Description

Technical Field

[0001] The utility model relates to single molecule detection, in particular to a reagent self-mixing device. Background Art

[0002] The single-molecule fluorescence immunoassay analyzer uses immunodiagnostic technology to detect neural markers, myocardial markers, inflammatory markers, tumor markers, infection markers, etc. It detects single molecules through capillary flow technology to achieve sample trace concentration detection. The instrument mainly includes a reagent module, an incubation module, a magnetic separation module, a sample addition module, etc. The reagent module is a device for storing reagents in the single-molecule fluorescence immunoassay analyzer. In order to obtain uniform reagents, the reagents stored in the reagent module need to be kept in a mixed state so that the reaction reagents added in the subsequent reaction are uniform. Therefore, a device that can mix multiple reagent bottles at the same time is required in the reagent module.

[0003] Reagent bottle mixing devices are often used in medical testing equipment, such as chemiluminescence equipment. Domestic and foreign manufacturers mostly use separate stirring to mix reagents in order to solve the problem of reagent bottle mixing in the instrument. This often leads to two problems:

[0004] 1. When different reagents are mixed by separate stirring, there is a risk of cross contamination of different reagents.

[0005] 2. A stirring needle assembly is separately provided in the whole machine, which occupies a large amount of space and is expensive, greatly increasing the cost of the whole machine. Summary of the invention

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. Self-mixing is achieved;

[0014] By using a fixed main gear and a driven gear meshing with the main gear arranged on the lower side of the turntable, when the turntable rotates, the driven gear revolves and rotates around the main gear, thereby driving the reagent bottle to revolve and rotate around the main gear, thereby achieving self-mixing of the reagent, without the need for a stirring needle, and avoiding the cross contamination problem existing in the prior art;

[0015] 2. Good mixing effect;

[0016] The inner wall of the reagent bottle is provided with an inward protrusion extending in the up-down direction, so that the reagent is fully mixed during the rotation of the reagent bottle and bubbles are avoided during the mixing process;
