Sample Analyzer Reagent Container Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sample analyzers face challenges in accurately determining when to replace reagents, as they often automatically move reagents to a pick-up position based on insufficient quantities, failing to account for reasons other than reagent insufficiency, such as expired validity dates.
Innovation Solution
The implementation of a system that allows for manual specification of reagent replacement through a graphical user interface, displaying reagent information, including residual amounts and expiration dates, and moving reagents to a pick-up position only when explicitly selected for replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the sample analyzer automatically moves reagent containers to the pick-up position when residual reagent is insufficient, then the system maintains automated reagent management, but reagent containers that need replacement for other reasons (e.g., expired validity date) cannot be moved to the pick-up position
Solution Approach 1:
The system dynamically adjusts the reagent replacement decision process by allowing transition from fully automatic mode to manual selection mode. The controller can switch between automatically determining replacement based on residual amount and allowing manual specification based on multiple criteria including expiration date, enabling the system to adapt to different operational needs
Solution Approach 2:
The controller acts as an intermediary between the automatic detection system and the manual replacement decision. It receives both automatic residual amount detection and manual user input, integrates these information sources, and makes the final decision on whether to move the reagent container to the pick-up position
2Adaptability or versatility
If the system allows manual specification of reagent replacement, then reagent replacement flexibility is improved, but the complexity of the control system increases
Solution Approach 1:
The system provides self-service functionality through the graphical user interface that displays reagent information and allows operators to easily specify replacement needs. The controller automatically processes the manual selection and executes the replacement operation, reducing the burden on operators while maintaining simplicity
3Measurement precision
If the sample analyzer displays detailed reagent information including residual amounts and expiration dates, then reagent management accuracy is improved, but the complexity of the user interface increases
Solution Approach 1:
The reagent information display is segmented into distinct components: reagent container identification, residual amount indicators, expiration date information, and replacement status. This segmentation allows the interface to present comprehensive information in an organized, easy-to-navigate manner without overwhelming the user

AI summary
The present invention is to present a sample analyzer which is able to move a reagent container containing a reagent which a user desires to replace to a pick up position. The sample analyzer comprises: a holding section comprising a plurality of holding regions for holding reagent containers, and being capable of moving the holding regions; analyzing means for analyzing a measurement sample prepared by mixing a sample and the reagent contained in the reagent container held by the holding section; receiving means for receiving a specification of a holding region from the plurality of holding regions to replace or add a reagent; and control means for controlling the holding section so as to move the specified holding region to a replacement-addition position at which the reagent is replaced or added, when the receiving means receives the specification of the holding region.
