Reagent Storage Section for Continuous Sample Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample analyzers require multiple reagent containers of the same type to continue measurement when one becomes empty, and users cannot determine the optimal timing for reagent container replacement, leading to potential interruptions and inefficiencies.
Innovation Solution
A sample analyzer with a reagent storage section that allows continuous measurement by transferring reagents from a reagent container to the storage section, which then supplies the measurement section, and outputs messages for reagent replacement based on remaining amounts, enabling users to replenish reagents without interrupting the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple reagent containers of the same type are connected to continue measurement when one becomes empty, then measurement continuity is improved, but device complexity increases
Solution Approach 1:
The patent introduces a reagent storage section as an intermediary component between the reagent container and the measurement section. This storage section temporarily holds reagent and enables continuous supply to the measurement section even when the reagent container is empty, thereby maintaining measurement continuity without requiring multiple reagent containers to be connected simultaneously
Solution Approach 2:
The reagent supply system is segmented into distinct functional sections: the reagent container, the reagent storage section, and the measurement section. This segmentation allows the storage section to independently buffer reagent supply, decoupling the measurement continuity from the reagent container status and simplifying the overall system architecture
2Device complexity
If reagent container replacement timing is not indicated, then system operation is simplified, but loss of information occurs
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors the reagent remaining amount in the reagent storage section and provides information to the user about the number of samples that can be measured without replacement. This feedback loop enables users to make informed decisions about replacement timing without adding complex operational procedures
Solution Approach 2:
The system automatically calculates and displays the number of measurable samples based on the remaining reagent amount, eliminating the need for users to manually track or calculate replacement timing. The system serves itself by providing this information autonomously, maintaining simple operation while preventing information loss
3Loss of substance
If reagent transfer is suspended when storage section is low, then reagent wastage is prevented, but measurement interruption occurs
Solution Approach 1:
The system performs preliminary actions by notifying the user in advance about the reagent remaining amount and the number of samples that can be measured. This early notification allows users to prepare for replacement before the storage section is depleted, preventing both reagent wastage and measurement interruptions through proactive planning

Function Achieved in This Case
Enables continuous sample measurement without the need for multiple reagent containers of the same type, allows timely reagent replenishment, and prevents wastage by suspending transfers before the storage section is empty, thus maintaining measurement integrity.
Implementation Method 1
a transfer unit that transfers the reagent from the reagent container to the reagent storage section and then from the reagent storage section to the measurement section

AI summary
A sample analyzer is provided that does not require a plurality of reagent containers containing the same type of reagent to be connected, that can continue measurement even when a reagent container becomes empty, and that allows the timing of replacement of the reagent container to be recognized suitably. A reagent storage section is provided that is connected to a reagent container containing a reagent through a fluid channel and that stores the reagent transferred from the reagent container. A message for prompting replacement of the reagent container is outputted when it is detected that the remaining amount in the reagent container is a predetermined amount or less. A message for prompting to suspend sample measurement in the measurement section is outputted when it is detected that the remaining amount in the reagent storage section is a predetermined amount or less.
