Solution Overview
Problem
Current methods for processing blood samples in clinical diagnosis often result in incomplete clotting, leading to latent fibrin formation, which can cause analyzer malfunctions and provide incorrect results.
Innovation Solution
A method and system for setting a clotting start time and wait time for blood samples in a test system, allowing for automated transport to a centrifuge upon completion of clotting, ensuring reliable results by minimizing latent fibrin in serum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If blood samples are processed quickly to improve productivity, then processing speed increases, but clotting may be incomplete leading to latent fibrin formation and incorrect results
Solution Approach 1:
The system performs preliminary actions by automatically setting the clotting start time and calculating the required clotting wait time before processing begins. The controller pre-determines the optimal clotting duration based on sample characteristics and automatically initiates the clotting process, ensuring adequate clotting time is allocated before centrifugation and analysis, thus preventing latent fibrin formation while maintaining efficient workflow
Solution Approach 2:
The system implements feedback mechanisms by monitoring the clotting process through automated time tracking and sample status detection. The controller receives feedback on clotting progression and automatically adjusts the processing timeline, triggering centrifugation only when clotting is complete, thereby ensuring reliable results while optimizing processing speed through intelligent control
2Reliability
If manual monitoring of clotting time is used to ensure reliability, then clotting completeness improves, but labor requirements and operational complexity increase
Solution Approach 1:
The system enables self-service by automatically setting clotting start time, calculating required wait time, monitoring clotting progression, and triggering centrifugation without manual intervention. The test system autonomously manages the entire clotting process, eliminating the need for manual time tracking and monitoring while ensuring complete clotting through automated control mechanisms
Solution Approach 2:
The system replaces manual mechanical monitoring with automated electronic control. The controller uses electronic timing mechanisms, sensors, and automated decision-making algorithms to monitor and manage clotting time, substituting human operators with an automated control system that ensures reliable clotting completion while simplifying operations through automation
