[0031] The clamping member 10 is a combination of a spring and a clamping block in the prior art, and the elastic force of the spring is used to ensure the fixation and stability of the urea reagent tube 6. When the urea reagent tube 6 is placed in the clamping block, the spring will apply a certain pressure to make the clamping block close to the urea reagent tube 6, thereby ensuring that the urea reagent tube 6 will not loosen or fall off. This structure can adapt to test tubes of different sizes and improve the user's operating convenience.
[0032] With the help of the above technical scheme, the reagent kit body 1 of the utility model integrates the urea reagent tube 6, the clamping member 10 and other components, so that the structure inside the entire reagent kit is compact and easy to carry and use. Through the cooperation of the built-in mounting plate 8, the column 7 and the fixing component 11, the urea reagent tube 6 can be conveniently fixed in the reagent kit to prevent the urea reagent tube from rolling or shifting, thereby improving the operational stability. Under the action of the handle 14, the built-in mounting plate 8 can be taken out from the inside of the reagent kit body 1, thereby facilitating the removal of the urea reagent tube 6 in the built-in mounting plate 8.
[0033] In one embodiment, for the above-mentioned column 7, a plurality of limiting holes 701 cooperating with the fixing component 11 are evenly opened on one side of the column 7, and the inside of the limiting hole 701 is provided with a rounded corner, so that under the action of the limiting hole 701, it can cooperate with the fixing component 11 and ensure stable cooperation with the fixing component 11.
[0034] In one embodiment, for the above-mentioned fixing component 11, the fixing component 11 includes a mounting groove 1101 arranged on one side of the top of the built-in mounting plate 8, a mounting hole 1102 is opened on one side of the mounting groove 1101, a limiting rod 1103 matching with the limiting hole 701 is inserted inside the mounting hole 1102, a sliding block 1104 is arranged at the end of the limiting rod 1103 away from the limiting hole 701, a toggle plate 1105 is arranged at the top of the sliding block 1104, a compression spring 1108 matching with the mounting groove 1101 is arranged at the end of the sliding block 1104 away from the limiting rod 1103, a limiting side strip 1106 matching with the sliding block 1104 is arranged inside the mounting groove 1101, and semicircular grooves 1107 are opened on both sides of the top of the toggle plate 1105, so that under the action of the fixing component 11, the urea reagent tube 6 can be conveniently fixed in the reagent box to prevent the urea reagent tube from rolling or shifting, thereby improving the operational stability.
[0035] The working principle of the fixing component 11 is as follows: first, place your hand inside the semicircular groove 1107 and slide it in the horizontal direction with force, thereby driving the toggle plate 1105 to move and driving the sliding block 1104 to slide, so that under the limiting action of the limiting side strip 1106, the limiting rod 1103 is separated from the limiting hole 701, so that the position of the built-in mounting plate 8 can be adjusted using the handle 14.
[0036] The reagents in the urea reagent tubes 6 include standard components and optional components, wherein reagent 1 and reagent 2 are standard components, and calibrators and quality control products are optional components, that is, reagent 1, reagent 2, calibrators and quality control products are packaged in sequence in the urea reagent tubes 6. Specifically:
[0037] 1) Reagent 1 is composed of tris(hydroxymethyl)aminomethane (Tris), urease, glutamate dehydrogenase (GLDH), adenosine diphosphate, and α-ketoglutarate.
[0038] 2) Reagent 2 consists of reduced coenzyme I (NADH).

[0045] The detection principle of the urea determination kit provided by the utility model is as follows: urea is hydrolyzed by urease to generate ammonia and carbon dioxide, ammonia is catalyzed by glutamate dehydrogenase (GLDH) in the presence of α-ketoglutarate and reduced coenzyme I (NADH) to generate glutamate, and NADH is oxidized to NAD at the same time. The rate of decrease of absorbance is monitored at a specific wavelength, which is proportional to the concentration of urea in the sample.
[0046] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

At the same time, according to the height of the test tube, the position of the built-in mounting plate 8 is adjusted by the handle 14, and the position of the built-in mounting plate 8 is adjusted under the cooperation of the fixing component 11 and the column 7 to adapt to the use of different types of urea reagent tubes 6. At the same time, when the fixing component 11 cooperates with the column, the entire built-in mounting base plate 4 can be taken out through the handle 14, thereby facilitating the taking of the urea reagent tube 6.
[0048] To sum up, with the help of the above-mentioned technical scheme of the utility model, the urea reagent tube 6, the clamping part 10 and other components are integrated inside the reagent kit body 1 of the utility model, so that the structure inside the entire reagent kit is compact and easy to carry and use. Through the cooperation of the built-in mounting plate 8, the column 7 and the fixing component 11, the urea reagent tube 6 can be conveniently fixed in the reagent kit to prevent the urea reagent tube from rolling or shifting, thereby improving the operational stability. Under the action of the handle 14, the built-in mounting plate 8 can be taken out from the inside of the reagent kit body 1, thereby facilitating the removal of the urea reagent tube 6 in the built-in mounting plate 8.
