Embodiment Construction

[0060] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. Wherein, similar elements in different implementations adopt associated similar element numbers. In the following implementation manners, many details are described for better understanding of the present application. However, those skilled in the art can readily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the application are not shown or described in the description, this is to avoid the core part of the application from being overwhelmed by too many descriptions, and for those skilled in the art, it is necessary to describe these operations in detail Correlation operations are not necessary, and they can be completely de-correlated according to the description in the specification and general tec...

Abstract

The invention relates to a sample analyzer and a sample analysis method, the sample analyzer comprises a substrate separate injection structure, a determination mechanism, an ultrasonic device and a controller, the substrate separate injection structure is used for injecting a substrate into a reaction liquid in a containing cup, the determination mechanism is used for determining the reaction liquid, and the ultrasonic device is used for generating ultrasonic vibration to form ultrasonic waves; and the controller is used for controlling the ultrasonic device to emit ultrasonic waves into the reaction liquid of the injected substrate in the accommodating cup. The sample analyzer is provided with the ultrasonic device, the ultrasonic device is used for transmitting the ultrasonic waves into the reaction liquid, in which the substrate is injected, in the accommodating cup, and the ultrasonic waves can uniformly disperse agglomerated substances in the reaction liquid, so that the substrate can fully mark a reaction compound in the reaction liquid, missing marking is avoided, and the detection accuracy can be further improved.

Description

technical field [0001] The invention relates to in vitro detection equipment, in particular to a sample analyzer and a sample analysis method. Background technique [0002] Immunoanalyzer is a kind of analytical instrument with high sensitivity and high specificity. In clinical laboratory, it is often used to detect various analytical indicators of blood, urine or other body fluids. Traditional immune analyzers have a variety of working principles, including chemiluminescence, electrochemiluminescence and so on. Taking the heterogeneous chemiluminescent immunoassay analyzer as an example, its main working principle is: when it is necessary to measure a certain component in the sample, the corresponding antibody / antigen can be coated on the magnetic beads to form a magnetic bead reagent, and the specific marker The label forms a labeling reagent on the antibody. During the test, the sample to be tested is mixed with magnetic bead reagents, labeling reagents and other reagen...
