[0025] Example 1

[0026] In this embodiment, if Figure 1-Figure 5 As shown, a temperature-controllable cell storage bag includes an outer bag 101, the outer bag 101 is a heat-insulating material to prevent the rapid loss of liquid nitrogen temperature, a partition bag 102 is arranged inside the outer bag 101, a chamber 103 is arranged inside the partition bag 102, and the chamber 103 is a liquid nitrogen chamber. A plurality of placement grooves 105 for placing cell freezing bags 104 are opened on the surface of the partition bag 102. The placement grooves 105 are consistent with the size of the cell freezing bags 104. The placement grooves 105 can be set to different sizes and are suitable for storing multiple cell freezing bags 104 of different specifications at the same time. It also includes a low temperature mechanism 200 and The temperature regulating mechanism 300 and the low temperature mechanism 200 are arranged on one side of the outer bag 101 and are used to store the cell freezing bags 104 at low temperatures. The temperature regulating mechanism 300 is arranged on the side of the outer bag 101 away from the low temperature mechanism 200 and is used to adjust the internal temperature of the partition bag 102. Before the temperature-controlled cell storage bag is used, first check whether the storage bag can be used normally, then place a number of cell freezing bags 104 in the placement slot 105, operate the low temperature mechanism 200 through the display 107, and inject liquid nitrogen into the partition bag 102, so that the storage bag enters a state of being ready for use;

[0027] Among them Figure 2-Figure 4As shown, the low temperature mechanism 200 includes a fixedly installed box body 201, and the box body 201 plays a protective role for the liquid nitrogen storage tank 202. The box body 201 is provided with a liquid nitrogen storage tank 202 inside, and the liquid nitrogen storage tank 202 is used to store liquid nitrogen to avoid safety accidents. The liquid nitrogen storage tank 202 is connected to the partition bag 102 through a delivery pipe 203, and a pump is provided at one end of the delivery pipe 203 to facilitate the delivery of liquid nitrogen to the inside of the partition bag 102. Liquid nitrogen is filled into the chamber 103 through the delivery pipe 203 to ensure that the temperature in the partition bag 102 remains stable. A solenoid valve 204 is provided on the outside of the delivery pipe 203, and the solenoid valve 204 is electrically connected to the display 107. The delivery amount of liquid nitrogen is controlled by the solenoid valve 204;

[0028] Among them Figure 2-Figure 5 As shown, the temperature regulating mechanism 300 includes a plurality of openings 301 opened on the surface of the outer bag 101, and the openings 301 are in contact with the surface of the compartment bag 102, so that the cooling block 302 can maintain contact with the compartment bag 102, so that the temperature generated by the refrigeration plate 303 can be transmitted to the compartment bag 102, and the liquid nitrogen inside the compartment bag 102 can be quickly cooled and pre-cooled. The cooling block 302 is fixedly installed inside the opening 301, and a cooling plate 303 is arranged on one side of the cooling block 302. The cooling plate 303 is electrically connected to the display 107. By operating the display 107, the user can quickly perform the cooling operation. A radiator 304 is arranged on the side of the cooling plate 303 away from the cooling block 302, and the side of the cooling plate 303 is dissipated by the radiator 304. The radiator 304 is electrically connected to the display 107.

[0029] Among them Figure 1 As shown, both sides of the outer bag 101 are fixedly provided with hand straps 106, which facilitate the user to transport the storage bag, making it portable and increasing the practical effect of the storage bag;

[0030] Among them Figure 2 As shown, a display 107 is provided on one side of the box 201, and the user can observe the temperature inside the compartment bag 102 in real time through the display, so that the temperature adjustment mechanism 300 can be quickly operated to ensure the cell activity inside the cell freezing bag 104;

[0031] Among them Figure 1-Figure 3 As shown, a liquid outlet is provided on one side of the partition bag 102, and a liquid outlet pipe 108 is provided at the liquid outlet and extends to the outside of the outer bag 101. The function of the liquid outlet and the liquid outlet pipe 108 is to facilitate the discharge of liquid nitrogen inside the partition bag 102 when the storage bag is idle, so as to avoid affecting the next use;

[0032] Example 2

[0033] The difference from Example 1 is that Figure 4 As shown, a temperature sensor is provided inside the partition bag 102, and the temperature sensor is electrically connected to the display 107. The temperature sensor monitors the temperature of the liquid nitrogen in the partition bag 102 and transmits the temperature data to the display 107 for display, so that the user can observe the temperature in the partition bag 102 and operate it conveniently;

[0034] Among them Figure 2 and Figure 3 As shown, a box door 205 is provided on one side of the box body 201 close to the liquid outlet pipe 108, and the box door 205 is connected to the box body 201 through a hinge, which facilitates the replacement and maintenance of the liquid nitrogen storage tank 202 and reduces the possibility of safety accidents.

[0035] During use, the user manually operates the display 107 to open the pump and the solenoid valve 204, thereby transporting the liquid nitrogen in the liquid nitrogen storage tank 202 to the chamber 103. The liquid nitrogen transmits the temperature to the surface of the cell freezing bag 104 through the partition bag 102, thereby playing a role in low-temperature preservation. When the temperature sensor inside the partition bag 102 detects that the temperature of the liquid nitrogen has risen, the refrigeration plate 303 and the radiator 304 are started, and the temperature of the liquid nitrogen inside the partition bag 102 is reduced through the cooling block 302, thereby achieving the purpose of temperature control. The operation is relatively simple and the practicability is good.

Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
