[0027] In practical use, the user places the exosomes in a test tube, pushes the slider 3 to open it, places the test tube into the storage tube 4, pushes the lid 5, the slider 3 slides, and the lid 5 closes, achieving the purpose of individual sealed cryopreservation.
[0028] In this embodiment, a first support plate 6 is fixedly connected to one side of the inner surface of the outer shell 1, a power supply 7 is fixedly connected to one side of the upper surface of the first support plate 6, and a wire 8 is fixedly connected to one end of the power supply 7.
[0029] In actual use, by turning on the power supply 7, electrical energy is transmitted to the device through the wire 8, providing a stable and continuous power supply.
[0030] In this embodiment, an ultraviolet lamp 9 is fixedly connected to one side of the inner wall of the first support plate 6, and a protective shell is fixedly connected to one side of the inner wall of the first support plate 6. One end of the ultraviolet lamp 9 is fixedly connected to the wire 8.
[0031] In actual use, the wire 8 transmits electrical energy to the ultraviolet lamp 9, providing a stable and continuous power to the ultraviolet lamp 9, effectively killing bacteria and microorganisms on the outer surface of the storage compartment 2, and achieving full coverage disinfection by fixing it to both sides of the device.
[0032] In this embodiment, a cooling body 10 is fixedly connected to one side of the upper surface of the outer casing 1. The output end of the cooling body 10 passes through one side of the upper surface of the outer casing 1 and extends to one side of the inner wall of the cooling body 10. A condenser 11 is fixedly connected to the output end of the cooling body 10. The cooling body 10 includes an evaporator and a compressor.
[0033] In practical use, heat is absorbed through the circulation of refrigerant inside the cooling body 10. When the gaseous refrigerant flows through the evaporator, the evaporator absorbs heat from the surrounding environment, causing the refrigerant to evaporate into gas. After the condenser 11 receives the high-pressure refrigerant gas from the cooling body 10, it helps the refrigerant release heat inside the condenser 11 and turn into a liquid state, thus achieving the cooling effect.
[0034] In this embodiment, a condenser tube 12 is fixedly installed on one side of the outer surface of the condenser 11, and an aluminum fin 13 is fixedly connected to one end of the condenser tube 12.

[0038] In this embodiment, a display 16 is fixedly connected to one side of the outer surface of the housing 1.
[0039] In practical use, the display 16 is responsible for showing the cell's status, as well as the cooling temperature and time, so that the user can monitor and operate it.
[0040] Working principle: In use, the user places the exosomes in the test tube, pushes the slider 3 to open it, places the test tube into the storage tube 4, and pushes the lid 5, causing the slider 3 to slide and close the lid 5, achieving individual sealed cryopreservation. The power supply 7 is activated, and the wire 8 transmits electrical energy to the device, providing a stable and continuous power supply. The wire 8 also transmits electrical energy to the ultraviolet lamp 9, providing a stable and continuous power supply to the ultraviolet lamp 9, effectively killing bacteria and microorganisms on the outer surface of the storage chamber 2. By fixing it to both sides of the device, comprehensive disinfection is achieved. Heat is absorbed through the circulation of the internal refrigerant in the cooling body 10. When the gaseous refrigerant flows through the evaporator, the evaporator absorbs heat from the surrounding environment, causing the refrigerant to evaporate into a gas. After receiving the high-pressure refrigerant gas from the cooling body 10, the condenser 11 releases heat inside the condenser 11 and transforms the refrigerant into a liquid state, achieving a cooling effect. The condenser tube 12 is connected to the condenser 11 and is used to guide the coolant or condensate. It is fixed to one end of the condenser tube 12 by aluminum fins 13, providing additional surface area to promote more efficient heat exchange. The display 16 is responsible for displaying the cell status, as well as the cooling temperature and time, so that the user can monitor and operate to complete the cell storage.
