Specimen Processing Display for Cross-Lot Accuracy Trends
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing specimen analyzers fail to account for variations in the concentration of measurement target substances across different production lots of accuracy control samples, making it difficult to anticipate the tendencies of accuracy control values for future analyses.
Innovation Solution
A specimen processing system that includes an analysis unit, an accuracy control information storage unit, and a display control unit to simultaneously display accuracy control data of samples with different production lot numbers, allowing for direct comparison and visualization of trends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If accuracy control data from multiple production lots are displayed separately, then data clarity is maintained, but the ability to compare trends across lots is reduced
Solution Approach 1:
The patent merges accuracy control data from multiple production lots into a single display view, showing both current lot data and reference lot data simultaneously. This allows operators to compare trends across different production lots while maintaining the precision of individual lot measurements, directly resolving the contradiction between data clarity and comparison capability.
2Device complexity
If only current production lot data is displayed, then data simplicity is maintained, but the ability to predict future accuracy control tendencies is reduced
Solution Approach 1:
The patent implements preliminary action by displaying reference accuracy control data from previous production lots alongside current lot data. This allows operators to identify trends and patterns before switching production lots, enabling them to predict and prepare for future accuracy control tendencies rather than reacting to problems after they occur.
3Ease of operation
If accuracy control data is displayed without production lot differentiation, then ease of operation is improved, but data accuracy and traceability are reduced
Solution Approach 1:
The patent applies local quality by differentiating the display presentation for different production lots while maintaining a unified display interface. Current production lot data is highlighted or distinguished from reference lot data through visual cues, allowing operators to easily distinguish data sources without complicating the overall display operation, thus maintaining both ease of operation and production lot traceability.
Data Source
AI summary
In a specimen processing system, plural pieces of accuracy control data that is time series data of an accuracy control value obtained by analyzing an accuracy control sample by an analysis unit is stored in an accuracy control measurement information database. Then, the display control unit simultaneously displays the accuracy control data of plural accuracy control samples of the same type and different production lot numbers on a touch display based on the accuracy control data stored in the accuracy control measurement information database.
