Sample Processing Apparatus Reagent Authenticity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of non-genuine reagents in sample processing apparatuses, such as hemocytometers and smear preparing apparatuses, leads to unreliable analysis results, potentially causing adverse impacts on patient care due to inappropriate treatments or medications, as users may not be aware of the reduced reliability when using alternative products.
Innovation Solution
A sample processing apparatus and method that includes a controller to determine whether the auxiliary items, such as reagents, are appropriate for processing, and outputs processing results along with reliability information if the items are deemed inappropriate, ensuring users are informed of the analysis reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated reagents are used, then analysis reliability is improved, but device complexity increases due to verification systems
Solution Approach 1:
The system performs preliminary verification of reagent authenticity before analysis by checking authentication information (barcodes, RFID tags) on reagent containers. This preliminary action ensures that only verified reagents are used, guaranteeing analysis reliability while avoiding the need for complex verification during the analysis process itself.
Solution Approach 2:
The patent introduces an intermediary authentication system that mediates between the reagent and the analysis apparatus. This intermediary layer (authentication information on reagent containers) simplifies the verification process by providing a clear, standardized method for confirming reagent authenticity, reducing the overall system complexity while maintaining high reliability.
2Loss of information
If reagent authentication system is implemented, then information accuracy is improved, but device complexity increases
Solution Approach 1:
The reagent containers are equipped with self-contained authentication information (barcodes, RFID tags, authentication codes) that automatically provide verification data when scanned or read by the apparatus. This self-service approach ensures accurate information transmission without requiring complex manual verification procedures, maintaining information accuracy while minimizing added system complexity.
