[0002] In the daily operation of clinical laboratories, reagent addition is one of the routine experimental operations.

[0003] The conventional method of adding reagents is to pour the reagents from the storage bottle into the reagent tank, and then use pipettes and other pipetting tools to transfer and add reagents. With the advancement of automation in the production process, equipment that can achieve batch addition has greatly improved production efficiency. However, the volume of conventional reagent tanks is difficult to store all the sample addition reagents at one time, and they need to be replenished during the experiment. Therefore, the conventional treatment method is to replenish the missing reagents through manual observation, but manual operation of replenishing reagents multiple times is time-consuming and labor-intensive, and there are errors in the volume of added liquid after manual visual inspection, which will affect the continuity of the experiment. In scenarios where multiple reagents are used at the same time, experimenters are also prone to operational errors such as adding the wrong reagents, which can easily lead to quality risks. Summary of the invention

[0028] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0029] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0030] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0032] The following is combined with Figures 1 to 8 The embodiments of the present invention are further described.

[0033] The present embodiment proposes the following technical scheme: a reagent tank 1 for batch adding of samples, comprising a reagent tank 1 and a temporary storage tank 6, wherein a liquid adding tube 7 is fixedly penetrated and connected to the top of the temporary storage tank 6, an end cap 8 is externally threadedly connected to the liquid adding tube 7, the end cap 8 is connected to the sealed liquid adding tube 7, and a bracket is fixedly connected to the bottom of the temporary storage tank 6, the temporary storage tank 6 is a square or cylindrical structure, and in the present embodiment, the temporary storage tank 6 is a square structure.

[0034] Among them, a first delivery pipe 15 and a second delivery pipe 16 are fixedly connected at the bottom side of the temporary storage tank 6, and the inner cavities of the first delivery pipe 15 and the second delivery pipe are both square cavities 17. A first baffle 18 is rotatably connected in the first delivery pipe 15, and a second baffle 20 is rotatably connected in the second delivery pipe 16. A first block 19 is fixedly connected to the position of the first baffle 18 corresponding to the first delivery pipe 15, and a second block 21 is fixedly connected to the position of the second baffle 20 corresponding to the second delivery pipe 16. Therefore, through the obstruction of the first block 19 and the second block 21, the first baffle 18 and the second baffle 20 can only be opened by one-way rotation, the discharge pipe 3 can only add liquid to the reagent tank 1, and the air inlet pipe 4 can only take air into the temporary storage tank 6.

[0035] In a further design, a valve assembly is connected to the outside of the first delivery pipe 15 and the second delivery pipe 16 , and a drain pipe 3 and an air inlet pipe 4 are connected to the outside of the valve assembly. One end of the drain pipe 3 and the air inlet pipe 4 extend into the reagent tank 1 .

[0036] Specifically: the valve assembly includes a support plate 5 and a rotating plate 9 rotatably connected to the support plate 5, and two channels 10 are provided in the rotating plate 9;

[0037] Among them, a shift plate 11 is fixedly connected to the top of the turntable 9, and a cross plate is fixedly connected to the outside of the shift plate 11. A positioning rod 14 is slidably connected through the middle of the cross plate. The positioning rod 14 is used to be plugged into the first positioning hole 12 and the second positioning hole 13, and a first positioning hole 12 and a second positioning hole 13 are opened on the top of the support plate 5. When the positioning rod 14 is plugged into the first positioning hole 12, the channel 10 corresponds to the drain pipe 3 and the air intake pipe 4. When the positioning rod 14 is plugged into the second positioning hole 13, the channel 10 is staggered with the drain pipe 3 and the air intake pipe 4.

[0038] In a further design, a pull ring 23 is fixedly connected to the top of the positioning rod 14, and a spring 22 is sleeved on the outside of the positioning rod 14. The two ends of the spring 22 are respectively connected to the pull ring 23 and the cross plate. Therefore, the setting of the pull ring 23 makes it convenient to pull the positioning rod 14, and the diameter of the support plate 5 is five to ten centimeters, preferably ten centimeters; the diameter of the turntable 9 is six to nine centimeters, preferably eight centimeters.

[0039] In further refinement, a scale line 2 is provided in the reagent tank 1, the bottom of the air inlet pipe 4 is flush with the scale line 2, one end of the discharge pipe 3 extends to below the scale, and another end of the discharge pipe 3 extends to three to five centimeters below the scale line, preferably three centimeters, and the diameters of the air inlet pipe 4 and the discharge pipe 3 are one to five centimeters, preferably three centimeters; the above technical scheme is explained as follows: when there is no reagent below the scale line 2 in the reagent tank 1, since the discharge pipe 3, the air inlet pipe 4 and the temporary storage tank 6 are closed spaces, the air enters the temporary storage tank 6 from the air inlet pipe 4 under the influence of atmospheric pressure. When the reagent height level in the reagent tank 1 reaches the scale line 2, the air inlet pipe 4 is covered by the reagent, and the air cannot enter the temporary storage tank 6 due to the air pressure, and the drainage is completed.

[0040] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:

[0041] When in use, first rotate the turntable 9, so that the positioning rod 14 on the turntable 9 is inserted into the second positioning hole 13, so that the channel 10 is staggered with the discharge pipe 3 and the air inlet pipe 4. Figure 5 And attached Figure 6 As shown in;

[0042] Keep the drain pipe 3 and the air inlet pipe 4 closed, then open the end cover 8, add the required reagent to the temporary storage tank 6 through the liquid adding pipe 7, and after the addition is completed, close the end cover 8 and ensure that the liquid adding pipe 7 is airtight;

[0043] Then, the positioning rod 14 is pulled out, and the rotating disk 9 is rotated to make the positioning rod 14 plug into the first positioning hole 12, so that the channel 10 is connected with the discharge pipe 3 and the air inlet pipe 4. Due to gravity, the reagent in the temporary storage tank 6 flows into the reagent tank 1 through the discharge pipe 3. Due to the obstruction of the second stopper 21 outside the second baffle 20, the second baffle 20 cannot be rotated backward to open, so the reagent will not flow out from the air inlet pipe 4;

[0044] Since the drainage pipe 3, the air inlet pipe 4 and the temporary storage tank 6 are closed spaces, the air enters the temporary storage tank 6 through the air inlet pipe 4 under the influence of atmospheric pressure. When the reagent level in the reagent tank 1 reaches the scale line 2, the air inlet pipe 4 is covered by the reagent, and the air cannot enter the temporary storage tank 6 due to the air pressure, and the drainage is completed.

[0045] When the reagent in the reagent tank 1 is used, the reagent height decreases. After it is lower than the reagent scale line 2, it is affected by the atmospheric pressure. The air enters the temporary storage tank 6 through the air inlet pipe 4. The reagent in the temporary storage tank 6 flows into the reagent tank 1 through the discharge pipe 3. When the reagent height level reaches the reagent scale line 2, the air inlet pipe 4 is covered by the reagent. Due to the air pressure, the air cannot enter the temporary storage tank 6, and the discharge is completed. Therefore, the reagent in the reagent tank 1 can be kept at a stable height.

[0046] Therefore, in this embodiment, there is no need for multiple manual operations to add reagents, and the reagents in the reagent tank can be kept at a stable height state, avoiding experimental failure due to insufficient reagents, improving the continuity of the experiment, and reducing quality risks.

[0047] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
