Embodiment Construction

[0109] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples, but the protection scope of the present invention is not limited thereto.

[0110] A fully automatic chemiluminescence immunoassay analyzer 9000, such as Figures 1 to 2 As shown, it includes a sample compartment 9300 , a reagent compartment 9400 , a cuvette storage compartment 9500 , an incubation compartment 9600 , a cleaning compartment 9700 and a detection compartment 9800 . When analyzing the composition of the sample to be tested, first put the sample and reagent into the sample compartment and the reagent compartment respectively, and the automatic chemiluminescence immunoassay analyzer takes out the reaction tube from the reaction tube storage compartment 9500 and puts it into the incubation compartment. Then add the sample and reagents into the reaction tube according to the predetermined procedure, start the incubation procedure, put the ...

Abstract

The invention relates to the technical field of sample analysis devices and in particular relates to a liquid heater for an analyzer. The liquid heater comprises a heating body, and at least one first liquid containing cavity and a second liquid containing cavity which are not communicated with each other in the heater, wherein at least one liquid containing cavity is stored in the other liquid containing cavity; the heating body is used for heating liquid in one liquid containing cavity; the heated liquid is used for heating liquid in the other liquid containing cavity. With the adoption of the liquid heater, the problem that the heating body is corroded by corrosive liquid is avoided through enabling the liquid in the at least one liquid containing cavity to be not in direct contact with the heating body and indirectly heating through heat conduction of the heated liquid, and the service life of the heating body is prolonged; moreover, the problem that the two heaters are used for independently heating respectively so that the mounting size is large and the cost is high are avoided, the size of the liquid heater is reduced and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sample analysis devices, in particular to a liquid heater for an analyzer. Background technique [0002] The automatic sample analysis device is used in the field of sample analysis technology such as biochemical analysis, immunoassay, fluorescent immunoassay, etc., to detect the content of substances in samples such as whole blood, plasma, serum or urine. In order to ensure accurate measurement results during detection, temperature control is required at each stage of the reaction to maintain a constant temperature reaction environment. For example, in the magnetic bead cleaning and separation stage, when the cleaning solution is used to clean the magnetic beads, if the temperature of the cleaning solution is low, it will cause damage to the constant temperature environment. Therefore, the cleaning solution needs to be heated before cleaning. In the reactant detection stage, it is also necessary to heat...
