Automatic Analyzer Parallel Calibration Accuracy Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic analyzing apparatuses require users to put patient measurements on standby until the results of the first accuracy management measurement and calibration measurement are confirmed, leading to inefficiencies and increased user burden, especially if analyte measurements are performed before calibration.
Innovation Solution
The apparatus performs calibration and accuracy management measurements in parallel, allowing for immediate analyte measurement and recomputation using a new calibration curve if accuracy is within acceptable ranges, thereby reducing user intervention and improving measurement efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the apparatus performs calibration measurement and accuracy management measurement sequentially, then the measurement precision is ensured, but the measurement time increases and productivity decreases
Solution Approach 1:
The apparatus performs the first accuracy management measurement before the calibration measurement to verify the calibration curve's accuracy in advance. This preliminary action allows the system to identify and correct calibration issues before they affect patient measurements, ensuring precision while enabling parallel processing of subsequent measurements.
Solution Approach 2:
The apparatus enables continuous measurement by performing accuracy management measurements and calibration measurements in parallel rather than sequentially. The system maintains continuous operation by overlapping these measurement processes, thereby improving productivity without compromising measurement precision.
2Measurement precision
If the apparatus requires manual selection and recheck of analyte before calibration, then the measurement precision is maintained, but the ease of operation decreases and user burden increases
Solution Approach 1:
The apparatus automatically identifies and selects analytes that require recomputation based on the calibration curve's accuracy status. The system self-manages the measurement process by automatically determining which analytes need to be rechecked and initiating the recomputation without requiring manual user selection, thereby improving ease of operation while maintaining measurement precision.
Solution Approach 2:
The apparatus uses feedback from the accuracy management measurement to automatically control the measurement process. When the calibration curve's accuracy is confirmed, the system automatically identifies analytes needing recomputation and executes the recheck process, eliminating the need for manual user intervention while ensuring measurement precision is maintained.
3Measurement precision
If the apparatus performs calibration measurement before analyte measurement, then the measurement precision is ensured, but the loss of time increases as patient measurements must wait
Solution Approach 1:
The apparatus performs the first accuracy management measurement before calibration to verify calibration curve accuracy in advance. This allows the system to proceed with analyte measurements more quickly once calibration is complete, as the accuracy has already been verified, thereby reducing the waiting time for patient measurements while ensuring precision.
Solution Approach 2:
The apparatus overlaps the accuracy management measurement and calibration measurement in time, allowing analyte measurements to be performed concurrently with these processes. This continuous operation eliminates sequential waiting and reduces the overall time loss for patient measurements while maintaining measurement precision.

AI summary
According to one embodiment, an automatic analyzing apparatus includes processing circuitry. The processing circuitry carries out a calibration measurement to prepare a calibration curve for a test item, and then carries out an accuracy management measurement to calculate an accuracy of the prepared calibration curve, determines whether or not the calculated accuracy is within an acceptable range, specifies, if the calculated accuracy is within the acceptable range, an analyte for which the test item needs to be recomputed, and recomputes the test item of the specified analyte using the prepared calibration curve.
