Embodiment 1

[0033] Such as Figure 1 to Figure 3 As shown, a reagent prepackaged cuvette structure, which includes a first reagent chamber 3 with an opening at the top, a syringe 4 for storing the second reagent (ie, R2 reagent), an optical surface protection cover 1, a stirring device 5 and Cup lid2.

[0034] The structure of syringe 4 can be identical with prior art, can be made of sleeve 401, plunger 402, and liquid outlet 404 can be arranged on the bottom of sleeve 401, and one end of plunger 402 is inserted in the sleeve 401 and connects with sleeve 401. The inner wall of the sleeve is sealed, and the space enclosed by the plunger 402, the inner wall and the bottom of the sleeve 401 can store the R2 reagent. The other end of the plunger 402 is the pushing end 403, and the R2 reagent can be absorbed or extruded by pulling or pressing the pushing end 403.

[0035] The sleeve 401 of the syringe 4 is located in the first reagent chamber 3 and is in sealing connection with the first rea...

Embodiment 2

[0043] Such as Figure 4 As shown, the difference between this embodiment and the first embodiment lies in the structure of the stirring blade 502A of the stirring device. The stirring paddle 502A in this embodiment adopts a single paddle structure.

Embodiment 3

[0045] Such as Figure 5 As shown, the difference between this embodiment and the first embodiment lies in the structure of the stirring blade 502B of the stirring device. The stirring paddle 502B in this embodiment adopts a three-blade structure.

[0046] It can be seen from Examples 1 to 3 that the stirring paddle can also adopt a multi-blade structure.

Abstract

The invention relates to a reagent prepackaging cuvette structure which comprises a first reagent bin of which the top is provided with an opening, an injector for storing a second reagent, an optical surface protecting jacket and a cup cover, wherein the first reagent bin and an injector sleeve are respectively installed in the optical surface protecting jacket; the injector is positioned on the outer side of the first reagent bin; a liquid outlet of the injector is communicated with the inside of the first reagent bin through a pipeline; the cup cover is tightly connected with the outer side wall on the upper part of the optical protecting jacket; the inner side wall of the optical surface protecting jacket and the outer side wall of the first reagent bin are respectively tightly connected with the injector sleeve; the push end of an injector plunger is positioned in the cup cover, or penetrates out of the outer side wall of the optical protecting jacket; the side wall or bottom surface on the lower part of the first reagent bin is provided with an optical surface; and the optical surface protecting jacket is provided with an optical hole of which the position is corresponding to the optical surface. The structure has the characteristics of simplifying the operation process and professional skills of the user and enhancing the testing speed.

Description

technical field [0001] The invention relates to the field of inspection and analysis instruments, in particular to a cuvette structure. The present invention is a divisional application of the Chinese invention patent application with application number 201210047959.1. Background technique [0002] The existing conventional technical solutions at home and abroad usually place the reagents and cuvettes separately. The reason is that the reagents need to be refrigerated to ensure that they will not deteriorate. They are generally stored in special reagent bottles, and special reagent refrigeration chambers are designed. The cuvette can be a disposable plastic cup or a permanent glass cup. When working, use a special suction needle to suck out the refrigerated reagent, then spit it into the cuvette, react with the sample, and measure its content through the optical system to detect its change or Element. [0003] The deficiencies of the prior art are: [0004] 1. Separate re...
