Referring to fig. 1 to 3, a first embodiment of the present invention provides a blending tank, which includes a tank body 110, a waste discharge pipe 120, a liquid outlet pipe 130 and a liquid inlet unit, in which the liquid inlet unit is a first liquid inlet pipe 140, and the number of the first liquid inlet pipes 140 may be two.
The tank body 110 may be made of a metal material with good corrosion resistance and thermal conductivity, the tank body 110 needs to be soaked in the soaking solution 112 for maintenance when not in use, and the soaking solution 112 may be a diluent, such as sodium chloride.
The waste discharge pipe 120 is disposed at the bottom end of the tank body 110, and is used for discharging waste liquid in the tank body 110.
The liquid outlet pipe 130 is disposed at the bottom of the cell body 110, and is used for discharging the liquid in the cell body 110 for subsequent detection.
When the tank body 110 is vertically placed, the horizontal position of the waste discharge pipe 120 is lower than that of the liquid outlet pipe 130 so as to facilitate the discharge of waste liquid.
The first liquid inlet pipe 140 is communicated with the cell body 110, and is used for inputting a reagent to the cell body 110, such as an antibody reagent and a hemolysis reagent to the cell body 110.
The specific position of the first liquid inlet pipe 140 assembled on the tank body 110 may be determined according to the liquid level of the soaking solution 112 required to be installed in the tank bodies 110 of different specifications, and the bottom end of the first liquid inlet pipe 140 should be higher than the liquid level of the soaking solution 112 in the tank body 110, thereby preventing the soaking solution 112 from polluting the reagents in the first liquid inlet pipe 140. In the prior art, the reagent in the first liquid inlet pipe 140 is pumped back to form a section of gas column to achieve the isolation effect so as to prevent the soaking solution 112 from polluting the reagent in the first liquid inlet pipe 140, however, after the gas column is formed in the first liquid inlet pipe 140, the gas column is firstly discharged into the tank body 110 when the reagent is added into the tank body 110, and the operation can cause the accumulation of bubbles in the tank body 110, thereby affecting the detection result. When the bottom end of the first liquid inlet pipe 140 is higher than the soak solution, the effect of preventing the soak solution from polluting the reagent can be achieved without adopting a gas extraction column, and the problem of bubble accumulation in the tank body 110 is further avoided.
The first liquid inlet pipe 140 is disposed in a downward inclined manner relative to the axis of the tank 110, so that when the tank 110 contains a predetermined volume of liquid, an intersection point of an extension line of the first liquid inlet pipe 140 and the tank wall of the tank 110 is lower than the liquid level of the predetermined volume of liquid, specifically, an included angle of the first liquid inlet pipe 140 relative to the axis of the tank 110 may be 30 ± 15 degrees, and the arrangement may enable the reagent to enter the tank 110 in a splash-reducing manner. According to experimental verification, the reagent directly enters the liquid level in the tank body 110 and is directly sprayed on the inner wall of the tank body 110, so that liquid splashing can be reduced, and the generation of bubbles can be reduced. Although the reagent is thrown onto the inner wall of the tank body 110 to generate more wall-hanging splash liquid drops when the reagent is added at the beginning, the liquid level of the reagent gradually rises along with the gradual throwing of the reagent and submerges the wall-hanging splash liquid drops, and through the quantitative setting of the preset volume, the last part of thrown reagent can be directly thrown onto the liquid level instead of the inner wall, so that the generation of bubbles is reduced, the splashing of the liquid is reduced, the adding precision of the reagent is improved, and if the last part of thrown reagent is directly thrown onto the inner wall, the inner wall of the tank body 110 still has more wall-hanging splash liquid drops after the liquid throwing is stopped, thereby undoubtedly reducing the adding precision of the reagent, bringing about the difficulty of cleaning and simultaneously generating relatively more bubbles. The predetermined volume of liquid may be the sum of the volumes of the hemolysis reagent and the antibody reagent required for performing a specific protein assay, or the volume of the hemolysis reagent/antibody reagent required for performing a specific protein assay, depending on the amount of reagent added for each assay.

When the tank body 210 is vertically placed, the horizontal position of the waste discharge pipe 220 is lower than that of the liquid outlet pipe 230 so as to facilitate the discharge of waste liquid.
The second liquid inlet pipe 240 is disposed at the bottom of the cell body 210, and is used for inputting a reagent to the cell body 210, such as an antibody reagent and a hemolysis reagent to the cell body 210. The second liquid inlet pipe 240 and the liquid outlet pipe 230 may be flush with each other, the main pipe 242, the first branch pipe 243, and the second branch pipe 244 are respectively connected to three ports of the three-way valve 241, and the three-way valve 241 is communicated with the second liquid inlet pipe 240 by the main pipe 242.
