting and addressing alarm conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manual monitoring and adjustment of perfusion system parameters is performed, then the system can be controlled, but the speed and accuracy of alarm management is reduced
Solution Approach 1:
The patent replaces manual mechanical monitoring and adjustment with an automated control system that uses sensors, processors, and actuators to automatically monitor parameters and adjust pump speeds, thereby increasing the speed and accuracy of alarm management while reducing manual intervention requirements
Solution Approach 2:
The perfusion system is designed to self-monitor and self-adjust by automatically detecting parameter deviations and correcting them without requiring continuous manual input, allowing the system to manage its own operation and respond quickly to alarm conditions
2Loss of time
If multiple parameters are monitored manually, then system control is maintained, but the time required for alarm management increases
Solution Approach 1:
The patent combines multiple parameter monitoring functions into a single integrated control system that simultaneously tracks flow rate, pressure, temperature, and other parameters, allowing the system to manage all parameters together rather than individually, thereby reducing total monitoring time
Solution Approach 2:
The system performs preliminary monitoring and prediction of parameter deviations before actual alarm conditions occur, allowing proactive adjustment and preventing alarm situations from developing, thus reducing the time required to respond to actual alarms
3Reliability
If frequent manual adjustments are made, then parameter balance is maintained, but the risk of human error increases
Solution Approach 1:
The patent implements continuous feedback loops where sensors monitor system parameters in real-time and automatically adjust pump speeds based on detected deviations, creating a closed-loop control system that maintains parameter balance without requiring manual intervention and eliminates human error
Solution Approach 2:
Manual mechanical adjustments are replaced with automated electronic control that uses processors and actuators to precisely regulate pump speeds, thereby maintaining parameter balance with higher accuracy and eliminating the variability and errors associated with manual operation
