Automatic Analysis Apparatus Water Blank Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analysis apparatuses face inefficiencies in collecting water blank data, as they often require user intervention and reduce measurement processing performance, especially when multiple reaction vessels need to be checked for abnormalities.
Innovation Solution
The apparatus automatically collects water blank data by dispensing water into unused reaction vessels and applying photometry, allowing for continuous measurement processing without user intervention by determining which vessels to use based on predetermined conditions such as elapsed time, abnormal readings, or reagent usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water blank data collection is performed by dispensing cleaning water to a designated reaction vessel, then water blank data can be collected for hardware abnormality diagnosis, but the measurement processing performance is reduced and user intervention is required
Solution Approach 1:
The system automatically determines which reaction vessels need water blank data collection based on predetermined conditions (elapsed time, abnormal readings, reagent usage) and performs the data collection without user intervention. The control unit autonomously selects target reaction vessels and triggers the water dispensing and photometry processes, eliminating the need for manual user input while maintaining reliable hardware abnormality detection
Solution Approach 2:
The system proactively collects water blank data from reaction vessels that meet predetermined conditions before they are needed for specimen measurement. By monitoring conditions such as elapsed time since last use, abnormal photometry readings, and reagent dispensing history, the system identifies and collects data from potential problem vessels in advance, preventing measurement delays and maintaining high productivity
2Extent of automation
If a particular reaction vessel is designated for water blank data collection, then water blank data can be collected automatically, but the designated vessel cannot be used for specimen measurement
Solution Approach 1:
Instead of designating a single reaction vessel for water blank data collection, the system segments the task across multiple reaction vessels. The control unit evaluates predetermined conditions for each vessel individually and selects appropriate target vessels from the plurality of reaction vessels. This segmentation allows the system to collect water blank data from multiple vessels without permanently dedicating any single vessel to this purpose, thereby maintaining full specimen measurement capacity
Solution Approach 2:
The system dynamically selects which reaction vessels to use for water blank data collection based on real-time conditions such as elapsed time, photometry readings, and reagent usage. Rather than a static designation, the target reaction vessels are determined flexibly according to current system state, allowing optimal allocation between water blank data collection and specimen measurement needs
3Reliability
If water blank data is collected from multiple reaction vessels, then comprehensive hardware abnormality detection is achieved, but the time and resources required for data collection increase
Solution Approach 1:
The system performs water blank data collection only from reaction vessels that meet predetermined conditions, rather than from all vessels. By applying thresholds for elapsed time, photometry reading abnormalities, and reagent dispensing history, the system identifies and collects data only from vessels that are likely to exhibit hardware abnormalities. This partial action approach achieves comprehensive abnormality detection while minimizing the number of vessels processed, thereby reducing time and resource consumption

AI summary
An automatic analysis apparatus of an embodiment includes a holder, a first dispenser, a second dispenser, a detector, a memory, and processing circuitry. The holder movably holds a plurality of reaction vessels. The first dispenser dispenses an analyte into each of the reaction vessels. The second dispenser dispenses a reagent into the reaction vessel. The detector detects light transmitted through the reaction vessel. The memory stores a test order. The processing circuitry controls the holder, the first dispenser, and the second dispenser based on the test order. The processing circuitry determines one of the reaction vessels to be used for measuring the analyte based on the test order, and performs control to collect characteristic data from another of the reaction vessels not used for measuring the analyte while the analyte is measured.
