[0027] Reference Figure 1-5 :

[0028] The utility model provides a tumor stem cell identification device, comprising a box body 1, wherein the box body 1 is provided with a plurality of bottle slots 2, a plurality of storage slots 3, a plurality of circular slots 5 and a plurality of test tube slots 6, and a storage slot 4 is provided in the middle of the box body 1, wherein reagent bottles 7 are placed in the plurality of bottle slots 2, adapters 8 are placed in the plurality of storage slots 3, culture dishes 10 are placed in the plurality of circular slots 5, test tubes 11 are placed in the plurality of test tube slots 6, a reagent extractor 9 is placed in the storage slot 4, and a control component for controlling the amount of reagent added is provided on the reagent extractor 9.

[0029] When in use, first take out the test tube 11 from the test tube slot 6, then inject the serum sample of the test object into the test tube 11, then centrifuge the serum sample in the test tube 11, then take out the supernatant and pour it into the culture dish 10, then take out the reagent bottle 7 in the bottle slot 2, inject the fluorescent dye reagent in the reagent bottle 7 into the culture dish 10, then slightly shake the culture dish 10, and then incubate it. After the incubation is completed, the tester uses a fluorescent microscope to observe the staining of the tumor stem cells inside the culture dish 10 to obtain the test results.

[0030] Among them, the adapter 8 includes a accommodating chamber 82, one end of the accommodating chamber 82 is fixed and connected with a connecting tube 83, and the other end of the accommodating chamber 82 is fixed and connected with a straw 81, the reagent extractor 9 includes a transparent tube 91, one end of the transparent tube 91 is fixed and connected with a conduit 92, and the conduit 92 can be inserted into the connecting tube 83, a rubber pad is glued to the outside of the conduit 92, a piston 93 is slidably connected in the transparent tube 91, and a piston rod 94 is fixed on one side of the piston 93, a partition 12 is fixed in the transparent tube 91, the piston rod 94 penetrates the partition 12 and is slidably connected to the partition 12, a pressing plate 13 is fixed to the end of the piston rod 94 away from the piston 93, a spring 14 is sleeved on the outside of the piston rod 94, and one end of the spring 14 is against the partition 12, and the other end of the spring 14 is against the pressing plate 13.

[0031] During use, when it is necessary to inject the fluorescent dye reagent in the reagent bottle 7 into the culture dish 10, first take out the reagent extractor 9 and the adapter 8, then insert the catheter 92 into the connecting tube 83, then press the pressing plate 13 to drive the piston rod 94 and the piston 93 to move, and then insert the straw 81 into the reagent bottle 7, and then release the pressing plate 13. At this time, the piston 93 is driven to move away from the adapter 8 under the rebound force of the spring 14, so that the fluorescent dye reagent in the reagent bottle 7 is sucked into the accommodating cavity 82, and then the straw 81 is pulled out of the reagent bottle 7, and then the adapter 8 and the reagent extractor 9 are moved to move the straw 81 to the culture dish 10. At the top, the pressing plate 13 is pressed to drive the piston rod 94 and the piston 93 to move, so that the piston 93 squeezes the air in the transparent tube 91 into the accommodating chamber 82, thereby discharging the fluorescent dye reagent in the accommodating chamber 82 into the culture dish 10. When the fluorescent dye reagent is extracted, the fluorescent dye reagent will not enter the reagent extractor 9, and the reagent extractor 9 will not be contaminated. Therefore, only the adapter 8 needs to be removed to replace the adapter 8, and the reagent extractor 9 can continue to be used. Moreover, the adapter 8 has a simple structure, is easy to manufacture and has a low manufacturing cost. Compared with the rubber-tipped dropper in the prior art, replacing the adapter 8 is more cost-effective than replacing the rubber-tipped dropper.

[0032] In addition, the control component includes a transparent sleeve 15 threadedly connected to the transparent tube 91 , a dosage line 16 is arranged on the outside of the transparent sleeve 15 , and the diameter of the pressing plate 13 is larger than the diameter of the transparent sleeve 15 .

[0033] During use, since there is a limit on the dosage when extracting the fluorescent dye reagent, when extracting the required dosage, the distance moved by the transparent sleeve 15 is controlled by rotating the transparent sleeve 15 and observing the dosage line 16. Since the distance from the pressing plate 13 to one end of the transparent tube 91 is constant in the normal state of the spring 14, this distance is recorded as A. By observing the dosage line 16, the distance from one end of the transparent sleeve 15 to one end of the transparent tube 91 can be known, and this distance is recorded as B. When the pressing plate 13 is pressed so that the pressing plate 13 and one side of the transparent sleeve 15 are against each other, the value is obtained by subtracting B from A. This value is the distance moved by the pressing plate 13, that is, the dosage of the fluorescent dye reagent absorbed. By changing the position of the transparent sleeve 15, that is, changing the value of B, the dosage of the fluorescent dye reagent is adjusted.

[0034] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
