Description

TECHNICAL FIELD

[0001] The utility model relates to the field of chemiluminescence immunoassay technology, especially to the reagent disc applied to the immunoassay instrument. BACKGROUND

[0002] Chemiluminescence immunoassay technology is a detection technology combining chemiluminescence substance and immunological reaction, mainly used for detecting trace antigen or antibody, and its principle is to use chemiluminescence substance to label antigen or antibody, the labeled antigen or antibody reacts with the corresponding antibody or antigen in the sample to form an antigen-antibody complex, and then the number of photons generated in the reaction is determined by a chemiluminescence analysis system to determine the concentration of the antibody or antigen in the sample, that is, a technology combining high-sensitivity light reaction and specific immunological reaction.

[0003] In chemiluminescence immunoassay technology, reagent suspension liquid containing magnetic microparticles is usually used, and the magnetic microparticle reagent suspension liquid is a mixed liquid containing small magnetic particles. The magnetic microparticles are usually nanoscale or micrometer-scale magnetic materials such as iron oxide, which can be used as a solid carrier with active groups such as carboxyl and amino groups on the surface. These groups can covalently bind antigens or antibodies, so the magnetic microparticle reagent suspension liquid plays a key role in chemiluminescence immunoassay technology.

[0004] However, the reagent suspension liquid containing magnetic microparticles will gradually sink under the action of gravity in a static state, resulting in the precipitation of magnetic microparticles in the suspension liquid, and the microparticles in the suspension liquid will be unevenly distributed, which will lead to unstable and inaccurate detection signals and affect the accuracy of subsequent detection results. In addition, the reagents used in chemiluminescence immunoassay contain biologically active components such as antigens, antibodies, and enzymes, which need to be refrigerated at 2-8℃. If the temperature is too high, it will change the chemical structure and cause the reagent to fail, affecting the accuracy of subsequent detection results.

[0005] Therefore, how to fully mix the reagent suspension liquid containing magnetic microparticles (used in chemiluminescence immunoassay) and at the same time provide good refrigeration to improve the accuracy of subsequent detection results has become a problem to be solved.

[0042] In the embodiment, the refrigeration module 16 is detachably installed at and penetrates the bottom of the reagent disc 3 and the reagent pot 23, the positions where the refrigeration module 16 contacts the reagent disc 3 and the reagent pot 23 can be provided with a heat preservation layer, the refrigeration end of the refrigeration module 16 faces upwards and is located in the reagent pot 23, and the heating end of the refrigeration module 16 faces downwards and is located outside the reagent disc 3.

The external bar code scanner is prior art known to those skilled in the art, and will not be described here.
