Sample Analyzer Timing Control for Urinary Sediment Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sample analysis, repeated measurements on the same sample over time can lead to unreliable results due to time differences between measurements, especially when there are delays in performing subsequent tests, which can result in bacterial growth and reduced reliability of urinary sediment measurement results.
Innovation Solution
A sample analyzer and analysis method that include a first measurement part for one measurement item and a second measurement part for another item, with a controller to output information when the time difference between these measurements exceeds a predetermined period, ensuring timely cross-checking and reliability evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple measurements are performed on the same sample over time, then comprehensive analysis coverage is improved, but measurement reliability deteriorates due to time differences and bacterial growth
Solution Approach 1:
The system performs preliminary actions by recording the measurement timing information and proactively notifying users before significant time differences occur. The notification system alerts users to perform subsequent measurements within the appropriate time window, preventing reliability degradation from bacterial growth.
Solution Approach 2:
The system implements feedback by continuously monitoring measurement timing and providing notifications when time differences exceed predetermined thresholds. This feedback loop enables users to adjust their measurement schedule to maintain sample integrity and measurement reliability.
2Ease of operation
If subsequent measurements are delayed, then operational flexibility is improved, but measurement accuracy deteriorates due to bacterial growth
Solution Approach 1:
The system establishes predetermined time periods in advance that define the window for acceptable measurement timing. By notifying users proactively when measurements are approaching this threshold, the system enables planned operations that maintain both flexibility and accuracy.
Solution Approach 2:
The notification system provides continuous feedback about measurement timing status, allowing users to make informed decisions about when to perform measurements. This feedback maintains measurement accuracy by alerting users to time constraints while preserving operational flexibility through timely notifications.
3Quantity of substance
If repeated measurements are performed without time monitoring, then measurement completeness is improved, but result reliability deteriorates due to undetected time delays
Solution Approach 1:
The system performs preliminary action by automatically recording measurement timing information and comparing it against predetermined time periods. This proactive timing monitoring ensures that completeness is achieved without compromising reliability through undetected delays.
Solution Approach 2:
The system implements feedback by notifying users when time differences between measurements exceed acceptable thresholds. This feedback mechanism ensures that both measurement completeness and result reliability are maintained by alerting users to timing issues that would otherwise go undetected.

AI summary
A sample analyzer includes: a first measurement part which performs measurement on a sample for a first measurement item; a second measurement part which performs a measurement on the sample for a second measurement item; an output section; and a controller configured to control the output section to output, when a time difference between a measurement on a sample performed by the first measurement part and a measurement on the sample performed by the second measurement part exceeds a predetermined time period, information based on an excess of the time difference.
