[0002] Cell preservation fluid is a liquid used to maintain the physiological state of cells and keep them viable. It is usually composed of a series of components, including buffers, nutrients, adjuvants and antioxidants, etc., which need to be proportioned when used.

[0003] For example, a cell preservation solution proportioning device with the authorization announcement number "CN220159880U" can select and use different quantitative boxes according to the proportion of the proportion when proportioning the preservation solution, thereby conveniently improving the accuracy of the preservation solution proportioning. However, the U-shaped frame of the cell preservation solution proportioning device can only accommodate liquid preparation containers of fixed sizes, and the same type of liquid preparation containers need to fit the inner wall of the U-shaped frame to be placed in the U-shaped frame, thereby increasing work limitations. At the same time, when moving the liquid preparation container, the cell preservation solution proportioning device requires workers to manually push the U-shaped frame to move the position of the preparation container. Workers are required to frequently move the U-shaped frame during work, thereby increasing the labor force of workers. Utility Model Content

[0027] Working principle:

[0028] When the cell preservation solution needs to be mixed, the worker first places the mixing container between the two vertical plates 206 (the mixing container is the prior art disclosed in the authorization announcement number "CN220159880U", such as Figure 7 ), after the liquid preparation container is placed, the external power supply of the cylinder 202 is connected and started, the cylinder 202 drives the cross block 203 to move downward, the cross block 203 drives the two rod bodies 204 to move downward through the pin shaft, the outer sides of the rod bodies 204 drive the vertical plates 205 to move relative to each other through the slide grooves, and then drive the vertical plates 206 to move relative to each other, the outer walls of the two vertical plates 206 contact the liquid preparation container to fix it, and after the liquid preparation container is fixed, the cylinder 202 is closed, according to the above method, the cylinder 202 drives the cross block 203 to move in the opposite direction to reset the two vertical plates 206, and the position of the liquid preparation container is fixed in the above method;

[0029] The external power supply of the motor 301 is turned on and started, the motor 301 drives the connecting rod 302 to rotate, the connecting rod 302 drives the vertical rod 303 to move to the right through the slide groove, and the vertical rod 303 drives the gear 304 to move. Since the lower end of the gear 304 is meshed with the first rack 305, the gear 304 rotates together when the gear 304 moves, and the gear 304 can drive the second rack 306 to move a distance twice longer than the first rack 304. The second rack 306 drives the block 9 to move and then drives the fixed liquid preparation container to move to the right. When the liquid preparation container is under the other cylinder 7, the motor 301 is turned off. According to the above method, the motor 301 can be reversed to reset the liquid preparation container. The liquid preparation container can be driven by the above method to move to the bottom of different cylinders 7 according to different liquids to transport liquids (the cell preservation liquids stored in the two tanks 4 are different);

[0030] Then, the discharge port 6 is opened by the electromagnetic valve, and then the cell preservation solution pre-stored in the tank body 4 is introduced into the cylinder body 7. The amount of the cell preservation solution introduced into the cylinder body 7 is controlled according to the scale lines on the surface of the cylinder body 7. When the cell preservation solution in the cylinder body 7 reaches the required amount, the discharge port 6 is closed by the electromagnetic valve. The cell preservation solution is quantified in the above manner.

[0031] Then, turn the valve under the cylinder 7, and the quantified cell preservation fluid in the cylinder 7 will be introduced into the liquid preparation container for collection. After the cell preservation fluid in the cylinder 7 is introduced into the liquid preparation container, the fixation of the liquid preparation container is cancelled according to the above method and it can be taken out manually.
