Sample Analyzer Stirring Mechanism for Quality Control Sample Homogeneity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Quality control samples stored in cooling units often result in insufficient stirring due to pseudo-ingredients and long-term storage at low temperatures, leading to non-uniform dispersion of blood cell components, which can cause false high values and improper measurement results if not adequately agitated before analysis.
Innovation Solution
A quality control sample measurement method that includes a distinct stirring operation mode for quality control samples, differing from the mode used for subject samples, ensuring thorough agitation by varying parameters such as stirring speed, angle, number of inversions, and impact application to ensure uniform dispersion of blood cell components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the quality control sample is stirred in the same manner as the subject sample, then the stirring process is simplified, but the quality control sample will not be sufficiently agitated due to the influence of pseudo-ingredients and the effect of long-term storage at low temperature
Solution Approach 1:
The patent applies local quality by implementing different stirring parameters specifically for quality control samples compared to subject samples. The stirring mechanism adjusts its operation based on the sample type, providing localized optimization for QC samples that have been stored at low temperatures and contain pseudo-ingredients, ensuring they receive the appropriate agitation intensity required for proper mixing.
Solution Approach 2:
The patent implements parameter changes by modifying stirring conditions (such as stirring speed, duration, or intensity) when processing quality control samples. The control unit detects the sample type and automatically adjusts the stirring parameters to ensure sufficient agitation for QC samples while maintaining appropriate conditions for subject samples, thereby resolving the contradiction between simplified process and reliable results.
2Stability of the object's composition
If the quality control sample is stored in the cooling unit for long-term storage, then the sample stability is improved, but the blood cell component may not be uniformly dispersed due to the effect of long-term storage at low temperature
Solution Approach 1:
The patent applies preliminary action by performing enhanced stirring on quality control samples before measurement. The system detects that a QC sample is being processed and automatically applies a preliminary stirring step with adjusted parameters to ensure uniform dispersion of blood cell components that may have settled during long-term cold storage, thereby preparing the sample properly for accurate measurement.
3Productivity
If the quality control sample is measured without proper stirring, then the measurement process is faster, but the measurement result of the quality control sample may not be obtained normally
Solution Approach 1:
The patent implements dynamics by making the stirring process adaptive and variable based on sample type. The control unit dynamically adjusts stirring parameters (speed, duration, intensity) according to the detected sample type, allowing the system to optimize the balance between processing speed and measurement accuracy for each sample category, particularly ensuring adequate stirring for QC samples while maintaining efficiency.

AI summary
A quality control sample measurement method, a sample analysis device and a supply device capable of normally acquiring a measurement result of a quality control sample are provided. The quality control sample measurement method for measuring a quality control sample stored in a cold state includes a step of stirring the quality control sample in a first operation mode (step S2) and a step of measuring the stirred quality control samples (step S3). The stirring in the first operation mode differs from the stirring in the second operation mode for stirring the subject sample collected from the subject.
