Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extracorporeal circulatory support systems lack efficient mechanisms for dynamically controlling the infusion of supplements into blood based on real-time patient parameters, leading to suboptimal treatment outcomes.
Innovation Solution
The system integrates a processor, sensors, and fluid flow regulators to measure and adjust blood parameters by infusing supplemental fluids such as blood, saline, or medication, based on target values determined from patient profiles and real-time measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual monitoring and adjustment of blood parameters is used, then system complexity is reduced, but treatment precision and response time deteriorate
Solution Approach 1:
The system automatically monitors blood parameters through sensors and adjusts supplement infusion without manual intervention. The processor receives sensor signals, compares measured values to target values, and autonomously controls fluid flow regulators to maintain optimal blood parameters, enabling the system to serve itself.
Solution Approach 2:
The system implements continuous feedback control by measuring blood parameters with sensors, comparing actual values to target values from patient profiles, and adjusting supplement infusion rates accordingly. This closed-loop feedback mechanism ensures precise control while automatically adapting to changing patient conditions.
2Reliability
If continuous monitoring and adjustment is implemented, then treatment efficacy is improved, but energy consumption and operational complexity increase
Solution Approach 1:
The system maintains continuous monitoring of blood parameters and continuous adjustment of supplement infusion throughout the treatment process. Sensors continuously measure parameters, and the processor continuously regulates fluid flow to ensure blood conditions remain within optimal ranges without interruption.
Solution Approach 2:
The automated system performs all monitoring and adjustment functions autonomously without requiring continuous manual intervention or complex operational procedures, reducing operational complexity while maintaining treatment efficacy through self-regulation.
3Speed
If automated control systems are added, then response time is improved, but device complexity and cost increase
Solution Approach 1:
The system replaces manual mechanical adjustment with automated electronic control. Sensors electronically detect blood parameters, the processor computationally determines required adjustments, and electronic fluid flow regulators automatically modify supplement infusion rates, eliminating manual mechanical operations and enabling rapid response.
Solution Approach 2:
The automated feedback control system rapidly detects deviations from target blood parameters and immediately adjusts supplement infusion accordingly, achieving fast response times through continuous electronic monitoring and automatic regulation without manual intervention.
