To obtain a sufficient number of NK cells, effective NK cell expansion technologies need to be developed. However, existing NK cell expansion kits may suffer from breakage due to shaking during transportation, resulting in a high breakage rate. Therefore, those skilled in the art have provided an NK cell expansion kit to address the problems mentioned in the background section. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The operator holds the handle and pushes upwards to lift the lid. The operator places the reagent bottle into the reagent holder. Upon insertion, the spring rod compresses the spring inwards, allowing the semi-circular rubber clamping plate to contact the reagent bottle. The spring returns, causing the spring rod to push the semi-circular rubber clamping plate to hold the reagent bottle. Rubber pads are installed between the semi-circular rubber clamping plate and the reagent bottle to effectively prevent damage from compression. The reagent dropper is used to add or draw reagents from the reagent bottle. When the rubber bulb of the dropper is squeezed, the air inside the dropper is expelled. Then, the dropper is inserted into the reagent bottle. Releasing the rubber bulb causes the reagent to be drawn into the dropper because the pressure inside the dropper is lower than the pressure inside the reagent bottle. When adding reagents to other containers or performing experimental operations, squeezing the rubber bulb allows the reagent to be drawn from the dropper. The reagent droppers are dispensed in the same quantity as the reagent bottles and are used one-to-one to avoid confusion. The second support is used to place the reagent dropper corresponding to the position of the reagent bottle. The elastic clamping structure, composed of clamping parts, springs, spring rods, and semi-circular clamping plates, can accommodate reagent bottles of different diameters. This allows the NK cell amplification kit to accommodate reagent bottles of various sizes, improving the kit's versatility. Under different experimental needs or reagent supply conditions, there is no need to replace the entire kit or reagent holder, saving costs and improving the kit's adaptability. The combination of reagent bottles and droppers makes the operation of aspirating and transferring reagents simple and precise. In NK cell amplification experiments, accurate reagent addition is crucial for cell growth and expansion. Attached Figure Description

[0021] The working principle of this utility model is as follows: When using this utility model, firstly, the operator holds the handle 3 and pushes upward to lift the lid 2. The operator then places the reagent bottle 10 into the reagent holder 5. Upon placement, the spring rod 8 is forced inward to compress the spring 7, allowing the semi-circular rubber clamping plate 9 to contact the reagent bottle 10. The spring 7 then rebounds, causing the spring rod 8 to push the semi-circular rubber clamping plate 9 to clamp the reagent bottle 10. Rubber pads are installed between the semi-circular rubber clamping plate 9 and the reagent bottle 10 to effectively prevent damage caused by squeezing the reagent bottle 10. The reagent dropper 12 is used to... Reagents are added or drawn into reagent bottle 10. When the rubber bulb of reagent dropper 12 is squeezed, the air inside the dropper is expelled. Then, the dropper is inserted into reagent bottle 10, and the rubber bulb is released. Because the pressure inside the dropper is lower than the pressure inside reagent bottle 10, the reagent is drawn into the dropper. When it is necessary to add reagents to other containers or perform experimental operations, the reagent can be dispensed from the dropper by squeezing the rubber bulb. The number of reagent droppers 12 is the same as that of reagent bottles 10, and they are used one-to-one to avoid confusion. The second support 11 is used to place the reagent droppers 12 corresponding to the positions of reagent bottles 10. Ultraviolet germicidal lamp. Tube 14 is installed on top of reagent storage box 1. Ceramic head 13 is used to fix the ultraviolet germicidal lamp tube 14. Turning the on / off knob of ultraviolet germicidal lamp tube 14 in function knob 26 starts ultraviolet germicidal lamp tube 14 and emits ultraviolet light. Ultraviolet light has a sterilizing and disinfecting effect, thereby killing microorganisms that may exist inside reagent storage box 1, reducing the risk of microbial contamination of NK cell amplification reagent, and ensuring the quality and safety of reagents. When it is necessary to lower the temperature inside reagent storage box 1, turn the on / off knob of circulation pump 17 in function knob 26 to circulate tube 18. The internal condensate circulation system includes ventilation holes 15 that allow adequate airflow to maintain the pressure balance within the reagent storage box 1 and help dissipate any odors or trace gases that may be generated. The ventilation sealing ring 24 of the sealing element 23 ensures that external contaminants do not enter during air exchange. The condensate feed pipe 16 is used to add new condensate. Pressing the pressure valve 22 in the control valve 21 discharges waste liquid from the condensate outlet pipe 20. The function display screen 25 displays the temperature and humidity values inside the reagent storage box 1, as well as various information such as whether the circulation pump is working and its operating status.
