Measurement and analysis method for coagulation analyzer, and coagulation analyzer

Abstract

The invention relates to a measurement and analysis method for a coagulation analyzer, and the coagulation analyzer. The measurement and analysis method comprises the steps of acquiring reaction data in a reaction solution, comparing differences to find the maximum difference value, determining a reaction point corresponding to the maximum difference value as the highest reaction point, setting an initial reaction difference value or an end reaction difference value according to the maximum difference value, forward or backward searching points matching with the initial reaction difference value or the end reaction difference value according to the highest reaction point, determining a corresponding reaction point as an initial reaction point or an end reaction point; and performing subsequent analysis according to the initial reaction point and the end reaction point. The measurement and analysis method for the coagulation analyzer and the coagulation analyzer determine the initial reaction difference value or the end reaction difference value according to the highest reaction point, finds the initial reaction point and the end reaction point corresponding to the initial reaction difference value or the end reaction difference value respectively by forward or backward searching according to reaction time, thereby reducing influences on sample reaction violence degree of external environment, so that stability and accuracy of the measurement are increased and reproducibility of the sample analysis is relatively good.

Description

technical field [0001] The invention relates to a medical device, in particular to a coagulation analyzer and a measurement and analysis method for the coagulation analyzer. Background technique [0002] At present, most of the analysis and measurement methods of semi-automatic coagulation analyzers used in hospitals are nephelometry, which determines the detection end point according to the change of scattered light of the sample to be tested during the coagulation process. In this method, the monochromatic light source of the detection channel is at a 90-degree right angle to the photodetector. When a coagulation activator is added to the sample, the scattered light intensity of the sample gradually increases with the formation of the fibrin clot in the sample. When the sample is completely solidified, the intensity of the scattered light does not change. Usually, the starting point of solidification is regarded as 0%, the end point of solidification is regarded as 100%, a...

AI Technical Summary

Problems solved by technology

The intensity of the reaction of different samples is not the same, and the repeated measurement process of the same sample is different due to differences in cups and measurement methods, resulting in poor accuracy and poor repeatability

[0005] And the test process may be affected by the outside world, such as table vibration, etc. When the impact is large, the instrument will mistakenly detect it as the starting point or end point of the reaction, resulting in abnormal values ​​in normal measurement results, or normal values ​​in abnormal results
