[0006] Preferably, the insertion port is located in the middle of the upper end of the base.

[0007] Preferably, the insertion port is a circular hole.

[0008] Preferably, the container is a cylindrical structure whose outer contour matches the insertion port, and the lower end of the container is a spherical structure.

[0009] Preferably, a gap is left between the outer wall of the container and the side wall of the insertion port.

[0010] Preferably, the base is made of transparent material.

[0011] Preferably, the cover plate is also provided with a cover sheet capable of closing the container opening.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The base and the container cooperate to form a space for freezing water to form ice cubes, and a groove for placing the container is provided in the middle of the upper end of the formed ice cubes, so that the ice cubes can well cover the container and improve the refrigeration performance of the biological tissues placed in the container;

[0014] 2. The biological tissue is stored and retrieved from the container opening on the cover, which is very convenient to use and the device can be reused;

[0015] 3. The amount of water in the base can be observed through the base made of transparent material, which is convenient for operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: Example

[0023] like Figure 1-Figure 4 As shown, a temporary low-temperature storage device for biological tissues comprises a base 1 and a cover plate 2. The base 1 is a hollow structure and an insertion port 3 is provided in the middle of the upper end of the base 1. The insertion port 3 is a circular hole. A container 4 for placing biological tissues is fixedly provided at the lower end of the cover plate 2. The container 4 extends into the inner cavity of the base 1 from the insertion port 3 and a space for freezing water to form ice cubes 6 is formed between the outer wall of the container 4 and the side wall of the inner cavity of the base 1. The container 4 is a cylindrical structure whose outer contour matches the insertion port 3. The lower end of the container 4 is a spherical structure, and a gap is left between the outer wall of the container 4 and the side wall of the insertion port 3. The opening 5 of the container 4 is located on the upper end surface of the cover plate 2, and a gap is left between the bottom of the container 4 and the bottom of the inner cavity of the base 1.

[0024] In order to facilitate observation of the amount of water contained in the base 1 , the base 1 is made of a transparent material.

[0025] When in use, the container 4 is taken out from the inner cavity of the base 1, water is poured into the inner cavity of the base 1 through the insertion hole, and then the container 4 is inserted into the inner cavity of the base 1 from the insertion port 3, so that the cover plate 2 covers the base 1. During the process of the container 4 being inserted into the inner cavity of the base 1, the air in the inner cavity of the base 1 and the excess water will be discharged from the gap between the outer wall of the container 4 and the side wall of the insertion port 3 to the outside of the base 1. Then the utility model can be placed in a freezer to freeze, so that the water in the base 1 is frozen to form ice cubes 6. Figure 5 As shown, due to the setting of the container 4, the upper end of the ice cube 6 frozen in the base 1 has a groove, and the container 4 is located in the groove, so that the ice cube 6 covers the container 4 all around without dead angles, thereby increasing the contact area between the container 4 and the ice cube 6. When biological tissue is placed in the container 4, the ice cube 6 covers the container 4 without dead angles, which can improve the refrigeration performance of the ice cube 6 in the base 1 on the biological tissue placed in the container 4.
