Problems solved by technology
[0004] However, this reagent mixing device can only mix one reagent bottle at a time, so its mixing cycle is long and the efficiency is low; moreover, since the DC motor is located directly below the reagent chamber containing the reagent bottle, it is extremely prone to condensation due to condensation. water failure

Embodiment Construction
[0028] Below, specific implementations of the reagent mixing device according to the present invention will be described with reference to the accompanying drawings.
[0029] figure 2 A schematic perspective view showing a reagent mixing device according to an exemplary embodiment of the present invention; image 3 shows a top view of a reagent mixing device according to an exemplary embodiment of the present invention; Figure 4 shows along the image 3 Line A-A of , cross-sectional view of the reagent mixing device.
[0030] refer to figure 2 , the reagent mixing device 100 according to the present invention includes a reagent disk 1 , at least one first rotating part 2 and a second rotating part 3 . The reagent disc 1 can be driven around its central axis (i.e. the first axis I-I', such as Figure 4 shown) to rotate, and is configured to drive the reagent bottle to rotate together. For example, the reagent disc 1 may be fixedly connected to a central shaft 9 driven ...

The invention relates to a reagent blending device and an analysis meter. The reagent blending device comprises a reagent disc, at least one first rotary component and a second rotary component, wherein the reagent disc can rotate around a first axis, the first rotary components can bear a reagent bottle and are attached to the reagent disc in the mode of being capable of rotating around a second axis, and each first rotary component is provided with a first transmission part; the second rotary component can rotate around the first axis and is provided with a second transmission part, the second transmission part of the second rotary component is matched with the first transmission part of each first rotary component so that when the second rotary component moves up and down along the first axis, the first rotary components rotate around the second axis, the second rotary component and the reagent disc can rotate together around the first axis, and the second rotary component can reciprocate up and down along the first axis while rotating together with the reagent disc so as to drive the first rotary components to rotate around the second axis. By the adoption of the reagent blending device, reagent blending effect can be improved, and reagent blending efficiency can be improved.
Description
technical field [0001] The invention relates to a reagent mixing device, in particular to a reagent mixing device used in the field of chemiluminescence immunoassay. Background technique [0002] When performing chemiluminescent immunoassay, the reagents added to the cuvette need to fully react with the sample to be tested, so the reagents must be uniformly dispersed and suspended in the buffer. The mixing effect of the reagent will directly affect the final test result, so the reagent mixing device used to mix the reagent plays a vital role in the entire reaction process. [0003] The reagent mixing device in the prior art usually adopts a double DC motor mixing method, that is, the reagent mixing device generally has two DC motors. figure 1 A schematic view of a prior art reagent mixing device 1000 is shown. like figure 1 As shown, the reagent mixing device 1000 includes a DC gear motor 101 for driving the clutch 103 to rotate, and a motor 102 for driving the DC gear mo...
